Description

Technical Field

[0002] Liquid crystal display, also known as LCD, is a flat-panel display technology commonly used in televisions and computer monitors. LCD screens not only look different from bulky CRT (cathode ray tube) monitors, but they also operate very differently. Instead of firing electrons on a glass screen, LCD screens have a backlight that provides light to individual pixels arranged in a rectangular grid.

[0003] After searching, the patent document with publication number: CN220205146U discloses a liquid crystal display screen, which is provided with a threaded connection between a screw and a movable plate, and a sliding connection between a positioning rod and the movable plate, so that the rotating screw can drive the movable plate to rise and fall, and thus the height of the display screen body can be adjusted; by providing a rotating connection between the rotating plate and the display screen body, and a sliding connection between the arc-shaped limit groove and the buffer column, and the action of the counterweight block and the buffer column, it is possible to provide protective support when the display screen body is skewed, and to provide buffering through the sliding connection between the buffer chamber and the piston.

[0004] Although the above device has solved some of the existing shortcomings, in actual use, when the LCD screen is working, the electrons move to the screen, making the screen charged. The charged body has the property of attracting light and small objects, which easily attracts dust to the screen. The dust on the surface will continue to accumulate. When it accumulates to a certain extent, it will cause the LCD screen to have insufficient display effect, thereby affecting the user's viewing effect. Utility Model Content
