Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] The new generation of display technology pursues large-area and diversified display effects. Due to the limitations of the manufacturing process of large-size display screens, splicing display technology was born. The requirements of display splicing technology are high-precision splicing of screens, and the splicing seam should be invisible to the naked eye. However, physical splicing seams and height differences are inevitable in splicing displays. Therefore, due to the influence of physical splicing seams and height differences in splicing displays, there are problems such as the inability to achieve a seamless splicing effect and the impact on product display performance. Summary of the Invention

[0003] The main technical problem addressed by this application is to provide a display panel and display device that can reduce the seam formed when splicing the display screen of a splicing unit with other display screens.

[0004] To solve the above-mentioned technical problems, the first technical solution adopted in this application is to provide a display panel, including a splicing unit, wherein the splicing unit includes a support plate and at least one display screen, the at least one display screen being disposed on the support plate; the first edge of the support plate is recessed relative to the third edge of the display screen on the side close to the first edge of the support plate.

[0005] The splicing unit further includes a drive unit housing, the second edge of which is recessed relative to the third edge of the display screen on the side adjacent to the second edge of the drive unit housing.

[0006] The splicing unit further includes a drive unit housing. The display screen is disposed on one side of the support plate, and the drive unit housing is disposed on the other side of the support plate opposite to the display screen. The second edge of the drive unit housing near the first edge of the support plate is recessed relative to the third edge of the display screen near the first edge of the support plate.

[0007] The inward width of the second edge of the drive unit housing is smaller than the inward width of the first edge of the support plate.

[0008] Wherein, the inward width of the first edge of the support plate is 100-500 μm; and / or, the inward width of the second edge of the drive unit housing is 50-300 μm.

[0009] The display panel includes at least two splicing units, which are arranged side by side. Any two adjacent splicing units are joined together by the third edge of the display screen on the side of the first edge of the support plate.

[0010] The support plate has at least one receiving groove on its edge.

[0011] The display screen includes a screen body and an external circuit board located on the side away from the light-emitting surface of the screen body. The light-emitting surface of the screen body is disposed away from the support plate, and the external circuit board is inserted into the receiving groove.

[0012] The drive unit housing has a receiving space at a position corresponding to the receiving groove of the support plate.

[0013] To solve the above-mentioned technical problems, the second technical solution adopted in this application is to provide a display device, which includes any of the above-mentioned display panels.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a display panel and display device. The display panel includes a splicing unit, which includes a support plate and at least one display screen. The at least one display screen is disposed on the support plate. The first edge of the support plate is recessed relative to the third edge of the display screen closest to the first edge of the support plate. By setting the first edge of the support plate to be recessed relative to the third edge of the display screen closest to the first edge of the support plate, when splicing the splicing unit with other splicing units, the first edge of the support plate will not touch the edges of the support plates of other splicing units, thus avoiding the support plate obstructing the connection between the display screens. Therefore, the third edge of the display screen closest to the first edge of the support plate can be seamlessly connected with the third edge of the display screen in other splicing units that is also close to the first edge of the support plate. Since the edges of the display screens are generally non-display areas, seamless connection between the display screens can reduce the leakage of non-display areas of the spliced ​​display screens, thereby achieving full-screen display of the product and improving product display performance.

[0040] This application provides a display panel. Please refer to [link / reference]. Figure 1 , Figure 1This is a side view of the first embodiment of the display panel of this application. In this embodiment, the display panel includes a splicing unit 10, which includes a support plate 100 and at least one display screen 101. The at least one display screen 101 is disposed on the support plate 100. The first edge 1000 of the support plate 100 is recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100. By setting the first edge 1000 of the support plate 100 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100, the first edge 1000 of the support plate 100 will not touch the edge of the support plate 100 of the other splicing unit 10 when splicing the splicing unit 10 with other splicing units 10. This avoids the support plate 100 from obstructing the docking between the display screens 101. Thus, the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100 can be seamlessly docked with the third edge 1013 of the display screen 101 of the other splicing unit 10. Since the edge of the display screen 101 is generally a non-display area, the seamless docking between the display screens 101 can reduce the leakage of the non-display area of ​​the splicing display screen 101, thereby achieving full-screen display of the product and improving the product display performance.

