ABSTRACT:
A method of adjusting the brightness of a display device is provided. The method includes providing a plurality of saturated level-adjust voltages to various level adjustments of the display device when the central brightness is saturated. Then, a computation of the saturated level-adjust voltage of each level adjustment is carried out to obtain a display voltage of each level adjustment. Thereafter, a computation of the saturated level-adjust voltage, a common voltage and the display voltage of each level adjustment is carried out to obtain a feed-through voltage for each level adjustment. After that, a computation of the feed-through voltage and the saturated level-adjust voltage of each level adjustment is carried out to obtain a liquid crystal capacitance value for each level adjustment. Finally, a simulation of the liquid crystal capacitance value of each level adjustment is carried out to obtain an optimized level-adjust voltage for each level adjustment.
