Abstract
Description
Technical Field
[0001] This invention relates to the field of display technology, and more particularly to a display panel and a display device. Background Technology
[0002] Among existing display products, such as Figure 1 The display panel shown has left and right bezels extending from the display area 01 to the non-display area 02. The non-display area 02 includes at least a shift register circuit area 03, a power signal trace area 04, a package area 05, and a cut line 06. Due to the narrow bezel design, the compression space for the shift register circuit area 03, power signal trace area 04, package area 05, and cut line 06 is approaching its limit, or even already has. However, users still have a demand for further narrow bezel designs in display products. Therefore, there is an urgent need to provide a design solution that can further achieve narrow bezel designs in display products. Summary of the Invention
[0003] In view of this, the present invention provides a display panel and a display device to further realize the narrow bezel design of display products.
[0004] In a first aspect, this application provides a display panel, comprising:
[0005] The non-display area includes a first non-display area and a second non-display area disposed opposite to each other along a first direction, and a third non-display area and a fourth non-display area disposed opposite to each other along a second direction; the first direction and the second direction intersect.
[0006] A first electrode connection structure is located at least in the third non-display area and / or the fourth non-display area;
[0007] A first region extends through the display panel along the first direction, and the first electrode connection structure is located outside the first region.
[0008] Secondly, based on the same inventive concept, this application provides a display device, which includes the display panel.
[0009] Compared with related technologies, the display panel and display device provided by the present invention achieve at least the following beneficial effects:
[0010] This application provides a display panel and a display device. Since the third and fourth non-display areas of the display panel have some areas where structural components can be added, this application sets the first electrode connection structure in the third and / or fourth non-display areas that are arranged opposite each other along the second direction. The first electrode connection structure is located outside the first area that penetrates the display panel along the first direction, so that the setting position of the first electrode connection structure avoids the first and second non-display areas in the display panel as much as possible. This realizes the utilization of the usable space in the third and / or fourth non-display areas, thereby saving the space required to set the structural components in the first and second non-display areas. This is beneficial to further reduce the space required in the first and second non-display areas of the display panel and further realize the design scheme of narrow bezel of display products.

Figure 3 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 4 The image shown is another top view of the display panel provided in an embodiment of this application. Please refer to... Figures 2-4 This application provides a display panel 100, including:
[0049] The non-display area 10 includes a first non-display area 11 and a second non-display area 12 arranged opposite each other along the first direction XX, and a third non-display area 13 and a fourth non-display area 14 arranged opposite each other along the second direction YY; the first direction XX and the second direction YY intersect.
[0050] The first electrode connection structure 30 is located at least in the third non-display area 13 and / or the fourth non-display area 14.
[0051] The first region 15 extends through the display panel 100 along the first direction XX, and the first electrode connection structure 30 is located outside the first region 15.
[0052] In related technologies, for example when the display panel is Figure 1 In the rectangular display panel shown, the non-display area 02 of the display panel is not used for displaying the image, but can be used to set up the circuits, components, etc. required to drive the display area 01 to display the image. The non-display area 02 may include a first non-display area and a second non-display area arranged opposite each other on both sides of the display area 01 along the first direction XX. The non-display area 02 may also include a third non-display area and a fourth non-display area arranged opposite each other along the second direction YY, wherein the first non-display area and the second non-display area can be used for, for example Figure 1 The shown layout includes shift register circuit area 03, power signal trace area 04, package area 05, cutting line 06, etc. The third and fourth non-display areas can be used to set up driver chips, flexible circuit boards, multiplexing circuits, electrostatic protection circuits, etc. Of course, this application is not limited to this; this is just one possible way to utilize the non-display area of the display panel provided by this application. Users can adjust the settings of related circuits and components in the non-display area of the display panel according to their own needs.
[0053] This application provides a display panel 100, which may include a display area 20 and a non-display area 10. One possible implementation is that the non-display area 10 may surround the display area 20. Taking a rectangular display panel 100 as an example, the non-display area 10 may include a first non-display area 11 and a second non-display area 12 disposed opposite each other on both sides of the display area 20 along a first direction XX, and a third non-display area 13 and a fourth non-display area 14 disposed opposite each other on both sides of the display area 20 along a second direction YY. Specifically, the first direction XX and the second direction YY may intersect perpendicularly. In this case, as... Figure 2 As shown, the first electrode connection structure 30 can be optionally placed in the third non-display area 13, or as... Figure 3 As shown, the first electrode connection structure 30 can be optionally positioned in the fourth non-display area 14, or as... Figure 4 As shown, a portion of the first electrode connection structure 30 can be optionally located in the third non-display area 13, and a portion of the first electrode connection structure 30 can be located in the fourth non-display area 14; since in related technologies, the corresponding first electrode connection structure 30 is located in the aforementioned background technology. Figure 1 The power signal trace area 04 shown, that is, the first electrode connection structure in the related technology, occupies the position of the non-display area 02 that is relatively arranged along the first direction XX in the display product, resulting in a large area occupied by the left and right bezels of the display product. For the display panel of the related technology, there is no room for compression of the left and right bezels, but some redundant space can still be squeezed out in the non-display area 02 that is relatively arranged along the second direction YY. Without increasing the area of the non-display area 10 that is relatively arranged along the second direction YY, there is still space to accommodate some other structural components. Therefore, as Figures 2-4 As shown, this application chooses to place at least a portion of the first electrode connection structure 30 into the third non-display area 13 and / or the fourth non-display area 14 disposed along the second direction YY, thereby reducing the space occupied by the power signal trace area 04 in the non-display area 02 along the first direction XX in the related art, so that the non-display area 10 of the display panel 100 along the first direction XX only includes Figure 1 The corresponding shift register circuit area 03, package area 05, and cutting line 06 section can be used, thereby reducing the required area of the non-display area 10 along the first direction XX, realizing further compression of the area of the non-display area 10 of the display panel 100, which is conducive to further realizing the narrow bezel design of the display panel 100.
[0054] Furthermore, the display panel 100 provided in this application includes a first region 15, which extends through the display panel 100 along a first direction XX. This first region 15 can be an area occupied by at least a portion of the display area 20 along the first direction XX, and a first non-display area 11 and a second non-display area 12 disposed outside the display area 20 along the first direction XX. Since, in related technologies, taking a rectangular display panel as an example, the top and bottom sides of the display panel can have some redundant space to add structural components, in order to reduce the area of the non-display areas corresponding to the left and right borders of the display panel, the first electrode connection structure 30 can be disposed outside the first region 15, without occupying the area of the left and right borders in the related technologies. Specifically, this reduces the area occupied by the corresponding power signal trace area 04 in the related technologies. Therefore, as... Figures 2-4 As shown, this application arranges the first electrode connection structure 30 in the third non-display area 13 and / or the fourth non-display area 14 of the display panel 100. This arrangement ensures that the area of the first electrode connection structure 30 is large enough to guarantee its function for transmitting electrical signals and meet the requirements for normal operation of the display panel 100. At the same time, it avoids the occupation of the area of the first non-display area 11 and / or the second non-display area 12 by the first electrode connection structure 30 in the display panel 100, thereby reducing the required area of the first non-display area 11 and / or the second non-display area 12 and further reducing the area of the non-display area 10 of the display panel 100. This is beneficial for further realizing the narrow bezel design of the display panel 100.
