Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] This section is intended to provide background or context for the embodiments set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] Currently, for mass-produced display panels (PNLs), the bonding area length for bonding FPCs (Flexible Printed Circuits) is the same, meaning that multiple FPCs bonded to the PNL simultaneously are of the same specification. Conventional designs, to ensure these multiple FPCs are of the same specification, inevitably require many dummy pins on some FPCs. As touch transceiver configurations in display panels, such as 1T1R (single transmit / receive), single transmit / dual receive (1T2R), 2T2R (dual transmit / dual receive), and 2T1R (dual transmit / single receive), become more widespread in display products, the number of PNL pins is constantly increasing. If existing mass production methods are still used, the spacing between FPCs will be too narrow, causing PNL wrinkling during the bonding process of multiple FPCs, and even failing to meet basic bonding process requirements. Therefore, improving the PNL wrinkling problem is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The following is an overview of the subject matter described in detail in this disclosure. This overview is not intended to limit the scope of the claims.

[0005] This disclosure provides a display panel and a display device.

[0006] A first aspect of this disclosure provides a display panel including a non-display area extending along a first direction, and a plurality of bonding areas spaced apart along the extension direction of the non-display area, wherein the plurality of bonding areas are bonded to a plurality of flexible circuit boards, wherein at least some of the flexible circuit boards correspond to bonding areas of different lengths.

[0007] In some exemplary embodiments, the distance between at least two partially adjacent binding areas among the plurality of binding areas is different.

[0008] In some exemplary embodiments, the display panel further includes a display area, the display area being provided with a touch layer, the touch layer having a plurality of touch signal lines distributed thereon, the plurality of touch signal lines being connected to two binding areas located at both ends of the non-display area, wherein the plurality of signal lines include transmitting signal lines and receiving signal lines.

[0009] In some exemplary embodiments, the display panel further includes a driving circuit layer having gate driving signal lines distributed thereon, the gate driving signal lines being connected to two bonding regions located at both ends of the non-display area.

[0010] In some exemplary embodiments, the signal pins for connecting the touch signal line and the gate drive signal line in the bonding area located at both ends of the non-display area are symmetrically distributed.

[0011] In some exemplary embodiments, the display panel further includes control display signal lines connected to all the bonding areas, the control signal lines including lines for transmitting signals for controlling the display areas to display.

[0012] In some exemplary embodiments, the signal used to control the display area to display includes at least one of the following signals: a data signal line, a high-voltage power supply line, and a low-voltage power supply line.

[0013] In some exemplary embodiments, the width of the two binding areas located at both ends of the non-display area is greater than the length of any one of the binding areas located between the two ends of the non-display area.

[0014] In some exemplary embodiments, the width of the first signal pin used to connect the control display signal line in at least a portion of the plurality of bonding areas is greater than the width of the second signal pin used to connect other signal lines.

[0015] A second aspect of this disclosure provides a display device comprising a display panel as described in the first aspect.

[0016] In the display panel and display device provided in this disclosure, because bonding areas of different lengths are designed in the display panel, the spacing between multiple bonding areas can be unequally distributed within the limited space of the non-display area, thereby freeing up more space by increasing the spacing between the bonding areas. At the same time, the length of the bonding area of ​​the corresponding flexible circuit board can be effectively reduced, so that the specifications of the flexible circuit boards are different. Therefore, the spacing between the bonded flexible circuit boards can also be different, thereby freeing up more space. This solves the PNL Bonding wrinkling problem caused by the display panel bonding multiple FPCs, improves the bonding yield of the product, and improves the product yield of the display device.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this disclosure can be arbitrarily combined with each other. The present disclosure will be further described below with reference to the embodiments shown in the accompanying drawings.

