In practical applications, the shift register in the gate drive circuit may also be divided into three register groups, four register groups, or more register groups, which is not limited here.

[0123] In practical applications, the frame start signal terminal is electrically connected to the shift register's input signal terminal IP via a signal lead-in line. However, currently, the signal lead-in lines corresponding to the same frame start signal terminal are arranged in the same area, and no other signal lines are arranged between the signal lead-in lines corresponding to the same frame start signal terminal, which is not conducive to the wiring of the signal lead-in lines.

[0124] In the disclosed embodiment, multiple signal lead-in lines are also provided in the non-display area. These multiple signal lead-in lines are divided into multiple line groups, with each register group electrically connected to one line group. Furthermore, signal lead-in lines from other line groups are provided between two signal lead-in lines in the same line group. For example, these multiple signal lead-in lines can be signal lines that electrically connect the frame start signal terminal to the input signal terminal IP of the shift register. Alternatively, these multiple signal lead-in lines can be clock signal lines or signal lines with other functions.

[0125] For example, when these multiple signal introduction lines are signal lines that electrically connect the frame start signal terminal to the input signal terminal IP of the shift register, in the embodiment of the present disclosure, Figure 2 、 Figure 3a 、 Figure 5a as well as Figure 5b As shown, the plurality of signal lead-in lines can be divided into two line groups: wherein the first line group of the two line groups includes signal lead-in lines 110-1, 110-2, and 110-3, and the first line group is connected to the frame start signal terminal STV_A of the first register group X1. wherein the signal lead-in line 110-1 is connected between the frame start signal terminal STV_A and the input signal terminal IP of the first stage shift register SR(1), the signal lead-in line 110-2 is connected between the frame start signal terminal STV_A and the input signal terminal IP of the third stage shift register SR(3), and the signal lead-in line 110-3 is connected between the frame start signal terminal STV_A and the input signal terminal IP of the fifth stage shift register SR(5).

[0126] And, combined with Figure 2 、 Figure 3b 、 Figure 5a 、 Figure 5b as well as Figure 6 As shown, the second line group of the two line groups includes signal lead-in lines 120-1, 120-2, and 120-3. Furthermore, the second line group is connected to the frame start signal terminal STV_B of the second register group X2. Among them, the signal lead-in line 120-1 is connected between the frame start signal terminal STV_B and the input signal terminal IP of the second-stage shift register SR(2), the signal lead-in line 120-2 is connected between the frame start signal terminal STV_B and the input signal terminal IP of the fourth-stage shift register SR(4), and the signal lead-in line 120-3 is connected between the frame start signal terminal STV_B and the input signal terminal IP of the sixth-stage shift register SR(6).

[0127] And, combined Figure 5a as well as Figure 5b As shown, the signal lead-in lines in the first line group and the signal lead-in lines in the second line group are arranged alternately. For example, signal lead-in line 120-3, signal lead-in line 110-3, signal lead-in line 120-2, signal lead-in line 110-2, signal lead-in line 120-1, and signal lead-in line 110-1 are arranged in the direction indicated by arrow F1. This optimizes wiring space.

[0128] In the disclosed embodiment, a sub-pixel of a display panel includes a transistor, and the transistor includes a gate, an active layer, and a source / drain electrode. The gate is provided on the same layer and material as the gate line, and the source / drain is provided on the same layer and material as the data line. The active layer may be located between the layer where the gate line resides and the layer where the data line resides. Furthermore, a gate insulating layer is provided between the layer where the gate line resides and the layer where the active layer resides, and an interlayer insulating layer (e.g., PVX) is provided between the layer where the active layer resides and the layer where the data line resides.

[0129] In the disclosed embodiment, the signal lead-in lines can be provided in the same layer and material as the gate lines. This allows the gate lines and the signal lead-in lines to be formed simultaneously through a single patterning process simply by changing the original mask pattern when forming the gate line pattern. This eliminates the need for a separate process for preparing the signal lead-in lines, simplifying the manufacturing process, saving production costs, and improving production efficiency.

