Abstract

This utility model relates to the field of LCD screen dustproof technology and discloses a dustproof protection structure for LCD screens, including an LCD display screen. A dustproof mechanism is provided above the LCD display screen, and mounting mechanisms are provided on the left and right sides of the LCD display screen. The dustproof mechanism includes a dustproof component, a reset component, a disassembly component, and a positioning component. The dustproof component is located above the LCD display screen. This dustproof protection structure for LCD screens, through the dustproof mechanism, uses a sliding plate driven by a compression spring to move a sliding rod, which in turn moves a pressure plate and a locking block downwards to fix the dustproof cover cloth in place. No external force is required. The dustproof cover cloth is fixed inside the frame to block the front of the LCD display screen, preventing dust in the outside air from directly contacting the front of the LCD display screen, thus achieving the effect of dustproofing the LCD display screen. Furthermore, the dustproof cover cloth has no strict requirements; it only needs to fit the inner side of the frame and its length completely cover the front of the LCD display screen.

Description

Dustproof protection structure for LCD screen

Technical Field

The utility model relates to the technical field of LCD screen dust prevention, in particular to a dust prevention protection structure for an LCD screen.

Background

The LCD is constructed by placing liquid crystal in two parallel glass sheets, arranging a plurality of vertical and horizontal tiny wires between the two glass sheets, and controlling the rod-shaped crystal molecules to change direction by electrifying or not to refract light to generate pictures. The basic principle of the screen display is that liquid crystal material is filled between two parallel plates, the arrangement state of molecules in the liquid crystal material is changed by voltage, so as to achieve the purposes of shading and transmitting light to display images with different depths and different staggers, and a three-element color filter layer is added between the two parallel plates to realize the display of color images.

In daily use scenes, dust is not in holes, and common protective measures are difficult to block invasion. In an office environment, although relatively clean, fine dust generated when printers and copiers operate, as well as dust carried by people walking, gradually accumulate on the surface of the LCD screen. This is more serious in environments where dust is large, such as factories. A large amount of dust adheres to on the screen surface, not only influences the display definition, can also lead to the screen to be infected with the spot more easily because of electrostatic adsorption, greatly influences visual experience. The dust entering the screen may interfere with the normal operation of the electronic components, causing display failures such as bright spots, dark spots, color patches, etc., and shortening the service life of the LCD screen.

The difficulty in maintenance and replacement of the dust-proof components is also a major problem. The current LCD screens are often not reasonably designed with dust-proof components and are very complex to operate once cleaned or replaced. Some dustproof screens are fixed at positions which are difficult to access, special tools are needed during disassembly, and even part of the screen structure is disassembled, so that the maintenance cost is increased, and secondary damage to the screen is easily caused by improper operation. Moreover, because the replacement process is cumbersome, many users often ignore the periodic maintenance of the dust-proof components, resulting in a gradual decrease in the dust-proof effect over time, and an inability to continue to provide effective protection for the LCD screen.
