The Intel Atom Z6xx sequence chip (PDF Link) features a 45nm processor core, and 3D pictures and movie capabilities.The chip has 512K of L2 cache, IBM computer Battery 24K of L1 info and 32K instruction cache.

Intel says the Atom Z6xx sequence will help search engines Android, MeeGo and Moblin Linux. Interestingly, there’s no mention o fWindows support.

The Z6xx sequence will consist of numerous totally different chips, which includes a 1.5GHz edition for handhelds and smartphones and also a 1.9GHz edition for tablets.

The chips will characteristic Intel GMA 600 graphics, having a 400MHz pictures root and help for hardware decoding of H.264, MPEG4 component 2, WMV, and VC1 video, in inclusion to hardware help for encoding MPEG4 and H.264 video. GMA 600 also capabilities OpenGL help for 3D pictures and facilitates inside displays with resolutions of 1024 x 600 or 1366 x 768 pixels.

While it appears like the brand new chips are solo root processors, inspiron 6400 battery ,inspiron 6000 battery, they do help hyper-threading, which implies which you should certainly see enhanced overall performance with apps that help multithreading — as well as your running program may well statement which you have a few of CPUs even although you don’t.

One from the most fascinating capabilities is the truth that the Z6xx sequence facilitates always-connected technologies which will allow you obtain incoming cellular calls,inspiron 6400 battery ,inspiron 6000 battery, e-mail messages, or other info on the smartphone or tablet even once the product is idle. There’s help for WiFi, 3G, and WiMAX connections.

Laptop newspaper reviews that Intel is promising gadgets utilizing this chipset will in all likelihood be in a placement to final for as very much as 48 several hours of constant audio tracks playback or ten times of idle power. movie playback is an additional story, topping out at just five hours.

Update: Engadget obtained term from Intel how the corporation strategies to help the “full glass windows experience” on Atom… even though it is not definitely obvious if that implies we are able to anticipate the Z6xx to help glass windows or not. It does start looking like glass windows cellular seven is out from the picture, for now at least.
The write-up arrive from d630 battery ,d830 Battery

Some of you all those pre-ordered the brand new 10-inch Aspire 1 may well be receiving just a little added bonus, courtesy of Acer. IBM ThinkPad R51 Battery, based on corporation representatives, the initial batch of Aspire Ones-including evaluation units-inadvertently shipped having a 5800-mAh (milliamp-hour) six-cell computer battery .
Needless to say, we have been incredibly impressed when our program notched seven several hours and 57 mins of runtime on our computer Battery check (continuous internet surfing more than Wi-Fi).

Turns out, the Aspire 1 was designed to dispatch having a six-cell, 4400-mAh Inspiron 4000 battery , which implies it shops very much much less power compared to 5800-mAh d630 battery ,d830 Battery (for a much better explanation than I can give, go here). although Acer estimates how the 4400-mAh battery will get about six hours, our personal info recommend that it may well be anyplace from 4.5 several hours to 5.5 hours. Other netbooks with 4400-mAh batteries, the MSI Wind U100 and Wind U120, obtained 5:13 and 4:28 hours, respectively, when we ran our battery check on them.

Considering that Acer will not be upping the value to the solutions using the larger-capacity battery, people who can snag 1 of those Aspire One’s with extra-long endurance may have a specific thing of the collector’s product on their hands. because there’s no method to know (without breaking into Acer’s supply system) how countless 5800 mAH batteries C1295 , D5318 , 6Y270 are out there, it is sort of the crap shoot regarding regardless of whether you will get one.

How could you inform if you are among the fortunate ones? merely pop the gk479 , fk890 away the back. when the name reads “5800 mAh,” you are a winner! So work now! offers are limited!

What sort of batteries dell gk479 , fk890 4 are saved in wonderful conditions?

According to IEC standards, the battery ought to be at a temperatures of twenty +-5O ° C, humidity of (65 – +20)% below the circumstances of storage. In general, the greater the temperatures from the battery storage space capability from the remainder from the reduce rate. In contrast, as well. Refrigerator temperatures in 0-10O ° C once the storage space battery from the most excellent places, specifically for any battery.

