Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Please refer to figure 1 , is a schematic flowchart of the first embodiment of the method for adjusting the backlight of a display device according to the present invention. The backlight adjustment method includes:

[0022] In step S11, the current ambient brightness is detected by the photosensitive sensor of the display device to obtain a photosensitive brightness value. The photosensitive sensor may be turned on by default in the background of the display device, or automatically turned on after detecting that the backlight of the display device is turned on...

Abstract

The present invention relates to the field of electronic technology and provides a backlight adjustment method of a display device. The method comprises a step of detecting current ambient brightness through the photosensitive sensor of the display device and obtaining a photosensitive brightness value, and a step of adjusting the backlight brightness of the display device according to the photosensitive brightness value and the current ambient brightness detected through the photosensitive sensor of the display device. The invention also provides the display device which is controlled according to the above method, the accurate judgment of ambient light can be realized, and a user experience is good.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for adjusting a backlight of a display device and a display device thereof. Background technique [0002] Current mobile terminal devices such as mobile phones generally have the function of automatically adjusting the brightness of the screen backlight, which is usually realized by using a photosensitive sensor. The photosensitive sensor adjusts the screen brightness by sensing the current ambient light brightness. When the ambient light is strong, the screen brightness is increased, and when the ambient light is weak, the screen brightness is decreased. [0003] In the course of realizing the present invention, the inventor finds that there are following problems in the prior art: [0004] Affected by factors such as the opening structure, glass transmittance, and differences in the light spectrum, the photosensitive sensor cannot truly reflect the light perceived...
