Light used to illuminate the LCD screen turns on the gadget can be used to recharge the battery. It attempts to achieve a study.

Researchers at the University of California, Los Angeles (UCLA) are developing ways to take the wasted energy from the an LCD screen that can be used in devices such as mobile phones and others.

Technology developed at the UCLA Henry Samueli researcher School of Engineering and Applied Science is an organic photovoltaic polarizer. The concept, which used the LCD screen can be equipped with photovoltaic polarizer. Thus, any light that hit the screen it can be converted for energy.

Not coincidentally, the LCD screen, such as on a smartphone, will usually be illuminated by lights from behind (backlight). Well, about 75 percent of energy from this lamp will be wasted. Yet to turn on the lights it takes 80-90 percent of battery energy.

Each LCD has two layers of polarizers, in front of and behind the scenes. What did the researchers at UCLA is basically to make a polarizer that also serves as a modifier of light into electricity (photovoltaic cells).

Aside from the backlight lamp, the screen is equipped with photovoltaic polarizer can absorb energy from the sun or even the lamp lighting the room through the front of the screen.

"Looking ahead, we want to increase the efficiency from the organic photovoltaic these polarizers, and eventually we hope to cooperate with electronics makers to implement it in real products," said Professor Yang Yang, the principal investigator of this study.

This research was supported by Intel Labs Academic Research Office. "This approach is very attractive, and could be synergy with other projects that we fund through Intel Labs," said Youssry Bouros, program director at Intel Research Labs Academic Office.

The paper about the research will be published in the journal Advanced Materials. The paper was prepared by UCLA researchers Rhui Zhu and Ankit Kumar.

Asus has refreshed its Asus-Automobili Lamborghini VX7 laptop with new Intel Sandy Bridge processor. The co-branding joint venture laptop Lamborghini VX7 now sports a quad-core Intel processor, has Nvidia GeForce GTX 460M graphics and also gets SuperSpeed USB 3.0 ports. This time, this massive laptop will be made available in Orange, Black and Carbon Fiber color options. Just in case you have a heart to hear the price then it is $3,000 (Rs. 1,32,000 approx.) for this ultra-lux Italian supercar like laptop.

Beastly Italian sports car like Asus Lamborghini VX7 packs quad-core Intel Core i7-2630QM mobile processor coupled with Intel HM65 Express chipset. New VX7 has 15.6-inch LED Backlit display that supports full HD (1920x1080) in 16:9 aspect ratio. On this display, the full HD multimedia and gaming is powered by the Nvidia GeForce GTX 460M graphics with 3GB video memory. One can beef up to 16GB DDR3 1333Mhz RAM in four slots.

For storage, Asus provides a hybrid option that can hold up to 1.25TB of data storage with combination of SSDs and HDDs. Asus has also added a Blu-ray reader/writer so that you can enjoy your Blu-ray collection on it. This monstrous laptop accommodates USB 3.0 that provides ten times faster transfer speed compared to the USB 2.0 port.

At the side, Lamborghini VX7 has Bluetooth 2.1 sensor, Wi-Fi (802.11 b/g/n), 8-in-1 card reader, Gigabit LAN, one USB 3.0 port, HDMI port, and a VGA Port. To make this huge laptop long for hours, ASUS has incorporated 8-cell 75WHr battery. The laptop weighs around 3.82kg.

If you need to replace your old pileup of a desktop PC, the HP Pavilion 1047cb-p7 (list $ 799 at Costco) is a no-muss, no problems doing that. This system of mid-tower comes with a 23-inch monitor, and includes a handful of additional equipment. Your processor will not impress multimedia power users may find yourself limited opportunities for expansion, and there is a fair amount of bloatware on the hard disk. But otherwise, the P7-end 1047cb is an artist and the value of a well.

The design and development

P7 1047cb Pavilion is an aluminum body and black plastic, which is accentuated by glossy silver front panel framed with a plastic liner. Sliding open the door to reveal two USB 2.0 ports and jacks for headphones and microphone. On the front is starting to read memory cards: xD / Smart Media, SD / MMC, Memory Stick and Compact Flash. No DVD-Multi drive with LightScribe technology, and another empty 5.25-inch.

The back office gives up multiple connectivity options: four USB 2.0 ports, VGA, DVI-D, Ethernet, and analogue audio. The system lacks eSATA and USB 3.0 ports, but comes with 802.11n Wi-Fi. The kit comes with VGA and DVI cables for connecting up to 1 920 by 1, 080 HP 2311x screen has an HDMI port on the screen, too, but the lack of one on the computer that makes unnecessary. Because the monitor does not have built-in speakers, you should use a small pair of HP flows into or provide your own.

Cracking open the office is to loosen a screw with a Phillips screwdriver and slide the side panel. Inside you will find only two RAM slots, both filled with a total of 6 GB of DDR3 memory. There is a PCI Express (PCIe) x16, three PCIe x1 slots free, but the power of 250 watts limits you to low-end graphics cards like Radeon HD 6450 available in the HP Pavilion 1067cb P7 (list 999, $ 99, 4 stars). There are two additional SATA ports on the motherboard that could accommodate more than two hard drives, but the hard drive of 1 TB is already installed should be able to satisfy all but the most eager to download. It comes preloaded with its fair share of bloatware, but Blio, eBay, Snapfish, Kobo, Netflix, Hulu, Zino and Bing Bar.

Performance

HP Pavilion 1047cb P7 has a 2.5 GHz Intel Core i5-2400 processor and 6 GB of RAM. This combination offers a wonderful computing experience. The pavilion was able to manage our multimedia tests in time, encoding a video in Handbrake to 1 minute 29 seconds, 2 seconds after the Editors Choice HP Pavilion 1067cb P7. Both systems have the same amount of time, 3 minutes 31 seconds to apply 12 filters Photoshop CS5 in our test.

The P7-1047cb our test could not run 3DMark 11, but drove 11 frames per second (fps) in Crysis at 1280 x 720 resolution, on average retail. These results indicate that this team does not play well with high-end games in 3D, but could handle World of Warcraft, with torches, and even play of light, no problem. If you need a little more on the video front, the HP Pavilion 1067cb and p7-based discrete graphics work is a little better but not ideal for serious 3D gaming.

HP Pavilion 1047cb P7 is a business interest with the consumer in search of the whole package: PC, monitor, keyboard and mouse. And slightly altered, but not as much as, for example the Asus Essentio CM6850-07 ($ 829.99 list, 3.5 stars). Current Editors Choice P7 1067cb Hall becomes a bigger screen (25 inches) and a separate graphics card. But if your budget is limited, and graphics needs are modest, the HP Pavilion 1047cb P7 is a good way to go.
