Description

Technical field

[0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. [Background Technology]

[0002] To achieve a full-screen design, a light-transmitting hole corresponding to the camera position is usually placed inside the screen display area. However, based on the existing design, the border around the light-transmitting hole is relatively wide, which seriously affects the full-screen display effect. [Summary of the invention]

[0003] In view of this, embodiments of the present invention provide a display panel and a display device to reduce the width of a frame corresponding to a light-transmitting hole and optimize the display effect.

[0004] In one aspect, an embodiment of the present invention provides a display panel, comprising:

[0005] At least two light-transmitting holes arranged along a first direction and a display area surrounding each of the light-transmitting holes;

[0006] First-category signal lines located in the display area and extending along the first direction, part of the first-category signal lines including a first line segment A and a first line segment B, wherein the first line segment B is located between two adjacent light-transmitting holes, and the first line segment A is located on a side of the outermost light-transmitting hole away from the first line segment B;

[0007] A first connecting line, one end of the first connecting line is electrically connected to one of the first B line segments, the other end of the first connecting line is electrically connected to the first A line segment or another first B line segment, and at least a portion of the first connecting line is located in the display area.

[0008] On the other hand, an embodiment of the present invention provides a display device including the above-mentioned display panel.

[0009] One of the above technical solutions has the following beneficial effects:

[0010] The embodiment of the present invention provides a first connecting line extending at least within the display area. Not only can the first connecting line be used to connect the line segments of the first type of signal line that are cut off on both sides of the light-transmitting hole (a first A line segment and a first B line segment, or two first B line segments) to achieve connectivity of the signal transmission path, but it can also reduce the number of windings required to be set in the first non-display area surrounding the light-transmitting hole, thereby effectively reducing the width of the border around the light-transmitting hole, that is, reducing the area of the non-luminous area between the light-transmitting hole and the display area, thereby effectively improving the full-screen display effect.

[0011] In addition, in an embodiment of the present invention, when any first B line segment is connected to the adjacent first A line segment or first B line segment through a first connecting line, the flexibility of the shift register driving method can be improved without affecting the border width of the light-transmitting hole. For example, the shift register can perform both unilateral driving and bilateral driving on the first type of signal line.

[0075] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0076] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0077] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0078] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0079] As described in the background, placing a light-transmitting hole within the image display area presents the problem of a wide border around the light-transmitting hole. The inventors have discovered that current display panels can adopt either a single-hole or multi-hole design, but when a display panel adopts a multi-hole design, the border width corresponding to the light-transmitting hole becomes even wider.

[0080] like Figure 1 and Figure 2 As shown, Figure 1 This is a partial top view of a display panel in the related art. Figure 2 This is another partial top view of a display panel in the related art. The display panel includes a first type of signal line 101 extending along a first direction x and a second type of signal line 102 extending along a second direction y. The first type of signal line 101 can be used to transmit scanning signals, light-emitting control signals, etc., and the second type of signal line 102 can be used to transmit data signals, etc.

[0081] When the light-transmitting hole 103 is set within the screen display area, some of the first-type signal lines 101 need to be disconnected on both sides of the light-transmitting hole 103 in the first direction x (hereinafter referred to as the left and right sides), and some of the second-type signal lines 102 need to be disconnected on both sides of the light-transmitting hole 103 in the second direction y (hereinafter referred to as the upper and lower sides) to avoid blocking the light-transmitting hole 103.

[0082] When only one light-transmitting hole 103 is provided in the display panel, see Figure 1 For the second-type signal lines 102 that are disconnected at the upper and lower sides of the light-transmitting hole 103, a wire winding 105 is generally provided within the frame 104 corresponding to the light-transmitting hole 103 to connect the two. For the first-type signal lines 101 that are disconnected at the left and right sides of the light-transmitting hole 103, a dual-side drive method using two sets of shift registers can be used to ensure that signals can still be transmitted normally on the first-type signal lines 101 that are disconnected at both sides. Therefore, there is no need to provide a wire winding within the frame 104 to connect the first-type signal lines 101.

[0083] However, when the display panel is provided with a plurality of light-transmitting holes 103 arranged along the first direction x, see Figure 2 Because the area between two adjacent light-transmitting holes 103 is also used for normal display, even if the shift register is driven bilaterally, the portion of the first-class signal lines 101 located between the two adjacent light-transmitting holes 103 must be connected to the surrounding first-class signal lines 101 via the windings 105. This significantly increases the number of windings 105 required within the frame 104, resulting in a very wide frame 104, which seriously affects the full-screen display quality.

[0084] In this regard, an embodiment of the present invention provides a display panel, such as Figure 3 As shown, Figure 3 This is a top view of a display panel provided by an embodiment of the present invention. The display panel includes at least two light-transmitting holes 1 arranged along a first direction x and a display area 2 surrounding each light-transmitting hole 1. Optical components such as cameras are disposed corresponding to the light-transmitting holes 1. The light-transmitting holes 1 may be holes that do not penetrate the display panel or holes that penetrate the display panel.

[0085] like Figure 4 As shown, Figure 4This is a partial top view of a display panel provided in an embodiment of the present invention. The display panel also includes first-type signal lines 3 located in the display area 2 and extending along a first direction x. A portion of the first-type signal lines 3 is arranged in a disconnected manner on both sides of the light-transmitting aperture 1 in the first direction x. The portion of the first-type signal lines 3 includes a first A segment 4 and a first B segment 5. The first B segment 5 is located between two adjacent light-transmitting apertures 1, and the first A segment 4 is located on the side of the outermost light-transmitting aperture 1 away from the first B segment 5. The outermost light-transmitting aperture 1 refers to the first and last light-transmitting apertures 1 of the at least two light-transmitting apertures 1 arranged along the first direction x.

[0086] The display panel further includes a first connection line 6, one end of which is electrically connected to one first B line segment 5, and the other end of which is electrically connected to a first A line segment 4 or another first B line segment 5. Furthermore, at least a portion of the first connection line 6 is located in the display area 2. Exemplarily, in one configuration, each first B line segment 5 is electrically connected to its adjacent first A line segment 4 or first B line segment 5 via a first connection line 6.

[0087] The embodiment of the present invention provides a first connecting line 6 extending at least within the display area 2. Not only can the first connecting line 6 be used to connect the line segments of the first type signal line 3 that are cut off on both sides of the light-transmitting hole 1 (a first A line segment 4 and a first B line segment 5, or two first B line segments 5) to achieve connectivity of the signal transmission path, but also the number of windings required to be set in the first non-display area 7 surrounding the light-transmitting hole 1 for connecting the first type signal line 3 can be reduced, thereby effectively reducing the width of the border around the light-transmitting hole 1, that is, reducing the area of the non-luminous area between the light-transmitting hole 1 and the display area 2, so as to effectively improve the full-screen display effect.

[0088] In addition, in an embodiment of the present invention, when any first B line segment 5 is connected to the adjacent first A line segment 4 or first B line segment 5 through the first connecting line 6, the flexibility of the shift register driving method can be improved without affecting the border width of the light-transmitting hole 1. For example, the shift register can perform both unilateral driving and bilateral driving on the first type of signal line 3.

[0089] In one possible implementation, Figure 5 As shown, Figure 5This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes second-type signal lines 8 located in the display area 2 and extending along the second direction y. A portion of the second-type signal lines 8 is arranged in a disconnected manner on both sides of the light-transmitting hole 1 in the second direction y. The portion of the second-type signal lines 8 includes a second line segment A 9 and a second line segment B 10. The second line segment A 9 and the second line segment B 10 are located on either side of the light-transmitting hole 1 in the second direction y, respectively. The second direction y intersects the first direction x.

[0090] The display panel further includes a second connecting line 11 , two ends of which are electrically connected to the second line segment A 9 and the second line segment B 10 , respectively. At least a portion of the second connecting line 11 is located in the display area 2 .

[0091] By providing a second connecting line 11 extending at least within the display area 2, the embodiment of the present invention can further reduce the number of wires required in the first non-display area 7 to connect to the second-type signal line 8, while ensuring electrical connection between the second line segment A 9 and the second line segment B 10. This further reduces the width of the border around the light-transmitting hole 1. In particular, when neither the first connecting line 3 nor the second-type signal line 8 requires wire winding for electrical connection, no wire winding is required in the first non-display area 7. In this case, the first non-display area 7 can even be eliminated, achieving a borderless design.

[0092] In one possible embodiment, combining Figures 6 to 9 The light-transmitting hole 1 includes a first light-transmitting hole 12 and a second light-transmitting hole 13. The first line segment B 5 located between the first light-transmitting hole 12 and the second light-transmitting hole 13 is electrically connected to the first line segment A 4 or the first line segment B 5 on the other side of the first light-transmitting hole 12 via a first connecting wire 6. The first light-transmitting hole 12 is also electrically connected to the first line segment A 4 or the first line segment B 5 on the other side of the second light-transmitting hole 13 via a first connecting wire 6.

[0093] Taking a display panel including two light-transmitting holes 1, namely a first light-transmitting hole 12 and a second light-transmitting hole 13, as an example, the above-described arrangement allows the first line segment 5 to be connected to the first line segments 4 on either side via two first connecting lines 6. This, on the one hand, improves the flexibility of the shift register in driving the first-type signal lines 3, enabling both unilateral and bilateral driving. On the other hand, even if one of the first connecting lines 6 breaks, disconnecting the signal transmission path on one side of the first line segment 5, the first line segment 5 can still be connected to the first line segment 4 on the other side via another first connecting line 6. The signal transmission path on the other side allows normal signal transmission on the first line segment 5, thereby improving the connection reliability of the first line segment 5.

[0094] In one possible implementation, Figure 6 and Figure 7 As shown, Figure 6 This is another partial top view of the display panel provided by the embodiment of the present invention. Figure 7 for Figure 6 Schematic diagram of the arrangement of the corresponding first connecting line 6 and the second connecting line 11, the first connecting line 6 includes a first connecting line segment 14, a second connecting line segment 15 and a third connecting line segment 16 connected in sequence, wherein the end of the third connecting line segment 16 is electrically connected to the first B line segment 5 between the first light-transmitting hole 12 and the second light-transmitting hole 13, and the two first connecting lines 6 electrically connected to the first B line segment 5 share a third connecting line segment 16.

[0095] When the first line segment 5 is electrically connected to the two first connecting lines 6, respectively, by reusing the third connecting line segment 16 of the two first connecting lines 6, the space required for the third connecting line segment 16 between the first light-transmitting hole 12 and the second light-transmitting hole 13 can be reduced, thereby optimizing the wiring design in the area between the first light-transmitting hole 12 and the second light-transmitting hole 13 and avoiding overly dense wiring between the first light-transmitting hole 12 and the second light-transmitting hole 13. In other words, this arrangement also imposes fewer restrictions on the distance between the first light-transmitting hole 12 and the second light-transmitting hole 13, allowing the first light-transmitting hole 12 and the second light-transmitting hole 13 to be closer together, thereby helping to increase the flexibility of the placement of the first light-transmitting hole 12 and the second light-transmitting hole 13.

[0096] Further, participate again Figure 6 and Figure 7 The display panel further includes a second-type signal line 8 located in the display area 2 and extending along the second direction y. A portion of the second-type signal line 8 includes a second line segment A 9 and a second line segment B 10. The second line segment A 9 and the second line segment B 10 are respectively located on either side of the light-transmitting hole 1 in the second direction y, where the second direction y intersects the first direction x.

