[0003] Currently, the display screen and the support plate are spliced ​​together with optical transparent adhesive, but the physical seams are not treated in any way. The human eye will receive the light reflected from the seams, making the seams visually obvious and affecting the splicing appearance and display effect. At the same time, the splicing strength of adjacent display screens is also insufficient, resulting in low overall stability of the splicing screen. Summary of the Invention

[0006] According to one aspect of the present invention, the convex portion includes an outwardly convex arcuate surface toward the concave portion, and the concave portion has an inwardly concave arcuate surface toward the convex portion.

[0007] According to one aspect of the present invention, the convex arc surface and / or the concave arc surface are circular arcs.

[0008] According to one aspect of the present invention, the radius of the convex arc surface is R1, the radius of the concave arc surface is R2, and the thickness of the sub-panel is D; wherein, R2≥R1≥D / 2;

[0012] Preferably, the extension lengths of the plurality of sub-planes on the same side surface are equal;

[0013] Preferably, the included angle between two adjacent sub-planes is 150-155 degrees;

[0014] Preferably, the same side surface includes more than five sub-planes;

[0015] Preferably, the same side surface comprises an odd number of the sub-planes.

[0016] According to one aspect of the present invention, both the convex portion and the concave portion include the side surface, and a plurality of sub-planes of the convex portion and a plurality of sub-planes of the concave portion are provided in a one-to-one correspondence;

[0017] Preferably, the subplane extension length of the convex portion and the subplane extension length of the concave portion are equal;

[0018] Preferably, the included angle between adjacent sub-planes of the convex portion is equal to the included angle between adjacent sub-planes of the concave portion.

[0019] According to one aspect of the present invention, at least a portion of the protrusion is received in the recess;

[0020] Preferably, the protrusion abuts against the recess;

[0021] Preferably, the side surface of the protrusion and the side surface of the concave portion have the same shape and contour, and the protrusion and the concave portion are seamlessly joined.

[0022] According to one aspect of the present invention, the display panel includes a connection layer disposed on the substrate, and a plurality of sub-panels disposed on the side of the connection layer opposite to the substrate, and the plurality of sub-panels are connected to the substrate through the connection layer;

[0023] Preferably, the substrate includes a first light-transmitting plate and a second light-transmitting plate, and the connecting layer includes a first optical adhesive layer and a second optical adhesive layer. The first optical adhesive layer is disposed on the first light-transmitting plate and the second optical adhesive layer is disposed on the second light-transmitting plate.

[0026] This invention provides a display panel and a display device. By providing a protrusion on one of two adjacent sub-panels and a recess on the other, the two sub-panels are spliced ​​together using the interlocking fit of the protrusion and recess. Because of the protrusion and recess between the two adjacent sub-panels, light undergoes diffuse reflection at the splicing point, avoiding light concentration caused by total emission. This prevents the seam from being clearly visible at the splicing point. The structural fit of the protrusion and recess reduces the visual impact of the seam, thereby improving the overall display effect. Simultaneously, the interlocking fit of the protrusion and recess improves the connection stability between adjacent sub-panels, giving the screen better structural strength. While improving the display effect at the seam, it also ensures the overall strength of the spliced ​​screen. Attached Figure Description

[0038] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the invention; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0039] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the display panel and display device of the present invention. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0040] To better understand this invention, the following is combined with... Figures 1 to 5 The display panel and display device according to embodiments of the present invention will be described in detail.

[0041] Please see Figures 1 to 3This invention provides a display panel 100, including a substrate 10 and sub-panels 20. Multiple sub-panels 20 are arranged side by side on one side of the substrate 10. In two adjacent sub-panels 20, one includes a protrusion 21 facing the other, and the other includes a recess 22 corresponding to the protrusion 21. Two adjacent sub-panels 20 extend into the recess 22 through the protrusion 21 to form a splice.

