[0045] In the embodiment of the present invention, the shift register in the gate driving circuit is divided into two register groups. In an actual application example, the shift register in the gate driving circuit can be divided into three register groups, four register groups, or more register groups, but is not limited thereto.

[0046] In an actual application example, the frame start signal end is electrically connected to the input signal end IP of the shift register through a signal lead. However, currently, the signal lead lines corresponding to the start signal ends of the same frame are set in the same area, and no other signal lines are provided between the signal lead lines corresponding to the start signal ends of the same frame. This is not useful for wiring the signal lead lines.

[0047] In an embodiment of the present invention, a plurality of signal lead-in lines are also provided in the non-display area. The plurality of signal lead-in lines are divided into a plurality of line groups, and one line group is electrically connected to one register group. And, between two signal lead-in lines of the same line group, there is a signal lead-in line of another line group. These plurality of signal lead-in lines may be, for example, signal lines electrically connecting a frame start signal end and an input signal end IP of a shift register. Alternatively, these plurality of signal lead-in lines may be clock signal lines. Or they may be other function signal lines.

[0048] For example, when these signal lead-in lines are signal lines electrically connecting the frame start signal end and the input signal end IP of the shift register, in the embodiment of the present invention, as shown in conjunction with Figures 2, 3a, 5a and 5b, the signal lead-in lines can be divided into two line groups, where the first line group of the two line groups includes signal input lines 110-1, 110-2, 110-3, and the first line group is connected to the frame start signal end STV_A of the first register group X1. Here, the signal lead-in line 110-1 is connected between the frame start signal end STV_A and the input signal end IP of the first stage shift register SR(1), the signal lead-in line 110-2 is connected between the frame start signal end STV_A and the input signal end IP of the third stage shift register SR(3), and the signal lead-in line 110-3 is connected between the frame start signal end STV_A and the input signal end IP of the fifth stage shift register SR(5).

[0049] As shown in FIG. 2, FIG. 3b, FIG. 5a, FIG. 5b, and FIG. 6, the second line group of the two line groups includes signal lead-in lines 120-1, 120-2, and 120-3. The second line group is also connected to the frame start signal end STV_B of the second register group X2. Here, the signal lead-in line 120-1 is connected between the frame start signal end STV_B and the input signal end IP of the second stage shift register SR(2). The signal lead-in line 120-2 is connected between the frame start signal end STV_B and the input signal end IP of the fourth stage shift register SR(4). The signal lead-in line 120-3 is connected between the frame start signal end STV_B and the input signal end IP of the sixth stage shift register SR(6).

[0050] 5a and 5b, the signal lead-in lines of the first line group and the signal lead-in lines of the second line group are arranged alternately. For example, the signal lead-in lines 120-3, 110-3, 120-2, 110-2, 120-1, and 110-1 are arranged in order in the direction of the F1 arrow. This optimizes the wiring space.

[0051] In one embodiment of the present invention, a transistor is provided in a subpixel of a display panel, the transistor having a gate electrode, an active layer, and source and drain electrodes. Here, the gate electrode and the gate line are disposed in the same layer and made of the same material, the source and drain electrodes and the data line are disposed in the same layer and made of the same material, the active layer is located between the layer in which the gate line is located and the layer in which the data line is located. In addition, a gate insulating layer is provided between the layer in which the gate line is located and the layer in which the active layer is located, and an interlayer insulating layer (e.g., PVX) is provided between the layer in which the active layer is located and the layer in which the data line is located.

[0052] In the embodiment of the present invention, the signal lead-in line may be provided in the same layer and material as the gate line. In this way, when preparing the gate line, the pattern of the original mask only needs to be changed when forming the pattern of the gate line, and the pattern of the gate line and the pattern of the signal lead-in line can be formed at the same time. Without adding a process of preparing the signal lead-in line, the preparation process can be simplified with one patterning process, which can save production costs and improve production efficiency.

