Overview
ST ST7781 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 circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
