Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] It should be understood that the terms "length", "width", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] It is important to know that with the continuous advancement of display technology, organic light-emitting diode (OLED) display technology has been widely used in high-end display fields such as smartphones, tablets, TVs and wearable devices due to its excellent color performance, wide viewing angle, fast response and thin and light design.

[0028] In the current pixel structure of OLED displays, the cathode signal line, as a crucial component for current transmission, is often limited by factors such as pixel density, screen size, and resolution. Due to the continuous increase in screen size and resolution, the cathode signal line inevitably needs to be designed to be longer to cover the entire display area. This long signal transmission path leads to a significant resistance voltage drop problem.

[0029] The voltage drop across the cathode signal line not only affects the uniformity of current distribution, leading to uneven screen brightness, but can also increase energy consumption and reduce display efficiency. This voltage drop issue is particularly pronounced during high-brightness displays or dynamic image displays, where increased current demand exacerbates the problem, severely impacting the display quality and user experience of OLED screens.

[0030] Based on this, the application improves the related display panel and display device.

[0031] Please see Figure 1 , Figure 1 This diagram shows a top view of the display panel provided in this embodiment. Figure 2 A partial cross-sectional view of the display panel provided in this embodiment is shown. This embodiment includes a substrate 100, a plurality of pixels 300, a first wiring structure 200, and a plurality of first connection structures 500; the plurality of pixels 300 are disposed on one side of the substrate 100, the plurality of pixels 300 are spaced apart on the display area 330, and a suspension structure 400 is provided between two adjacent pixels 300, the cathode 320 of the pixel 300 is attached to the suspension structure 400; the first wiring structure 200 surrounds at least a portion of the display area 330, and the first wiring structure 200 is used to receive cathode power signals; the plurality of first connection structures 500 are spaced apart along the extension direction of the first wiring structure 200, and the first wiring structure 200 is electrically connected to the suspension structure 400 through the first connection structures 500.

[0032] It should be explained that multiple pixels 300 are the basic units that make up the display image, and they are distributed at intervals on the surface of the display area 330. Each pixel 300 contains elements for emitting light (such as organic light-emitting diodes in OLEDs), and the light-emitting performance of these elements determines the color and brightness of the pixel 300.

[0033] The dangling structure 400 is disposed between two adjacent pixels 300, mainly serving to isolate different pixels 300. In this embodiment, the cathode 320 of the pixel 300 is also connected to these dangling structures 400, thereby realizing the transmission of the cathode power signal of the pixel 300. This design helps to simplify the wiring between pixels 300, improve the pixel density and display resolution. The composition and manufacturing process of the dangling structure 400 are described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and CN. Further descriptions are provided in CN117979755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, and CN117500332A for reference.

[0034] A first trace structure 200 surrounds at least a portion of the display area 330 and is used to receive cathode power signals. This arrangement allows multiple pixels 300 to be connected to the first trace structure 200 around the perimeter of the display area 330, thereby reducing the voltage drop of the cathode power signals.

[0035] In current display panels, a full-surface wiring structure is required, and the signal path from the wiring structure to the cathode 320 of pixel 300 is relatively long, resulting in a significant voltage drop. However, this application connects the cathode power signal through the first wiring structure 200 and transmits the cathode power signal to the cathode 320 of pixel 300 through the first connection structure 500 and the suspension structure 400. By setting the first connection structure 500 to directly connect the suspension structure 400 and the first wiring structure 200, the transmission path of the cathode power signal of pixel 300 near the connection area is shortened, thereby reducing the voltage drop of the cathode power signal of pixel 300.

[0036] Please refer to some embodiments of this application. Figure 2 In this embodiment, along the thickness direction a of the display panel, the first wiring structure 200 is disposed on the side of the suspension structure 400 near the substrate 100. The first wiring structure 200 is disposed on the side of the suspension structure 400 near the substrate 100, and it serves as a bridge for electrical connection, enabling the transmission of power signals to each pixel 300.

[0037] In other embodiments, the first wiring structure 200 may also be located on the side of the overhang structure 400 away from the substrate 100.

[0038] Please refer to some embodiments of this application. Figure 2 In this embodiment, the first wiring structure 200 and the anode 310 of the pixel 300 are set on the same layer.

[0039] In some embodiments, the anode 310 of the pixel 300 may include a metal oxide, a metal, or a multilayer material composite. For example, the anode 310 is ITO / Ag / ITO. The pixel 300 circuit supplies power to the anode 310 for display control.

[0040] In other embodiments, please refer to Figure 3 , Figure 3 A schematic diagram of the display panel provided in this embodiment is shown. In this embodiment, the first trace structure 200 can also be disposed on the side of the anode 310 of the pixel 300 near the substrate 100. That is, the first trace structure 200 is not disposed on the same layer as the anode 310, but on the same layer as the metal layer below the anode 310.

