DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The figures above already show clear examples of the present application and will be described in detail later. These figures and the written description are not intended to limit the scope of the present application in any manner, but rather to explain the concept of the present application to those skilled in the art by referring to specific examples.

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application are described in more detail below in conjunction with the drawings.

[0027] Currently, in order to increase the screen occupancy rate of the display device, the display panel in the display device can be installed as a display panel with a portion that transmits light. The orthogonal projection of the photosensitive surface of the photosensitive sensor in the display device onto the display panel can be located within the region of the light transmission of the portion, and the photosensitive sensor in the display device is located on the side facing the display surface of the display panel. For example, the following two embodiments can be adopted.

[0028] In the first embodiment, the display panel has a light-transmitting display area and a normal display area. The light-transmitting display area can also be called a full display with camera (FDC) area. A plurality of light-emitting components are installed in both the normal display area and the light-transmitting display area, so that both the normal display area and the light-transmitting display area can display a screen.

[0029] A plurality of light-emitting components located in the light-transmitting display region are coupled in a one-to-one correspondence to some of the plurality of pixel driving circuits in the normal display regions located on both sides of the light-transmitting display region, and the some of the pixel driving circuits are used to control the screen display in the light-transmitting display region.

[0030] Here, the multiple light-emitting components located in the light-transmitting display region can be connected to multiple pixel driving circuits in the corresponding normal display region via multiple connection lines, where a portion of each of the multiple connection lines is located in the light-transmitting display region and another portion is located in the normal display region.

[0031] The light-transmitting display region has a plurality of wiring outlets that are used for extending a plurality of connection lines connecting a plurality of light-emitting components located in the light-transmitting display region from the light-transmitting display region to a position of the normal display region, and the plurality of wiring outlets are located in the light-transmitting display region near edges of the normal display region located on both sides of the light-transmitting display region.

[0032] However, since the pixel driving circuits corresponding to the light-emitting components in the light-transmitting display region of the above-mentioned display panel are located on both sides of the light-transmitting display region, the number of wiring outlets for the connection lines to which the light-emitting components in the light-transmitting display region are connected is reduced, and further the spatial utilization rate of the normal display region around the light-transmitting display region is reduced.

[0033] In the second aspect, the display panel has a display area and a peripheral area located around the display area, and the display area includes a normal display area and a light-transmitting display area. The normal display area has a plurality of pixel driving circuits and a plurality of light-emitting components, and the pixel driving circuit of the normal display area can drive the light-emitting components in the normal display area in a one-to-one correspondence. The light-transmitting display area has a plurality of light-emitting components, but the pixel driving circuits corresponding to the light-emitting components in the light-transmitting display area are located in the peripheral area, and the light-emitting components in the light-transmitting display area are driven by the pixel driving circuits in the peripheral area. This prevents the pixel driving circuits from blocking light rays, and allows the light-transmitting display area to have a light-transmitting function.

[0034] However, since the pixel driving circuit is located in the peripheral region, the frame of the display panel is enlarged, the screen occupancy rate of the display panel is reduced, and the display effect of the display panel is poor.

[0035] Please refer to Fig. 1, which is a schematic diagram of the structure of a display panel 10. The display panel 10 includes a light-transmitting display area 11 and a non-light-transmitting normal display area 12.

[0036] As shown in FIG. 2, FIG. 2 is a schematic diagram of the line connection of the light-transmitting display area and the normal display area of ​​the display panel shown in FIG. 1. A first light-emitting component 111 is installed in the light-transmitting display area 11. A first pixel driving circuit 121 coupled with the first light-emitting component can be installed in the normal display area 12. Here, each first light-emitting component 111 and the corresponding first pixel driving circuit 121 located on both sides of the light-transmitting display area 11 constitute a first pixel unit, and each first light-emitting component 111 can be correspondingly coupled to the first pixel driving circuit 12 located on both sides of the light-transmitting display area 11 via a connecting line 13.

[0037] The normal display area 12 not only includes a plurality of first pixel driving circuits 121, but also includes a plurality of second pixel units (the second pixel units include second light emitting components and second pixel circuits, not shown).

[0038] The light-transmissive display area 11 has a plurality of wiring outlets A1, and a plurality of connection lines 13 connected to the first light-emitting components 111 in one row can extend from the light-transmissive display area 11 through the same wiring outlet A1 and extend to the normal display areas 12 located on both sides of the light-transmissive display area 11. The plurality of wiring outlets A1 are located in the light-transmissive display area 11 close to edges of the normal display areas 12 located on both sides of the light-transmissive display area.

[0039] However, in the above-mentioned display panel 10, the extension directions of the connection lines 13 to which the first light-emitting components 111 located in the light-transmitting display region 11 are connected are all parallel to the row direction of the first light-emitting components 111, so that there is little flexibility in the arrangement of the connection lines 13 corresponding to the first light-emitting components 111 located in the light-transmitting display region 11.

