HCD61203U中文资料日立数据手册PDF规格书

描述 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.