[0025] like Figure 1The diagram illustrates an exemplary display panel in the related art. The display panel can have a multi-layer structure, for example, it may include a substrate, a driving circuit layer, a light-emitting layer, an encapsulation layer, and a touch layer. The touch layer includes touch traces. Typically, the transmit signal line TX and the receive signal line RX are located in the touch layer, while other signal lines, such as the gate drive signal line GOA, can be located in the driving circuit layer. For the touch signal lines and gate drive signal lines, a 2T1R routing configuration is used. The gate drive signal line GOA and the transmit signal line TX are led out from the left and right sides of the display panel, respectively, and connected to the left and right sides of the first flexible circuit board FPC1 and the fourth flexible circuit board FPC4, respectively. The receive signal RX is connected to the right side of the first flexible circuit board FPC1, the left side of the second flexible circuit board FPC2, the right side of the third flexible circuit board FPC3, and the left side of the fourth flexible circuit board FPC4, respectively. Since the four FPCs in this scheme have the same specifications, the number of pins bonded to the four FPCs is also the same. To ensure that multiple FPCs have identical specifications, dummy pins must be used on the right side of the first flexible circuit board FPC1 and the left side of the fourth flexible circuit board FPC4 to compensate for the difference between the gate drive signal line GOA and the emitter signal line TX. Similarly, dummy pins also need to be added to the left and right sides of the second flexible circuit board FPC2 and the third flexible circuit board FPC3. It is evident that each FPC in this related technology has unnecessary dummy pins, resulting in a relatively long FPC width, increased trace pressure, and further compression of the spacing between FPCs, causing PNL wrinkling problems during the bonding process.

[0026] An exemplary embodiment of this disclosure provides a display panel, such as... Figure 2 As shown, Figure 2 A schematic diagram of the structure of a display panel provided according to an exemplary embodiment of the present disclosure is shown below, in conjunction with... Figures 3-5 The display panel is described below. In this embodiment... Figures 2 to 5 These are partial schematic diagrams of the display panel; other structures within the display panel are not shown.

[0027] The display panel in this embodiment can be a flexible OLED display panel, a liquid crystal display panel, an LED / LCD, etc. This embodiment imposes limitations on the display panel. The size of the display panel can be medium-sized, such as a display panel of 8 to 14 inches or smaller. This embodiment does not impose specific limitations on the size of the display panel.

[0028] like Figure 2As shown, an exemplary embodiment of this disclosure provides a display panel 100, which includes a non-display area 110 extending along a first direction X. A plurality of bonding areas are spaced apart along the extension direction of the non-display area 110, and the plurality of bonding areas are bonded to a plurality of flexible circuit boards. At least some of the flexible circuit boards have different widths of the bonding areas.

[0029] like Figure 2 As shown, the multiple bonding areas of the display panel 100 typically correspond one-to-one with the bonding areas of the flexible circuit boards that need to be bonded subsequently. Therefore, during the design phase of the display panel 100, the length of the multiple bonding areas on the display panel 100 used for bonding the flexible circuit boards can correspondingly determine the length of the bonding areas of the flexible circuit boards, and the length of the bonding areas of the flexible circuit boards can determine the length of the flexible circuit boards. Therefore, the dimensions of the multiple bonding areas of the display panel 100 can be designed during the design phase of the display panel 100 to improve the length of the flexible circuit boards. In this embodiment, the multiple bonding areas used for bonding the multiple flexible circuit boards, such as the first bonding area 111, the second bonding area 112, the third bonding area 113, the fourth bonding area 114, the fifth bonding area 115, and the sixth bonding area 116, are distributed in the area of ​​the non-display area 110 of the display panel 100. The non-display area 110 can extend along the first direction X of the display panel 100 and can be located on one side of the display panel 100.

