64CH SEGMENT DRIVER FOR DOT MATRIX LCD
The AIP31108 is a LCD driver LSl with 64channel output for dot matrix liquid crystal graphic
display systems. This device consists of the display RAM, 64bit data latch, 64 bit drivers and
It has the internal display RAM for storing the display data transferred from a 8 bit micro
controller and generates the dot matrix liquid crystal driving signals corresponding to stored data.
The AIP31108 composed of the liquid crystal display system in combination with the AIP31107 (64
channel common driver).
