Color TFT LCD Driver

MN838898

1. Type

CMOS LSI source driver for color TFT LCD panels

2. Overview

This LSI converts the digital display data from a personal computer, portable

device, or other source into analog signals for driving a color TFT LCD panel.

3. Features

(1) Power saving driver

(2) Built in DA converter accepting 6-bit digital input (for 262,144 colors)

(3) Choice of 360 and 324 drive outputs

(4) Input data bus at pixel level

(5) Choice of output data format: gray scale or binary

(6) Eleven reference voltage inputs for producing 10 segment gamma

adjustment graph.

(7) Set output voltage inflection points at data values 00, 01, 07, 0F, 17, 1F,

27, 2F, 37, 3E, and 3F.

(8) Prechargeless drive circuits

(9) Support for serial cascade connections

(10) Automatic internal clock stop after fixed number of data inputs

(11) Choice of shift register shift direction: right or left

(12) Gray scale data inversion available every clock cycle

(13) Low voltage operation: 2.5 V (typ.) for logic circuits; 3.5 V (typ.)

for analog circuits

(14) Maximum operating clock frequency: 15 MHz

(15) Power save function for cutting off current to outputs, fixing them

at high impedance
