Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display panel and a display device. Background Art

[0002] In existing display devices, since it is necessary to integrate photosensitive components such as a front camera, a fingerprint recognition element, and an infrared sensing element, holes are formed in the display panel to form a photosensitive functional area. In this way, external light can enter the photosensitive component located below the display panel through the photosensitive functional area on the display panel.

[0003] Due to the existence of through holes in the photosensitive functional area, the signal lines around the photosensitive functional area need to be correspondingly connected around the photosensitive functional area, resulting in a relatively large border area around the photosensitive functional area and affecting the screen-to-body ratio of the display panel. Summary of the Invention

[0004] The present invention provides a display panel and a display device to reduce the influence of wire routing on the screen-to-body ratio.

[0005] On the one hand, the present invention provides a display panel, including:

[0006] A first photosensitive functional area and a second photosensitive functional area; the first photosensitive functional area and the second photosensitive functional area are arranged in parallel along a first direction, and the length of the first photosensitive functional area along the first direction is greater than the length of the second photosensitive functional area along the first direction;

[0007] A first display area, a second display area, and a third display area; the first display area is adjacent to the first photosensitive functional area and the second photosensitive functional area in the first direction respectively, the second display area is adjacent to the first photosensitive functional area in a second direction, and the third display area is adjacent to the second photosensitive functional area in the second direction;

[0008] Multiple first-type signal lines; at least a part of the first-type signal lines extends along the second direction, and the first-type signal lines are used to transmit a first signal to the pixel circuit; at least a part of the first-type signal lines in the second display area is separated into two independent wire routing parts by the first photosensitive functional area, and at least a part of the first-type signal lines in the third display area is separated into two independent wire routing parts by the second photosensitive functional area;

[0009] Multiple connection wire windings; the connection wire windings at least pass through the first display area, and one connection wire winding is used to electrically connect the two independent wire routing parts corresponding to one first-type signal line.

[0010] On the other hand, the present invention provides a display device, including the display panel provided in any embodiment of the present invention.

[0011] The display panel provided by the embodiment of the present invention includes a first photosensitive functional area and a second photosensitive functional area arranged side by side in a first direction, and the length of the first photosensitive functional area in the first direction is greater than the length of the second photosensitive functional area in the first direction, so that the number of the first type of signal lines separated into two independent routing sections is relatively large. In this application, by adding a connecting winding, two independent routing sections corresponding to one first type of signal line are electrically connected by one connecting winding, so that the normal transmission of the first signal on the first type of signal line can be realized. In addition, by setting that the connecting winding passes through at least the first display area, at least part of the connecting winding can be accommodated by the first display area, so that the border area around the first photosensitive functional area and the second photosensitive functional area can be reduced, and the influence on the screen occupation ratio of the display panel can be reduced.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above accompanying drawings 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 under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] To solve the problems described in the background art, an embodiment of the present invention provides a display panel, which includes a first photosensitive functional area, a second photosensitive functional area, a first display area, a second display area, a third display area, a plurality of first type signal lines, and a plurality of connecting winding lines; the first photosensitive functional area and the second photosensitive functional area are arranged side by side along a first direction, and the length of the first photosensitive functional area along the first direction is greater than the length of the second photosensitive functional area along the first direction; the first display area is adjacent to the first photosensitive functional area and the second photosensitive functional area in the first direction respectively, the second display area is adjacent to the first photosensitive functional area in a second direction, and the third display area is adjacent to the second photosensitive functional area in the second direction; at least part of the first type signal lines extends along the second direction, and the first type signal lines are used to transmit a first signal to a pixel circuit; at least part of the first type signal lines in the second display area are separated by the first photosensitive functional area into two independent routing branches, and at least part of the first type signal lines in the third display area are separated by the second photosensitive functional area into two independent routing branches; the connecting winding lines pass through at least the first display area, and one connecting winding line is used to electrically connect the two independent routing branches corresponding to one first type signal line.

[0027] By adopting the above solution, one connecting winding line can be used to electrically connect the two independent routing branches corresponding to one first type signal line, so that the normal transmission of the first signal on the first type signal line can be realized.

[0028] The above is the core idea of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application. Hereinafter, the technical solutions in the embodiments of this application will be described clearly and completely with reference to the accompanying drawings in the embodiments of this application.

[0029] Figure 1 is a schematic structural diagram of a display panel provided by an embodiment of the present invention, as Figure 1As shown in the figure, the display panel 100 provided by the embodiment of the present invention includes a first photosensitive functional area S1, a second photosensitive functional area S2, a first display area A1, a second display area A2, a third display area A3, a plurality of first type signal lines 01, and a plurality of connection winding lines 02; the first photosensitive functional area S1 and the second photosensitive functional area S2 are arranged side by side along a first direction (such as the x direction), and the length of the first photosensitive functional area S1 along the first direction (such as the x direction) is greater than the length of the second photosensitive functional area S2 along the first direction (such as the x direction); the first display area A1 is adjacent to the first photosensitive functional area S1 and the second photosensitive functional area S2 respectively in the first direction (such as the x direction), the second display area A2 is adjacent to the first photosensitive functional area S1 in a second direction (such as the y direction), and the third display area A3 is adjacent to the second photosensitive functional area S2 in the second direction (such as the y direction); at least part of the first type signal lines 01 extend along the second direction (such as the y direction), and the first type signal lines 01 are used to transmit a first signal to a pixel circuit; at least part of the first type signal lines 01 in the second display area A2 are separated into two independent wiring branches by the first photosensitive functional area S1, and at least part of the first type signal lines 01 in the third display area A3 are separated into two independent wiring branches by the second photosensitive functional area S2; the connection winding lines 02 pass through at least the first display area A1, and one connection winding line 02 is used to electrically connect the two independent wiring branches corresponding to one first type signal line 01.