Holiday Laptop Shopping Tips

Many people choose to buy a laptop online, where shoppers can find a wider selection and typically lower prices. That's fine, but you really shouldn't buy a new computer sight unseen if you can avoid it. Write down the names of some of the models you're interested in, along with a few notes about why they caught your eye, and head to your local big-box electronics store. See if the store has display units of any of the systems you're considering, or at least very similar models by the same manufacturer. Try the keyboard--can you type easily on it? Is the touchpad a pain to use? Does the screen look good? If the laptop you want to buy has a glossy screen,longe battery life,inspiron 1520 battery ，vostro 1500 battery look at other models with glossy screens and determine whether your gift recipient might prefer that look over a matte, antiglare finish.

Pick up the laptop you want to buy, and evaluate its heft. Close the lid and see if the size is something that the recipient can fit into their chosen bag (don't actually put it in a bag, of course, unless you want security all over you). Bear in mind that many display notebooks in stores have the battery removed, which makes them seem considerably lighter.

Once you have a feel for your desired laptop (or a very similar one), you can go back home and buy online with confidence. If you're buying in a brick-and-mortar store, you might want to ask if the retailer has any sales coming up, or at least call around to different stores to see which one has the best price. Or use your mobile phone to check the latest prices online, and see how competitive the in-store price is. The store you prefer might even match the price of a local competitor.

Need More RAM? Do It Yourself

Let's say that the laptop you want to buy comes with 2GB of RAM but is expandable to 4GB,9cells inspiron 1520 battery ，vostro 1500 battery. You might be able to save some money if you upgrade the laptop's RAM yourself instead of buying the 4GB option from the manufacturer. See how much more it costs to buy the machine with 4GB, and compare that with buying the RAM separately and installing it (the task typically requires removing only a couple of screws and about 5 minutes of your time--it's easy to do on most laptops today).

Naturally, you'll have to do a little homework first. Make sure that the laptop has an empty RAM socket (ask a sales rep if you're not sure), and find out what type and speed of RAM you'll need. If all of this seems intimidating, it's okay--just buy the system with the RAM upgrade. Your time and frustration are worth only so much.

Know Which Accessories to Get
If your gift recipient will need a spare battery, select one that is specifically made to work with the particular model of laptop. It's not a bad idea to buy the battery right when you purchase the PC--especially if you're buying online, where an extra battery may be offered as an option. Use caution if you buy an aftermarket battery from a manufacturer other than the one that made the laptop: Some of these batteries are priced really well but store less energy. Read user reviews and comments about third-party batteries,gk479 , fk890 carefully to make sure you're not sacrificing battery life to save a few bucks.

As for external optical drives, don't feel obligated to buy one from the manufacturer of the laptop. External optical drives that connect via USB are generally universal, so look around for a good price.

Among other laptop accessories, consider buying a small, wireless travel mouse. Even the best touchpad can be a nuisance at times, and you can find tons of compact,inspiron 15 battery, inspiron 1525 battery battery-operated wireless mice that are specifically designed to travel with a laptop. If your gift recipient wants to use a laptop mouse on an airplane, however, be aware that wireless versions are forbidden--they'll need a wired model for use in-flight.

You can probably avoid spending cash on a specialized laptop bag or carrying case, which retail stores often mark up quite a lot. Unless you encounter a great bargain, or you find a special case made just for the unusually large or small laptop you're buying and the gift recipient would love to have it, bide your time. Buying a really great bag is a whole other process in itself--don't get something the person will hate just because it's expedient and convenient.

If the salesperson tries to push other folderol on you, like screen wipes, blank discs, and extra cables, just say "no thanks." These items almost always carry a high markup in stores, and you're usually better off buying them online if you don't think you need them right away.

When In Doubt, Go Faster

If, after going hands-on with a few laptops, you're just not sure whether your gift recipient needs a faster processor, dedicated graphics, or more RAM, take the leap. Nobody ever complained that their laptop was too fast, but spending the next couple of years working on an annoyingly sluggish laptop will get old in a hurry. Expect software to become ever more resource-hungry over time, too; the applications that the laptop's new owner will use next year will likely be a little more demanding than what they use today. And if they have an HDTV or they're considering buying one in the future, an HDMI output on the laptop may come in handy.

