Compensation method for Mura

A Mura compensation method, comprising:

• in step 10, obtaining a first image of a display panel captured with a predetermined grayscale value “S0” by a camera;
• in step 20, obtaining an initial Mura compensation value “M0” of each Mura pixel on the display panel according to the first image basing on the predetermined grayscale value “S0”;
• in step 30, determining whether the initial Mura compensation value “M0” satisfies a relation:
• −N≤M0≤N, wherein “N” indicates a predetermined grayscale compensational range, and “N” is a natural number;
• in step 40, configuring the initial Mura compensation value “M0” of each Mura pixel as a target Mura compensation value in response to −N≤M0≤N, and conducting a Mura compensation process on each Mura pixel according to the target Mura compensation value;
• or performing step 50 in response to the relation:
• −N≤M0≤N being not satisfied;
• in step 50, determining whether a maximum value “M1” and a minimum value “M2” of the initial Mura compensation value “M0” of each Mura pixel satisfy a relation:
• M2>0, N<M1≤2N, or a relation:
• M1<0, −2N≤M2<−N;
• in step 60, selecting a first grayscale value “S1” and obtaining a first Mura compensation value “Ms1” according to the first grayscale value “S1” in response to M2>0, N<M1≤2N, or M1<0, −2N≤M2<−N, controlling the first Mura compensation value “Ms1” of all of the pixels to satisfy a relation:
• −N≤MS1≤N, configuring the first Mura compensation value “Ms1” of all of the pixels as the target Mura compensation value, and conducting the Mura compensation process according to the target Mura compensation value.
