This is quite interesting. jkkmobile has some hands on time with the Pixel Qi’s forthcoming indoor/outdoor display. Watch the video:
“- When backlight is turned of,Pixel Qi screen uses only 0.8 watts compared to typical 2.5 watts
– Their aim is to bring the drain down to 0.2 watts in next 6 months
– When backlight is on, it is uses same amount of power as a normal screen but is much brighter.
– When backlight is turned of,Pixel Qi screen is black and white.”
Lower power, longer battery life for mobile users.
