[0001] This application relates to the field of screen display technology, and more particularly to a curved backlight display screen. Background Technology
[0002] Backlighting technology provides the necessary light source for LCD screens, enabling images to be visible in dark environments. Since liquid crystals themselves do not emit light, the display function requires the synergy between the light source and the liquid crystal. With the trend towards thinner and lighter devices, backlight modules need to be further reduced in size while maintaining uniformity. Higher contrast and a wider color gamut are achieved through local dimming and color management technologies. In the manufacturing process of curved backlit displays, traditional techniques require molds to stamp the back panel and frame of the display, resulting in high costs and complex processes.

[0032] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.
[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.
[0034] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0035] like Figures 1 to 6 As shown in the figure, this application embodiment proposes a curved backlight display screen, including: a back plate 1, the back plate 1 being curved; an upper iron frame 2, the side wall of the upper iron frame 2 having a plurality of first grooves 201, so that when the upper iron frame 2 is mounted on the back plate 1, the side wall of the upper iron frame 2 can deform with the shape of the back plate 1; and a display module 3, the display module 3 being disposed between the upper iron frame 2 and the back plate 1.
[0036] The curved backlight display provided in this embodiment includes a back plate 1, an upper frame 2, and a display module 3. The back plate 1 is curved, and the upper frame 2 has multiple first grooves 201 on its sidewalls, allowing the sidewalls of the upper frame 2 to deform with the shape of the back plate 1 when it is mounted on the back plate 1. Based on this, during the manufacturing process of the curved backlight display, the back plate 1 can be stamped according to the design requirements of the curved backlight display to obtain the curved back plate 1. The upper frame 2 does not require a specially designed mold; instead, the first grooves 201 are formed on its sidewalls. In the assembly process of curved backlight display screen, the display module 3 can be first set on the back plate 1, and then the upper iron frame 2 with the first groove 201 is set on the back plate 1. Since multiple first grooves 201 are opened on the side wall of the upper iron frame 2, the multiple first grooves 201 can deform with the bending shape of the back plate 1, so that the upper iron frame 2 can deform with the shape of the back plate 1, thus completing the fixation of the display module 3. In this way, there is no need to prepare a mold for the upper iron frame 2 separately. The upper iron frame 2 is universal and can be used for back plates 1 of different specifications, which reduces production costs and simplifies the process steps.
[0037] It is understood that the curved backlight display provided in this application embodiment can adopt a side-lit light source. The upper iron frame 2 has an L-shaped structure. The optical film is placed in the back plate 1 in a certain order, buffered around the perimeter, and fixed in position. The upper iron frame 2 is fixed from the side and changes according to the curvature of the product (no secondary processing of curvature is required). After assembly, it can enter the testing stage.
[0038] Backlighting technology is widely used in devices such as smartphones, televisions, and computer monitors, and is the foundation of modern display technology. With the integration of technologies such as 5G and AI, backlighting technology will continue to be optimized to support the demand for higher performance displays.
[0039] like Figures 1 to 6 As shown, in one feasible embodiment, the curved backlight display screen further includes: a middle frame 4, wherein a plurality of second grooves 401 are provided on the side wall of the middle frame 4, so that when the middle frame 4 is mounted on the back plate 1, the side wall of the middle frame 4 can deform with the shape of the back plate 1; wherein, the display module 3 is disposed between the middle frame 4 and the back plate 1, and the upper iron frame 2 and the middle frame 4 are both connected to the back plate 1.
[0040] In this technical solution, the curved backlight display screen may also include a middle frame 4, on which a second groove 401 is formed. Based on the same principle as the upper iron frame 2, when the middle frame 4 is fixed to the back plate 1, it can also play the role of deforming with the back plate 1. The optical film material below the middle frame 4 supports the LCD above. The upper iron frame 2 can fix all the accessories below the upper iron frame 2. After locking the back plate 1 and the upper iron frame 2, they become a whole.
[0041] In one feasible implementation, the middle frame 4 is made of an elastic material, and based on this, the middle frame 4 also has a certain degree of flexibility, and the middle frame 4 can also deform according to the shape of the back plate 1.
[0042] In some examples, the middle frame 4 can be made of PA nylon material.
[0043] In one feasible implementation, the first groove 201 and the second groove 401 are arranged in an alternating manner. This arrangement makes the entire exterior surface of the curved backlight display screen enclosed, reducing the probability of dust and moisture entering and making the curved backlight display screen more aesthetically pleasing.
[0044] like Figures 1 to 6As shown, in one feasible embodiment, the first groove 201 and the second groove 401 have the same width; the plurality of first grooves 201 have the same opening width, and the gap width between two adjacent first grooves 201 is the same; the ratio of the total width of the plurality of first grooves 201 to the total length of the sidewall of the upper iron frame 2 is less than or equal to 1 / 10; the plurality of second grooves 401 have the same opening width, and the gap width between two adjacent second grooves 401 is the same; the ratio of the total width of the plurality of second grooves 401 to the total length of the sidewall of the middle frame 4 is less than or equal to 1 / 10. This configuration ensures that the upper iron frame 2 and the middle frame 4 can be bent, while also guaranteeing the mechanical strength of the upper iron frame 2 and the middle frame 4, thereby improving the service life of the curved backlight display screen.
[0045] like Figures 1 to 6 As shown, in one feasible embodiment, the display module 3 includes: a horizontal brightness enhancement film 301, a vertical brightness enhancement film 302, a diffusion film 303, a light guide plate 304, and a reflective film 305 arranged in sequence, wherein the reflective film 305 is disposed close to the back plate 1.
[0046] In this technical solution, the structural composition of the display module 3 is further provided. The horizontal brightness enhancement film 301 can improve the brightness of light in the horizontal direction, the vertical brightness enhancement film 302 can improve the brightness of light in the vertical direction, the diffusion film 303 can diffuse the light into a surface, the light guide plate 304 can evenly emit the light of the LED, and the reflective film 305 can reflect the light of the LED onto the light guide plate 304.
[0047] In the assembly process of the curved backlight display provided in this application embodiment, the horizontal brightness enhancement film 301, the vertical brightness enhancement film 302, the diffusion film 303, the light guide plate 304, and the reflective film 305 are first assembled onto the back plate 1. Then, the middle frame 4 is aligned with the back plate 1, pressed firmly, and locked in place using the side latches. Finally, the upper iron frame 2 is aligned with the middle frame 4 and assembled according to the curve corresponding to the back plate 1, and the four sides are locked with screws. This process yields a curved backlight display with the desired curved surface, replacing the traditional manufacturing method and reducing molds and processes.
