example 1
[0105] As shown in Table 1, when it is determined that the initial grayscale value of the previous frame of any backlight partition is 8, the target grayscale value is 0. Since the target grayscale value is already the minimum grayscale value, the overvoltage driving method must not be used to adjust the grayscale brightness. Then, the backlight brightness can be adjusted according to the predetermined table 1. Specifically, the table 1 is determined according to the situation that the adjustment parameter is the backlight duty cycle, and the backlight duty cycle corresponding to 8 and 0 is 18% from Table 1. , therefore, it is necessary to reduce the backlight duty cycle of the backlight partition by 18%, so as to reduce 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 it is determined that the initial grayscale value of the previous frame of any backlight partition is 8, the target grayscale value is 0. Since the target grayscale value is already the minimum grayscale value, the overvoltage driving method must not be used to adjust the grayscale brightness. Then, the backlight brightness can be adjusted according to the predetermined Table 2. Specifically, Table 2 is determined according to the situation that the adjustment parameter is the backlight reference current brightness. When no adjustment is performed, the backlight reference current brightness is 300mA. From Table 2, find 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 reduce the gray-scale brightness, so that the gray-scale brightness of the current frame is the highest.
