262K Color Single –Chip TFT Controller/Driver

1. Introduction

The ST7781 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and

320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts,

8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display data RAM of 240x320x18

bits. It can perform display data RAM read/write operation with no external operation clock to minimize power

consumption. In addition, because of the integrated power supply circuit necessary to drive liquid crystal; it is possible to

make a display system with the fewest components.
