Description

Technical Field

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

[0002] LED (light-emitting diode) display technology is considered a new generation of display technology due to its high contrast, high brightness, low power consumption, long lifespan, wide operating temperature range, and short response time.

[0003] To achieve large-screen displays, existing LED display technology requires splicing smaller screens together. To minimize screen bezels and achieve seamless splicing, current technology typically employs side-wiring, directing circuitry to the back. However, during the splicing process, if two displays are too close together, the side-wiring on both sides can easily come into contact or collide, causing damage or breakage to the side-wiring or substrate. Summary of the Invention

[0004] The main technical problem addressed by this application is to provide a display panel and splicing display device that protects the side traces and substrate, thus ensuring seamless splicing.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a display panel, including a substrate, a wiring layer, and a support member. The substrate includes a first surface and a second surface disposed opposite to each other, and a side surface connecting the first surface and the second surface. The first surface and the second surface are respectively provided with a first conductor and a second conductor. The wiring layer includes multiple side traces, which protrude from the side surface and extend to the first surface and the second surface at both ends, respectively, to electrically connect the first conductor and the second conductor. The support member protrudes from the side surface, wherein the height of the support member protruding from the side surface is greater than the height of the side traces protruding from the side surface, and the orthographic projection of the support member on the side surface is located between the orthographic projections of two adjacent side traces on the side surface.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a splicing display device, including at least two display panels spliced ​​together as described in any embodiment.

[0007] The beneficial effects of this application are as follows: Unlike the prior art, the display panel of this application is provided with a support member that protrudes from the side of the side wiring at least on the side. During splicing, the support member can abut against the substrate or support member of the adjacent display panel to provide support. This makes it difficult for the side wiring of the display panel to directly contact the side wiring and substrate of the adjacent display panel, which can effectively protect the side wiring and prevent substrate damage caused by substrate collision during splicing. At the same time, the spacing between the support member and the side wiring can avoid damage to the side wiring when forming the support member. Attached Figure Description

[0019] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of one embodiment of the display panel of this application. Figure 2 This application Figure 1 A top view. (e.g.) Figure 1 As shown, the display panel includes a substrate 1, a wiring layer 2, and a support member 3. The substrate 1 includes a first surface 1a and a second surface 1b disposed opposite to each other, and a side surface 1c connecting the first surface 1a and the second surface 1b. The first surface 1a and the second surface 1b are respectively provided with a first conductor 11 and a second conductor 12. Specifically, a driving circuit (not shown) for connecting light-emitting devices can be disposed on the first surface 1a and the second surface 1b of the substrate 1.

[0021] The wiring layer 2 includes multiple side traces 21. The side traces 21 protrude from the side 1c and extend to the first surface 1a and the second surface 1b at both ends, respectively, to electrically connect the first conductor 11 and the second conductor 12. Specifically, the multiple side traces 21 can be formed simultaneously. The driving circuits on the first surface 1a and the second surface 1b are connected to the side traces 21 through the first conductor 11 and the second conductor 12, respectively. The first conductor 11 and the second conductor 12 can be pads made of metal.

[0022] The support member 3 protrudes from the side surface 1c. Specifically, in this embodiment, one side of the support member 3 can be fitted against the side surface 1c; wherein, the height of the support member 3 protruding from the side surface 1c is greater than the height of the side trace 21 protruding from the side surface 1c, such as... Figure 2 As shown, the orthographic projection of the support member 3 on side 1c lies between the orthographic projections of two adjacent side traces 21 on side 1c. Optionally, there are multiple support members 3, with a support member 3 provided between any two adjacent side traces 21. Specifically, in Figure 2 In the Y direction, multiple support components 3 and side wiring 21 are alternately arranged.

[0023] This application utilizes side traces 21 to direct the circuitry from the first surface 1a of the substrate 1 to the back surface (i.e., the second surface 1a), thereby reducing the bezel width. When this display panel is spliced ​​with other display panels to form a larger display panel, the gaps between the panels are smaller, achieving seamless splicing and a better display effect. Furthermore, since the display panel has a support member 3 protruding from the side trace 21 at least on the side 1c, during splicing, the support member 3 can abut against the substrate 1 or the support member 3 of the adjacent display panel, providing support. This makes it difficult for the side trace 21 of the display panel to directly contact the side trace 21 and substrate 1 of the adjacent display panel, effectively protecting the side trace 21 and preventing substrate damage caused by collisions between substrates 1 during splicing. At the same time, the spaced arrangement of the support member 3 and the side trace 21 avoids contact with the side trace 21 during the formation of the support member 3, thus preventing damage. Since the two do not contact each other, there are no restrictions on the order of fabrication of the side trace 21 and the support member 3, making the fabrication method more flexible.

[0024] Specifically, the material of the support 3 may include curable materials such as organic adhesives and thermosetting resins. During preparation, organic adhesives are first deposited on the side 1c, and then multiple organic adhesive blocks are formed by etching, and then cured to form a support 3 with high rigidity.

