Description

Technical Field

[0001] The utility model relates to the technical field of display protection screens, in particular to an easily detachable liquid crystal display protection screen. Background Art

[0002] Liquid crystal displays are flat, ultra-thin display devices composed of a certain number of color or black and white pixels. They are placed in front of a light source or a reflective surface. Liquid crystal displays have very low power consumption, so they are favored by engineers and are suitable for battery-powered electronic devices. Their main principle is to use electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces, which cooperate with the back light tubes to form the picture.

[0003] The internal material of the LCD display surface is quite fragile. If it encounters external forces such as collision and pressing, it is easy to be damaged, resulting in a sharp drop in brightness and luminance. The pixels at the damaged part are broken, forming "bad pixels" that cannot be repaired. Long-term exposure can easily make the display screen covered with dust. If you use an ordinary rag or paper towel to wipe it, it will cause scratches on the screen, which will affect the display effect. Therefore, a transparent panel is installed on the LCD screen to protect it. Since the transparent panel is currently installed mostly by hooking or sticking, it is not convenient to install and remove the protective screen, which reduces the applicability of the device body. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content