[0030] like Figure 2 As shown, an exemplary distribution of six bonding areas in the non-display area is illustrated. The bonding areas are the first bonding area 111, the second bonding area 112, the third bonding area 113, the fourth bonding area 114, the fifth bonding area 115, and the sixth bonding area 116. The multiple bonding areas are arranged at intervals along the extension direction (first direction X) of the non-display area 110. The length dimensions of some bonding areas can be different, while the length dimensions of some bonding areas can be the same. This allows the bonding areas with different length dimensions to be distributed with a larger spacing within the non-display area 110, thereby increasing the spacing between the bonding areas and freeing up more space. This solves the PNL Bonding wrinkle problem caused by the arrangement of FPCs in traditional mass production solutions during the bonding process.

[0031] like Figure 2 As shown, in the design scheme for distributing multiple binding areas, since the lengths of the multiple binding areas can be different, the spacing between the binding areas can be unequally distributed within the limited non-display area. For example, the distance between at least some of the adjacent binding areas can be different. Figure 2As shown, the first binding area 111 and the sixth binding area 116 are located at opposite ends of the non-display area, while the remaining binding areas are located between the first binding area 111 and the sixth binding area 116. The distances between any two adjacent binding areas can be either all different or partially the same. For example, as... Figure 2 As shown, the first width W1 between the first binding area 111 and the second binding area 112 is greater than the second width W2 between the second binding area 112 and the third binding area 113.

[0032] refer to Figure 3 As shown, an exemplary structural diagram of the flexible circuit board (FPC) after being bonded is illustrated. The first bonding area 111 corresponds to the bonding of the first flexible circuit board (FPC1), the second bonding area 112 corresponds to the bonding of the second flexible circuit board (FPC2), the third bonding area 113 corresponds to the bonding of the third flexible circuit board (FPC3), the fourth bonding area 114 corresponds to the bonding of the fourth flexible circuit board (FPC), the fifth bonding area 115 corresponds to the bonding of the fifth flexible circuit board (FPC5), and the sixth bonding area 116 corresponds to the bonding of the sixth flexible circuit board (FPC6). For example, as... Figure 3 As shown, the third width W3 between the first flexible circuit board FPC1 and the second flexible circuit board FPC2 is greater than the fourth width W4 between the second flexible circuit board FPC2 and the third flexible circuit board FPC3. The first width W1 can be the same as the third width W3, and the second width W2 can be the same as the fourth width W4. It is evident that because the display panel 100 is designed with bonding areas of different lengths, the length of the bonding area of ​​the bonded flexible circuit boards is effectively reduced. This allows for different specifications of the flexible circuit boards, and therefore, different spacing between the bonded flexible circuit boards, freeing up more space. This solves the problem of PNL Bonding wrinkles caused by the display panel 100 when bonding multiple FPCs, improving the bonding yield of the product.

[0033] To achieve different bonding region lengths, the design can be improved by reducing some unnecessary padding pins within the bonding region. (Reference) Figure 2 As shown, the display panel 100 also includes a display area 120, within which a display layer for display is disposed. The display area 120 is adjacent to the non-display area 110. A touch layer 130 and a driving circuit layer 140 can be disposed above the display area 120 and the non-display area 110. The touch layer 130 is a layer structure for touch signal routing, and the driving circuit layer 140 is a layer structure for driving signal routing. When there are multiple signal lines, the multiple signal lines can be routed through the touch layer 130 and the driving circuit layer 140 respectively, and led out through vias (not shown in the figure) to multiple required bonding areas, which are located on the same layer.