[0040] In addition, since the number of connecting lines 13 arranged in the light-transmissive display region 11 is limited by the peripheral length of the edge of the light-transmissive display region 11, ideally, the connecting lines 13 can be arranged all around the edge of the light-transmissive display region 11 to maximize the use of the wiring arrangement space in the light-transmissive display region 11, but if the connecting lines 13 connected to the first light-emitting components 111 in the light-transmissive display region 11 extend only in the row direction parallel to the first light-emitting components 111 as shown in Fig. 2, the connecting lines 13 are not arranged in the A1 region on the edge of the light-transmissive display region 11. Therefore, the utilization rate of the wiring space in the light-transmissive display region 11 is low.

[0041] Fig. 3 is a plan view of a display panel provided in an embodiment of the present application. Fig. 4 is a schematic diagram of the structure of a portion 20A of the display panel shown in Fig. 3. Fig. 5 is a schematic diagram of a connection structure between a first light-emitting component and a first pixel driving circuit in the light-transmitting display area of ​​the display panel shown in Fig. 3. Please refer to Fig. 3, Fig. 4 and Fig. 5. The display panel 20 may include a substrate 21, a plurality of first light-emitting components 22, a plurality of first pixel driving circuits 23, a plurality of connecting lines 24, a plurality of second pixel driving circuits 25 and a plurality of second light-emitting components 26.

[0042] The substrate 21 may have a light-transmitting display region 211 and a normal display region 212 located around the light-transmitting display region 211. Exemplarily, the normal display region 212 may surround the light-transmitting display region 211, that is, the light-transmitting display region 211 may be surrounded by the normal display region 212. The light-transmitting display region 211 may be located at other positions, and the installation position of the light-transmitting display region 211 may be set as necessary. For example, the light-transmitting display region 211 may be located at a center position on the top of the substrate 21, or at an upper left corner position or an upper right corner position of the substrate 21. Hardware such as a photosensitive sensor (e.g., a camera) may be installed in the light-transmitting display region 211 of the display panel 20. The light-transmitting display region 211 may be circular as shown in FIG. 3, rectangular, or other shapes such as a hexagon or a trapezoid, and the embodiment of the present application is not limited thereto.

[0043] The plurality of first light-emitting components 22 may be located in the light-transmitting display region 211, the plurality of first pixel driving circuits 23 may be located in the normal display region 212, the plurality of connecting lines 24 may be located on the substrate 21, some of the connecting lines 24 may be located in the light-transmitting display region 211, and the other part may be located in the normal display region 212. That is, the plurality of connecting lines 24 coupled to the plurality of light-emitting components 22 located in the light-transmitting display region 211 may extend from the light-transmitting display region 211 through the edge of the light-transmitting display region 211 to the normal display region 212 located around the light-transmitting display region 211. The plurality of first pixel driving circuits 23 are coupled to the plurality of first light-emitting components 22 via the plurality of connecting lines 24, and the plurality of first pixel driving circuits 23 are arranged to drive the emission of the plurality of first light-emitting components 22.

[0044] The plurality of second light emitting components 26 and the plurality of second pixel driving circuits 25 may be located within the normal display area 212. The plurality of second pixel driving circuits 25 are coupled to the plurality of second light emitting components 26, and the plurality of second pixel driving circuits 25 are arranged to drive the plurality of second light emitting components 26 to emit light.

[0045] Here, the multiple first light-emitting components 22 include multiple sets of first light-emitting components 22a extending along a first direction f1 and arranged along a second direction f2, and the extension direction of at least a portion of a line segment of at least one of the multiple connecting lines 24 located within the light-transmitting display area 211 has an acute included angle α with the first direction f1, and the first direction f1 intersects with the second direction f2.

[0046] 5, the first direction f1 does not have to indicate a particular absolute direction. Since the normal display area 212 can surround the light-transmitting display area 211, the first pixel driving circuits 23 can be positioned around the light-transmitting display area 211, and the first pixel driving circuits 23 can also be positioned around the first light-emitting components 22. The first direction f1 can indicate the row direction or column direction of the first light-emitting components 22 in FIG. 4. For example, the light-transmitting display region 211 shown in FIG. 5 includes four light-transmitting divisions 2111 (the four light-transmitting divisions 2111 may be a first light-transmitting division 211a, a second light-transmitting division 211b, a third light-transmitting division 211c, and a fourth light-transmitting division 211d) arranged around the center of the light-transmitting display region 211, and the arrangement of the connecting lines 24 in the first light-transmitting division 211a and the second light-transmitting division 211b may be symmetrical along a symmetry axis s1 of the light-transmitting display region 211, and the included angle between the symmetry axis s1 and the first direction f1 may be 45 degrees, and the first direction f1 in the first light-transmitting division 211a and the second light-transmitting division 211b may be symmetrical along the symmetry axis s1. For example, the first direction f1 in the first light-transmitting division 211a may be a row direction of the plurality of first light-emitting components 22, and the first direction f1 in the second light-transmitting division 211b may be a column direction of the plurality of first light-emitting components 22. Although the embodiment of the present application is described using the first light-transmitting division 211a as an example, the arrangement of the connecting lines 24 in the other light-transmitting divisions may be symmetrical along the symmetry axis of the light-transmitting display region 211 to the arrangement of the connecting lines 24 in the first light-transmitting division 211a.

