[0032] This application is proposed to solve the aforementioned technical problems. To better understand this application, the following is combined with... Figures 1 to 3 The display panel and display device according to the embodiments of this application will be described in detail.

[0033] This invention provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a top view schematic diagram of a display panel provided in the first aspect embodiment of this application. Figure 2 This is a partial cross-sectional view of a display panel provided in the first aspect of this application.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of this application provides a display panel having a first region AA1 and a second region AA2 spaced apart, and a third region connected between the first region AA1 and the second region AA2. The display panel includes a substrate 100, a light-emitting layer 200, and a bonding layer. The light-emitting layer 200 is disposed on one side of the substrate 100 and includes a first light-emitting unit 211 located in the first region AA1 and a second light-emitting unit 212 located in the second region AA2. The bonding layer is disposed on the side of the substrate 100 away from the light-emitting layer 200 and includes a plurality of bonding pins 300, wherein a portion of the plurality of bonding pins 300 is used for electrically connecting the first light-emitting unit 211 and a drive controller 400, and another portion of the plurality of bonding pins 300 is used for electrically connecting the second light-emitting unit 212 and the drive controller 400.

[0036] Figure 1 The location of the bonding pin 300 is indicated by a dashed line. The dashed line is not intended to limit the structure of the display panel in this application. Figure 1 Only a portion of the light-emitting units 210 are shown in the diagram.

[0037] In the display panel provided in this embodiment, the display panel has a first region AA1, a second region AA2, and a third region connected between the first region AA1 and the second region AA2. A first light-emitting unit 211 is located in the first region AA1 to realize the display of the first region AA1, and a second light-emitting unit 212 is located in the second region AA2 to realize the display of the second region AA2. Bonding pins 300 of the bonding layer are disposed on the side of the substrate 100 away from the light-emitting layer 200, meaning the bonding layer is disposed on the non-display side of the display panel. The bonding layer includes multiple bonding pins 300 located in the third region. The bonding pins 300 are used for electrical connection with the first light-emitting unit 211 and the second light-emitting unit 212 to transmit control signals to the light-emitting units. Since the bonding pins 300 are located on the non-display side of the display panel, the connection between the bonding pins 300 and the external devices connected to them will not affect the display of the display panel. The shapes of the first region AA1 and the second region AA2 can be set according to actual needs, and the third region does not restrict the shapes of the first region AA1 and the second region AA2, thereby improving the display effect of the display panel.

[0038] Optionally, both the first light-emitting unit 211 and the second light-emitting unit 212 are light-emitting units 210 of the display panel.

[0039] In addition, the first zone AA1 and the second zone AA2 are distributed at intervals, and the third zone is connected between the first zone AA1 and the second zone AA2, so that the third zone is close to both the first zone AA1 and the second zone AA2. The signal lines of the first zone AA1 and the second zone AA2 can be extended and connected to the bonding pin 300 of the third zone.

[0040] Optionally, the substrate 100 can be an array substrate 100, which includes a substrate and a driving circuit disposed on the substrate. Optionally, the array substrate includes a first conductive layer, a second conductive layer, and a third conductive layer stacked together. An insulating material layer is disposed between adjacent conductive layers. For example, the pixel driving circuit disposed on the array substrate includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate, a source, and a drain. The storage capacitor includes a first electrode and a second electrode. As an example, the gate and the first electrode may be located on the first conductive layer, the second electrode may be located on the second conductive layer, and the source and drain may be located on the third conductive layer.

[0041] Optionally, the substrate 100 may also include signal lines, such as power signal lines, voltage reference signal lines, data lines, scan lines, etc. Figure 1 Some signal lines are indicated by dashed lines.

[0042] Optionally, the signal lines within the substrate 100 can be connected to the bonding pins 300, such that the bonding pins 300 are electrically connected to the light-emitting unit 210 via the signal lines. The end of the signal line connected to the bonding pin 300 can extend along the thickness direction toward the bonding pin 300 and connect to it. The bonding pins 300 are pads disposed on the surface of the substrate 100, and these pads are interconnected with the signal lines within the substrate 100.

[0043] Optionally, the light-emitting layer 200 includes a pixel definition layer, which includes an isolation portion and a pixel opening formed by the isolation portion. The first light-emitting unit 211 and the second light-emitting unit 212 may be located within the pixel opening.

