[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 As shown;

[0030] A liquid crystal display screen with a protective function comprises a shell 1 and a liquid crystal display screen body 2 mounted on the shell 1.

[0031] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "when an object hits the LCD screen, especially children, who are naughty or curious, will touch or scratch the surface of the LCD screen with a pen tip or sharp objects. Sometimes, when toys are accidentally thrown at the LCD screen, the surface of the LCD screen will be scratched and damaged, affecting the use of the LCD screen. In severe cases, the entire LCD screen will be damaged. A TV LCD screen accounts for 90% of the total cost. Once the LCD screen is damaged, it will cause great economic losses." Combined with actual use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a winding protection component 6 and a limit component 7 are added on this basis.
