Overview Weltrend Semiconductor, Inc. WT8811/WT8811S Specification The WT8811 LCD (Liquid Crystal Display) Monitor Controller is an input format converter for the TFT-LCD Panels or LCD-TV applications. It accepts analog RGB signals from PC, YUV from digital video decoder or digital RGB graphics from PanelLink TMDS receiver and transforms these signals to TFT-LCD panel to display. The WT8811 performs image scaling on 24bit RGB or YUV data stream and feeds these scaled pixels to the output LCD panel. When displaying the image, instead of using external memory chips for scaling and temporary storage, the chip is using embedded line buffers. This chip also embedded MCU and flash memory such that the total system cost can be kept to minimum. In order to provide the plug-n-display, the chip also performs functions like automatic input mode detection and automatic phase calibration. This is designed to keep the sampling clock of ADC is synchronized with the incoming data so that the final image in the LCD panel is free of distortion. The chip also provides the circuitry for contrast / brightness adjustment and gamma tables for intensity correction. Figure 1 shows a system configuration for the chip.