[0097] The display panel further includes a second connecting line 11 , two ends of which are electrically connected to the second line segment A 9 and the second line segment B 10 , respectively, and at least a portion of the second connecting line 11 is located in the display area 2 .

[0098] The second connecting lines 11 include at least one second-A connecting line 17, which is electrically connected to the second-type signal lines 8 on both sides of the first light-transmitting hole 12, and at least a portion of the second-A connecting line 17 is located between the first light-transmitting hole 12 and the second light-transmitting hole 13. And / or, the second connecting lines 11 include at least one second-B connecting line 18, which is electrically connected to the second-type signal lines 8 on both sides of the second light-transmitting hole 13, and at least a portion of the second-B connecting line 18 is located between the first light-transmitting hole 12 and the second light-transmitting hole 13.

[0099] When the two first connecting lines 6 electrically connected to the first B line segment 5 share a third connecting line segment 16, the number of third connecting line segments 16 required to be accommodated between the first light-transmitting hole 12 and the second light-transmitting hole 13 is relatively small, thereby freeing up a portion of space to accommodate the second connecting line 11, thereby achieving rational utilization of this portion of space between the first light-transmitting hole 12 and the second light-transmitting hole 13.

[0100] Moreover, when some of the second connecting lines 11 are arranged between the first light-transmitting hole 12 and the second light-transmitting hole 13, it is also helpful to reduce the load difference between different second connecting lines 11. Specifically, taking the part of the second connecting lines 11 electrically connected to the second-type signal lines 8 on both sides of the first light-transmitting hole 12 as an example, in the embodiment of the present invention, when the number of these second connecting lines 11 is certain, by arranging some of the second connecting lines 11 (second A connecting lines 17) between the first light-transmitting hole 12 and the second light-transmitting hole 13, the number of second connecting lines 11 surrounding the first light-transmitting hole 12 on the side of the first light-transmitting hole 12 away from the second light-transmitting hole 13 can be reduced, thereby reducing the difference in extension length between the second connecting lines 11 surrounding the first light-transmitting hole 12 on the outside and the second connecting lines 11 surrounding the first light-transmitting hole 12 on the inside, thereby effectively reducing the load difference between different second connecting lines 11, and helping to improve load uniformity.

[0101] Furthermore, in an embodiment of the present invention, for the second-category signal lines 8 located on both sides of the first light-transmitting hole 12, the second A connecting line 17 can be electrically connected to the second-category signal lines 8 in this part of the second-category signal lines 8 close to the second light-transmitting hole 13; for the second-category signal lines 8 located on both sides of the second light-transmitting hole 13, the second B connecting line 18 can be electrically connected to the second-category signal lines 8 in this part of the second-category signal lines 8 close to the first light-transmitting hole 12, so as to further reduce the extension length and load of the second A connecting line 17 and the second B connecting line 18.

[0102] In one possible implementation, Figure 8 and Figure 9 As shown, Figure 8 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 9 for Figure 8 Schematic diagram of the arrangement of the corresponding first connecting line 6 and the second connecting line 11, the first connecting line 6 includes a first connecting line segment 14, a second connecting line segment 15 and a third connecting line segment 16 connected in sequence, wherein the end of the third connecting line segment 16 is electrically connected to the first B line segment 5 between the first light-transmitting hole 12 and the second light-transmitting hole 13, and the third connecting line segment 16 of the two first connecting lines 6 electrically connected to the first B line segment 5 is arranged at intervals.

[0103] In the above-mentioned setting, the two first connecting lines 6 electrically connected to the first B line segment 5 are independent of each other. Even if the third connecting line segment 16 in one of the first connecting lines 6 is broken, the first B line segment 5 can still be electrically connected to the first A line segment 4 on the other side through the first connecting line 6 where the other third connecting line segment 16 is located, so that it can transmit signals normally, and the connection reliability of the first B line segment 5 is higher.

[0104] Further, see again Figure 8 and Figure 9 The display panel also includes a second type of signal line 8 located in the display area 2 and extending along the second direction y. Part of the second type of signal line 8 includes a second A line segment 9 and a second B line segment 10. The second A line segment 9 and the second B line segment 10 are respectively located on both sides of the light-transmitting hole 1 in the second direction y. The second direction y intersects with the first direction x.

[0105] The display panel further includes a second connecting line 11 , two ends of which are electrically connected to the second line segment A 9 and the second line segment B 10 , respectively, and at least a portion of the second connecting line 11 is located in the display area 2 .

[0106] Among them, the second connecting line 11 electrically connected to the second type signal line 8 on both sides of the first light transparent hole 12 surrounds the first light transparent hole 12 along the side of the first light transparent hole 12 away from the second light transparent hole 13; the second connecting line 11 electrically connected to the second type signal line 8 on both sides of the second light transparent hole 13 surrounds the second light transparent hole 13 along the side of the second light transparent hole 13 away from the first light transparent hole 12.

[0107] When the third connecting line segments 16 in the two first connecting lines 6 electrically connected to the first B line segment 5 are independent of each other, a large number of third connecting line segments 16 need to be accommodated between the first light-transmitting hole 12 and the second light-transmitting hole 13. At this time, by electrically connecting the second connecting line 11 electrically connected to the second type signal lines 8 on both sides of the first light-transmitting hole 12 around the first light-transmitting hole 12 on the side of the first light-transmitting hole 12 away from the second light-transmitting hole 13, and electrically connecting the second type signal lines 8 on both sides of the second light-transmitting hole 13 around the second light-transmitting hole 13 along the side of the second light-transmitting hole 13 away from the first light-transmitting hole 12, the second connecting line 11 can be avoided from occupying space between the first light-transmitting hole 12 and the second light-transmitting hole 13, thereby avoiding an excessive number of connecting lines between the first light-transmitting hole 12 and the second light-transmitting hole 13, which causes signal interference.

[0108] In one possible implementation, see again Figure 6 and Figure 7The first connection lines 6 electrically connected to the first-type signal lines 3 on both sides of the light-transmitting hole 1 and the second connection lines 11 electrically connected to the second-type signal lines 8 on both sides of the light-transmitting hole 1 are the first connection lines 6 and the second connection lines 11 corresponding to the light-transmitting hole 1. For at least some light-transmitting holes 1, the first connection lines 6 corresponding to the light-transmitting hole 1 are located on a side of the second connection lines 11 corresponding to the light-transmitting hole 1 that is away from the light-transmitting hole 1.

[0109] That is, for at least part of the light-transmitting hole 1, the first connecting line 6 corresponding to the light-transmitting hole 1 surrounds the first connecting line 6 and the second connecting line 11 corresponding to the light-transmitting hole 1 on the outside. Exemplarily, in one configuration, the light-transmitting hole 1 includes a first light-transmitting hole 12 and a second light-transmitting hole 13, and the first connecting line 6 corresponding to the first light-transmitting hole 12 is located on a side of the second connecting line 11 corresponding to the first light-transmitting hole 12 away from the first light-transmitting hole 12, and the first connecting line 6 corresponding to the second light-transmitting hole 13 is located on a side of the second connecting line 11 corresponding to the second light-transmitting hole 13 away from the second light-transmitting hole 13.

[0110] It is understandable that the types of signals transmitted on the first type signal line 3 and the second type signal line 8 are different, and the signal differences are also quite large. In the embodiment of the present invention, by arranging the first connecting line 6 corresponding to the light-transmitting hole 1 outside the second connecting line 11, the second connecting line 11 can be concentratedly arranged at a position close to the light-transmitting hole 1, and the first connecting line 6 can be concentrated outside the second connecting line 11 away from the light-transmitting hole 1, thereby reducing the mutual interference between the first connecting line 6 and the second connecting line 11 and improving the reliability of the transmission of different types of signals. Moreover, under this arrangement, the first connecting line 6 and the second connecting line 11 do not overlap. If the first connecting line 6 and the second connecting line 11 are arranged on the same layer, it is more conducive to the wiring design of the two.

[0111] Further, see again Figure 6 and Figure 7 When the first connecting line 6 is located outside the second connecting line 11, the extension length of the first connecting line 6 is relatively large. At this time, the third connecting line segment 16 of the two first connecting lines 6 electrically connected to the first B line segment 5 can be shared. In addition to reducing the space required to be occupied by the third connecting line segment 16 between the two light-transmitting holes 1, it can also reduce the load of the entire routing composed of the first connecting line 6 and the first A line segment 4 and the first B line segment 5 electrically connected thereto.

[0112] In one possible implementation, see again Figure 8 and Figure 9The first connection lines 6 electrically connected to the first-type signal lines 3 on both sides of the light-transmitting hole 1 and the second connection lines 11 electrically connected to the second-type signal lines 8 on both sides of the light-transmitting hole 1 are the first connection lines 6 and the second connection lines 11 corresponding to the light-transmitting hole 1. For at least some of the light-transmitting holes 1, the second connection lines 11 corresponding to the light-transmitting hole 1 are located on a side of the first connection lines 6 corresponding to the light-transmitting hole 1 that is away from the light-transmitting hole 1.

[0113] That is, for at least part of the light-transmitting hole 1, the second connecting line 11 corresponding to the light-transmitting hole 1 surrounds the first connecting line 6 corresponding to the light-transmitting hole 1 on the outside. Exemplarily, in one configuration, the light-transmitting hole 1 includes a first light-transmitting hole 12 and a second light-transmitting hole 13, the second connecting line 11 corresponding to the first light-transmitting hole 12 is located on a side of the first connecting line 6 corresponding to the first light-transmitting hole 12 away from the first light-transmitting hole 12, and the second connecting line 11 corresponding to the second light-transmitting hole 13 is located on a side of the first connecting line 6 corresponding to the second light-transmitting hole 13 away from the second light-transmitting hole 13.

[0114] As previously mentioned, the signals transmitted by the first-type signal lines 3 and the second-type signal lines 8 are quite different. In this embodiment of the present invention, by arranging the second connecting lines 11 corresponding to the light-transmitting holes 1 outside the first connecting lines 6, the first connecting lines 6 can be centrally arranged near the light-transmitting holes 1, and the second connecting lines 11 can be centrally arranged outside the second connecting lines 11 away from the light-transmitting holes 1, thereby reducing mutual interference between the first connecting lines 6 and the second connecting lines 11. Moreover, with this arrangement, the first connecting lines 6 and the second connecting lines 11 do not overlap. If the first connecting lines 6 and the second connecting lines 11 are arranged on the same layer, their wiring design is more convenient.

[0115] Further, see again Figure 8 and Figure 9 When the second connecting line 11 is located outside the first connecting line 6, the extension length of the first connecting line 6 is small and the load is correspondingly small. At this time, the third connecting line segments 16 in the two first connecting lines 6 electrically connected to the first B line segment 5 can be spaced apart from each other.

[0116] In one possible implementation, Figure 10 and Figure 11 As shown, Figure 10 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 11 for Figure 10A schematic diagram illustrating the arrangement of the corresponding first connecting wires 6 and second connecting wires 11 shows that the first connecting wires 6 electrically connected to the first-type signal wires 3 on both sides of the light-transmitting hole 1 and the second connecting wires 11 electrically connected to the second-type signal wires 8 on both sides of the light-transmitting hole 1 are the first connecting wires 6 and second connecting wires 11 corresponding to the light-transmitting hole 1. For at least some light-transmitting holes 1, at least one second connecting wire 11 corresponding to the light-transmitting hole 1 is interspersed between the at least two first connecting wires 6 corresponding to the light-transmitting hole 1, and / or at least one first connecting wire 6 corresponding to the light-transmitting hole 1 is interspersed between the at least two second connecting wires 11 corresponding to the light-transmitting hole 1.