[0030] Among them, both the first photosensitive functional area S1 and the second photosensitive functional area S2 are used to place photosensitive elements. The photosensitive elements can be cameras, fingerprint recognition sensors, distance sensors, infrared sensors, etc., and the embodiment of the present invention does not make special limitations on this. Specifically, through holes corresponding to the respective photosensitive elements in the first photosensitive functional area S1 and the second photosensitive functional area S2 are provided on the back surface of the display panel.

[0031] Optionally, the first photosensitive functional area S1 and the second photosensitive functional area S2 can be non-display areas, that is, the first photosensitive functional area S1 and the second photosensitive functional area S2 do not emit light. In this way, the influence on the use performance of the photosensitive elements can be reduced.

[0032] Such as Figure 2As shown, due to the existence of the first photosensitive functional region S1 and the second photosensitive functional region S2, the display area AA of the display panel 100 can be divided into a first display area A1, a second display area A2, and a third display area A3. Among them, the first display area A1 is adjacent to the first photosensitive functional region S1 in the first direction (such as the x direction), the second display area A2 is adjacent to the first photosensitive functional region S1 in the second direction (such as the y direction), and the third display area A3 is adjacent to the second photosensitive functional region S2 in the second direction (such as the y direction). Specifically, the display area to the left of the reference line L1, the display area between the reference lines L4 and L5, and the display area to the right of the reference line L6 are all the first display area A1. The area between the reference lines L1 and L4 excluding the first photosensitive functional region S1 is the second display area A2, and the area between the reference lines L5 and L6 excluding the second photosensitive functional region S2 is the third display area A3.

[0033] In this embodiment, the first direction is parallel to the arrangement direction of the first photosensitive functional region S1 and the second photosensitive functional region S2, and the specific direction of the first direction can be determined according to the arrangement direction of the two in the actual product. As Figure 1 shown, optionally, the first direction is the row direction x of the display panel 100. Correspondingly, the second direction can be the column direction y of the display panel 100. Of course, in other embodiments, the first direction can be optionally the column direction y of the display panel, and the second direction is the row direction x of the display panel. The embodiments of the present invention do not limit this, and here, the Figure 1 setting method shown, that is, the first direction is the row direction x of the display panel 100, and the second direction is the column direction y of the display panel 100, is taken as an example for illustration.

[0034] The display panel includes a pixel circuit and a light-emitting element. The pixel circuit is used to drive the light-emitting element to emit light. Specifically, the pixel circuit needs to be transmitted with corresponding electrical signals by signal lines to drive the light-emitting element to emit light. According to the panel design, each signal line may extend in different directions. In this embodiment, at least part of the first type of signal line 01 extends along the second direction (such as the y direction). In other words, the first type of signal line 01 may have some broken lines, but generally extends along the second direction (such as the y direction). For different panel designs, at least part of different signal lines extends along the second direction (such as the y direction). Here, the type of the first type of signal line 01 is not specially limited for the time being, and an exemplary description will be given later.

[0035] In this embodiment, since the display panel 100 includes a first photosensitive functional region S1 and a second photosensitive functional region S2 arranged side by side in the first direction (such as the x direction), more first-type signal lines 01 are separated into two independent routing sections by the photosensitive functional regions (i.e., the first photosensitive functional region S1 and the second photosensitive functional region S2). It is necessary to set up winding to achieve their connection and ensure the normal transmission of the first signal on the first-type signal lines 01. Specifically, in this embodiment, the two independent routing sections corresponding to the first-type signal lines 01 are electrically connected by a connecting winding 02, and by setting the connecting winding 02 to pass through at least the first display region A1, the first display region can accommodate at least part of the connecting winding 02, thereby reducing the border area around the first photosensitive functional region S1 and the second photosensitive functional region S2 and reducing the impact of the winding on the screen occupation ratio of the display panel.

[0036] Exemplarily, as Figure 1 shown, the first-type signal lines 01 in the second display region A2 are separated into two independent parts by the first photosensitive functional region S1. By electrically connecting these two parts with the connecting winding 02, the normal transmission of the first signal on the first-type signal lines 01 can be achieved. Figure 1 Only two first-type signal lines 01 in the second display region A2 are shown. Specifically, connecting windings 02 corresponding to the second display region A2 are provided in the regions F1 and F2 in the first display region A1 to connect the first-type signal lines 01 separated into two parts by the first photosensitive functional region S1. Similarly, a connecting winding 02 corresponding to the third display region A3 is provided in the region F3 in the first display region A1 to connect the first-type signal lines 01 separated into two parts by the second photosensitive functional region S2.