[0042] Optionally, the display panel 100 proposed in this embodiment is a splicing screen structure, specifically, multiple sub-panels 20 are spliced ​​on the substrate 10 to form a whole screen. Each sub-panel 20 can emit light independently, such as using Mini LED display or Micro LED display. This application does not impose a special limit on the specific number of sub-panels 20, which needs to be determined according to the actual panel size.

[0043] In this embodiment, it is mainly considered that after multiple sub-panels 20 are spliced ​​together, seams are easily generated at the splicing position. When the seam is wide, it will have an adverse effect on the user's visual experience. The display at the seam position is not aesthetically pleasing, and the joint strength at this position also needs to be improved. Therefore, the novel display panel 100 structure in this application is proposed.

[0044] Specifically, when two adjacent sub-panels 20 are spliced ​​together, the specific structure of the sub-panel 20 can be improved. A protrusion 21 is provided at one sub-panel 20 and a recess 22 is provided at the other sub-panel 20. The size of the protrusion 21 is close to the size of the recess 22, so that the splicing of adjacent sub-panels 20 can be achieved through the mating and cooperation of the protrusion 21 and the recess 22.

[0045] Because the joint between the sub-panels 20 in the existing product structure is a flat surface, when light passes through the flat surface, total internal reflection is likely to occur at this location, making the seam at the joint particularly noticeable and causing a poor visual experience for users.

[0046] Therefore, in this embodiment, the splicing position of adjacent sub-panels 20 is set as a structure in which a concave portion 22 and a convex portion 21 meet. When light passes through this position, the light is diffusely reflected at the convex portion 21, scattering the light and preventing light concentration. Similarly, the light is also diffusely reflected at the concave portion 22. In other words, the light will not be concentrated and reflected at this splicing position, so the splicing position will not be visible, and ultimately there will be no obvious splicing, improving the viewing effect for users at the splicing position.

[0047] Meanwhile, compared with the prior art, the mating of the protrusion 21 and the concave portion 22 in this embodiment also improves the connection relationship between adjacent sub-panels 20. The concave-convex fit makes it easier to form a lock between adjacent sub-panels 20. Compared with the prior art which only uses optical adhesive for bonding, it has better structural stability and further improves the structural strength of the splicing between sub-panels 20.

[0048] In this embodiment, the protrusions 21 and recesses 22 provided on the sub-panel 20 can have various structural forms, and this application does not limit them. The mating structure of the protrusions 21 and recesses 22 can all form diffuse reflection of light. Any structure that uses the mating structure of protrusions and recesses to form a joint to reduce concentrated reflection of light is within the protection scope of this application.

[0049] This invention provides a display panel 100. By providing a protrusion 21 on one of two adjacent sub-panels 20 and a recess 22 on the other, the two adjacent sub-panels 20 are spliced ​​together using the interlocking fit of the protrusion 21 and the recess 22. Because of the protrusion 21 and the recess 22 between the two adjacent sub-panels 20, when light passes through the splicing point, diffuse reflection occurs at the protrusion 21 and the recess 22, thus avoiding light concentration caused by total emission. This makes the seam at the splicing point of the adjacent sub-panels 20 more noticeable. The structural fit of the protrusion 21 and the recess 22 reduces the visual impact at the seam, thereby improving the overall display effect. Simultaneously, the interlocking fit of the protrusion 21 and the recess 22 improves the connection stability between the adjacent sub-panels 20, giving the screen better structural strength. While improving the display effect at the seam, it also ensures the overall strength of the spliced ​​screen.

[0050] As an optional embodiment, please refer to Figure 2 and Figure 3 The protrusion 21 includes an outwardly convex arc surface 1 facing the concave portion 22, and the concave portion 22 has an inwardly concave arc surface 2 facing the protrusion 21.