[0117] Exemplarily, in one configuration, the light transmission hole 1 includes a first light transmission hole 12 and a second light transmission hole 13, and at least one second connection line 11 corresponding to the first light transmission hole 12 is interspersed between the at least two first connection lines 6 corresponding to the first light transmission hole 12, and / or, at least one first connection line 6 corresponding to the first light transmission hole 12 is interspersed between the at least two second connection lines 11 corresponding to the first light transmission hole 12. At least one second connection line 11 corresponding to the second light transmission hole 13 is interspersed between the at least two first connection lines 6 corresponding to the second light transmission hole 13, and / or, at least one first connection line 6 corresponding to the second light transmission hole 13 is interspersed between the at least two second connection lines 11 corresponding to the second light transmission hole 13.

[0118] In an embodiment of the present invention, the first-type signal line 3 can be used to transmit a scan signal, reset signal, or light-emitting control signal for driving the pixel circuit. When the first-type signal line 3 transmits these signals, based on the operating principle of the pixel circuit, the voltage of the signal provided by a single first-type signal line 3 does not frequently change within a frame time and can remain at a low or high level for a relatively long period of time. In particular, when the first-type signal line 3 transmits a reset signal, a constant voltage is continuously transmitted on the first-type signal line 3. Therefore, when the first connecting line 6 and the second connecting line 11 are interspersed, the first connecting line 6 can act as a shielding line to reduce mutual interference between adjacent second connecting lines 11.

[0119] In one possible implementation, Figure 12 As shown, Figure 12 This is another partial top view of the display panel provided by an embodiment of the present invention. The display panel also includes a plurality of pixel rows 19 arranged along the second direction y. The pixel rows 19 include a plurality of pixel circuits 20 arranged along the first direction x. The pixel circuits 20 are electrically connected to the first type of signal lines 3. The second direction y intersects with the first direction x.

[0120] The display panel further includes a shift register 21 . The shift register 21 includes a plurality of shift units 22 arranged in cascade. One shift unit 22 is electrically connected to the first type signal line 3 connected to at least two pixel rows 19 .

[0121] Among them, for the first type signal lines 3 located on both sides of the light-transmitting hole 1 and electrically connected to the same shift unit 22, the first A line segment 4 or the first B line segment 5 located on the same side of the same light-transmitting hole 1 in the first type signal lines 3 are electrically connected to the same first connecting line 6.

[0122] Specifically, the light-transmitting hole 1 includes a first side and a second side arranged opposite to each other in the first direction x. For the first-type signal line 3 located on both sides of the light-transmitting hole 1 and electrically connected to the same shift unit 22, the first A line segment 4 or the first B line segment 5 located on the first side of the same light-transmitting hole 1 in the first-type signal line 3 is electrically connected to the same first connecting line 6, and the first A line segment 4 or the first B line segment 5 located on the second side of the same light-transmitting hole 1 in the first-type signal line 3 is also electrically connected to the same first connecting line 6.

[0123] When the first-category signal lines 3 connected to at least two pixel rows 19 are electrically connected to the same shift unit 22, the signals received by these first-category signal lines 3 at the same time are the same. Therefore, when setting the first connecting lines 6 corresponding to these first-category signal lines 3, the embodiment of the present invention connects the first A line segment 4 or the first B line segment 5 located on the same side of the same light-transmitting hole 1 in these first-category signal lines 3 to the same first connecting line 6. In this case, there is no need to set a separate first connecting line 6 for each first-category signal line 3. A single first connecting line 6 can be used to electrically connect multiple first-category signal lines 3. This reduces the number of first connecting lines 6 required in the display panel without affecting the normal signal transmission of the multiple first-category signal lines 3, thereby greatly simplifying the wiring design.

[0124] Furthermore, if Figure 13 As shown, Figure 13 This is another partial top view of the display panel provided by an embodiment of the present invention, in which the first connecting line 6 includes a first connecting line segment 14, a second connecting line segment 15 and a third connecting line segment 16 connected in sequence, wherein the first connecting line segment 14 and the third connecting line segment 16 extend along the second direction y respectively, and the second connecting line segment 15 extends along the first direction x.

[0125] For the first-type signal line 3 located on both sides of the light-transmitting hole 1 and electrically connected to the same shift unit 22, the first A line segment 4 located on the same side of the same light-transmitting hole 1 in the first-type signal line 3 is electrically connected to the same first connecting line segment 14, and the first B line segment 5 located on the same side of the same light-transmitting hole 1 in the first-type signal line 3 is electrically connected to the same third connecting line segment 16 or the first connecting line segment 14.

[0126] Taking the display panel including two light-transmitting holes 1, namely the first light-transmitting hole 12 and the second light-transmitting hole 13, as an example, for the first-type signal lines 3 located on both sides of the light-transmitting hole 1 and electrically connected to the same shift unit 22, the first-type line segments 4 located on the side of the first light-transmitting hole 12 of the at least two first-type signal lines 3 are all electrically connected to the first connecting line segment 14 of a first connecting line 6, the first-type line segments 4 located on the side of the second light-transmitting hole 13 of the at least two first-type signal lines 3 are all electrically connected to the first connecting line segment 14 of another first connecting line 6, and the first-type line segments 5 of the at least two first-type signal lines 3 are all electrically connected to the third connecting line segment 16 of the two first connecting lines 6.

[0127] In the above arrangement, the extension directions of the first connecting line segment 14 and the third connecting line segment 16 intersect with the extension directions of the first line segment A 4 and the first line segment B 5. That is, the first connecting line segment 14 and the third connecting line segment 16 are arranged to intersect with the first line segment A 4 and the first line segment B 5 both horizontally and vertically. In this case, multiple horizontal first line segments 4 can be directly electrically connected to the intersecting longitudinal first connecting line segment 14 through vias, and multiple horizontal first line segments 5 can also be directly electrically connected to the intersecting longitudinal third connecting line segment 16 through vias, eliminating the need for additional connecting wires and simplifying the connection method.

[0128] In one possible implementation, Figure 14 and Figure 15 As shown, Figure 14 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 15 This is a schematic diagram of a connection between the shift register 21 and the first type of signal line 3 provided in an embodiment of the present invention. The pixel circuit 20 includes a driving transistor M0, a gate reset module 23, a data writing module 24, and a threshold compensation module 25. The gate reset module 23 is electrically connected to the first scanning signal line S1, the reset signal line Vref, and the gate of the driving transistor M0, respectively. The data writing module 24 is electrically connected to the second scanning signal line S2, the data line Data, and the first electrode of the driving transistor M0, respectively. The threshold compensation module 25 is electrically connected to the second scanning signal line S2, the second electrode of the driving transistor M0, and the gate of the driving transistor M0, respectively.

[0129] The first type of signal lines 3 include a first scanning signal line S1 and a second scanning signal line S2. The shift register 21 includes a first shift register 26, which includes a plurality of first shift units 27 arranged in cascade. For two adjacent pixel rows 19, the second scanning signal line S2 electrically connected to the preceding pixel row 19 and the first scanning signal line S1 electrically connected to the succeeding pixel row 19 are electrically connected to the same first shift unit 27.

[0130] It should be noted that Figure 15In the figure, the i-th pixel row 19_i is represented by the reference numeral 19_i, and correspondingly, the first scanning signal line S1 and the second scanning signal line S2 electrically connected to the i-th pixel row 19_i are represented by the reference numerals S1_i and S2_i, respectively. In addition, it should be noted that Figure 15 The circuit structure shown is not the complete circuit structure of the pixel circuit 20. Figure 15 The complete circuit structure of the corresponding pixel circuit 20 can be found in Figure 16 .

[0131] like Figure 16 As shown, Figure 16 A schematic diagram of the structure of the pixel circuit 20 provided in an embodiment of the present invention:

[0132] The gate reset module 23 includes a gate reset transistor M1 , a gate of which is electrically connected to the first scan signal line S1 , a first electrode of which is electrically connected to the reset signal line Vref, and a second electrode of which is electrically connected to the gate of the drive transistor M0 .

[0133] The data writing module 24 includes a data writing transistor M2, a gate of which is electrically connected to the second scanning signal line S2, a first electrode of which is electrically connected to the data line Data, and a second electrode of which is electrically connected to the first electrode of the driving transistor M0.

[0134] The threshold compensation module 25 includes a threshold compensation transistor M3, a gate of which is electrically connected to the second scan signal line S2, a first electrode of which is electrically connected to the second electrode of the driving transistor M0, and a second electrode of which is electrically connected to the gate of the driving transistor M0.

[0135] The pixel circuit 20 further includes:

[0136] The anode reset module 28 includes an anode reset transistor M4, a gate of the anode reset transistor M4 is electrically connected to the second scan signal line S2, a first electrode of the anode reset module 28 is electrically connected to the reset signal line Vref, and a second electrode of the anode reset transistor M4 is electrically connected to the anode of the light-emitting element D.

[0137] The first light-emitting control module 29 includes a first light-emitting control transistor M5, a gate of the first light-emitting control transistor M5 is electrically connected to the light-emitting control signal line EM, a first electrode of the first light-emitting control transistor M5 is electrically connected to the power signal line PVDD, and a second electrode of the first light-emitting control transistor M5 is electrically connected to the first electrode of the driving transistor M0.

[0138] The second light-emitting control module 30 includes a second light-emitting control transistor M6, a gate of the first light-emitting control transistor M5 is electrically connected to the light-emitting control signal line EM, a first electrode of the first light-emitting control transistor M5 is electrically connected to the second electrode of the driving transistor M0, and a second electrode of the first light-emitting control transistor M5 is electrically connected to the anode of the light-emitting element D.

[0139] The storage capacitor Cst has a first plate electrically connected to the power signal line PVDD, and a second plate electrically connected to the gate of the driving transistor M0.

[0140] Among them, the above-mentioned driving transistor M0, gate reset transistor M1, data writing transistor M2, threshold compensation transistor M3, anode reset transistor M4, first light emitting control module 29 and second light emitting control transistor M6 can all be p-type low temperature polysilicon (LTPS) transistors.

[0141] like Figure 17 As shown, Figure 17 This is a timing diagram provided by an embodiment of the present invention. The working process of the pixel circuit 20 includes an initialization period t1, a charging period t2 and a light-emitting period t3. It should be noted that, Figure 17 The diagram shows the driving timing of the pixel circuit 20 in the i-th pixel row 19_i and the i+1-th pixel row 19_i+1. The t1_i, t2_i and t3_i marked in the figure correspond to the working period of the pixel circuit 20 in the i-th pixel row 19_i, and the t1_i+1, t2_i+1 and t3_i+1 marked in the figure correspond to the working period of the pixel circuit 20 in the i+1-th pixel row 19_i+1.

[0142] In the initialization period t1_i corresponding to the pixel circuit 20 in the i-th pixel row 19_i, the first scanning signal line S1_i corresponding to the i-th pixel row 19_i provides a low level. In the pixel circuit 20 of the i-th pixel row 19_i, the gate reset transistor M1 writes the reset voltage provided by the reset signal line Vref into the gate of the driving transistor M0, thereby resetting the gate of the driving transistor M0.

