Anti-reflection and anti-radiation eye protection screen for computer liquid crystal display

Abstract

The invention discloses a novel anti-reflective radiation-resistant eye-protecting screen of a liquid crystal display of a computer and a production process of the novel anti-reflective radiation-resistant eye-protecting screen. The eye-protecting screen comprises an eye-protecting substrate and two fixators, the eye-protecting substrate comprises a piece of K9 optical glass, and an anti-reflective AR coating film, an anti-static coating, a tawny eye-protecting blue-light coating film and a magnetron sputtering ITO (indium tin oxide) electric-conducting coating film are arranged on the outer surface of the glass sequentially. Each fixator comprises an L-shaped body, threaded holes are formed in one side of the L-shaped body, an elongated-slot type through hole is formed in a rim position of the other side of the L-shaped body, and an anti-shedding groove is formed in the inner bottom surface of the elongated-slot type through hole. The eye-protecting substrate is connected with the two fixators through screws and hexagon nuts, a nut stabilizer is arranged on each two hexagon nuts in pair, a slot fixing strip is inserted into each elongated-slot type through hole in a supporting manner, and anti-shedding double-faced adhesive tapes are arranged in the anti-shedding grooves and on the back faces of the slot fixing strips. The novel anti-reflective radiation-resistant eye-protecting screen has the advantages of breakage proofing, resistance to scratch, knocking and radiation and anti-reflection by combining the K9 optical glass subjected to toughening treatment with a multi-layer nanometer coating, no need for physical anti-static treatment and reliability in fixing by a double fixing mode.

Description

technical field [0001] The invention relates to the technical field of computer liquid crystal display accessories, in particular to an anti-reflection, anti-radiation eye protection screen for a computer liquid crystal display. Background technique [0002] In view of the problem that many workers need to face the computer LCD screen for a long time, radiation damages the eyes, there are many anti-radiation eye protection screens on the market, and their filters are mostly plastic, ABS and other materials, and there are many fixing methods. It adopts shoulder fixed type, which is inconvenient to install and fix. [0003] A new type of computer liquid crystal display anti-radiation filter screen (patent number: 201420290191.5) mentioned a filter screen, which uses K9 optical glass, and adopts a single fixed design with a frame.

Problems solved by technology

[0002] In view of the fact that many workers need to face computer LCD screens for a long time, radiation is more harmful to the eyes. There are many anti-radiation eye protection screens on the market. The filters are mostly made of plastic, ABS and other materials, and there are many ways to fix them. It adopts double-shoulder fixed type, which is inconvenient to install and fix.

[0003] A new type of anti-radiation filter screen for computer liquid crystal display (patent number: 201420290191.5) mentioned a filter screen, which uses K9 optical glass, and adopts a single fixed design with a frame. The disadvantage is that K9 optical glass products are easy to Fragmentation problem, the design with frame is easy to cause the display content to be blocked, because the frame is made of aluminum alloy, the four corners of the process problem are relatively sharp, which is easy to cause scratches, and the single fixing method is easy to cause the problem of product falling off, using K9 optics The thickness of the glass is 2mm without tempering, so it cannot be effectively protected against damages such as scratches, punctures by foreign objects, and external force impacts. Once damaged, the entire piece of ordinary K9 optical glass needs to be replaced, and the replacement cost accounts for 70% of its production cost. above, the higher the relative risk of damage

The anti-radiation eye protection screen adopts the anti-static treatment of physical wires and needs to use a guide, which makes installation and use inconvenient. Moreover, the filter screen has no effective anti-reflective function, and its function is relatively single, which cannot adapt to the current market.
