STK6005
1. 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.