[0143] During charging period t2_i corresponding to pixel circuit 20 in i-th pixel row 19_i, second scan signal line S2_i corresponding to i-th pixel row 19_i provides a low level. In pixel circuit 20 in i-th pixel row 19_i, data write transistor M2 writes the data voltage provided by data line Data into the first electrode of drive transistor M0. Threshold compensation transistor M3 writes the data voltage into the gate of drive transistor M0 and performs threshold compensation on drive transistor M0. Simultaneously, anode reset transistor M4 writes the reset voltage provided by reset signal line Vref into the anode of light-emitting element D, thereby resetting the anode of light-emitting element D.

[0144] During this period, since the second scanning signal line S2_i corresponding to the i-th pixel row 19_i and the first scanning signal line S1_i+1 corresponding to the i+1-th pixel row 19_i+1 are electrically connected to the same first shift unit 27, this period is also the initialization period t1_i+1 corresponding to the pixel circuit 20 in the i+1-th pixel row 19_i+1. During this period, in the pixel circuit 20 of the i+1-th pixel row 19_i+1, the gate reset transistor M1 writes the reset voltage provided by the reset signal line Vref into the gate of the driving transistor M0, thereby resetting the gate of the driving transistor M0.

[0145] In the light-emitting period t3_i corresponding to the pixel circuit 20 in the i-th pixel row 19_i, the light-emitting control signal line EM_i corresponding to the i-th pixel row 19_i provides a low level. In the pixel circuit 20 of the i-th pixel row 19_i, the first light-emitting control transistor M5 writes the power supply voltage provided by the power supply signal line PVDD into the first electrode of the driving transistor M0, and the second light-emitting control transistor M6 transmits the driving current converted by the driving transistor M0 according to the power supply voltage and the data voltage to the anode of the light-emitting element D, thereby driving the light-emitting element D to emit light.

[0146] The first portion of this period also corresponds to a charging period t2_i+1 corresponding to the pixel circuit 20 in the i+1th pixel row 19_i+1. During this charging period t2_i+1, the second scanning signal line S2_i+1 corresponding to the i+1th pixel row 19_i+1 provides a low level. The data write transistor M2 of the pixel circuit 20 in the i+1th pixel row 19_i+1 writes the data voltage provided by the data line Data into the first electrode of the drive transistor M0. The threshold compensation transistor M3 of the pixel circuit 20 in the i-th pixel row 19_i writes the data voltage into the gate of the drive transistor M0 and performs threshold compensation on the drive transistor M0. Simultaneously, the anode reset transistor M4 of the pixel circuit 20 in the i+1th pixel row 19_i+1 writes the reset voltage provided by the reset signal line Vref into the anode of the light-emitting element D, thereby resetting the anode of the light-emitting element D.

[0147] In the light-emitting period t3_i+1 corresponding to the pixel circuit 20 in the i+1th pixel row 19_i+1, the light-emitting control signal line EM_i+1 corresponding to the i+1th pixel row 19_i+1 provides a low level. In the pixel circuit 20 of the i+1th pixel row 19_i+1, the first light-emitting control transistor M5 writes the power supply voltage provided by the power supply signal line PVDD into the first electrode of the driving transistor M0, and the second light-emitting control transistor M6 transmits the driving current converted by the driving transistor M0 according to the power supply voltage and the data voltage to the anode of the light-emitting element D, thereby driving the light-emitting element D to emit light.

[0148] For two adjacent pixel rows 19, when the second scanning signal line S2 connected to the previous pixel row 19 and the first scanning signal line S1 connected to the next pixel row 19 are electrically connected to the same first shift unit 27, when the pixel circuit 20 in the previous pixel row 19 performs a charging operation, the pixel circuit 20 in the next pixel row 19 synchronously performs an initialization operation, and the normal operation of multiple pixel rows 19 can still be guaranteed at this time.

[0149] Moreover, by electrically connecting the first scan signal line S1 and the second scan signal line S2 receiving the same signal to the same first connection line 6 , the number of first connection lines 6 required in the display panel can be reduced, thereby simplifying wiring design.

[0150] In one possible implementation, Figure 18 and Figure 19 As shown, Figure 18 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 19 This is another connection diagram of the shift register 21 and the first-class signal line 3 provided in an embodiment of the present invention. The pixel circuit 20 includes a driving transistor M0, a gate reset module 23, a data writing module 24, and a threshold compensation module 25. The gate reset module 23 is electrically connected to the third scan signal line S3, the reset signal line Vref, and the gate of the driving transistor M0, respectively. The data writing module 24 is electrically connected to the fourth scan signal line S4, the data line Data, and the first electrode of the driving transistor M0, respectively. The threshold compensation module 25 is electrically connected to the fifth scan signal line S5, the second electrode of the driving transistor M0, and the gate of the driving transistor M0, respectively.

[0151] The first type signal line 3 includes a third scanning signal line S3, the shift register 21 includes a second shift register 31, the second shift register 31 includes a plurality of second shift units 32 arranged in cascade, and the second shift units 32 are electrically connected to the third scanning signal line S3 connected to at least two pixel rows 19 respectively.

[0152] And / or, the first type signal line 3 includes a fifth scanning signal line S5, the shift register 21 includes a third shift register 33, the third shift register 33 includes a plurality of third shift units 34 arranged in cascade, and the third shift units 34 are respectively electrically connected to the fifth scanning signal line S5 connected to at least two pixel rows 19.

[0153] It should be noted that Figure 19 The diagram does not show the complete circuit structure of the pixel circuit 20. Figure 19 The complete circuit structure of the corresponding pixel circuit 20 can be found in Figure 20 .

[0154] like Figure 20 As shown, Figure 20 Another structural diagram of the pixel circuit 20 provided in an embodiment of the present invention is as follows:

[0155] The gate reset module 23 includes a gate reset transistor M1 , a gate of which is electrically connected to the third scan signal line S3 , a first electrode of which is electrically connected to the reset signal line Vref, and a second electrode of which is electrically connected to the gate of the drive transistor M0 .

[0163] The driving transistor M0, data writing transistor M2, anode reset transistor M4, first light emission control module 29, and second light emission control transistor M6 are all p-type LTPS transistors. The gate reset transistor M1 and threshold compensation transistor M3 can be n-type indium gallium zinc oxide (IGZO) transistors to reduce the effect of leakage current of the gate reset transistor M1 and threshold compensation transistor M3 on the gate potential of the driving transistor M0.

[0164] like Figure 21 As shown, Figure 21 Another timing diagram provided by an embodiment of the present invention, the working process of the pixel circuit 20 includes an initialization period t1, a charging period t2 and a light emitting period t3. It should be noted that, Figure 21 The diagram shows the driving timing of the pixel circuit 20 in the i-th pixel row 19_i and the i+1-th pixel row 19_i+1. The t1_i, t2_i and t3_i marked in the figure represent the working period of the pixel circuit 20 in the i-th pixel row 19_i, and the t1_i+1, t2_i+1 and t3_i+1 marked in the figure represent the working period of the pixel circuit 20 in the i+1-th pixel row 19_i+1.

[0165] In the initialization period t1_i / t1_i+1 corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1, the third scanning signal line S3_i / S3_i+1 corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1 provides a high level, and in the pixel circuit 20 of the i-th pixel row 19_i and the i+1-th pixel row 19_i+1, the gate reset transistor M1 writes the reset voltage provided by the reset signal line Vref into the gate of the driving transistor M0, thereby resetting the gate of the driving transistor M0.

In the pixel circuit 20 of the i-th pixel row 19_i, the data write transistor M2 writes the data voltage provided by the data line Data into the first electrode of the drive transistor M0. The threshold compensation transistor M3 writes the data voltage into the gate of the drive transistor M0 and performs threshold compensation on the drive transistor M0. Simultaneously, the anode reset transistor M4 writes the reset voltage provided by the reset signal line Vref into the anode of the light-emitting element D, thereby resetting the anode of the light-emitting element D.

[0167] During charging period t2_i+1 corresponding to the (i+1)th pixel row 19_i+1, the fourth scan signal line S4_i+1 corresponding to the (i+1)th pixel row 19_i+1 provides a low level, and the fifth scan signal lines S5_i / S5_i+1 corresponding to the (i+1)th pixel row 19_i and the (i+1)th pixel row 19_i+1 provide a high level. In the pixel circuit 20 of the (i+1)th pixel row 19_i+1, the data write transistor M2 writes the data voltage provided by the data line Data into the first electrode of the drive transistor M0. The threshold compensation transistor M3 writes the data voltage into the gate of the drive transistor M0 and performs threshold compensation on the drive transistor M0. Simultaneously, the anode reset transistor M4 writes the reset voltage provided by the reset signal line Vref into the anode of the light-emitting element D, thereby resetting the anode of the light-emitting element D.

[0168] In the light-emitting period t3_i corresponding to the i-th pixel row 19_i, the light-emitting control signal line EM_i corresponding to the i-th pixel row 19_i provides a low level. In the pixel circuit 20 of the i-th pixel row 19_i, the first light-emitting control transistor M5 writes the power supply voltage provided by the power supply signal line PVDD into the first electrode of the driving transistor M0, and the second light-emitting control transistor M6 transmits the driving current converted by the driving transistor M0 according to the power supply voltage and the data voltage to the anode of the light-emitting element D, driving the light-emitting element D to emit light.

[0169] In the light-emitting period t3_i+1 corresponding to the i+1th pixel row 19_i+1, the light-emitting control signal line EM_i+1 corresponding to the i+1th pixel row 19_i+1 provides a low level. In the pixel circuit 20 of the i+1th pixel row 19_i+1, the first light-emitting control transistor M5 writes the power supply voltage provided by the power supply signal line PVDD into the first electrode of the driving transistor M0. The second light-emitting control transistor M6 transmits the driving current converted by the driving transistor M0 according to the power supply voltage and the data voltage to the anode of the light-emitting element D, thereby driving the light-emitting element D to emit light.

[0170] When the second shift unit 32 is electrically connected to the third scan signal line S3 electrically connected to at least two pixel rows 19, and the third shift unit 34 is electrically connected to the fifth scan signal line S5 electrically connected to at least two pixel rows 19, the at least two pixel rows 19 synchronously perform the initialization operation and separately perform the charging operation.

[0171] By electrically connecting the third scan signal line S3 receiving the same signal to the same first connection line 6, and electrically connecting the fifth scan signal line S5 receiving the same signal to the same first connection line 6, the number of first connection lines 6 required to be set in the display panel can be reduced, thereby simplifying the wiring design.

[0172] In addition, see again Figure 18 The first type signal line 3 may also include a fourth scanning signal line S4, and the display panel also includes a sixth shift register 60. The sixth shift register 60 includes a plurality of cascaded sixth shift units 61. One sixth shift unit 61 is electrically connected to one fourth scanning signal line S4. At this time, different fourth scanning signal lines S4 can be electrically connected to different first connecting lines 6.

[0173] In one possible implementation, Figure 22 and Figure 23 As shown, Figure 22 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 23 This is another connection diagram of the shift register 21 and the first type signal line 3 provided in an embodiment of the present invention. The pixel circuit 20 includes a driving transistor M0 and a second light-emitting control module 30, wherein the second light-emitting control module 30 is electrically connected to the light-emitting control signal line EM, the second electrode of the driving transistor M0 and the light-emitting element D, respectively.