[0041] In one embodiment, the splicing unit 10 may include only one display screen 101. When manufacturing the splicing unit 10, the single display screen 101 can be manufactured first. The display screen 101 does not have a display bezel and can be manufactured using processes such as side wiring and high-precision cutting. Then, the single display screen 101 is bonded to the support plate 100 using an adhesive layer 102, thus mounting the single display screen 101 onto the support plate 100 to obtain the splicing unit 10 with one display screen 101. Then, the splicing unit 10 can be spliced ​​with other splicing units 10 to form a larger display panel. Please refer to... Figure 1 and Figure 2 , Figure 2This is a side view of the second embodiment of the display panel of this application. Specifically, the splicing unit 10 may include multiple displays 101, which are regularly arranged and disposed on one side of the support plate 100. When manufacturing the display panel of the above embodiment, a single display 101 can be manufactured first. The display 101 does not have a display frame and can be manufactured using processes such as side wiring and high-precision cutting. Then, the single display 101 is bonded to the support plate 100 through an adhesive layer 102, thereby splicing multiple displays 101 onto the support plate 100. That is, multiple single displays 101 are spliced ​​in one splicing unit 10 to obtain the splicing unit 10. Then, the splicing unit 10 can be spliced ​​with other splicing units 10 to form a larger display panel, so that the product can be stacked to achieve the splicing of 2*n or even n*n displays 101.

[0042] In one embodiment, the support plate 100 may be made of ultra-flat glass or alloy plate, so that after multiple displays 101 are installed on the support plate 100, the surfaces of each display 101 can be made to have the same height, thereby reducing the visual splicing seam caused by height difference.

[0043] Please see Figure 3 , Figure 3This is a side view of the third embodiment of the display panel of this application. Based on the previous embodiment, in this embodiment, the splicing unit 10 further includes a driving unit housing 103, and the second edge 1030 of the driving unit housing 103 is recessed relative to the third edge 1013 of the display screen 101 on the side closest to the second edge 1030 of the driving unit housing 103. It can be understood that by bringing the driving unit housing 103 in the splicing unit 10, together with the support plate 100 and the display screen 101 on the support plate 100, close to and connecting it with other splicing units 10, the splicing unit 10 can be spliced ​​with other splicing units 10; by setting the second edge 1030 of the driving unit housing 103 to be recessed relative to the third edge 1013 of the display screen 101 on the side closest to the second edge 1030 of the driving unit housing 103, when splicing the splicing unit 10 with other splicing units 10, the second edge 1030 of the driving unit housing 103 and the third edge 1013 of the display screen 101 on the side closest to the second edge 1030 of the driving unit housing 103 are... The edges of the drive unit housings 103 of other splicing units 10 will not touch each other, thus avoiding the drive unit housings 103 from obstructing the docking between the displays 101. Therefore, the third edge 1013 of the display 101 on the side of the second edge 1030 of the drive unit housing 103 can be seamlessly docked with the third edge 1013 of the displays 101 of other splicing units 10. Since the edges of the displays 101 are generally non-display areas, the seamless docking between the displays 101 can reduce the leakage of the non-display areas of the splicing displays 101, thereby achieving full-screen display of the product and improving the product display performance.