[0037] In summary, the display panel provided by the embodiment of the present invention includes a first photosensitive functional region and a second photosensitive functional region arranged side by side in the first direction, and the length of the first photosensitive functional region in the first direction is greater than the length of the second photosensitive functional region in the first direction, so that the number of first-type signal lines separated into two independent routing sections is relatively large. In this application, by adding connecting windings, two independent routing sections corresponding to one first-type signal line are electrically connected by one connecting winding, thereby enabling the normal transmission of the first signal on the first-type signal lines. In addition, by setting the connecting winding to pass through at least the first display region, at least part of the connecting winding can be accommodated by the first display region, thereby reducing the border area around the first photosensitive functional region and the second photosensitive functional region and reducing the impact on the screen occupation ratio of the display panel.

[0038] Based on the above embodiments, in the present application, since the length of the first photosensitive functional region S1 in the first direction (such as the x direction) is greater than the length of the second photosensitive functional region S2 in the first direction (such as the x direction), the number of the first type of signal lines 01 separated into two independent routing branches by the first photosensitive functional region S1 is greater than the number of the first type of signal lines 01 separated into two independent routing branches by the second photosensitive functional region S2. In addition, as Figure 1 shown, the first photosensitive functional region S1 and the second photosensitive functional region S2 are usually close to the boundary (such as the boundary line b) between the display region AA and the non-display region NA. Thus, since the number of winding lines corresponding to the first photosensitive functional region S1 is larger, if only winding from both sides of the first photosensitive functional region S1, it will inevitably occupy a relatively large area of the border region (such as the region between the boundary line b and the boundary line c). On the one hand, it is not conducive to realizing a narrow border. On the other hand, when the size of the border region is fixed, if the winding occupies a relatively large area of the border region, it will not be conducive to the arrangement of other original circuit components in the border region. To further solve this problem, the embodiments of the present invention propose the following solutions.

[0039] Figure 2 FIG. is a schematic structural diagram of another display panel provided by an embodiment of the present invention, Figure 3 is Figure 2 an enlarged structural diagram of the region Q in Figure 4 is Figure 2 another enlarged structural diagram of the region Q in Figures 2 - 4 shown, in the display panel 100 provided by the embodiment of the present invention, along the first direction (such as the x direction), the first photosensitive functional region S1 includes at least two via regions S11 and at least one non-via region S12, and the non-via region S12 is located between two adjacent via regions S11; the second display region A2 includes a first sub-display region A21 and a second sub-display region A22, the first sub-display region A21 is adjacent to the via region S11 in the second direction (such as the y direction), and the second sub-display region A22 is adjacent to the non-via region S12 in the second direction (such as the y direction); the multiple first type of signal lines 01 include multiple first signal lines 11, the first signal lines 11 are located in the first sub-display region A21 and extend along the second direction (such as the y direction), and are separated into a first routing branch 111 and a second routing branch 112 by the via region S11; the first signal lines 11 are used to transmit a first signal to the pixel circuit 20 in the first sub-display region A21; the multiple connection winding lines 02 include multiple second signal lines 12 and multiple third signal lines 13, the second signal lines 12 include a part passing through the second sub-display region A22 and the non-via region S12 and extending along the second direction (such as the y direction), and the third signal lines 13 include a part passing through the first display region A1 and extending along the second direction (such as the y direction); the second signal lines 12 and the third signal lines 13 are respectively electrically connected to the first routing branch 111 and the second routing branch 112 corresponding to different first signal lines 11.

[0040] As shown Figure 2 in the figure, in this embodiment, the first photosensitive functional region S1 includes at least two via regions S11 and at least one non-via region S12, and the non-via region S12 is located between two adjacent via regions S11. Exemplarily, Figure 2 take the first photosensitive functional region S1 including two via regions S11 and one non-via region S12 as an example for illustration. Refer to Figure 2 , specifically, within the first photosensitive functional region S1, the region to the left of the reference line L2 is one of the via regions S11, the region between the reference lines L2 and L3 is the non-via region S12, and the region to the right of the reference line L3 is the other via region S11. In addition, as Figure 2 shown, considering the influence of process precision, the actual size of the optional via (such as H1) is smaller than the area of the corresponding via region S11, Figure 2 and the identification H1 is used to indicate the actual setting position of the via.

[0041] Optionally, the shape of the via H1 can be circular, oval, rectangular, square or any other polygon, and the embodiments of the present invention do not limit this, Figure 2 and only take the shape of the via H1 as circular for illustration.

[0042] Refer to Figure 2 , the second display region A2 can be divided into a first sub-display region A21 and a second sub-display region A22. Among them, the first sub-display region A21 is adjacent to the via region S11 in the second direction (such as the y direction), and the second sub-display region A22 is adjacent to the non-via region S12 in the second direction (such as the y direction). It can be understood that the number of the first sub-display regions A21 in the second display region A2 is the same as the number of the via regions S11 in the first photosensitive functional region S1, and the number of the second sub-display regions A22 in the second display region A2 is the same as the number of the non-via regions S12 in the first photosensitive functional region S1.

