Embodiment Construction
[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some of the embodiments of the present disclosure, not all of them. Based on the described embodiments of the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative effort fall within the protection scope of the present disclosure. Herein, the technical term "grayscale" means a grayscale level, for example, a grayscale value within a grayscale value range of 0 to 255.
[0028] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the usual meanings understood by those skilled in the art to which the present disclosu...

The present disclosure provides a display device and a display control method. The device includes a backlight module, first and second display panels, and a processing unit, and is configured to: obtain a sub-pixel grayscale matrix of an image to be displayed; The grayscale-brightness curve determines the expected brightness distribution map; according to the grayscale situation corresponding to each partition in the sub-pixel grayscale matrix, the set brightness of the Mini-LED is determined; based on the light diffusion coefficient of the Mini-LED in all partitions, the first a corrected brightness distribution map; determine the pixel grayscale of the first display panel in the partition according to the brightness difference in each partition in the first corrected and expected brightness distribution map; based on the light diffusion coefficients of the Mini-LEDs in all partitions and The occlusion coefficient of the first display panel is used to obtain a second corrected brightness distribution map; the gray scale of the second display panel is adjusted according to the brightness difference between the second corrected and expected brightness distribution map at each pixel of the second display panel. This reduces halos and light leakage, enhances contrast and peak brightness, and improves display performance.
Description
technical field [0001] The present disclosure relates to the display field, and in particular, to a display device and a display control method. Background technique [0002] At present, the display device formed by the combination of a common backlight module and a double-layer display panel can achieve The effect of improving the contrast ratio, but the brightness of this display device is low, the peak brightness has always been its bottleneck, and there are problems of halo and light leakage. In the display device formed by the combination of the backlight module and the double-layer display panel, there is still room for improvement in terms of reducing halo and light leakage and improving color rendering capabilities. Contents of the invention [0003] Aiming at the above-mentioned technical problems existing in the prior art, the present disclosure provides a display device and a display control method, the display device includes a backlight module, and a first di...
