Control method and control device for display panel, storage medium, and electronic device

A control device for a display panel, a display mode of the display panel including a normal display mode and a partial highlight display mode, the control device comprising:

• at least one processor;
• at least one memory coupled to the at least one processor;
• and
• a bus, wherein:
• the at least one processor and the at least one memory are configured to communicate to each other through the bus, and the at least one processor is configured to call a program instruction stored in the at least one memory to:
• acquire display information of a display area in the display panel in the partial highlight display mode, the display information including a grayscale corresponding to each pixel to be displayed in a next frame, and a number of pixels to display each corresponding grayscale;
• determine a target gamma curve based on the display information including the grayscale corresponding to each pixel to be displayed and the number of pixels to display each corresponding grayscale, wherein, after the target gamma curved is determined;
• and
• control pixels in the display area to display based on the target gamma curve, wherein a difference between a display brightness corresponding to each grayscale in the determined target gamma curve and a target display brightness required for pixels to display each corresponding grayscale in the partial highlight display mode is within a predetermined range.
