New screen adds memory to reduce power

Sharp has developed a new LCD technology that dramatically reduces power consumption.
Although the current screen is only 1.35in large and monochrome, and is aimed at small portable and solar powered applications, there is potential for the technique to be used to reduce power in larger LCDs.
The Memory LCD uses a memory cell in the column driver so that only the pixels that haven't changed are refreshed. This cuts power from 2mW for a typical 1.35in monochrome screen to 15µW in the Memory LCD, a dramatic reduction of 130 times
Sharp uses its proprietary Continuous Grain Silicon technology to make the screen, which at the moment is only 96 by 96 pixels. However, Sharp is a leading maker of LCDs for mobile, so expect this to be moving into larger monochrome screens for book readers, small colour screens and then to screens capable of handling video.