[0174] The first signal line 3 includes a light emitting control signal line EM. The shift register 21 includes a fourth shift register 35 including a plurality of fourth shift units 36 arranged in cascade. The fourth shift units 36 are electrically connected to the light emitting control signal lines EM electrically connected to at least two pixel rows 19.

[0175] It should be noted that Figure 23 The diagram does not show the complete circuit structure of the pixel circuit 20. Figure 23 The complete circuit structure of the corresponding pixel circuit 20 can be found in Figure 20 .

[0176] Based on the above structure, Figure 24 As shown, Figure 24Another timing diagram provided by an embodiment of the present invention, the working process of the pixel circuit 20 includes an initialization period t1, a charging period t2 and a light emitting period t3. It should be noted that, Figure 25 Schematic diagram of the driving timing of the pixel circuit 20 in the i-th pixel row 19_i and the i+1-th pixel row 19_i+1. The labeled t1_i, t2_i, and t3_i in the figure represent the operating period of the pixel circuit 20 in the i-th pixel row 19_i, and the labeled t1_i+1, t2_i+1, and t3_i+1 in the figure represent the operating period of the pixel circuit 20 in the i+1-th pixel row 19_i+1. The operating principles of the pixel circuit 20 during the initialization period t1, the charging period t2, and the light-emitting period t3 are the same as those in the above embodiment and will not be repeated here.

[0177] However, it should be emphasized that during the operation of the pixel circuit 20 in the i-th pixel row 19_i and the i+1-th pixel row 19_i+1, when the light-emitting control signal line EM corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1 is electrically connected to the same fourth shift unit 36, the high level of the light-emitting control signal needs to cover the high level of the third scanning signal, the low level of the fourth scanning signal and the high level of the fifth scanning signal corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1 to ensure the normal operation of the pixel circuit 20.

[0178] In the embodiment of the present invention, by electrically connecting the light emitting control signal lines EM receiving the same signal to the same first connecting line 6 , the number of first connecting lines 6 required in the display panel can be reduced, thereby simplifying the wiring design.

[0179] In one possible implementation, Figure 25 and Figure 26 As shown, Figure 25 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 26 This is another connection diagram of the shift register 21 and the first type signal line 3 provided in an embodiment of the present invention. The pixel circuit 20 includes a driving transistor M0 and a bias modulation module 37, wherein the bias modulation module 37 is electrically connected to the sixth scanning signal line S6, the bias signal line DVH and the first electrode of the driving transistor M0, respectively.

[0180] The first type signal line 3 includes the sixth scanning signal line S6. The shift register 21 includes a fifth shift register 38. The fifth shift register 38 includes a plurality of fifth shift units 39 arranged in cascade. The fifth shift units 39 are electrically connected to the sixth scanning signal line S6 electrically connected to at least two pixel rows 19.

[0181] It should be noted that Figure 26The diagram does not show the complete circuit structure of the pixel circuit 20. Figure 26 The complete circuit structure of the corresponding pixel circuit 20 can be found in Figure 27 .

[0182] like Figure 27 As shown, Figure 27 This is another structural diagram of the pixel circuit 20 provided in an embodiment of the present invention. The bias modulation module 37 includes a bias modulation transistor M7, a gate of the bias modulation transistor M7 is electrically connected to the sixth scan signal line S6, a first electrode of the bias modulation transistor M7 is electrically connected to the bias signal line DVH, and a second electrode of the bias modulation transistor M7 is electrically connected to the first electrode of the drive transistor M0.

[0183] In addition, the pixel circuit 20 also includes a gate reset module 23, an anode reset module 28, a data writing module 24, a threshold compensation module 25, a first light-emitting control module 29, a second light-emitting control module 30 and a storage capacitor Cst. The connection method and function of this part of the structure have been described in detail in the above embodiment and will not be repeated here.

[0184] like Figure 28 As shown, Figure 28 In another timing diagram provided by an embodiment of the present invention, the working process of the pixel circuit 20 includes not only the initialization period t1, the charging period t2 and the light emitting period t3, but also the modulation period t4. It should be noted that, Figure 28 Schematic diagram of the driving timing of the pixel circuit 20 in the i-th pixel row 19_i and the i+1-th pixel row 19_i+1. The labeled t1_i, t2_i, t3_i, and t4_i in the figure represent the operating period of the pixel circuit 20 in the i-th pixel row 19_i, and the labeled t1_i+1, t2_i+1, t3_i+1, and t4_i+1 in the figure represent the operating period of the pixel circuit 20 in the i+1-th pixel row 19_i+1. The operating principles of the pixel circuit 20 during the initialization period t1, the charging period t2, and the light-emitting period t3 are the same as those in the above embodiment and will not be repeated here.

[0185] Modulation period t4 is between charging period t2 and light-emitting period t3. During modulation period t4_i / t4_i+1 corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1, the sixth scanning signal line S6 corresponding to the i-th pixel row 19_i and the i+1-th pixel row 19_i+1 provides a low level. In the pixel circuit 20 of the i-th pixel row 19_i and the i+1-th pixel row 19_i+1, the bias modulation transistor M7 writes the bias voltage provided by the bias signal line DVH into the first electrode of the drive transistor M0, thereby adjusting the bias state of the drive transistor M0.

[0186] In the embodiment of the present invention, by electrically connecting the sixth scan signal lines S6 receiving the same signal to the same first connection line 6 , the number of first connection lines 6 required in the display panel can be reduced, thereby simplifying the wiring design.

[0187] In one possible implementation, Figures 29 to 31 As shown, Figure 29 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 30 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 31 This is another partial top view of the display panel provided in an embodiment of the present invention. The display panel also includes a first non-display area 7. The first non-display area 7 surrounds the light-transmitting hole 1 and the display area 2 surrounds the first non-display area 7. The first non-display area 7 can be understood as a frame corresponding to the light-transmitting hole 1.

[0188] The light-transmitting hole 1 includes a racetrack hole 40 , and the racetrack hole 40 includes a first sub-light-transmitting hole 41 and a second sub-light-transmitting hole 42 arranged along a first direction x.

[0189] The second connection lines 11 include at least one second C connection line 43. The second C connection line 43 is electrically connected to the second-type signal lines 8 on both sides of the first sub-light-transmitting aperture 41. The second C connection line 43 is partially located between the first sub-light-transmitting aperture 41 and the second sub-light-transmitting aperture 42. That is, the second C connection line 43 partially extends within the display area 2 and partially extends within the first non-display area 7 between the first sub-light-transmitting aperture 41 and the second sub-light-transmitting aperture 42. The second C connection line 43 surrounds the first sub-light-transmitting aperture 41 between the first sub-light-transmitting aperture 41 and the second sub-light-transmitting aperture 42.

[0190] And / or, the second connection lines 11 include at least one second D connection line 44, which is electrically connected to the second-type signal lines 8 on both sides of the second sub-light-transmitting hole 42, and the second D connection line 44 is partially located between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. That is, the second D connection line 44 partially extends within the display area 2 and partially extends in the first non-display area 7 between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. The second D connection line 44 surrounds the second sub-light-transmitting hole 42 between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42.

[0191] Since the area between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 is a non-screen display area that is not used for screen display, this non-effective area can be rationally utilized by extending a portion of the second C connecting line 43 and / or the second D connecting line 44 between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. Moreover, this arrangement can also reduce the number of second connecting lines 11 surrounding the runway hole 40 on the outside. In this case, the difference in extension length between the second connecting lines 11 surrounding the runway hole 40 on the outside and the second connecting lines 11 surrounding the runway hole 40 on the inside can be reduced, thereby effectively reducing the load difference between different second connecting lines 11, which helps to improve load uniformity.

[0192] Furthermore, when portions of second C connecting line 43 and / or second D connecting line 44 extend between first sub-light-transmitting aperture 41 and second sub-light-transmitting aperture 42, second C connecting line 43 and / or second D connecting line 44 do not need to wrap around the outside of runway aperture 40, thus shortening their extension length and correspondingly reducing their load. This reduces the load differences between the overall routing formed by second C connecting line 43 and its connected second A line segment 9 and second B line segment 10, the overall routing formed by second D connecting line 44 and its connected second A line segment 9 and second B line segment 10, and the conventional second-type signal line 8 that is not disconnected on either side of light-transmitting aperture 1, thereby improving load uniformity.

[0193] Furthermore, for the second-category signal lines 8 located on both sides of the first sub-light-transmitting hole 41, the second C connecting line 43 can be electrically connected to the second-category signal lines 8 in this part of the second-category signal lines 8 close to the second sub-light-transmitting hole 42. For the second-category signal lines 8 located on both sides of the second sub-light-transmitting hole 42, the second D connecting line 44 can be electrically connected to the second-category signal lines 8 in this part of the second-category signal lines 8 close to the first sub-light-transmitting hole 41, so as to further reduce the extension length and load of the second C connecting line 43 and the second D connecting line 44.

[0194] Further, if Figure 32 As shown, Figure 32 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a first winding 45. The first winding 45 is located in the first non-display area 7 surrounding the runway hole 40. The first winding 45 is electrically connected to the second-type signal lines 8 on both sides of the first sub-light-transmitting hole 41. The first winding 45 is located between the first sub-light-transmitting hole 41 and the second C-connecting line 43. For example, at least a portion of the first winding 45 may extend in an arc along the edge of the first sub-light-transmitting hole 41.

[0195] And / or, the display panel further includes a second winding 46, the second winding 46 being located in the first non-display area 7 surrounding the runway hole 40, the second winding 46 being electrically connected to the second-type signal lines 8 on both sides of the second sub-light-transmitting hole 42, and the second winding 46 being located between the second sub-light-transmitting hole 42 and the second D-connecting line 44. Exemplarily, at least a portion of the second winding 46 may extend in an arc along an edge of the second sub-light-transmitting hole 42.

[0196] In the above-mentioned setting method, part of the second-class signal lines 8 on both sides of the runway hole 40 can also be connected by winding between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. At this time, not only can the non-effective area between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 be reasonably utilized, but the extension length of the first winding 45 and the second winding 46 is also smaller, so the load is smaller, which helps to reduce the load difference between the overall routing formed by the first winding 45 and the second A segment 9 and the second B segment 10 electrically connected thereto, the overall routing formed by the second winding 46 and the second A segment 9 and the second B segment 10 electrically connected thereto, and other conventional second-class signal lines 8, and helps to improve load uniformity.

[0197] In addition, some of the second-type signal lines 8 on both sides of the runway hole 40 are connected by winding, which can also reduce the number of second connecting lines 11 surrounding the runway hole 40 on the outside of the runway hole 40, thereby reducing the difference in extension length between the second connecting lines 11 surrounding the runway hole 40 on the outside and the second connecting lines 11 surrounding the runway hole 40 on the inside, which is beneficial to reducing the load difference between different second connecting lines 11.

[0198] In one possible implementation, Figure 33 As shown, Figure 33 This is another partial top view of a display panel provided by an embodiment of the present invention. Light-transmitting holes 1 include racetrack holes 40, which include first sub-light-transmitting holes 41 and second sub-light-transmitting holes 42 arranged along a first direction x. Furthermore, light-transmitting holes 1 other than racetrack holes 40 are located on the side of the second sub-light-transmitting holes 42 away from the first sub-light-transmitting holes 41.

