Controller HX8258 datasheet - M-COMP

HX8258-A1200/1026 CH TFT LCD Source Driverwith TCONVersion 02 January, 20071. General DescriptionHX8258-A is a 1200/1026 channel outputs source driver with TCON, and 3-wireSerial Port Interface. It also supports 3-chip cascade mode to extend source channelto be 3072-channel outputs (resolution: 1024RGB x 768).The interface follows digital 24-bit parallel RGB input format. The TCON generatesthe 400x240, 800x480, 800x600, 1024x600 and 1024x768 resolutions and provideshorizontal and vertical control timing to source driver and gate driver. It also supportsdithering feature, apply source driver with 6-bit DAC to perform 8-bit resolution 256gray scales.The source driver receives 6-bit by 3 dots of digital display data per clock from TCONand generates corresponding 64-level gray scale voltage output. Since the outputcircuit of this source driver incorporates an operational amplifier with low powerdissipation, and performs wide voltage supply range and small output deviation.Therefore, a high quality display with less crosstalk can be achieved.Himax ConfidentialThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.1-January, 2007
