Pixel Qi to Show 7-inch, Power-saving Screen at CES

Pixel Qi is preparing a seven-inch, power-saving display for devices like tablets and e-readers, which could become available as test samples during the Consumer Electronics Show in early January, the company said.

On its product page, the company said the final specification for the screen was under development, and that it would become available in the first half of next year.

The Consumer Electronics Show will be held in Las Vegas between Jan. 6 and 9.

Pixel Qi develops hybrid displays that can absorb ambient light to brighten screens and reduce power consumption to extend the battery life of devices. In low-power mode, the displays reduce the need for the backlight, which is used to light up LCD (liquid crystal display) screens on conventional devices. The screens can take advantage of light sources like sunlight, which also helps reduce glare and improves the e-book reading experience.

The display can also function as a normal LCD (liquid crystal display) screen to display full-motion video.

The company has already shipped a 10.1-inch display for netbooks, and is aiming for a new range of devices including tablets and e-readers with the 7-inch display, the company said in a blog entry on Sept. 7. The company claims that its Pixel Qi screen is half the weight of the LCD display on Apple's iPad, but consumes much less power.

Pixel Qi is run by Mary Lou Jepsen, formerly the chief technology officer of One Laptop Per Child. Jepsen led development of a low-power screen that is now being used in OLPC's XO-1 laptop. She left the nonprofit in 2007 to start Pixel Qi with the goal to create laptops under $100 based on technologies she invented at OLPC. The company is now focusing its development on low-power screens.

Pixel Qi is also developing screens for future XO devices, including the XO-3 tablet, which will be displayed early next year.