[0051] Optionally, in this embodiment, an outwardly convex arc surface 1 is provided at the position of the protrusion 21, and the outwardly convex arc surface 1 protrudes towards the concave part 22, so as to form a docking with the concave part 22; similarly, an inwardly concave arc surface 2 is provided at the position of the concave part 22, and the opening of the inwardly concave arc surface 2 faces the protrusion 21, so as to accommodate the protrusion 21.

[0052] This application does not impose special limitations on the dimensions and structure of the convex arc surface 1 and the concave arc surface 2. They can be determined according to the actual structural splicing needs, such as forming a circular arc surface, an elliptical arc surface, or a multi-segment arc surface.

[0053] When light passes through the convex arc surface 1 and the concave arc surface 2, since the two arc surfaces are not flat, the reflection angle of light at different angles at the two arc surfaces is somewhat different. This causes the light to be reflected in all directions after passing through the two arc surfaces, achieving a diffuse reflection effect. As a result, no obvious seam will appear when the human eye observes the splicing position, improving the overall visual experience of the splicing screen.

[0054] Of course, the protrusions 21 and concave parts 22 on the sub-panel 20 may not have the outer convex arc surface 1 and the inner concave arc surface 2. For example, the protrusions 21 can be set as a raised structure and the concave parts 22 can be set as a groove structure that matches it. Although the above-mentioned arc surfaces are not formed, the mating position of the sub-panel 20 can form a stepped surface shape with concave and convex surfaces. The mating surface of this shape can also reflect light to different angle positions to form a diffuse reflection effect, reducing the user's perception of the seam position, thereby having a better display effect.

[0055] This invention provides a display panel 100. By providing an outwardly convex arc surface 1 to the convex portion 21 and an inwardly concave arc surface 2 to the concave portion 22, the arc surface structure can diffusely reflect light, while also forming a more regular and matched docking structure between the convex portion 21 and the concave portion 22. Moreover, the arc surface structure is also beneficial for the manufacturing process.

[0056] As an optional embodiment, please refer to Figure 2 and Figure 3 The convex arc surface 1 and / or the concave arc surface 2 are circular arcs.

[0057] Optionally, the convex arc surface 1 and the concave arc surface 2 can be specifically designed as arc-shaped structures. The arc shape can form a more complete and smooth reflection of light, so that it is reflected to different angle positions.

[0058] Optionally, for the arc-shaped structure, the convex arc surface 1 and the concave arc surface 2 can have various sizes. For example, the sizes of the two can be set to be the same or different. It should be noted that at this time, the concave part 22 needs to accommodate at least part of the convex part 21 to form a splicing relationship. The two can form an abutment or a gap. This application does not limit this.

[0059] This invention provides a display panel 100, which is made easier to process and form, and more regular and flat by setting the convex arc surface 1 and the concave arc surface 2 as arc-shaped structures. It is also easier to connect the convex part 21 and the concave part 22, and at the same time, it provides more diffuse reflection of light, has a better reflection effect, and improves the user's viewing experience to a greater extent.

[0060] As an optional embodiment, the radius of the convex arc surface 1 is R1, the radius of the concave arc surface 2 is R2, and the thickness of the sub-panel 20 is D; wherein, R2≥R1≥D / 2.

[0061] Optionally, in this embodiment, the radius of the concave arc surface 2 can be set to be greater than the radius of the convex arc surface 1, thereby ensuring that the concave portion 22 fully accommodates the convex portion 21. At the same time, the radii of the two arc surfaces can be set to be greater than half the thickness of the sub-panel 20, so that the two arc surfaces have a larger size range and form more sufficient diffuse reflection of light.

[0062] Optionally, the radii of the convex arc surface 1 and the concave arc surface 2 can be set to be equal and half the thickness of the sub-panel 20. This allows the convex part 21 and the concave part 22 to fit together more fully and precisely when adjacent sub-panels 20 are spliced, thus reducing the splicing gap between adjacent sub-panels 20 to a greater extent. This helps to reduce the seam between them and ultimately improve the overall display effect.

