[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] See also Figure 1-4 In the present embodiment, a display module structure capable of improving light uniformity includes a backlight panel 1 and a light source unit 2. A quick assembly mechanism is provided between the backlight panel 1 and the light source unit 2. The quick assembly mechanism includes a light source unit seat 3 fixedly mounted on the surface of the backlight panel 1, a spring 4 fixedly mounted on the surface of the light source unit seat 3, a card block 5 and a top block 6 fixedly mounted on the surface of the spring 4, a card slot 7 opened on the surface of the top block 6, a rectangular frame 8 sleeved on the outer surface of the spring 4, a card strip 9 fixedly mounted on the inner surface of the rectangular frame 8, a connecting seat 10 fixedly mounted on the surface of the light source unit 2, a rectangular groove 11 opened on the surface of the connecting seat 10, and a fixing groove 12 opened in the rectangular groove 11.

[0027] There are multiple light source unit seats 3, and multiple light source unit seats 3 are evenly distributed on the surface of the backlight panel 1. Each light source unit seat 3 and the light source unit 2 are independently controlled. By independently controlling the brightness of each light source unit 2, the luminous intensity of different areas on the display panel can be finely adjusted, thereby improving the luminous uniformity. There are two spring pieces 4. The card block 5 is fixedly installed on the opposite side surface of the two spring pieces 4. The card block 5 is adapted to the card slot 12, which is convenient for clamping the connecting seat 10 between the two spring pieces 4 and for the card block 5 to be clamped into the fixed slot 12. The top block 6 is fixedly installed on the opposite side surface of the two spring pieces 4. The card slot 7 is adapted to the card strip 9, which is convenient for clamping the card strip 9 into the card slot 7. One side surface of the top block 6 is an inclined surface, and the inclined surface of the top block 6 is close to the rectangular frame 8. By designing the top block 6 as an inclined surface, it is convenient for the card strip 9 to contact the top block 6. The external shape and size of the spring piece 4 are adapted to the internal shape and size of the rectangular groove 11, which is convenient for the spring piece 4 to be clamped into the rectangular groove 11.

[0028] It should be noted that the multiple light source units 2 can significantly improve the light emission uniformity of the display module, so that the display effect of the display device is significantly improved. At the same time, the independently controlled light source unit seat 3 design can achieve fine adjustment of different areas on the display panel, thereby improving the flexibility and accuracy of the adjustment.

[0029] The working principle of the above embodiment is:

[0030] When in use, the connecting seat 10 on the light source unit 2 is inserted between the two spring pieces 4, so that the spring piece 4 and the card block 5 are inserted into the rectangular groove 11 until the card block 5 is inserted into the fixed groove 12, and then the rectangular frame 8 is moved upward to make the card strip 9 insert into the card groove 7 along the inclined surface of the top block 6, thereby preventing the spring piece 4 from separating from the connecting seat 10, and then the light source unit 2 can be installed on the light source unit seat 3. When disassembling, you only need to move the rectangular frame 8 downward to separate the card strip 9 from the card groove 7, and then you can push the spring piece 4 to both sides, and then you can remove the light source unit 2 from the light source unit seat 3.