[0044] Optional, please continue reading Figure 2 The display panel also includes a drive controller 400 connected to the bonding pin 300, which allows the drive controller 400 to transmit control signals to the light-emitting unit 210 through the bonding pin 300.

[0045] There are several ways to set the relative positions of Zone AA1 and Zone AA2. For example, Zone AA1 and Zone AA2 can be set side by side.

[0046] In some alternative embodiments, the second area AA2 surrounds the first area AA1, which can increase the display area of ​​the second area AA2 and improve the display effect of the display panel. For example, when the display panel is used in a smartwatch, the arrangement of the second area AA2 surrounding the first area AA1 can increase the overall display area of ​​the smartwatch.

[0047] Optionally, the second zone AA2 surrounds the third zone, and the third zone surrounds the first zone AA1. That is, the first zone AA1, the third zone, and the second zone AA2 are nested inside each other from the inside out. The third zone is located between the first zone AA1 and the second zone AA2, so that the third zone can be used to set the driving circuit 150 and bonding pin 300 of the first zone AA1 and / or the second zone AA2, etc., which can ensure the regularity of the shape of the first zone AA1 and the second zone AA2.

[0048] Optionally, the first area AA1 is circular, the second area AA2 is annular, and the third area is annular. For example, both the second area AA2 and the third area are annular. This makes the display panel more adaptable to the usage scenarios of smartwatches. In other embodiments, the first area AA1 can be rectangular, polygonal, or other shapes, and the second area AA2 and the third area can also be other shapes.

[0049] Optionally, the bonding pin 300 includes a first bonding pin 311 for electrical connection with the first light-emitting unit 211 and a second bonding pin 312 for electrical connection with the second light-emitting unit 212. The first bonding pin 311 is capable of electrically connecting to the first light-emitting unit 211 and transmitting control signals to the first light-emitting unit 211, and the second bonding pin 312 is capable of connecting to the second light-emitting unit 212 and transmitting control signals to the second light-emitting unit 212.

[0050] In related technologies, when the bonding pin 300 is disposed on the side of the substrate 100 facing the light-emitting unit 210, in order to achieve the bonding of the controller and the bonding pin 300 on the non-display side, the third region needs to bend across the first region AA1 to the back side of the substrate 100. The third region will block at least part of the space of the second region AA2, causing that part of the second region AA2 to be unable to perform the display function.

[0051] In this embodiment, since the bonding pin 300 is directly disposed on the back side of the substrate 100, it is not necessary to bend the third region across the second region AA2 to the back side of the substrate 100, allowing the second region AA2 to form a continuous ring structure surrounding the first region AA1. Furthermore, the signal lines of the first region AA1 and the second region AA2 can extend directly to the substrate 100 of the third region to connect with the bonding pin 300, reducing the distance between the bonding pin 300 and the first light-emitting unit 211 and the second light-emitting unit 212, thus reducing the signal transmission distance and improving the signal transmission effect.

[0052] In some optional embodiments, the third region includes an adjacent bonding region BA and a wiring region NA. Multiple bonding pins 300 are located within the bonding region BA, and the display panel has a driving circuit 150 within the wiring region NA. In these optional embodiments, the third region is divided into adjacent BA and wiring regions NA. The wiring region NA is used to house the driving circuit 150, and the bonding region BA is used to house the bonding pins 300. This facilitates the partitioning of the driving circuit 150 and bonding pins 300, and the closer distance between the bonding pins 300 and the driving circuit 150 reduces the signal transmission path length and improves control accuracy.

[0053] Please refer to the following: Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of the structure of a display panel provided in another embodiment of the first aspect of this application.

[0054] In some alternative embodiments, such as Figure 2 and Figure 3As shown, the light-emitting layer 200 also includes a third light-emitting unit 213 located in the bonding region BA, and a portion of the bonding pins 300 is used for electrically connecting the third light-emitting unit 213 and the drive controller 400. For example, the bonding pins 300 include a third bonding pin 313, which is used to connect the third light-emitting unit 213 and the drive controller 400.

[0055] In these optional embodiments, since the bonding pin 300 is located on the non-display side of the substrate 100, a third light-emitting unit 213 can be provided on the display side of the substrate 100. This increases the display area AA of the display panel. Furthermore, by providing the third light-emitting unit 213 in the bonding area BA, these third light-emitting units 213, together with the first light-emitting unit 211 or the second light-emitting unit 212, can form an irregularly shaped display area AA that meets user requirements. In addition, the connection between the third bonding pin 313 located in the bonding area BA and the third light-emitting unit 213 can also reduce the distance between the bonding pin 300 and the third light-emitting unit 213.

