Abstract: A display panel control method, a display mode of the display panel including a normal display mode and a partial highlight display mode, the control method including obtaining display information of a display area in the display panel in the partial highlight display mode, the display information including a grayscale displayed corresponding to each pixel, and a number of pixels displaying the corresponding grayscale; determining a target gamma curve based on the display information, a difference between a display brightness corresponding to the grayscale in the target gamma curve and a target display brightness required for the pixels to display the corresponding grayscale in the partial highlight display mode being within a predetermined range; and controlling the pixels in the display area to display based on the target gamma curve.

Abstract: A brightness adjustment method and a brightness adjustment device of a display panel and a display device are provided. The brightness adjustment method of the display panel including a plurality of sub-pixels includes acquiring grayscale data received by the display panel; performing a data processing process on the grayscale data and at least inserting a plurality of transitional grayscales between a 0-order grayscale and a 1st-order grayscale to form target grayscale data; and adjusting the brightness of the plurality of sub-pixels based on the target grayscale data.