[0063] This invention provides a display panel 100, which further defines the dimensional relationship between the convex arc surface 1 and the concave arc surface 2, which is beneficial to achieve precise splicing of the convex part 21 and the concave part 22, while improving the diffuse reflection of light and reducing the splicing gap size, thus reducing the user's perception of the splicing gap.

[0064] As an optional embodiment, please refer to Figure 4 and Figure 5 Each sub-panel 20 includes a first surface and a second surface disposed opposite to each other along the thickness direction. The protrusion 21 and / or the recess 22 have a side surface connected between the first surface and the second surface. Along the direction from the first surface to the second surface, the side surface includes a plurality of sub-planes 3 connected in succession.

[0065] In addition to setting the surfaces of the protrusion 21 and the concave portion 22 as an outwardly convex arc surface 1 and an inwardly concave arc surface 2, the side surfaces of the protrusion 21 and the concave portion 22 can optionally be set as having a structure in which multiple sub-planes 3 are connected in succession. That is, the side surfaces of the protrusion 21 and the concave portion 22 are formed by connecting several sub-planes 3.

[0066] Optionally, each subplane 3 has a certain extension length, and adjacent subplanes 3 form a predetermined angle so that multiple subplanes 3 together constitute the side surfaces of the convex portion 21 and the concave portion 22. The aforementioned convex arc surface 1 and concave arc surface 2 can be understood as a structural form in which the extension length of each subplane 3 approaches zero infinitely.

[0067] The protrusions 21 and concave portions 22 formed by multiple sub-planes 3 can also be joined together to splice adjacent sub-panels 20. For multiple connected sub-planes 3, when light passes through the splicing position, the light will be reflected at different sub-planes 3. Since the different sub-planes 3 form a predetermined angle, the light will be reflected to different angle positions, which can also achieve diffuse reflection of light, avoid the concentration of reflected light, and reduce the display effect at the splicing point.

[0068] Optionally, the included angle between two adjacent sub-planes 3 is an obtuse angle, thereby ensuring that the side surface of the protrusion 21 is convex and the side surface of the concave part 22 is concave. As shown in the figure, the side surface can be set as a connection structure of five sub-planes 3. At this time, the included angle between two adjacent sub-planes 3 can be 150 degrees. Of course, the number and angle of the sub-planes 3 can also be adjusted according to the actual design requirements.

[0069] It is understandable that by setting the side surfaces of the protrusion 21 and the concave part 22 as multiple sub-planes 3, the more sub-planes 3 are set, the more reflection angles of light, and the better diffuse reflection effect of light, thus achieving a more aesthetically pleasing display effect. Therefore, optionally, the same side surface includes more than 5 sub-planes 3. This application does not make any special limitation on the specific number of sub-planes 3.

[0070] Different numbers of subplanes 3 will result in different included angles between adjacent subplanes 3. Usually, the included angle between adjacent subplanes 3 can be set to be equal. For example, when the side surface is set to five subplanes 3, the included angle can be 150 degrees. If six subplanes 3 are set, the included angle is about 154 degrees, and so on.

[0071] Optionally, the number of sub-planes 3 can be set to an odd number, so that after splicing, the plane of the protrusion 21 is aligned with the plane of the concave part 22, reducing the damage caused by the relative edges of adjacent sub-panels 20 after they are joined. Based on the diffuse reflection formed by the sub-planes 3, the structure of the sub-panel 20 is protected, and the probability of damage to the sub-panel 20 is reduced.

[0072] Of course, the angle between the sub-planes 3 or their respective extension lengths can also be controlled to adjust the actual structure of the protrusion 21 and the concave portion 22, thereby ensuring that the planes of the protrusion 21 and the concave portion 22 are opposite to each other. The side surfaces of the protrusion 21 and the concave portion 22 can be irregular shapes, which is not limited in this application.

