[Syntek Semiconductor Co., Ltd.]

GENERAL DESCRIPTION
The STK6005 chip, converting PC / Mac video images for a TFT-LCD display monitor, performs an image scaler on the RGB / YUV image data stream and outputs the scaled pixels to the LCD panel. The chip embeds line buffers for a scaling operation, so there is no external memory required. Both the OSD (On-Screen Display) circuit and the interface are embedded in this chip to support the internal and external OSD. STK6005 also provides an auto-adjustment function to automatically support the frequency & phase tuning, H / V positioning and white balance tuning. A brightness and contrast control circuit and a Gamma table correction function are also provided.