[0043] As Figure 2 and Figure 3 shown, pixel circuits 20 are arranged in an array in the display region AA of the display panel 100, and the pixel circuits 20 are used to drive the light-emitting elements to emit light. In addition, a plurality of signal lines are also arranged in the display panel 100, including different types of signal lines such as scan signal lines, data signal lines, and power supply signal lines, which are respectively used to transmit scan signals, data signals, and power supply signals to the pixel circuits 20 to control the working state signals of the pixel circuits, and further control the light-emitting states of the corresponding light-emitting elements.

[0044] Specifically, various signal lines can extend along different directions according to the panel design. Exemplarily, as Figure 3As shown, the scan signal line 30 extends along the row direction x, the data signal line 40 extends along the column direction y, and the power supply signal line (not shown) has a part extending along the row direction x and a part extending along the column direction y, and the two parts are connected to each other to improve the uniformity of the power supply signal. Further, as Figure 3 shown, the same scan signal line 30 can be electrically connected to the pixel circuits 20 in the same row, and the same data signal line 40 can be electrically connected to the pixel circuits 20 in the same column. In this way, the pixel circuits 20 can be sequentially selected through the scan signal line 30, and the data signal can be transmitted to the pixel circuits 20 in the selected state through each data signal line 40 to realize the sequential writing of the data signal row by row.

[0045] Referring to Figure 3 , when the first direction is the row direction x and the second direction is the column direction y, the first signal line 11 extending along the second direction (such as the y direction) in the first sub-display area A21 can be selected as the data signal line, and the first signal is the data signal. In other words, the first signal line 11 is used to transmit the data signal to the pixel circuits 20 in the first sub-display area A21. As Figure 3 shown, due to the existence of the via hole area S11, the first signal line 11 (data signal line) in the first sub-display area A21 is divided into two parts, namely the first wire section 111 and the second wire section 112. To ensure the transmission of the data signal, it is necessary to set up a winding wire to electrically connect the corresponding first wire section 111 and the second wire section 112. Since the first photosensitive functional area S1 includes at least two via hole areas S11 arranged along the first direction (such as the x direction), compared with the photosensitive functional area with a single via hole (such as the second photosensitive functional area S2), the first photosensitive functional area S1 occupies an increased space in the first direction (such as the x direction), and a larger number of first signal lines 11 are divided into two parts, resulting in an increase in the number of winding wires.

[0046] To reduce the area occupied by the winding wires in the border area around the display area, the embodiment of the present invention sets up a second signal line 12 and a third signal line 13 in the display panel 100 to wind the first type of signal lines 01 (i.e., the first signal lines 11) corresponding to the first photosensitive functional area. Specifically, as Figure 4 shown, the second signal line 12 and the third signal line 13 are respectively electrically connected to the first wire section 111 and the second wire section 112 corresponding to different first signal lines 11, so that the first wire section 111 and the corresponding second wire section 112 are connected, thereby ensuring the normal transmission of the first signal by the first signal line 11. Further, as Figure 4As shown, in this embodiment, the second signal line 12 includes a portion extending in the first direction (such as the x direction) and a portion extending in the second direction (such as the y direction). The portion extending in the first direction (such as the x direction) passes through the first sub-display area A21 and extends to the second sub-display area A22, and the portion extending in the second direction (such as the y direction) passes through the second sub-display area A22 and the non-through hole area S12. The third signal line 13 includes a portion extending in the first direction (such as the x direction) and a portion extending in the second direction (such as the y direction). Among them, the portion extending in the first direction (such as the x direction) passes through the first sub-display area A21 and extends to the first display area A1, and the portion extending in the second direction (such as the y direction) is located within the first display area A1. In addition, the first signal lines 11 corresponding to the two through hole areas S11 are both connected by winding around the second signal line 12 and the third signal line 13.

[0047] Referring to Figure 4 , there needs to be a certain distance between adjacent windings (such as the third signal line 13). If the winding is only carried out in the first display area A1, the portion extending horizontally in the winding will occupy a relatively large area of the border area (such as the area between the boundary line b and the boundary line c), which is not conducive to realizing a narrow border. In contrast, in the embodiment of the present invention, by using the non-through hole area S12 to set part of the winding (i.e., the second signal line 12), the area occupied by the portion extending horizontally in the winding in the border area can be reduced or even eliminated, which is conducive to realizing a narrow border.

[0048] It should be noted that in this application, for the expression that the signal line or the trace distribution extends in the second direction (or the first direction), in the drawings, a straight line parallel to this direction is used as an example for the signal line or the trace distribution for illustration. It can be understood that in an actual display panel, the signal line or the trace distribution may not be a straight line, and there may be a certain inclination angle locally.