[0073] Optionally, the extension lengths of multiple sub-planes 3 on the same side surface are equal, thereby enabling the protrusion 21 or the concave portion 22 to form a more regular side surface, which facilitates the docking of the two and is also beneficial for the processing and shaping of the side surfaces of the protrusion 21 and the concave portion 22. This application does not impose a special limitation on the specific extension length of the sub-plane 3, but needs to be comprehensively determined based on the actual number and angle of the sub-planes 3.

[0074] This invention provides a display panel 100, which sets the side surfaces of the protrusion 21 and the recess 22 as a connection structure of multiple sub-planes 3. While ensuring that the protrusion 21 and the recess 22 form a joint, the sub-planes 3 can also be used to diffusely reflect light, thereby reducing the impact of the splicing seam on the display. At the same time, it improves the design diversity of the protrusion 21 and the recess 22.

[0075] As an optional embodiment, please refer to Figure 4 and Figure 5 Both the protrusion 21 and the concave portion 22 include side surfaces, and the multiple sub-planes 3 of the protrusion 21 and the multiple sub-planes 3 of the concave portion 22 are arranged in a one-to-one correspondence.

[0076] In this embodiment, by matching the sub-planes 3 of the protrusion 21 and the concave part 22 one-to-one, the structural matching degree of the protrusion 21 and the concave part 22 is improved. That is, the number of sub-planes 3 of the protrusion 21 and the concave part 22 is set to be the same. Optionally, the extension length of the sub-plane 3 of the protrusion 21 and the extension length of the sub-plane 3 of the concave part 22 are equal, thereby further matching the structures of the protrusion 21 and the concave part 22.

[0077] Optionally, the included angle between adjacent sub-planes 3 of the protrusion 21 is equal to the included angle between adjacent sub-planes 3 of the concave portion 22, so that the shapes of the protrusion 21 and the concave portion 22 are perfectly matched and can accommodate each other. The preferred embodiment is a seamless connection between the protrusion 21 and the concave portion 22, thereby minimizing the size of the seam and reducing the impact of the seam on the display.

[0078] This invention provides a display panel 100. By setting the sub-planes 3 of the protrusion 21 and the concave 22 in a one-to-one correspondence, the matching degree of the protrusion 21 and the concave 22 is improved. Thus, while using the protrusion 21 and the concave 22 to complete the diffuse reflection of light, the gap between the two can also be reduced, thereby reducing the impact of the splicing seam on the display.

[0079] As an alternative embodiment, at least a portion of the protrusion 21 is accommodated in the recess 22.

[0080] Optionally, the protrusion 21 can be completely accommodated in the recess 22, or it can be partially accommodated in the recess 22. An appropriate gap can be formed between the protrusion 21 and the recess 22, so that the light can be diffusely reflected by the protrusion 21 and the recess 22.

[0081] Optionally, the protrusion 21 abuts against the concave portion 22, and the side surface of the protrusion 21 and the side surface of the concave portion 22 have the same shape and contour. The protrusion 21 and the concave portion 22 are seamlessly joined, so that the seam between the protrusion 21 and the concave portion 22 can be eliminated, achieving the most ideal structural state and thus avoiding the impact of the seam on the display.

[0082] This invention provides a display panel 100, which achieves splicing between adjacent sub-panels 20 through the accommodating cooperation of the protrusion 21 and the concave portion 22. In addition to utilizing the diffuse reflection of light by the protrusion 21 and the concave portion 22, it can also improve the splicing strength between adjacent sub-panels 20 and has higher structural stability.

[0083] As an optional embodiment, please refer to Figure 1 The display panel 100 includes a connecting layer 30 disposed on the substrate 10, and a plurality of sub-panels 20 disposed on the side of the connecting layer 30 away from the substrate 10. The plurality of sub-panels 20 are connected to the substrate 10 through the connecting layer 30.

