Abstract

The preferred embodiments of the present invention provide a system and method for reducing the battery power required by a handheld device (300) that incorporates a graphical display (301). Graphical display (301), display drivers (307), LCD controller (403) and a memory (405) are optimized such that several pixels of information may be clocked simultaneously when the device is operating in a partial display mode. The optimized circuitry reduces the required refresh clock frequency (411) and thus the current drain on a device battery (319) thereby improving device operation time.