[0053] In an embodiment of the present invention, the display panel further includes a plurality of signal introduction parts and a plurality of bridge parts, and the signal introduction parts and the signal lead-in lines are located in the same layer. One of the plurality of line groups is electrically connected to the signal introduction part in the plurality of signal introduction parts. Also, one of the plurality of line groups is electrically connected directly to the corresponding signal introduction part, and the remaining line groups are electrically connected to the corresponding signal introduction part through the bridge part. For example, when these plurality of signal introduction lines are signal lines electrically connecting the frame start signal end and the input signal end IP of the shift register, in an embodiment of the present invention, the plurality of signal introduction parts include a first signal introduction part 210 and a second signal introduction part 220. As shown in FIG. 2, FIG. 3a, FIG. 5a to FIG. 6, the first signal introduction part 210 is an integral structure formed of the same film layer material, and the signal introduction lines 110-1, 110-2 and 110-3 of the first line group can be directly electrically connected to the first signal introduction part 210. That is, the signal lead-in lines 110-1, 110-2, and 110-3 of the first line group are an integral structure formed of the same film layer as the first signal introducing section 210. The signal lead-in lines 120-1, 120-2, and 120-3 of the second line group are electrically connected to the second signal introducing section 220 via the bridge section 300. That is, there are gaps between the signal lead-in lines 120-1, 120-2, and 120-3 of the second line group and the second signal introducing section 220.

[0054] Specifically, the first ends of the signal lead-in lines 110-1, 110-2, and 110-3 of the first line group can be directly electrically connected to the first signal introducing section 210. The second ends of the signal lead-in lines 110-1, 110-2, and 110-3 of the first line group are electrically connected to the input signal ends IP of the shift registers of the first register group, respectively. In this manner, the signal stv_a input by the first signal introducing section 210 is directly input to the input signal end IP of the second-stage shift register SR(1) via the signal lead-in line 110-1. Then, the signal stv_a input from the first signal introducing section 210 is directly input to the input signal end IP of the third-stage shift register SR(3) via the signal lead-in line 110-2. Then, the signal stv_a input from the first signal introducing section 210 is directly input to the input signal end IP of the fifth-stage shift register SR(5) via the signal lead-in line 110-3.

[0055] The first ends of the signal lead-in lines 120-1, 120-2, and 120-3 of the second line group are electrically connected to the second signal introducing unit 220 via the bridge unit 300. The second ends of the signal lead-in lines 120-1, 120-2, and 120-3 of the second line group are electrically connected to the input signal terminals IP of the shift registers of the second register group. As a result, the signal stv_b input from the second signal introducing unit 220 is input to the input signal terminal IP of the second stage shift register SR(2) via the bridge connection in order through the bridge unit 300 and the signal lead-in line 120-1. And, the signal stv_b input from the second signal introducing unit 220 is input to the input signal terminal IP of the fourth stage shift register SR(4) via the bridge connection in order through the bridge unit 300 and the signal lead-in line 120-2. Then, via the bridge connection, the signal stv_b input from the second signal introducing section 220 is input in this order to the bridge section 300 and the input signal terminal IP of the sixth stage shift register SR(6) via the signal lead-in line 120-3.

[0056] In the embodiment of the present invention, the bridge portion and the signal introduction portion are located on different layers. For example, the bridge portion and the data line may be arranged on the same layer with the same material. In this way, when preparing the data line, the pattern of the data line and the pattern of the bridge portion can be formed simultaneously by simply changing the patterning pattern of the original mask during the patterning of the data line. The process of the bridge portion does not need to be prepared separately, and the preparation process can be simplified with one patterning process, which saves production costs and improves production efficiency.

[0057] In the embodiment of the present invention, as shown in Figs. 5a to 6, the bridge section may include a first bridge section 310, a second bridge section 320, and a third bridge section 330 connected between the first bridge section 310 and the second bridge section 320. And, the display panel may include a first bridge connection section 410 and a second bridge connection section 420. Here, the first bridge connection section 410, the bridge section, and the signal introduction section are located in different layers, and the second bridge connection section 420 and the first bridge connection section 410 are located in the same layer. For example, when the display panel is a liquid crystal display panel, the first bridge connection section 410 and the second bridge connection section 420 may be provided in the same layer and made of the same material as the pixel electrodes.

