[0052] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0053] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0054] As mentioned in the background technology, the secondary screen area of ​​the existing display panel needs to be equipped with a light-sensitive device, so the transmittance of the secondary screen area needs to be improved. How to improve the transmittance of the secondary screen area while improving the display effect of the secondary screen area has become a technical problem that needs to be solved urgently in the industry. After long-term research, the inventor found that the reason for the poor display effect of the secondary screen area is that in order to improve the display effect of the secondary screen area and realize a full screen, the number of pixels in the secondary screen area is increased, and the number of pixel driving circuits in the secondary screen area is increasing. Since the length of the electrode traces in the secondary screen area is too long, the resistance of the electrode traces is large, which affects the uniformity of the signal transmitted on the electrode traces, and thus affects the display effect of the display panel.

[0055] Figure 1It is a structural schematic diagram of a display panel provided by an embodiment of the present invention. Figure 2 This is a schematic diagram of the distribution of sub-pixels of a display panel provided by an embodiment of the present invention. Figure 3 This embodiment of the present invention provides a Figure 1 An enlarged schematic diagram of the D1 region in the middle display panel. Figure 4 Another embodiment of the present invention provides Figure 1 The enlarged schematic diagram of the D1 region in the middle display panel. Figures 1 to 4 The display panel provided by the embodiment of the present invention includes a first display area 10 and a second display area 20, and the transmittance of the second display area 20 is greater than the transmittance of the first display area 10; the display panel also includes a first sub-pixel 1, which is arranged in the first display area 10 and electrically connected to the first pixel driving circuit 11; a second sub-pixel 2, which is arranged in the second display area 20 and electrically connected to the second pixel driving circuit 21 through an electrode trace 3; the first pixel driving circuit 11 and the second pixel driving circuit 21 are arranged in the first display area 10; the electrode trace 3 includes a first trace 31 extending at least partially along the first direction X and a second trace 32 extending at least partially along the second direction Y, wherein the second direction Y intersects with the first direction X; the second pixel driving circuit 21 connected to the second trace 32 and the second pixel driving circuit 21 connected to the first trace 31 are located in different rows.

[0056] Specifically, the first display area 10 can be a main screen area or a transition area, and the second display area 20 can be a transparent display area or a transition display area. The second sub-pixel 2 of the second display area 20 is electrically connected to the second pixel driving circuit 21 provided in the first display area 10 via the electrode trace 3. The first sub-pixel 1 of the first display area 10 is electrically connected to the first pixel driving circuit 11 provided in the first display area 10. The second sub-pixel 2 is driven by the second pixel driving circuit 21 located in the first display area 10, so that the second display area 20 does not have the second pixel driving circuit 21, so that the second display area 20 has a higher transmittance, which facilitates the installation of optical sensing devices such as optical sensors and camera devices that have higher transmittance requirements.

[0057] At least a portion of the first wiring 31 extends along the first direction X, so that the second sub-pixel 2 is connected to the second pixel driving circuit 21 located in the first direction X. At least a portion of the second wiring 32 extends along the second direction Y, so that the second sub-pixel 2 is connected to the second pixel driving circuit 21 located in the second direction Y. By arranging the second pixel driving circuit 21 connected to the second wiring 32 and the second pixel driving circuit 21 connected to the first wiring 31 to be located in different rows. This arrangement, on the one hand, allows the second sub-pixels 2 located in the second display area 20 to lead out as many electrode wirings 3 as possible, thereby improving the pixel density of the second display area 20; on the other hand, it allows the lengths of the first wiring 31 and the second wiring 32 to be as consistent as possible, thereby preventing the length of the second wiring 32 from being too long, thereby reducing the resistance on the second wiring 32, improving the uniformity of the signal transmitted on the second wiring 32, and thus improving the display effect of the display panel.

[0058] The technical solution provided in this embodiment comprises an electrode trace 3 comprising a first trace 31 and a second trace 32. At least a portion of the first trace 31 extends along a first direction X, wherein the first direction X extends along the row direction of the first sub-pixels 1; and at least a portion of the second trace 32 extends along a second direction Y, wherein the second direction Y intersects the first direction X. This allows for a greater number of second sub-pixels 2 in the second display area 20, thereby expanding the wiring area of ​​the electrode trace 3. This allows for the number of second pixel driver circuits 21 connected to the second sub-pixels 2 in the second display area 20 to be consistent with the number of second sub-pixels 2, thereby increasing the pixel density of the second display area 20 and improving the display quality of the display panel. Furthermore, by arranging the second pixel driver circuits 21 connected to the second trace 32 and the second pixel driver circuits 21 connected to the first trace 31 in different rows, the electrode trace 3 allows for connection to the nearest second pixel driver circuit 21 based on the position of the second sub-pixel 2. This shortens the length of the electrode trace 3, reduces the resistance of the electrode trace 3, and improves the uniformity of the signal transmitted on the electrode trace 3, thereby improving the display quality of the display panel.

