Display device, display control method and driving device

A display device, comprising:

• a backlight module comprising a plurality of backlight partitions;
• a first display panel and a second display panel sequentially arranged on a light-emitting side of the backlight module, wherein the second display panel is configured to display images, and the first display panel comprises a plurality of pixel areas corresponding to the plurality of backlight partitions, each pixel area comprises a plurality of pixel units, and each pixel unit corresponds to a plurality of pixels of the second display panel;
• and
• a processor configured to:
• acquire a pixel grayscale matrix of an image to be displayed, wherein a plurality of grayscales of the pixel grayscale matrix correspond to the plurality of pixels of the second display panel one-to-one;
• determine desired brightness of each of the plurality of pixels by using a grayscale-brightness curve of the second display panel based on the pixel grayscale matrix;
• determine set light-emitting brightness of each backlight partition according to grayscale information in the pixel grayscale matrix corresponding to each backlight partition;
• correct the set light-emitting brightness of each backlight partition, based on light diffusion coefficients of the plurality of backlight partitions, to obtain a first corrected brightness of each backlight partition;
• determine a grayscale of each pixel unit in a corresponding pixel area according to a difference between the first corrected brightness and the desired brightness of each pixel for the corresponding pixel area;
• correct the set light-emitting brightness of each backlight partition, based on the light diffusion coefficients of the plurality of the backlight partitions and shielding coefficients of the first display panel, to obtain a second corrected brightness of each backlight partition;
• and
• for each pixel of the second display panel, adjust a grayscale of each pixel of the image to be displayed according to a difference between the second corrected brightness of a corresponding backlight partition and the desired brightness of the pixel, to cause the second display panel to display the image to be displayed in adjusted grayscale.