[0199] At least part of the second connecting wires 11 electrically connected to the second type signal wires 8 on both sides of the first sub-light-transmitting hole 41 surrounds the runway hole 40 on the side of the first sub-light-transmitting hole 41 away from the second sub-light-transmitting hole 42, and at least part of the second connecting wires 11 electrically connected to the second type signal wires 8 on both sides of the second sub-light-transmitting hole 42 surrounds the runway hole 40 on the side of the first sub-light-transmitting hole 41 away from the second sub-light-transmitting hole 42.

[0200] With this arrangement, at least a portion of the second connecting wires 11 electrically connected to the second-type signal wires 8 on both sides of the runway hole 40 surrounds the runway hole 40 on the side of the first sub-light-transmitting hole 41 away from the second sub-light-transmitting hole 42. At this point, this portion of the second connecting wires 11 extends primarily on the side of the runway hole 40 away from the other light-transmitting holes 1, without having to extend between the runway hole 40 and the other adjacent light-transmitting holes 1. This eliminates the need to occupy space between the runway hole 40 and the other adjacent light-transmitting holes 1, thus avoiding the need for a large number of connecting wires in this area and causing signal interference. In other words, this arrangement also places fewer restrictions on the distance between the runway hole 40 and the other light-transmitting holes 1, allowing the runway hole 40 and the other light-transmitting holes 1 to be closer together, thereby increasing the flexibility of the placement of the runway hole 40 and the other light-transmitting holes 1.

[0201] In one possible implementation, Figure 34 As shown, Figure 34 This is another partial top view of a display panel provided by an embodiment of the present invention. The light-transmitting aperture 1 includes a racetrack aperture 40 and a first aperture 47. The racetrack aperture 40 includes a first sub-light-transmitting aperture 41 and a second sub-light-transmitting aperture 42 arranged along a first direction x. The aperture r1 of the first aperture 47 is smaller than the aperture r2 of the first sub-light-transmitting aperture 41, and the aperture r1 of the first aperture 47 is smaller than the aperture r3 of the second sub-light-transmitting aperture 42.

[0202] In one configuration, the first sub-light aperture 41 and the second sub-light aperture 42 of the light aperture 1 can be used to correspond to an infrared camera to implement a facial recognition function, while the first aperture 47 can be used to correspond to a camera to implement a photography function. Because the first aperture 47, the first sub-light aperture 41, and the second sub-light aperture 42 require different camera types, the apertures of the first aperture 47, the first sub-light aperture 41, and the second sub-light aperture 42 can be set to different sizes to better match the sizes of their respective cameras.

[0203] Further, see again Figure 34 The display panel further includes a first non-display area 7, which surrounds the light-transmitting hole 1 and the display area 2 surrounds the first non-display area 7. That is, the first non-display area 7 is regarded as a frame of the light-transmitting hole 1. The minimum width of the first non-display area 7 surrounding the first hole 47 is d1, and the minimum width of the first non-display area 7 surrounding the runway hole 40 is d2, where d1>d2.

[0204] By differentially designing the frame width corresponding to the runway hole 40 and the frame width corresponding to the first hole 47, the dimension L1 of the overall structure formed by the runway hole 40 and the first non-display area 7 surrounding it in the second direction y can be made consistent with the dimension L2 of the overall structure formed by the first hole 47 and the first non-display area 7 surrounding it in the second direction y. At this time, the two parts of the structure can present a more aesthetically pleasing exclamation mark shape, and the appearance design of the display panel is better.

[0205] In one possible implementation, Figure 35 As shown, Figure 35 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a sixth winding 48. One end of the sixth winding 48 is electrically connected to the first B segment 5 on one side of the first hole 47, and the other end of the sixth winding 48 is electrically connected to the first A segment 4 or the first B segment 5 on the other side of the first hole 47. The sixth winding 48 is located in the first non-display area 7 surrounding the first hole 47. At least a portion of the sixth winding 48 may extend in an arc shape along the edge of the first hole 47.

[0206] As mentioned above, the width of the frame corresponding to the first hole 47 is greater than the width of the frame corresponding to the runway hole 40. Therefore, some windings for connecting the first type of signal line 3 can be set in the frame corresponding to the first hole 47. At this time, in addition to the reasonable utilization of the frame of the first hole 47, the number of first connecting lines 6 surrounding the first hole 47 on the outside of the first hole 47 can be further reduced, thereby reducing the difference in the extension length of different first connecting lines 6, so as to reduce the load difference between different first connecting lines 6.

[0207] Furthermore, if Figure 36 As shown, Figure 36 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a shift register 21, which includes a plurality of cascaded shift units 22. The first line segment 4 on the side of the first hole 47 away from the runway hole 40 is electrically connected to a shift unit 22 in one shift register 21, while the first line segment 4 on the side of the runway hole 40 away from the first hole 47 is electrically connected to a shift unit 22 in another shift register 21.

[0208] The above-mentioned setting adopts the bilateral driving method of the shift register 21. At this time, the first-class signal lines 3 cut off on both sides of the runway hole 40 can transmit signals normally without using the first connecting wires 6 or windings to connect them, so there is no need to set connecting wires on both sides of the runway hole 40, and there is no need to set windings in the first non-display area 7 corresponding to the runway hole 40.

[0209] In one possible implementation, Figure 37 As shown, Figure 37This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a seventh winding 50, the ends of which are electrically connected to the second wire segment A 9 and the second wire segment B 10 on either side of the first hole 47. A sixth winding 48 is located in the first non-display area 7 surrounding the first hole 47.

[0210] As mentioned above, the width of the frame corresponding to the first hole 47 is greater than the width of the frame corresponding to the runway hole 40. Therefore, some seventh windings 50 for connecting the second-type signal lines 8 can be set in the frame corresponding to the first hole 47. At this time, in addition to the reasonable utilization of the frame of the first hole 47, the number of second connecting lines 11 surrounding the first hole 47 on the outside of the first hole 47 can be further reduced to reduce the load difference of different second connecting lines 11.

[0211] Further, if Figure 38 As shown, Figure 38 This is another partial top view of a display panel provided by an embodiment of the present invention, in which the display panel further includes an eighth winding 51. The eighth winding 51 includes an eighthA winding 52, the ends of which are electrically connected to the secondA segment 9 and the secondB segment 10 on either side of the first light-transmitting sub-aperture 41, respectively. The eighthA winding 52 is located in the first non-display area 7 surrounding the runway aperture 40 and extends on the side of the first light-transmitting sub-aperture 41 away from the second light-transmitting sub-aperture 42.

[0212] And / or, the eighth winding 51 also includes an eighth B winding 53, the two ends of the eighth B winding 53 are respectively electrically connected to the second A line segment 9 and the second B line segment 10 on both sides of the second sub-light-transmitting hole 42, and the eighth B winding 53 is located in the first non-display area 7 surrounding the runway hole 40, and extends on the side of the second sub-light-transmitting hole 42 away from the first sub-light-transmitting hole 41.

[0213] In the above-mentioned setting, some of the second-type signal lines 8 on both sides of the runway hole 40 can also be connected by winding within the first non-display area 7. In this case, in addition to making reasonable use of the frame of the runway hole 40, the number of second connection lines 11 surrounding the runway hole 40 on the outside of the runway hole 40 can be further reduced, thereby further reducing the load difference between different second connection lines 11.

[0214] Furthermore, since the minimum width d2 of the first non-display area 7 surrounding the runway hole 40 is smaller than the minimum width d1 of the first non-display area 7 surrounding the first hole 47, the number of eighth windings 51 can also be made smaller than the number of seventh windings 50 to avoid signal interference caused by overly dense arrangement of the windings in the first non-display area 7 surrounding the runway hole 40.

[0215] In one possible implementation, Figure 39 As shown, Figure 39This is another partial top view of a display panel provided by an embodiment of the present invention. The light-transmitting aperture 1 includes a racetrack aperture 40, which includes first sub-light-transmitting apertures 41 and second sub-light-transmitting apertures 42 arranged along a first direction x. The display panel also includes a first non-display area 7, which surrounds the light-transmitting aperture 1 and the display area 2 surrounds the first non-display area 7. The first non-display area 7 surrounding the racetrack aperture 40 includes a first sub-non-display area 54, which is located between the first sub-light-transmitting aperture 41 and the second sub-light-transmitting aperture 42. A sensing element 55 is correspondingly disposed in the first sub-non-display area 54.

[0216] In this embodiment of the present invention, the sensing element 55 is configured to work in conjunction with cameras located at the first and second sub-light-transmitting apertures 41, 42 to achieve specific functions. For example, infrared cameras are located at the first and second sub-light-transmitting apertures 41, 42, and a distance sensor, ambient light sensor, and the like are located at the first sub-non-display area 54. The infrared cameras and the sensing element 55 cooperate to perform facial recognition, thereby improving facial recognition accuracy and optimizing the performance of the display panel.

[0217] In one possible setup, such as Figure 40 As shown, Figure 40 This is another partial top view of the display panel provided in an embodiment of the present invention. The display panel also includes a pixel circuit 20 and a first virtual pixel circuit 56. The first virtual pixel circuit 56 is located in the first non-display area 7, and the pixel circuit 20 and at least part of the first virtual pixel circuit 56 are respectively electrically connected to the first type signal line 3.

[0218] It should be noted that the first dummy pixel circuit 56 is used to ensure uniformity of pattern density and optimize etching effects. In one configuration, the portion of the first-type signal line 3 electrically connected to the pixel circuit 20 and the portion electrically connected to the first dummy pixel circuit 56 can be electrically connected to each other, so as to utilize the first dummy pixel circuit 56 to further improve load uniformity between different first-type signal lines 3. Alternatively, in another configuration, the portion of the first-type signal line 3 electrically connected to the pixel circuit 20 and the portion electrically connected to the first dummy pixel circuit 56 can also be disconnected and electrically insulated from each other.

[0219] Among them, the number of first-class signal lines 3 electrically connected to the first virtual pixel circuit 56 in the first sub-non-display area 54 is less than the number of first-class signal lines 3 electrically connected to the pixel circuit 20, so as to reduce the number of first-class signal lines 3 set in the first sub-non-display area 54, improve the transmittance of the first sub-non-display area 54, and allow more external ambient light to pass through the first sub-non-display area 54 and enter the sensing element 55, thereby improving the accuracy of facial recognition.

[0220] It should be noted that, in an embodiment of the present invention, the number of first-type signal lines 3 connected to the first virtual pixel circuit 56 in the first sub-non-display area 54 may also be 0, that is, the first virtual pixel circuit 56 in the first sub-non-display area 54 is not electrically connected to the first-type signal line 3. At this time, the transmittance of the first sub-non-display area 54 can be improved to a greater extent.

[0221] In addition, it should be noted that the first virtual pixel circuit 56 is not used to drive the light-emitting element D to emit light. Therefore, even if the number of first-type signal lines 3 connected to the first virtual pixel circuit 56 in the first sub-non-display area 54 is reduced, it will not affect the normal function of the display panel.