[0044] Please continue reading. Figure 3In one embodiment, the display panel includes a splicing unit 10, which includes a support plate 100, a drive unit housing 103, and at least one display screen 101. The at least one display screen 101 is disposed on the support plate 100 and on one side of the support plate 100. The drive unit housing 103 is disposed on the other side of the support plate 100 opposite to the display screen 101. The first edge 1000 of the support plate 100 is recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100. The second edge 1030 of the drive unit housing 103 on the side close to the first edge 1000 of the support plate 100 is recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100. Specifically, the splicing unit 10 includes a drive unit housing 103, a support plate 100, and a display screen 101 stacked sequentially from bottom to top. By bringing the drive unit housing 103, along with the support plate 100 and the display screen 101 on the support plate 100, together as a whole, close to and connecting with other splicing units 10, the splicing unit 10 can be spliced ​​with other splicing units 10. Furthermore, by setting the second edge 1030 of the drive unit housing 103 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100, and setting the first edge 1000 of the support plate 100 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100, the splicing unit 10 can be spliced ​​with other splicing units. When splicing 10 units, the second edge 1030 of the drive unit housing 103 will not touch the edges of the drive unit housing 103 of other splicing units 10, and the first edge 1000 of the support plate 100 will not touch the edges of the support plate 100 of other splicing units 10. This avoids the drive unit housing 103 and the support plate 100 from obstructing the docking between the display screens 101. Thus, the third edge 1013 of the display screen 101 on the side closer to the second edge 1030 of the drive unit housing 103 can be seamlessly docked with the third edge 1013 of the display screens 101 of other splicing units 10. Since the edges of the display screens 101 are generally non-display areas, the seamless docking between the display screens 101 can reduce the leakage of non-display areas of the spliced ​​display screens 101, thereby achieving full-screen display of the product and improving the product display performance.

[0045] Please see Figure 4 , Figure 4This is a side view structural diagram of the fourth embodiment of the display panel of this application. In this embodiment, the display panel includes at least two splicing units 10, which are arranged side by side. Any two adjacent splicing units 10 are connected by the third edge 1013 of the display screen 101 on the side near the first edge 1000 of the support plate 100.

[0046] In one embodiment, the inward width b of the second edge 1030 of the drive unit housing 103 is less than the inward width a of the first edge 1000 of the support plate 100, i.e., b is greater than 0 and less than a. Optionally, the inward width a of the support plate 100 is 100 to 500 μm, for example, the inward width a of the support plate 100 can be specifically set to 300 μm, 350 μm, 400 μm, or 450 μm. Optionally, the inward width b of the drive unit housing 103 is 50 to 300 μm, for example, the inward width b of the drive unit housing 103 can be specifically set to 100 μm, 150 μm, 200 μm, or 250 μm. By setting the first edge 1000 of the support plate 100 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100, with a recess distance a greater than 0 μm, and setting the second edge 1030 of the drive unit housing 103 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the second edge 1030 of the drive unit housing 103, with a recess distance b greater than 0 and less than a, the splicing seam between adjacent splicing units 10 can be minimized.

[0047] In one embodiment, the display panel is formed by splicing multiple splicing units 10, which are regularly arranged and fixed together. When manufacturing the display panel, a single display screen 101 can be manufactured first. The display screen 101 does not have a display border; for example, it can be manufactured using side wiring, high-precision cutting, or other processes. Then, the single display screen 101 is bonded to the support plate 100 using an adhesive layer 102. This allows multiple display screens 101 to be spliced ​​onto the support plate 100, resulting in splicing units 10. These splicing units 10 can then be further spliced ​​with other splicing units 10 to form a larger display panel. This reduces the difficulty of splicing the display screens 101 and allows for the free splicing of several display screens 101.

[0048] Please combine Figure 5a and Figure 5b ,in, Figure 5a This is a schematic diagram of the structure of a support plate in an embodiment of the display panel of this application. Figure 5b yes Figure 5aA top view of the support plate is shown. In one embodiment, at least one receiving groove 1001 is provided on the edge of the support plate 100. Specifically, the support plate 100 can be rectangular, and receiving grooves 1001 are provided on the edges of the two opposite first sides of the support plate 100, and / or receiving grooves 1001 are provided on the edges of the two opposite second sides of the support plate 100.

