Mura compensation method for display panel and display panel

A display panel, comprising:

• a first storage unit, for storing a plurality of compensation values of the display panel performing mura grayscale compensation, the plurality of compensation values corresponding to compensation by the display panel for different grayscales, wherein the compensation value corresponding to a lowest grayscale gmin among different grayscales being a first compensation value a;
• a first obtaining unit, for obtaining a head compensation value m corresponding to grayscale 0, wherein m being not 0;
• a second obtaining unit, for obtaining a current grayscale of the display panel;
• a processing unit, for performing:
• if the current grayscale of the display panel obtained by the second obtaining unit being between grayscale 0 and the lowest grayscale gmin, performing linear interpolation based on the first compensation value a and the head compensation value m to obtain a first target compensation value corresponding to the current grayscale;
• a compensation unit, for, based on the first target compensation value, performing compensation to the current grayscale of the display panel.