[0041] In some other embodiments, a portion of the first trace structure 200 is disposed on the same layer as the anode 310, and a portion is disposed on the side of the anode 310 near the substrate 100. Specifically, the first trace structure 200 can alternately trace on the layer where the anode 310 is located and on the layer where the anode 310 is near the substrate 100. Alternatively, the first trace structure 200 can overlap on the layer where the anode 310 is located and on the layer where the anode 310 is near the substrate 100, and the parallel arrangement of the two portions helps to reduce the resistance of the first trace structure 200.

[0042] For some embodiments of this application, please refer to Figure 4 , Figure 4 A schematic diagram of the structure of the display panel provided in this embodiment is shown. The display panel in this embodiment also includes a pixel definition layer 510. At least a portion of the pixel definition layer 510 is disposed between the first wiring structure 200 and the overhang structure 400. A first via 520 is provided on the pixel definition layer 510. At least a portion of the first connection structure 500 is disposed in the first via 520 and contacts the first wiring structure 200 and the overhang structure 400 respectively.

[0043] It should be explained that the pixel definition layer 510 is mainly used to define the boundary of each pixel 300, ensuring electrical and optical isolation between pixels 300, while providing the necessary support and connection structures. The first via 520 allows the first connection structure 500 to pass through, so that current or signals can be transmitted from the first trace structure 200 to the overhang structure 400, thereby realizing the transmission of the cathode power signal.

[0044] In some embodiments, please refer to Figure 5 , Figure 5A schematic diagram of the display panel provided in this embodiment is shown. The display panel of this embodiment includes a drive signal line 700, and the first via 520 is offset from the drive signal line 700 in the thickness direction a of the display panel; this helps to reduce signal interference between the drive signal line 700 and the signal path of the cathode 320. The drive signal line 700 can be electrically connected to the gate drive circuit.

[0045] In some embodiments, the pixel definition layer 510 is made of an insulating material, preferably a Si-based inorganic material such as SiO or SiN; it protects the anode 310 and prevents the anode 310 from oxidation.

[0046] In some embodiments, please continue reading Figure 5 In this embodiment, along the direction away from the substrate 100, the suspension structure 400 includes a first film layer 410, a second film layer 420, and a third film layer 430 stacked together. The orthographic projection of the second film layer 420 onto the substrate 100 lies within the orthographic projection of the third film layer 430 onto the substrate 100. The first connecting structure 500 is integrally formed with the first film layer 410. The material of the first film layer 410 may include molybdenum, the material of the second film layer 420 may include aluminum, and the material of the third film layer 430 may include titanium.

[0047] Please refer to some embodiments of this application. Figure 5 At least part of the first connecting structure 500 is disposed in the same layer as the anode 310.

[0048] For some embodiments of this application, please refer to Figure 6 , Figure 6 A schematic diagram of the structure of the display panel provided in this embodiment is shown. In this embodiment, along the extension direction of the first trace structure 200, the first trace structure 200 includes alternating first sub-segments 210 and second sub-segments 220. The first sub-segment 210 is disposed on the same layer as the anode 310 of the pixel 300, and the second sub-segment 220 is located on the side of the anode 310 layer close to the substrate 100.

[0049] In some embodiments, please refer to Figure 7 , Figure 7 A schematic diagram of the display panel provided in this embodiment is shown. In this embodiment, the first wiring structure 200 includes a third sub-segment 230 and a fourth sub-segment 240 that are arranged vertically overlappingly, and the third sub-segment 230 and the fourth sub-segment 240 are arranged in parallel.

[0050] In other words, the cathode power signal can be transmitted not only through the layer containing the anode 310, but also through the structural layer on one side of the anode 310, achieving double-sided signal transmission, which improves the speed and efficiency of signal transmission. This is particularly important for display panels that require high-speed data transmission. Furthermore, by providing redundant signal transmission paths, the double-sided signal transmission structure reduces the risk of signal interruption due to a single-path failure, thereby improving signal stability. Simultaneously, the double-sided signal transmission structure helps achieve a more uniform current distribution and lower resistance voltage drop, thus improving the efficiency and stability of electrical connections.

[0051] In some embodiments of this application, please refer to Figure 8 , Figure 8 A partial cross-sectional view of the display panel provided in this embodiment is shown. When the first trace structure 200 is connected to the cathode power signal, the cathode power signal flows along the first trace structure 200, the first connection structure 500, and the dangling structure 400 to the cathode 320 of the pixel 300. The drive signal line 700 is located at the bezel 600, and the dangling structure 400 and the pixel 300 are located in the display area 330.

[0052] In some embodiments, pixel 300 may include an anode 310, a light-emitting layer 340, a cathode 320, and a first encapsulation layer 350 arranged sequentially from bottom to top.

[0053] In some embodiments, the light-emitting layer 340 is an EL (Electroluminescence) film, and the cathode 320 is made of materials such as MgAg alloy. The first encapsulation layer 350 is an encapsulation structure that can isolate moisture and protect the light-emitting layer 340. The first encapsulation layer 350 is preferably made of inorganic materials such as SiO and SiN, and can be a CVD (Chemical Vapor Deposition) film; such as Figure 9 In this embodiment, a second encapsulation layer 800 can also be added to the CVD film layer. The second encapsulation layer 800 can be an IJP structure (Ink Jet Printing) to form a multilayer material structure.

