[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0043] As mentioned in the background section, existing display devices often suffer from poor display quality in the area surrounding the camera. The inventors discovered through research that the reason for this problem is that existing display devices that place the camera in the display area usually have a transparent display area with high light transmittance. The camera is placed in the transparent display area. To improve the light transmittance of the transparent display area, a transition area is usually set around it. The driving circuit of the transparent display area is located in the transition area. Since the transition area has a different structure from both the main display area and the transparent display area, there are differences between the transition area and the main display area and the transparent display area during display, resulting in a significant difference in the display quality of the area surrounding the camera and affecting the overall display effect.

[0044] Based on this, embodiments of the present invention provide a display panel. Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of the area, for reference. Figure 1 and Figure 2 The display panel includes:

[0045] Display area 10 and non-display area 20 surrounding display area 10. Display area 10 includes a first display area 11 and a second display area 12. The light transmittance of the first display area 11 is greater than that of the second display area 12. The second display area 12 surrounds the first display area 11.

[0046] The first display area 11 includes a plurality of first light-emitting units 40;

[0047] The boundary between the second display area 12 and the non-display area 20 includes a stepped boundary 30. A first driving circuit 50 is provided in the non-display area 20 near the stepped boundary 30. The first driving circuit 50 is used to drive the first light-emitting unit 40 to emit light.

[0048] In this embodiment, display area 10 is used to display images, second display area 12 is the main display area of ​​the display panel, and first display area 11 is the secondary display area of ​​the display panel. First display area 11 has high light transmittance and is used to house optical sensors such as cameras. The stepped boundary 30 is represented by the arc-shaped chamfer of display area 10 in the macroscopic shape of the display panel. The second display area 12 may surround the first display area 11 in a complete circle, or it may surround a portion of the first display area 11; this embodiment does not impose specific limitations.

[0049] A first driving circuit 50 is disposed within the non-display area 20 near the stepped boundary 30, for example, see reference. Figure 2At the stepped boundary 30, the non-display area 20 has a stepped area 21 corresponding to the stepped boundary 20. The stepped area 21 may include multiple steps, and the first driving circuit 50 may be disposed on one, two, or more steps of the stepped area 21. The second display area 12 may include multiple second light-emitting units (not shown in the figure) and a second driving circuit 60, which is used to drive the second light-emitting units to emit light.

[0050] The arrangement of the multiple driving circuits 50 located near the stepped boundary 30 within the non-display area 20 can be the same as or similar to the arrangement of the second driving circuits 60 in the second display area 12; this embodiment does not impose specific limitations. The output terminal of each first driving circuit 50 is electrically connected to the input terminal of the first light-emitting unit 40 it drives. Each first driving circuit 50 can drive one first light-emitting unit 40, or it can drive two or more first light-emitting units 40. The display panel may include multiple stepped boundaries 30; correspondingly, the first driving circuits 50 can be located within the non-display area 20 at the stepped boundary 30, which is relatively close to the first display area 11.

[0051] In this embodiment, by placing the first driving circuit 50, which drives the first light-emitting unit 40 in the first display area 11 to emit light, within the non-display area 20 near the stepped boundary 30, there is no need to add a transition area around the first display area 11. This avoids the transition area affecting the display effect around the first display area 11 and improves the display effect of the display panel. In addition, placing the first driving circuit 50 in the stepped area 21 effectively utilizes the free space at the stepped position.

[0052] Optionally, multiple first drive circuits 50 are arranged adjacent to the stepped boundary 30.

[0053] With this configuration, the first driving circuit 50 is closer to the second display area 12, making more efficient use of the free space at the step of the step area 21. Furthermore, the first driving circuit 50 can be fabricated in the same process as the second driving circuit 60 of the second display area 12, without requiring significant changes to the mask used in the fabrication of the second driving circuit 60, thus minimizing the impact on the process.

