OVERVIEW

The SD1010A is enhanced version of the SD1000 chip. It is an IC designed for analog-interface XGA TFT LCD monitors. An analog-interface LCD monitor takes analog RGB signals from a graphic card of a personal computer, the exact same input interface as a conventional CRT monitor. This feature makes analog-interface LCD monitor a true replacement of a conventional CRT monitor.

The analog input RGB signals are first sampled by three channels of 8-bit A/D converters, and the 24-bit RGB data are then fed into the SD1010A. The SD1010A is capable of performing automatic detection of the display resolution and timing of input signals generated from various PC graphic cards. No special driver is required for the timing detection, nor any manual adjustment. The SD1010A then automatically scales the input image to fill the full screen of the LCD monitor. The SD1010A can interface with TFT LCD panels from various manufacturers by generating either 24-bit or 48-bit RGB signal to the LCD panel based upon the timing parameters saved in the EEPROM.

The SD1010A implements four advanced display technologies:

1. Advanced mode detection and auto-calibration without any external CPU assist

2. Advanced programmable interpolation algorithm

3. Stand-alone mode support, and

4. Advanced true color support with both dithering and frame modulation.
