HD66764
176-channel Common Driver for Color Displays
Rev.1.0
September, 2001
Description
The HD66764 is a common-driver LSI for systems with color-liquid-crystal dot-matrix graphic
displays. It incorporates 176 LCD drive circuits and power-supply circuits. An external capacitor is
also needed for the liquid crystal display.
This LSI, when used with the HD66763 384-channel segment driver with on-chip RAM, is suitable for
color displays of cellular phones to a maximum of 128-by-176 dots.