[0054] Figure 3 This is a schematic diagram of another display panel provided in an embodiment of the present invention, see reference. Figure 3Optionally, the stepped boundary includes a first stepped boundary 31 and a second stepped boundary 32; along the first direction X, the first stepped boundary 31 and the second stepped boundary 32 are located on both sides of the first display area 11; the first light-emitting unit 40 in the first display area 11 near the first stepped boundary 31 is connected to the first driving circuit 50 in the non-display area near the first stepped boundary 31, and the first light-emitting unit 40 in the first display area 11 near the second stepped boundary 32 is connected to the first driving circuit 50 in the non-display area near the second stepped boundary 32.

[0055] Specifically, the first direction X can be either a row direction or a column direction. Both the first stepped boundary 31 and the second stepped boundary 32 are relatively close to the first display area 11 compared to other stepped boundaries of the display panel. By placing the first driving circuit 50 corresponding to the first light-emitting unit 40 near the first stepped boundary 31 at the first stepped boundary 31, and the first driving circuit 50 corresponding to the first light-emitting unit 40 near the second stepped boundary 32 at the second stepped boundary 32, the connection lines between the first driving circuit 50 and the first light-emitting unit 40 can be distributed on both sides of the first display area 11, which is more conducive to wiring.

[0056] For example, the non-display area includes a first stepped area 211 and a second stepped area 212. The first stepped area 211 is adjacent to the first stepped boundary 31, and the second stepped area 212 is adjacent to the second stepped boundary 32. The first display area 11 includes a first area 121 and a second area 122. The second area 122 and the first area 121 are arranged along a first direction X. The first area 121 is located on the side of the second area 122 adjacent to the first stepped boundary 31. The first driving circuit 50 corresponding to the first light-emitting unit 40 of the first area 121 is disposed in the first stepped area 211, and the first driving circuit 50 corresponding to the first light-emitting unit 40 of the second area 122 is disposed in the second stepped area 212. The first area 121 and the second area 122 can be the same size, and the number of first driving circuits 50 disposed in the first stepped area 211 and the second stepped area 212 can be the same.

[0057] Optional, Figure 4 This is a schematic diagram of another display panel provided in an embodiment of the present invention, see reference. Figures 2-4 The display panel also includes:

[0058] The first light-emitting unit 40 is electrically connected to the corresponding first driving circuit 50 via the connecting line 70.

[0059] refer to Figure 1 and Figure 2 All connecting lines 70 extend from the first driving circuit 50 through the non-display area 20 to the first display area 11 and are electrically connected to the corresponding first light-emitting unit 40; or,

[0060] refer to Figure 3 All connecting lines 70 extend from the first driving circuit 50 through the second display area 12 to the first display area 11 and are electrically connected to the corresponding first light-emitting unit 40; or;

[0061] refer to Figure 1 and Figure 4 One part of the connecting line 70 extends from the first driving circuit 50 through the non-display area 20 to the first display area 11 and is electrically connected to the corresponding first light-emitting unit 40. The other part of the connecting line 70 extends from the first driving circuit 50 through the second display area 12 to the first display area 11 and is electrically connected to the corresponding first light-emitting unit 40.

[0062] Specifically, since the first display area 11 is generally located near the top edge of the display panel, and the bottom edge of the display panel is generally used to house the driver chip, the top edge of the display panel is positioned opposite to the bottom edge. The non-display area 20 corresponding to the top edge has fewer circuits and wires, providing more wiring space. Connecting lines 70 can be set to extend from the non-display area 20 at the top edge of the display panel to the first display area 11. This will not affect other structures, and the wiring method can be more flexible.

[0063] Furthermore, since the second display area 12 is located between the first display area 11 and the stepped boundary, the connecting line 70 can also extend from the second display area 12 to the first display area 11. In this case, the connecting line 70 is shorter, which helps to reduce signal loss and improve the display effect.

[0064] In addition, when some connecting lines 70 extend from the non-display area 20 at the top bezel of the display panel to the first display area 11, and some connecting lines 70 extend from the second display area 12 to the first display area 11, the wiring space is larger, and the spacing between the connecting lines 70 can be larger, so as to avoid mutual interference between the connecting lines 70.

[0065] It should be noted that, for clearer representation of the connecting line 70, Figure 3 and Figure 4 The second drive circuit is not shown in the diagram. Furthermore, Figures 2-4 The diagram only shows a portion of the connecting lines 70 as an example and is not intended to limit the scope of the invention.

