"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."