[0130] In the embodiment of the present disclosure, the display panel may further include: a plurality of signal introduction parts and a plurality of bridge parts; wherein the signal introduction parts and the signal introduction lines are located in the same layer; and one of the plurality of line groups is electrically connected to the signal introduction parts in the plurality of signal introduction parts. Moreover, one of the plurality of line groups is directly electrically connected to the corresponding signal introduction part, and the remaining line groups are electrically connected to the corresponding signal introduction parts through the bridge parts. For example, when these plurality of signal introduction lines are signal lines that electrically connect the frame start signal terminal to the input signal terminal IP of the shift register, in the embodiment of the present disclosure, the plurality of signal introduction parts include a first signal introduction part 210 and a second signal introduction part 220; in combination Figure 2 、 Figure 3a as well as Figures 5a to 6 As shown, the first signal lead-in section 210 is an integral structure formed of the same film material, and the signal lead-in lines 110-1, 110-2, and 110-3 in the first line group can be directly electrically connected to the first signal lead-in section 210. In other words, the signal lead-in lines 110-1, 110-2, and 110-3 in the first line group and the first signal lead-in section 210 are an integral structure formed of the same film material. The signal lead-in lines 120-1, 120-2, and 120-3 in the second line group can be electrically connected to the second signal lead-in section 220 via the bridge section 300. In other words, there is a gap between the signal lead-in lines 120-1, 120-2, and 120-3 in the second line group and the second signal lead-in section 220.

[0131] Specifically, the first ends of the signal introduction lines 110-1, 110-2, and 110-3 in the first line group can be directly electrically connected to the first signal introduction unit 210, and the second ends of the signal introduction lines 110-1, 110-2, and 110-3 in the first line group can be respectively electrically connected to the input signal terminal IP of the shift register in the first register group. In this way, the signal stv_a input by the first signal introduction unit 210 can be directly input to the input signal terminal IP of the second-stage shift register SR(1) through the signal introduction line 110-1. Furthermore, the signal stv_a input by the first signal introduction unit 210 can be directly input to the input signal terminal IP of the third-stage shift register SR(3) through the signal introduction line 110-2. Furthermore, the signal stv_a input by the first signal introduction unit 210 can be directly input to the input signal terminal IP of the fifth-stage shift register SR(5) through the signal introduction line 110-3.

[0132] The first ends of the signal introduction lines 120-1, 120-2, and 120-3 in the second line group can be electrically connected to the second signal introduction part 220 via the bridge portion 300. The second ends of the signal introduction lines 120-1, 120-2, and 120-3 in the second line group can be electrically connected to the input signal terminal IP of the shift register in the second register group. In this way, the signal stv_b input from the second signal introduction part 220 can be input to the input signal terminal IP of the second-stage shift register SR(2) in sequence through the bridge portion 300 and the signal introduction line 120-1 in a bridging manner. In addition, the signal stv_b input from the second signal introduction part 220 can be input to the input signal terminal IP of the fourth-stage shift register SR(4) in sequence through the bridge portion 300 and the signal introduction line 120-2 in a bridging manner. Furthermore, the signal stv_b inputted from the second signal introducing portion 220 is sequentially inputted into the input signal terminal IP of the sixth stage shift register SR(6) through the bridge portion 300 and the signal introducing line 120-3 in a bridge manner.

[0133] In the disclosed embodiment, the bridge portion and the signal introduction portion are located in different layers. For example, the bridge portion can be provided in the same layer and material as the data line. This allows the data line pattern and the bridge portion pattern to be formed simultaneously in a single patterning process, simply by changing the original mask pattern when forming the data line pattern. This eliminates the need for a separate process for preparing the bridge portion, simplifying the manufacturing process, reducing production costs, and improving production efficiency.

[0134] In the embodiment of the present disclosure, Figures 5a to 6As shown, the bridge portion may include a first bridge portion 310, a second bridge portion 320, and a third bridge portion 330 connected between the first bridge portion 310 and the second bridge portion 320. Furthermore, the display panel may further include a first bridge connection portion 410 and a second bridge connection portion 420; wherein the first bridge connection portion 410 is located on a different layer from the bridge portion and the signal introduction portion, and the second bridge connection portion 420 is located on the same layer as the first bridge connection portion 410. For example, when the display panel is a liquid crystal display panel, the first bridge connection portion 410 and the second bridge connection portion 420 may be provided on the same layer and made of the same material as the pixel electrode.

[0135] In the embodiment of the present disclosure, Figures 5a to 6 As shown, the first end of the first bridging connection portion 410 is electrically connected to the first bridging portion 310 via a first transfer via GZ1, and the second end of the first bridging connection portion 410 is electrically connected to the second signal introduction portion 220 via a second transfer via GZ2. Furthermore, the first end of the second bridging connection portion 420 is electrically connected to the second bridging portion 320 via a third transfer via GZ3, and the second end of the second bridging connection portion 420 is electrically connected to the signal introduction line in the second line group via a fourth transfer via GZ4.

[0136] Exemplarily, the first transfer via GZ1 penetrates the interlayer insulating layer, and the second transfer via GZ2 penetrates the gate insulating layer and the interlayer insulating layer.