[0222] Furthermore, if Figure 41 As shown, Figure 41 This is another partial top view of a display panel provided by an embodiment of the present invention. The first non-display area 7 surrounding the runway hole 40 also includes a second sub-non-display area 57. The display panel also includes a third winding 58. One end of the third winding 58 is electrically connected to the first line segment 4 or the first line segment 5 on one side of the runway hole 40, and the other end of the third winding 58 is electrically connected to the first line segment 4 or the first line segment 5 on the other side of the runway hole 40. The third winding 58 is located in the second sub-non-display area 57, and at least a portion of the third winding 58 is multiplexed with the first type signal line 3 electrically connected to the first virtual pixel circuit 56 in the second sub-non-display area 57.

[0223] With such an arrangement, at least a portion of the third winding 58 can be reused with the first type of signal line 3 electrically connected to the first virtual pixel circuit 56, which can reduce the number of wirings arranged in the first non-display area 7. In addition, based on the existence of the light-transmitting hole 1, a portion of the first type of signal line 3 will be truncated and arranged on the upper and lower sides of the light-transmitting hole 1. Therefore, compared with the conventional first type of signal line 3 that does not need to be truncated on the upper and lower sides of the light-transmitting hole 1, the number of pixel circuits 20 electrically connected to the truncated first type of signal line 3 is smaller, and the corresponding load is also smaller. In an embodiment of the present invention, by reusing at least a portion of the third winding 58 with the first type of signal line 3 electrically connected to the first virtual pixel circuit 56, the number of circuits connected to the overall routing formed by the first A line segment 4, the third winding 58 and the first B line segment 5 can be made consistent with the number of circuits connected to the conventional first type of signal line 3, which helps to improve the load consistency between different signal lines.

[0224] In one possible setup, such as Figure 42 As shown, Figure 42This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a first dummy pixel circuit 56, which is located in the first non-display area 7. The first non-display area 7 also includes a second sub-non-display area 57. The first dummy pixel circuit 56 in the first non-display area 7 is only located in the second sub-non-display area 57.

[0225] In the above-mentioned setting method, not only can the first virtual pixel circuit 56 be used to improve etching uniformity or load uniformity, but also, by setting the first virtual pixel circuit 56 in the first non-display area 7 only in the second sub-non-display area 57, it is also possible to avoid the metal wiring forming the first virtual pixel circuit 56 from blocking the external ambient light, thereby greatly improving the transmittance of the first sub-non-display area 54, and allowing more external ambient light to pass through the first sub-non-display area 54 and enter the sensing element 55.

[0226] In one possible implementation, Figure 43 As shown, Figure 43 This is another partial top view of a display panel provided by an embodiment of the present invention. The light-transmitting aperture 1 includes a racetrack aperture 40 and a first aperture 47. The racetrack aperture 40 includes a first sub-light-transmitting aperture 41 and a second sub-light-transmitting aperture 42 arranged along a first direction x. The distance between the first sub-light-transmitting aperture 41 and the second sub-light-transmitting aperture 42 is h1, and the distance between the second sub-light-transmitting aperture 42 and the first aperture 47 is h2, where h1>h2.

[0227] As mentioned above, a sensing element 55 can be correspondingly arranged between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. Therefore, when designing the distance between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 and the distance between the second sub-light-transmitting hole 42 and the first hole 47, the distance between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 can be designed to be larger to accommodate more sensing elements 55, thereby further improving the accuracy of facial recognition.

[0228] In one possible implementation, Figure 44 As shown, Figure 44 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel includes a first non-display area 7 . The first non-display area 7 surrounds the light-transmitting hole 1 , and the display area 2 surrounds the first non-display area 7 .

[0229] The display panel includes a first virtual straight line 62 and a second virtual straight line 63, which extend along the second direction y at least between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42, and the first virtual straight line 62 intersects with the edge of the first sub-light-transmitting hole 41, and the second virtual straight line 63 intersects with the edge of the second sub-light-transmitting hole 42.

[0230] The display area 2 includes a third sub-display area 64 and a fourth sub-display area 65. The third sub-display area 64 and the fourth sub-display area 65 are respectively located on both sides of the runway hole 40 in the second direction y, and the two opposite edges of the third sub-display area 64 in the first direction x coincide with the first virtual straight line 62 and the second virtual straight line 63 respectively. The two opposite edges of the fourth sub-display area 65 in the first direction x coincide with the first virtual straight line 62 and the second virtual straight line 63 respectively.

[0231] The display panel also includes a ninth winding 66, one end of which is electrically connected to the second line segment A 9 in the third sub-display area 64, and the other end of the ninth winding 66 is electrically connected to the second line segment B 10 in the fourth sub-display area 65. The ninth winding 66 extends along the second direction y in the first non-display area 7 surrounding the runway hole 40.

[0232] Since the distance between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 is relatively large, for the second-type signal line 8 located in the third sub-display area 64 and the fourth sub-display area 65, the ninth winding 66 extending along the second direction y in the first non-display area 7 can be directly used for electrical connection. This not only can reasonably utilize this part of the non-effective area between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42, but also can make the ninth winding 66 have a smaller extension length, so that the load of the overall routing composed of the ninth winding 66 and the second A line segment 9 and the second B line segment 10 connected thereto tends to be consistent with the load of the conventional second-type signal line 8.

[0233] Further, if Figure 45 As shown, Figure 45 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a tenth winding 67, which is located in the first non-display area 7 surrounding the runway hole 40. The tenth winding 67 is electrically connected to the second-type signal lines 8 on both sides of the first sub-light-transmitting hole 41. The tenth winding 67 is located between the first sub-light-transmitting hole 41 and the ninth winding 66. At least a portion of the tenth winding 67 may extend in an arc along the edge of the first sub-light-transmitting hole 41.

[0234] And / or, the display panel further includes an eleventh winding line 68, which is located in the first non-display area 7 surrounding the runway hole 40. The eleventh winding line 68 is electrically connected to the second-type signal lines 8 on both sides of the second sub-light-transmitting hole 42, and the second winding line 46 is located between the second sub-light-transmitting hole 42 and the ninth winding line 66. At least a portion of the eleventh winding line 68 may extend in an arc along the edge of the second sub-light-transmitting hole 42.

[0235] In the above-mentioned setting method, part of the second-class signal lines 8 on both sides of the runway hole 40 can also be connected by winding between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. At this time, not only can the wider space between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 be reasonably utilized, but the extension length of the tenth winding 67 and the eleventh winding 68 will be smaller, so the load is smaller, which helps to reduce the load difference between the overall routing composed of the tenth winding 67 and the second A segment 9 and the second B segment 10 electrically connected to it, the overall routing composed of the eleventh winding 68 and the second A segment 9 and the second B segment 10 electrically connected to it, and other conventional second-class signal lines 8.

[0236] In addition, some of the second-type signal lines 8 on both sides of the runway hole 40 are connected by winding, which can also reduce the number of second connecting lines 11 surrounding the runway hole 40 on the outside of the runway hole 40, thereby reducing the difference in extension length between the second connecting lines 11 surrounding the runway hole 40 on the outside and the second connecting lines 11 surrounding the runway hole 40 on the inside, which is conducive to reducing the load difference between different second connecting lines 11.

[0237] Furthermore, if Figure 46 As shown, Figure 46 This is another partial top view of the display panel provided by an embodiment of the present invention. The second connecting line 11 includes at least one second C connecting line 43. The second C connecting line 43 is electrically connected to the second type of signal line 8 on both sides of the first sub-light-transmitting hole 41, and the second C connecting line 43 is partially located between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42.

[0238] And / or, the second connecting line 11 includes at least one second D connecting line 44, the second D connecting line 44 is electrically connected to the second type of signal line 8 on both sides of the second sub-light-transmitting hole 42, and the second D connecting line 44 is partially located between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42.

[0239] Because the distance between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 is relatively large, a second C-connecting wire 43 and a second D-connecting wire 44 can also be provided extending between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42. Compared to the second connecting wire 11 that surrounds the runway hole 40 outside, the second C-connecting wire 43 and the second D-connecting wire 44 extending between the first sub-light-transmitting hole 41 and the second sub-light-transmitting hole 42 have a correspondingly shorter extension length, thereby reducing their load. Furthermore, this arrangement can reduce the number of second connecting wires 11 that surround the runway hole 40 outside, thereby reducing the load differences between different second connecting wires 11.

[0240] In one possible implementation, Figure 47 As shown, Figure 47This is another partial top view of the display panel provided by an embodiment of the present invention. The display panel further includes a first non-display area 7 surrounding the light-transmitting hole 1 , and the display area 2 surrounds the first non-display area 7 .

[0241] The display panel further includes a fourth winding 69 located in the first non-display area 7. One end of the fourth winding 69 is electrically connected to the first wire segment B 5, and the other end of the fourth winding 69 is electrically connected to the first wire segment A 4 or another first wire segment B 5. Furthermore, / or, the display panel further includes a fifth winding 70 located in the first non-display area 7. The fifth winding 70 is electrically connected to the second wire segment A 9 and the second wire segment B 10, respectively.

[0242] In the above-mentioned setting, the first type signal line 3 that is cut off on both sides of the light-transmitting hole 1 and / or the second type signal line 8 that is cut off on both sides of the light-transmitting hole 1 can also be electrically connected by winding in the first non-display area 7. This type of winding only needs to be wound within the frame around the light-transmitting hole 1, so its extension length is small and the load is also small. At this time, the load difference between the overall routing formed by the fourth winding 69 and the first A line segment 4 and the first B line segment 5 electrically connected to it and the conventional first type signal line 3 can be reduced, and the load difference between the overall routing formed by the fifth winding 70 and the second A line segment 9 and the second B line segment 10 electrically connected to it and the conventional second type signal line 8 can be reduced.

[0243] Moreover, this setting method can also reduce the number of first connecting lines 6 and second connecting lines 11 required to be set, avoid excessive differences in the extension lengths of the first connecting lines 6 of the inner and outer circles, and avoid excessive differences in the extension lengths of the second connecting lines 11 of the inner and outer circles, thereby reducing the load differences between different first connecting lines 6 and reducing the load differences between different second connecting lines 11.

[0244] In one possible embodiment, combining Figure 3 ,like Figures 48 to 52 As shown, Figure 48 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 49 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 50 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 51 This is another partial top view of a display panel provided by an embodiment of the present invention. Figure 52 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel further includes a second non-display area 71. The second non-display area 71 is located on one side of the display area 2 in the second direction y, and the light-transmitting hole 1 is adjacent to the second non-display area 71. A portion of the first connecting wires 6 is also located in the second non-display area 71, and / or a portion of the second connecting wires 11 is also located in the second non-display area 71.

[0245] Among them, the above-mentioned second non-display area 71 can be understood as the upper frame of the display panel. Under normal circumstances, the light-transmitting hole 1 in the display panel will generally be closer to the upper frame of the display panel. At this time, when setting the first connecting line 6 and the second connecting line 11, when the first connecting line 6 and the second connecting line 11 surround the light-transmitting hole 1 on the outside of the light-transmitting hole 1, if the number of the first connecting line 6 and the second connecting line 11 is large, the laterally extending parts of some of the first connecting lines 6 and some of the second connecting lines 11 can be located in the second non-display area 71, thereby avoiding the laterally extending parts of the connecting lines from being arranged too densely in the upper display area 2, thereby avoiding signal interference and the like.

[0246] In one possible implementation, Figure 53 As shown, Figure 53 This is another partial top view of the display panel provided in an embodiment of the present invention. The display panel also includes a second virtual pixel circuit 72 located in the second non-display area 71, part of the second virtual pixel circuit 72 is electrically connected to the first connection line 6, and / or part of the second virtual pixel circuit 72 is electrically connected to the second connection line 11.