[0034] refer to Figure 2As shown, an exemplary schematic diagram of signal lines in the touch layer 130 and the driving circuit layer 140 is illustrated. Touch signal lines are distributed in the touch layer 130, including transmit signal lines TX and receive signal lines RX. Gate drive signal lines GOA are distributed in the driving circuit layer 140. Figure 2 As shown, two gate drive signal lines GOA are symmetrically arranged at both ends of the display panel 100 in the first direction X. The two gate drive signal lines GOA, led from the drive circuit layer 140, are connected to the leftmost side of the first bonding area 111 and the rightmost side of the sixth bonding area 116, respectively. A transmit signal line TX and a receive signal line RX, led from the touch layer 130, are also connected to the first bonding area 111 and the sixth bonding area 116, respectively. Specifically, the transmit signal line TX connected to the first bonding area 111 is adjacent to the gate drive signal line GOA connected to the first bonding area 111, located to the right of GOA. The receive signal line RX connected to the first bonding area 111 is adjacent to the transmit signal line TX connected to the first bonding area 111, located to the right of TX. The transmit signal line TX connected to the sixth bonding area 116 is adjacent to the gate drive signal line GOA connected to the sixth bonding area 116, located to the right of GOA. The receive signal line RX connected to the sixth bonding area 116 is positioned adjacent to the transmit signal line TX connected to the sixth bonding area 116, located to the left of the transmit signal line TX. The signal pins used to connect multiple signal lines in the first bonding area 111 and the sixth bonding area 116 are symmetrically distributed to prevent multiple signal lines from crossing when connecting the first bonding area 111 and the sixth bonding area 116. Figure 2 As shown, the signal lines connecting the first bonding region 111, from left to right, are the gate drive signal line GOA, the transmit signal line TX, and the receive signal line RX. The signal lines connecting the sixth bonding region 116, from right to left, are the gate drive signal line GOA, the transmit signal line TX, and the receive signal line RX.

[0035] In this embodiment, multiple signal lines led out from the touch layer 130 and the driving circuit layer 140 are centrally connected to the first binding area 111 and the sixth binding area 116 located at both ends of the non-display area 110, so as to centrally transmit multiple signal lines using the first binding area 111 and the sixth binding area 116, thereby reducing the length of other binding areas located between the two ends of the non-display area 110 and freeing up the spatial distance between two adjacent binding areas.

[0036] refer to Figure 2As shown, the signal traces distributed in the display panel also include control display signal lines 150. The control display signal lines 150 can be distributed in the driving circuit layer 140. The control display signal lines 150 can include lines for transmitting signals for controlling the display area 120 to display. The signals for controlling the display area 120 to display include at least one of the following signals: data signal lines, high-voltage power lines, and low-voltage power lines.

[0037] refer to Figure 2 and Figure 3 As shown, the control display signal line 150 is connected to all the bonding areas, that is, the control display signal line 150 is connected to the first bonding area 111, the second bonding area 112, the third bonding area 113, the fourth bonding area 114, the fifth bonding area 115, and the sixth bonding area 116 respectively, so as to transmit corresponding signals for controlling the display area 120 to be displayed to the first flexible circuit board FPC1, the second flexible circuit board FPC2, the third flexible circuit board FPC3, the fourth flexible circuit board FPC4, the fifth flexible circuit board FPC5, and the sixth flexible circuit board FPC6 that are bonded. The signals for controlling the display area 120 to be displayed can be triggered by the touch structure on the display panel 100, or they can be emitted by the control chip of the display panel 100; no specific limitation is made here.

[0038] refer to Figure 2 As shown, since multiple signal lines are respectively connected to the first bonding area 111 and the sixth bonding area 116 located at both ends of the non-display area 110, the length of the first bonding area 111 and / or the sixth bonding area 116 can both be greater than the length of any bonding area located between the first bonding area 111 and the sixth bonding area 116. This provides a larger spacing between the bonding areas distributed in the middle of the non-display area 110, thereby freeing up more space to solve the PNL Bonding wrinkle problem caused by the process of bonding multiple FPCs in the display panel 100, and improving the bonding yield of the product.

[0039] Another embodiment of this disclosure also provides a display panel that is substantially the same as the aforementioned embodiment, with the main difference being that the width of the signal pins used for connecting the control display signal line 150 in at least some of the multiple bonding areas is greater than the width of the signal pins used for connecting other signal lines. The display panel provided in another embodiment of this disclosure will be described below with reference to the accompanying drawings. It should be noted that the same or corresponding parts as those in the aforementioned embodiments can be referred to the corresponding descriptions in the aforementioned embodiments, and will not be repeated hereafter.