[0056] Figure 3 Only one third light-emitting unit 213 located in the binding area BA is shown in the figure. There can be multiple third light-emitting units 213.

[0057] After the third light-emitting unit 213 is set in the bonding area BA, optionally, the substrate 100 also includes a third signal line 140 for driving the third light-emitting unit 213. The third bonding pin 313 is connected to the third signal line 140, so that the third signal line 140 can transmit control information through the third bonding pin 313. The third signal line 140 includes, for example, a data signal line.

[0058] Optionally, the third signal line 140 is located in the bonding area BA to reduce the distance between the third signal line 140 and the third bonding pin 313 and the third light-emitting unit 213.

[0059] In some alternative embodiments, the driving circuit 150 further includes a gate driving circuit.

[0060] Optionally, the wiring area NA is connected to the bonding area BA on both sides of the first area AA1 in the circumferential direction. This means that the bonding area BA and the wiring area NA are connected end-to-end around the first area AA1. For example, the bonding area BA is located on one side of the first area AA1 in the second direction Y, and the bonding area BA has a first side and a second side opposite to each other in the first direction X. The wiring area NA extends around the first area AA1 and from the first side to the second side along the path of the bonding area BA. In these optional embodiments, a driving circuit 150 is provided within the wiring area NA, such that the driving circuit 150 can simultaneously drive the first light-emitting unit 211 and the second light-emitting unit 212 located on both sides thereon. Optionally, a scan line is provided on the substrate 100, and the driving circuit 150 is connected to the scan line.

Optionally, the driving circuit 150 includes a first gate driving circuit 151 and a second gate driving circuit 152, which are respectively located on both sides of the first region AA1 in the first direction X. This allows the first light-emitting unit 211 to be driven simultaneously from both sides of the first region AA1. The first gate driving circuit 151 and the second gate driving circuit 152 can also be used to drive second light-emitting units 212 at different positions within the second region AA2.

[0062] In some optional embodiments, the driving circuit 150 further includes a third gate driving circuit 153, which and the bonding region BA are respectively disposed on both sides of the first region AA1 in the second direction Y. The third gate driving circuit 153 can be used to drive the first light-emitting unit 211 in the first region AA1 or the second light-emitting unit 212 in the second region AA2 that is away from the bonding region BA.

[0063] In some optional embodiments, the substrate 100 includes a first signal line 110 for driving the first light-emitting unit 211 to emit light, the first signal line 110 being located in the first region AA1; a first bonding pin 311 is connected to the first signal line 110. The first signal line 110 can be connected to the drive controller 400 via the first bonding pin 311.

[0064] Optionally, the first signal line 110 includes a data signal line, and a plurality of first light-emitting units 211 are arranged in rows and columns along the first direction X and the second direction Y. The first signal line 110 can connect a plurality of first light-emitting units 211 in the same column.

[0065] The first bonding pin 311 can be directly connected to the first signal line 110. For example, the first signal line 110 extends from the first region AA1 to the bonding region BA within the substrate 100. The connection end on the first signal line 110 for connecting the first bonding pin 311 extends toward the side of the substrate 100 away from the display side and is interconnected with the first bonding pin 311.

[0066] In some alternative embodiments, the substrate 100 further includes a first fan-out line 120, which connects at least a portion of the first signal line 110 and the first bonding pin 311. Optionally, at least a portion of the first fan-out line 120 may be located within a wiring area NA between the first area AA1 and the second area AA2.

[0067] In some optional embodiments, the substrate 100 further includes a second signal line 130 for driving the second light-emitting unit 212 to emit light, and a second bonding pin 312 is connected to the second signal line 130. The second signal line 130 can be connected to the drive controller 400 through the second bonding pin 312. Optionally, the second signal line 130 includes a data signal line for connecting one or more second light-emitting units 212.

[0068] In some alternative embodiments, the second region AA2 is arranged around the first region AA1, and a plurality of second light-emitting units 212 are spaced apart in the second region AA2 and arranged around the first region AA1. The second signal line 130 includes a first connecting segment 131 and a second connecting segment 132. The first connecting segment 131 extends along a path around the first region AA1 and connects the plurality of second light-emitting units 212. The second connecting segment 132 connects the first connecting segment 131 and the second bonding pin 312.

