Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention more clear, 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.
[0024] It can be understood that the terms "first", "second" and the like used in the present invention can be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present invention. Both the first client and the second client are clients, but they are not the same client.

The invention relates to a display screen back light control method, a display screen back light control device and computer equipment. The method comprises the following steps of detecting the brightness value of the back light of a display screen; judging whether the brightness value is smaller than the brightness threshold value or not; if so, switching the integrated circuit current output mode of the back light into an index mode; if not, switching the integrated circuit current output mode of the back light into a linear mode, wherein in the index mode, the integrated circuit current value of the back light and the brightness value of the back light form the index relationship, and in the linear mode, the integrated circuit current value of the back light and the brightness value of the back light form the linear relationship. The display screen back light control method, the display screen back light control device and the computer equipment have the advantages that if the brightness value is smaller than the brightness threshold value, the integrated circuit current output mode of the back light is switched into the index mode; when the value is lower than the brightness threshold value, the integrated circuit current output consistency of the back light is ensured; the dark shadow due to backlight display non-uniformity at the edge of the display screen can be avoided.
Description
technical field [0001] The invention relates to the field of electronic equipment backlight control, in particular to a display screen backlight control method, device and computer equipment. Background technique [0002] Backlighting is a form of lighting that is often used in liquid crystal displays. When the electronic device is in use, the display screen of the body emits a backlight so as to display the content more clearly. In order to adapt to the light and dark changes of the surrounding environment and the user's usage habits, it is necessary to adjust the brightness and contrast of the display screen. Traditional backlights have differences in consistency under low light output conditions, resulting in uneven and dark shadows at the edges of the display. Contents of the invention [0003] Embodiments of the present invention provide a display screen backlight control method and device, which can avoid the problem of uneven backlight display and dark shadows. ...