[0047] In this way, by setting the value of the acute included angle α, the extension direction of at least one connecting line 24 can be flexibly adjusted, the multiple connecting lines 24 can be flexibly arranged, and the arrangement form of the multiple connecting lines 24 on the display panel 20 can be made more flexible.

[0048] In addition, in Figures 4 and 5, in order to make it easier to distinguish between the light-transmitting display area 211 and the normal display area 212, the light-emitting components at the boundary between the light-transmitting display area 211 and the normal display area 212 are not completely illustrated. An actual display panel may have multiple light-emitting components at the boundary between the light-transmitting display area 211 and the normal display area 212, and the multiple light-emitting components may belong to the light-transmitting display area 211 or the normal display area 212.

[0049] For example, the portion of each connecting line 24 located in the light-transmitting display area 211 may be made of a light-transmitting conductive material. In this way, the light transmittance of the light-transmitting display area 211 may be improved. In order to simplify the manufacturing process of the connecting lines 24, the connecting lines 24 may all be made of a light-transmitting conductive material. Here, the light-transmitting conductive material may be indium tin oxide (ITO).

[0050] As described above, an embodiment of the present application provides a display panel, which includes a substrate, a plurality of first light-emitting components, a plurality of first pixel driving circuits, a plurality of connecting lines, a plurality of second light-emitting components, and a plurality of second pixel driving circuits located on the substrate. The plurality of first light-emitting components located in the light-transmitting display region are coupled to the plurality of first pixel driving circuits located in the normal display region through the plurality of connecting lines. Here, the extension direction of at least a portion of the line segments located in the light-transmitting display region of at least one of the plurality of connecting lines has an acute angle with the first direction, so that the plurality of connecting lines can be flexibly arranged by setting the value of the acute angle, and the arrangement form of the plurality of connecting lines on the display panel can be made flexible. This solves the problem of low flexibility in the arrangement form of the connecting lines corresponding to the first light-emitting components located in the light-transmitting display region in the related art, and realizes the effect of improving the flexibility of the arrangement of the connecting lines corresponding to the first light-emitting components located in the light-transmitting display region.

[0051] 4 and 5 show only some of the first light-emitting components 22 in the light-transmitting display region 211 and the wiring patterns of the corresponding connecting lines 24. The wiring pattern of the connecting lines 24 corresponding to at least one other first light-emitting component 22 located in the light-transmitting display region 211 may be similar to this wiring pattern.

[0052] Here, in the embodiment of the present application, the first light-emitting component 22 and the second light-emitting component 26 may be organic light-emitting diode (OLED) light-emitting components. The light-emitting component 22 may include a first electrode, a light-emitting material layer and a second electrode, which are layered and arranged perpendicular to the substrate 21 and away from the substrate 21. The first electrode may be the anode of the light-emitting component 22, and the second electrode may be the cathode of the light-emitting component 22, and the cathode may be a full-layer structure.

[0053] A first electrode of the first light-emitting component 22 may be coupled to a connecting line 24 and coupled to a corresponding pixel driving circuit via the connecting line 24. For the first light-emitting component 22 in FIG. 5, the first light-emitting component 22 is indicated by a connection position of the first light-emitting component 22. The connection position may refer to the connection position between the first electrode of the first light-emitting component 22 and the connecting line 24.

[0054] As an option, as shown in FIG. 6, FIG. 6 is a schematic diagram of a connection line structure of a light-transmitting section provided in an embodiment of the present application. In FIG. 6, in order to easily show the connection form of a plurality of first light-emitting components 22, only one light-transmitting section 2111 of the plurality of light-transmitting sections 2111 is shown, and the connection form of the other light-transmitting sections 2111 is the same as the connection form of the light-transmitting section 2111 shown in FIG. 6. The plurality of first light-emitting components 22 can be coupled to the plurality of first pixel driving circuits 23 in a one-to-one correspondence through a plurality of connecting lines 24. That is, one end of each connecting line 24 can be coupled to one first light-emitting component 22 located in the light-transmitting display area 211, and the other end can be coupled to one first pixel driving circuit 23 located in the normal display area 212. In this way, each first light-emitting component 22 can be coupled to one first pixel driving circuit 23 through one connecting line 24.

[0055] As an option, at least two of the plurality of first light-emitting components 22 can be coupled to one of the plurality of first pixel driving circuits 23 via at least two connecting lines 24. That is, one end of the at least two connecting lines 24 can be coupled to the at least two first light-emitting components 22 located in the light-transmitting display area 211 in a one-to-one correspondence, and the other end of the at least two connecting lines 24 can be coupled to one first pixel driving circuit 23 located in the normal display area 212. In this way, the plurality of first light-emitting components 22 can be coupled to one first pixel driving circuit 23 via the plurality of connecting lines 24. The one first pixel driving circuit 23 can drive the plurality of first light-emitting components 22.

[0056] Alternatively, one first light-emitting component 22 of the multiple first light-emitting components 22 can be coupled to at least two first pixel driving circuits 23 of the multiple first pixel driving circuits 23 via at least two connecting lines 24. In this manner, the first light-emitting component 22 can be coupled to the multiple first pixel driving circuits 23 via the multiple connecting lines 24. The multiple first pixel driving circuits 23 can drive one first light-emitting component 22.