[0084] Optionally, the connecting layer 30 can be an optical adhesive, which can be a flowable adhesive or a solid optical transparent adhesive, and can be bonded multiple times to form a transparent display screen structure. The substrate 10 can be a high-transmittance material with a transmittance of ≥95%, such as AR glass, as long as it can ensure light transmission.

[0085] At this time, multiple sub-panels 20 are bonded to the substrate 10 through the connecting layer 30. Optionally, the substrate 10 includes a first light-transmitting plate 11 and a second light-transmitting plate 12. The connecting layer 30 includes a first optical adhesive layer 31 and a second optical adhesive layer 32. The first optical adhesive layer 31 is disposed on the first light-transmitting plate 11 and the second optical adhesive layer 32 is disposed on the second light-transmitting plate 12. The first optical adhesive layer 31 and the second optical adhesive layer 32 are disposed opposite to each other and the multiple sub-panels 20 are sandwiched between them.

[0086] Therefore, the above-mentioned multiple sub-panels 20 can be disposed between the first light-transmitting plate 11 and the second light-transmitting plate 12. At the same time, the first optical adhesive layer 31 and the second optical adhesive layer 32 are used to bond the sub-panels 20 on the upper and lower sides respectively. While the adjacent sub-panels 20 are connected by the protrusions 21 and the recesses 22, the whole is bonded by optical adhesive.

[0087] When there is a gap between the protrusion 21 and the recess 22, the upper second optical adhesive layer 32 can fill the gap, thereby ensuring the reliability of the connection between adjacent sub-panels 20, without affecting the light transmission, and further improving the connection stability of the structure.

[0088] This invention provides a display panel 100, which uses a connecting layer 30 to bond a sub-panel 20 to a substrate 10. Based on the use of protrusions 21 and recesses 22 to form an abutment between adjacent sub-panels 20, the sub-panels 20 are further fixed to the substrate 10, ensuring the structural load-bearing strength and providing better light transmission.

[0089] As an optional embodiment, the sub-panel 20 includes a plurality of protrusions 21 and adjacent sub-panels 20 include a plurality of recesses 22 corresponding to the protrusions 21, with at least a portion of each protrusion 21 being received in its respective corresponding recess 22.

[0090] Optionally, in order to further improve the diffuse reflection effect of the protrusions 21 and the recesses 22 on light, multiple protrusions 21 can be provided on the sub-panel 20 and multiple recesses 22 corresponding to the protrusions 21 can be provided on adjacent sub-panels 20, forming a one-to-one match between the protrusions 21 and the recesses 22.

[0091] Optionally, this application does not impose a special limitation on the specific number of protrusions 21 and recesses 22 provided on the sub-panel 20, which can be determined according to the actual connection requirements and light reflection requirements.

[0092] This invention provides a display panel 100, which, through the docking action of multiple protrusions 21 and recesses 22, can diffusely reflect light to a greater extent, further reducing the impact of seams on the display. At the same time, by utilizing the docking of multiple protrusions 21 and multiple recesses 22, the connection strength between adjacent sub-panels 20 is improved, resulting in higher structural stability of the screen.

[0093] According to an embodiment of the present invention, a display device is provided, including the display panel 100 as described above.

[0094] This invention provides a display panel and a display device. By providing a protrusion on one of two adjacent sub-panels and a recess on the other, the two sub-panels are spliced ​​together using the interlocking fit of the protrusion and recess. Because of the protrusion and recess between the two adjacent sub-panels, light undergoes diffuse reflection at the splicing point, avoiding light concentration caused by total emission. This prevents the seam from being clearly visible at the splicing point. The structural fit of the protrusion and recess reduces the visual impact of the seam, thereby improving the overall display effect. Simultaneously, the interlocking fit of the protrusion and recess improves the connection stability between adjacent sub-panels, giving the screen better structural strength. While improving the display effect at the seam, it also ensures the overall strength of the spliced ​​screen.