[0054] In some embodiments, please refer to Figure 9 A third encapsulation layer 900 can be set on the second encapsulation layer 800, and the third encapsulation layer 900 is a CVD film layer.

[0055] For some embodiments of this application, please refer to Figure 10 , Figure 10A schematic diagram of the structure of the display panel provided in this embodiment is shown. The display panel of this embodiment also includes a first conductive structure 1100, a second wiring structure 1200, and a plurality of second connection structures 1300. The first conductive structure 1100 is electrically connected to the anode 310 of the plurality of pixels 300, and the first conductive structure 1100 extends out of the display area 330. The second wiring structure 1200 surrounds at least a portion of the display area 330 and is used to receive the anode power signal. The plurality of second connection structures 1300 are spaced apart along the extension direction of the second wiring structure 1200, and the second wiring structure 1200 is electrically connected to the second connection structure 1300.

[0056] In some embodiments, the first wiring structure 200 and the second wiring structure 1200 are respectively disposed on both sides of the display area 330.

[0057] In some embodiments, please continue reading Figure 10 The suspension structure 400 and the first connecting structure 500 are arranged on the same layer. In some embodiments, the suspension structure 400 and the first wiring structure 200 are arranged on the same layer.

[0058] Please refer to some embodiments of this application. Figure 10 The second wiring structure 1200 and the suspension structure 400 are set on the same layer; In some embodiments, the first conductive structure 1100 is disposed on the side of the anode 310 near the substrate 100; In some embodiments, please refer to Figure 11 The first conductive structure 1100 of this embodiment includes a plurality of first conductive lines 1110 spaced apart along the column direction, and each first conductive line 1110 extends out of the display area 330 along the row direction; In some embodiments, please continue reading Figure 11 In this embodiment, the multiple second connection structures 1300 are electrically connected to the multiple first conductive lines 1110 in a one-to-one correspondence.

[0059] Please refer to some embodiments of this application. Figure 11 The first conductive structure 1100 in this embodiment also includes a plurality of second conductive lines 1120 spaced apart along the row direction, each second conductive line 1120 extending along the column direction, and the first conductive line 1110 and the second conductive line 1120 are arranged to cross each other. In some embodiments, please refer to Figure 12 In this embodiment, each second conductive line 1120 extends out of the display area 330 along the column direction, and the end of the second conductive line 1120 is electrically connected to the second wiring structure 1200 through the second connection structure 1300. In some embodiments, please continue reading Figure 12In this embodiment, both ends of the first conductive line 1110 extend out of the display area 330, and both ends of the second conductive line 1120 extend out of the display area 330. The two ends of each first conductive line 1110 are electrically connected to the second wiring structure 1200 through two second connection structures 1300, and the two ends of each second conductive line 1120 are electrically connected to the second wiring structure 1200 through two second connection structures 1300.

[0060] For some embodiments of this application, please refer to Figure 13 In this embodiment, the loop path of the first wiring structure 200 includes multiple corners, and the first connecting structure 500 is located at at least one corner position on the loop path of the first wiring structure 200.

[0061] It should be explained that placing the first via 520 at the corner of the path of the first trace structure 200 helps to avoid the drive signal line 700, thereby reducing signal interference between the drive signal line 700 and the first via 520; and on the other hand, it also helps to reduce the size of the bezel 600 of the display panel.

[0062] In one exemplary description, the display area 330 has a rectangular structure, and the first wiring structure 200 surrounds the display area 330 to form a rectangular ring structure. The first via 520 can be preferably set at the corner of the rectangular ring structure.

[0063] Please refer to the embodiments described in this application. Figure 12 In this embodiment, there are multiple first vias 520, and the multiple first vias 520 are spaced apart along the circumferential direction of the first trace structure 200.

[0064] It should be explained that by arranging the first vias 520 at intervals along the circumferential direction of the first trace structure 200, a uniform current distribution during transmission can be ensured. This helps reduce localized overheating and electrical stress concentration, thereby enhancing the electrical stability of the display panel. Since the first vias 520 directly affect the light-emitting performance of the pixels 300, their layout has a significant impact on display performance. Multiple spaced first vias 520 ensure that more pixels 300 can receive a stable and uniform current supply, thereby improving display uniformity and color saturation, and thus contributing to high-quality image display.

[0065] In some embodiments, the number and spacing of the first vias 520 can be adjusted to flexibly adapt to different design requirements. For example, for pixel areas with a large cathode power signal voltage drop, the number of first vias 520 can be increased or the spacing can be decreased in that pixel area; while for pixel areas with a small cathode power signal voltage drop, the number of first vias 520 can be decreased or the spacing can be increased accordingly.

[0066] Furthermore, in order to better implement the display panel in any of the above embodiments, this application also provides a display device based on the above display panel, the display device including the above display panel.

[0067] In some embodiments, the display panel is an OLED display panel.

Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and corrections to this application.
