[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1: As Figure 1 -Figure 4 As shown in the figure, the utility model provides a light-leakage-proof liquid crystal display panel, which includes a circuit board 1, an outer frame 3 and a board body 4. The board body 4 is fixedly installed inside the outer frame 3. The outer frame 3 is fixedly connected to one side of the circuit board 1. The board body 4 is electrically connected to the circuit board 1. A plurality of groups of side grooves 31 are opened on the four sides of the outer frame 3. A side blocking mechanism 2 is arranged on the inner side wall of the side groove 31. The side blocking mechanism 2 includes a side strip 21, a limiting component and a side block 22. A groove 29 is opened on one side of the side strip 21. The limiting component pushes the groove 29 to fit the edge of the board body 4. The limiting component includes an inner block 23, a coupling shaft 25, a disc block 27 and a short rod 28. A raceway groove 24 and a through groove 26 are respectively opened in the middle of the inner block 23. The raceway groove 24 and the through groove 26 penetrate vertically. The coupling shaft 25 is fixedly connected to the eccentric position in the middle of the disc block 27. The coupling shaft 25 is located on the inner wall of the raceway groove 24. The short rod 28 is fixedly connected to the outside of the disc block 27. The disc block 27 is located inside the through groove 26.

[0022] The specific settings and functions of this embodiment are described below: By applying UV glue on the largest inner wall of the outer frame 3 and fitting the board body 4 into the outer frame 3, the four side strips 21 are respectively located between the edge of the board body 4 and the side wall of the outer frame 3, as Figure 4 shown. With the help of a tool, the short rod 28 is pushed outward. The short rod 28 drives the disc block 27 and the coupling shaft 25 to rotate counterclockwise. Since the coupling shaft 25 is at the eccentric position of the disc block 27, the edge of the disc block 27 that is farthest from the coupling shaft 25 pushes the side strip 21. The groove 29 on one side of the side strip 21 approaches the edge of the board body 4, as Figure 3 shown. The board body 4 is fitted in the groove 29, and the edge of the board body 4 is wrapped with the UV glue to ensure strict encapsulation. The side blocking mechanisms 2 on the remaining sides of the outer frame 3 are processed in the same way, thereby eliminating the gap between the board body 4 and the outer frame 3, improving the tightness during encapsulation, and avoiding light leakage.

[0023] Embodiment 2: As Figure 1 - Figure 4 shown, two side blocks 22 are parallel and attached to both sides of the inner block 23. The coupling shaft 25 is respectively rotatably connected to the two side blocks 22. The side blocks 22 are fixedly connected to one side of the circuit board 1.

[0024] The effect achieved by the entire embodiment is that by the side blocks 22 being located on the periphery of the outer frame 3 and the side blocks 22 being fixed on the circuit board 1, the side blocks 22 around the outer frame 3 fit the outer frame 3, providing stable support, ensuring that the outer frame 3 will not easily deform, and effectively reducing the probability of light leakage.

[0025] The method of use and working principle of the device are as follows: multiple groups of edge blocking mechanisms 2 are evenly distributed around the outer frame 3, the built-in block 23 extends to the inside of the outer frame 3 through the edge groove 31, the edge strip 21 is located on the inner side wall of the outer frame 3, and the largest inner wall of the outer frame 3 is coated with UV glue, and the board body 4 is stuck to the outer frame 3 and inserted, and the four groups of edge strips 21 are respectively located between the edge of the board body 4 and the side wall of the outer frame 3, and the short rod 28 is pushed outward with the help of a tool, and the short rod 28 drives the disk block 27 and the coupling 25 to rotate counterclockwise. Due to the eccentric position of the coupling 25 in the disk block 27, the edge of the disk block 27 farthest from the coupling 25 pushes the edge strip 21, and the groove 29 on one side of the edge strip 21 approaches the edge of the board body 4, wherein the board body 4 is embedded in the groove 29, and the edge of the board body 4 is wrapped with UV glue to ensure tight sealing, and the edge blocking mechanisms 2 on the remaining sides of the outer frame 3 are processed in the same way, thereby eliminating the gap between the board body 4 and the outer frame 3 to avoid light leakage.
