[0055] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0056] This embodiment provides a solution that can reduce the risks of the above-mentioned problems. The solution provided in this embodiment will be described in detail below.

[0057] Please refer to Figure 1 , Figure 1 Example: A schematic structural diagram of a display module provided in this embodiment. In this embodiment, the display module may include a first support layer 100, at least two display panels 200 and a first adhesive layer 300.

[0058] At least two display panels 200 may be located on one side of the first support layer 100.

[0059] In this embodiment, at least two display panels 200 are spliced ​​together. The at least two display panels 200 can be identical display panels 200 or different display panels 200.

[0060] The first adhesive layer 300 may be located between two adjacent display panels 200. At least a portion of the first adhesive layer 300 extends to the side of the two display panels 200 away from the first support layer 100 to form a first convex lens 310. The first convex lens may cover the gap between the two adjacent display panels 200 and the edge of the two display panels 200 near the gap. The first convex lens 310 protrudes in a direction away from the first support layer 100.

[0061] In this embodiment, the display panel 200 can be pressed along the direction close to the first support layer 100, so that the first adhesive layer 300 can extend through the splicing gap between two adjacent display panels 200 to the side of the display panel 200 away from the first support layer 100, and form a first convex lens 310 covering the edges of the two adjacent display panels 200 and the splicing gap.

[0062] When two display panels 200 are spliced ​​together, a first convex lens 310 can be formed only at the splicing seam between the two display panels 200. Please refer to... Figure 2 When multiple display panels 200 are spliced ​​together, multiple first convex lenses 310 can be formed at the splicing gaps of the multiple display panels 200.

[0063] In the above design, by forming a first convex lens 310 on the side of the display panel 200 away from the first support layer 100 to cover the edges of two adjacent display panels 200 and the splicing gap, the light emission angle of the display panel 200 can be improved, visually eliminating the gap between the display panels 200 and improving the display effect.

[0064] In one possible implementation, please refer to Figure 3The display module may further include a second adhesive layer 400 located on the side of the display panel 200 away from the first support layer 100 and a second support layer 500 located on the side of the second adhesive layer 400 away from the display panel 200. The refractive index of the second adhesive layer 400 may be less than the refractive index of the first adhesive layer 300.

[0065] In this embodiment, the orthographic projection of the second adhesive layer 400 on the first support layer 100 can completely overlap with the orthographic projection of the display panel 200 on the first support layer 100, and the orthographic projection of the second adhesive layer 400 on the first support layer 100 can completely cover the orthographic projection of the first convex lens 310 on the first support layer 100. The orthographic projection of the second support layer 500 on the first support layer 100 can completely cover the orthographic projection of the second adhesive layer 400 on the first support layer 100.

[0066] Please refer to Figure 4 When the display panel 200 emits light from a direction away from the first support layer 100, the materials of the first adhesive layer 300 and the second adhesive layer 400 can be different, and the refractive index of the second adhesive layer 400 can be less than that of the first adhesive layer 300. In this way, it can be ensured that the light emitted by the display panel 200 is refracted at the junction of the first convex lens 310 and the second adhesive layer 400, improving the light emission angle at the splicing seam of the display panel 200, so that the first convex lens 310 can focus the light emitted by the display panel 200, thereby reducing the visual visibility of the splicing seam and improving the display effect.

[0067] In one possible implementation, please refer again. Figure 1 A third adhesive layer 600 may be provided between the first support layer 100 and the display panel 200.

[0068] In this embodiment, the materials of the first adhesive layer 300, the second adhesive layer 400, and the third adhesive layer 600 may all include optical adhesive.

[0069] In one possible implementation, the display panel 200 can be a transparent display panel 200, and the materials of the first support layer 100 and the second support layer 500 can include light-transmitting materials. In this way, double-sided light emission of the display module can be achieved, thereby improving the transparent display effect of the display module.

[0070] Preferably, the light transmittance of the first support layer 100 and the second support layer 500 can be greater than or equal to 95%.