[0058] In the embodiment of the present invention, as shown in Fig. 5a to Fig. 6, a first end of the first bridge connection part 410 is electrically connected to the first bridge part 310 through the first turn via hole GZ1, and a second end of the first bridge connection part 410 is electrically connected to the second signal introduction part 220 through the second turn via hole GZ2. And, a first end of the second bridge connection part 420 is electrically connected to the second bridge part 320 through the third turn via hole GZ3. A second end of the second bridge connection part 420 is electrically connected to the signal lead-in line of the second line group through the fourth turn via hole GZ4.

[0059] Exemplarily, the first turn via hole GZ1 penetrates the interlayer insulating layer, and the second turn via hole GZ2 penetrates the gate insulating layer and the interlayer insulating layer.

[0060] Exemplarily, the total number of the first turn via holes GZ1 and the total number of the second turn via holes GZ2 may be the same. For example, the total number of the first turn via holes GZ1 and the total number of the second turn via holes GZ2 may be 12, 10, 8, etc. Or, the total number of the first turn via holes GZ1 and the total number of the second turn via holes GZ2 may be different. Of course, in practical applications, the total number of the first turn via holes GZ1 and the total number of the second turn via holes GZ2 can be designed and determined according to the needs of practical applications, and is not limited here.

[0061] In the embodiment of the present invention, as shown in Figs. 5a to 6, the third bridge unit 330 may include a plurality of third sub-bridge units spaced apart from each other, and the second bridge unit 320 may include a plurality of second sub-bridge units. Here, one third sub-bridge unit corresponds to one signal lead-in line. One second sub-bridge unit corresponds to one signal lead-in line. For example, when the second line group has signal lead-in lines 120-1, 120-2, and 120-3, the signal lead-in line 120-1 corresponds to the third sub-bridge unit 331 and the second sub-bridge unit 321, and the signal lead-in line 120-1 is electrically connected to the first bridge unit 310 via the second sub-bridge unit 321 and the third sub-bridge unit 331 in order. The signal lead-in line 120-2 corresponds to the third sub-bridge unit 332 and the second sub-bridge unit 322, and the signal lead-in line 120-2 is electrically connected to the first bridge unit 310 via the second sub-bridge unit 322 and the third sub-bridge unit 332 in this order. The signal lead-in line 120-3 corresponds to the third sub-bridge unit 333 and the second sub-bridge unit 323, and the signal lead-in line 120-3 is electrically connected to the first bridge unit 310 via the second sub-bridge unit 323 and the third sub-bridge unit 333 in this order. In this way, a signal transmission path is formed. Furthermore, by arranging a plurality of third sub-bridge units at intervals, the overlapping area between the third sub-bridge unit and the signal lead-in line of the first line group can be reduced, and signal interference can be reduced.

[0062] In the embodiment of the present invention, the shape of the third sub-bridge portion may be a non-linear shape, for example, as shown in FIG. 5c, the shape of the third sub-bridge portion (331, 332, 333) may be a broken line shape. Also, the third sub-bridge portion (331, 332, 333) may be a broken line shape consisting of three straight lines, with two bending angles, and the bending angles may be obtuse angles. Or, the shape of the third sub-bridge portion may be a curved line. Also, the third sub-bridge portion may be formed by a circular arc curve. Of course, in practical applications, the shape of the third sub-bridge portion may be determined according to the requirements of practical applications, and is not limited here.

[0063] In an embodiment of the present invention, as shown in Figures 5a, 5c, and 6, a plurality of second sub-bridge units may be spaced apart from each other. For example, there are gaps between the second sub-bridge units 321, 322, and 323, and the orthogonal projections of the plurality of second sub-bridge units on the base substrate do not overlap with the orthogonal projections of the signal lead-in lines of the first line group on the base substrate. This can reduce the overlapping area between the second sub-bridge units and the signal lead-in lines of the first line group, thereby reducing signal interference.

