INTRODUCTION
The S6C0670 is a 384 / 402 channel output, TFT-LCD source driver for an 256 gray scale LCD panel. Data input
is based on digital input consisting of 8 bits by 6 dots, which can realize a full-color display of 16,700,000 color by
output of 256 values gamma-corrected.
This device has an internal D/A (Digital-to-Analog) converter for each output and 16 (8-by-2) reference voltages.
Because the output dynamic range is as large as 7.8 - 14.8 Vp-p, it is unnecessary to operate level inversion of
the LCD's common electrode. Besides, to be able to deal with dot-line inversion when mounted on a single-side,
output gray scale voltages with different polarity can be output to the odd number output pins
and the even output pins.
S6C0670 can be adopted to larger panel, and SHL (shift direction selection) pin makes the use of the LCD panel
connection conveniently. Maximum operation clock frequency is 75 MHz at 3.0 V logic operation, single edge
and it can be applied to the TFT-LCD panel of UXGA standard.
