( DOC No. HX8257-A-DS ) 480X272 TFT LCD Single Chip Digital Driver Preliminary Version 01, December 2007 480X272 TFT LCD Single Chip Digital Driver December 2007 1. General Description HX8257-A is a single chip digital driver supporting 480RGBX272 or 480RGBX240 resolution. The single chip includes Source, Gate, TCON, and Power circuits. The driver receives 24-bit digital display data with single clock edge and generates corresponding 64 level gray scale voltage outputs with dithering function to realize 16M colors display. Positive and negative polarity voltages can be alternately output from each channel in line (row) inversion driving method. HX8257-A can be applied on dual gate TFT LCD panel. Source line is half with 720 channels and gate line is double with 544 or 480 channels.