[0064] In the embodiment of the present invention, as shown in Figs. 5a to 6, the second bridge connection section 420 includes a plurality of second sub-bridge connection sections spaced apart from each other, where one second sub-bridge section is electrically connected to one second sub-bridge connection section via the third turn via hole GZ3. For example, the second bridge connection section 420 includes three second sub-bridge connection sections 421, 422, and 423 spaced apart from each other. Here, the second sub-bridge connection section 421 is electrically connected to the second sub-bridge section 321 via the third turn via hole GZ3, and the second sub-bridge connection section 421 is electrically connected to the signal lead-in line 120-1 via the fourth turn via hole GZ4. In this way, the signal stv_b input from the second signal introduction section 220 is input to the input signal terminal IP of the second stage shift register SR(2) via the first bridge connection section 410, the first bridge section 310, the second sub-bridge section 321, the second sub-bridge connection section 421, and the signal lead-in line 120-1 in sequence.

[0065] The second sub-bridge connection section 422 is electrically connected to the second sub-bridge section 322 through the third turn via hole GZ3, and the second sub-bridge connection section 422 is electrically connected to the signal lead-in line 120-2 through the fourth turn via hole GZ4. In this manner, the signal stv_b input from the second signal introducing section 220 is input to the input signal terminal IP of the fourth stage shift register SR(4) via the first bridge connection section 410, the first bridge section 310, the second sub-bridge section 322, the second sub-bridge connection section 422, and the signal lead-in line 120-2 in this order.

[0066] The second sub-bridge connection section 423 is electrically connected to the second sub-bridge section 323 through the third turn via hole GZ3, and the second sub-bridge connection section 423 is electrically connected to the signal lead-in line 120-3 through the fourth turn via hole GZ4. In this manner, the signal stv_b input from the second signal introducing section 220 is input to the input signal terminal IP of the sixth stage shift register SR(6) via the first bridge connection section 410, the first bridge section 310, the second sub-bridge section 323, the second sub-bridge connection section 423, and the signal lead-in line 120-3 in this order.

[0067] Exemplarily, the third turn via hole GZ3 penetrates the interlayer insulating layer, and the fourth turn via hole GZ4 penetrates the gate insulating layer and the interlayer insulating layer.

[0068] In an embodiment of the present invention, as shown in Figures 5a and 5d, gaps may be formed between the second sub-bridge connections, and the orthogonal projections of the second sub-bridge connections on the base substrate do not overlap with the orthogonal projections of the signal lead-in lines of the first line group on the base substrate, thereby reducing the overlapping area between the second sub-bridge connections and the signal lead-in lines of the first line group, and reducing signal interference.

[0069] Exemplarily, the total number of the third turn via holes GZ3 and the fourth turn via holes GZ4 corresponding to one second sub-bridge connection part may be the same. For example, the total number of the third turn via holes GZ3 and the fourth turn via holes GZ4 corresponding to one second sub-bridge connection part may be one, two, three, etc. Or, the total number of the third turn via holes GZ3 and the fourth turn via holes GZ4 corresponding to one second sub-bridge connection part may be different. Of course, in practical applications, the total number of the corresponding third turn via holes GZ3 and the fourth turn via holes GZ4 can be designed and determined according to the needs of practical applications, and is not limited here.

[0070] The embodiment of the present invention provides a schematic structural diagram of another display panel which is modified from the implementation of the above embodiment, as shown in Figures 7a to 8. Hereinafter, only the differences between this embodiment and the above embodiment will be described, and the description of the similarities will be omitted.

[0071] In the embodiment of the present invention, as shown in FIG. 7a to FIG. 8, the first signal introducing portion 210 includes at least one first sub-signal introducing portion 211 and a third sub-signal introducing portion 213. Here, the third sub-signal introducing portion 213 is directly electrically connected to the first end of each signal lead-in line in the first line group. In addition, the display panel further includes a fifth bridge connection portion 450. Here, the fifth bridge connection portion 450 and the first bridge connection portion 410 are located in the same layer. In addition, the fifth bridge connection portion 450 is electrically connected to each first sub-signal introducing portion through a ninth turn via hole GZ9, and the fifth bridge connection portion 450 is electrically connected to the third sub-signal introducing portion 213 through a tenth turn via hole GZ10.