[0057] 6, at least one connecting line 24 may include a first line 241, the first line 241 may include a first line segment 2411 located in the light-transmitting display area 211 and a second line segment 2412 located in the normal display area 212, the first line segment 2411 may be connected to the second line segment 2412, the first line segment 2411 may be coupled to the first light-emitting component 22, and the second line segment 2412 may be coupled to the first pixel driving circuit 23, and the included angle α between the first line segment 2411 and the first direction f1 may be greater than 0 degrees and less than 90 degrees. Alternatively, the included angle between the first line segment 2411 and the first direction f1 may be greater than 30 degrees and less than 70 degrees. In this way, by setting the value of the included angle α between the first line segment 2411 and the first direction f1, the multiple first line segments 2411 can be flexibly arranged, and the arrangement form of the multiple first line segments 2411 on the display panel can be made flexible.

[0058] As an option, the angle between the first line segments 2411 of the first wiring 241 and the first direction f1 may be 45 degrees. In this way, the wiring of the first line segments 2411 of the multiple first wirings 241 located in the light transmissive display 211 can be made relatively uniform and regular.

[0059] As an option, the angle β between the first line segment 2411 of the first wiring 241 and the second line segment 2412 of the first wiring 241 may be greater than 90 degrees. Exemplarily, the angle β between the first line segment 2411 of the first wiring 241 and the second line segment 2412 of the first wiring 241 may be 145 degrees. In this manner, the second line segment 2412 located in the normal display region 212 extends along a direction away from the light-transmitting display region 211 and can be coupled to the first pixel driving circuit 23 located in the normal display region 212.

[0060] In one alternative embodiment, the first wiring 241 may further include a third line segment 2413 located in the light-transmitting display region 211, one end of the third line segment 2413 may be coupled to the first line segment 2411, and the other end of the third line segment 2413 may be coupled to the first light-emitting component 22. The first line segments 2411 may be arranged in parallel along a direction perpendicular to the first line segments 2411 in the light-transmitting display region 211, and the first light-emitting components 22 coupled to the first line segments 2411 may be arranged in a row in the extension direction of the first line segments 2411, so that the distances between the first line segments 2411 arranged in parallel along a direction perpendicular to the first line segment 2411 and the coupled first light-emitting components 22 are different. The first line segments 2411 are coupled to the first light emitting components 22 in a one-to-one correspondence via the third line segments 2314, thereby preventing the first line segments 2411 from overlapping in a direction perpendicular to the substrate 21. Here, the third line segment 2413 may extend along the second direction f2.

[0061] Here, the second line segment 2412 extends along a first direction f1, which may intersect with a second direction f2, and further, the first direction f1 may be perpendicular to the second direction f2.

[0062] 6 , the length of the third line segment 2413 coupled to the first light-emitting components 22 in one of the sets of first light-emitting components 22a is positively correlated with the shortest distance between the third line segment 2413 and the edge of the light-transmitting display area 211. That is, the length of the third line segment 2413 becomes shorter along the direction from the center of the light-transmitting display area 211 to the edge of the light-transmitting display area 211.

[0063] 6, at least one of the connecting lines 24 may further include a second wiring 242, and at least some of the line segments of the second wiring 242 located in the light-transmitting display region 211 may be parallel to the first direction f1. That is, the connecting lines 24 coupled to the first light-emitting components 22 located in the light-transmitting display region 211 may include a first wiring 241 having an extension direction of at least some of the line segments that form an acute angle α with the first direction f1, and may further include a second wiring 242 having an extension direction of at least some of the line segments that are parallel to the first direction f1. This can further improve the wiring flexibility of the connecting lines 24 corresponding to the first light-emitting components 22 located in the light-transmitting display region 211, and the second wiring 242 can be arranged in a wiring space where the first wiring 241 is not arranged, thereby making more efficient use of the wiring space in the light-transmitting display region 211 of the display panel 20.

[0064] For example, as shown in Fig. 7, Fig. 7 is a schematic diagram of the structure of a light-transmitting display area provided in an embodiment of the present application. A plurality of connecting lines 24 corresponding to a plurality of first light-emitting components 22 located in the light-transmitting display area 211 can extend from the light-transmitting display area through the edge of the light-transmitting display area 211, and as can be seen from Fig. 7, the connecting lines 24 can be installed all around the edge of the light-transmitting display area 211, which can improve the utilization rate of the wiring space in the light-transmitting display area 211.

[0065] As an option, as shown in Fig. 8, Fig. 8 is a schematic diagram of a structure of a first light-emitting component located in the light-transmitting display area of ​​the display panel shown in Fig. 7. Among the multiple first light-emitting components 22 located in the light-transmitting display area 211, the connection positions between at least two adjacent first light-emitting components 22 and the connection line 24 can have a predetermined distance in the second direction f2.