[0055] It should also be noted that, Figures 2-4 In the illustrated embodiment, the first electrode connection structure 30 occupies most of the area of the third non-display area 13 and / or the fourth non-display area 14. This is only one optional setting method provided by this application, and the application is not limited to this. Users can set the first electrode connection structure 30 to occupy only a part of the area of the third non-display area 13 and / or the fourth non-display area 14 according to their needs, as long as the first electrode connection structure 30 can maintain its original function and ensure the normal operation of the display panel 100.
[0056] It should also be noted that this application does not limit the number of microstructures included in the first electrode connection structure 30 included in the display panel 100. That is, the first electrode connection structure 30 can be composed of multiple microstructures as needed, or it can be set as an integral structure as needed. Users can make corresponding adjustments to the shape, type, number of microstructures, material and other physical properties of the first electrode connection structure 30 as needed.
[0057] It should also be noted that this application does not specifically limit the type of electrical signal used by the first electrode connection structure 30 to transmit in the display panel 100. Users can move the components originally set in the power signal trace area for transmitting a certain electrical signal to the redundant space in the third non-display area 13 and / or the fourth non-display area 14 as needed, as long as the required area of the first non-display area 11 and / or the second non-display area 12 can be reduced without increasing the area of the third non-display area 13 and the fourth non-display area 14, thereby compressing the overall non-display area 10 of the display panel 100.
[0058] Furthermore, it should be noted that the rectangular display panel 100 is used as an example in this application only to illustrate that the first electrode connection structure 30 in the display product can be moved to the redundant space in the non-display area 10, and is not intended to limit the technical solution of moving the first electrode connection structure 30 to the redundant space in the non-display area 10 provided in this application to be used only for the rectangular display panel 100. Figure 5 The image shown is another top view of the display panel provided in an embodiment of this application, for example... Figure 5 As shown, when the display panel 100 is a circular display panel 100, the non-display area 10 of the display panel 100 can also be divided into the first non-display area 11, the second non-display area 12, the third non-display area 13, and the fourth non-display area 14 along the intersecting first direction XX and second direction YY. For example, in related technologies, the first electrode connection structure was originally set in the first non-display area 11 and / or the second non-display area 12 of the circular display panel. In this application, the first electrode connection structure 30 can be moved to the redundant space in other non-display areas. For example, the first electrode connection structure 30 can be moved to the third non-display area 13 and / or the fourth non-display area 14, thereby achieving the reduction of the overall non-display area 10 of the display panel 100 in this application.
[0059] Figure 6 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 7 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 8 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 9 The image shown is another top view of the display panel provided in an embodiment of this application. Please refer to... Figures 6-9 Optionally, the non-display area 10 includes a corner area 16, and the first electrode connection structure 30 is at least partially located in the corner area 16.
[0060] It should be noted that in related technologies, the redundant space in the corner areas corresponding to the four corners of a rectangular display product is relatively large. Although the central area of the non-display area set along the second direction YY also has some space that can be compressed and utilized, this space is smaller than that of the corner areas. Therefore, the first electrode connection structure 30 can be set in at least one end of the third non-display area 13 along the first direction XX of the display panel 100, and / or the first electrode connection structure 30 can be set in at least one end of the fourth non-display area 14 along the first direction XX of the display panel 100. This setting not only reduces the non-display area of the left and right areas of the non-display area 10, but also avoids the increase in the manufacturing difficulty of the display panel 100 due to the small setting area of the first electrode connection structure 30 when it is set in the central area of the non-display area 10 set along the second direction YY. It can also avoid the increase in the difficulty of electrical connection stability between the first electrode connection structure 30 and other structural components, thereby ensuring the stability of electrical signal transmission required when the display panel 100 is working normally.
[0061] Therefore, taking a rounded rectangle display panel 100 as an example, the non-display area 10 will include four corner areas 16. As mentioned above, in the rounded rectangle display panel 100, compared with the four rectangular non-display areas corresponding to the top, bottom, left and right display areas 20 in the non-display area 10, the corner area 16 corresponding to the rounded corners has relatively more redundant space. Therefore, the first electrode connection structure 30 can be moved to the corner area 16, which can also reduce the space occupied by the power signal trace area in the non-display area along the first direction XX in the related technology, thereby reducing the required area size of the non-display area 10 along the first direction XX, realizing further compression of the area of the non-display area 10 of the display panel 100, which is conducive to further realizing the narrow bezel design of the display panel 100.
[0062] It should be noted that this application does not limit the requirement that a first electrode connection structure 30 be provided in every corner area 16. Users can allocate the number of corner areas 16 according to their needs. For example, when a rectangular display panel 100 includes four corner areas 16, such as... Figure 6 , Figure 7 As shown, one or two corner areas 16 can be selected for the setting of the first electrode connection structure 30, such as... Figure 8 , Figure 9 As shown, three or all of the corner areas 16 can also be selected for the setting of the first electrode connection structure 30.
[0063] Furthermore, this application uses a rounded rectangular non-display area 10 including four corner areas 16 as an example to illustrate the setting of the first electrode connection structure 30. This is only one optional embodiment provided by this application and is not intended to limit the technical solution provided by this application to only display panels 100 including rounded rectangles. For example, a right-angled rectangular display panel 100 can also use at least some of the corner areas 16 to set the first electrode connection structure 30. Similarly, other shaped display panels 100 can also use some corner areas 16 with redundant space to set the first electrode connection structure 30. As long as the location with redundant space in the non-display area 10 of the display panel 100 is used to set the first electrode connection structure 30, the area where the first electrode connection structure was originally set in the display panel of the related technology is avoided, so as to reduce the area occupied by the non-display area 10 of the display panel 100.
[0064] Figure 10 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 11 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 12 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 13 The image shown is another top view of the display panel provided in an embodiment of this application. Please refer to... Figures 2-4 and Figures 10-13 Optionally, the non-display area 10 includes a corner area 16 and a second area 17, the second area 17 connecting the two corner areas 16, and the first electrode connection structure 30 passing through the second area 17.
[0065] As mentioned above, in the related technologies, the first electrode connection structure occupies the position of the non-display area relatively arranged along the first direction XX in the display product, resulting in a large area occupied by the left and right bezels of the display product. For the display panels of the related technologies, there is no room for compression of the left and right bezels. However, some redundant space can still be squeezed out in the non-display area relatively arranged along the second direction YY. Without increasing the area of the non-display area relatively arranged along the second direction YY, there is still space to accommodate some other structural components. Therefore, this application also provides an alternative implementation method, such as... Figures 10-13As shown, taking a display panel 100 with rounded corners as an example, the non-display area 10 includes four corner areas 16. Along the first direction XX from the first non-display area 11 to the second non-display area 12, the non-display area 10 can optionally include a second area 17. This second area 17 can connect the two corner areas 16 set along the first direction XX. In this case, the first electrode connection structure 30 can optionally be set through at least the entire second area 17. That is, the first electrode connection structure 30 can be set using at least a portion of the third non-display area 13 and / or the fourth non-display area 14 in the display panel 100.