Laptops are a little different than most consumer electronics and desktop computers in that they're, well, highly portable. People tend to throw them into bags, toss them around, accidentally knock them off tables, leave them to be poked and prodded by kids, and put them on the kitchen table, begging to be victimized by a horrific spill. Know your gift recipient and the environment where they'll use their laptop. If you think they have a high probability of destroying their laptop inspiron 15 battery, inspiron 1525 battery within a couple of years, you might want to consider the extended warranty. (When we last surveyed readers on their satisfaction with extended warranties, we found that consumers who purchased them were very satisfied.) Also, laptop theft protection plans may be a good idea for college students, who have their laptops lost or stolen with alarming regularity.

Cycle Battery life at elevated charge voltages

Chargers for cellular phones, laptops and digital cameras bring the Li-ion battery to 4.20V/cell. This allows maximum runtime, and the consumer wants nothing less than optimal use of the battery capacity. The industry, on the other hand, is more concerned with longevity and prefers lower voltage thresholds. Satellites and electric vehicles are examples where longevity is important.

We have limited information by how much lower charge voltages prolong battery life; this depends on many conditions, as we have learned. What we do know, however, is the capacities. At a charge to 4.10V/cell, the battery holds a capacity that is about 10 percent less than going all the way to 4.20V/cell. In terms of optimal longevity, a charge voltage limit of 3.92V/cell works best but the capacity would be low. Besides selecting the best-suited voltage thresholds, it is also important that the inspiron 1520 battery ，vostro 1500 battery does not stay in the high-voltage stage for a long time and is allowed to drop after full charge has been reached.

The voltage threshold of commercial chargers cannot be changed, and making it adjustable would have advantages, especially for laptops as a means of prolonging battery life. When running on extended AC mode, the user would select the “long life” mode and the battery would charge to only, say, 4.05V/cell. This would get a capacity of about 80 percent. Before traveling the user would apply the “full charge mode” to bring the charge to 4.20V/cell. This saturation charge would take about an hour and would fill the inspiron 1520 battery ，vostro 1500 battery to 100 percent capacity.

Realizing the stress on the battery, some laptop and cellular phone manufacturers choose an end-of-charge voltage that is less than 4.20V/cell. A slightly larger pack compensates for the reduced runtime. Another option to extend battery life is removing the pack from the laptop when running on the power grid. The Consumer Product Safety Commissionadvises the public to do this out of concern for overheating and causing a fire. Removing the battery has the disadvantage of losing unsaved work on power failure.

Heat buildup is always a concern and running a laptop in bed or on a pillow may contribute to this by restricting airflow. Not only will heat stress electronic components, elevated temperature causes the electrodes in the battery to react with the electrolyte and this will permanently lower the capacity. Placing a ruler or other object under the laptop to increase floor clearance improves air circulation around the enclosure and keeps the unit cooler.

The question is often asked: Should I disconnect my laptop from the power grid when not in use? Under normal circumstances this should not be necessary because once the lithium-ion battery is full, a correctly functioning charger will discontinue the charge and will only engage when the inspiron 15 battery, inspiron 1525 battery voltage drops to a low level. Most users do not remove the AC power, and I like to believe that this practice is safe.

Everyone wants to keep the battery as long as possible and use it in a way that is least stressful. This is not always feasible. Sometimes we need to run the battery in environments that are not conducive to optimal service life. As a doctor cannot predict how long a person will live based on diet and activity alone, so also does the life of a battery vary, and it can always be cut short by an unexpected failure. Batteries and humans share the same volatility.

To get a better understanding of what causes irreversible capacity loss in Li-ion batteries,inspiron 15 battery, inspiron 1525 battery, several research laboratories* are performing forensic tests. Scientist dissected failed batteries to find suspected problem areas on the electrodes. Examining an unrolled 1.5-meter-long strip (5 feet) of metal tape coated with oxide reveals that the finely structured nanomaterials have coarsened. Further studies revealed that the lithium ions responsible to shuttle electric charge between the electrodes had diminished on the cathode and had permanently settled on the anode. This results in the cathode having a lower lithium concentration than a new example, a phenomenon that is irreversible. Knowing the reason for such capacity loss might enable battery manufacturers to produce future batteries with longer life spans.

Power loss through Protection Circuit
Besides common aging, a Li-ion gk479 , fk890 battery can also fail because of undercharge. This occurs if a Li-ion pack is stored in a discharged condition. Self-discharge gradually lowers the voltage of the already discharged battery and the protection circuit cuts off between 2.20 and 2.90V/cell. Some chargers and battery analyzers (including those from Cadex) provide a wake-up feature, or “boost,” to re-energize and recharge these seemingly dead Li-ion batteries.