[0066] Figure 5 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Optional, see reference. Figure 5 When one part of the connecting line 70 extends from the first driving circuit 50 through the non-display area to the first display area 11 and is electrically connected to the corresponding first light-emitting unit 40, and another part of the connecting line 70 extends from the first driving circuit 50 through the second display area 12 to the first display area 11 and is electrically connected to the corresponding first light-emitting unit 40;

[0067] The second display area 12 includes a plurality of light-emitting sub-pixels 90, and each light-emitting sub-pixel 90 includes a second light-emitting unit and a second driving circuit.

[0068] The non-display area includes a virtual sub-pixel 80, which has the same structure as the light-emitting sub-pixel 90 of the second display area 12, but the virtual sub-pixel does not emit light.

[0069] The connecting line 70, which extends from the non-display area to the first display area 11, passes through the virtual sub-pixel 80 and extends to the first display area 11.

[0070] Specifically, the virtual sub-pixel 80 may also include a light-emitting unit and a driving circuit, and the virtual sub-pixel can be manufactured simultaneously with the light-emitting sub-pixel 90. By setting the virtual sub-pixel 80, the connecting line 70 extending from the non-display area to the first display area 11 extends to the first display area 11 through the virtual sub-pixel 80, so that all connecting lines 70 are in the same or similar environment, reducing the signal differences transmitted by different connecting lines 70 and ensuring that the first display area 11 has a better display effect.

[0071] It should be noted that the second driving circuit and the second light-emitting unit included in the light-emitting sub-pixel 90 are not shown in the figure, and this is not intended to limit the present invention.

[0072] Optionally, the resistance of each connection wire is equal to 70.

[0073] This configuration ensures that the signal loss of different connecting lines 70 is the same or similar, further reducing the signal differences transmitted by different connecting lines 70 and ensuring that the first display area 11 has a better display effect. The resistance of the connecting lines 70 can be adjusted by changing their shape or thickness to make the resistance of different connecting lines 70 equal. For example, some connecting lines 70 can be set to a zigzag shape, a wavy shape, or a rectangular pulse shape, etc.

[0074] Optionally, the portion of the connecting line 70 located in the non-display area and the second display area 12 may be made of metal or transparent conductive material; the portion of the connecting line 70 located in the first display area 11 may be made of transparent conductive material.

[0075] Specifically, metal materials have lower resistance. Using metal materials for the part of the connecting line 70 located in the non-display area and the second display area 12 can reduce the resistance of the connecting line 70 and reduce signal loss.

[0076] The portion of the connecting line 70 located in the first display area 11 is made of a transparent conductive material, which ensures that the first display area 11 has high light transmittance. When the portion of the connecting line 70 located in the non-display area and the second display area 12 is made of a transparent conductive material, it can be fabricated in the same layer as the portion of the connecting line 70 in the first display area 11, without occupying space in other metal circuit layers of the second display area 12 and the non-display area 20, thus reducing the impact of the connecting line 70 on other structures of the second display area 12 and the non-display area 20.

[0077] Optionally, the first display area 11 includes at least two transparent conductive layers, and the connecting lines 70 located in the first display area 11 are distributed across at least two transparent conductive layers. This configuration provides more space for the connecting lines 70 to be distributed, allows for more flexible wiring, avoids mutual interference between the connecting lines 70, and ensures that the first display area 11 has a better display effect.

[0078] Figure 6 This is a cross-sectional view of a display panel provided in an embodiment of the present invention, with reference to... Figure 6 After fabricating the driving circuit layer 102 on the substrate 101, a first insulating layer 103 can be fabricated. Then, a first transparent conductive layer 104 is fabricated on the surface of the first insulating layer 103 in the first display area 11. After fabricating the first transparent conductive layer 104, a second insulating layer 105 can be fabricated. Then, a second transparent conductive layer 106, a third insulating layer 107, and a third transparent conductive layer 108 are fabricated sequentially. The connecting lines of the first display area 11 can be distributed in the first transparent conductive layer 104, the second transparent conductive layer 106, and the third transparent conductive layer 108. The first insulating layer 103 and the second insulating layer 105 can be inorganic insulating layers, and the third insulating layer 107 can be an organic insulating layer. The third insulating layer 107 can serve the functions of planarization and insulation. In addition, after the third transparent conductive layer 108 is fabricated, the anode of the light-emitting unit can be directly fabricated. The anode is electrically connected to the corresponding connecting line in the third transparent conductive layer 108. It should be noted that... Figure 6 The example shown illustrates a case where the first display area 11 includes three transparent conductive layers, which is not intended to limit the invention. In other embodiments, when two transparent conductive layers are sufficient to lay the connecting lines 70, only two transparent conductive layers may be provided.

