Abstract: A data driver including a receiver, a skew adjusting circuit and a processing device is provided. The receiver samples image data on a data bus according to a processed pixel clock signal. The image data includes pixel data during active periods and a test pattern repeatedly inserted in the image data during blanking periods. The skew adjusting circuit receives a pixel clock signal and adjusts a clock phase of the pixel clock signal by delaying the pixel clock signal with a controllable skew according to a feedback control signal so as to generate the processed pixel clock signal. The processing device stores a predetermined test pattern synchronized with the inserted test pattern, determines an optimum skew by comparing the sampled test patterns with the predetermined test pattern, and generates the feedback control signal including information indicating the optimum skew.

Abstract: A method for accessing a single port memory is provided. A single port memory is used as a line buffer and divided into a plurality of memory blocks. The line buffer data is written into or read out from these memory blocks by turns with a special sequence corresponding to the operation mode; for example, a normal mode or a PLM mode. Therefore, the line buffer data can be written into or read out from the line buffer at the same time, and the size and cost of integrated circuit can be reduced.

Abstract: An apparatus for driving a display panel is provided. The apparatus is adapted to a LCD panel. The apparatus at least has a processor, a first and second timing controllers and a first and second group of source drivers. Real pixels are input from an input port of the processor. The real pixels are converted to impulsive pixels with a pre-determined frame rate. The impulsive pixels are divided into two groups of pixels by the processor. The two groups of pixels are simultaneously sent to the source drivers though two timing controllers, respectively. Finally, the source drivers generate driving voltages for the display panel.