[0025] See Figure 3 , Figure 3 This is a schematic diagram of one embodiment of the splicing display device of this application. The splicing display device is composed of multiple display panels spliced ​​together, and each display panel is... Figure 1 and Figure 2 The display panel shown will have one of ( Figure 3 The left-hand side display panel is defined as the first display panel 10. The substrate 1, side 1c of the substrate 1, wiring layer 2, side wiring 21, and support member 3 in the first display panel 10 are respectively defined as the first substrate 101, the first side 101c, the first wiring layer 102, the first side wiring 1021, and the first support member 103; the other display panel ( Figure 3 The right side of the middle section is defined as the second display panel 20. The substrate 1, the side 1c of the substrate 1, the wiring layer 2, the wiring and the support member 3 in the second display panel 20 are respectively defined as the second substrate 201, the second side 201c, the second wiring layer 202, the second side wiring 2021 and the second support member 203.

[0026] When the first display panel 10 and the second display panel 20 (along) Figure 3When spliced ​​together in the X direction, the first side 101c of the first substrate 101 and the second side 201c of the second substrate 201 are arranged in parallel. Specifically, the first side 101c and the second side 201c are arranged in the same direction, and the projections of multiple first side traces 1021 and multiple second side traces 2021 on the first side 101c coincide.

[0027] In this embodiment, the side trace 21 and the support member 3 can be provided only on one side 1c of the substrate 1. Figure 3 On the right side of the middle section, the first support member 103 of the first display panel 10 is abutting against the second substrate 201 of the second display panel 20. Since the height of the first support member 103 in the X direction is greater than the height of the first side trace 1021, the first side trace 1021 and the first substrate 101 are less likely to collide with the second substrate 201, thereby reducing the probability of damage to the first side trace 1021 and the two substrates.

[0028] In other embodiments, the side traces 21 and the support members 3 may be disposed on multiple sides 1c of the substrate 1. The orthographic projections of multiple first side traces 1021 and multiple second side traces 2021 on the first side 101c may also partially overlap or not overlap.

[0029] See Figure 4 , Figure 4 This is a schematic diagram of another embodiment of the display panel of this application. In this embodiment, the support member 3 is attached to the side 1c, and in the thickness direction ( Figure 4 The height of the support member 3 protruding from the first surface 1a in the Z direction is greater than the height of the side trace 21 protruding from the first surface 1a; and in the thickness direction ( Figure 4 In the opposite direction of the Z-direction, the height of the support member 3 protruding from the second surface 1b is greater than the height of the side wiring 21 protruding from the second surface 1b. Since the support member 3 is higher than the side wiring 21 in the thickness direction, even if displacement occurs in the thickness direction during splicing, the upper and lower surfaces of the side wiring 21 are less likely to collide, further reducing the probability of damage to the side wiring 21.

[0030] In other embodiments, the support member 3 may protrude from the first surface 1a at a height greater than the side trace 21 protruding from the first surface 1a; or protrude from the second surface 1b at a height greater than the side trace 21 protruding from the second surface 1b.

[0031] See Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of another embodiment of the display panel of this application. Figure 6This is a top view of another embodiment of the display panel of this application. A portion of the support member 3 extends to the first surface 1a and the second surface 1b. Specifically, the support member 3 partially wraps around the side surface 1c and the portions of the first surface 1a and the second surface 1b connected to the side surface 1c. This increases the contact area between the support member 3 and the substrate 1, making it less likely for the support member 3 to detach from the substrate 1. In this embodiment, the height of the support member 3 protruding from both the first surface 1a and the second surface 1b is higher than that of the side trace 21, and the support member 3 can protect a larger area of ​​the side trace 21. Figure 6 As shown, a set of opposite side surfaces 1c in the X direction are provided with spaced-apart side traces 21 and spaced-apart support members 3, wherein the orthographic projections of the side traces 21 on both sides of the side surface 1c coincide, and the orthographic projections of the support members 3 on both sides of the side surface 1c also coincide. Of course, in other embodiments, the support members 3 may also be lower than the side traces 21 in the thickness direction.

[0032] See Figure 7 , Figure 7 This is a schematic diagram of another embodiment of the display panel of this application. The display panel also includes a protective layer 4 covering the wiring layer 2, wherein a support member 3 is disposed on the side of the protective layer 4 facing away from the substrate 1. Specifically, the protective layer 4 covers a plurality of side wirings 21 and the substrate 1 between the side wirings 21. The protective layer 4 can be formed after the side wirings 21 are formed, and is used to isolate water and oxygen and protect the side wirings 21; the support member 3 can be formed after the protective layer 4. In other embodiments, the protective layer 4 may also cover the wiring layer 2 and the support member 3.