[0049] Please combine Figures 5a to 6d ,in, Figure 6a This is a top view of one embodiment of the display screen in the display panel of this application. Figure 6b yes Figure 6a A side view diagram of the display screen. Figure 6c yes Figure 6a A top view diagram of the external circuit board in the display screen. Figure 6d yes Figure 6a A side view of the external circuit board in the display screen. Further, the display screen 101 includes a screen body 1010 and an external circuit board 1012 located on the side away from the light-emitting surface 1011 of the screen body 1010. The light-emitting surface 1011 of the screen body 1010 is disposed away from the support plate 100, and the external circuit board 1012 is inserted into the receiving groove 1001. Specifically, the receiving slot 1001 can be used to avoid and hide the external circuit board 1012 of the display screen 101. The external circuit board 1012 is placed on the back of the support plate 100 through the receiving slot 1001, away from the display surface. It can be understood that since the external circuit board 1012 is located in the receiving slot 1001, the external circuit board 1012 does not occupy the bezel size of the splicing unit 10, thereby eliminating the display bezel of the splicing unit 10. As a result, when the splicing unit 10 is spliced ​​with other splicing units 10, the splicing unit 10 has no bezel structure at the joint position due to the bezel-less structure of the splicing unit 10, forming a seamless splicing screen, thereby realizing the full-screen display of the splicing screen.

[0050] In one embodiment, such as Figure 5a and Figure 5b As shown, the support plate 100 is rectangular. n receiving slots 1001 are respectively provided on the edges of the two opposite first sides of the support plate 100. These 2n receiving slots 1001 are symmetrical about the center line C of the support plate 100. Therefore, 2n display screens 101 can be spliced ​​onto the support plate 100, achieving a splicing of 2*n display screens 101. In other embodiments, n receiving slots 1001 can be respectively provided on the edges of the two opposite second sides of the support plate 100, thus allowing 2n display screens 101 to be spliced ​​onto the support plate 100, achieving a splicing of 2*n display screens 101.

[0051] In one embodiment, the receiving groove 1001 is rectangular and has rounded corners or C-shaped corners, which can increase the strength of the support plate 100.

[0052] Please combine Figures 5a to 6d , Figure 7a ,in, Figure 7a This is a schematic diagram of a structure of one embodiment of the display panel in the present application, showing the process of mounting the display screen on the support plate. The projection of the external circuit board 1012 of the display screen 101 onto the plane containing the light-emitting surface 1011 of the display screen 101 is at least partially located outside the light-emitting surface 1011 of the display screen 101. It can be understood that... Figure 6a The display screen 101 is installed Figure 5a During the process of mounting the display screen 101 on the support plate 100, the external circuit board 1012 of the display screen 101 can be inserted into the receiving groove 1001. Optionally, the external circuit board 1012 of the display screen 101 is a flexible circuit board. The receiving groove length L2 of the receiving groove 1001 is greater than the length L of the external circuit board 1012 of the display screen 101; the receiving groove width W2 of the receiving groove 1001 is greater than the thickness H of the external circuit board 1012 of the display screen 101. Specifically, the receiving groove length L2 of the receiving groove 1001 extending along the edge of the support plate 100 is greater than the length L of the external circuit board 1012 of the display screen 101 extending along the edge of the support plate 100; the receiving groove width W2 of the receiving groove 1001 extending perpendicular to the edge of the support plate 100 is greater than the thickness H of the external circuit board 1012 of the display screen 101. Since the length L2 of the receiving groove 1001 is greater than the length L of the external circuit board 1012, the external circuit board 1012 can be accommodated within the length range of the receiving groove 1001 after bending. Furthermore, since the width W2 of the receiving groove 1001 is greater than the thickness H of the external circuit board 1012, the thickness direction of the bent external circuit board 1012 is accommodated within the width range of the receiving groove 1001. Therefore, the external circuit board 1012 is not exposed outside the frame of the splicing unit 10, and the external circuit board 1012 does not affect the frame size of the splicing unit 10.

[0053] Furthermore, the drive unit housing 103 has a corresponding accommodating space (not shown) at a position corresponding to the accommodating groove 1001 of the support plate 100. For example... Figure 8 As shown, it can be understood that since the receiving groove 1001 is used to avoid and hide the external circuit board 1012 of the display screen 101, the external circuit board 1012 can be placed on the back of the support plate 100 through the receiving groove 1001. Therefore, a receiving space should be provided on the drive unit housing 103 on the back of the support plate 100 at the position corresponding to the receiving groove 1001 of the support plate 100. The receiving space can accommodate the external circuit board 1012, so that the external circuit board 1012 located on the back of the support plate 100 can extend into the drive unit housing 103.

