Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screens, in particular to a lifting component of a liquid crystal screen. Background Art

[0002] Liquid crystal screen, or liquid crystal display screen, is a display screen made of liquid crystal material. The LCD screen controls the arrangement of molecules inside the liquid crystal material through voltage, changes the polarization angle of light passing through the liquid crystal layer, and thus controls the displayed image. The LCD screen is mainly composed of a liquid crystal layer, backlight, filter, polarizer, glass plate and circuit board. When the LCD screen is powered on, the molecules in the liquid crystal layer are arranged in a predetermined manner to form different pixels, which display different colors and brightness through the illumination of the backlight.

[0003] The patent document with application number CN201120294386.3 discloses a new type of liquid crystal screen, which includes a liquid crystal screen, a panel connected to the liquid crystal screen, and a frame-shaped bracket, wherein the liquid crystal screen and the panel are connected as a whole through the frame-shaped bracket. The frame-shaped bracket is provided with an elastic buckle device, which is a convex U-shaped buckle piece and a concave arc-shaped spring piece arranged on the outer wall of the frame-shaped bracket, wherein the U-shaped buckle piece is used to clamp the liquid crystal screen, and the arc-shaped spring piece is used to limit the movement of the liquid crystal screen. The frame-shaped bracket is also provided with a plurality of screw holes for connecting the bracket with the panel. Based on the search of the above patent and in combination with the liquid crystal screen in the prior art, it is found that when the above liquid crystal screen is used, the liquid crystal screen does not integrate an adjustable protective structure, resulting in the screen part being directly exposed to the external environment, thereby making it more susceptible to physical damage compared to other types of display technologies. Specifically, once the liquid crystal display screen is subjected to impact or pressure, the arrangement of its liquid crystal molecules may be damaged, thereby affecting the display effect, and even causing the screen to be completely damaged.
