Blue light preventing computer display screen

Abstract

The invention relates to a blue light preventing computer display screen which comprises a frame. The frame is fixedly connected with a display screen body, and the display screen body sequentially comprises a liquid crystal display, a blue light preventing optical film, a polarizing film, an anti-scratching protection film, a blue light preventing coating and a blue light absorbent from inside tooutside. The right side of the frame is fixedly connected with a first connecting rod, the first connecting rod is fixedly connected with a universal joint, the other end of the universal joint is fixedly connected with a second connecting rod, and the bottom of the second connecting rod is fixedly connected with a rotary disc. The rotary disc is movably connected with the top of a base, a sliding way is arranged on the rear side of the frame, and the sliding way is movably connected with a third connecting rod. The third connecting rod is fixedly connected with a clamping block, a clamping groove is formed in one side of the third connecting rod, and the bottom of the frame is fixedly connected with a fourth connecting rod. The blue light preventing computer display screen is reasonablein structure and high in functionality, and the user experience of a user can be improved.

Description

technical field [0001] The invention relates to an anti-blue light computer display screen, which belongs to the technical field of computer display screens. Background technique [0002] The display screen is usually also called a monitor. A display is an I / O device belonging to a computer, that is, an input and output device. It is a display that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. Tool, short-wave blue light is light with a wavelength between 400nm-450nm and relatively high energy. In work and life, computers are often used, but the existing computer display screens generally do not have the effect of anti-blue light, which will cause great damage to the eyes after long-term use, and sometimes in a dimly lit environment , the visibility of the keyboard is relatively low, which affects normal work, and it is often necessary to use the computer to display documents in work meetings....

In work and life, computers are often used, but the existing computer display screens generally do not have the effect of anti-blue light, which will cause great damage to the eyes after long-term use, and sometimes in a dimly lit environment , the visibility of the keyboard is relatively low, which affects normal work, and it is often necessary to use the computer to display documents in work meetings. Since the inclination of the display screen cannot be adjusted, it is very inconvenient to use, and when the display screen needs to be rotated, only Turning the display by turning the base reduces the life of the base
