Abstract
Description
Technical Field
[0001] This application relates to the field of display panel technology, and in particular to a splicing display panel and display device. Background Technology
[0002] With the booming development of various types of display panels, Mini LED (mini light emitting diode) and Micro LED (micro light emitting diode) technologies are receiving increasing attention from display panel manufacturers. The advantage of Mini LED and Micro LED display technologies lies in the ability to create a basic-sized panel unit and then infinitely splice them together to achieve large-size panel displays.
[0003] However, each Mini LED panel unit and Micro LED panel unit typically requires an adaptive bonding package area for wiring to connect to the corresponding driving system. Since Mini LED chips cannot be placed in this bonding package area, a large seam inevitably exists after splicing different panel units. Summary of the Invention
[0004] The main technical problem this application addresses is to provide a splicing display panel and display device to solve the problem of large seams in existing splicing display panels.
[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a splicing display panel, wherein the splicing display panel includes: a first display panel, including an adjacent first side and a second side, and a first trace is provided on the first side; a second display panel, including an adjacent third side and a fourth side, the third side being spliced with the second side, the fourth side being away from the first side, and a second trace is provided on the fourth side, the second trace being connected to the first trace.
[0006] A third trace is provided on the second side, with one end of the third trace connected to the first trace and the other end of the third trace connected to the second trace.
[0007] There are multiple third traces, which are spaced apart from each other. The third side has a first groove corresponding to each third trace, and each third trace is embedded in the first groove.
[0008] A fourth trace is provided on the third side, one end of which is connected to the second trace, and the other end of which is connected to the first trace.
[0009] There are multiple fourth lines, which are spaced apart from each other. The second side has a second groove for each fourth line, and each fourth line is embedded in the second groove.
[0010] The fifth wiring is provided on the second side and the sixth wiring is provided on the third side. One end of the fifth wiring is connected to the second wiring, the other end of the fifth wiring is connected to one end of the sixth wiring, and the other end of the sixth wiring is connected to the second wiring.
[0011] The second or third side is provided with a third groove, and the fifth and sixth wirings are both embedded in the third groove.
[0012] The second side is provided with a protrusion, and the third side is provided with a mounting groove corresponding to the protrusion, with the protrusion embedded in the mounting groove; or, the third side is provided with a protrusion, and the second side is provided with a mounting groove corresponding to the protrusion, with the protrusion embedded in the mounting groove.
[0013] The splicing display panel also includes a driving control circuit. The first side has a first display area and a first non-display area. The first display area has a plurality of first light-emitting devices arranged in an array. The first non-display area has a first trace, and each first light-emitting device is connected to the first trace. The fifth side of the second display panel has a second display area and a second non-display area. The second display area has a plurality of second light-emitting devices arranged in an array. The second non-display area has a seventh trace, and each second light-emitting device is connected to the seventh trace. The seventh trace is used to connect to a second trace in another second display panel. The second trace is used to connect to the driving control circuit. The fifth side and the fourth side are opposite sides.
[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a display device, wherein the display device includes a housing and a splicing display panel connected to each other; wherein the splicing display panel is the splicing display panel as described in any of the above claims.
[0015] The beneficial effects of this application are as follows: Unlike the prior art, the first display panel in the splicing display panel provided by this application includes an adjacent first side and a second side, with a first trace on the first side. The second display panel includes an adjacent third side and a fourth side, with the third side spliced with the second side and the fourth side facing away from the first side. The fourth side is provided with a second trace, which connects to the first trace. This allows for minimizing the seam by placing the conductive leads used for connecting to the drive control circuit on different panel units. It also effectively avoids the problem of asynchronous fabrication processes on the two sides of the same panel unit, which can easily lead to a shift in the characteristics of the light-emitting devices, affecting the display and causing the leads to open circuits.

[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of one embodiment of the splicing display panel of this application. Figure 2 yes Figure 1 An exploded view of the splicing display panel. In this embodiment, the splicing display panel 1 specifically includes: a first display panel 10 and a second display panel 20.
