Embodiment Construction

[0007] In order to make the purpose of the present invention, technical solutions and advantages clearer, the present invention will be described in further detail below,

[0008] An embodiment of the present invention provides a display brightness control system, including a brightness adjustment system, a main controller and a distance detector. The main controller is electrically connected to the brightness adjustment system and the distance detector respectively. The detector is used to detect the distance between the human body on the front of the display and the display. When the distance detector detects that the distance between the human body on the front of the display and the display is less than L, 200mm≤L≤1000mm, preferably, L is 400mm. At this time, for the computer For the display, the protective effect on human vision is the best. The main controller controls the brightness adjustment system to dim the display brightness; when the distance detector detects that ...

Abstract

A display brightness control system solves the problems that, when people use computers, some people unconsciously get closeer and closer to computer displays and finally get into a bad habit, and that, when the people are too close to the computer displays, the people are easily influenced by electromagnetic radiation, and people's vision are also easily harmed. The display brightness control system comprises a brightness adjustment system, a main controller and a distance detector; the main controller are electrically connected with the brightness adjustment system and the distance detector, the distance detector is disposed on the front face of the display, and the distance detector is used to detect the distance between a human body on the front side of the display; when the distance detector detects that the distance between the human body on the front side of the display and the display is less than L, 200mm<=L<=1000mm, the main controller controls the brightness adjustment system to adjust the brightness of the display to darken; and, when the distance detector detects that the distance between the human body on the front side of the display and the display is greater than L, the main controller controls the brightness adjustment system to enable the brightness of the display to be normal. The display brightness control system belongs to the field of electronic equipment.

Description

technical field [0001] The invention relates to a display control system, in particular to a control system capable of changing the brightness of the display as the distance between the human body and the display changes. Background technique [0002] Now more and more people use computers, and everyone pays more and more attention to the electromagnetic radiation generated by computers and the impact of computers on people's vision. When using computers, some people will unconsciously get closer and closer to the computer monitor, and finally Develop a bad habit, very close to the computer monitor, that is easily affected by electromagnetic radiation, and easily hurt people's eyesight. Contents of the invention [0003] The purpose of the present invention is to provide a display brightness control system to solve the problem that when using a computer, some people will get closer and closer to the computer display without knowing it, and finally develop a bad habit of be...