[0066] For example, the connection positions between two adjacent first light-emitting components 22 and the connecting line 24 may be a first connection position K1 and a second connection position K2, respectively, and the connection position of one light-emitting component adjacent to the two adjacent first light-emitting components 22 may be K3, and the first connection position K1 and the second connection position K2 have a predetermined distance D1 in the second direction f2, and the third connection position K3 and the second connection position K2 also have a predetermined distance D1 in the second direction f2, where the second direction f2 may be perpendicular to the first direction f1, and thus the wiring space of the connecting line 24 connecting two adjacent first light-emitting components 22 may be the distance D2 between the second connection position K2 and the third connection position K3.

[0067] As shown in Fig. 9, Fig. 9 is a schematic diagram of the structure of a first light-emitting component, in which the connection positions of two adjacent first light-emitting components 22 and the connecting line 24 have a distance of zero in the second direction f2, so that the wiring space of the connecting line 24 connecting two adjacent light-emitting components 22 can be a distance D3 between the second connecting position K2 and the third connecting position K3. Compared with the installation situation of the connecting positions corresponding to the light-emitting components in Fig. 5, D2 is larger than D3, that is, the wiring space of the connecting line 24 between the light-emitting components 22 in the embodiment of the present application is larger.

[0068] In this way, when the extension direction of at least a portion of the line segment of at least one of the multiple connecting lines 24 located within the light-transmitting display region 211 has an acute included angle α with the first direction f1, the wiring space of the connecting line 24 located in the light-transmitting display region 211 is large.

[0069] In one alternative embodiment, as shown in Fig. 10, Fig. 10 is a schematic diagram of a section provided in an embodiment of the present application. The light-transmitting display area 211 may have a plurality of light-transmitting sections 2111, each of which has a plurality of first light-emitting components 22, each of which has the same area, and is arranged around the center of the light-transmitting display area 211. In the light-transmitting section 2111, at least one connecting line 24 coupled to the first light-emitting component 22 extends from the center of the light-transmitting display area 211 to the edge of the light-transmitting display area 211.

[0070] In this way, the number of first light-emitting components 22 in the multiple light-transmitting sections 2111 can be basically the same, so that the difference in length of the connecting lines 24 corresponding to the first light-emitting components 22 in the multiple light-transmitting sections 2111 can be reduced, and the brightness of the first light-emitting components 22 in the multiple light-transmitting sections 2111 of the light-transmitting display area 211 can be made uniform, and the display effect of the light-transmitting display area 211 can be improved.

[0071] For example, the light-transmitting display area 211 may have four light-transmitting divisions 2111, and the shape of the light-transmitting divisions 2111 may be a triangle or a sector. If the shape of the light-transmitting display area 211 is a rectangle, the shape of the light-transmitting divisions 2111 may be a triangle. If the shape of the light-transmitting display area 211 is a circle, the shape of the light-transmitting divisions 2111 may be a sector. The multiple light-transmitting divisions 2111 may be disposed around the center of the light-transmitting display area 211, and the center may refer to the intersection of two diagonals of the light-transmitting display area 211 or the center of a circle.

[0072] As an option, as shown in FIG. 10, the light-transmitting region 2111 may include a first sub-region 211x and a second sub-region 211y defined by a connecting line s2 between the center of the light-transmitting display region 211 and the edge of the light-transmitting display region 211, i.e., the first sub-region 211x and the second sub-region 211y are adjacent to each other.

[0073] The connecting lines 24 of the first light-emitting components 22 located in the first subdivision 211x and the connecting lines 24 of the first light-emitting components 22 located in the second subdivision 211y extend in different directions. For example, the connecting lines 24 of the first light-emitting components 22 located in the first subdivision 211x have an acute included angle α with the first direction f1 of at least one row of the first light-emitting components 22, and the connecting lines 24 of the first light-emitting components 22 located in the second subdivision 211y also have an acute included angle α with the first direction f1 of at least one row of the first light-emitting components 22, so that the included angle between the connecting lines 24 of the first light-emitting components 22 located in the first subdivision 211x and the connecting lines 24 of the first light-emitting components 22 located in the second subdivision 211y may be 2α.

[0074] 10, the connection line s2 between the center of the light-transmitting display region 211 and the edge of the light-transmitting display region 211 is the symmetry axis of the light-transmitting region 2111, and thus the first sub-division 211x and the second sub-division 211y in the light-transmitting region 2111 may have the same area, and the number of light-emitting components 22 in the first sub-division 211x and the second sub-division 211y can be basically the same. Therefore, the difference in length of the connection lines 24 corresponding to the light-emitting components 22 in the first sub-division 211x and the second sub-division 211y can be reduced, and the brightness of the light-emitting components 22 in the first sub-division 211x and the second sub-division 211y of the light-transmitting display region 211 can be made uniform, thereby improving the display effect of the light-transmitting display region 211.

[0075] The symmetry axis is parallel or perpendicular to the first direction f1. The light-transmitting display region 211 may have a plurality of light-transmitting divisions 2111, and the symmetry axes of the light-transmitting divisions 2111 may be parallel or perpendicular to each other, so that the layout of the wirings 24 in the light-transmitting display region 211 can be regular.