[0071] For example, the materials of the first support layer 100 and the second support layer 500 can be anti-reflective (AR) glass.

[0072] In one possible implementation, when the display panel 200 emits light from both sides, the material of the third adhesive layer 600 is different from that of the first adhesive layer 300, and the third adhesive layer 600 does not directly contact the first adhesive layer 300.

[0073] Specifically, please refer to Figure 5 A second convex lens 700 may be provided on the side of the display panel 200 away from the second support layer 500. The second convex lens 700 can cover the gap between two adjacent display panels 200 and the edges of the two display panels 200 near the gap. The second convex lens 700 can protrude in a direction away from the second support layer 500. The refractive index of the third adhesive layer 600 can be less than the refractive index of the second convex lens 700.

[0074] In this embodiment, the display panel 200 can emit light simultaneously from both directions away from the first support layer 100 and away from the second support layer 500. The two light-emitting surfaces of the display panel 200 are respectively provided with a first convex lens 310 and a second convex lens 700. The orthographic projection of the first convex lens 310 on the first support layer 100 can completely coincide with the orthographic projection of the second convex lens 700 on the first support layer 100.

[0075] Please refer to Figure 6 When the display panel 200 emits light from a direction away from the first support layer 100, the refractive index of the second adhesive layer 400 can be less than the refractive index of the first adhesive layer 300. This ensures that the light emitted by the display panel 200 is refracted at the junction of the first convex lens 310 and the second adhesive layer 400, allowing the first convex lens 310 to focus the light emitted by the display panel 200, thereby reducing the visual visibility of the splicing gap and improving the display effect. Similarly, when the display panel 200 emits light from a direction away from the second support layer 500, the refractive index of the third adhesive layer 600 can be less than the refractive index of the second convex lens 700. This ensures that the light emitted by the display panel 200 is refracted at the junction of the second convex lens 700 and the third adhesive layer 600, allowing the second convex lens 700 to focus the light emitted by the display panel 200, thereby reducing the visual visibility of the splicing gap and improving the display effect.

[0076] In one possible implementation, please refer to Figure 7When the display panel 200 emits light from both sides, at least a portion of the first adhesive layer 300 extends to the side of the two display panels 200 away from the first support layer 100 to form a first convex lens 310. At least another portion of the first adhesive layer 300 extends to the side of the two display panels 200 near the first support layer 100 to form a third convex lens 800. The third convex lens 800 can cover the gap between two adjacent display panels 200 and the edges of the two display panels 200 near the gap. The third convex lens 800 can protrude towards the first support layer 100. Furthermore, the refractive index of the third adhesive layer 600 can be less than the refractive index of the third convex lens 800.

[0077] In this embodiment, the display panel 200 can emit light simultaneously from both directions away from the first support layer 100 and away from the second support layer 500. The two light-emitting surfaces of the display panel 200 are respectively provided with a first convex lens 310 and a third convex lens 800. The orthographic projection of the first convex lens 310 on the first support layer 100 can completely coincide with the orthographic projection of the third convex lens 800 on the first support layer 100. Furthermore, the first convex lens 310, the third convex lens 800, and the first adhesive layer 300 are made of the same material and are interconnected.

[0078] In another possible implementation, please refer to Figure 8 When the display panel 200 emits light only from a direction away from the first support layer 100, the materials of the third adhesive layer 600 and the first adhesive layer 300 can be the same, and the third adhesive layer 600 and the first adhesive layer 300 are connected to each other.

[0079] In this embodiment, the first convex lens 310 can be provided only on the side of the display panel 200 away from the first support layer 100 to ensure that the light emitted by the display panel 200 is refracted at the junction of the first convex lens 310 and the second adhesive layer 400, so that the first convex lens 310 can focus the light emitted by the display panel 200. At this time, the material of the third adhesive layer 600 located between the display panel 200 and the first support layer 100 can be the same as the material of the first adhesive layer 300, and the third adhesive layer 600 and the first adhesive layer 300 can be connected to each other.

