6 Bit 420 Channel Tft-lcd Source Driver Semiconductor

The KS0678 is a 420 channel output, TFT-LCD source driver for 64 gray scale Displays Data input is based on digital input consisting of 6 bits by 6 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 10 (5-by-2) external power supplies. Because the output dynamic range is as large as 4.8 - 7.8 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. KS0678 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 45 MHz at a 2.7 V Logic operation. it CAN be applied to the TFT-LCD panel of SXGA+(1400 * RGB) standards. By Samsung Semiconductor, Inc.