IE9 best at sparing your laptop battery

After some real-world tests, Microsoft has concluded IE9 is the most energy-efficient of the major browsers on the market.

Microsoft compared its new browser with Opera 11, Firefox 4, Chrome 10, and Safari 5 on an Intel laptop, measuring how many watts the machine consumed with the browser idling, showing a news site, and running graphics-intensive Web tests.

The upshot: IE9 is the most efficient in the test, meaning it'll take the smallest toll on the gk479 , fk890 battery.

"We hope and encourage the industry and other browser vendors to follow us on the path to a more power efficient Web," said Walter VonKoch, Matthew Robben, and Jason Weber, three Microsoft personnel involved in power and performance matters.

There's plenty wiggle room in the study, of course--your mileage may vary in any number of ways. The tests were on Windows 7--but how does Safari fare on a Mac? IE9 has lots of hardware acceleration features that can reduce power consumption--but Firefox 4 and later other browsers offer some hardware acceleration on Windows XP, too. Microsoft's selection of Web sites may not represent the sites where you actually spend time. Different computers have different power consumption and power-saving characteristics. And of course in the real world, most people run more software than just a browser.

But the results are valuable nonetheless. I applaud Microsoft for setting up a test and for caring about power consumption.

It makes sense to cut power usage from an environmental and financial perspective, needless to say, but better gk479 , fk890 battery life is more important for the average person. Students moving around campus and traveling businesspeople don't always have the luxury of a power outlet on hand.

largest production of Battery

Today, Yichun News (Reporter para Chunxiu) November 9, Jiangxi Province, Li-ion New Energy and Industrial Base in Yichun park grand opening, marking the Yichun to create “Asian lithium-all” the goal one step closer. The nation’s first officially settled in Lithium-Ion battery industrial base Yichun .

The development of new energy lithium battery(gk479 , fk890 ) industrial base to follow the world’s new energy, new materials, new impetus for development and utilization of new trends, particularly in lithium battery research and development is of concern in. Lithium-Ion battery of new energy industries have been the Jiangxi provincial committee and government attach great importance to have been included in Jiangxi Province, four multi-billion dollar projects and provincial key development industries. November 9, the nation’s first officially settled in Lithium-Ion battery industrial base Yichun, Jiangxi province.

Lithium Jiangxi Province New Energy and Industrial Base planning area of 20 square kilometers (30,000 acres), in just a few months, new energy has been the United States, China’s home, Foster and other power projects in more than 20 lithium-signed admission contract signing more than 10 billion yuan of funds.

Test Methods Provide Dissimilar Readings

During the last 20 years, three basic battery rapid test methods have emerged: DC load, AC conductance and multi-frequency electro-chemical impedance spectroscopy (EIS). All methods are resistance based, a characteristic that reveals the battery's ability to deliver load current. Internal resistance provides useful information in detecting problems and indicating when a battery should be replaced. However, the battery often drops below the critical 80% level set by IEEE before the condition can effectively be detected. Neither does resistance alone provide a linear correlation to the battery's capacity. Rather, the increase of cell resistance relates to aging.

When measuring the internal resistance of brand new VRLA cells from the same batch, variations of 8% between cells are common. Manufacturing process and materials used contribute to the discrepancies. Rather than relying on an absolute resistance reading, service technicians are asked to take a snapshot of the cell resistances when the laptop battery is installed and then measure the subtle changes as the cells age. A 25% increase in resistance over the baseline indicates a performance drop from 100% to about 80%. Battery manufacturers honor warranty replacements if the internal resistance increases by 50%.

Before analyzing the different test methods, let's briefly brush up on internal resistance and impedance, terms that are often used incorrectly when addressing the conductivity of a battery.

Resistance is purely resistive and has no reactance. There is no trailing phase shift because the voltage and current are in unison. A heating element is such a pure resistive load. It works equally well with direct current (DC) and alternating current (AC).
Most electrical loads, including the inspiron e1405 battery, contain a component of reactance. The reactive part of the load varies with frequency. For example, the capacitive reactance of a capacitor decreases with rising frequency. A capacitor is an insulator to DC and no current can pass through. The inductor, on the other hand, acts in the opposite way and its reactance increases with rising frequency. DC presents an electrical short. A battery combines ohmic resistance, as well as capacitive and inductive reactance. The term impedance represents all three types.