[0049] Optionally, the first type of signal line 01 and the connection winding 02 are located in different film layers. The connection winding 02 (such as the second signal line 12 and the third signal line 13) is used to connect two separated parts (such as the first trace distribution 111 and the second trace distribution 112 of the first signal line 11) in the first type of signal line 01. Therefore, the connection winding is also used to transmit the first signal. Referring to Figure 4 , the second signal line 12 and the third signal line 13 will pass through other signal lines (such as the following fourth signal line 14 or fifth signal line 15) transmitting the first signal during the winding process. Therefore, by setting the first type of signal line 01 and the connection winding 02 in different film layers, for example, setting the first signal line 11 and the second signal line 12 in different film layers, and setting the first signal line 11 and the third signal line 13 in different film layers, short circuits between different signal lines transmitting the first signal can be avoided, and the normal transmission of the first signal can be ensured.

[0050] Specifically, the conductive layers in the display panel usually include the gate layer and the source-drain layer of thin-film transistors, the capacitor plate layer of storage capacitors, the anode metal layer of light-emitting elements, the interlayer metal layer (the metal layer for transition), etc. Those skilled in the art can set the film layers where the first signal line 11, the second signal line 12, and the third signal line 13 are located according to actual needs, as long as it is ensured that the first signal line 11 and the second signal line 12 are located in different film layers, and the first signal line 11 and the third signal line 13 are located in different film layers. Additionally, the second signal line 12 and the third signal line 13 can be located in the same film layer or in different film layers, and the embodiments of the present invention do not limit this.

[0051] In summary, in the embodiments of the present invention, by setting the second signal line and the third signal line, the second signal line includes a portion that passes through the second sub-display area and the non-through hole area and extends along the second direction, the third signal line includes a portion that passes through the first display area and extends along the second direction, and the second signal line and the third signal line are respectively electrically connected to the first wiring section and the second wiring section corresponding to different first signal lines. The non-through hole area can be used to share part of the wiring for electrically connecting the first wiring section and the second wiring section, that is, the second signal line. Thus, the wiring in the first display area for connecting the first wiring section and the second wiring section, that is, the third signal line, can be reduced, and further, the area occupied by the wiring in the border area can be reduced or even eliminated, realizing a narrow border, or leaving enough space for other circuit elements in the border area.

[0052] Based on the above embodiments, taking the first direction as the row direction x and the second direction as the column direction y as an example, the technical solutions of the embodiments of the present invention will be further described below.

[0053] As Figures 2 - 4 shown, the display panel 100 further includes a substrate 10; the multiple first-type signal lines 01 further include multiple fourth signal lines 14; the fourth signal line 14 passes through the second sub-display area A22 and the non-through hole area S12 and is used to transmit a first signal to the pixel circuit 20 in the second sub-display area A22; the second signal line 12 includes a third wiring section 121 extending along the second direction (such as the y direction), and both the second sub-display area A22 and the non-through hole area S12 include the third wiring section 121; the fourth signal line 14 includes a fourth wiring section 141 extending along the second direction (such as the y direction), and both the second sub-display area A22 and the non-through hole area S12 include the fourth wiring section 141; the orthographic projection of the third wiring section 121 on the substrate 10 does not overlap with the orthographic projection of the fourth wiring section 141 on the substrate 10.

[0054] According to the above description, in this embodiment, the fourth signal line 14 is a data signal line and is used to transmit a data signal to the pixel circuit 20 in the second sub-display area A22.

[0055] AsFigure 4 As shown, in the second signal line 12, the third trace section 121 extends along the second direction (such as the y direction), and both the second sub-display area A22 and the non-through hole area S12 include the third trace section 121. Specifically, the second signal line 12 may include one or more third trace sections 121. When the second signal line 12 includes one third trace section 121, it can be understood that when both the second sub-display area A22 and the non-through hole area S12 include the third trace section 121, a part of the third trace section 121 is located in the second sub-display area A22, and the other part is located in the non-through hole area S12. When the second signal line 12 includes multiple third trace sections 121, it can be understood that when both the second sub-display area A22 and the non-through hole area S12 include the third trace section 121, some of the third trace sections 121 are located in the second sub-display area A22, and the other part of the third trace sections 121 is located in the non-through hole area S12. Exemplarily, Figure 4 Taking the second signal line 12 including one third trace section 121 as an example for illustration. Similarly, for the fourth signal line 14, regarding that both the second display area A2 and the non-through hole area S12 include the fourth trace section 141, it can be understood with reference to the above explanation and will not be elaborated here.

[0056] The fourth signal line 14 is a data signal line. Therefore, in the fourth signal line 14, most of it is the part extending along the second direction (such as the y direction) (i.e., the fourth trace section 141). In this embodiment, by setting the part of the second signal line 12 extending along the second direction (such as the y direction) (i.e., the third trace section 121) and the fourth trace section 141 not to overlap in the positive projection on the substrate 10, the mutual interference of the signals transmitted on the first signal line 11 and the fourth signal line 14 can be avoided, and the influence on the display effect can be reduced.

[0057] Next, two feasible implementation manners are provided to achieve that the positive projections of the third trace section 121 and the fourth trace section 141 on the substrate 10 do not overlap.