[0137] For example, the total number of first transfer vias GZ1 and the total number of second transfer vias GZ2 can be the same. For example, the total number of first transfer vias GZ1 and the total number of second transfer vias GZ2 can both be 12, 10, 8, or another number. Alternatively, the total number of first transfer vias GZ1 and the total number of second transfer vias GZ2 can also be different. Of course, in actual applications, the total number of first transfer vias GZ1 and the total number of second transfer vias GZ2 can be designed and determined based on the needs of the actual application and are not limited here.

[0138] In the embodiment of the present disclosure, Figures 5a to 6As shown, the third bridge portion 330 may include multiple third sub-bridge portions spaced apart from each other, and the second bridge portion 320 may include multiple second sub-bridge portions. Each third sub-bridge portion corresponds to one signal lead-in line, and each second sub-bridge portion corresponds to one signal lead-in line. For example, if the second line group includes signal lead-in lines 120-1, 120-2, and 120-3, then signal lead-in line 120-1 corresponds to the third sub-bridge portion 331 and the second sub-bridge portion 321, and signal lead-in line 120-1 is electrically connected to the first bridge portion 310 via the second sub-bridge portion 321 and the third sub-bridge portion 331, respectively. Furthermore, signal lead-in line 120-2 corresponds to the third sub-bridge portion 332 and the second sub-bridge portion 322, and signal lead-in line 120-2 is electrically connected to the first bridge portion 310 via the second sub-bridge portion 322 and the third sub-bridge portion 332, respectively. Signal lead-in line 120-3 corresponds to third sub-bridge portion 333 and second sub-bridge portion 323, and is electrically connected to first bridge portion 310 via second sub-bridge portion 323 and third sub-bridge portion 333, thereby forming a signal transmission path. Furthermore, by spacing the multiple third sub-bridge portions apart, the overlap area between the third sub-bridge portions and the signal lead-in lines in the first line group can be reduced, thereby reducing signal interference.

[0139] In the embodiment of the present disclosure, the shape of the third sub-bridge portion may be a non-linear shape, for example, Figure 5c As shown, the shape of the third sub-bridge portion (331, 332, 333) can be a bending line shape. Furthermore, the third sub-bridge portion (331, 332, 333) can be a bending line shape composed of three straight line segments and can have two bending angles, which can be obtuse angles. Alternatively, the shape of the third sub-bridge portion can also be a curved shape. Furthermore, the third sub-bridge portion can be composed of an arc-shaped curve. Of course, in actual applications, the shape of the third sub-bridge portion can be determined according to the needs of the actual application and is not limited here.

[0140] In the embodiment of the present disclosure, Figure 5a 、 Figure 5c as well as Figure 6 As shown, multiple second sub-bridges can be spaced apart. For example, gaps are formed between the second sub-bridges 321, 322, and 323, and the orthographic projections of the multiple second sub-bridges on the substrate do not overlap with the orthographic projections of the signal lead-in wires in the first line group. This reduces the overlap between the second sub-bridges and the signal lead-in wires in the first line group, thereby reducing signal interference.

[0141] In the embodiment of the present disclosure, Figures 5a to 6As shown, the second bridge connection portion 420 may include a plurality of second sub-bridge connection portions spaced apart from each other; wherein one second sub-bridge connection portion is electrically connected to one second sub-bridge connection portion via a third transfer via GZ3. For example, the second bridge connection portion 420 includes three second sub-bridge connection portions spaced apart from each other: 421, 422, and 423. wherein the second sub-bridge connection portion 421 is electrically connected to the second sub-bridge connection portion 321 via a third transfer via GZ3, and the second sub-bridge connection portion 421 is electrically connected to the signal lead-in line 120-1 via a fourth transfer via GZ4. In this way, the signal stv_b input from the second signal lead-in portion 220 can be sequentially input to the input signal terminal IP of the second-stage shift register SR(2) via the first bridge connection portion 410, the first bridge portion 310, the second sub-bridge connection portion 321, the second sub-bridge connection portion 421, and the signal lead-in line 120-1.

[0142] Furthermore, the second sub-bridge connection portion 422 is electrically connected to the second sub-bridge connection portion 322 via the third transfer via GZ3, and the second sub-bridge connection portion 422 is electrically connected to the signal introduction line 120-2 via the fourth transfer via GZ4. In this way, the signal stv_b input by the second signal introduction portion 220 can be input to the input signal terminal IP of the fourth-stage shift register SR(4) through the first bridge connection portion 410, the first bridge portion 310, the second sub-bridge connection portion 322, the second sub-bridge connection portion 422, and the signal introduction line 120-2 in sequence.