The battery may be viewed as a set of electrical elements. Figure 1 illustrates Randles' basic lead-acid battery model in terms of resistors and a capacitor (R1, R2 and C). The inductive reactance is commonly omitted because it plays a negligible role in a battery at low frequency.


Figure 1: Randles model of a lead acid battery.
The overall inspiron 1545 battery resistance consists of pure ohmic resistance, as well as inductive and capacitive reactance. The values of these components are different for every battery tested.

Battery rapid test methods and how they work

Let's now look at the different battery test methods and evaluate their strengths and limitations. It is important to know that each method provides a different internal resistance reading when measured on the same inspiron 640m battery. Neither reading is right or wrong. For example, a cell may read higher resistance readings with the DC load method than with a 1000-hertz AC signal. This simply implies that the battery performs better on an AC than DC load. Manufacturers accept all variations as long as the readings are taken with the same type of instrument.

DC load method: The pure ohmic measurement is one of the oldest and most reliable test methods. The instrument applies a load lasting a few seconds. The load current ranges from 25-70 amperes, depending on battery size. The drop in voltage divided by the current provides the resistance value. The readings are very accurate and repeatable. Manufacturers claim resistance readings in the 10 micro-ohm range. During the test, the unit heats up and some cooling will be needed between measurements on continuous use.


Figure 2:DC load method.
The true integrity of the Randles model cannot be seen. R1 and R2 appear as one ohmic value.

AC conductance method: Instead of a DC load, the instrument injects an AC signal into the inspiron e1505 battery. A frequency of between 80-100 hertz is chosen to minimize the reactance. At this frequency, the inductive and capacitive reactance converges, resulting in a minimal voltage lag. Manufacturers of AC conductance equipment claim battery resistance readings to the 50 micro-ohm range. AC conductance gained momentum in 1992; the instruments are small and do not heat up during use.

Figure 3: AC conductance method.
The individual components of the Randles model cannot be distinguished and appear as a blur.

Multi-frequency electro-chemical impedance spectroscopy (EIS): Cadex Electronics has developed a rapid-test method based on EIS. Called Spectro, the instrument injects 24 excitation frequencies ranging from 20-2000 Hertz. The sinusoidal signals are regulated at 10mV/cell to remain within the thermal battery voltage of lead acid. This allows consistent readings for small and large batteries.

Figure 4: Spectro method.
R1, R2 and C can be measured separately, enabling the estimation of battery conductivity and capacity

Spectro is the most complex of the three methods. The 20-second test processes 40 million transactions. The instrument is capable of reading to a very low micro-ohms level. With stored matrices as reference, Spectro is capable of providing gk479 , fk890 battery capacity in Ah, conductivity (CCA) and state-of-charge.

The EIS concept is not new. In the past, EIS systems were hooked up to dedicated computers and diverse laboratory equipment. Trained electrochemists were required to interpret the data. Advancements in data analysis automated this process and high-speed signal processors shrunk the technology into a handheld device.

Capacity measurements

DC load and AC conductance have one major limitation in that these methods cannot measure capacity. With the growing demand of auxiliary power on cars and trucks and the need to assess performance of stationary batteries non-invasively, testers are needed that can estimate battery capacity. Cadex has succeeded in doing this with car batteries. The company is working on applying this technology to stationary batteries.

Figure 5 reveals the reserve capacity (RC) readings of 24 car batteries, arranged from low to high on the horizontal axis. The batteries were first tested according to the SAE J537 standard, which includes a full charge, a rest period and a 25A discharge to 1.75V/cell during which the reserve capacity was measured (black diamonds). The tests were then repeated with Spectro (purple squares) using battery-specific matrices. The derived results approach laboratory standards.


Some people claim a close relationship between battery conductivity (ohmic values) and capacity. Others say that internal ohmic readings are of little practical use and have no relation to capacity. To demonstrate the relationship between resistance and capacity, Cadex Electronics has carried out an extensive test involving 175 automotive batteries in which the cold cranking amps (CCA) were compared with the RC readings. CCA represents the conductivity of the battery and is closely related with the internal resistance.

