Display power consumption is one of the single largest drains on batteries in portable devices and the new display could help lead the way towards mobile electronics products with longer battery life.
Compared to a conventional active-matrix display, which is refreshed between 60 and 70 times per second, the ULC (ultra low power consumption) technology only sends signals when the screen image is changed. This results in a drop in power consumption to one-third conventional levels for moving images and one-thirtieth for still images, said Arisa Mori, a spokeswoman for Sharp.
Mass production of displays TFT (thin film transistor) displays featuring the ULC technology will begin in July this year. The company has not yet decided pricing. Sharp is one of Japan's leading manufacturers of LCD panels.
