Abstract:
1. A driving method of a liquid crystal display (LCD), the LCD comprising: an LCD panel, the LCD panel comprising: a plurality of scan lines; a plurality of data lines; and a plurality of pixels, each pixel being connected to a corresponding scan line and a corresponding data line, and each pixel comprising a switching device connected to the corresponding scan line and the corresponding data line; and the method comprising: (a) measuring reaction curves of the pixels of the LCD panel switched from any gray scale value to other gray scale values in a frame period, and generating a standard table according to the reaction curves measured; (b) measuring adjustment gray scale values of any gray scale value for different gammas; (c) generating a plurality of tables according to the adjustment gray scale values and the standard table; (d) applying scan voltages to the scan lines; (e) receiving image data from an image signal terminal; (f) delaying the image data for a frame period in order to generate delayed image data; (g) selecting a table from the standard table and the tables according to gamma; and (h) selecting an image data value from the selected table according to the current image data and the delayed image data and generating a data line voltage according to the image data value, applying the generated data line voltage on a corresponding data line.
