graphic card of a personal computer, the exact same input interface as a conventional CRT
monitor. This feature makes digital-interface LCD monitor a true replacement of a conventional
CRT monitor.
The digital input RGB signals are first received by TMDS receiver, and the 24-bit RGB data are then fed into
the SD1010D. The SD1010D 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 SD1010D then automatically scales the input image to fill the full screen of the
LCD monitor. The SD1010D 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 SD1010D implements four advanced display technologies:
1. Advanced mode detection 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.
The SD1010D also provides distinguished system features to the TFT LCD monitor solution.
The first one is “plug-and-play”, and the second one is “cost-effective system solution”. To be
truly plug-and-display, the SD1010D performs automatic input mode detection. Furthermore,
the SD1010D can generate output video even when the input signal is beyond the specifications
or no input signal is fed.
For “cost-effective system solution”, the SD1010D implements many system support features
such as OSD mixer, error status indicators, 2-wire serial interface for both EEPROM and host
CPU interface, and low-cost IC package. Another important contributing factor is that the
SD1010D does not require external frame buffer memory for the automatic image scaling and
synchronization.
Figure 1 shows the block diagram of the SD1010D as well as the connections of important
system components around the SD1010D.
