"Pixel Qi claims its power-saving, transflective LCDs are finally on sale in "specialized products," and will be more widely available soon. The displays work in both color and monochrome e-paper modes, and are said to require less than half the power of an ordinary display.

"Pixel Qi (pronounced "Pixel Chee"), which describes itself as a "fabless developer of a new class of screens," is a spinoff from OLPC (One Laptop Per Child), where the former's founder Mary Lou Jepsen is said to have invented the XO-1 laptop's sunlight-readable display technology. Pictured below, the technology allows a portable computer's screen to be switched from a standard, backlit color mode to a reflective monochrome mode, saving power and allowing the device to be used even in direct, strong sunlight.

"Unlike the electrophorescent displays offered by E Ink Corporation, Pixel Qi's screens use conventional LCD technology. Thus, they require at least some power whenever they're on."