[0058] As a feasible implementation manner, Figure 5 is Figure 4 an enlarged structural schematic diagram of the area Z in, combined with Figure 4 and Figure 5 shown, optionally, within the second sub-display area A22, the positive projection of the third trace section 121 on the substrate 10 is located between the positive projections of two adjacent fourth trace sections 141 on the substrate 10; within the non-through hole area S12, the positive projection of the third trace section 121 on the substrate 10 is located between the positive projections of two adjacent fourth trace sections 141 on the substrate 10.

[0059] Specifically, as Figure 4 and Figure 5As shown, after the second signal line 12 extends from a first trace branch 111 in the first sub-display area A21 along the first direction (such as the x direction) to the second sub-display area A22, it can be changed to continue extending in the second direction (such as the y direction) towards the first photosensitive function area S1, passing through the non-through hole area S12, reaching the second sub-display area A22 on the other side of the first photosensitive function area S1, and then changed to extend along the first direction (such as the opposite direction of x) towards the corresponding second trace branch 112, realizing the electrical connection between the first trace branch 111 and the second trace branch 112. In this example, in the second sub-display area A22 and the non-through hole area S12, by setting the orthographic projection of the third trace branch 121 on the substrate 10 to be located between the orthographic projections of two adjacent fourth trace branches 141 on the substrate 10, the orthographic projections of the third trace branch 121 and the fourth trace branch 141 on the substrate 10 can be avoided from overlapping, reducing the mutual interference of the signals transmitted on the first signal line 11 and the fourth signal line 14.

[0060] As Figure 5 shown, further optionally, in the second sub-display area A22, along the first direction (such as the x direction), the distance D2 between two adjacent third trace branches 121 is equal to the distance D1 between two adjacent fourth trace branches 141; in the non-through hole area S12, along the first direction (such as the x direction), the distance D2 between two adjacent third trace branches 121 is equal to the distance D1 between two adjacent fourth trace branches 141. With such a setting, the third trace branches 121 and the fourth trace branches 141 can be evenly distributed, which is beneficial to reducing the complexity of the panel design. At the same time, the traces in the display area AA are evenly distributed, which can improve the uniformity of the human eye's visual viewing effect.

[0061] As another feasible implementation manner, Figure 6 is Figure 2 an enlarged schematic structural diagram of area Q in Figure 7 is Figure 6 an enlarged schematic structural diagram of area P in Figure 6 and Figure 7 shown, the same as the above embodiment in this embodiment is that in the second sub-display area A22, the orthographic projection of the third trace branch 121 on the substrate 10 is located between the orthographic projections of two adjacent fourth trace branches 141 on the substrate 10, and along the first direction (such as the x direction), the distance D2 between two adjacent third trace branches 121 is equal to the distance D1 between two adjacent fourth trace branches 141. With such a setting, the traces in the display area AA can be evenly distributed, improving the uniformity of the human eye's visual viewing effect, and at the same time, the overlap between the third trace branch 121 and the fourth trace branch 141 in the second sub-display area A22 can be avoided, reducing the mutual interference of the signals transmitted on the first signal line 11 and the fourth signal line 14.

[0062] The difference between this embodiment and the above embodiment is that along the first direction (such as the x direction), the non-through-hole region S12 includes a first sub-region S121, a second sub-region S122, and a third sub-region S123 arranged in sequence; within the non-through-hole region S12, the third wiring section 121 is located in the first sub-region S121 and the third sub-region S123, and the fourth wiring section 141 is located in the second sub-region S122. With such an arrangement, the third wiring section 121 and the fourth wiring section 141 can be divided into different regions of the non-through-hole region S12, avoiding the overlap of the orthographic projections of the third wiring section 121 and the fourth wiring section 141 on the substrate 10. In addition, only part of the third wiring section 121 is adjacent to the fourth wiring section 141, thereby further reducing the interference of the signals transmitted on the third wiring section 121 and the fourth wiring section 141, that is, further reducing the mutual interference of the signals transmitted on the first signal line 11 and the fourth signal line 14.

[0063] As Figure 6 and Figure 7 shown, in this embodiment, the second signal line 12 further includes a first folded line section 123; the first folded line section 123 is located in the non-through-hole region S12, and the extending direction of the first folded line section 123 intersects both the first direction (such as the x direction) and the second direction (such as the y direction); both ends of the first folded line section 123 are connected to the third wiring section 121 within the non-through-hole region S12 and the third wiring section 121 within the second sub-display region A22 respectively; the fourth signal line 14 further includes a second folded line section 142; the second folded line section 142 is located in the non-through-hole region S12, and the extending direction of the second folded line section 142 intersects both the first direction (such as the x direction) and the second direction (such as the y direction); both ends of the second folded line section 142 are connected to the fourth wiring section 141 within the non-through-hole region S12 and the fourth wiring section 141 within the second sub-display region A22 respectively; the extending direction of the first folded line section 123 intersects the extending direction of the second folded line section 142.