[0026] It is worth noting that the splicing display panel 1 specifically refers to a large-size display panel obtained by splicing together multiple basic-size panel units equipped with Mini LEDs or Micro LEDs; and in this embodiment, the first display panel 10 and the second display panel 20 spliced together are used as a basic-size panel unit, and splicing is achieved by combining with other panel units that can be combined with a larger number of other first display panels 10 and second display panels 20, thereby obtaining a large-size splicing display panel 1.
[0027] Specifically, the first display panel 10 includes an adjacent first side 11 and a second side 12, and a first wiring 111 is provided on the first side 11; wherein, for ease of explanation, the first side 11 can be specifically understood as the front of the first display panel 10 where the light-emitting device and the connecting wiring are disposed, while the side opposite to the first side 11 where the light-emitting device is disposed, that is, the side that is disposed away from it, is the back side, and the second side 12 is specifically the assembly side intended to be spliced with the second display panel 20.
[0028] Furthermore, the second display panel 20 includes an adjacent third side (not shown) and a fourth side 21. The third side can be specifically understood as the assembly side of the second display panel 20, while the fourth side 21 is the back side. That is, the third side is spliced with the second side 12 of the first display panel 10 to assemble the second display panel 20 with the first display panel 10.
[0029] The fourth side 21 is opposite to the first side 11 of the first display panel 10, and a second trace 211 is provided on the fourth side 21. The second trace 211 is connected to the first trace 111 for connection with the corresponding driving control circuit, so that the light-emitting device in the first display panel 10 can be connected to the driving control circuit through the first trace 111 and the second trace 211 respectively provided on different panels.
[0030] The above solution minimizes the seam gap by placing the conductive leads used to connect to the drive control circuit on different panel units. Furthermore, by placing the first trace 111 on the front of the first display panel 10 and the second trace 211 on the back of the second display panel 20, it is ensured that they do not interfere with each other during manufacturing. This effectively avoids the problem of asynchronous manufacturing processes on the two sides of the same panel unit, which can easily lead to the deviation of the light-emitting device characteristics affecting the display and the problem of open circuits in the leads.
[0031] In one embodiment, a third trace 121 is further provided on the second side 12 of the first display panel 10. One end of the third trace 121 is connected to the first trace 111, and the other end of the third trace 121 is connected to the second trace 211, so that the first trace 111 can be connected to the second trace 211 through the third trace 121.
[0032] Furthermore, in one embodiment, the number of the third traces 121 is specifically multiple, and the multiple third traces 121 are specifically arranged parallel to each other on the second side 12 of the first display panel 10. On the third side of the second display panel 20, a first groove (not shown) is specifically provided for each third trace 121, and each third trace 121 is specifically embedded in the first groove. This not only realizes the connection between the first trace 111 and the second trace 211, but also enables the first display panel 10 to be spliced more tightly and firmly with the second display panel 20, and effectively reduces the seam.
[0033] In another embodiment, a fourth trace (not shown) is provided on the third side of the second display panel 20. One end of the fourth trace is connected to the second trace 211, and the other end of the fourth trace is connected to the first trace 111, so that the first trace 111 can be connected to the second trace 211 through the fourth trace.
[0034] Furthermore, in one embodiment, the number of the fourth traces is specifically multiple, and the multiple fourth traces are specifically arranged parallel to each other on the third side of the second display panel 20. On the second side 12 of the first display panel 10, a second groove (not shown) is specifically provided for each of the fourth traces, and each fourth trace is specifically embedded in the second groove. This not only realizes the connection between the first trace 111 and the second trace 211, but also enables the first display panel 10 to be spliced more tightly and firmly with the second display panel 20, and effectively reduces the seam.
[0035] In another embodiment, a fifth trace (not shown) is specifically provided on the second side 12 of the first display panel 10, and a sixth trace (not shown) is provided on the third side of the second display panel 20. One end of the fifth trace is specifically connected to the second trace 211, and the other end of the fifth trace is connected to one end of the sixth trace, while the other end of the sixth trace is correspondingly connected to the second trace 211, so that the first trace 111 can be connected to the second trace 211 through the fifth trace and the sixth trace.