[0066] Specifically, such as Figures 10-13 As shown, the first electrode connection structure 30 can also be optionally located in at least one of the two corner regions 16 adjacent to the second region 17. Specifically, for example... Figure 10 As shown, the first electrode connection structure 30 can be optionally disposed in the second region 17 of the third non-display area 13 and in the corner region 16 facing the first non-display area 11, for example... Figure 11 As shown, the first electrode connection structure 30 may be optionally disposed in the second region 17 of the third non-display area 13 and in the corner region 16 facing the second non-display area 12. Similarly, as Figure 12 , Figure 13 As shown, the first electrode connection structure 30 can also be optionally located in the second region 17 of the fourth non-display area 14 and at least one adjacent corner region 16. Alternatively, the first electrode connection structure 30 can be located throughout the entire third non-display area 13 and / or the fourth non-display area 14, such as... Figure 2 As shown, the first electrode connection structure 30 can be optionally set in the entire third non-display area 13, such as... Figure 3 As shown, the first electrode connection structure 30 may be optionally located within the entire fourth non-display area 14, such as... Figure 4 As shown, it is possible to optionally position a portion of the first electrode connection structure 30 within the entire third non-display area 13 and a portion of the first electrode connection structure 30 within the entire fourth non-display area 14.
[0067] It should be noted that this application proposes that the first electrode connection structure 30 can be disposed through the second region 17, and does not limit the first electrode connection structure 30 to occupying only the second region 17. The first electrode connection structure 30 can also be further extended to at least one corner region 16 connected to the second region 17. In this way, the placement area of the first electrode connection structure 30 in the non-display area 10 can be increased. When other structural components are disposed to make electrical connections with the first electrode connection structure 30, the larger area of the first electrode connection structure 30 can improve the ease and stability of its electrical connection with other structural components. This ensures the role played by the first electrode connection structure 30 in the operation of the display panel 100 when it is disposed in the second region 17, or the second region 17 and the adjacent corner region 16. This achieves the goal of reducing the overall non-display area 10 of the display panel 100 while ensuring the normal operation of the display panel 100 and ensuring the use effect of the corresponding display device.
[0068] Figure 14 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 15 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 16 The image shown is another top view of the display panel provided in an embodiment of this application. Please refer to... Figures 14-16 Optionally, it also includes:
[0069] Display area 20, which includes a first electrode signal line 50 and a first electrode connection structure 30 electrically connected to the first electrode signal line 50.
[0070] This application provides an alternative implementation in which the display panel 100 further includes a display area 20. For example, a non-display area 10 may be optionally arranged around the display area 20. The display area 20 may be provided with a first electrode signal line 50, which may be electrically connected to a first electrode connection structure 30 to transmit electrical signals to the first electrode connection structure 30. When one end of the first electrode signal line 50 is electrically connected to the first electrode connection structure 30, the other end of the first electrode signal line 50 may be optionally electrically connected to a driver chip 51 corresponding to the display panel 100, so that the electrical signals emitted by the driver chip 51 can be transmitted to the first electrode connection structure 30 through the first electrode signal line 50.
[0071] It should be noted that this application does not limit the type of the first electrode signal line 50, nor does it limit the type of electrical signal transmitted by the first electrode signal line 50. Users can set the type of the first electrode signal line 50 and the type of electrical signal it transmits according to their needs.
[0072] A specific implementation method is provided here, wherein the first electrode signal line 50 may be a PVEE signal line, and the display panel 100 may include multiple PVEE signal lines. In this application, the PVEE signal lines may be arranged in the display area 20 to avoid the PVEE signal lines occupying space in the non-display area 10. Compared with the related technology, which arranges at least some of the PVEE signal lines through the first non-display area and the second non-display area along the first direction XX, this method can further save the area required for the wiring, components, etc. in the display panel 100 in the non-display area 10, thereby reducing the area of the first non-display area and the second non-display area along the first direction XX in the display panel. One end of a portion of the PVEE signal line can be electrically connected to the first electrode connection structure 30 to transmit electrical signals to the first electrode connection structure 30. The end of the PVEE signal line near the driver chip 51 can be electrically connected to the PVEE terminal in the driver chip 51 to receive negative power supply signals and transmit the signals. In this way, the PVEE signal line is used to transmit electrical signals (PVEE signals, power supply voltage signals) emitted by the driver chip 51 to the first electrode connection structure 30.
[0073] It should be noted that the PVEE mentioned in this application refers to Pixel VEE, where Pixel represents a pixel and VEE represents negative voltage. In other words, PVEE represents providing a negative voltage to a pixel.
[0074] Please refer to Figure 14 and Figure 16 Optionally, the first electrode connection structure 30 includes a plurality of sub-first electrode connection structures 31, with at least two sub-first electrode connection structures 31 connected in parallel.
[0075] This application provides an alternative implementation in which the first electrode connection structure 30 in the display panel 100 can be composed of two or more sub-first electrode connection structures 31. When the display panel 100 is provided with a plurality of sub-first electrode connection structures 31, at least two sub-first electrode connection structures 31 can be configured to be connected in parallel, which is beneficial to reduce the overall impedance of the first electrode connection structure 30, thereby reducing the load on the first electrode connection structure 30; it is also beneficial to improve the transmission effect of electrical signals related to the first electrode connection structure 30, thereby improving the display effect of the display panel 100.
[0076] Specifically, the aforementioned "two sub-first electrode connection structures 31 connected in parallel" is as follows: Figure 14As shown, the display panel 100 not only has a first electrode signal line 50 (shown in thick lines) for transmitting electrical signals from the driver chip 51 to the sub-first electrode connection structure 31, but the first electrode signal line 50 may also include multiple sub-first electrode signal lines 501 (shown in thin lines). By electrically connecting multiple first electrode signal lines 50 (including sub-first electrode signal lines 501) to each other, the parallel connection of multiple first electrode signal lines 50 (including sub-first electrode signal lines 501) is realized, thereby indirectly realizing the parallel connection relationship between the two sub-first electrode connection structures 31.
[0077] Please combine Figure 14 Reference Figure 16 ,like Figure 16 As shown, after the four sub-first electrode connection structures 31 are each connected to the signal line, the signal lines connected to these four sub-first electrode connection structures 31 are then electrically connected to the driver chip 51 through a common signal line. At this time, the transmission of electrical signals to the four sub-first electrode connection structures 31 can be achieved through a single signal terminal on the driver chip 51. Based on this, refer to... Figure 14 The illustrated embodiment, in Figure 16 Based on the first electrode signal line 50 shown, multiple sub-first electrode signal lines 501 (not shown) extending along the first direction XX and / or along the second direction YY are further provided, and multiple first electrode signal lines 50 (including sub-first electrode signal lines 501) are electrically connected to each other, thereby realizing the parallel connection of multiple first electrode signal lines 50 (including sub-first electrode signal lines 501) to indirectly realize the parallel connection relationship between the four sub-first electrode connection structures 31.
[0078] It should be added that, Figure 14 The sub-first electrode signal line 501 shown by the thin line can belong to the first electrode signal line 50 or be an added auxiliary signal line. This application does not specifically limit this, and users can choose to set it according to actual needs. Furthermore, it is possible to set the first electrode signal line 50 extending along the first direction XX and the first electrode signal line 50 extending along the second direction YY in the same layer, or it is possible to set the first electrode signal line 50 extending along the first direction XX and the first electrode signal line 50 extending along the second direction YY in different layers. The first electrode signal lines 50 in different layers can be connected by punching holes to achieve their parallel connection relationship. As for... Figure 14 The drawing of the thick and thin lines of the first electrode signal line is only used to illustrate how to realize the parallel connection relationship between multiple sub-first electrode connection structures 31, and is not used to limit the thickness of the first electrode signal line in the actual panel design. Users can select and set the physical properties of the first electrode signal line in the display panel according to actual needs.
