Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal module backlight, and more specifically to a structure for solving the problem of diaphragm deviation. Background Art

[0002] The main function of LCM is to use liquid crystal technology to display images or information. It can receive signals from electronic devices and display images or text through liquid crystal panels. Due to its high definition, low power consumption and thin and light characteristics, LCM liquid crystal modules have been widely used in consumer electronics, industrial equipment, automotive electronics and medical equipment. In the LCM (liquid crystal module) manufacturing industry, the backlight structure is an important part of the module, which directly affects the display effect of the display screen.

[0003] The existing LCM liquid crystal module backlight structure, film material and plastic frame structure are fixed by limiters. During the terminal use or transportation of the module, the module shakes, which easily causes the film material to move and the backlight film to shift, causing defects. Due to the poor displacement of the film, the subsequent repair of the whole machine will cause a large amount of material scrapping and labor waste. Therefore, we have made improvements to this and proposed a structure to solve the film offset.

[0004] For example, a Chinese patent (publication number CN216748371U) discloses a vehicle-mounted backlight source that is easy to fix the diaphragm. Its specification discloses: the current vehicle-mounted backlight source has high product requirements and strict reliability requirements, and has stricter requirements on the stability of the product structure. The diaphragm is one of the main components of the vehicle-mounted backlight source. If the diaphragm is not fixed well, the vehicle-mounted backlight source is prone to diaphragm arching and diaphragm movement during reliability tests and actual use, resulting in product defects and affecting customer use. The above patents can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the utility model is that the shaking of the module easily causes the film material to move, resulting in the displacement of the backlight film and causing defects.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] As an improved manner of the utility model, the second limiting member includes a plurality of diaphragm ear plates, and the plurality of diaphragm ear plates are fixedly connected to one side of the backlight diaphragm.

[0009] As an improved manner of the present invention, the second limiting member further comprises a plurality of diaphragm limiting holes, and the plurality of diaphragm limiting holes are respectively opened on a plurality of diaphragm ear plates.

[0010] As an improvement of the utility model, the bottoms of several of the diaphragm limiting holes are provided with chamfers.

[0011] As an improvement of the utility model, the first limiting member includes a plurality of light guide plate ear plates, the plurality of light guide plate ear plates are fixedly connected to one side of the light guide plate body, and the positions of the plurality of light guide plate ear plates correspond to the positions of the plurality of diaphragm ear plates respectively.

[0012] As an improvement of the utility model, the first limiting member also includes a plurality of first convex strips, which are respectively fixedly mounted on the tops of a plurality of light guide plate ear plates, and the outer surfaces of the plurality of first convex strips are respectively plugged into the inner walls of a plurality of diaphragm limiting holes.

[0014] As an improvement of the present invention, a chamfer is provided on the top of the second boss to cooperate with the chamfer at the bottom of the diaphragm limiting hole to achieve guidance during insertion.

[0015] As an improved manner of the utility model, an elastic member is installed in the groove, and the elastic member is used to achieve expansion of the two ends of the top of the second boss.

[0016] As an improved manner of the utility model, a side of the light guide plate body away from the backlight film is connected to a backlight frame.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem in the prior art that the shaking of the module easily causes the movement of the film material and the displacement of the backlight film, causing defects, the present application arranges a first limiter on the light guide plate body and a second limiter on the backlight film. The second limiter and the first limiter are interconnected to achieve the limitation of the backlight film, thereby achieving stable fixation of the backlight film, effectively preventing the movement and displacement of the backlight film, and improving the stability of the module. Since this design improves the stability of the module, it reduces the number of defective products caused by the displacement of the backlight film and reduces the cost of subsequent rework.