[0143] Furthermore, the second sub-bridge connection portion 423 is electrically connected to the second sub-bridge connection portion 323 via the third transfer via GZ3, and the second sub-bridge connection portion 423 is electrically connected to the signal introduction line 120-3 via the fourth transfer via GZ4. In this way, the signal stv_b input by the second signal introduction portion 220 can be input to the input signal terminal IP of the sixth-stage shift register SR (6) through the first bridge connection portion 410, the first bridge portion 310, the second sub-bridge connection portion 323, the second sub-bridge connection portion 423, and the signal introduction line 120-3 in sequence.

[0144] Exemplarily, the third transfer via GZ3 penetrates the interlayer insulating layer, and the fourth transfer via GZ4 penetrates the gate insulating layer and the interlayer insulating layer.

[0145] In the embodiment of the present disclosure, Figure 5a and Figure 5d As shown, gaps can be provided between the plurality of second sub-bridge connections, and the orthographic projections of the plurality of second sub-bridge connections on the substrate substrate do not overlap with the orthographic projections of the signal lead-in wires in the first line group on the substrate substrate. This reduces the overlapping area between the second sub-bridge connections and the signal lead-in wires in the first line group, thereby reducing signal interference.

[0146] For example, the total number of third transfer vias GZ3 and fourth transfer vias GZ4 corresponding to a second sub-bridge connection portion can be the same. For example, the total number of third transfer vias GZ3 and fourth transfer vias GZ4 corresponding to a second sub-bridge connection portion can both be 1, 2, 3, or another number. Alternatively, the total number of third transfer vias GZ3 and fourth transfer vias GZ4 corresponding to a second sub-bridge connection portion can also be different. Of course, in actual applications, the total number of corresponding third transfer vias GZ3 and fourth transfer vias GZ4 can be designed and determined based on the needs of the actual application and is not limited here.

[0147] The present disclosure provides some other structural diagrams of display panels, such as Figures 7a to 8 As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0148] In the embodiment of the present disclosure, Figures 7a to 8 As shown, the first signal introduction portion 210 may include: at least one first sub-signal introduction portion 211 and a third sub-signal introduction portion 213; wherein the third sub-signal introduction portion 213 is directly electrically connected to the first end of each signal introduction line in the first line group. Furthermore, the display panel may further include: a fifth bridge connection portion 450; wherein the fifth bridge connection portion 450 and the first bridge connection portion 410 are located on the same layer. Furthermore, the fifth bridge connection portion 450 is electrically connected to each of the first sub-signal introduction portions via a ninth transfer via GZ9, and is electrically connected to the third sub-signal introduction portion 213 via a tenth transfer via GZ10.

[0149] Since the second signal introduction part 220 needs to be electrically connected to the signal introduction line in the second line group through the bridge part, the resistance difference between the signal flow path stv_b corresponding to the second signal introduction part 220 to the signal introduction line in the second line group and the signal flow path stv_a corresponding to the first signal introduction part 210 to the signal introduction line in the first line group is relatively large, resulting in a difference in the delay when the signals stv_a and stv_b are input into the signal input terminal IP, which in turn results in a difference in the signals output from the output signal terminals GO of the first-stage shift register, the third-stage shift register, the fifth-stage shift register and the second-stage shift register, the fourth-stage shift register, and the sixth-stage shift register, resulting in different brightness of the corresponding sub-pixels, affecting the display effect. In the embodiment of the present disclosure, by dividing the first signal introduction part 210 into a first sub-signal introduction part 211 and a third sub-signal introduction part 213, and electrically connecting the first sub-signal introduction part 211 and the third sub-signal introduction part 213 through the fifth bridge connection part 450, the resistance between the current flow path from the first signal introduction part 210 to the signal introduction line in the first line group can be increased, thereby reducing the voltage difference between the signal flow path stv_a and the signal flow path stv_b, reducing the difference in delay when the signals stv_a and stv_b are input into the signal input terminal IP, and improving the display effect.

[0150] Exemplarily, the ninth transfer via GZ9 penetrates the gate insulating layer and the interlayer insulating layer, and the tenth transfer via GZ10 penetrates the gate insulating layer and the interlayer insulating layer.