[0059] It should be noted that this embodiment only exemplifies the arrangement of the first sub-pixel 1 and the second sub-pixel 2 and is not intended to limit the present invention. In other embodiments, the arrangement of the first sub-pixel 1 and the second sub-pixel 2 may be an RGB arrangement, an RGBG arrangement, a pentile arrangement (diamond arrangement), an RGBW arrangement, an RGB Delta arrangement, an RGB S-Strip arrangement, or other arrangements.

[0060] The second display area 20 may be in a square, circular, or track-shaped shape, which is not limited here. In an optional application scenario, the display panel may be a full screen, and at least a portion of the second display area 20 is surrounded by the first display area 10 .

[0061] Optional, Figure 5 Another embodiment of the present invention provides Figure 1 FIG. 1 is an enlarged schematic diagram of the D1 region of the display panel. Based on the above embodiment, see Figure 5 , the electrode wiring 3 includes at least two wiring layers.

[0062] Specifically, this arrangement further increases the number of electrode traces 3 that can be drawn out, further saving the space occupied by the electrode traces 3 connected to the second sub-pixel 2. Figure 4 The dotted lines exemplarily represent the first and second traces 31 and 32 located in the same trace layer, and the solid lines represent the first and second traces 31 and 32 located in another trace layer. The number of trace layers included in the electrode trace 3 can be set as needed and is not limited here.

[0063] Optionally, based on the above embodiment, continue to refer to Figure 5 The second display area 20 may include at least a first light-transmitting area 201 and a second light-transmitting area 202, and the first light-transmitting area 201 and the second light-transmitting area 202 are arranged in sequence along the first direction X; the first light-transmitting area 201 is located between the first display area 10 and the second light-transmitting area 202; the second sub-pixel 2 located in the first light-transmitting area 201 is electrically connected to the second pixel driving circuit 21 through the first wiring 31; the second sub-pixel 2 located in the second light-transmitting area 202 is electrically connected to the second pixel driving circuit 21 through the second wiring 32; preferably, the electrode wiring 3 includes a first wiring layer S1 and a second wiring layer S2.

[0064] Specifically, the second display area 20 includes at least one first light-transmitting area 201 and a second light-transmitting area 202. The first light-transmitting area 201 is disposed between the first display area 10 and the second light-transmitting area 202. When the second display area 20 includes two or more first light-transmitting areas 201, the two or more first light-transmitting areas 201 can be disposed on different sides of the second light-transmitting area 202. It is sufficient to ensure that the first light-transmitting area 201 is located between the first display area 10 and the second light-transmitting area 202. Figure 5 The case where the second display area 20 includes a first light-transmitting area 201 is exemplarily shown, and no limitation is given here.

[0065] Because the first light-transmitting area 201 is disposed between the first display area 10 and the second light-transmitting area 202, the second sub-pixel 2 located in the first light-transmitting area 201 is electrically connected to the corresponding second pixel driving circuit 21 located in the first display area 10 via the first routing line 31, and the first routing line 31 passes through the first light-transmitting area 201. This arrangement facilitates the electrical connection of the second sub-pixel 2 located in the first light-transmitting area 201 with the corresponding second pixel driving circuit 21 located in the first display area 10 via the first routing line 31, thereby shortening the routing of the first routing line 31 from the first light-transmitting area 201 to the first display area 10, thereby saving routing space on the display panel.

[0066] Because the first light-transmitting region 201 is disposed between the second light-transmitting region 202 and the first display region 10, the second sub-pixel 2 located in the second light-transmitting region 202 is electrically connected to the corresponding first pixel driving circuit 11 located in the first display region 10 via the second trace 32. This shortens the route from the second trace 32 to the first display region 10, further saving trace space on the display panel. This shortened length of the second trace 32 reduces the resistance of the second trace 32, improves the uniformity of the signal transmitted on the electrode trace 3, and further improves the display quality of the display panel.

[0067] Preferably, Figure 6 FIG is a structural diagram of another display panel provided by an embodiment of the present invention. Figure 6 The electrode traces 3 include a first trace layer S1 and a second trace layer S2. This arrangement can further expand the wiring area of ​​the electrode traces 3, so that the number of second pixel driving circuits 21 connected to the second sub-pixels 2 in the second display area 20 can be consistent with the number of second sub-pixels 2, further increasing the pixel density of the second display area 20 and improving the display effect of the display panel.

[0068] It should be noted that Figure 6 The dotted line represents the first wiring layer S1 and the solid line represents the second wiring layer S2. Optionally, the first wiring layer S1 and the second wiring layer S2 may be transparent conductive wiring, such as ITO (tin-doped indium oxide) wiring.