[0076] 7, the light-transmitting section 2111 may include a parallel connection region C1 and a diagonal connection region C2 located away from the center of the parallel connection region C1. At least one first light-emitting component 22 located in the parallel connection region C1 may be coupled to the second wiring 242, and at least one first light-emitting component 22 located in the diagonal connection region C2 may be coupled to the first wiring 241. Among the plurality of first light-emitting components 22, the first light-emitting component 22 close to the center of the light-transmitting display region 211 may be coupled to the second wiring.

[0077] The light-transmitting region 2111 may include a first sub-region 211x and a second sub-region 211y, and the light-transmitting region 2111 may further include a parallel connection region C1 and a diagonal connection region C2, which may be understood as two division modes of the light-transmitting region 2111, and the two division modes may simultaneously exist in the light-transmitting region 2111. For example, the first sub-region 211x may include a first parallel connection region and a first diagonal connection region, and the second sub-region 211y may include a second parallel connection region and a second diagonal connection region.

[0078] 7, the first wiring 241 connected to the first light-emitting component 22 located in the diagonal connection region C2 extends from the center of the light-transmitting display region 211 to the edge of the light-transmitting display region 211. In this way, a partial region where no diagonal connecting line is arranged may exist near the symmetric axis in the light-transmitting division 2111, and the region E1 in FIG. 7 may be used to arrange the second wiring 242 connected to the first light-emitting component 22 in the parallel connection region C1. In this way, the wiring space in the light-transmitting display region 211 can be utilized rationally, and more connecting lines 24 can be arranged in the same light-transmitting display region 211 than in the case of unidirectional wiring.

[0079] As an option, refer to Figures 11, 12, 13 and 14, where Figure 11 is a schematic diagram of another display panel structure provided in the embodiment of the present application, and Figures 12, 13 and 14 are schematic diagrams of other three light-transmitting display regions shown in the embodiment of the present application. In addition, in Figures 12, 13 and 14, the connection lines of different layers are divided into three schematic diagrams in order to easily show the positions of the first light-emitting components connected to the connection lines of each structural layer. The multiple first light-emitting components 22 may include multiple sets of first light-emitting components 22a, and the first light-emitting components 22a of each set of the multiple sets of first light-emitting components 22a may extend along the third direction f3, and the multiple sets of first light-emitting components 22a may be arranged along the fourth direction f4, and the first direction f1, the second direction f2, the third direction f3 and the fourth direction f4 may not overlap.

[0080] One set of first light-emitting components 22a among the multiple sets of first light-emitting components 22a may include at least two light-emitting units arranged along the third direction f3, the light-emitting unit may include at least one first light-emitting component 22, and the at least two light-emitting units may each be coupled to a connecting line 24 located in a different layer.

[0081] In addition, in the embodiment of the present application, the at least two light-emitting units are described as including the first light-emitting unit 22a1, the second light-emitting unit 22a2, and the third light-emitting unit 22a3, but the at least two light-emitting units may further include other light-emitting units, and the embodiment of the present application is not limited thereto. Here, the first wirings 241 connected to the first light-emitting unit 22a1, the second light-emitting unit 22a2, and the third light-emitting unit 22a3 may be the first connection line set 24a, the second connection line set 24b, and the third connection line set 24c, respectively, and the first connection line set 24a, the second connection line set 24b, and the third connection line set 24c are located in different layers of the substrate, respectively.

[0082] According to the order of the first light-emitting unit 22a1, the second light-emitting unit 22a2, and the third light-emitting unit 22a3, the corresponding first connection line set 24a, the second connection line set 24b, and the third connection line set 24c can be respectively arranged, and the connecting lines in the first connection line set 24a, the second connection line set 24b, and the third connection line set 24c can be the first connection line 241. In this way, the wiring space of the connecting lines 24 can be increased, and the connecting lines 24 located in different layers can have their own wiring space, and more connecting lines 24 can be arranged in a limited space compared to the wiring form of single-layer wiring.

[0083] 12, in a wiring space of one layer in which the first connection wire set 24a is arranged, a partial region E2 in which the first connection wire set 24a is not arranged may exist near the symmetry axis s2 in the light-transmitting section 2111, and the partial region E2 is used for arranging the second wiring 242 in the light-transmitting section 2111. Similarly, as shown in FIG. 13, in a wiring space of one layer in which the second connection wire set 24b is arranged, a partial region E3 in which the second connection wire set 24b is not arranged may exist near the symmetry axis s2 in the light-transmitting section 2111, and the partial region E3 is used for arranging the second wiring 242 in the light-transmitting section 2111. As shown in Figure 14, in a single layer wiring space in which the third connection wire group 24c is arranged, a partial region E4 in which the third connection wire group 24c is not arranged may exist near the symmetry axis s2 in the light-transmitting section 2111, and this partial region E4 is used for arranging the second wiring 242 in the light-transmitting section 2111.

[0084] Here, the relationship in area size between the partial regions is E2>E3>E4. In this manner, many second wirings 242 can be laid out in the partial region E2.

