TEL: 886-6-505-0880 FAX: 886-6-505-0891 DOC No:HX8802-DS HX8802A/HX8802B 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 TFTLCD 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. 2. Features 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. Built-in gamma correction function. Built-in polarity inverted function. Line inversion driving scheme. Provide source and gate drivers control timing. Shift clock signals for the source driver(3-φ clock). Provide flip and mirror scan control. Optional 3.3V input and output level. Single supply voltage: +5.0V 64 or 48 pins LQFP.
