Abstract
A demura method for a display panel includes the steps: obtaining brightness data of a display image at a gray scale value; calculating the brightness data of the display image to obtain demura data of the pixel; dividing bits of the demura data of the pixel into first bits and second bits according to a bit length of the pixel, setting an integer gray scale value of the pixel according to the first bits, and setting a mixed gray scale value of the pixel according to the second bits.

A demura method for a display panel, comprising:
- obtaining brightness data of a display image displayed by the display panel at a given gray scale value;
- calculating the brightness data of the display image to obtain demura data of each pixel of the display panel;
- and
- dividing bits of the demura data of each pixel into first bits and second bits according to a bit length of the pixel of the display panel, setting an integer gray scale value of each pixel according to the first bits, and setting a mixed gray scale value of each pixel according to the second bits,
- wherein a bit length of the second bits is corresponding to a total frame number, wherein the total frame number is a sum of a number of frames displaying a value of the integer gray scale value plus one and a number of frames displaying the integer gray scale value for each pixel.