[0069] In these optional embodiments, the second region AA2 is arranged around the first region AA1, and a plurality of second light-emitting units 212 are arranged around the first region AA1 within the second region AA2. That is, the plurality of second light-emitting units 212 are spaced apart along the extension path of the second region AA2, and the distribution path of the plurality of second light-emitting units 212 is consistent with the extension path of the second region AA2, which can improve the display effect of the second region AA2. When the plurality of second light-emitting units 212 are spaced apart around the first region AA1, the first connecting segment 131 of the second signal line 130 extends along the path surrounding the first region AA1 to connect the plurality of second light-emitting units 212, and the second connecting segment 132 connects the first connecting segment 131 and the second bonding pin 312.

[0070] Optionally, the second zone AA2 is a closed loop, and at least two sets of second signal lines 130 are respectively disposed on both sides of the first zone AA1 in the first direction X, and the second connecting segment 132 of the two sets of second signal lines 130 disposed on both sides of the first zone AA1 in the first direction X is located between the first connecting segment 131 of the two sets of second signal lines 130.

[0071] In these optional embodiments, at least two sets of second signal lines 130 are respectively disposed on both sides of the first region AA1 in the first direction X, so that multiple second light-emitting units 212 located on the same annular path surrounding the first region AA1 can be connected to two different second signal lines 130. For example, the second light-emitting units 212 disposed on both sides of the first region AA1 in the first direction X can be connected to two different second signal lines 130, which can reduce the signal transmission distance and improve the display effect.

[0072] Optionally, the second connecting segments 132 of the two sets of second signal lines 130 disposed on both sides of the first region AA1 in the first direction X are located between the first connecting segments 131 of the two sets of second signal lines 130. In these optional embodiments, the distance between the second connecting segments 132 of the second signal lines 130 disposed on both sides of the first region AA1 in the first direction X is relatively small, reducing the spacing between the multiple second connecting segments 132, so that the display panel can be centrally wired, and the bonding area BA can be arranged on one side of the first region AA1, so that the multiple second bonding pins 312 are connected to the multiple second connecting segments 132 one by one.

[0073] There are several ways to arrange the multiple bonding pins 300 in the third region. For example, the third region is located on one side of the first region AA1 in the second direction Y, and the multiple bonding pins 300 are arranged in a row along the first direction and in a column along the second direction. This makes the arrangement of the multiple bonding pins 300 more regular and easier to manufacture.

[0074] For example, multiple bonding pins 300 are arranged in a single row. That is, multiple bonding pins 300 are spaced apart along the first direction X. Alternatively, multiple bonding pins 300 are arranged in multiple rows and columns along the first direction X and the second direction Y, where the first direction X is the row direction and the second direction Y is the column direction.

[0075] In these embodiments, when the number of bonding pins 300 is small, or the size of the third region is large enough, the multiple bonding pins 300 can be arranged in a single row along the first direction X to facilitate wiring. When the number of bonding pins 300 is large, or the size of the third region in the first direction X is not large enough, the multiple bonding pins 300 can be arranged in multiple rows and columns along the first direction X and the second direction Y.

[0076] Optionally, multiple bonding pins 300 are arranged in multiple rows and columns along the first direction X and the second direction Y, and adjacent rows of bonding pins 300 are staggered. The staggered arrangement of adjacent rows of bonding pins 300 along the second direction Y means that in two adjacent rows of bonding pins 300, the bonding pins 300 in one row and the bonding pins 300 in the other row are misaligned in the second direction Y. For example, the bonding pins 300 in one row are located between two adjacent bonding pins 300 in the same row. This staggered arrangement of bonding pins 300 can improve the positional interference problem of multiple signal lines.

[0077] Optionally, when the bonding pin 300 includes a first bonding pin 311 and a second bonding pin 312, multiple first bonding pins 311 can be located in the same row, multiple second bonding pins 312 can be located in the same row, and the first bonding pins 311 and the second bonding pins 312 can be located in different rows. The first bonding pin 311 is located on the side of the second bonding pin 312 facing the first area AA1, and the second bonding pin 312 is located on the side of the first bonding pin 311 facing the second area AA2, so that the first signal line 110 extending from the first area AA1 can be connected to the first bonding pin 311, and the second signal line 130 extending from the second area AA2 can be connected to the second bonding pin 312.