[0151] For example, in the embodiment of the present disclosure, Figures 7a to 8As shown, the first signal introduction portion 210 may include: a first sub-signal introduction portion 211 and a third sub-signal introduction portion 213. The second signal introduction portion 220 includes a second sub-signal introduction portion 221, that is, the second signal introduction portion 220 serves as the second sub-signal introduction portion, so that the number of first sub-signal introduction portions 211 and second signal introduction portions 220 can be the same. Among them, the third sub-signal introduction portion 213 is directly electrically connected to the first end of each signal introduction line 110-1, 110-2, and 110-3 in the first line group. In addition, the first end of the fifth bridge connection portion 450 is electrically connected to the first sub-signal introduction portion through the ninth transfer via GZ9, and the second end of the fifth bridge connection portion 450 is electrically connected to the third sub-signal introduction portion 213 through the tenth transfer via GZ10. In actual applications, the first sub-signal introduction part is electrically connected to the bonding terminal (PAD) of the input signal stv_a, so that the signal stv_a input to the bonding terminal (PAD) can be input into the signal input terminal IP of the corresponding shift register through the first sub-signal introduction part, the fifth bridging connection part 450, the third sub-signal introduction part 213 and each signal introduction line 110-1, 110-2 and 110-3 in the first line group in sequence.

[0152] For example, in the embodiment of the present disclosure, Figures 7a to 8 As shown, the total number of the ninth transfer vias GZ9 and the total number of the second transfer vias GZ2 can be the same. For example, the total number of the ninth transfer vias GZ9 and the total number of the second transfer vias GZ2 can be set to 12, 8, 10, or another number. In actual applications, the total number of the ninth transfer vias GZ9 and the total number of the second transfer vias GZ2 can also be different. Of course, the total number of the ninth transfer vias GZ9 and the total number of the second transfer vias GZ2 can be designed and determined based on the needs of the actual application and are not limited here.

[0153] For example, in the embodiment of the present disclosure, Figures 7a to 8 As shown, the total number of the tenth transfer vias GZ10 can be the same as the total number of the first transfer vias GZ1. For example, the total number of the tenth transfer vias GZ10 and the total number of the first transfer vias GZ1 can be set to 12, 8, 10, or another number. In actual applications, the total number of the tenth transfer vias GZ10 and the total number of the first transfer vias GZ1 can also be different. Of course, the total number of the tenth transfer vias GZ10 and the total number of the first transfer vias GZ1 can be designed and determined based on the needs of the actual application and is not limited here.

[0154] The present disclosure provides some structural diagrams of display panels, such as Figures 9a to 10 As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0155] In the embodiment of the present disclosure, Figures 9a to 10 As shown, the signal lead-in line in the first line group includes a first signal lead segment and a second signal lead segment. Furthermore, the display panel further includes: a plurality of fourth bridging connections; wherein the fourth bridging connection and the first bridging connection 410 are located on the same layer; wherein, in the same signal lead-in line, the first signal lead segment and the second signal lead segment are electrically connected via the fourth bridging connection. Exemplarily, the plurality of fourth bridging connections can be spaced apart from each other. Furthermore, the orthographic projection of the fourth bridging connection on the substrate does not overlap with the signal lead-in line in the first line group, the fourth bridging connection, and the orthographic projection of the bridging connection on the substrate. This can further reduce signal interference.

[0156] For example, in the embodiment of the present disclosure, Figures 9a to 10 As shown, the signal lead-in lines in the first line group include a first signal lead segment and a second signal lead segment. Specifically, in signal lead-in line 110-1, first signal lead segment 110-1a and second signal lead segment 110-1b are electrically connected via a fourth bridge connection 440-1. In signal lead-in line 110-2, first signal lead segment 110-2a and second signal lead segment 110-2b are electrically connected via a fourth bridge connection 440-2. In signal lead-in line 110-3, first signal lead segment 110-3a and second signal lead segment 110-3b are electrically connected via a fourth bridge connection 440-3. This reduces the resistance difference between the signal lead-in lines in the first line group and the signal lead-in lines in the second line group, further reducing the delay of signals stv_a and stv_b, and further improving display quality.

[0157] For example, in the embodiment of the present disclosure, Figures 9a to 10As shown, the first end of the first signal lead segment 110-1a is directly electrically connected to the third sub-signal introduction portion 213, the second end of the first signal lead segment 110-1a is electrically connected to the first end of the corresponding fourth bridge connection portion 440-1 via the fifth transfer via GZ5, and the second end of the fourth bridge connection portion 440-1 is electrically connected to the second signal lead segment 110-1b via the sixth transfer via GZ6. Furthermore, the first end of the first signal lead segment 110-2a is directly electrically connected to the third sub-signal introduction portion 213, the second end of the first signal lead segment 110-2a is electrically connected to the first end of the corresponding fourth bridge connection portion 440-2 via the fifth transfer via GZ5, and the second end of the fourth bridge connection portion 440-2 is electrically connected to the second signal lead segment 110-2b via the sixth transfer via GZ6. In addition, the first end of the first signal lead segment 110-3a is directly electrically connected to the third sub-signal introduction part 213, the second end of the first signal lead segment 110-3a is electrically connected to the first end of the corresponding fourth bridging connection part 440-3 through the fifth transfer via GZ5, and the second end of the fourth bridging connection part 440-3 is electrically connected to the second signal lead segment 110-3b through the sixth transfer via GZ6.

