TFT-LCD TCON with DAC
March, 2004, Version 06
1. General Description
The HX8802A/HX8802B is a TFT-LCD timing controller with built-in gamma
correction and DAC circuits. It provides horizontal and vertical control timing to TFT-
LCD source and gate drivers. With built-in DAC and operational amplifiers, this
controller performs gamma correction and polarity inverted function to convert digital
RGB data into analog amplified and alternated RGB signals for TFT-LCD panel.
Support different display resolution modes, up to 1440 x 234.
Support two types of panel group.
Master clock frequency: 30 MHz max.
Support NTSC/PAL TV system.