[0247] Taking the first-class signal lines 3 as an example, due to the presence of the light-transmitting hole 1, some of the first-class signal lines 3 are truncated and arranged on the left and right sides of the light-transmitting hole 1. Therefore, compared with conventional first-class signal lines 3 that do not need to be truncated on the upper and lower sides of the light-transmitting hole 1, the number of pixel circuits 20 electrically connected to the truncated first-class signal lines 3 is smaller, and the corresponding load is smaller. In an embodiment of the present invention, when some of the first connecting lines 6 extend within the second non-display area 71, a second dummy pixel circuit 72 connected thereto can be further provided in the second non-display area 71. This ensures that the number of circuits connected to the first-class signal lines 3 connected to the first-class signal lines 3 is consistent with the number of circuits connected to the conventional first-class signal lines 3, thereby effectively improving the load consistency between different signal lines.

[0248] In one possible implementation, Figure 54 As shown, Figure 54 This is another partial top view of the display panel provided by an embodiment of the present invention. The display panel also includes a second-type signal line 8. The second-type signal line 8 is located in the display area 2 and extends along the second direction y. Part of the second-type signal line 8 includes a second A line segment 9 and a second B line segment 10. The second A line segment 9 and the second B line segment 10 are respectively located on both sides of the light-transmitting hole 1 in the second direction y, and the second direction y intersects with the first direction x.

[0249] Combine Figure 3 The display panel further includes a second non-display area 71 and a third non-display area 73 arranged opposite to each other in the second direction y of the display area 2, and the second non-display area 71 is close to the second line segment A 9.

[0250] The display panel further includes a third dummy pixel circuit 74 . The third dummy pixel circuit 74 is located in the second non-display area 71 and is electrically connected to the second A line segment 9 .

[0251] Due to the presence of the light-transmitting hole 1, some of the second-class signal lines 8 are cut off and set on the upper and lower sides of the light-transmitting hole 1. Therefore, compared with the conventional second-class signal lines 8 that do not need to be cut off on the left and right sides of the light-transmitting hole 1, the number of pixel circuits 20 electrically connected to the cut-off second-class signal lines 8 is smaller, and the corresponding load is smaller. In an embodiment of the present invention, by providing a third virtual pixel circuit 74 connected to the second A line segment 9 in the second non-display area 71, the number of circuits connected to the overall routing formed by the second A line segment 9, the second connecting line 11, and the second B line segment 10 can be made consistent with the number of circuits connected to the conventional second-class signal lines 8, thereby effectively improving the load consistency between different second-class signal lines 8.

[0252] In one possible implementation, Figure 55 As shown, Figure 55 This is another partial top view of the display panel provided in an embodiment of the present invention. In the direction perpendicular to the plane of the display panel, the portion of the first connecting line 6 and / or the second connecting line 11 extending along the first direction x overlaps with the first type signal line 3, and the portion of the first connecting line 6 and / or the second connecting line 11 extending along the second direction y overlaps with the second type signal line 8.

[0253] When the first connecting line 6 overlaps with the existing first-type signal lines 3 and second-type signal lines 8 in the display panel, ambient light is incident on the location of the first connecting line 6, which can reduce the additional impact of the first connecting line 6 on the reflection of the ambient light, thereby reducing the impact of the first connecting line 6 on the reflection uniformity of the display panel. Similarly, when the second connecting line 11 overlaps with the existing first-type signal lines 3 and second-type signal lines 8 in the display panel, the impact of the second connecting line 11 on the reflection uniformity of the display panel can also be reduced.

[0254] In one possible implementation, Figure 56 As shown, Figure 56 for Figure 55 In a cross-sectional view along the A1-A2 direction, the first connecting line 6 and the first type signal line 3 and the second type signal line 8 are arranged in different layers, and the second connecting line 11 and the first type signal line 3 and the second type signal line 8 are arranged in different layers.

[0255] Illustratively, in one configuration, the first connecting line 6 and the second connecting line 11 are arranged in the same layer, and the film layer in which they are located is located on the side of the first-type signal line 3 and the second-type signal line 8 facing away from the substrate 75. In addition, a first insulating layer 76 is provided between the first-type signal line 3 and the second-type signal line 8, and a second insulating layer 77 is provided between the second-type signal line 8 and the first connecting line 6 and the second connecting line 11. Alternatively, in another configuration, the portion of the first connecting line 6 extending along the first direction x and the portion of the second connecting line 11 extending along the first direction x are arranged in the same layer and are located on the side of the first-type signal line 3 and the second-type signal line 8 facing away from the substrate 75, the portion of the second connecting line 6 extending along the second direction y and the portion of the second connecting line 11 extending along the second direction y are arranged in the same layer and are located on the side of the first-type signal line 3 and the second-type signal line 8 facing away from the substrate 75, and the portion of the first connecting line 6 extending along the first direction x and the portion of the first connecting line 6 extending along the second direction y may be in different layers.

[0256] Generally, the first-category signal lines 3 and the second-category signal lines 8 in a display panel are arranged relatively closely, especially in a high-resolution display panel, where the first-category signal lines 3 and the second-category signal lines 8 are arranged even closer to each other. If the first connecting lines 6 or the second signal lines are provided on the same layer as the first-category signal lines 3 or the second-category signal lines 8, either the spacing between the first-category signal lines 3 or the spacing between the second-category signal lines 8 is increased to avoid a short circuit between the signal lines, but this requires readjusting the pattern of the mask; or, the spacing between the first-category signal lines 3 or the spacing between the second-category signal lines 8 is not adjusted, and the first connecting lines 6 or the second signal lines are directly added between the first-category signal lines 3 or the second-category signal lines 8, but this is likely to cause a short circuit between the signal lines.

[0257] In this regard, the embodiment of the present invention arranges the first connecting line 6 and the second connecting line 11 in different layers from the first type signal line 3 and the second type signal line 8 respectively. The first connecting line 6 and the second connecting line 11 do not need to occupy the film layer space of the first type signal line 3 and the second type signal line 8, thereby reducing the risk of short circuit and eliminating the need to adjust the layout design of the first type signal line 3 and the second type signal line 8. For example, there is no need to increase the spacing between these lines to accommodate the first connecting line 6 or the second connecting line 11, and therefore there is no need to change the pattern of the original mask plate.

[0258] In one possible implementation, Figure 57 As shown, Figure 57This is another partial top view of a display panel provided by an embodiment of the present invention. The first connecting lines 6 include first A connecting lines 78 and first B connecting lines 79. The length of first A connecting lines 78 is smaller than the length of first B connecting lines 79, and the line width of first A connecting lines 78 is smaller than the line width of first B connecting lines 79. This allows the loads of first A connecting lines 78 and first B connecting lines 79 to be consistent, thereby improving the load consistency of different first connecting lines 6.

[0259] In one possible implementation, Figure 58 As shown, Figure 58 This is another partial top view of a display panel provided by an embodiment of the present invention. The display area 2 includes a first sub-display area 80 and a second sub-display area 81. The first connecting line 6 is located in the first sub-display area 80. The display panel also includes a dummy trace 82 located in the second sub-display area 81. In one configuration, the dummy trace 82 can be provided on the same layer as the first connecting line 6.

[0260] After the first connection line 6 is provided in the first sub-display area 80, the first connection line 6 may have an additional impact on the reflectivity of the first sub-display area 80. To address this issue, the embodiment of the present invention adds a dummy line 82 in the second sub-display area 81 where the first connection line 6 is not provided. The reflection of ambient light by the dummy line 82 can be utilized to improve the uniformity of the reflection of external ambient light in the first sub-display area 80 and the second sub-display area 81.

[0261] Furthermore, dummy trace 82 receives a fixed voltage and can act as a shielding metal to prevent interference between different signal lines. Furthermore, when dummy trace 82 receives a fixed voltage, it can be electrically connected to the reset signal line Vref and the power signal line PVDD in display area 2, which are used to transmit the fixed voltage. This reduces the load on the reset signal line Vref and the power signal line PVDD, thereby reducing the voltage drop of the reset signal and the power signal during transmission.

[0262] Further, combined with Figure 16 ,like Figure 59 As shown, Figure 59 This is a top view of the film layer structure of the display panel provided in an embodiment of the present invention. The display panel also includes a pixel circuit 20 located in the display area 2. The pixel circuit 20 includes a driving transistor M0. The gate of the driving transistor M0 is electrically connected to the first node N1. In the direction perpendicular to the plane of the display panel, the virtual trace 82 overlaps with the first node N1 of part of the pixel circuit 20.

[0263] During the operation of the pixel circuit 20, the stability of the gate potential of the driving transistor M0 largely determines the reliability of the operating state of the driving transistor M0. In an embodiment of the present invention, when the dummy trace 82 receives a fixed voltage, by overlapping the dummy trace 82 with the first node N1 of a portion of the pixel circuit 20, the dummy trace 82 can also shield the interference of other structures on the gate potential of the driving transistor M0, such as shielding the interference of the voltage jump on the data line Data on the gate potential of the driving transistor M0, thereby improving the stability of the gate potential of the driving transistor M0 and thereby improving the reliability of the driving current converted by it.

[0264] In one possible implementation, Figure 60 As shown, Figure 60 This is a schematic diagram of the spacing of the connecting lines provided in an embodiment of the present invention. The display panel further includes a pixel circuit 20 located in the display area 2. The size of the pixel circuit 20 in the first direction x is A, and the size of the pixel circuit 20 in the second direction y is B.

[0265] The distance between at least part of the first connecting line 6 and the first connecting line 6 or the second connecting line 11 adjacent to it in the first direction x is A, and the distance between at least part of the first connecting line 6 and the first connecting line 6 or the second connecting line 11 adjacent to it in the second direction y is B; the distance between at least part of the second connecting line 11 and the first connecting line 6 or the second connecting line 11 adjacent to it in the first direction x is A, and the distance between at least part of the second connecting line 11 and the first connecting line 6 or the second connecting line 11 adjacent to it in the second direction y is B.

[0266] With this arrangement, the first connection lines 6 and the second connection lines 11 are evenly distributed at equal intervals in the display area 2, which makes the arrangement more regular and avoids the first connection lines 6 and the second connection lines 11 being concentrated in a certain area and causing a large coupling to the original signal lines in the display area 2.

[0267] In one possible implementation, Figure 61 As shown, Figure 61 This is another partial top view of a display panel provided by an embodiment of the present invention. The display panel includes at least three light-transmitting holes 1 .

[0268] The first connecting line 6 includes a first line segment 83 extending along a first direction x and a plurality of second line segments 84 extending along a second direction y, which intersects the first direction x. Each first line segment A 4 and each first line segment B 5 is electrically connected to the first line segment 83 via a second line segment 84 .

[0269] At this point, the first B line segment 5 between each two adjacent light-transmitting holes 1 is connected to the first A line segments 4 on both sides, forming a continuous signal transmission path, ensuring signal transmission on each first B line segment 5. Furthermore, with this configuration, the shift register 21 can adopt either bilateral or unilateral drive, providing greater flexibility in driving methods.

[0270] In one possible embodiment, combining Figure 16 and Figure 27 The display panel further includes pixel circuits 20 located in the display area 2.