[0158] Exemplarily, the fifth transfer via GZ5 passes through the gate insulating layer and the interlayer insulating layer, and the sixth transfer via GZ6 passes through the gate insulating layer and the interlayer insulating layer.

[0159] For example, in the embodiment of the present disclosure, Figures 9a to 10 As shown, the second ends of the first signal lead segments in the first wire group are spaced apart from each other. Furthermore, a gap is provided between the second ends of the first signal lead segments in the first wire group. For example, the orthographic projections of the second ends of the first signal lead segments in the first wire group on the substrate do not overlap with the orthographic projections of the signal lead-in lines in the second wire group on the substrate.

[0160] For example, in the disclosed embodiment, when the signal lead-in line in the first line group includes a first signal lead segment and a second signal lead segment, the total number of fifth transfer vias GZ5 corresponding to a fourth bridge connection portion and the total number of third transfer vias GZ3 corresponding to a second bridge connection portion 420 can be the same. For example, the total number of fifth transfer vias GZ5 corresponding to a fourth bridge connection portion and the total number of third transfer vias GZ3 corresponding to a second bridge connection portion 420 can both be 2, 3, 1, or another number. Alternatively, the total number of fifth transfer vias GZ5 corresponding to a fourth bridge connection portion and the total number of third transfer vias GZ3 corresponding to a second bridge connection portion 420 can also be different. Of course, in actual applications, the total number of fifth transfer vias GZ5 corresponding to a fourth bridge connection portion and the total number of third transfer vias GZ3 corresponding to a second bridge connection portion 420 can be designed and determined based on the needs of the actual application and are not limited here.

[0161] For example, in the disclosed embodiment, when the signal lead-in line in the first line group includes a first signal lead segment and a second signal lead segment, the total number of sixth transfer vias GZ6 corresponding to a fourth bridge connection portion and the total number of fourth transfer vias GZ4 corresponding to a second bridge connection portion 420 can be the same. For example, the total number of sixth transfer vias GZ6 corresponding to a fourth bridge connection portion and the total number of fourth transfer vias GZ4 corresponding to a second bridge connection portion 420 can both be 2, 3, 1, or another number. Alternatively, the total number of sixth transfer vias GZ6 corresponding to a fourth bridge connection portion and the total number of fourth transfer vias GZ4 corresponding to a second bridge connection portion 420 can also be different. Of course, in actual applications, the total number of sixth transfer vias GZ6 corresponding to a fourth bridge connection portion and the total number of fourth transfer vias GZ4 corresponding to a second bridge connection portion 420 can be designed and determined based on the needs of the actual application and are not limited here.

[0162] The present disclosure provides some structural diagrams of display panels, such as Figures 11a to 11d As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0163] In the embodiment of the present disclosure, Figures 11a to 11d As shown, the second ends of the first signal lead segments in the first wire group can be brought into contact with each other to form an integrated structure. In other words, the orthographic projection of the integrated structure formed by the second ends of the first signal lead segments in the first wire group contacting each other has an overlapping area with the orthographic projection of the signal lead-in wires in the second wire group on the substrate.

[0164] In the embodiment of the present disclosure, Figures 11a to 11d As shown, multiple second sub-bridge portions can be brought into contact with each other to form an integrated structure. In other words, the orthographic projection of the integrated structure formed by the multiple second sub-bridge portions on the substrate overlaps with the orthographic projection of the signal lead-in wires in the first wire group on the substrate. For example, the three second sub-bridge portions included in the second bridging connection portion 420 may be brought into contact with each other to form an integrated structure.

[0165] The present disclosure provides some structural diagrams of display panels, such as Figure 12a and Figure 12b As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0166] In the disclosed embodiment, the second signal introduction unit 220 includes: at least one second sub-signal introduction unit; a first bridging connection unit 410 electrically connected to each second sub-signal introduction unit via a second transfer via GZ2; and the total number of first sub-signal introduction units is the same as the total number of second sub-signal introduction units. The total number of first sub-signal introduction units and the total number of second sub-signal introduction units can be the same.