[0080] This embodiment also provides a method for manufacturing a display module; please refer to [link / reference]. Figure 9 The method for manufacturing a display module may include the following steps.

[0081] Step S110: Provide a first support layer 100.

[0082] In step S120, at least two display panels 200 are bonded together by a first adhesive layer 300 on one side of the first support layer 100, such that at least a portion of the first adhesive layer 300 is located between two adjacent display panels 200, and at least a portion of the first adhesive layer 300 extends beyond the display panels 200 to a side away from the first support layer 100, forming a first convex lens 310 that covers the edges of the two display panels 200 and protrudes in a direction away from the first support layer 100.

[0083] In this embodiment, at least two display panels 200 can be bonded together by a first adhesive layer 300. At least a portion of the first adhesive layer 300 can be located at the splicing gap between two adjacent display panels 200, and at least a portion can extend through the splicing gap between the display panels 200 to the side of the display panel 200 away from the first support layer 100, forming a first convex lens 310.

[0084] In one possible implementation, please refer to Figure 10 Step S120 may include the following sub-steps.

[0085] Step S121: An adhesive material layer 300 is provided on one side of the first support layer 100.

[0086] In this embodiment, an adhesive material can be applied to one side of the first support layer 100 to form an adhesive material layer 300.

[0087] In step S122, at least two display panels 200 are placed on the side of the adhesive material layer 300 away from the first support layer 100, and the display panels 200 are pressed toward the first support layer 100, so that at least a portion of the adhesive material layer 300 is located between two adjacent display panels 200, and at least a portion of the adhesive material layer 300 overflows from the display panels 200 to the side away from the first support layer 100, forming a first convex lens 310 that protrudes in the direction away from the first support layer 100. The first convex lens 310 covers the gap between two adjacent display panels 200 and the edges of the two display panels 200 near the gap.

[0088] In this embodiment, please refer to Figure 11The display panel 200 and the first support layer 100 can be bonded together by an adhesive material layer 300. During the bonding process, the display panel 200 can be squeezed towards the first support layer 100, so that the adhesive material layer 300 extends away from the first support layer 100 through the splicing gap of the display panel 200. This forms a first convex lens 310 on the surface of the display panel 200 away from the first support layer 100, thus enabling the display panel 200 to emit light from the direction away from the first support layer 100.

[0089] When the display panel 200 emits light only from a direction away from the first support layer 100, at least a portion of the adhesive material layer 300 located on the side of the first support layer 100 near the display panel 200 can form a third adhesive layer 600.

[0090] It should be noted that the volume of the adhesive material coated on one side of the first support layer 100 can be determined by the size of the display panel 200, and is not specifically limited here.

[0091] In one possible implementation, during the bonding process between the first support layer 100 and the display panel 200, the display panel 200 needs to be squeezed toward the first support layer 100, so that the first adhesive layer 300 extends through the splicing gap between the display panels 200 to the other side of the display panel 200, thereby forming a first convex lens 310 covering the edge of the display panel 200. Therefore, the first adhesive layer 300 is flowable, and the dynamic viscosity of the first adhesive layer 300 can be less than 5000 centipoise (CP).

[0092] In one possible implementation, please refer to Figure 12 After step S120, the method for manufacturing the display module may further include the following steps.

[0093] In step S210, a second adhesive layer 400 is formed on the side of the display panel 200 away from the first support layer 100.

[0094] In this embodiment, an adhesive material different from that of the first adhesive layer 300 can be applied to the side of the display panel 200 away from the first support layer 100 to form a second adhesive layer 400, which can completely cover the first convex lens 310.

[0095] In step S220, a second support layer 500 is formed on the side of the second adhesive layer 400 away from the display panel 200.

[0096] In this embodiment, the material of the second adhesive layer 400 is different from that of the first adhesive layer 300, and the second support layer 500 and the display panel 200 can be bonded together through the second adhesive layer 400.

