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.

Features

• LCD drive circuits

 176 outputs

• Internal power-supply circuit

 Step-up circuit: twice to 12 times, positive-polarity inversion

 Bias setting: 1/2 to 1/13, programmable

 Contrast adjustment: 128-level programmable volume

 Dividing resistors: built-in (controls the bias)

 Setting: serial transfer from the HD66763 segment driver

• Low power consumption

• Power-supply voltage

 Vcc = 1.8 to 3.6 V

• LCD drive voltage

 VLCD-VEE = 10 to 44 V (VM standard: ± 5 to ± 2 2 V)

• Package

 TCP and chip