[0167] For example, Figure 12a and Figure 12b As shown, the first signal introduction portion 210 may include: two first sub-signal introduction portions 211-1, 211-2 and a third sub-signal introduction portion 213. The second signal introduction portion 220 may include: two second sub-signal introduction portions 221-1, 221-2. The fifth bridging connection portion 450 is electrically connected to the first sub-signal introduction portions 211-1, 211-2 via the ninth transfer via GZ9, and the fifth bridging connection portion 450 is electrically connected to the third sub-signal introduction portion 213 via the tenth transfer via GZ10. Furthermore, the first bridging connection portion 410 is electrically connected to the second sub-signal introduction portions 221-1, 221-2 via the second transfer via GZ2.

[0168] Of course, the total number of first sub-signal introduction sections and the total number of second sub-signal introduction sections can also be set to 3, 4, or more, and this is not limited here. Of course, the total number of first sub-signal introduction sections and the total number of second sub-signal introduction sections can also be different. In actual applications, the total number of first sub-signal introduction sections and the total number of second sub-signal introduction sections can be designed and determined based on actual application requirements and are not limited here.

[0169] The present disclosure provides some structural diagrams of display panels, such as Figure 13a and Figure 13b As shown, the embodiment described above is modified.

[0205] The present disclosure provides some structural diagrams of display panels, such as Figures 17a to 17d As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0206] In the embodiment of the present disclosure, Figures 17a to 17dAs shown, the display panel may further include: a plurality of third auxiliary parts (such as 530-1, 530-2, and 530-3); the third auxiliary parts and the first auxiliary part 510 and the bridging part are located in the same layer; at least one third auxiliary part is correspondingly provided for a signal lead-in line in the first line group; wherein, in the same signal lead-in line, the first signal lead segment is electrically connected to the second signal lead segment through the corresponding third auxiliary part. Exemplarily, the display panel also includes: a plurality of sixth bridge adapter portions and a plurality of seventh bridge adapter portions; wherein, at least one third auxiliary portion is correspondingly provided with at least one sixth bridge adapter portion and at least one seventh bridge adapter portion; the first end of the third auxiliary portion is electrically connected to the corresponding sixth bridge adapter portion through the eleventh transfer via GZ11, the sixth bridge adapter portion is electrically connected to the corresponding first signal lead segment through the twelfth transfer via GZ12, the second end of the third auxiliary portion is electrically connected to the corresponding seventh bridge adapter portion through the seventeenth transfer via GZ17, and the seventh bridge adapter portion is electrically connected to the corresponding seventh bridge adapter portion through the eighteenth transfer via GZ18.

[0207] Illustratively, the eleventh transfer via GZ11 penetrates the interlayer insulating layer, the twelfth transfer via GZ12 penetrates the gate insulating layer and the interlayer insulating layer, the seventeenth transfer via GZ17 penetrates the interlayer insulating layer, and the eighteenth transfer via GZ18 penetrates the gate insulating layer and the interlayer insulating layer.

[0208] For example, Figures 17a to 17d As shown, the signal lead-in line 110-1 is provided with a third auxiliary portion 530-1, a sixth bridge adapter portion 460-1, and a seventh bridge adapter portion 470-1. The first signal lead segment 110-1a is electrically connected to the sixth bridge adapter portion 460-1 via the twelfth transfer via GZ12. The sixth bridge adapter portion 460-1 is electrically connected to the first end of the third auxiliary portion 530-1 via the eleventh transfer via GZ11. The second end of the third auxiliary portion 530-1 is electrically connected to the seventh bridge adapter portion 470-1 via the seventeenth transfer via GZ17. The seventh bridge adapter portion 470-1 is electrically connected to the second signal lead segment 110-1b via the eighteenth transfer via GZ18. This further reduces the difference in resistance between the signal lead-in lines in the first line group and the second line group. The remaining details are similar and are not further described here.

[0209] The present disclosure provides some structural diagrams of display panels, such as Figures 18a to 19 As shown, the embodiment described above is modified. The following only describes the differences between this embodiment and the above embodiment, and the similarities are not repeated here.

[0210] In the embodiment of the present disclosure, Figures 18a to 19As shown, the bridge portion may include a fourth bridge portion 340, a sixth bridge portion, and a fifth bridge portion connected between the fourth bridge portion 340 and the sixth bridge portion. The fourth bridge portion 340 is electrically connected to the second signal introduction portion 220 via a first conductive via GK1, and the sixth bridge portion is electrically connected to the signal introduction line in the second line group via a second conductive via GK2. Exemplarily, the fifth bridge portion includes a plurality of fifth sub-bridge portions (e.g., 351, 352, 353) spaced apart from each other; the sixth bridge portion includes a plurality of sixth sub-bridge portions (e.g., 361, 362, 363) spaced apart from each other; and the fourth bridge portion 340 is electrically connected to a signal introduction line in the second line group via at least one fifth sub-bridge portion and at least one sixth sub-bridge portion.