[0079] Figure 17 The image shown is another top view of the display panel provided in an embodiment of this application. Please refer to the figure. Figure 15 and 17 Optionally, there are at least two first electrode signal lines 50 that are electrically connected to the first electrode connection structure 30.
[0080] This application provides an alternative implementation in which the display panel 100 includes at least two first electrode signal lines 50; for example, when the first electrode connection structures 30 are respectively disposed in the two corner areas 16 on both sides of the second region 17 along the first direction XX, such as... Figure 15 As shown, two corner areas 16 can be optionally set to be electrically connected to different first electrode signal lines 50 respectively, so that each first electrode signal line 50 can transmit electrical signals to the first electrode connection structure 30 set in a corner area 16 respectively. When required by the design, each first electrode connection structure 30 can be controlled separately to realize the diversified driving requirements of the display panel 100.
[0081] Furthermore, for example Figure 17 As shown, it is also possible to optionally set one first electrode connection structure 30 to be electrically connected to at least two first electrode signal lines 50 simultaneously. On the one hand, even if one of the first electrode signal lines 50 electrically connected to the first electrode connection structure 30 is disconnected, the other first electrode signal lines 50 can still transmit relevant electrical signals to the first electrode connection structure 30, avoiding the problem of some electrical signals not being transmitted in the display panel 100 and improving the yield of the display panel 100. On the other hand, setting the same first electrode connection structure 30 to be electrically connected to multiple first electrode signal lines 50 increases the number of first electrode signal lines 50 in the display panel 100, which also helps to reduce the overall impedance of the first electrode connection structure 30, thereby reducing the load on the first electrode connection structure 30 and improving the transmission effect of electrical signals related to the first electrode connection structure 30, thus improving the display effect of the display panel 100.
[0082] Figure 18 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 19 The image shown is provided in an embodiment of this application. Figure 18 Please refer to a cross-sectional view of EE'. Figure 18 and Figure 19 Optionally, it also includes:
[0083] The metal component 52 is disposed in a different layer from the first electrode signal line 50 along a direction perpendicular to the plane of the display panel 100, and the metal component 52 is connected in parallel with at least a portion of the first electrode signal line 50.
[0084] This application provides an alternative implementation in which the display panel 100 may further include a metal component 52. The metal component 52 and the first electrode signal line 50 may be disposed in different layers along a direction perpendicular to the plane of the display panel 100, and the metal component 52 and at least a portion of the first electrode signal line 50 are connected in parallel. This is equivalent to connecting the metal component 52 in parallel to the first electrode signal line 50, thereby reducing the overall impedance of the first electrode signal line 50, thereby reducing the load on the first electrode signal line 50, which is beneficial to improving the effect of the first electrode signal line 50 in transmitting electrical signals, thereby further improving the display effect of the display panel 100.
[0085] A specific implementation method is provided here, such as... Figure 18 , Figure 19 As shown, corresponding metal parts 52 can be disposed in different layers at at least some positions of the first electrode signal lines 50. For example, the metal parts 52 can be selectively disposed in a certain film layer of the first electrode signal lines 50 facing the light-emitting surface of the display panel 100. It can be further selectively disposed that the metal parts 52 are electrically connected to the corresponding first electrode signal lines 50 through the connecting vias 521, so as to realize the parallel connection of some first electrode signal lines 50 and metal parts 52. In this way, it is equivalent to connecting conductive structural components in parallel to at least some of the first electrode signal lines 50 on the display panel 100, thereby reducing the impedance of the corresponding first electrode signal lines 50, which helps to reduce the voltage drop on the first electrode signal lines 50 in the display panel 100, thereby helping to improve the uniformity of the display brightness of the display panel 100 and improving the user's visual experience.
[0086] Alternatively, the metal part 52 can be placed in a film layer of the film layer structure where the first electrode signal line 50 is located, away from the light-emitting surface of the display panel 100. Then, the metal part 52 can be electrically connected to the corresponding first electrode signal line 50 through the connecting via. This can also achieve a structure in which part of the first electrode signal line 50 and the metal part 52 are connected in parallel, thereby improving the user's visual experience.
[0087] It should also be noted that this application does not limit the thickness, width, or length of the metal part 52. Users can select the thickness, width, length, and other physical conditions of the metal part 52 connected in parallel with the first electrode signal line 50 according to the wiring space in the display panel 100 and the need to reduce impedance, so as to achieve the best effect of reducing the voltage drop of the display panel 100.
[0088] It should be noted that connecting the metal part 52 in parallel to the first electrode signal line 50 is only one way to reduce the load of the first electrode signal line 50 provided in this application. Alternatively, the load of the first electrode signal line 50 can be reduced by increasing the line width of at least a portion of the first electrode signal line 50 along the second direction YY and / or along the first direction XX. Alternatively, the load of the first electrode signal line 50 can be reduced by increasing the thickness of at least a portion of the first electrode signal line 50 along the direction perpendicular to the plane of the display panel 100. Alternatively, the load of the first electrode signal line 50 can be reduced by using a low-impedance material to make the first electrode signal line 50.
[0089] It should be noted that any one of the five methods provided in this application—increasing the number of first electrode signal lines 50, connecting metal parts 52 in parallel with the first electrode signal lines 50, increasing the line width of the first electrode signal lines 50, increasing the thickness of the first electrode signal lines 50, or using low-impedance materials to fabricate the first electrode signal lines 50—can reduce the load on the first electrode signal lines 50. Users can choose to use any two, three, or four of the above five methods to reduce the load on the first electrode signal lines 50. Furthermore, when conditions permit, users can also choose to use all five methods simultaneously to reduce the load on the first electrode signal lines 50, thereby reducing its impact on the electrical signals transmitted between the first electrode connection structures 30 and ensuring a good display effect for the display panel 100.
[0090] Figure 20 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 21 The image shown is provided in an embodiment of this application. Figure 20 Please refer to a cross-sectional view of AA'. Figure 20 and Figure 21 Optionally, it also includes:
[0091] Display area 20, first electrode 40, the first electrode 40 is located in display area 20 and at least part of non-display area 10;
[0092] The first electrode 40 and the first electrode connection structure 30 are disposed in different layers;
[0093] The first electrode connection structure 30 includes a plurality of sub-first electrode connection structures 31. The first electrode 40 and the sub-first electrode connection structures 31 are electrically connected through a first via 41 along a direction perpendicular to the plane of the display panel 100.
[0094] This application provides an alternative implementation in which the display panel 100 further includes a display area 20. For example, a non-display area 10 may be optionally arranged to surround the display area 20. At the same time, the display panel 100 may also include a first electrode 40. For example, the first electrode 40 may be optionally arranged to be located in the display area 20 and extend at least partially into the non-display area 10.