[0072] Since the second signal introducing part 220 is electrically connected to the signal lead-in line of the second line group through the bridge part, there is a large resistance difference between the signal flow path from the second signal introducing part 220 to stv_b corresponding to the signal lead-in line of the second line group and the signal flow path from the first signal introducing part 210 to stv_a corresponding to the signal lead-in line of the first line group, and a difference occurs in the delay when the signals stv_a and stv_b are input to the signal input terminal IP. The signals output from the first stage shift register, the third stage shift register, and the fifth stage shift register are different from the signals output from the output signal terminal GO of the second stage shift register, the fourth stage shift register, and the sixth stage shift register, so that the brightness of the corresponding sub-pixels is different, which affects the display effect. In the embodiment of the present invention, the first signal introducing section 210 is divided into the first sub-signal introducing section 211 and the third sub-signal introducing section 213, and the first sub-signal introducing section 211 and the third sub-signal introducing section 213 are electrically connected via the fifth bridge connection section 450, so that the resistance between the current path from the first signal introducing section 210 to the signal lead-in line of the first line group can be increased. This reduces the voltage difference between the stv_a signal flow path and the stv_b signal flow path, and reduces the delay difference when the signals stv_a and stv_b are input to the signal input terminal IP, improving the display.

[0073] Exemplarily, the ninth turn via hole GZ9 penetrates the gate insulating layer and the interlayer insulating layer, and the tenth turn via hole GZ10 penetrates the gate insulating layer and the interlayer insulating layer.

[0074] Illustratively, in the embodiment of the present invention, as shown in Fig. 7a to Fig. 8, the first signal introducing section 210 may include one first sub-signal introducing section 211 and a third sub-signal introducing section 213. The second signal introducing section 220 includes one second sub-signal introducing section 221, that is, the second signal introducing section 220 functions as the second sub-signal introducing section, so that the number of the first sub-signal introducing sections 211 and the second sub-signal introducing sections 211 is the same. Here, the third sub-signal introducing section 213 is directly electrically connected to the first ends of the signal lead-in lines 110-1, 110-2, and 110-3 in the first line group. Also, a first end of the fifth bridge connection section 450 is electrically connected to the first sub-signal introduction section through the ninth turn via hole GZ9, and a second end of the fifth bridge connection section 450 is electrically connected to the third sub-signal introduction section 213 through the tenth turn via hole GZ10. In actual application, the first sub-signal introduction section is electrically connected to a bonding terminal (PAD) that inputs the signal stv_a. As a result, the signal stv_a input to the bonding terminal (PAD) is input to the signal input terminal IP of the corresponding shift register via the first sub-signal introduction section, the fifth bridge connection section 450, the third sub-signal introduction section 213, and each of the signal lead-in lines 110-1, 110-2, and 110-3 in the first line group in sequence.

[0075] Exemplarily, in the embodiment of the present invention, as shown in Figs. 7a to 8, the total number of the 9th turn via holes GZ9 and the total number of the second turn via holes GZ2 may be the same. For example, the total number of the 9th turn via holes GZ9 may be set to 12, 8, 10, etc. In practical applications, the total number of the 9th turn via holes GZ9 and the total number of the second turn via holes GZ2 may also be different. Of course, the total number of the 9th turn via holes GZ9 and the total number of the second turn via holes GZ2 can be designed and determined according to the needs of practical applications, and are not limited here.

[0076] Exemplarily, in the embodiment of the present invention, as shown in FIG. 7a to FIG. 8, the total number of the tenth turn via holes GZ10 and the total number of the first turn via holes GZ1 may be the same. For example, the total number of the tenth turn via holes GZ10 and the total number of the first turn via holes GZ1 may be set to 12, 8, 10, etc. In practical applications, the total number of the tenth turn via holes GZ10 and the total number of the first turn via holes GZ1 may also be different. Of course, the total number of the tenth turn via holes GZ10 and the total number of the first turn via holes GZ1 can be designed and determined according to the needs of practical applications, and is not limited here.

[0077] The embodiment of the present invention provides further structural schematic diagrams of a display panel, as shown in Figure 9a to Figure 10. Hereinafter, only the differences between this embodiment and the above-mentioned embodiments will be described, and the description of the similarities will be omitted.