[0211] For example, the second signal introduction portion 220 is electrically connected to the fourth bridge portion 340 via the first conductive via GK1. The sixth sub-bridge portion 361 is directly electrically connected to the fifth sub-bridge portion 351. The fifth sub-bridge portion 351 is electrically connected to the signal introduction line 120-1 via the second conductive via GK2. Furthermore, the sixth sub-bridge portion 362 is directly electrically connected to the fifth sub-bridge portion 352.

The fifth sub-bridge portion 353 is electrically connected to the signal introduction line 120-3 via the second conductive via GK2.

[0213] Since the second signal introduction part 220 needs to be electrically connected to the signal introduction line in the second line group through the bridge part, the resistance difference between the signal flow path stv_b corresponding to the second signal introduction part 220 to the signal introduction line in the second line group and the signal flow path stv_a corresponding to the first signal introduction part 210 to the signal introduction line in the first line group is relatively large, resulting in a difference in the delay when the signals stv_a and stv_b are input into the signal input terminal IP, which in turn results in a difference in the signals output from the output signal terminals GO of the first-stage shift register, the third-stage shift register, the fifth-stage shift register and the second-stage shift register, the fourth-stage shift register, and the sixth-stage shift register, resulting in different brightness of the corresponding sub-pixels, affecting the display effect. In the embodiment of the present disclosure, a first hollow area KB1 is provided on the first signal introduction portion 210, and a first coupling via GH1 and a first coupling slit GF1 are provided in the first hollow area KB1, which penetrate the second signal introduction portion 220. This increases the resistance of the first signal introduction portion 210, thereby reducing the voltage difference between the signal flow path stv_a and the signal flow path stv_b, and reducing the difference in delay when the signals stv_a and stv_b are input into the signal input terminal IP, thereby improving the display effect.

[0214] In the disclosed embodiment, the total number of first coupling vias GH1 and the total number of first conductive vias GK1 can be set to be the same. For example, the total number of first coupling vias GH1 and the total number of first conductive vias GK1 can be set to 12, 8, or another number, without limitation herein. Of course, the total number of first coupling vias GH1 and the total number of first conductive vias GK1 can also be set to be different, which can be determined based on actual application requirements and is not limited herein.

[0215] In the embodiment of the present disclosure, Figures 18a to 19 As shown, the display panel may further include a fourth auxiliary portion 540 and a fifth auxiliary portion 550. The fourth auxiliary portion 540 and the fifth auxiliary portion 550 are located on the same layer as the bridge portion. The fourth auxiliary portion 540 is electrically connected to the first signal introduction portion 210 via a third conductive via GK3, and the fifth auxiliary portion 550 is electrically connected to the second signal introduction portion 220 via a fourth conductive via GK4. The fourth auxiliary portion 540, electrically connected to the first signal introduction portion 210, can reduce the resistance of the path through which the signal stv_a flows. Furthermore, the fifth auxiliary portion 550, electrically connected to the second signal introduction portion 220, can reduce the resistance of the path through which the signal stv_b flows.

[0216] In the embodiment of the present disclosure, Figures 18a to 19As shown, the signal lead-in lines in the first line group can include a second hollowed-out region (e.g., KB-1, KB-2, and KB-3). The second hollowed-out region includes a second bonding via GH2 and a second bonding slit GF2. The second bonding via GH2 penetrates the signal lead-in lines in the first line group, and the second bonding slit GF2 penetrates the signal lead-in lines in the first line group. This can increase the resistance of the signal lead-in lines in the first line group, further reducing the difference in resistance between the flow paths of the signal stv_a and stv_b.

[0217] In the embodiment of the present disclosure, Figures 18a to 19 As shown, the second hollowed-out area (e.g., KB-1, KB-2, and KB-3) further includes: a second bonding via GH2, which penetrates the signal lead-in wire in the first wire group and is located on the side of the second bonding slit GF2 facing away from the first bonding via GH1; and a fourth bonding via GH4, which is provided at one end of the signal lead-in wire in the second wire group connected to the fifth sub-bridge portion; the fourth bonding via GH4 is located on the side of the second conductive via GK2 facing away from the sixth sub-bridge portion. This further reduces the difference in resistance between the flow path of the signal stv_a and the flow path of the signal stv_b.