[0064] Specifically, within the second sub-display region A22, the third wiring section 121 is located between two adjacent fourth wiring sections 141. Through the first folded line section 123, the second signal line 12 can be dispersed to both sides of the non-through-hole region S12, so that the third wiring section 121 of the non-through-hole region S12 is located in the first sub-region S121 and the third sub-region S123; similarly, through the second folded line section 142, the fourth signal line 14 can be concentrated in the middle region of the non-through-hole region S12.

[0065] As Figure 7As shown, in this embodiment, the distance D3 between two adjacent third trace segments 121 in the first sub-region S121 is less than the distance D2 between two adjacent third trace segments 121 in the second sub-display region A22; the distance D4 between two adjacent fourth trace segments 141 in the second sub-region S122 is less than the distance D1 between two adjacent fourth trace segments 141 in the second sub-display region A22.

[0066] Since the third trace segments 121 are concentrated in the first sub-region S121 and the third sub-region S123, therefore, the distance D3 between two adjacent third trace segments 121 in the first sub-region S121 (the third sub-region S123) is less than the distance D2 between two adjacent third trace segments 121 in the second sub-display region A22. Similarly, the distance D4 between two adjacent fourth trace segments 141 in the second sub-region S122 is less than the distance D1 between two adjacent fourth trace segments 141 in the second sub-display region A22. In addition, the non-through hole region S12 only includes traces for transmitting required signals for the pixel circuits in the second sub-display region A22, such as the fourth signal line 14, and does not include structures such as pixel circuits and light-emitting elements, and has a relatively large free space. Therefore, the process of separately arranging the third trace segments 121 and the fourth trace segments 141 in different regions of the non-through hole region S12 has a relatively low difficulty.

[0067] In summary, the above embodiments have described in detail the feasible arrangement methods for the third trace segments 121 and the fourth trace segments 141. The following further describes the remaining parts of the second signal line 12 and the third signal line 13.

[0068] See Figure 3 and Figure 7 Optionally, the second signal line 12 includes a fifth trace segment 122 extending along the first direction (such as the x direction); in the second display region A2, the distance D5 between two adjacent fifth trace segments 122 is equal to the distance C1 between the geometric centers of two adjacent pixel circuit setting regions along the second direction (such as the y direction).

[0069] Figure 8 is Figure 4 a schematic enlarged structure diagram of the G region in Figure 4 and Figure 8 As shown, the third signal line 13 includes a sixth trace segment 131 extending along the first direction (such as the x direction) and a seventh trace segment 132 extending along the second direction (such as the y direction); in the first display region A1, the distance D6 between two adjacent sixth trace segments 131 is equal to the distance C1 between the geometric centers of two adjacent pixel circuit setting regions along the second direction (such as the y direction), and the distance D7 between two adjacent seventh trace segments 132 is equal to the distance C2 between the geometric centers of two adjacent pixel circuit setting regions along the first direction (such as the x direction).

[0070] As Figure 3 shown, the pixel circuit setting area is the setting area of the pixel circuit 20. As described above, in the display panel 100, the pixel circuits 20 are arranged in an array, and the structures of the individual pixel circuits 20 are the same. Therefore, the distance C1 between the geometric centers of two adjacent pixel circuit setting areas in the second direction (such as the y direction) can be understood as the distance between the same circuit structures in two adjacent pixel circuits 20 in the second direction (such as the y direction). For example, the distance between two identical scan signal lines 30 in the second direction (such as the y direction); similarly, the distance C2 between the geometric centers of two adjacent pixel circuit setting areas in the first direction (such as the x direction) can be understood as the distance between the same circuit structures in two adjacent pixel circuits 20 in the first direction (such as the x direction). For example, the distance between two identical data signal lines 40 in the first direction (such as the x direction).

[0071] In this embodiment, by setting the distance C5 between two adjacent fifth trace portions 122 in the second display area A2 to be equal to the distance C1 between the geometric centers of two adjacent pixel circuit setting areas in the second direction (such as the y direction), the distance D6 between two adjacent sixth trace portions 131 in the first display area A1 to be equal to the distance C1 between the geometric centers of two adjacent pixel circuit setting areas in the second direction (such as the y direction), and the distance D7 between two adjacent seventh trace portions 132 to be equal to the distance C2 between the geometric centers of two adjacent pixel circuit setting areas in the first direction (such as the x direction), the newly added fifth trace portions 122, sixth trace portions 131, and seventh trace portions 132 in the display area can be more evenly distributed in the display panel with the original circuit structure, improving the uniformity of the visual viewing effect of the human eye.

[0072] As Figure 4 and Figure 8 shown, optionally, the multiple first type signal lines 01 further include multiple fifth signal lines 15; the fifth signal lines 15 are located in the first display area A1 and extend in the second direction (such as the y direction), and the fifth signal lines 15 are used to transmit a first signal to the pixel circuits in the first display area A1; the seventh trace portion 132 is located between two adjacent fifth signal lines 15.

