262K Color Single-Chip TFT Controller/Driver

1. Introduction

The ST7787 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 Serial

Peripheral Interface (SPI), 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 circuits necessary to drive liquid crystal,

it is possible to make a display system with the fewest components.

2. Features

ꢀ Single chip TFT-LCD controller/driver with display data RAM

ꢀ Display resolution: 240(H) x RGB x 320(V)

ꢀ Display data RAM (frame memory): 240 x 320 x 18-bits = 1,382,400 bits
