    摘要： The present disclosure provides a compensation method and compensation device for a display screen, and a display device. The compensation method includes: adjusting a charging time for a plurality of areas of the display screen so that the charging time for each area to be charged is positively related to a distance from the each area to a data voltage input terminal of the display screen; comparing a first grayscale value before compensation of a sub-pixel in an i-th row and j-th column with a second grayscale value input to a sub-pixel in an (i-1)-th row and j-th column, where i and j are both positive integers, and i>1; searching a grayscale compensation parameter corresponding to the first grayscale value and the second grayscale value from a grayscale compensation parameter table in a case where the first grayscale value is not equal to the second grayscale value; compensating the first grayscale value by the grayscale compensation parameter to obtain a third grayscale value; and inputting the third grayscale value to the sub-pixel in the i-th row and j-th column for display. In the present disclosure, it is possible to allow that the display screen when displaying an image may reach a desired target grayscale value, thereby improving the display effect.

    摘要： A shift register unit and a drive method thereof, a gate driving circuit and a display device are provided. The shift register unit (100) includes an input circuit (110), a pull-up node reset circuit (120), an output circuit (130) and a coupling circuit (140). The input circuit (110) is configured to charge a pull-up node (PU) in response to an input signal; the pull-up node reset circuit (120) is configured to reset the pull-up node (PU) in response to a reset signal; the output circuit (130) is configured to output a first clock signal to a first output terminal (OUT1) under control of a level of the pull-up node (PU); and the coupling circuit (140) is configured to control, by coupling, a potential of the pull-up node (PU) in response to a second clock signal. The shift register unit can reduce a falling edge time of the output signal of the first output terminal, thereby improving the driving capability of the shift register unit.