[0073] Specifically, the fifth signal lines 15 can be used to transmit data signals to the pixel circuits in the first display area A1. In this embodiment, by setting the seventh trace portion 132 to be located between two adjacent fifth signal lines 15, the seventh trace portion 132 and the fifth signal lines 15 can be evenly distributed, further improving the uniformity of the visual viewing effect of the human eye. In addition, it can also avoid the positive projection of the fifth signal lines 15 and the seventh trace portion 132 on the substrate 10 from overlapping, reducing the interference of the signals transmitted on the third signal lines 13 and the fifth signal lines 15.

[0074] AsFigure 4 and Figure 8 As shown, optionally, the display panel further includes a first border area (such as the area between boundary line b and boundary line c), and the first border area includes a fifth wiring section 122 and / or a sixth wiring section 131; the distance between two adjacent fifth wiring sections 122 in the first border area is less than the distance between two adjacent fifth wiring sections 122 in the second display area A2; the distance D8 between two adjacent sixth wiring sections 131 in the first border area is less than the distance D6 between two adjacent sixth wiring sections 131 in the first display area A1.

[0075] As described above, the first photosensitive functional area S1 is usually disposed near the boundary between the display area AA and the non-display area NA (such as boundary line b), and the first border area refers to the non-display area along the second direction (such as the y direction) close to the first photosensitive functional area S1, such as Figure 4 the area between boundary line b and boundary line c in. Due to the large number of winding lines, therefore, there may be some fifth wiring sections 122 and / or sixth wiring sections 131 that need to be wired in the first border area. However, compared with the case where all the winding lines are disposed in the first display area A1, in this embodiment, by disposing the second signal line 12 in the non-through hole area S12, part of the winding lines in the first display area A1 can be shared, thereby reducing the occupation of the first border area by the fifth wiring section 122 and the sixth wiring section 131.

[0076] Exemplarily, Figure 4 taking the first border area including the sixth wiring section 131 as an example for illustration, as Figure 8 shown, the distance D8 between two adjacent sixth wiring sections 131 in the first border area is less than the distance D6 between two adjacent sixth wiring sections 131 in the first display area A1. With such a setting, the area occupation of the sixth wiring section 131 in the first border area can be further compressed, which is beneficial to realizing a narrow border. Similarly, if the first border area includes the fifth wiring section 122, the distance between two adjacent fifth wiring sections 122 in the first border area can be set to be less than the distance between two adjacent fifth wiring sections 122 in the second display area A2.

[0077] In summary, in the above embodiment, taking the first direction as the row direction x of the display panel and the second direction as the column direction y of the display panel as an example, the setting methods of the second signal line 12 and the third signal line 13 are described in detail. As described above, in other embodiments, the through hole area S11 of the first photosensitive functional area S1 is disposed along the column direction y of the display panel. At this time, the first direction is the column direction y of the display panel, and the second direction is the row direction x of the display panel. Exemplarily, Figure 9 is a schematic structural diagram of another display panel provided by an embodiment of the present invention, such as Figure 9As shown, along the y-direction (the first direction), the first photosensitive functional region S1 includes two via regions S11 and one non-via region S12, and the non-via region S12 is located between two adjacent via regions S11.

[0078] Based on the above description, referring to Figure 3 and Figure 9 , in this embodiment, when the first direction is the column direction y, the first photosensitive functional region S1 occupies a relatively large area along the column direction y, so that more signal lines (such as the scanning signal lines 30) extending along the row direction x in the first sub-display region A21 are separated into two independent parts (such as the first scanning line part 301 and the second scanning line part 302) by the via regions S11, and it is necessary to connect these two parts by wire winding. At this time, the first signal line 11 can be selected as the scanning signal line, and the first signal is the scanning signal.

[0079] It can be understood that if only the first display region A1 is used for wire winding, due to the large number of wire windings, a relatively large area of the left border region (such as the region between the boundary lines m and n) is occupied. By adopting the technical solution of the embodiment of the present invention and using the non-via region S12 to share part of the wire winding, the area occupation of the left border region can be reduced, and a narrow border can be achieved. In this embodiment, the specific setting manners of the second signal line 12 and the third signal line 13 can refer to the above embodiment, and will not be elaborated here. In addition, the connection wire winding 02 corresponding to the second photosensitive functional region S2 can be set with reference to the connection wire winding 02 passing through the first display region A1 corresponding to the first photosensitive functional region, and will not be elaborated here.

[0080] Based on the same inventive concept, an embodiment of the present invention further provides a display device, Figure 10 is a schematic structural diagram of a display device provided by an embodiment of the present invention. The display device 200 includes the display panel 100 provided in any of the above embodiments, and thus has the same beneficial effects as the above display panel. The same parts can refer to the description of the above display panel embodiment and will not be elaborated here. The display device 200 provided by the embodiment of the present invention can be Figure 10 the mobile phone shown in the figure, or any electronic product with a display function, including but not limited to the following categories: television, notebook computer, desktop monitor, tablet computer, digital camera, smart bracelet, smart glasses, vehicle-mounted display, medical device, industrial control device, touch interaction terminal, etc. The embodiment of the present invention does not make special limitations on this.

[0081] The above specific implementation manners do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