[0095] At this time, the display panel 100 is also provided with a first electrode connection structure 30. The first electrode connection structure 30 can be optionally composed of two or more sub-first electrode connection structures 31, wherein the sub-first electrode connection structures 31 are all disposed on the same layer. Alternatively, the first electrode 40 and the first electrode connection structure 30 can be disposed on different layers. Furthermore, along a direction perpendicular to the light-emitting surface of the display panel 100, some sub-first electrode connection structures 31 and their corresponding first electrodes 40 can have a partial overlap area. Further, an electrical connection between the first electrode 40 and the sub-first electrode connection structures 31 with overlapping areas can be achieved through a first via 41 disposed along the direction perpendicular to the light-emitting surface of the display panel 100. An insulating layer 42 can be filled between the first electrode 40 and the sub-first electrode connection structures 31 to avoid crosstalk between electrical signals.
[0096] It should be added that, taking the display panel 100 provided in this application as an OLED display panel as an example, the non-display area of the OLED display panel is provided with a PVEE overlap structure and a cathode that are electrically connected to the PVEE signal lines. The OLED display panel needs to have this PVEE overlap structure connected to the cathode so that the power supply voltage signal transmitted by the PVEE signal lines can be transmitted to the cathode through the PVEE overlap structure; for example... Figure 21 As shown, the OLED display panel includes multiple light-emitting elements 94. Along a direction perpendicular to the plane of the display panel 100, each light-emitting element 94 may include an anode 942, a light-emitting layer 941, and a cathode (40) stacked sequentially. The first electrode 40 mentioned in this application can be electrically connected to the cathode (40) corresponding to the light-emitting element 94 of the OLED display panel on the same layer. Specifically, the cathode (40) of the light-emitting element 94 can extend into the non-display area 10 to realize the setting of the first electrode 40. Therefore, as... Figure 21 As shown, by setting the first electrode 40 and the first electrode connection structure 30 (sub-first electrode connection structure 31) to be electrically connected through the first via 41, this application can realize the transmission of the electrical signal transmitted by the first electrode signal line 50 to the first electrode 40 (cathode of the light-emitting element 94) through the first electrode connection structure 30 to which it is electrically connected, so that the electrical signal can be used to regulate whether the light-emitting element 94 is in the light-emitting state.
[0097] This application establishes an electrical connection between the first electrode 40 and the first electrode connection structure 31 in the non-display area 10 by connecting the first electrode 40 and a portion of the first electrode connection structure 31 through a first via 41. This allows for the transmission of electrical signals from the first electrode 40 to the first electrode 40 via the first electrode connection structure 30. Compared to related technologies, this arrangement places the first electrode connection structure 30, used for transmitting electrical signals to the first electrode 40, in the third non-display area 13 and / or the fourth non-display area 14. Figure 20 As shown, the first electrode connection structure 30 can be mostly located in the corner area 16 corresponding to the third non-display area 13 and / or the fourth non-display area 14. This helps to reduce the area occupied by the electrical connection between the first electrode connection structure 30 and the first electrode 40 in the non-display area 10 of the display panel 100. That is, by utilizing part of the third non-display area 13 and / or the fourth non-display area 14 with redundant space for the connection between the first electrode connection structure 30 and the first electrode 40, the area occupied by the first electrode connection structure and the area (power signal trace area 04) originally set in the display panel of the related technology is avoided. This reduces the space required for the first non-display area 11 and the second non-display area 12 of the corresponding display panel 100, and achieves the narrow bezel requirement of the display panel 100.
[0098] It should be noted that, Figure 21A schematic diagram of the film layer structure of the display panel 100 is shown. Specifically, the display panel 100 may include a substrate 91, an array layer 92, and a light-emitting layer 93. In addition, the display panel may also include an encapsulation layer (not shown) located on the side of the light-emitting layer 93 away from the substrate 91. The light-emitting element 94 may include an anode 942, a light-emitting layer 941, and a cathode (40) stacked in sequence. The light-emitting layer 941 and the cathode (40) may be disposed in sequence on the side of the anode 942 away from the substrate 91. When the power supply provides an appropriate voltage, the holes of the anode 942 and the electrons of the cathode (40) will combine in the light-emitting layer 941 to generate light. In addition, the side of the substrate 91 facing the light-emitting layer 93 may also include a poly (active layer), a first metal layer M1, a second metal layer M2, a third metal layer M3, a fourth metal layer M4, and a pixel definition layer PDL. A first insulating film 951 may be disposed between the poly (active layer) and the first metal layer M1. A second insulating film 952 and a third insulating film 953 may be disposed between the first metal layer M1 and the second metal layer M2. A fourth insulating film 954 may be disposed between the second metal layer M2 and the third metal layer M3. A fifth insulating film 955 may be disposed between the third metal layer M3 and the fourth metal layer M4. A sixth insulating film 956 may be disposed between the fourth metal layer M4 and the anode 942. The insulating film can be used to avoid crosstalk between electrical signals transmitted by adjacent film layers. It can also make the surface of the insulating film away from the substrate 91 have a flat surface, which is more suitable for the placement of other film layers on the side of the insulating film away from the substrate 91.
[0099] It should be noted that this application is attached with Figure 21 This is merely an example of a cross-sectional view of an OLED display panel to illustrate an embodiment in which the cathode (40) of the light-emitting element 94 of this application extends into the non-display area to form the first electrode 40. Users can also adjust the specific film structure of the display panel according to their own needs; in addition, the attached... Figure 21 Taking the first electrode connection structure 30 as an example, which is located on the side of the cathode (40) away from the substrate 91, this application is not limited to this. Users can also set the first electrode connection structure 30 in a certain film layer structure on the side of the cathode (40) facing the substrate 91, as long as the electrical signal received by the first electrode connection structure 30 can be transmitted to the cathode (40).
[0100] Figure 22 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 23 The image shown is provided in an embodiment of this application. Figure 22 A cross-sectional view of BB', please refer to... Figure 20 , Figure 21 Reference Figure 22 and Figure 23 Optionally, it also includes:
[0101] Display area 20, first electrode 40, the first electrode 40 is located in display area 20 and at least part of non-display area 10;
[0102] The first medium 60 is at least partially located in the non-display area 10;
[0103] The first electrode 40, the first electrode connection structure 30, and the first dielectric 60 are all disposed in different layers;
[0104] The first electrode connection structure 30 includes a plurality of sub-first electrode connection structures 31. Along the direction perpendicular to the plane of the display panel 100, the first medium 60 and the first electrode 40 include a first overlapping region C1, and the first medium 60 and at least one sub-first electrode connection structure 31 include a second overlapping region C2.
[0105] The first electrode 40 and the first dielectric 60 are electrically connected in the first overlapping region C1 through the second via 44, and the sub-first electrode connection structure 31 and the first dielectric 60 are electrically connected in the second overlapping region C2 through the third via 43.
[0106] This application also provides an alternative implementation in which the display panel 100 further includes a display area 20, for example, a non-display area 10 may be optionally arranged to surround the display area 20. At the same time, the display panel 100 may also include a first electrode 40, for example, the first electrode 40 may be optionally arranged to be located in the display area 20 and extend at least partially into the non-display area 10.
