Mura compensation method for display panel and display panel

A display panel, comprising:

• first storage unit, for compressing on an array basis of n*m pixels, storing a default mura compensation value corresponding to a first pixel in each area, wherein, n and m being integers greater than or equal to 2;
• a calculation compensation unit, for, based on the default mura compensation value, performing linear interpolation calculation to obtain mura compensation values for pixels in the same area other than the first pixel, and performing mura compensation to the display panel;
• a first obtaining unit, for, after performing mura compensation to the display panel, obtaining information of an X-th area still having mura phenomenon, wherein the X-th area belonging to an area formed by compression on an array basis of n*m pixels of the display panel;
• a second obtaining unit, for, obtaining a final grayscale compensation curve equation;
• a calculation unit, for, based on the default mura compensation value and the final grayscale compensation curve equation, calculating to obtain supplementary mura compensation values for pixels in the X-th area other than the first pixel;
• and
• a compensation unit, for, based on the default mura compensation value and the supplementary mura compensation values, re-performing the mura compensation to the X-th area.
