Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0036] With the rapid development of display technology, its size and application scenarios are constantly expanding. Limited by the size of various display modules themselves, splicing is used to achieve ultra-large-size displays, which has been applied to all aspects of life, such as outdoor advertising, stadiums, command halls, shopping malls and other application scenarios. In splicing display modules, adjacent display panels usually have areas that cannot be displayed in the splicing area, which is called splicing seam. The splicing seam will affect the display effect of the splicing display module.

[0037] Please see Figures 1 to 11 This invention provides a splicing display module 100, including at least two first display areas A and a splicing area B located between two adjacent first display areas A. The splicing display module 100 includes:

[0038] At least two display panels 200, each display panel 200 including a display portion 210 and a non-display portion 220 located around the display portion 210, the display portion 210 including a flat display sub-port 211 and a curved display sub-port 212 located around the flat display sub-port 211, the curved display sub-port 212 being located between the flat display sub-port 211 and the non-display portion 220, the curved display sub-port 212 corresponding to the splicing area B, and the flat display sub-port 211 corresponding to the first display area A;

[0039] Optical component 300, corresponding to the curved display sub-part 212, is located on the light-emitting side of the curved display sub-part 212, and deflects the light emitted by the curved display sub-part 212 to emit it in a direction away from the first display area A corresponding to the display panel 200.

[0040] This invention provides an optical component on the light-emitting side of the curved display sub-unit to deflect the light emitted from the curved display sub-unit and direct it toward the first display area away from the corresponding display panel. This allows the display light from the curved display sub-unit to be directed toward the splicing seam of the corresponding splicing area, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module.

[0041] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0042] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 The splicing display module 100 includes at least two first display areas A and a splicing area B located between two adjacent first display areas A. The splicing display module 100 includes at least two display panels 200 and optical components 300. Each display panel 200 includes a display portion 210 and a non-display portion 220 located around the display portion 210. The display portion 210 includes a planar display sub-port 211 and a curved display sub-port 212 located around the planar display sub-port 211. The surface display sub-part 212 is located between the flat display sub-part 211 and the non-display part 220. The curved display sub-part 212 corresponds to the splicing area B, and the flat display sub-part 211 corresponds to the first display area A. The optical component 300 corresponds to the curved display sub-part 212 and is located on the light-emitting side of the curved display sub-part 212, so that the light emitted by the curved display sub-part 212 is deflected and emitted in a direction away from the first display area A corresponding to the display panel 200.

[0043] The light emitted by the curved display sub-part 212 does not easily reach the centerline corresponding to the splicing area B. Therefore, the distance between the point on the cover layer 910 of the splicing display module 100 where the display light from the curved display sub-part 212 reaches and the point on the cover layer 910 of the splicing display module 100 corresponding to the centerline of the splicing area B, i.e., the distance corresponding to the splicing seam, please refer to [link / reference needed]. Figure 2 , Figure 3 The centerline of the splicing area B is indicated by the label "960". Using the optical component 300, the light emitted by the curved display sub-unit 212 is deflected from the direction corresponding to the first display area A to the corresponding splicing area B, so that the display light of the curved display sub-unit 212 is closer to the centerline of the splicing area B, so that the splicing area B has a display effect, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0044] In some embodiments, the curved display sub-parts 212 are all curved surfaces in any state of the display panel 200, as will be described here.

[0045] In some embodiments, please refer to Figure 2 , Figure 3 The optical component 300 includes a refractive functional layer 400 located on the curved display sub-part 212. The refractive functional layer 400 includes at least a first optical layer 401 and a second optical layer 402. The first optical layer 401 is located on the light-emitting side of the curved display sub-part 212, and the second optical layer 402 is located on the side of the first optical layer 401 away from the curved display sub-part 212. The first optical layer 401 includes a first sub-layer 410 close to the corresponding flat display sub-part 211, and the second optical layer 402 includes a third sub-layer 430 close to the corresponding flat display sub-part 211. The refractive index of the first sub-layer 410 is greater than the refractive index of the corresponding position of the third sub-layer 430.

