INTRODUCTION

The NT7108 is a LCD driver LSI with 64 channel outputs for dot matrix liquid crystal graphic

display systems. This device consists of the display RAM, 64 bits data latch, 64 bit drivers and

decoder logic. 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 NT7108 composed of the liquid crystal display system in combination with the NT7107.
