摘要： A method and a circuit for driving a display panel, and a display device are disclosed. The display panel includes rows of sub-pixels. The method includes a display process, which includes: generating an initial driving signal for each row of sub-pixels according to image information of an image to be displayed; adjusting the initial driving signal for each row of sub-pixels according to a compensation gain of each row of sub-pixels, so as to obtain a target driving signal, the compensation gain of each row of sub-pixels is an actual brightness coefficient of the row of sub-pixels with respect to a reference row of sub-pixels during the display panel displaying an image with a test gray scale; and driving each row of sub-pixels to display according to the target driving signal for the row of sub-pixels, so as to enable each row of sub-pixels to reach target brightness.

摘要： Provided are a method for driving a display panel, and a display device. The method includes: obtaining a gray scale value of each sub-pixels in a current row and a gray scale value of each sub-pixels in a previous row; determining a target gray scale value of each sub-pixel in the current row according to the gray scale value of each sub-pixel in the current row, the gray scale value of each sub-pixel in the previous row, and a target compensation value in a predetermined target compensation lookup table; and inputting a data voltage into a data line in the display panel according to the target gray scale value of each sub-pixel in the current row, to charge with a corresponding data voltage to each sub-pixel in the current row.
