Example

[0023] In the specific implementation process, Figure 1-5 As shown, a liquid crystal screen splicing structure includes a back plate 1, a middle frame 2 and a front frame 3, a fixing frame 4 is provided on one side of the back plate 1, an LED light group 5 is provided on one side of the inner wall of the back plate 1, a diffusion plate 6 is provided on the side of the LED light group 5 away from the inner wall of the back plate 1, one side of the diffusion plate 6 is in contact with the side of the back plate 1 away from the fixing frame 4, a brightness enhancement film 7 is provided on the side of the diffusion plate 6 away from the back plate 1, the middle frame 2 is sleeved on the surface of the back plate 1, one side of the inner wall of the middle frame 2 is in contact with the side of the brightness enhancement film 7 away from the diffusion plate 6, and one side of the middle frame 2 is close to the fixing frame 4. One side of the back plate 1 is fixedly connected, and the front frame 3 is sleeved on the outer surface of the middle frame 2. The front frame 3 is connected to the side of the fixing frame 4 close to the back plate 1 through multiple bolts. A screen glass 8 is fixed inside the front frame 3. The weight of the back plate 1, the diffusion plate 6 and the brightness enhancement film 7 is borne by the middle frame 2, so that the front frame 3 is only used to fix the screen glass 8. Therefore, the thickness of the front frame 3 can be reduced to a certain extent. The light emitted by the LED lamp group 5 will be diffused by the diffusion plate 6, and the brightness will be increased by the brightness enhancement film 7, so that the light can cover the entire screen glass 8.

[0024] The front frame 3 includes an ultra-narrow frame 9 and a lower frame 10. The three sides of the inner wall of the ultra-narrow frame 9 are respectively fixedly connected to the top and both sides of the screen glass 8. The two ends of the bottom of the ultra-narrow frame 9 are respectively fixedly connected to the two ends of the top of the lower frame 10. The top of the lower frame 10 is fixedly connected to the bottom of the screen glass 8. The distance between the inner wall and the outer surface of the ultra-narrow frame 9 is less than or equal to 0.9 mm. When splicing, the physical seam will be less than or equal to 1.8 mm.

[0025] The screen glass 8 has a size of 75 inches. A back cover 11 for protecting electronic components is provided on the side of the back panel 1 close to the fixing frame 4. A power board, a logic board, and a driver board are provided in the back cover 11. They are electrically connected to each other and connected to the LED light group 5 through wires to control the LED light group 5 to emit light, thereby converging images. Handles 12 are provided on both sides of the inner wall of the fixing frame 4 for convenient placement of the fixing frame 4. A pin 13 for lifting the diffusion plate 6 is provided between the back panel 1 and the diffusion plate 6 to support the diffusion plate 6 and prevent the diffusion plate 6 from sticking to the LED light group 5. Example

[0026] Following the same structure as described in detail in Example 1, the difference from Example 1 is that the size of the screen glass 8 is 85 inches. Increasing the size of the screen glass 8 can reduce the number of joints of display screens of the same area, and present a more perfect effect.

[0027] The working principle provided by the utility model is as follows: by placing the back panel 1, the diffusion plate 6 and the brightness enhancement film 7 in the middle frame 2, one side of the middle frame 2 is fixed on the surface of the fixing frame 4, and the middle frame 2 can play a mobile supporting role for the back panel 1, the diffusion plate 6 and the brightness enhancement film 7, and then the ultra-narrow frame 9 and the lower frame 10 are attached to the surface of the middle frame 2, so that the screen glass 8 between the ultra-narrow frame 9 and the lower frame 10 is on the side of the brightness enhancement film 7 away from the diffusion plate 6, the size of the screen glass 8 is larger than the size of the back panel 1, and the light emitted by the LED lamp group 5 arranged on one side of the back panel 1 will be diffused by the diffusion plate 6, and the brightness will be increased by the brightness enhancement film 7, so that the light can cover the entire screen glass 8. Since the ultra-narrow frame 9 is only used to fix the screen glass 8, the distance between the inner wall and the outer wall of the ultra-narrow frame 9 can be reduced to less than or equal to 0.9 mm. When two such display screens are spliced, the physical seam will be less than or equal to 1.8 mm.