[0054] Please see Figure 8 , Figure 8 This is a side view of the fifth embodiment of the display panel of this application. The display panel includes at least two splicing units 10, which are arranged side by side. Any two adjacent splicing units 10 are joined together by the third edge 1013 of the display screen 101 near the first edge 1000 of the support plate 100. During the process of mounting the display screen 101 on the support plate 100, the external circuit board 1012 of the display screen 101 can be bent and inserted into the receiving groove 1001. Optionally, the external circuit board 1012 of the display screen 101 is a flexible circuit board. The SS area in the figure is the area of ​​the support plate 100 where the receiving groove 1001 is formed.

Figure 6f This is a side view structural diagram of another embodiment of the display screen in the display panel of this application. Figure 7b This is a schematic diagram of another embodiment of the process of mounting the display screen on the support plate in the display panel of this application. In one embodiment, a display screen 101 has multiple external circuit boards 1012, which are arranged side by side. During the process of mounting the display screen 101 on the support plate 100, the multiple external circuit boards 1012 of the display screen 101 can be bent and inserted into the same receiving slot 1001. Of course, in other embodiments, the multiple external circuit boards 1012 of the display screen 101 can also be bent and inserted into different receiving slots 1001.

[0056] Please combine Figure 7c , Figure 7c This is a schematic diagram of another embodiment of the process of installing the display screen in the display panel of this application onto the support plate. In one embodiment, multiple display screens 101 are arranged side by side on the support plate 100, and each display screen 101 has an external circuit board 1012. Thus, the multiple external circuit boards 1012 corresponding to the multiple display screens 101 are arranged side by side. During the process of installing the multiple display screens 101 onto the support plate 100, the multiple external circuit boards 1012 corresponding to the multiple display screens 101 can be bent and inserted into the same receiving slot 1001.

[0057] It is understood that multiple external circuit boards 1012 can be bent and inserted into one or more receiving slots 1001. The number of external circuit boards 1012 and receiving slots 1001 can be many-to-one, many-to-many, or one-to-one. The shape, size, position, and number of external circuit boards 1012 accommodated by the receiving slots 1001 on the support plate 100 are set according to the shape, size, position, and number of external circuit boards 1012 on the display screen 101.

In addition to having at least one receiving groove 1001 at the edge of the support plate 100, at least one receiving hole 1002 is further provided in the middle region of the support plate 100.

[0059] Please combine Figure 9a , Figure 9b , Figure 10 as well as Figure 6c and Figure 6d ,in, Figure 10 This is a side view of an embodiment of the display screen in the display panel of this application. Further, the display screen 101 located in the middle region of the support plate 100 includes a screen body 1010 and an external circuit board 1012 located on the side away from the light-emitting surface 1011 of the screen body 1010. The light-emitting surface 1011 of the screen body 1010 is disposed away from the support plate 100, and the external circuit board 1012 is accommodated in the receiving hole 1002. Specifically, the projection of the external circuit board 1012 of the display screen 101 onto the plane where the light-emitting surface 1011 of the display screen 101 is located is entirely on the light-emitting surface 1011 of the display screen 101; please refer to... Figure 11 , Figure 11 This is a schematic diagram of another embodiment of the display screen in the display panel of this application during the process of mounting the display screen on the support plate. It can be understood that... Figure 10 The display screen 101 is installed Figure 9a During the process of mounting the display screen 101 on the support plate 100, the external circuit board 1012 of the display screen 101 can be accommodated in the receiving hole 1002. Specifically, the receiving hole 1002 can be used to avoid and hide the external circuit board 1012 of the display screen 101, and place the external circuit board 1012 on the back of the support plate 100 through the receiving hole 1002, away from the display surface.