[0036] Furthermore, in one embodiment, a third groove (not shown) is provided on the second side 12 of the first display panel 10 or on the third side of the second display panel 20, and the fifth and sixth traces are connected by the third groove, that is, both are embedded in the third groove.
[0037] In one embodiment, a protrusion (not shown) is provided on the second side 12 of the first display panel 10, and a mounting groove (not shown) is provided on the third side of the second display panel 20 corresponding to the protrusion. The protrusion is embedded in the mounting groove so that the first display panel 10 can be spliced with the second display panel 20 more tightly and firmly, and the seam can be effectively reduced.
[0038] Optionally, the number of protrusions can be two, and they can be specifically located near the opposite two edges of the second side 12. Alternatively, the number of protrusions can be one or more, and they can be located in the middle of the second side 12, between each two adjacent third lines 121, or in any other reasonable location. This application does not limit this.
[0039] In another embodiment, a protrusion is provided on the third side of the second display panel 20, and a mounting groove is provided on the second side 12 of the first display panel 10 corresponding to the protrusion. The protrusion is embedded in the mounting groove so that the first display panel 10 can be spliced more tightly and firmly with the second display panel 20, and the splicing gap can be effectively reduced.
[0040] In one embodiment, the splicing display panel 1 further includes a drive control circuit, and the second trace 211 in the second display panel 20 is specifically used to connect the drive control circuit.
[0041] The first display panel 10 has a first display area 101 and a first non-display area 102 on its first side 11. The first display area 101 is provided with a plurality of first light-emitting devices 112 arranged in an array, and the first non-display area 102 is provided with a first trace 111. Each light-emitting device is connected to the first trace 111. When the first trace 111 is connected to the second trace 211, each first light-emitting device 112 in the first display panel 10 can be connected to the driving control circuit through the first trace 111 and the second trace 211, so as to be controlled by the driving control circuit to perform corresponding image display.
[0042] The fifth side 22 of the second display panel 20 also has a second display area 201 and a second non-display area 202. The second display area 201 is also provided with a plurality of second light-emitting devices 212 arranged in an array, and the second non-display area 202 is also provided with a seventh trace 221. Each second light-emitting device 212 is connected to the seventh trace 221, and the seventh trace 221 is used to connect to the second trace 211 in another second display panel 20.
[0043] Among them, the fifth side 22 and the fourth side 21 are opposite sides.
[0044] It is understood that when a first display panel 10 and a second display panel 20 are spliced together as a first combined panel unit, each light-emitting device in the first display panel 10 is specifically connected to the driving control circuit through the second trace 211 in the second display panel 20. In order to connect each light-emitting device in the second display panel 20 to the driving control circuit, another second combined panel unit with only the second display panel 20 can be set up so that it can be connected to the driving control circuit through the seventh trace 221 and the second trace 211 in another second display panel 20 with the same circuit configuration. As needed, more second combined panel units can be spliced together to obtain a large-size spliced display panel 1. The second display panel 20 at the end of the splicing can also have a second trace 211 on its own back side, which will not be described in detail here.
[0045] This application also provides a display device; please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of one embodiment of the display device of this application. In this embodiment, the display device 30 specifically includes a housing 31 and a splicing display panel 32 connected together.
[0046] The splicing display panel 32 described in this embodiment is the splicing display panel 1 as described in any of the above embodiments. Please refer to [link / reference] for details. Figure 1 and Figure 2 The relevant textual explanations will not be repeated here.
[0047] Unlike existing technologies, the splicing display panel provided in this application includes a first display panel with adjacent first and second sides, and a first trace on the first side. The second display panel includes adjacent third and fourth sides, with the third side spliced to the second side and the fourth side facing away from the first side. The fourth side has a second trace connected to the first trace. This allows for minimizing the seam by placing the conductive leads used to connect to the driving control circuit on different panel units. It also effectively avoids the problems of asynchronous fabrication processes on opposite sides of the same panel unit, which can lead to a shift in the characteristics of the light-emitting devices, affecting the display, and the easy open circuit of the leads.
[0048] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