[0107] It should be added that, taking the display panel 100 provided in this application as an OLED display panel as an example, the non-display area of the OLED display panel is provided with a PVEE overlap structure and a cathode that are electrically connected to the PVEE signal lines. The OLED display panel needs to have this PVEE overlap structure connected to the cathode so that the power supply voltage signal transmitted by the PVEE signal lines can be transmitted to the cathode of the OLED display panel through the PVEE overlap structure; please refer to... Figure 21The OLED display panel includes multiple light-emitting elements 94. Along the direction perpendicular to the plane of the display panel 100, the light-emitting element 94 may include an anode 942, a light-emitting layer 941, and a cathode (40) stacked in sequence. The first electrode 40 mentioned in this application may be disposed in the same layer as the cathode (40) corresponding to the light-emitting element 94 of the OLED display panel. Specifically, the cathode (40) of the light-emitting element 94 may extend to the non-display area 10 to realize the setting of the first electrode 40. Therefore, by setting the electrical connection between the first electrode 40 and the first electrode connection structure 30, this application can realize the transmission of the electrical signal transmitted by the first electrode signal line 50 to the first electrode 40 (cathode of the light-emitting element 94) through the first electrode connection structure 30 to which it is electrically connected, so that the electrical signal can be used to control whether the light-emitting element 94 is in the light-emitting state. Furthermore, since the film thickness of a cathode is generally set to be relatively thin, when the film thickness of a cathode is set to be relatively thin, an additional electrical signal transmission medium can be added, such as the first medium 60 mentioned in this application. The first medium 60 serves as a relay station for the transmission of electrical signals between the cathode and the PVEE overlap structure, in order to avoid the situation where the overlap stability between the cathode and the PVEE overlap structure may be poor when the cathode film thickness is very thin. The addition of the first medium 60 is used to improve the overlap stability of the cathode and the PVEE overlap structure, thereby ensuring the transmission effect of electrical signals between the cathode and the PVEE overlap structure.
[0108] That is, this application can electrically connect one end of the first electrode connection structure 30 to the first electrode signal line 50, electrically connect the other end of the first electrode signal line 50 to the driver chip 51, connect the first electrode connection structure 30 to the first medium 60, and connect the first medium 60 to the first electrode 40, thereby realizing the transmission of the electrical signal received by the first electrode signal line 50 from the driver chip 51 to the first electrode 40 through the first electrode connection structure 30 and the first medium 60. For example, specifically, it can realize the transmission of PVEE signal to the cathode of the light-emitting element in the display panel, so as to realize the adjustment of whether the light-emitting element is in the display state.
[0109] Specifically, such as Figure 22 and Figure 23As shown, this application provides a specific embodiment in which a first electrode connection structure 30 is simultaneously provided in the display panel 100. The first electrode connection structure 30 can optionally be composed of two or more sub-first electrode connection structures 31, wherein the sub-first electrode connection structures 31 can all be arranged in the same layer. Simultaneously, a first medium 60 can optionally be provided in the display panel 100, the first medium 60 being at least partially located in the non-display area 10. In this case, the first electrode 40, the first electrode connection structure 30, and the first medium 60 can optionally be arranged in different layers. Further, along a direction perpendicular to the plane of the display panel 100, the first medium 60 and the first electrode 40 can be provided to include a first overlapping area C1. The first medium 60 and the first electrode 40 can be connected in the first overlapping area C1 by a second via 44 arranged along a direction perpendicular to the light-emitting surface of the display panel 100. The electrical connection between the first electrodes 40, and along the direction perpendicular to the plane of the display panel 100, can be provided with a second overlapping region C2 between the first dielectric 60 and at least one sub-first electrode connection structure 31. The electrical connection between the first dielectric 60 and the first electrode connection structure 30 can be achieved in the second overlapping region C2 through a third via 43 disposed along the direction perpendicular to the light-emitting surface of the display panel 100. Specifically, along the direction perpendicular to the plane of the display panel 100, the first dielectric 60 can be located between the first electrode connection structure 30 and the first electrode 40. The electrical connection between the first electrode 40 and the first dielectric 60 is achieved through a second via 44, and the electrical connection between the first dielectric 60 and the first electrode connection structure 30 is achieved through a third via 43. That is, the electrical connection between the first electrode 40 and the first electrode connection structure 30 is achieved through the first dielectric 60 as an intermediate transition. An insulating layer 42 can be filled between the first electrode 40 and the first dielectric 60, and between the sub-first electrode connection structure 31 and the first dielectric 60, to avoid crosstalk between electrical signals. By setting a first dielectric 60 as a bridge structure between the first electrode 40 and the first electrode connection structure 31, the design freedom for realizing the electrical connection relationship between the first electrode 40 and the first electrode connection structure 30 is improved.
[0110] In this embodiment, a first medium 60 is provided as a transition structure for the electrical connection between the first electrode 40 and a portion of the first electrode connection structure 31. The second via 44 and the third via 43 are combined to realize the electrical connection between the first electrode 40 and the first electrode connection structure 30 in the non-display area 10, so as to realize the transmission of electrical signals from the first electrode connection structure 30 to the first electrode 40. With this configuration, the first electrode connection structure 30, used to transmit electrical signals to the first electrode 40, is located in the third non-display area 13 and / or the fourth non-display area 14. This helps to reduce the area occupied by the electrical connection between the first electrode connection structure 30 and the first electrode 40 in the non-display area 10 of the display panel 100. In other words, by utilizing the third non-display area 13 and / or the fourth non-display area 14, which have some redundant space, the connection between the first electrode connection structure 30 and the first electrode 40 is avoided, thereby reducing the space required for the first non-display area 11 and the second non-display area 12 of the corresponding display panel 100.
[0111] Furthermore, it should be noted that the light-emitting element 94 included in the display panel 100 may have a structure including an anode 942, a light-emitting layer 941, and a cathode (40) stacked sequentially along the direction perpendicular to the plane of the display panel 100. In this case, the first medium 60 located in the non-display area 10 may be formed by extending the anode 942 film layer in the non-display area 10, but the first medium 60 is insulated from the anode 942, that is, the first medium 60 and the anode 942 may be made of the same layer and the same material; the first electrode 40 located in the non-display area 10 may be formed by extending the cathode to the non-display area 10, that is, the first electrode 40 and the cathode may be made of the same layer and the same material. Such a configuration can simplify the manufacturing process of the display panel 100, reduce the manufacturing time of the display panel 100, and improve the manufacturing efficiency of the display panel 100. Of course, this is only one possible implementation of the first dielectric 60 and the first electrode 40 provided in this application. Users can also adjust the film position and manufacturing process of the first dielectric 60 and the first electrode 40 in the display panel 100 according to actual needs.
[0112] Figure 24 The image shown is another top view of the display panel provided in an embodiment of this application. Figure 25 The image shown is provided in an embodiment of this application. Figure 24 A cross-sectional view of DD', please refer to... Figure 20 Reference Figure 24 and Figure 25 Optionally, the first overlapping region C1 and the second overlapping region C2 do not overlap in the direction perpendicular to the plane of the display panel 100.