[0033] See Figure 8 , Figure 8 This is a schematic diagram of another embodiment of the splicing display device of this application. Both the first display panel 10 and the second display panel 20 are... Figure 5 and Figure 6 The display panel shown. When the first display panel 10 and the second display panel 20 (alongside) Figure 8 When the components are spliced ​​together in the X direction, the first side surface 101c of the first substrate 101 and the second side surface 201c of the second substrate 201 are positioned opposite each other, and multiple first side traces 1021 and multiple second side traces 2021 are positioned opposite each other. Multiple first support members 103 and multiple second support members 203 are positioned opposite each other. In this embodiment, the paired first support members 103 and second support members 203 abut against each other. Since the height of the first support member 103 in the X direction is greater than the height of the first side trace 1021, and the height of the second support member 203 in the X direction is greater than the height of the second side trace 2021, collisions are less likely to occur between the opposing first side traces 1021 and second side traces 2021, or between the first substrate 101 and the second substrate 201, thereby reducing the probability of damage between the side traces and between the substrates.

[0034] See Figure 9 , Figure 9 This is a schematic diagram of another embodiment of the splicing display device of this application. When the first display panel 10 and the second display panel 20 are spliced ​​together, the first support member 103 and the second support member 203 are spaced apart on the orthographic projection of the first side surface 101c. In this embodiment, in Figure 9 In the X-direction, the distance by which the first support member 103 protrudes above the first side panel 101c, or in the opposite direction of the X-direction, the distance by which the second support member 203 protrudes above the second side panel 201c, is greater than the sum of the distances by which the first side trace 1021 protrudes above the first side panel 101c and the second side trace 2021 protrudes above the second side panel 201c. Because the first support member 103 and the second support member 203 are staggered during splicing, the distance between two adjacent display panels can be shortened and the gap between display panels reduced, while ensuring that the side traces and the substrate are not damaged, thereby improving the display effect of the splicing display device. In this embodiment, the height of the first support member 103 and the height of the second support member 203 are the same. In other embodiments, their heights may be different. Therefore, the height of the support member with the higher height protruding from the side should be greater than the sum of the distances by which the first side trace 1021 protrudes above the first side panel 101c and the second side trace 2021 protrudes above the second side panel 201c, to ensure that the side traces and the substrate are not damaged.

[0035] Optionally, please continue reading Figure 9 The opposing sides of the first support member 103 and the second support member 203 are parallel to the splicing direction, and the two are fitted together. During splicing, the first support member 103 and the second support member 203 can be kept in a fitted state and move closer together in the X direction until the support member abuts against the substrate, thus avoiding displacement of the first display panel 10 and the second display panel 20 during and after splicing, improving the splicing effect and splicing efficiency.

[0036] It should be noted that, Figure 9 One of the display panels has a set of support members on a set of opposite sides, and the orthographic projections of the support members on the two sides are spaced apart on one of the sides.

[0037] See Figure 10 , Figure 10This is a schematic diagram of another embodiment of the splicing display device of this application. When the first display panel 10 and the second display panel 20 are spliced ​​together, the first support member 103 and the second support member 203 are inserted into each other. Specifically, the first support member 103 includes a first sub-support member 1031 and a second sub-support member 1032 spaced apart, and a slot 103a is formed between the first sub-support member 1031 and the second sub-support member 1032. The width of the slot 103a in the Y direction is the same as the width of the second support member 203 in the Y direction. During splicing, the second support member 203 can be kept in close contact with the side walls of the slot 103a and move closer in the X direction until the support member abuts against the substrate, avoiding displacement of the first display panel 10 and the second display panel 20 in the Y direction and its opposite direction during and after splicing, further improving the splicing effect and splicing efficiency, and the splicing stability is high due to the insertion of the two. In this embodiment, the orthographic projections of the first sub-support 1031, the second sub-support 1032, and the second support 203 onto the plane of the substrate are all rectangles of the same shape. Of course, in other embodiments, the slot can also be disposed on the second display panel, and the first support of the first display panel is inserted into the slot of the second display panel.

[0038] In other embodiments, the support member can be of other shapes. For example... Figure 11 As shown, Figure 11 This is a schematic diagram of another embodiment of the splicing display device of this application. The orthographic projection of the first sub-support 1031, the second sub-support 1032, and the second support 203 on the plane of the substrate is an isosceles trapezoid, and the width of the isosceles trapezoid gradually narrows away from the display panel. The slot 103a between the first sub-support 1031 and the second sub-support 1032 is an isosceles trapezoidal groove with a gradually increasing opening. During splicing, the second support 203 can be aligned with the slot 103a and moved closer in the X direction. Since the end width of the second support 203 is small, alignment is relatively convenient. As the two display panels move closer, the insertion of the second support 203 into the slot 103a becomes tighter and tighter until the first sub-support 1031 and the second sub-support 1032 abut against the second substrate 201, making the splicing display device more stable.

[0039] It should be noted that, Figure 10 and Figure 11 One of the display panels has a set of support members on a set of opposite sides, with multiple slots formed on one side and a support member with a shape that matches the slots on the other side.

[0040] Specifically, the splicing display device is a Micro-LED splicing display device. It can be a large-size Micro-LED splicing display screen, etc.

[0041] The above embodiments of the splicing display device only exemplify the splicing of two display panels. In other embodiments, splicing can also be performed in four directions (up, down, left, right) or more directions. The splicing method is as described above and will not be repeated here.

[0042] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes 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 scope of patent protection of this application.
