Embodiment 1

[0036] Embodiment 1: as figure 1 and figure 2 As shown, the embodiment of the present invention provides a light guide plate, including a light guide plate main body 10, the side of the light guide plate main body 10 is provided with a protruding portion 1 protruding outward, and the light guide plate main body 10 is also provided with a The protrusion 1 is elastically deformed to position and fix the escape groove 2 of the light guide plate main body 10 .

[0037] The light guide plate itself is provided with a raised portion 1 and an escape groove 2 for positioning and fixing the light guide plate. The raised portion 1 cooperates with the avoidance groove 2 to make the raised portion 1 elastically deform to realize the positioning and fixing of the light guide plate. The light guide plate is fixed by means of the method, the light guide plate will not shake, and the stability of the light guide plate is enhanced, which is of great help to improve the frictional highlights ...

Embodiment 2

[0047] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the guide structure is formed by the outer surface of the raised portion 1 , and the outer surface includes a first The connecting surface 12 and the inclined surface 13 connected with the first connecting surface 12 . Such as image 3 and Figure 4 shown.

[0048] Such as Figure 4 As shown, the inclined surface 13 is formed by inclining the bottom of the first connecting surface 12 inwardly to reduce the resistance when the light guide plate is assembled, and the inclined angle of the inclined surface 13 can be set according to actual needs.

[0049] The first connection surface 12 is a planar structure, which enhances the stability of the light guide plate. When in use, the setting of the inclined surface 13 plays a guiding role in guiding the movement of the raised portion 1 along a predetermined direction. The raised portion 1 Part 1 is elastically deformed under force to realize the ...

Embodiment 3

[0051]Embodiment 3: The difference between this embodiment and Embodiment 1 is that the guide structure is formed by the outer surface 11 of the raised portion 1, and the outer surface 11 of the raised portion 1 is an arc surface, such as Figure 5 and Figure 6 shown.

[0052] Such as Figure 6 As shown, the outer arc surface of the outer surface 11, that is, the outwardly protruding curved surface structure, the smooth curved surface structure reduces the resistance when the light guide plate is assembled, and plays a role in guiding the protrusion 1 to move in a predetermined direction. The guiding function is beneficial to the positioning and fixing of the light guide plate.

[0053] The protruding part 1 is elastically deformed under force to realize the positioning and fixing of the light guide plate. By fixing the light guide plate in this way, the light guide plate will not shake, and the stability of fixing the light guide plate is enhanced.

[0054] In this embodi...

Abstract

A light guide plate is provided, including a body. A protruding portion that protrudes outwardly is provided on a lateral surface of the body, and the body is further provided with a slot. The slot is capable of enabling the protruding portion to be deformed elastically to position and fix the body. A backlight source and a display device are further provided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal product production, in particular to a light guide plate, a backlight source and a display device. Background technique [0002] At present, there are the following ways of fixing the light guide plate: [0003] 1. The clamping parts on the light guide plate and the clamping parts on the back plate are engaged together. This method is simple to assemble, but the light guide plate will shake in the product, the structural stability is poor, and friction is easy to occur Highlights; [0004] 2. Set a buffer between the light guide plate and the back plate, and fix the light guide plate in this way, the light guide plate will not shake, the product quality is better, but the buffer is added, the assembly is poor, labor costs and material costs very high. Contents of the invention [0005] In order to solve the above technical problems, the present invention provides a light guide plate, a...
