1. A method of adjusting flicker of a liquid crystal panel, comprising:
Step 1, providing a Nth liquid crystal panel to be implemented with flicker adjustment, and providing optimized voltage values of common electrodes of 1st to N−1th liquid crystal panels, and the variable N is an integer larger than 10; Step 2, counting a mathematical expectation μ and a standard deviation σ of the optimized voltage values of common electrodes of 1st to N−1th liquid crystal panels; Step 3, setting an initial range (VL, VH) of adjusting voltage values of common electrodes, and the initial range is determined by a principle of normal distribution, wherein VL=σ−Mσ, VH=μ+Mσ, and M is a positive integer; Step 4, showing a flicker image, and writing VH, VL, (VH+VL)/2 into a random access memory of the Nth liquid crystal panel one by one, and measuring corresponding flicker values; Step 5, determining whether the flicker value corresponding to (VH+VL)/2 is a minimum among the three flicker values in the fourth step; if it is not the minimum, the Nth liquid crystal panel is an abnormal panel to be screened out, and adjustment is accomplished; if it is the minimum, the adjustment is proceeded; Step 6, writing the voltage values of common electrodes in the initial range (VL, VH) into the random access memory one by one and from low to high, and measuring corresponding flicker values; Step 7, selecting a voltage value of common electrode corresponding to a minimum of the flicker values to be written into a read only memory of the Nth liquid crystal panel, and the adjustment is accomplished. |