[0046] The optical component 300 may include the refractive functional layer 400. Taking the refractive functional layer 400 as including the first optical layer 401 and the second optical layer 402 as an example, the second optical layer 402 is closer to the human eye. The refractive index of the first sub-layer 410 is greater than the refractive index of the corresponding position of the third sub-layer 430. As a result, when the light emitted by the curved display sub-part 212 passes through the first sub-layer 410 and the third sub-layer 430, the light is deflected from the direction corresponding to the first display area A to the corresponding splicing area B. This makes the display light of the curved display sub-part 212 closer to the center line corresponding to the splicing area B, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0047] In this paper, the comparison of refractive indices can be understood as a comparison of the refractive indices of the corresponding contact film support. When light passes through film layers with different refractive indices, it will be deflected. The path of light from a low refractive index to a high refractive index film layer can be represented by the light being deflected towards the normal direction of the film layer with the higher refractive index. Here, the normal of the film layer with the higher refractive index represents the perpendicular line to the contact surface of the two film layers; and vice versa.

[0048] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 The first optical layer 401 includes a first sub-layer 410 near the corresponding planar display sub-part 211 and a second sub-layer 420 near the non-display part 220; the second optical layer 402 includes a third sub-layer 430 near the corresponding planar display sub-part 211 and a fourth sub-layer 440 near the non-display part 220; wherein the refractive index of the second sub-layer 420 is less than the refractive index of the corresponding position of the fourth sub-layer 440.

[0049] The portion of the curved display sub-section 212 that can be efficiently utilized is the portion of the display section 210 that is close to the flat display sub-section 211. Therefore, by utilizing the refractive index difference between the first sub-layer 410 and the third sub-layer 430, the portion of the curved display sub-section 210 that can be efficiently utilized is optimized, so that the display light of the curved display sub-section 212 that is close to the flat display sub-section 211 is closer to the center line of the corresponding splicing area B, thereby improving the display effect. The portion of the curved display sub-section 212 that is far from the flat display sub-section 211 is made to utilize the refractive index difference between the second sub-layer 420 and the fourth sub-layer 440, so that the light of the curved display sub-section 212 that is far from the flat display sub-section 211 is emitted more perpendicularly, increasing the display brightness of the splicing area B, thereby reducing the shadow of the splicing seam, thereby reducing the size of the splicing seam, and improving the display effect of the splicing display module 100.

[0050] In some embodiments, please refer to Figure 2 , Figure 3 The first optical layer 401 includes a first sub-layer 410 near the corresponding planar display sub-part 211, and the second optical layer 402 includes a third sub-layer 430 near the corresponding planar display sub-part 211; wherein, in the direction from the planar display sub-part 211 to the non-display part 220, the difference between the refractive index of the first sub-layer 410 near the third sub-layer 430 and the refractive index of the third sub-layer 430 near the first sub-layer 410 gradually decreases.

[0051] The display light rays on the side of the curved display sub-part 212 closest to the flat display sub-part 211 can be deflected more towards the centerline of the splicing area B. However, if the display light rays on the side of the curved display sub-part 212 furthest from the flat display sub-part 211 are deflected too much towards the centerline of the splicing area B, the display light rays will not be able to escape, resulting in a decrease in the utilization rate of the display light rays. Therefore, in the direction from the flat display sub-part 211 to the non-display part 220, the difference between the refractive index of the first sub-layer 410 and the refractive index of the corresponding position of the third sub-layer 430 gradually decreases, further balancing the relationship between the display light rays of the curved display sub-part 212 closest to and furthest from the flat display sub-part 211 and the splicing seam of the splicing area B, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0052] In some embodiments, please refer to Figure 4 The first sub-layer 410 and the second sub-layer 420 each occupy half of the area of ​​the first optical layer 401, and the third sub-layer 430 and the fourth sub-layer 440 each occupy half of the area of ​​the second optical layer 402.

[0053] That is, when the cross-sectional view of the curved display sub-part 212 is a quarter circle, the cross-sectional view of the first sub-layer 410 is an eighth circle, and the cross-sectional view of the second sub-layer 420 is an eighth circle, so as to balance the relationship between the display light of the curved display sub-part 212 near the flat display sub-part 211 and away from the flat display sub-part 211 and the splicing seam of the splicing area B, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0054] In some embodiments, the refractive functional layer 400 includes multiple optical layers, and along the light emission direction of the curved display sub-part 212, the refractive index of the multiple optical layers of the refractive functional layer 400 first decreases and then increases.