[0069] Optionally, based on the above embodiment, continue to refer to Figure 6 The first light-transmitting area 201 may include: a first sub-area A and a second sub-area B sequentially arranged along the first direction X; the first sub-area A is arranged between the first display area 10 and the second sub-area B; the first trace 31 connected to the second sub-pixel 2 located in the first sub-area A is located in the first trace layer S1 and / or the second trace layer S2; the first trace 31 connected to the second sub-pixel 2 located in the second sub-area B is located in the second trace layer S2. It should be noted that Figure 6The case where the first wiring 31 connected to the second sub-pixel 2 located in the first sub-region A is located in the first wiring layer S1 and the second wiring layer S2 is exemplarily shown, and no limitation is given here.

[0070] Specifically, this arrangement maximizes the number of first routing lines 31 passing through the first sub-region A and the number of first routing lines 31 connected to the second sub-pixels 2 located in the second sub-region B. This increases the number of first routing lines 31 connected to the second sub-pixels 2. Within the same wiring space, the second display area 20 can be provided with more second routing lines 32 connected to the first routing lines 31. This arrangement increases the sub-pixel density of the second sub-pixels 2 located in the second display area 20, significantly improving the display quality of the second display area 20 and, consequently, the display quality of the display panel.

[0071] By arranging the first routing line 31 connected to the second sub-pixel 2 in the second sub-region B in the second routing layer S2, space in the first routing layer S1 can be reserved for arranging the second routing line 32 connected to the second sub-pixel 2 in the second light-transmitting area 202.

[0072] Optionally, based on the above embodiment, continue to refer to Figure 6 The second light-transmitting area 202 may include a third sub-area C and a fourth sub-area D extending along the second direction Y. The third sub-area C is disposed between the fourth sub-area D and the first display area 10. The second routing line 32 connected to the second sub-pixel 2 located in the third sub-area C is located on the first routing layer S1 and the second routing layer S2. Preferably, the orthographic projections of the second routing line 32 located in the first routing layer S1 and the second routing line 32 located in the second routing layer S2 on the first routing layer S1 do not overlap. The second routing line 32 connected to the second sub-pixel 2 located in the fourth sub-area D is located on the first routing layer S1 and the second routing layer S2. Preferably, the orthographic projections of the second routing line 32 located in the first routing layer S1 and the first routing line 31 connected to the second sub-pixel 2 located in the second sub-area B on the first routing layer S1 intersect perpendicularly.

[0073] Specifically, setting the second routing line 32 connected to the second sub-pixel 2 located in the third sub-region C in the first routing layer S1 and the second routing layer S2 can better increase the number of second routing lines 32 connected to the second sub-pixel 2 located in the third sub-region C and lead out as many second routing lines 32 as possible.

[0074] The orthographic projections of the second routing line 32 located in the first routing layer S1 and the second routing line 32 located in the second routing layer S2 on the first routing layer S1 do not overlap, so as to better avoid signal interference between the second routing line 32 located in the first routing layer S1 and the second routing line 32 located in the second routing layer S2, thereby further improving the display effect of the second sub-pixel 2 located in the third sub-region C.

[0075] The second routing lines 32 connected to the second sub-pixels 2 located in the fourth sub-region D are located in the first routing layer S1 and the second routing layer S2, which can better increase the number of second routing lines 32 connected to the second sub-pixels 2 located in the fourth sub-region D and lead out as many second routing lines 32 as possible.

[0076] Preferably, the second routing line 32 of the first routing layer S1 located in the fourth sub-area D and the first routing line 31 connected to the second sub-pixel 2 located in the second sub-area B intersect vertically at the positive projection of the first routing layer S1. This arrangement reduces the signal interference between the second routing line 32 of the first routing layer S1 located in the fourth sub-area D and the first routing line 31 connected to the second sub-pixel 2 located in the second sub-area B, thereby further improving the display effect of the display panel.

[0077] Optionally, based on the above embodiment, continue to refer to Figure 6 At least a portion of the second routing line 32 located in the first routing layer S1 passes through the second sub-region B; wherein the second routing line 32 is connected to the second sub-pixel 2 located in the fourth sub-region D.

[0078] Specifically, the second routing line 32 of the first routing layer S1 located in the fourth sub-region D passes through the second sub-region B and is connected to the second pixel driving circuit 21 located in the first display area 10. This, on the one hand, facilitates the extraction of the second routing line 32 located in the fourth sub-region D, providing sufficient space for the second routing line 32 located in the fourth sub-region D. On the other hand, because the second routing line 32 connected to the second sub-pixel 2 located in the second sub-region B is located in the second routing layer S2, and the second routing line 32 located in the first routing layer S1 passes through the second sub-region B, wiring space is increased, signal interference between the second routing line 32 of the first routing layer S1 located in the fourth sub-region D and the first routing line 31 connected to the second sub-pixel 2 located in the second sub-region B is reduced, further improving the display effect of the display panel.

Furthermore, the pixel arrangement of the first display area 10 and the second display area 20 can be the same, so that the sub-pixels of the second display area 20 can be manufactured in the same process as the sub-pixels of the first display area 10, reducing process costs.
