INTRODUCTION
The S6C0641 is a 300 channel or 309 channel output, TFT-LCD source driver for 64 gray scale displays. Data
input is based on digital input consisting of 6 bits by 3 dots, which can realize a full-color display of 260,000 colors
by output of 64 values gamma-corrected.
This device has an internal D/A (Digital-to-Analog) converter for each output and 9 or 11 external power supplies.
S6C0641 can be adopted to larger panel, and SHL (Shift Direction Selection) pin makes use of the LCD panel
connection conveniently. Maximum operation clock frequency is 55 MHz at a 3.3 V logic operation. It can be
applied to the TFT-LCD panel of SVGA, XGA standards.