Figure 6 shows the test results. The CCA readings are plotted on the vertical Y-axis and the RC on the horizontal X-axis. For ease of reading, the batteries are plotted as a percentage of their nominal value and are arranged from low-to-high on the X-axis.

Internal resistance (represented by CCA) and capacity do not follow the red line closely and fail to provide accurate capacity readings.

Extend Battery Life for Mobile Devices

Pop believes that, along with improvements in display technology, the nanotube PCM memory could increase an iPhone's energy efficiency so it could run for a longer time on a smaller battery, or even to the point where it could run simply by harvesting its own thermal, mechanical or solar energy -- no battery required.

And device junkies will not be the only beneficiaries.

"We're not just talking about lightening our pockets or purses," Pop said. "This is also important for anything that has to operate on a battery, such as satellites, telecommunications equipment in remote locations, or any number of scientific and military applications."

In addition, ultra-low-power memory could cut the energy consumption -- and thus the expense -- of data storage or supercomputing centers by a large percentage. The low-power memory could also enable three-dimensional integration, a stacking of chips that has eluded researchers because of fabrication and heat problems.

The team has made and tested a few hundred bits so far, and they want to scale up production to create arrays of memory bits that operate together. They also hope to achieve greater data density through clever programming such that each physical PCM bit can program two data bits, called multibit memory.

Technophiles who have been dreaming of mobile devices that run longer on lighter, slimmer batteries may soon find their wish has been granted.

University of Illinois engineers have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than similar available memory. The technology could give future portable devices much longer laptop battery life between charges.

Led by electrical and computer engineering professor Eric Pop, the team will publish its results in an upcoming issue of Science magazine and online in the March 10 Science Express.

"I think anyone who is dealing with a lot of chargers and plugging things in every night can relate to wanting a cell phone or laptop whose batteries can last for weeks or months," said Pop, who is also affiliated with the Beckman Institute for Advanced Science and Technology at Illinois.

The flash memory used in mobile devices today stores bits as charge, which requires high programming voltages and is relatively slow. Industry has been exploring faster, but higher power phase-change materials (PCM) as an alternative. In PCM memory a bit is stored in the resistance of the material, which is switchable.

Pop's group lowered the power per bit to 100 times less than existing PCM memory by focusing on one simple, yet key factor: size.

Rather than the metal wires standard in industry, the group used carbon nanotubes, tiny tubes only a few nanometers in diameter -- 10,000 times smaller than a human hair.

"The energy consumption is essentially scaled with the volume of the memory bit," said graduate student Feng Xiong, the first author of the paper. "By using nanoscale contacts, we are able to achieve much smaller power consumption."

To create a bit, the researchers place a small amount of PCM in a nanoscale gap formed in the middle of a carbon nanotube. They can switch the bit "on" and "off" by passing small currents through the nanotube.

"Carbon nanotubes are the smallest known electronic conductors," Pop said. "They are better than any metal at delivering a little jolt of electricity to zap the PCM bit."

Nanotubes also boast an extraordinary stability, as they are not susceptible to the degradation that can plague metal wires. In addition, the PCM that functions as the actual bit is immune to accidental erasure from a passing scanner or magnet.

The low-power PCM bits could be used in existing devices with a significant increase in battery life. Right now, a smart phone uses about a watt of energy and a laptop runs on more than 25 watts. Some of that energy goes to the display, but an increasing percentage is dedicated to memory.

"Anytime you're running an app, or storing MP3s, or streaming videos, it's draining the battery," said Albert Liao, a graduate student and co-author. "The memory and the processor are working hard retrieving data. As people use their phones to place calls less and use them for computing more, improving the data storage and retrieval operations is important."


The team is continuing to work to reduce power consumption and increase energy efficiency even beyond the groundbreaking savings they've already demonstrated.

"Even though we've taken one technology and shown that it can be improved by a factor of 100, we have not yet reached what is physically possible. We have not even tested the limits yet. I think we could lower power by at least another factor of 10," Pop said.

The work was supported in part by the Marco Focus Center Research Program, a Semiconductor Research Corporation entity, and by the Office of Naval Research. Graduate student David Estrada was also a co-author.

3-D smartphones

Orlando, Florida (CNN) -- After a lukewarm reception from television buyers, 3-D technology is pushing its way onto small screens.

As Nintendo plans to launch with the first major gadget that can show three-dimension visuals without the need for special glasses in the U.S. on Sunday, two large Asian electronics manufacturers are following suit.

