抜粋

Liquid crystal displays (LCDs) are suitable as elements for wearable and ubiquitous computing, thanks to their low power consumption. A technique that drives LCDs with lower power is proposed. It harvests charges on the LCD and stores them in an additional capacitor for reuse when the polarity changes. A simulation shows that the technique reduces the charge requirements by up to 50%. An experiment on a prototype shows that the mduction is only partially offset by the overhead of micro-controller operation. Overall, a 30% reduction was achieved with large 1-pixel LCDs. With a small 10x10mm LCD, the overhead matched the reduction and no improvement was measured.
