example 1
[0105] As shown in Table 1, when the initial gray value of the previous frame of any backlight partition is determined to be 8, the target gray value is 0. Since the target grayscale value is already the minimum grayscale value, therefore, the adjustment of the grayscale brightness must not be performed in an overvoltage driving manner. Then, the backlight brightness can be adjusted according to the predetermined Table 1. Specifically, Table 1 is determined based on the adjustment parameter being the backlight duty cycle. From Table 1, look up the backlight duty cycle 18% corresponding to 8 and 0. Therefore, the backlight duty cycle of the backlight partition needs to be lowered by 18%, so as to realize the reduction of the grayscale brightness, so that the grayscale brightness of the current frame is closest to the ideal grayscale brightness corresponding to the target grayscale value 0 at this time , and finally achieve the purpose of improving crosstalk ghosting.

[0110]As shown in Table 2, when the initial gray value of the previous frame of any backlight partition is determined to be 8, the target gray value is 0. Since the target grayscale value is already the minimum grayscale value, therefore, the adjustment of the grayscale brightness must not be performed in an overvoltage driving manner. Then, the backlight brightness can be adjusted according to the predetermined Table 2. Specifically, Table 2 is determined based on the adjustment parameter being the backlight reference current brightness. When no adjustment is performed, the backlight reference current brightness is 300mA. Find out from Table 2 that the backlight reference current brightness corresponding to 8 and 0 is 295mA. Therefore, it is necessary to adjust the backlight reference current brightness of the backlight partition to 295mA, so as to realize the reduction of the gray scale brightness, so that the gray scale brightness of the current frame is the highest. It is ...