[0085] In one alternative embodiment, as shown in Figures 7 and 8, the first light-emitting components 22 shown in Figure 8 are eight first light-emitting components 22 among the multiple first light-emitting components 22 in the display panel shown in Figure 7, the shape of the light-transmitting display area 211 may be circular, and the shape of the first light-emitting components 22 may be rectangular, that is, the shape of the pixel unit in which the first light-emitting components 22 are located may be rectangular, and the aspect ratio of the rectangle may be 2:1, and the long side of the rectangle is perpendicular to the first direction f1. Note that, the shape of the first light-emitting components 22 in the embodiment of the present application may be at least one of a hexagon, a trapezoid, an ellipse, and a circle. 13 may represent the shape of the pixel unit in which the first light-emitting component 22 is located, or may represent the shape of the anode of the first light-emitting component 22, and the black dot may represent the connection position between the first light-emitting component 22 and the connection line 24. In the embodiment of the present application, in order to easily show the arrangement of the first light-emitting component 22 and the connection line 24, at least some of the drawings show the first light-emitting component 22 by the connection position between the first light-emitting component 22 and the connection line 24 (i.e., black dot). The connection positions between two adjacent first light-emitting components 22 and the connection line 24 may have a predetermined distance X in the second direction f2, and when the distance between the connection positions between the two adjacent first light-emitting components 22 and the connection line 24 in the first direction f1 is Y, the connection line distance between the connection positions between the two adjacent first light-emitting components 22 and the connection line 24 is Z, and Z is equal to the square root of the sum of X and Y. In this way, the wiring space of the connecting line 24 coupled to the first light-emitting component 22 located in the diagonal connection region C2 may be Z, which can increase the wiring space of the connecting line 24 compared to the situation in related technologies where the wiring space is X or Y; and the multiple connecting lines 24 coupled to the multiple first light-emitting components 22 in the light-transmitting display region 211 can be located in different layers, which can further increase the wiring space of the connecting lines 24.

[0086] Since the number of the connecting lines 24 is limited by the wiring space in the light-transmitting display region 211, the number of the light-emitting components 22 corresponding to the connecting lines 24 is limited, and the area of ​​the light-transmitting display region 211 is limited (when the arrangement density of the light-emitting components 22 is unchanged, the greater the number of the light-emitting components 22, the larger the area of ​​the light-transmitting display region 211). Therefore, based on the hierarchical arrangement of the connecting lines 24 and the wiring form of the connecting lines 24 extending along multiple directions, the light-transmitting display region 211 can have a large wiring space, many connecting lines 24 can be arranged, and many first light-emitting components 22 can be installed, which can further release stress and increase the area of ​​the light-transmitting display region 211.

[0087] For example, in a 458 ppi pixel space (the size of the light-emitting components is 27.675 μm×55.35 μm), when the first light-emitting components 22 in the light-transmitting display area 211 are coupled to the first pixel driving circuits 23 on both sides located in the light-transmitting display area 211 only using connecting lines 24 parallel to the first direction f1, 42 columns of the first light-emitting components 22 can be installed in the first direction f1, and the corresponding diameter of the light-transmitting display area 211 is 2.325 mm. When the connecting lines 24 corresponding to the light-emitting components 22 in the light-transmitting display region 211 include the first wiring 241 in the diagonal connection region C2 and the second wiring 242 in the parallel connection region C1, 48 rows of the first light-emitting components 22 can be installed along the first direction f1, and the diameter of the corresponding light-transmitting display region 211 is 3.757 mm. The area of ​​the light-transmitting display region in the embodiment of the present application is increased by 61.5% compared to the area of ​​the light-transmitting display region in a wiring configuration that only adopts connecting lines 24 parallel to the first direction f1.

[0088] As an option, as shown in Figures 15 and 16, Figure 15 is a schematic diagram of wiring of another light-transmitting display area provided in an embodiment of the present application, and Figure 16 is a schematic diagram of a connection structure of the light-transmitting display area shown in Figure 15. The shape of the light-transmitting display area 211 may be an octagon. At least one connecting line 24 further includes a third wiring 243, which may include a fourth line segment 2431, a fifth line segment 2432 and a sixth line segment 3433 located in the light-transmitting display area 211, and a seventh line segment 2434 located in the normal display area 212, where the fourth line segment 2431, the fifth line segment 2432, the sixth line segment 2433 and the seventh line segment 2434 are connected in sequence, the fourth line segment 2431 is coupled to the first light-emitting component 22, the seventh line segment 2434 is coupled to the first pixel driving circuit 23, and the included angle θ1 between the fourth line segment 2431 and the first direction f1 is greater than 0 degrees and less than 90 degrees, and the included angle θ2 between the fifth line segment 2432 and the first direction f1 is greater than 0 degrees and less than 90 degrees. This allows the number of wiring configurations of the connection lines 24 in the light-transmitting display region 211 to be increased, thereby improving the flexibility of the wiring of the connection lines 24 in the light-transmitting display region 211 .

[0089] As an option, the angle θ3 between the fourth line segment 2431 and the fifth line segment 2432 is greater than 45 degrees and less than 135 degrees. Furthermore, the angle θ3 between the fourth line segment 2431 and the fifth line segment 2432 may be 90 degrees. In this way, the wiring of the third wiring 243 in the light transmissive display region 211 can be regular.

