Description

Technical Field

[0001] This application relates to the field of screen display technology, and more particularly to a curved 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 displays, traditional techniques require molds to stamp the back panel and frame of the display, resulting in high costs and complex processes.

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.

[0035] 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.

[0036] 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.

[0037] like Figures 1 to 6 As shown in the figure, this application proposes a curved display screen including: a flexible back panel 1; a display module 2 connected to the flexible back panel 1; and a frame 3 including a plurality of connecting beams 301, which are sequentially connected to form a closed frame 3. Some of the connecting beams 301 are bent. The flexible back panel 1 is connected to the frame 3, and the frame 3 limits the position of the display module 2.

[0038] The curved display screen provided in this embodiment includes a flexible backplate 1, a display module 2, and a frame 3. The frame 3 includes multiple connecting beams 301, at least some of which are fully connected. Therefore, during the assembly of the curved display screen, the display module 2 can be first connected to the flexible backplate 1. The display module 2 is made of a film material and has a certain degree of flexibility. Then, the entire structure formed by the flexible backplate 1 and the display module 2 is connected to the frame 3. The shape of the frame 3 is adapted to the design requirements of the curved display screen. The flexible backplate 1 is fixed to the frame 3, and the flexible backplate 1 deforms according to the shape of the frame 3. Based on this, the curved display screen can be assembled. The curved display screen provided in this embodiment does not require a mold for the backplate, making processing simple and cost-effective.

[0039] The curved display screen provided in this application embodiment addresses the challenges of traditional curved screen manufacturing processes. Traditional curved screens require complex structural designs, necessitating bending around all four sides, increasing process complexity. Reinforcement of the back panel necessitates convex bulges, leading to high mold costs. Furthermore, the low material versatility prevents compatibility with multiple products simultaneously. High structural deformation requirements are also present, as twisting or deformation can negatively impact optical performance. In contrast, the curved display screen provided in this application embodiment only requires the fabrication of a complete connecting beam 301, combined with a flexible back panel 1, to complete the curved display screen fabrication. This simplifies the manufacturing process and reduces costs.

[0040] It is understandable that the flexible backplate 1 can be made of resin material, so that the flexible backplate 1 can deform with the connecting beam 301 while also taking into account a certain mechanical strength.

[0041] like Figures 1 to 6 As shown, in one feasible embodiment, a limiting protrusion 101 and a first fixing hole 102 are formed on the flexible back plate 1; a limiting recess 3011 and a second fixing hole 3012 are formed on the connecting beam 301, and fasteners pass through the first fixing hole 102 and the second fixing hole 3012. The limiting protrusion 101 is used to be disposed in the limiting recess 3011 so that the flexible back plate 1 is connected to the frame 3.

[0042] In this technical solution, the flexible back plate 1 and the connecting beam 301 are further provided. A limiting protrusion 101 and a first fixing hole 102 are formed on the flexible back plate 1, and a limiting recess 3011 and a second fixing hole 3012 are formed on the connecting beam 301. Based on this, the limiting protrusion 101 is arranged in the limiting recess 3011, and the connecting beam 301 can play a positioning role for the flexible back plate 1, reducing the probability of the flexible back plate 1 moving. The fasteners passing through the first fixing hole 102 and the second fixing hole 3012 can lock the flexible back plate 1 and the connecting beam 301, thereby fixing the flexible back plate 1.

[0043] like Figures 1 to 6 As shown, in one feasible embodiment, the connecting beam 301 includes: a beam body 3013, on which the limiting recess 3011 and the second fixing hole 3012 are formed; a limiting baffle 3014, which is connected to the side of the beam body 3013 away from the flexible back plate 1; when the flexible back plate 1 is connected to the frame 3, a limiting gap is formed between the flexible back plate 1 and the limiting baffle 3014, and the display module 2 is used to be disposed within the limiting gap.

[0044] In this technical solution, a style of connecting beam 301 is further provided. Connecting beam 301 may include beam body 3013 and limiting baffle 3014. Beam body 3013 serves to fix flexible back plate 1, while the setting of limiting baffle 3014 can limit the display module 2, making the positioning of display module 2 more reliable.

[0045] like Figures 1 to 6 As shown, in one feasible embodiment, the end of the connecting beam 301 is formed with a stepped surface 302 so that two adjacent connecting beams 301 can be inserted together. This arrangement, on the one hand, makes the structure of the frame 3 more stable and reduces the probability of unexpected deformation of the frame 3; on the other hand, it makes the two adjacent connecting beams 301 inserted more tightly, reducing gaps in the frame 3.

[0046] like Figures 1 to 6 As shown, in one feasible embodiment, the frame 3 includes multiple sets of oppositely arranged connecting beams 301, and some of the oppositely arranged connecting beams 301 are bent.

[0047] In this technical solution, the specific style of the connecting beam 301 is further provided. The frame 3 includes multiple sets of relatively arranged connecting beams 301. Among the multiple sets of relatively arranged connecting beams 301, some of the relatively arranged connecting beams 301 are bent, making the curved display screen more aesthetically pleasing.

[0048] like Figures 1 to 6 As shown, in one feasible embodiment, the display module 2 includes: a horizontal brightness enhancement film 201, a vertical brightness enhancement film 202, a diffusion film 203, a light guide plate 204, and a reflective film 205 arranged in sequence, wherein the reflective film 205 is disposed close to the flexible back plate 1.

[0049] In this technical solution, the structural composition of the display module 2 is further provided. The horizontal brightness enhancement film 201 can improve the brightness of light in the horizontal direction, the vertical brightness enhancement film 202 can improve the brightness of light in the vertical direction, the diffusion film 203 can diffuse the light into a surface, the light guide plate 204 can evenly emit the light of the LED, and the reflective film 205 can reflect the light of the LED onto the light guide plate 204.

[0050] The curved display screen provided in this application embodiment can be applied to 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, backlight technology will continue to be optimized to support higher performance display requirements.
