Description

Technical Field

[0001] The invention relates to the field of liquid crystal televisions, in particular to a liquid crystal television with impact resistance. Background Art

[0002] Liquid crystal display, or LCD for short, uses a substance between solid and liquid, an organic compound with regular molecular arrangement, which becomes a transparent liquid state when heated and a turbid solid state with crystal particles after cooling. The molecular structure of liquid crystal used in liquid crystal display is arranged like a thin matchstick, which is called liquid crystal. Liquid crystal display made with this type of liquid crystal is also called LCD. Liquid crystal televisions are made by applying voltage to the liquid crystal between two sheets of glass, and reproduce the picture through changes in molecular arrangement and twists and turns. The screen creates the picture through the collision of electron groups and forms the picture through the perspective reflection of external light.

When the LCD screen is playing, the protective curtain 25 The rollers 24 are wound up on the reel 24, and then the reel 24 is rotated to the back side of the LCD TV body 1. Thanks to the existence of the damping shaft 22, the rollers 24 can be in a stable storage state without the action of external force. When the LCD screen is closed, the two rollers 24 are rotated to the front side of the LCD screen, and the protective curtain 25 is pulled open and sucked to achieve a protective effect on the LCD screen, so as to block objects that hit the screen from the front side of the LCD TV body 1, thereby having a certain impact resistance effect and reducing the probability of the LCD screen being broken.