[0055] In the refractive functional layer 400, the propagation path of the display light of the curved display sub-part 212 is first refracted in the horizontal direction and then in the vertical direction. Compared with the splicing display module 100, the horizontal deflection of light can reduce the splicing seam size of the splicing area B, and the vertical deflection of light can increase the display brightness of the splicing area B. This balances the relationship between the splicing seam size and the display brightness of the splicing area B, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0056] In some embodiments, the refractive functional layer 400 can be directly attached or deposited by vapor deposition, and no specific limitation is made here.

[0057] In some embodiments, the display panel 200 further includes a supplementary light display sub-section located between the non-display portion 220 and the curved display sub-section 212.

[0058] The supplementary lighting display sub-unit can emit white light to increase the display brightness of the splicing area B, thereby reducing the shadow of the splicing seam, reducing the size of the splicing seam, and improving the display effect of the splicing display module 100.

[0059] In some embodiments, please refer to Figure 2 , Figure 5 , Figure 7 A gap 30 is provided between the curved display sub-parts 212 of two adjacent display panels 200 and between the non-display parts 220 of two adjacent display panels 200, and a filling part 500 is provided in the gap 30.

[0060] The filling part 500 corresponds to the splicing area B. Since the curved display sub-part 212 is arc-shaped, there is a step gap 30 between two adjacent display panels 200. The filling part 500 is used to flatten the step gap so that there are flatter forming conditions when forming the cover layer 910, thereby improving the overall film layer flatness of the splicing display module 100.

[0061] In some embodiments, please refer to Figure 5 The filling portion 500 includes a matrix 510 and a plurality of scattering particles 520 dispersed within the matrix 510.

[0062] The matrix 510 can be an organic material, and the scattering particles 520 can be high-refractive-index nanoparticles. The scattering particles 520 can improve the light uniformity of the curved display sub-part 212 in the splicing area B, thereby reducing the splicing seam, reducing the shadow of the splicing seam, reducing the size of the splicing seam, and improving the display effect of the splicing display module 100.

[0063] In some embodiments, the matrix 510 may be a variety of free radical polymerizable monomers, oligomers, polymers, and mixtures thereof, and the refractive index of the film can be controlled by adjusting the concentration and / or type of the matrix components.

[0064] In some embodiments, the scattering particles 520 may be any one or a combination of the following: zirconium oxide (ZrO2), titanium dioxide (TiO2), antimony oxide, aluminum oxide, tin oxide, etc., or may be mixed metal oxides. The refractive index of the material is between 1.6 and 3.0. For example, titanium dioxide (TiO2) particles have a very high refractive index of 2.6 to 2.9.

[0065] In some embodiments, the refractive index of the film can be controlled by adjusting the concentration of scattering particles and the type of metal oxide.

[0066] In some embodiments, please refer to Figure 2 , Figure 7 The splicing display module 100 also includes a support block 600 for fixing two adjacent display panels 200. The support block 600 includes a support part 610 connected to the non-display part 220 of the display panel 200 and a supplementary part 620 disposed on the support part 610 and inserted into the gap 30.

[0067] The support block 600 is used to fix two adjacent display panels 200, and also to support the material of the filling portion 500 when the filling portion 500 is formed. The width of the supplementary portion 620 of the support block 600 near the filling portion 500 corresponds to the distance between two adjacent curved display sub-parts 212 of the two adjacent display panels 200. The width of the supplementary portion 620 of the support block 600 near the filling portion 500 is represented by the label "L". When assembling the splicing display module 100, the assembly gap 30 of the display panels 200 of the splicing display module 100 can be adjusted by adjusting the size of L.

[0068] In some embodiments, the width L of the supplementary portion 620 on the side near the filling portion 500 is 0 mm to 10 mm.

[0069] In some embodiments, please refer to Figure 2 , Figure 7 The gap 30 includes a first sub-gap 31 corresponding to the curved display sub-part 212 and a second sub-gap 32 corresponding to the non-display part 220; wherein the filling part 500 fills the first sub-gap 31 and the supplementary part 620 of the support block 600 fills the second sub-gap 32.