[0113] This application provides an alternative implementation in which, when the display panel 100 is provided with the first electrode 40, the first dielectric 60, and the first electrode connection structure 30 arranged in different layers as described above, along the direction perpendicular to the plane of the display panel 100, the first dielectric 60 and the first electrode 40 include a first overlapping region C1, and the first dielectric 60 and the first electrode connection structure 30 include a second overlapping region C2. In this case, along the direction perpendicular to the plane of the display panel 100, the first overlapping region C1 and the second overlapping region C2 can be optionally set to not overlap, thereby improving the design freedom of realizing the electrical connection relationship between the first electrode 40 and the first electrode connection structure 30, and at the same time ensuring the normal operation of the display panel 100 while reducing the overall area of the non-display area 10 of the display panel 100.
[0114] Please combine Figure 20 Reference Figure 22 and Figure 23 Optionally, along a direction perpendicular to the plane where the display panel 100 is located, the first overlapping region C1 and the second overlapping region C2 include at least a partial overlapping area.
[0115] This application provides an alternative implementation where, when the display panel 100 is provided with the first electrode 40, the first dielectric 60, and the first electrode connection structure 30 arranged in different layers as described above, along a direction perpendicular to the plane of the display panel 100, the first dielectric 60 and the first electrode 40 include a first overlapping region C1, and the first dielectric 60 and the first electrode connection structure 30 include a second overlapping region C2. In this case, along a direction perpendicular to the plane of the display panel 100, the first overlapping region C1 and the second overlapping region C2 can optionally be configured to have an overlapping area. This can further reduce the space occupied by the first overlapping area C1 and the second overlapping area C2 in the non-display area 10, thereby avoiding excessive occupation of the non-display area 10 by setting the first electrode 40, the first medium 60, the first electrode connection structure 30 and realizing the electrical connection between them. It is beneficial to further compress the area of the remaining non-display areas 10 on the basis of reducing the area required for the first non-display area 11 and the second non-display area 12 of the display panel 100, while ensuring good transmission of electrical signals in the display panel 100 and ensuring the display effect of the corresponding display device.
[0116] It should be noted that the first overlapping area C1 and the second overlapping area C2 mentioned above are set in the third non-display area 13 and / or the fourth non-display area 14. They can be set in the corner area 16 corresponding to the third non-display area 13 and / or the fourth non-display area 14. The first overlapping area C1 and the second overlapping area C2 have overlapping areas in the direction perpendicular to the plane of the display panel 100. This helps to reduce the area occupied by the electrical connection between the first electrode connection structure 30, the first medium 60 and the first electrode 40 in the non-display area 10 of the display panel 100. That is, by using part of the third non-display area 13 and / or the fourth non-display area 14 with redundant space for the connection of the first electrode connection structure 30, the first medium 60 and the first electrode 40, the occupation of the relevant connection areas of the first electrode connection structure 30, the first medium 60 and the first electrode 40 in the display panel of the related technology is avoided, thereby reducing the area required for the left and right bezel areas of the display panel.
[0117] Figure 26 The image shown is an enlarged view of a corner area provided in an embodiment of this application. Please refer to it. Figure 6 and Figure 26 Optionally, along a direction perpendicular to the plane of the display panel 100, the first electrode 40 and at least one sub-first electrode connection structure 31 include a third overlapping region C3.
[0118] Along the extension direction of the third overlapping region C3, the third overlapping region C3 includes at least the first sub-region C31 and the second sub-region C32;
[0119] Along the extension direction perpendicular to the third overlapping region C3, the width of the first sub-region C31 is different from the width of the second sub-region C32.
[0120] This application provides an alternative implementation in which, when the display panel 100 includes a first electrode 40 and a first electrode connection structure 30 disposed in different layers, the first electrode connection structure 30 may be composed of multiple sub-first electrode connection structures 31, and at least one sub-first electrode connection structure 31 is electrically connected to the first electrode 40 to realize the electrical connection relationship between the first electrode connection structure 30 and the first electrode 40. In this case, along the direction perpendicular to the plane where the display panel 100 is located, a third overlapping region C3 may be provided between the sub-first electrode connection structure 31 and the first electrode 40. Based on this, this application provides an alternative implementation in which, along the direction surrounding the display area 20, the third overlapping region C3 may be divided into at least a first sub-region C31 and a second sub-region C32, wherein, along the direction perpendicular to the direction surrounding the display area 20, the width of the first sub-region C31 and the width of the second sub-region C32 may be different.
[0121] Taking the third overlapping region C3 as a corner region 16 as an example, the third overlapping region C3 may include a first sub-region C31 and a second sub-region C32. The first sub-region C31 is located in the central region of the corner region 16, and the second sub-region C32 is located in the corner region 16 on the side facing the third non-display region 13. Based on related technologies, the corner region can also provide redundant space for structural components. The redundant space in the central region of the corner region is the most abundant. Therefore, the first electrode 40 and the second sub-region C32 can be set according to the size trend of the redundant space in the non-display region 10. The electrical connection position of the first electrode connection structure 30 ensures that the electrical connection between the first electrode 40 and the first electrode connection structure 30 makes full and accurate use of the redundant space in the non-display area in the related technology, thereby avoiding the occupation of the connection area of the first electrode connection structure 30 and the first electrode 40 in the display panel of the related technology. This arrangement can reduce the space required for the non-display area 10 of the display panel 100, and realize the electrical connection relationship between the structural components in the display panel 100, ensuring the good operation of the display panel 100.
[0122] Figure 27 The image shown is another enlarged view of the corner area provided in an embodiment of this application. Please refer to... Figure 6 and Figure 27 Optionally, along a direction perpendicular to the plane of the display panel 100, the first electrode 40 and at least one sub-first electrode connection structure 31 include a third overlapping region C3.
[0123] Along the extension direction of the third overlapping region C3, the width of the third overlapping region C3 gradually increases, at least in part, along the extension direction perpendicular to the third overlapping region C3.
[0124] This application provides an alternative implementation in which, when the display panel 100 includes a first electrode 40 and a first electrode connection structure 30 disposed in different layers, the first electrode connection structure 30 may be composed of multiple sub-first electrode connection structures 31, and at least one sub-first electrode connection structure 31 is electrically connected to the first electrode 40 to realize the electrical connection relationship between the first electrode connection structure 30 and the first electrode 40. In this case, along the direction perpendicular to the plane where the display panel 100 is located, a third overlapping region C3 may be provided between the sub-first electrode connection structure 31 and the first electrode 40. Based on this, this application provides an alternative implementation in which the width of the third overlapping region C3 gradually increases along the direction surrounding the display area 20.
[0125] Taking the third overlapping region C3 as a corner region 16 as an example, the third overlapping region C3 may include a first sub-region C31 and a second sub-region C32. The first sub-region C31 is located in the central region of the corner region 16, and the second sub-region C32 is located in the corner region 16 on the side facing the third non-display region 13. Based on related technologies, the corner region can also provide redundant space for structural components. The redundant space in the central region of the corner region is the most abundant. Therefore, the redundant space corresponding to the corner region 16 exhibits a situation where the width of the redundant space increases along the direction from the first sub-region C31 to the second sub-region C32. Therefore, the first electrode can be set according to the size trend of the redundant space in the non-display region 10. The electrical connection position of the first electrode 40 and the first electrode connection structure 30, that is, along the extension direction of the third overlapping region C3, is provided such that at least part of the width of the third overlapping region C3 gradually increases along the extension direction perpendicular to the third overlapping region C3. This allows the electrical connection between the first electrode 40 and the first electrode connection structure 30 to make full and accurate use of the redundant space of the non-display area 10 in the related technology, thereby occupying the connection area of the first electrode connection structure 30 and the first electrode 40 originally provided in the display panel of the related technology. This can both reduce the space required for the non-display area 10 of the display panel 100 and realize the electrical connection relationship between the structural components in the display panel 100, ensuring the good operation of the display panel 100.
