Last week New York City was host to the Greener Gadgets conference, a show focusing on the greening of the consumer electronics industry where panelists and companies present their ideas and products. Mary Lou Jepsen of Pixel Qi and formerly of One Laptop Per Child (OLPC) was a keynote speaker at the event.
In her address, Jepsen presented the XO laptop, the rugged and power-efficient laptop developed by OLPC and intended for children of developing nations. One of Jepsen’s specific contributions to the XO was its sunlight-readable screen, a focus she brought to Pixel Qi.
“Pixel Qi is working on getting these screens into cell phones and conventional laptops as well as the power management architecture,” says Jepsen. “By doing that, we’ll be able to create a component that can be more broadly used in a variety of products. The way to drive cost down is to make more of something.”
The sunlight-readable screen of the XO boasts low power and low cost and uses an LED back light that can be turned on and off to conserve power when needed. When the LED back light is off, the screen only uses 100 mW.