[0090] For example, refer to Figures 16, 17 and 18, where Figure 17 is a schematic diagram of a connection line of another light-transmitting display region shown in an embodiment of the present application, and Figure 18 is a schematic diagram of a connection line of another light-transmitting display region shown in an embodiment of the present application. Note that in Figures 16, 17 and 18, in order to clearly show the connection form of a plurality of first light-emitting components 22, only the connection state of the connection lines 24 in a partial region of the light-transmitting display region 211 is shown, and the connection form of the other regions is the same as the connection form shown in the figures.

[0091] In Figures 16, 17 and 18, the first light-emitting components 22 connected to connecting lines 24 in different layers are shown in three drawings, with Figure 16 showing a plurality of first light-emitting components 22 coupled to a plurality of connecting lines 24 located in the first structural layer 201, Figure 17 showing a plurality of first light-emitting components 22 coupled to a plurality of connecting lines 24 located in the second structural layer 202, and Figure 18 showing a plurality of first light-emitting components 22 coupled to a plurality of connecting lines 24 located in the third structural layer 203. The plurality of connecting lines 24 located in the first structural layer 201 may include a first wiring 241 and a third wiring 243, the plurality of connecting lines 24 located in the second structural layer 202 may include a first wiring 241 and a third wiring 243, and the first light-emitting component 22 coupled to the first wiring 241 in the second structural layer 202 may be located on a side closer to the center of the light-transmitting display region 211 of the first light-emitting component 22 coupled to the first wiring 241 in the first structural layer 201. The first light-emitting component 22 coupled to the third wiring 243 in the second structural layer 202 may be located on a side farther from the center of the light-transmitting display region 211 of the first light-emitting component 22 coupled to the third wiring 243 in the first structural layer 201.

[0092] The multiple connecting lines 24 located in the third structural layer 203 may include a first wiring 241, and the first light-emitting component 22 coupled to the first wiring 241 in the third structural layer 203 may be located away from the center of the light-transmitting display area 211 of the first light-emitting component 22 coupled to the third wiring 243 in the second structural layer 202, and may be located closer to the center of the light-transmitting display area 211 of the first light-emitting component 22 coupled to the first wiring 241 in the second structural layer 202.

[0093] In this way, the same structural layer of the display panel 20 can include various types of wiring, which can improve the flexibility of the arrangement of the connecting lines 24 coupled to the first light-emitting components in the light-transmitting display area 211.

[0094] In one alternative embodiment, refer to Fig. 19 and Fig. 20, which are schematic diagrams of the structures of the first light-emitting components in other two display panels provided in the embodiments of the present application. As shown in Fig. 19, among the plurality of first light-emitting components 22 arranged in one row in the light-transmitting display area, the connection positions K between at least two adjacent first light-emitting components 22 and the connecting line may have a distance D4 in the second direction f2, the second direction f2 may be perpendicular to the first direction f1, and the connection positions K are all located at the corners of the first light-emitting components 22.

[0095] As shown in Fig. 20, Fig. 20 shows another installation manner of the connection position K between the first light-emitting component 22 and the connection line 24, and the connection position K can be located at the corner of the first light-emitting component 22. In this way, the connecting line distance between two adjacent first light-emitting components 22 can be increased, and the wiring space of the connection line between the two adjacent first light-emitting components 22 can be increased. Note that, the connection position K between the first light-emitting component 22 and the connection line 24 in the embodiment of the present application is not limited to the installation manner of the connection position K shown in Figs. 8, 19, and 20, and the connection position K may be in another installation manner, and the embodiment of the present application is not limited thereto.

[0096] As an option, as shown in FIG. 10 , the normal display area 212 can have a number of normal sub-areas 2121 arranged around the light-transmitting display area 211 and corresponding one-to-one to the light-transmitting areas 2111, where the normal sub-areas 2121 are adjacent to the corresponding light-transmitting areas 2111.

[0097] At least some edges of the light-transmitting segments 2111 overlap with at least some edges of the corresponding normal sub-segments 2121.

[0098] 4, the arrangement density of the second light-emitting components 26 located in the normal display region 212 is the same as the arrangement density of the first light-emitting components 22 located in the transmissive display region 211. This same arrangement density can mean that the number of second light-emitting components 26 arranged per unit area in the normal display region 212 is the same as the number of first light-emitting components 22 arranged per unit area in the light-transmissive display region 211.

[0099] In this way, the pixel density or image resolution of the normal display region 212 can be made the same as that of the light-transmissive display region 211. The display effect of the normal display region 212 and the display effect of the light-transmissive display region 211 can be made similar to each other.

[0100] Here, pixel per inch (PPI) can also be called pixel density unit, which represents the number of pixels per inch in the display area. Therefore, the higher the PPI value, the richer the details of the display screen.

[0101] Image resolution refers to the amount of information stored in an image. It can be measured by pixels per inch (PPI). The higher the image resolution, the more pixels the image contains, and the clearer the image will be.
