Problems solved by technology

[0004] At present, when going from indoor to indoor, due to the change of ambient light intensity from weak to strong, the display information on the display screen of the mobile terminal cannot be clearly seen by human eyes; Changes, the human eye adapts slowly, and the display brightness of the mobile terminal display will cause discomfort to the human eye
[0005] It can be seen that at present, in the case of changes in the ambient light intensity, the display effect of the display screen of the mobile terminal is relatively poor.

Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] In the embodiment of the present invention, such as figure 1 As shown, the detailed method flow of the mobile terminal to adjust the display brightness of the liquid crystal display is as follows:

[0050]Step 101: the mobile terminal acquires information about changes in ambient light brightness.

[0051] During implementation, the mobile terminal obtains the ambient light brightness through the light sensor, and the mobile ter...

Abstract

The invention discloses a method and a device for adjusting display brightness of a liquid crystal display screen, which are used to improve the display effect of the display screen of a mobile terminal when the intensity of ambient light changes. The method is as follows: the mobile terminal acquires the change information of the ambient light brightness; the mobile terminal determines that the change information of the ambient light brightness is that the brightness increase per unit time exceeds a first threshold, and according to the change information of the ambient light brightness, the preset Select a characteristic curve from the set of characteristic curves, wherein the characteristic curve is obtained by increasing the offset in the brightness direction on the basis of the normalized gamma curve, and the offset in the brightness direction increases with the gray The increase of the luminance value gradually decreases; the mobile terminal uses the selected characteristic curve to adjust the brightness displayed on the display screen.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for adjusting display brightness of a liquid crystal display. Background technique [0002] With the widespread application of smart terminals, display screens have become a reuse channel for information exchange between users and smart terminals. [0003] The outdoor strong light environment is a special application scenario of the mobile terminal. Under the strong outdoor light environment, the ambient light is enhanced, and the display screen is often difficult to see due to the enhanced reflection of the display screen. Clearly display information on the display. [0004] At present, when going from indoor to indoor, due to the change of ambient light intensity from weak to strong, the display information on the display screen of the mobile terminal cannot be clearly seen by human eyes; Changes, the human eye adapts slowly, and the display bright...