[0079] Figure 7 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Optional, see reference. Figure 7 The display panel also includes:

[0080] Multiple display control lines 201 extending along the first direction X and multiple data lines 202 extending along the second direction Y;

[0081] The second display area 12 includes a plurality of second driving circuits 60;

[0082] The data signal input terminal of each first driving circuit 50 is electrically connected to the data line 202 connecting the first driving circuit 50 to the adjacent second driving circuit 60 along the second direction Y.

[0083] Each first driving circuit 50 has its control signal input terminal electrically connected to a display control line 201 connected to a second driving circuit 60 adjacent to it along the first direction X; wherein, the display control line 201 includes at least one of a scan line, an emissive control line, and a reset signal line.

[0084] This configuration ensures that the display control line 201 and data line connected to the first drive circuit 50 are both close to it, reducing connection difficulty and signal loss.

[0085] Figure 8 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Optional, see reference. Figure 8 The first driving circuit 50 is electrically connected to the first light-emitting unit in a one-to-one correspondence, and the first driving circuit 50 is used to drive the corresponding first light-emitting unit to emit light.

[0086] Alternatively, the first display area 11 may include multiple light-emitting unit groups, each light-emitting unit group including at least two first light-emitting units, and each first driving circuit 50 may be electrically connected to the first light-emitting units of a light-emitting unit group, and the first driving circuit 50 may be used to drive its corresponding light-emitting unit group to emit light.

[0087] refer to Figure 8 The light-emitting unit includes a first color light-emitting unit 41, a second color light-emitting unit 42, and a third color light-emitting unit 43. Figure 8 The diagram shows a first display area 11 comprising multiple sub-areas 100. Each sub-area 100 includes four first-color light-emitting units 41, four second-color light-emitting units 42, and four third-color light-emitting units 43. The four first-color light-emitting units 41 in the same sub-area 100 can form a light-emitting unit group electrically connected to the same first driving circuit 50; the four second-color light-emitting units 42 in the same sub-area 100 can form a light-emitting unit group electrically connected to the same first driving circuit 50; and the four third-color light-emitting units 43 in the same sub-area 100 can form a light-emitting unit group electrically connected to the same first driving circuit 50. The anodes of the multiple first light-emitting units in a light-emitting unit group can be electrically connected together, for example, through a transparent conductive layer, such as... Figure 6The third transparent conductive layer 108 is in place, so that the first driving circuit 50 can drive the light-emitting unit group by connecting to the anode of any one of the first light-emitting units in the light-emitting unit group through a connecting line. Setting one first driving circuit 50 to drive one light-emitting unit group can reduce the number of first driving circuits 50, reduce the number of connecting lines 70, and reduce the wiring and manufacturing difficulty.

[0088] In addition, the first driving circuit 50 can also be electrically connected to the first light-emitting unit in a one-to-one correspondence. In this way, each first light-emitting unit is driven by a separate first driving circuit 50. When the number of first light-emitting units in the first display area 11 is equal, the actual number of pixels in the first display area 11 can be increased, that is, the pixel density (Pixels per inch, PPI) of the first display area 11 can be increased, thereby improving the display effect of the second display area.

[0089] It should be noted that, Figure 8 The diagram only shows a partial connection between the first light-emitting unit and the first driving circuit, and is not intended to limit the invention. Other connection methods may be used in other embodiments.

[0090] This invention also provides a display device that includes the display panel described in any embodiment of the invention.

[0091] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0092] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors.
