Eye-protective screen

Abstract

The invention relates to an eye-protective screen for preventing fluorescent screens of computers and televisions from harming human eyes. The eye-protective screen is formed by a conductive light filtering screen mesh, a metal conductive frame, supports and a grounding wire device, wherein the conductive light filtering screen mesh is pasted and fixed on the metal conductive frame and is electrically connected with the metal conductive frame; each support is in an inverted L-shape; the vertical parts of the two supports are respectively inserted into a left side frame and a right side frame of the metal conductive frame; the horizontal parts of the supports can be rotated by adopting the vertical parts of the supports as shafts; each support is made of metal materials; the supports are inserted into the metal frame so as to be electrically connected with the metal frame; eccentric shaft fixing seats are respectively arranged on the horizontal parts of the two supports; adhesive stickers are pasted on the bottom surfaces of the eccentric shaft fixing seats; the grounding wire device is electrically connected with the supports. According to the eye-protective screen provided by the invention, low-frequency radiation and whole positive ions can be effectively shielded, most of hard light and reflected light can be absorbed, colorful patterns can be completely eliminated, and a screen image is clear and soft.

Description

technical field [0001] The invention relates to a device for preventing human eyes from being damaged by fluorescent screens of computers and televisions. Background technique [0002] The application of electrical appliances such as TV sets and computers with fluorescent screens in modern society has become increasingly common, and has been closely related to people's daily life and work. A large amount of statistical data shows that if people who have been with the screen for a long time do not pay attention to the necessary protection, their eyes and other body organs will be adversely affected. device, but because this type of device cannot be anti-static and radiation-proof, and will distort the screen scene, etc., this type of device has not been accepted by consumers so far.

Problems solved by technology

A large number of statistical data show that if people who have been with the screen for a long time do not pay attention to the necessary protection, their eyes and other body organs will be adversely affected. devices, but because such devices cannot be anti-static and radiation-proof, and will distort the screen scene, etc., such devices have not been accepted by consumers so far.

In recent years, a new type of eye protection device has been developed in China. It is to stick a cross-woven conductive filter screen on the metal conductive frame, and then connect a grounding device to the frame. Compared with the previous The protective performance of eye protection devices such as the "screen protection screen" has been significantly enhanced, but the device still has shortcomings such as unreasonable product mechanical structure, complicated manufacturing process, and faintly appearing colored patterns.