[0078] In the embodiment of the present invention, as shown in FIG. 9a to FIG. 10, the signal lead-in line of the first line group includes one first signal lead segment and one second signal lead segment. In addition, the display panel further includes a plurality of fourth bridge connection parts. Here, the fourth bridge connection part and the first bridge connection part 410 are located in the same layer, and in the same signal lead-in line, the first signal lead segment and the second signal lead segment are electrically connected via the fourth bridge connection part. Exemplarily, the plurality of fourth bridge connection parts may be arranged spaced apart from each other. In addition, the orthogonal projection of the fourth bridge connection part on the base substrate does not overlap with the orthogonal projection of the signal lead-in line of the first line group, the fourth bridge connection part and the bridge part on the base substrate. This further reduces signal interference.

[0079] Exemplarily, in the embodiment of the present invention, as shown in Figs. 9a to 10, the signal lead line of the first line group includes one first signal lead segment and one second signal lead segment. Here, in the signal lead line 110-1, the first signal lead segment 110-1a and the second signal lead segment 110-1b are electrically connected via a fourth bridge connection portion 440-1. In the signal lead line 110-2, the first signal lead segment 110-2a and the second signal lead segment 110-2b are electrically connected via a fourth bridge connection portion 440-2. In the signal lead line 110-3, the first signal lead segment 110-3a and the second signal lead segment 110-3b are electrically connected via a fourth bridge connection portion 440-3. This can reduce the resistance difference between the signal lead-in lines of the first line group and the signal lead-in lines of the second line group, further reducing the delay of the signals stv_a and stv_b and further improving the display effect.

[0080] Exemplarily, in the embodiment of the present invention, as shown in FIG. 9a to FIG. 10, a first end of the first signal lead segment 110-1a is electrically connected directly to the third sub-signal introduction portion 213, and a second end of the first signal lead segment 110-1a is electrically connected to a first end of the corresponding fourth bridge connection portion 440-1 through a fifth turn via hole GZ5. A second end of the fourth bridge connection portion 440-1 is electrically connected to a second signal lead segment 110-1b through a sixth turn via hole GZ6. And, a first end of the first signal lead segment 110-2a is electrically connected directly to the third sub-signal introduction portion 213. A second end of the first signal lead segment 110-2a is electrically connected to a first end of the corresponding fourth bridge connection portion 440-2 through a fifth turn via hole GZ5. A second end of the fourth bridge connection portion 440-2 is electrically connected to the second signal lead segment 110-2b through the sixth turn via hole GZ6. A first end of the first signal lead segment 110-3a is directly electrically connected to the third sub-signal introduction portion 213. A second end of the first signal lead segment 110-3a is electrically connected to a first end of the corresponding fourth bridge connection portion 440-3 through the fifth turn via hole GZ5. A second end of the fourth bridge connection portion 440-3 is electrically connected to the second signal lead segment 110-3b through the sixth turn via hole GZ6.

[0081] Exemplarily, the fifth turn via hole GZ5 penetrates the gate insulating layer and the interlayer insulating layer, and the sixth turn via hole GZ6 penetrates the gate insulating layer and the interlayer insulating layer.

[0082] 9a-10, in an embodiment of the present invention, the second ends of each of the first signal lead segments in the first line group are spaced apart from each other. Also, a gap is provided between the second ends of each of the first signal lead segments in the first line group. For example, an orthogonal projection of the second ends of the first signal lead segments in the first line group on the base substrate does not overlap with an orthogonal projection of each of the signal lead-ins in the second line group on the base substrate.

[0083] Exemplarily, in an embodiment of the present invention, when the signal lead-in line of the first line group includes a first signal lead segment and one second signal lead segment, the total number of the fifth turn via holes GZ5 corresponding to one fourth bridge connection portion may be the same as the total number of the third turn via holes GZ3 corresponding to one second bridge connection portion 420. For example, the total number of the fifth turn via holes GZ5 corresponding to one fourth bridge connection portion and the total number of the third turn via holes GZ3 corresponding to one second bridge connection portion 420 may both be 2, 3, 1, or other numbers. Or, the total number of the fifth turn via holes GZ5 corresponding to one fourth bridge connection portion and the total number of the third turn via holes GZ3 corresponding to one second bridge connection portion 420 may be different. Of course, in actual applications, the total number of the fifth turn via holes GZ5 corresponding to one fourth bridge connection portion and the total number of the third turn via holes GZ3 corresponding to one second bridge connection portion 420 can be designed and determined according to the needs of actual applications, and is not limited here.

