Gamma tuning method, apparatus, and computer-readable storage medium

A gamma tuning apparatus, applied to a display panel comprising:

• a first display area and a second display area, the gamma tuning apparatus comprising:
• a first acquiring module, implemented by at least one processor and memory, configured to acquire a first register value of the first display area after gamma tuning under a target gray scale;
• and
• a first determining module, implemented by the at least one processor and memory, configured to determine, according to the first register value and a predetermined linear relationship between register values of the first display area and register values of the second display area, a target register value of the second display area under the target gray scale;
• wherein the first display area and the second display area respectively comprise sub-pixels of n colors, the first register value comprises first sub-register values corresponding to the sub-pixels of n colors in one-to-one correspondence, and n is an integer greater than or equal to 1;
• and
• wherein the determining, according to the first register value and the predetermined linear relationship between register values of the first display area and register values of the second display area, the target register value of the second display area under the target gray scale comprises:
• for a sub-pixel of any ith color of the sub-pixels of n colors, determining, according to the first sub-register value corresponding to the sub-pixel of the ith color and a linear relationship between a register value of the sub-pixel of the ith color in the first display area and a register value of the sub-pixel of the ith color in the second display area, a target register value of the sub-pixel of the ith color in the second display area under the target gray scale, wherein i is an integer greater than or equal to 1.
