Embodiment Construction
[0028] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.
[0029] Please refer to figure 1 , a method for adjusting the brightness of the backlight provided in this embodiment is applicable to the scene where the brightness of the backlight of the display device is adjusted in a high-brightness mode (such as HDR mode), and the method can be performed by a device for adjusting the brightness of the backlight, a...

The embodiments of the invention disclose a method for adjusting backlight brightness, a device for adjusting backlight brightness, an apparatus and a storage medium. The method includes the followingsteps that: target brightness data corresponding to each area of a display device are determined according to the bright field area information and dark field area information of an image to be displayed, the sum value of the target brightness data is not greater than the sum value of original brightness data, wherein the original brightness data are brightness data of the image to be displayed under a non-highlighting mode; and the backlight brightness of each area of the display device is adjusted according to the target brightness data. According to the method of the invention, control isperformed, so that the sum value of the target brightness data of the display device under a highlighting mode is not greater than the sum value of the original brightness data of the display device under the non-highlighting mode; the backlight brightness of each area of the display device is adjusted according to the target brightness data; and therefore, the backlight brightness of the displaydevice is adjusted under the premise that the total power consumption of the display device does not increase, and therefore, the color saturation, contrast, and peak brightness of the display deviceunder the highlight mode can be improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a method, device, device and storage medium for adjusting the brightness of a backlight. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) panel is a kind of passive "illuminant". Its principle is that the light emitted by the backlight source behind the LCD panel displays brightly colored images after passing through the LCD panel. [0003] Since the LED (Light Emitting Diode, Light Emitting Diode) backlight has the characteristics of small size, high luminous efficiency, and flexible combination, the LED backlight has been widely used in LCD flat panel TVs. There are currently two types of LCD modules in mass production, one is the side-type LCD module, which places the LED backlight on the upper and lower sides or both sides of the TV middle frame; the other is the direct-type LCD module, which puts the LED backl...
