Display screen technology developer Mary Lou Jepsen is working at her new start-up to create laptop PCs so energy efficient they'll be able to run on a standard laptop battery for 20 to 40 hours before needing a recharge.
Jepsen, formerly the head of Intel's display division and chief technology officer at One Laptop Per Child (OLPC), plans to start shipping ultra-low power screens for laptops and e-books in the second half of next year that people can read in direct sunlight and have a fully saturated HDTV-quality color mode.
Low-power screens that can be read in bright sunlight are one of the key features on OLPC's XO laptop. The screens cost a third that of traditional LCD screens and use about a tenth of the power.
"At Pixel Qi, we have a new series of inventions that go well beyond the OLPC screen that we are developing right now," said Jepsen by e-mail. Her company recently opened offices in Taipei and San Francisco after receiving a first round of funding.
More energy efficient screens are critical for mobile devices such as laptops and e-books because screens are among the most power hungry components on such devices.
Pixel Qi plans to develop entire laptop and PC designs around its new screen technology to create the most power efficient models possible.