[0070] The supplementary part 620 fills the second sub-gap 32 and carries the filling part 500 to fill the first sub-gap 31, ensuring that the surface of the filling part 500 away from the curved display sub-part 212 is flat, which facilitates the setting of the upper film layer, such as the cover plate layer 910.

[0071] In some embodiments, please refer to Figure 2 , Figure 7 In the light-emitting direction away from the planar display sub-section 211, the width of the first sub-gap 31 gradually decreases; please refer to Figure 7 In the light-emitting direction away from the planar display sub-section 211, the width of the second sub-gap 32 gradually increases, or, please refer to... Figure 2The width of the second sub-gap 32 is equal.

[0072] In the light-emitting direction away from the planar display sub-part 211, the width of the first sub-gap 31 gradually decreases, and the curved display sub-part 212 is used to reduce the seam. In the light-emitting direction away from the planar display sub-part 211, the width of the second sub-gap 32 gradually increases, so as to bend the non-display part 220 to the back of the splicing display module 100. In the light-emitting direction away from the planar display sub-part 211, the width of the second sub-gap 32 is equal, so as to save the process of bending the non-display part 220.

[0073] In some embodiments, the curved display sub-part 212 is a quarter circle with a minimum bending radius of 0.3 mm. The width of the first sub-gap 31 on the side furthest from the support block is related to the bending radius of the curved display sub-part 212 and the width L of the supplementary part 620 on the side close to the filling part 500. Therefore, the minimum width of the first sub-gap 31 on the side furthest from the support block is 0.6 mm.

[0074] In some embodiments, please refer to Figure 2 The splicing display module 100 also includes a back plate 940, an adhesive layer, and a support plate 950 disposed on the side of the display panel 200 away from the light emission side.

[0075] In some embodiments, the minimum total thickness of the display panel 200, back plate 940, adhesive layer, and support plate 950 is 0.4 mm, therefore the minimum width of the support portion 610 on the side near the supplementary portion 620 is 0.8 mm.

[0076] In some embodiments, please refer to Figure 8 The splicing display module 100 further includes at least one light-concentrating layer 700 located on the side of the filling portion 500 away from the display panel 200; wherein, the refractive index of the light-concentrating layer 700 closest to the filling portion 500 is greater than the refractive index of the filling portion 500, and in the light-emitting direction, among two adjacent light-concentrating layers 700, the refractive index of the light-concentrating layer 700 closest to the filling portion 500 is less than the refractive index of the light-concentrating layer 700 away from the filling portion 500.

[0077] The light-concentrating layer 700 is used to focus the light, so that the light emitted by the curved display sub-part 212 toward the splicing area B is emitted more perpendicularly and converges at the center line of the splicing area B, where the center line of the splicing area B is indicated by the label "960". This increases the display light of the curved display sub-part 212, thereby increasing the display light of the splicing area B, increasing the display brightness of the splicing area B, thereby reducing the shadow of the splicing seam, thereby reducing the size of the splicing seam, and improving the display effect of the splicing display module 100.

[0078] In some embodiments, the difference between the refractive index of the light-concentrating layer 700 closest to the filling portion 500 and the refractive index of the filling portion 500 is greater than or equal to 0.4, so as to effectively increase the display brightness of the splicing area B, thereby reducing the shadow of the splicing seam, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0079] In some embodiments, when there are multiple light-concentrating layers 700, the refractive index difference between two adjacent light-concentrating layers 700 is greater than or equal to 0.2, so as to effectively increase the display brightness of the splicing area B, thereby reducing the shadow of the splicing seam, thereby reducing the size of the splicing seam and improving the display effect of the splicing display module 100.

[0080] In some embodiments, please refer to Figure 2 , Figure 6 , Figure 8 The splicing display module 100 further includes a cover layer 910, which covers the first display area A and the splicing area B.

[0081] After the splicing area B is filled with the filling part 500, the first display area A and the splicing area B are covered with the same cover plate layer 910 to ensure that the light-emitting surfaces of the two adjacent display panels 200 are on the same horizontal plane, thus ensuring the display effect.

[0082] In some embodiments, please refer to Figure 9 The optical component 300 is disposed on the light-emitting side of the curved display sub-part 212. The optical component 300 includes a plurality of optical microstructures 301, each of which is a protrusion 302 or a recess 303.
