Abstract
A liquid crystal display panel and a grayscale voltage compensating method thereof are provided. The compensating method includes: obtaining an actual voltage distribution of a common voltage on a common electrode; and compensating positive polarity grayscale voltages as well as negative polarity grayscale voltages of respective pixel electrodes according to the actual voltage distribution to make that: for a same grayscale value, a difference value between the compensated positive polarity grayscale voltage of each pixel electrode and the common voltage on an opposing position of the pixel electrode on the common electrode is equal to a difference value between the compensated negative polarity grayscale voltage of the pixel electrode and the common voltage on the opposing position. By the above method, the invention can eliminate the flicker phenomenon when the liquid crystal display panel is displaying and therefore the display effect is improved.