[0126] Figure 28 The image shown is another enlarged view of the corner area provided in an embodiment of this application. Figure 29 The image shown is another enlarged view of the corner area provided in an embodiment of this application. Please refer to... Figure 22 and Figure 28 , Figure 29 Optionally, it includes a display area 20;
[0127] Along the direction from the display area 20 to the non-display area 10, the non-display area 10 includes at least a third sub-area 103 and a fourth sub-area 104, wherein the third sub-area 103 is located on the side of the fourth sub-area 104 facing the display area 20;
[0128] The first dielectric layer 60 is located at least in the third subregion 103; or,
[0129] The first medium layer 60 is located at least in the third subregion 103 and the fourth subregion 104.
[0130] This application provides an optional implementation method in which, when the display panel 100 includes a first electrode 40, a first medium 60, and a first electrode connection structure 30, all of which are disposed in different layers, the electrical connection between the first electrode 40 and the first medium 60 can be configured to be implemented in the non-display area 10, and the electrical connection between the first medium 60 and the first electrode connection structure 30 can also be implemented in the non-display area 10. In this case, the direction from the display area 20 to the non-display area 10 can be selected. The non-display area 10 includes a third sub-area 103 and a fourth sub-area 104, wherein the third sub-area 103 is located on the side of the fourth sub-area 104 facing the display area 20. The first medium 60 can be configured to be located only in the third sub-area 103, or in the third sub-area 103 and at least part of the display area 20, or the first medium 60 can be configured to be located only in the third sub-area 103 and the fourth sub-area 104, or in the third sub-area 103 and the fourth sub-area 104 and at least part of the display area 20.
[0131] Since the first electrode 40 can be configured to be disposed entirely on the display area 20 and extend at least partially into the non-display area 10, when the electrical connection between the first electrode 40 and the first dielectric 60 is realized in the non-display area 10, only the third sub-area 103 needs to be occupied to realize the electrical connection between the first electrode 40 and the first dielectric 60. At this time, the areas of the first electrode 40 and the first dielectric 60 required to be disposed in the non-display area 10 of the display panel 100 are relatively small, which can save the materials required to manufacture the first electrode 40 and the first dielectric 60 in the display panel 100 and reduce the manufacturing cost of the display panel 100; in addition, in the non-display area 100, the first electrode 40 and the first dielectric 60 are relatively small. If the area of zone 10 allows, the first electrode 40 and the first medium 60 can occupy more space in the non-display zone 10 to achieve their electrical connection. For example, the first medium 60 and the first electrode 40 can be located at least in the third sub-zone 103 and the fourth sub-zone 104, thereby increasing the overlap area between the first medium 60 and the first electrode 40, making the electrical connection between the first medium 60 and the first electrode 40 easier to achieve, improving the stability of the electrical connection between the first medium 60 and the first electrode 40, and helping to reduce the difficulty of implementing the electrical connection between the first medium 60 and the first electrode 40.
[0132] Furthermore, when the first medium 60 is located in the third sub-region 103 and the fourth sub-region 104 of the non-display area 10, the electrical connection between the first medium 60 and the first electrode connection structure 30 can be implemented in the fourth sub-region 104, and the electrical connection between the first medium 60 and the first electrode 40 can be implemented in the third sub-region 103. This increases the design freedom for realizing the electrical connection between the first electrode 40 and the first electrode connection structure 30, and at the same time ensures the normal operation of the display panel 100 while reducing the overall area of the non-display area 10 of the display panel 100.
[0133] It should also be noted that when the first dielectric 60 is at least located in the third sub-region 103 and the fourth sub-region 104, even if the first dielectric 60 is burned during the manufacturing process of the display panel 100, the burning will not cause the first dielectric 60 to be completely carbonized. Therefore, it will not affect the material properties of the first dielectric 60, and thus will not affect the effect of the first dielectric 60 as a transition structure on the transmission of electrical signals between the first electrode 40 and the first electrode connection structure 30. Furthermore, the width of the first dielectric 60 can be set to not exceed the outer boundary of the encapsulation area of the display panel 100, and the first dielectric 60 can be edged by the organic film of the upper layer subsequently manufactured. This can avoid the burning problem of the first dielectric 60 during the cutting of subsequent panel processes, ensure the integrity of the first dielectric 60, avoid affecting the electrical connection effect between the first dielectric 60 and the first electrode connection structure 30, and / or avoid affecting the electrical connection effect between the first dielectric 60 and the first electrode 40, thereby ensuring the stability of the transmission of electrical signals between the first electrode 40 and the first electrode connection structure 30.
[0134] In addition, a low-impedance material can be used to fabricate the first dielectric 60, thereby reducing the load on the first dielectric 60 and its influence on the electrical signals transmitted between the first electrode 40 and the first electrode connection structure 30, thus ensuring a good display effect of the display panel 100.
[0135] In addition, it should be noted that please combine with Figure 21 The light-emitting element 94 included in the display panel 100 may have a structure including an anode 942, a light-emitting layer 941, and a cathode (40) stacked sequentially along a direction perpendicular to the plane of the display panel 100. In this case, the first dielectric 60 located in the non-display area 10 can be formed by extending the anode 942 into the non-display area 10, that is, the first dielectric 60 and the anode 942 can be made of the same layer and the same material. The first electrode 40 located in the non-display area 10 can be formed by extending the cathode into the non-display area 10, that is, the first electrode 40 and the cathode can be made of the same layer and the same material. This arrangement can simplify the manufacturing process of the display panel 100, reduce the manufacturing time of the display panel 100, and improve the manufacturing efficiency of the display panel 100. Of course, this is only one possible implementation of the first dielectric 60 and the first electrode 40 provided in this application. Users can also adjust the film layer position and manufacturing process of the first dielectric 60 and the first electrode 40 in the display panel 100 according to actual needs.

Figures 2-29 Reference Figure 30Based on the same inventive concept, this application also provides a display device 200, which includes a display panel 100, and the display panel 100 is any of the display panels 100 provided in this application.
[0137] It should be noted that the embodiments of the display device 200 provided in this application can refer to the embodiments of the display panel 100 described above, and will not be repeated here. The display device 200 provided in this application can be any product and component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, or navigator.
[0138] As can be seen from the above embodiments, the display panel and display device provided by the present invention achieve at least the following beneficial effects:
[0139] This application provides a display panel and a display device. Since the third and fourth non-display areas of the display panel have some areas where structural components can be added, this application sets the first electrode connection structure in the third and / or fourth non-display areas that are arranged opposite each other along the second direction. The first electrode connection structure is located outside the first area that penetrates the display panel along the first direction, so that the setting position of the first electrode connection structure avoids the first and second non-display areas in the display panel. This realizes the utilization of the usable space in the third and / or fourth non-display areas, thereby saving the space required to set the structural components in the first and second non-display areas. This is beneficial to further reduce the space required in the first and second non-display areas of the display panel and further realize the design scheme of narrow bezel of display products.
