Embodiment Construction

[0071] The application discloses a method for adjusting the brightness of a backlight source.

[0072] A method for adjusting the brightness of a backlight source, such as figure 1 As shown, it includes the following steps:

[0073] S1. Obtain the brightness of the current ambient light, and compare the brightness of the current ambient light with a preset basic brightness to obtain a comparison result.

[0074] The brightness of the current ambient light refers to the brightness of the external ambient light of the display, and the brightness of the current ambient light is acquired by the first brightness sensor 8 installed on the display. The default basic brightness refers to the basic brightness at which the user can see the screen clearly.

[0075] At the same time, in order to determine the brightness adjustment standard of the backlight source 7 to meet the basic brightness requirements for users to see the display screen clearly under different ambient light brightn...

Abstract

The invention relates to the technical field of backlight sources, in particular to a backlight source brightness adjusting method, system and device and display equipment, and the method comprises the steps: obtaining a human body sensing signal and the brightness of ambient light, and employing the human body sensing signal and the brightness of the ambient light as dual judgment conditions, and therefore, the brightness of the backlight source not only can be adjusted by generating a dimming instruction according to the brightness of the ambient light, but also can be finely adjusted by generating an adjusting instruction according to the human body sensing signal and the brightness of the ambient light, so that the brightness of the backlight source adapts to different users, the comfort of the users when the users use the display is improved, the brightness of the backlight source can be adjusted according to different actual conditions of light sensitivity of users, so that actual requirements of different users on the brightness of the backlight source are met.

Description

technical field [0001] The present application relates to the field of backlight technology, in particular to a method, system, device and display device for adjusting brightness of a backlight. Background technique [0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It includes liquid crystal glass and a light source. The light source is generally installed on the back of the liquid crystal glass. Light sources make up the picture. Wherein, the luminous source is a backlight, and its luminous effect directly affects the visual effect displayed on the liquid crystal display. [0003] The luminous effect of the backlight is mainly determined by the brightness of the backlight. At present, the brightness of the backlight is generally adjusted by manually touching the LCD display. Each time, the brightness of the backlight needs to be manually adjusted according to the environment. more inconvenient. [0004] In order t...
