Embodiment Construction

[0010] Attached below figure 1 , attached figure 2 The present invention will be further described.

[0011] This display includes the light sensor 2 installed on the top of the display screen 1 and the infrared human body detection switch 3, and the single-chip microcomputer arranged inside the display screen 1. The LCD backlight driving circuit is connected to the single chip microcomputer. The light sensor 2 is used to detect ambient light, and feed back the light intensity value to the single-chip microcomputer for processing. The single-chip microcomputer controls the LCD backlight drive circuit to adjust the appropriate brightness, so as to avoid excessive light and aggravate visual fatigue. When people sit down and use the computer, the infrared human body detection switch 3 can detect and feed back the switch signal to the single-chip microcomputer, and the single-chip microcomputer counts. Remind people to take a break at this time to avoid visual fatigue and dama...

Abstract

The invention relates to a display, comprising a light ray sensor installed above a display screen, an infrared human detection switch and a single-chip microcomputer arranged inside the display screen; the light ray sensor and the infrared human detection switch are connected to the single-chip microcomputer; and an LCD (Liquid Crystal Display) backlight driving circuit in the display screen is connected to the single-chip microcomputer. When a person sits down to use a computer, the infrared human detection switch can detect the person and feeds back a switching signal to the single-chip microcomputer and the single-chip microcomputer begins to timing; after a certain period of time, the single-chip microcomputer controls the LCD backlight driving circuit to turn off the backlight and the display screen becomes a black screen to remind the person to have a rest at this moment, so that the visual impairment resulting from visual fatigue is avoided.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a display. Background technique [0002] As we all know, computers are widely used in people's daily life, but using monitors for a long time may easily cause visual fatigue, especially if the brightness of the monitor is set too high, it may aggravate the damage to the visual system. Contents of the invention [0003] In order to overcome the deficiencies of the above technologies, the present invention provides an eye protection display that can automatically adjust brightness and control eye use time. [0004] The technical scheme that the present invention overcomes its technical problem adopts is: [0005] This display includes a light sensor installed on the top of the display screen and an infrared human body detection switch, a single-chip microcomputer arranged inside the display screen, the light sensor and the infrared human body detection switch are all connecte...