HTC has unveiled the EVO 3D, a follow-up to Sprint Nextel's breakout smartphone. It has a 4.3-inch touchscreen, which can display eye-popping 3-D without needing glasses. Users will also be able to capture photos and videos in 3-D using a pair of cameras on the back.

Like the original EVO, the 3D version will run Google's Android operating system and connect to Sprint Nextel's fast 4G data network.

LG Electronics has been working for a year and half on a 3-D smartphone of its own, said Yongseok Jang, the South Korean company's vice president of strategy.

The Optimus 3D, as it's been called, will launch on AT&T Mobility's network with the name Thrill 4G. AT&T says it will be available in the "coming months," and a price hasn't been set.

LG developers spent a great deal of time fine-tuning the pair of 5-megapixel cameras to accurately capture 3-D media, Jang said. Calibrating the cameras to produce good-looking stills and video is more difficult than pulling off a glasses-free display, he said.

The EVO 3D prototype we tested at the CTIA Wireless conference this week shot blurry video. HTC is still working on that aspect, which will probably take several more months to perfect, said Trevor Van Norman, a Sprint marketing director. The EVO 3D will be available this summer, he said.

Nintendo's 3DS also has a pair of cameras for capturing scenes in 3-D, and it works quite well. Being the first out of the gate to offer a mainstream glasses-free 3-D gadget, Nintendo expected to find competitors, and it soon did when LG announced its phone.

"I wasn't frustrated or irritated by it," Hideki Konno, a Nintendo producer who played a key role on developing the 3DS, said through a translator in a recent interview. "I mean, considering the technology was out there in the world, I wasn't even really surprised by it."

The Japanese game company plans to fend off competitors by partnering with media publishers that can offer more games and movies in 3-D.

"You need not only the capabilities; you need the content," Reggie Fils-Aime, Nintendo of America's president and operating chief, said in an interview. "They're not going to have the great gaming content that we have."

For their phones, LG and HTC are lobbying game developers to create 3-D software for Google's Android smartphone platform. Owners also will be able to download the thousands of games already available for Android.

LG expects to include a few games packaged with the Thrill 4G and have at least 10 games available when the device is made available to purchase, Jang said. With a team led by Jang, LG also persuaded Google to make YouTube videos produced with 3-D cameras available in a separate app and allow the phone's users to upload their own, Jang said.

"Instead of being at the mercy of Hollywood studios to bring 3-D content, why don't we enable our customers to create their own 3-D content?" Jang said. Google's YouTube team also helped LG tweak the quality of the videos produced by the phone, he said.

The EVO 3D will have about a half-dozen 3-D games at launch in addition to the full "Green Hornet" film, Van Norman said. The phone will also have the YouTube 3D application.

HTC touts on its website: "You look better without the 3D glasses," as a hand tosses a pair into a trash can. LG's initiative, too, was designed to eliminate the need for wonky glasses, Jang said.

"All our TV guys and our mobile-phone guys, we try to solve that problem -- to force people to wear glasses," Jang said. "Watching 3-D stuff should not be a sit-up experience."

Both LG and HTC are planning to debut tablet computers that can, like their phones, capture 3-D with a pair of cameras. However, the tablets require users wear dorky, two-toned glasses in order to view the 3-D content.

HTC's tablet, with its 7-inch touchscreen that requires glasses for 3-D viewing, is called the EVO View 4G and will be available on Sprint.

Jang from LG, which is bringing a tablet to T-Mobile USA's network, said implementing glasses-free 3-D on the G-Slate's 9-inch screen was "a cost issue."

However, by enabling the device to capture 3-D pictures and video, Jang hopes the excitement carries over into LG's TV business, which has struggled to sell 3-D sets.

T-Mobile, the G-Slate's exclusive carrier, believes that it's still "early days" for 3-D technology and that issues will be solved over time with new devices, said Desmond Smith, a senior product manager for the company.

Samsung Electronics hasn't ventured into the mobile 3-D territory yet. "There has been a big push for (3-D) on the TV side, but we haven't done anything on the phone side," said spokesman Kim Titus.

Omar Khan, the strategy chief for Samsung Telecommunications, said mobile devices will be more valuable in the 3-D space as a way to capture content in that format, rather than to view it. "I think it's still pretty early," he said.
