HD61203U

(Dot Matrix Liquid Crystal Graphic Display

64-Channel Common Driver)

Preliminary

Description

The HD61203U is a common signal driver for dot matrix liquid crystal graphic display systems. It

generates the timing signals (switch signal to convert LCD waveform to AC, frame synchronous signal)

and supplies them to the column driver to control display. It provides 64 driver output lines and the

impedance is low enough to drive a large screen.

As the HD61203U is produced by a CMOS process, it is fit for use in portable battery-driven equipment

utilizing the liquid crystal display’s low power consumption. The user can easily construct a dot matrix

liquid crystal graphic display system by combining the HD61203U and the column (segment) driver

HD61202U.