[0084] Exemplarily, in an embodiment of the present invention, when the signal lead-in line of the first line group includes one first signal lead segment and one second signal lead segment, the total number of the sixth turn via holes GZ6 corresponding to one fourth bridge connection portion may be the same as the total number of the fourth turn via holes GZ4 corresponding to one second bridge connection portion 420. For example, the total number of the sixth turn via holes GZ6 corresponding to one fourth bridge connection portion and the total number of the fourth turn via holes GZ4 corresponding to one second bridge connection portion 420 may both be 2, 3, 1, or other numbers. Or, the total number of the sixth turn via holes GZ6 corresponding to one fourth bridge connection portion and the total number of the fourth turn via holes GZ4 corresponding to one second bridge connection portion 420 may be different. Of course, in actual applications, the total number of the sixth turn via holes GZ6 corresponding to one fourth bridge connection portion and the total number of the fourth turn via holes GZ4 corresponding to one second bridge connection portion 420 can be designed and determined according to the needs of actual applications, and is not limited here.

[0085] The embodiment of the present invention provides further structural schematic diagrams of a display panel, as shown in Fig. 11a to Fig. 11d. Hereinafter, only the differences between this embodiment and the above-mentioned embodiments will be described, and the description of the similarities will be omitted.

[0086] In the embodiment of the present invention, as shown in Figures 11a to 11d, the second ends of the first signal lead segments in the first line group contact each other to form an integral structure, i.e., the orthogonal projection on the base substrate of the integral structure formed by the second ends of the first signal lead segments in the first line group contact each other has an overlapping region with the orthogonal projection on the base substrate of the signal lead-in lines of the second line group.

[0087] In the embodiment of the present invention, as shown in Figures 11a to 11d, the second sub-bridge parts are in contact with each other to form an integral structure. That is, the orthogonal projection of the integral structure formed by the second sub-bridge parts in contact with each other on the base substrate has an overlapping area with the orthogonal projection of the signal lead-in lines of the first line group on the base substrate. For example, the three second sub-bridge connection parts included in the second bridge connection part 420 are in contact with each other to form an integral structure.

[0088] The embodiment of the present invention provides a further structural schematic diagram of a display panel, as shown in Figure 12a and Figure 12b. Hereinafter, only the differences between this embodiment and the previous embodiment will be described, and the similarities will be omitted.

[0089] In an embodiment of the present invention, the second signal introducing section 220 includes at least one second sub-signal introducing section, the first bridge connection section 410 is electrically connected to each second sub-signal introducing section through a second turn via hole GZ2, and the total number of the first sub-signal introducing sections is the same as the total number of the second sub-signal introducing sections. The total number of the first sub-signal introducing sections may be the same as the total number of the second sub-signal introducing sections.

[0090] Exemplarily, as shown in FIG. 12a and FIG. 12b, the first signal introducing portion 210 may include two first sub-signal introducing portions 211-1, 211-2 and a third sub-signal introducing portion 213. The second signal introducing portion 220 may include two second sub-signal introducing portions 221-1, 221-2. Here, the fifth bridge connection portion 450 is electrically connected to the first sub-signal introducing portions 211-1, 211-2 through the ninth turn via hole GZ9, and the fifth bridge connection portion 450 is electrically connected to the third sub-signal introducing portion 213 through the tenth turn via hole GZ10. And the first bridge connection portion 410 is electrically connected to the second sub-signal introducing portions 221-1, 221-2 through the second turn via hole GZ2.

[0091] Of course, the total number of the first sub-signal introduction parts and the total number of the second sub-signal introduction parts can be three, four or more, but are not limited thereto. Of course, the total number of the first sub-signal introduction parts and the total number of the second sub-signal introduction parts can be different. In practical applications, the total number of the first sub-signal introduction parts and the total number of the second sub-signal introduction parts can be designed and determined according to the needs of practical applications, and are not limited here.

[0135] In the embodiment of the present invention, as shown in Figures 18a to 19, first signal introducing portion 210 includes a first hollow region KB1. Here, first hollow region KB1 includes a first bonding via hole GH1 and a first bonding slit GF1. Here, first bonding via hole GH1 and first bonding slit GF1 penetrate first signal introducing portion 210.

