Abstract

A power saving method of a chip-on-glass liquid crystal display. The method first (a) wakes up the source drivers of the LCD and (b) transmitting the image data and control signals from the source driver corresponding to the FPC to the farthest waked source drivers, and then switching them to power-saving mode. Steps (b) and (c) are repeated until all the source drivers are switched to power-saving mode.