[0040] refer to Figure 2 and Figure 4As shown, the control display signal line 150 can be connected to all bonding areas on the display panel 100. Therefore, each bonding area is provided with multiple first signal pins 101 connected to the control display signal line 150. Figure 2 and Figure 4 As shown, the explanation uses the signal pins of the first bonding area 111 as an example. Exemplarily, the first signal pins 101 used to connect the control display signal line 150 are distributed in the middle of this bonding area, denoted as the first region 10. Since the control display signal line 150 contains a large number of signals, it also contains a large number of signal lines, and therefore, there are a large number of first signal pins 101 corresponding to the first region 10. To avoid the first signal pins 101 being concentrated in a small space, which would prevent the narrow space from meeting the routing requirements, the width of a single first signal pin 101 can be appropriately increased, and multiple first signal pins 101 can be arranged to spread outwards to expand the bonding space of the control display signal line 150, thus solving the problem of insufficient routing space for the control display signal line 150.

[0041] At the same time, in order to ensure that the overall length of the bonding area remains unchanged, the width of the second signal pin used to connect other signal lines can be appropriately reduced. For example... Figure 4 As shown, the second signal pins in the first bonding area 111, used to connect other signal lines such as the gate drive signal line GOA, the transmit signal line TX, and the receive signal line RX, are distributed on both sides of the first region 10 where the first signal pin 101 is located, and are respectively denoted as the second region 20 and the third region 30. For example, if the second signal pin located in the second region 20 is used to connect the gate drive signal line GOA and the transmit signal line TX, and the second signal pin located in the third region 30 is used to connect the receive signal line RX, then the width of the second signal pins located in the second region 20 and / or the third region 30 can be smaller than the width of the signal pins used to connect the control display signal line 150, thereby avoiding the problem of PNL wrinkles caused by excessive bonding area length.

[0042] Specifically, exemplarily Figure 5 for Figure 4 A magnified view of area A in the middle. Combined with... Figure 4 and Figure 5 As shown, in the first binding area 111, the area to the left of the first area 10 is the second area 20. The second signal pin 201 in the second area 20 is a pin used to connect to the control display signal line 150. The first signal pin 101 in the first area 10 is a pin used to connect to the control display signal line 150. The width dimension D1 of the first signal pin 101 is greater than the width dimension D2 of the second signal pin 201.

[0043] Another embodiment of this disclosure also provides a display panel that is substantially the same as the foregoing embodiments, with the main differences including: [reference needed] Figure 6 As shown, the display panel 100 also includes a PCB (Printed Circuit Board) 200, with multiple flexible circuit boards connected to the PCB 200. In this embodiment, for example, a display panel needs to be installed on some communication chassis panels to indicate the operating status of the device. The display panel 100 and the PCB board can be connected through multiple flexible circuit boards to transmit signals between the display area 120 and the PCB board 200.

[0044] Another embodiment of this disclosure also provides a display device, see reference. Figure 2 The display device includes the display panel 100 provided in the above embodiments. Because the display panel is designed with bonding areas of different lengths, the spacing between multiple bonding areas can be unequally distributed within the limited space of the non-display area 110. This allows bonding areas of different lengths to be distributed with greater spacing within the non-display area 110, thereby increasing the spacing between the bonding areas and freeing up more space. This solves the PNL Bonding wrinkling problem in the bonding process. Simultaneously, it can effectively reduce the length of the bonding areas of multiple bonded flexible circuit boards, allowing for different specifications of the flexible circuit boards. Therefore, the spacing between the bonded flexible circuit boards is also different, freeing up more space and solving the PNL Bonding wrinkling problem caused by the display panel 100 during the bonding of multiple FPCs. This improves the bonding yield of the product and the overall product yield of the display device.
