Embodiment Construction
[0043] Please refer to FIG. 4, which is a schematic diagram of a signal distortion compensation circuit of a transmission line of a liquid crystal display panel according to a preferred embodiment of the application. The transmission line signal distortion compensation circuit of the liquid crystal display panel includes a timing controller 30 and a frame buffer 40. According to the actual brightness change of a liquid crystal display panel 50, the brightness value to be compensated is determined, and a table corresponding to the position of the scan line is established. The timing controller 30 includes: a data line counter 301, a scan counter (not shown in the figure), a comparator 303, and a look-up table 305. First, input the pixel image data of the current frame (PresentFrame) into a timing controller 30; wherein the data line counter 301 is used to count and indicate the current data line position; and the comparator 303 is used to compare the pixel image of the current f...