[0136] Since the second signal introducing section 220 needs to pass through a bridge section to electrically connect to the signal lead-in line of the second line group, there is a large resistance difference between the signal flow path of stv_b corresponding to the second signal introducing section 220 to the signal lead-in line of the second line group and the signal flow path of stv_a corresponding to the first signal introducing section 210 to the signal lead-in line of the first line group, and a difference occurs in delay when the signals stv_a and stv_b are input to the signal input terminal IP. Since the signals output from the output signal terminals GO of the first, third and fifth stage shift registers and the second, fourth and sixth stage shift registers are different, the brightness of the corresponding sub-pixels is different, which affects the display effect. In an embodiment of the present invention, a first hollow region KB1 is provided in the first signal introducing portion 210, and a first bonding via hole GH1 and a first bonding slit GF1 penetrating the second signal introducing portion 220 are provided in the first hollow region KB1, thereby increasing the resistance of the first signal introducing portion 210, reducing the voltage difference between the signal flow path of stv_a and the signal flow path of stv_b, and reducing the difference in delay when the signals stv_a and stv_b are input to the signal input terminal IP, thereby improving the display effect.

[0137] In the embodiment of the present invention, the total number of the first bonding via holes GH1 and the total number of the first conductive via holes GK1 can be set to be the same. For example, the total number of the first bonding via holes GH1 and the total number of the first conductive via holes GK1 can be set to 12, 8, or other numbers, but is not limited here. Of course, the total number of the first bonding via holes GH1 and the total number of the first conductive via holes GK1 can also be set to be different, and can be determined according to the actual application requirements, but is not limited here.

[0138] In the embodiment of the present invention, as shown in FIG. 18a to FIG. 19, the display panel further includes a fourth auxiliary part 540 and a fifth auxiliary part 550. The fourth auxiliary part 540 and the fifth auxiliary part 550 are located in the same layer as the bridge part, and the fourth auxiliary part 540 is electrically connected to the first signal introducing part 210 through the third conductive via hole GK3. The fifth auxiliary part 550 is electrically connected to the second signal introducing part 220 through the fourth conductive via hole GK4. In this way, by providing the fourth auxiliary part 540 electrically connected to the first signal introducing part 210, the resistance of the distribution path of the signal stv_a can be reduced. Furthermore, by providing the fifth auxiliary part 550 electrically connected to the second signal introducing part 220, the resistance of the distribution path of the signal stv_b can be reduced.

[0139] In the embodiment of the present invention, as shown in FIG. 18a to FIG. 19, the signal lead-in line of the first line group can include a second hollow area (KB-1, KB-2, KB-3, etc.). The second hollow area includes a second bonding via hole GH2 and a second bonding slit GF2. Here, the second bonding via hole GH2 penetrates the signal lead-in line of the first line group. The second bonding slit GF2 penetrates the signal lead-in line of the first line group. This can increase the resistance of the signal lead-in line of the first line group, and can reduce the difference between the resistance of the distribution path of the signal stv_a and the resistance of the distribution path of the signal stv_b.

[0140] In the embodiment of the present invention, as shown in FIG. 18a to FIG. 19, the second hollow area (for example, KB-1, KB-2, KB-3) also includes a second bonding via hole GH2, where the second bonding via hole GH2 penetrates the signal lead-in line of the first line group, and the second bonding via hole GH2 is located on the side of the second bonding slit GF2 that is away from the first bonding via hole GH1. A fourth bonding via hole GH4 is provided at one end of the signal lead-in line of the second line group that is connected to the fifth sub-bridge portion. Here, the fourth bonding via hole GH4 is located on the side of the second conductive via hole GK2 that is away from the sixth sub-bridge portion. This makes it possible to further reduce the difference between the resistance of the distribution path of the signal stv_a and the resistance of the distribution path of the signal stv_b.

[0141] In addition, in an actual process, due to limitations in process conditions, etc., the similarities described in the above embodiments may not be exactly the same, and there may be some deviations, so it is sufficient to have the similar relationship as pointed out above. In general, any conditions are sufficient to satisfy the above, and all of them are included in the scope of protection of the present invention.
