Liquid crystal display, and method and apparatus of automatically adjusting flicker of the same

The present invention relates to a liquid crystal display, flickering automatic adjustment method and apparatus thereof. Automatic flicker adjustment of the liquid crystal display device comprises an image pickup device for picking up the liquid crystal display device and the liquid crystal display comprising a DVR (digital variable resistor) for generating the common voltage based on the input signal is stored in the DVR verifying the default values, performing a schematic flicker measurement, obtaining a quadratic equation, and finding the solutions of the quadratic equation, performing a fine flicker measurement, selecting an optimal value, and wherein the optimum value inputting the DVR It includes. As such, to shorten the process time by the time it takes less than one second in the flicker adjustment, of course, possible to easily manage the flicker analysis and history and can evenly align the product characteristics. The liquid crystal display, flickering, default, the optimum value, average, variance, luminance, camera, computer
