Problems solved by technology

[0002] In the current local dimming (Local Dimming) solution, the way of backlight dimming is usually adopted. Due to the nature of light diffusion, the light sources in each zone will interact with each other, and it is impossible to accurately control the dimming backlight brightness of each zone. It is easy to cause halo phenomenon around the bright area, which brings great difficulty to data compensation. It is difficult to accurately control the backlight brightness and data compensation of each partition, and the visual effect is not good.

Abstract

The invention provides a double-screen dimming method and a display device. Double screens include a dimming screen and a display screen. The dimming screen comprises a plurality of dimming areas, thedisplay screen includes a plurality of display areas, and the dimming areas correspond to the display areas in a one-to-one way. The double-screen dimming method comprises the steps that regional characteristic values of the dimming areas are determined according to image data, and the dimming brightness of the dimming areas is determined according to the regional characteristic values; accordingto the correspondence relation of the image data and gray scale and target brightness, the target brightness of each display area is determined; the opening rate of each display area is determined according to the target brightness and corresponding dimming brightness; according to the opening rate and the corresponding relation between the gray scales and the opening rate, the target gray scaleof each display area is determined for data compensation. The double-screen dimming method achieves accurate control of backlight brightness adjustment and data compensation and improves the vision effect.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a dual-screen dimming method and a display device. Background technique [0002] In the current local dimming (Local Dimming) solution, the way of backlight dimming is usually adopted. Due to the nature of light diffusion, the light sources in each zone will interact with each other, and it is impossible to accurately control the dimming backlight brightness of each zone. It is easy to cause halo phenomenon around the bright area, which brings great difficulty to data compensation. It is difficult to accurately control the backlight brightness and data compensation of each partition, and the visual effect is not good. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a dual-screen dimming method and a display device that improve visual effects through precise control of backlight brigh...