[0097] In one possible implementation, when the display module emits light from both sides, a first convex lens 310 and a second convex lens 700 can be formed on the two light-emitting surfaces of the display panel 200, respectively.

[0098] Please refer to Figure 13 After step S220, the method for manufacturing the display module may further include the following steps.

[0099] Step S310: Remove the first support layer 100 and the adhesive material layer 300 located on the side of the display panel 200 away from the second support layer 500.

[0100] In this embodiment, please refer to Figure 14 After step S220, the first support layer 100 can be removed, and the adhesive material layer 300 on the side of the display panel 200 away from the second support layer 500 can be removed by a thinning process or an ashing process.

[0101] When removing the adhesive material layer 300, only the adhesive material layer 300 on the side of the display panel 200 away from the second support layer 500 needs to be removed; the adhesive material layer 300 located at the splicing seam of the display panel 200 does not need to be removed.

[0102] In step S320, a second convex lens 700 is formed on the side of the display panel 200 away from the second support layer 500, covering the edges of the two display panels 200 and protruding in a direction away from the second support layer 500.

[0103] In this embodiment, a second convex lens 700 can be formed on the side of the display panel 200 away from the second support layer 500 by dispensing, printing or etching. The second convex lens 700 covers the edges of two adjacent display panels 200 and protrudes in a direction away from the second support layer 500. The material of the second convex lens 700 can be different from the material of the first adhesive layer 300.

[0104] Step S330: A third adhesive layer 600 is provided on the side of the display panel 200 away from the second support layer 500.

[0105] In this embodiment, an adhesive material different from that of the second convex lens 700 can be applied to the side of the display panel 200 away from the second support layer 500 to form a third adhesive layer 600.

[0106] Step S340: A new first support layer 100 is provided on the side of the third adhesive layer 600 away from the display panel 200.

[0107] In this embodiment, a new first support layer 100 can be provided on the side of the third adhesive layer 600 away from the display panel 200, so that the new first support layer 100 can be bonded to the display panel 200 through the third adhesive layer 600.

[0108] This embodiment also provides a method for manufacturing a display module; please refer to [link / reference]. Figure 15 The method for manufacturing a display module may include the following steps.

[0109] Step S410: A first adhesive layer 300 is provided in the gap between the display panels 200 arranged on the same layer.

[0110] In step S420, the adjacent display panels 200 are driven to move in a direction that brings them closer to each other, and the first adhesive layer 300 is squeezed so that at least a portion of the first adhesive layer 300 overflows the gap to form a first convex lens 310 and a third convex lens 800. The first convex lens 310 and the third convex lens 800 are respectively located on opposite sides of the display panels 200. The first convex lens 310 and the third convex lens 800 respectively cover the gap between two adjacent display panels 200 and the edges of the two display panels 200 near the gap.

[0111] In this embodiment, when the display panel 200 emits light from both sides, a first adhesive layer 300 can be disposed in the gap between at least two display panels 200 disposed on the same layer, and adjacent display panels 200 are moved in a direction that brings them closer to each other, squeezing the first adhesive layer 300 between the display panels 200, so that at least a portion of the first adhesive layer 300 overflows from the gap between the display panels 200, thereby forming a first convex lens 310 and a third convex lens 800 disposed opposite to each other. The first convex lens 310 and the third convex lens 800 both cover the gap between two adjacent display panels 200 and the edges of the two display panels 200 near the gap.

[0112] This embodiment also provides an electronic device, which may include the display module provided in this embodiment or a display module manufactured by the above method. The electronic device may include devices with display functions such as monitors, video wall displays, mobile phones, tablets, laptops, and televisions.

[0113] In summary, the embodiments of this application provide a display module and its manufacturing method. By forming a first convex lens on the side of the display panel away from the first support layer, covering the edges of two adjacent display panels and the splicing gap, the light emission angle of the display panel can be improved, visually eliminating the gap between the display panels and improving the display effect.