[0060] In one embodiment, such as Figure 9a and Figure 9bAs shown, the support plate 100 is rectangular, and a plurality of receiving holes 1002 are provided in the middle area of ​​the support plate 100. The plurality of receiving holes 1002 are arranged in a matrix in the middle area of ​​the support plate 100. Combined with the above-mentioned receiving slots 1001, the external circuit board 1012 of the display screen 101 located in the edge area of ​​the support plate 100 is inserted into the receiving slot 1001 on the support plate 100, and the external circuit board 1012 of the display screen 101 located in the middle area of ​​the support plate 100 is inserted into the receiving holes 1002 on the support plate 100. n*n display screens 101 can be spliced ​​on the support plate 100 to realize the splicing of n*n display screens 101.

[0061] In one embodiment, the receiving hole 1002 is rectangular and has rounded corners or C-shaped corners, which can increase the strength of the support plate 100.

[0062] In one embodiment, such as Figure 9b and Figure 6c As shown, the length L1 of the receiving hole 1002 is greater than the length L of the external circuit board 1012 of the display screen 101; the width W1 of the receiving hole 1002 is greater than the width W of the external circuit board 1012 of the display screen 101. Because the length L1 of the receiving hole 1002 is greater than the length L of the external circuit board 1012, the external circuit board 1012 can be accommodated within the length range of the receiving hole 1002. And because the width W1 of the receiving hole 1002 is greater than the width W of the external circuit board 1012, when the external circuit board 1012 is a flexible circuit board or a rigid circuit board, its width direction can be accommodated within the width range of the receiving hole 1002. Therefore, the external circuit board 1012 can be completely placed within the frame of the second display screen 101b.

[0063] Furthermore, a receiving space is provided on the drive unit housing 103 at a position corresponding to the receiving hole 1002 of the support plate 100. It can be understood that since the receiving hole 1002 is used to avoid and hide the external circuit board 1012 of the display screen 101, the external circuit board 1012 can be placed on the back of the support plate 100 through the receiving hole 1002. Therefore, a receiving space should be provided on the drive unit housing 103 on the back of the support plate 100 at a position corresponding to the receiving hole 1002 of the support plate 100, and the receiving space can accommodate the external circuit board 1012.

[0064] In one embodiment, a display screen 101 has an external circuit board 1012. During the process of mounting the display screen 101 onto the support plate 100, the external circuit board 1012 of the display screen 101 can be accommodated in a corresponding receiving hole 1002. In another embodiment, a display screen 101 has multiple external circuit boards 1012 arranged side by side. During the process of mounting the display screen 101 onto the support plate 100, the multiple external circuit boards 1012 of the display screen 101 can be accommodated in the same receiving hole 1002, or the multiple external circuit boards 1012 of the display screen 101 can be accommodated in different receiving holes 1002.

[0065] It is understood that multiple external circuit boards 1012 can be bent and inserted into one or more receiving holes 1002. The number of external circuit boards 1012 and receiving holes 1002 can be many-to-one, many-to-many, or one-to-one. The shape, size, position, and number of external circuit boards 1012 received by the receiving holes 1002 on the support plate 100 are set according to the shape, size, position, and number of external circuit boards 1012 of the display screen 101.

[0066] This application also provides a display device (not shown), which includes any of the above-described display panels.

[0067] In summary, in the display panel of the display device of this application, by setting the first edge 1000 of the support plate 100 to be recessed relative to the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100, when splicing the splicing unit 10 with other splicing units 10, the first edge 1000 of the support plate 100 and the edge of the support plate 100 of other splicing units 10 will not touch, thus avoiding the support plate 100 from obstructing the docking between the display screens 101. Therefore, the third edge 1013 of the display screen 101 on the side close to the first edge 1000 of the support plate 100 can be seamlessly docked with the third edge 1013 of the display screen 101 of other splicing units 10. Since the edge of the display screen 101 is generally a non-display area, the seamless docking between the display screens 101 can reduce the leakage of the non-display area of ​​the splicing display screen 101, thereby achieving full-screen display of the product and improving the product display performance.
