[0030] Hereinafter, the technical solutions of the embodiments of the present invention will be clearly and completely described with reference to the drawings of the embodiments, in order to further clarify the object, technical solutions and advantages of the embodiments of the present invention. It is clear that the embodiments described are part of the present invention and not all embodiments. Furthermore, embodiments and features in embodiments of the present invention may be combined without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without requiring creative work are within the scope of the protection of the present invention.

The terms “first,” “second,” and similar phrases used in this invention are not intended to indicate order, quantity, or importance, but are used simply to distinguish different components. Similar terms such as “contains” or “includes” mean that the element or object appearing before the term is equivalent to the element or object appearing after it, but do not exclude other elements or objects. Similar terms such as “connection” or “linking” are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0032] Furthermore, the dimensions and shapes of each pattern in the drawings do not reflect the true scale, but are intended to provide a general overview of the present invention. Also, reference numerals that are the same or similar from beginning to end represent the same or similar elements or elements having the same or similar functions.

[0033] Referring to Figure 1, the display panel may include a base substrate 100. The base substrate includes a display area and a non-display area surrounding the display area. The display area may include a plurality of pixel units arranged in an array, a plurality of gate lines GA (e.g., GA1, GA2, GA3, GA4), and a plurality of data lines DA (e.g., DA1, DA2, DA3). The non-display area may include a gate drive circuit 110 and a source drive circuit 120. For example, the gate drive circuit 110 is electrically connected to the gate lines GA1, GA2, GA3, and GA4, respectively, and the source drive circuit 120 is electrically connected to the data lines DA1, DA2, and DA3, respectively. Here, a signal is input to the gate drive circuit 110, and a signal for driving the gate lines GA1, GA2, GA3, and GA4 is output from the gate drive circuit 110. By inputting a signal to the source drive circuit 120, the source drive circuit 120 inputs a data voltage to the data lines, thereby charging the subpixel SPX and inputting the data voltage corresponding to the subpixel SPX to realize the screen display function. For example, two source drive circuits 120 may be provided, with one source drive circuit 120 connected to half of the data lines and the other source drive circuit 120 connected to the remaining half of the data lines. Of course, one, three, four, or more source drive circuits 120 may be provided, and the number can be designed and determined according to the actual application requirements, but is not limited thereto.

[0034] For example, each pixel unit contains multiple subpixels (SPX). For instance, a pixel unit may contain red, green, and blue subpixels, and a color display can be achieved by mixing red, green, and blue. Alternatively, a pixel unit may contain red, green, blue, and white subpixels, and a color display can be achieved by mixing red, green, blue, and white. Of course, in actual applications, the emission colors of the subpixels in a pixel unit can be designed and determined according to the specific application environment, and are not limited thereto.

[0035] The display panel in the embodiments of the present invention may be a liquid crystal display panel, an OLED display panel, or the like, but is not limited thereto.

[0036] In some examples, the gate drive circuit may include multiple shift registers, for example, shift registers from the 1st to the Nth stage: SR(1), SR(2)...SR(n-1), SR(n)...SR(N-1), SR(N) (a total of N shift registers, 1 ≤ n ≤ N, where n is an integer). Multiple shift registers are divided into multiple register groups. Here, shift registers within the same register group can be cascaded, and different register groups are connected to different frame start signal terminals.

[0037] For example, a shift register within a gate drive circuit can be divided into two register groups. Figure 2, for instance, shows the shift registers SR(1) to SR(24) from the 1st to the 24th stage as an example.

Here, the input signal terminal IP of the 1st stage shift register SR(1), the input signal terminal IP of the 3rd stage shift register SR(3), and the input signal terminal IP of the 5th stage shift register SR(5) are all electrically connected to the frame start signal terminal STV_A. In addition, the output signal terminal GO of the 1st stage shift register SR(1) is electrically connected to the input signal terminal IP of the 7th stage shift register SR(7). The output signal terminal GO of the 3rd stage shift register SR(3) is electrically connected to the input signal terminal IP of the 9th stage shift register SR(9).

[0039] The output signal terminal GO of the 15th stage shift register SR(15) is electrically connected to the input signal terminal IP of the 21st stage shift register SR(21). The output signal terminal GO of the 17th stage shift register SR(17) is electrically connected to the input signal terminal IP of the 23rd stage shift register SR(23). Furthermore, the output signal terminal GO of the 9th stage shift register SR(9) is electrically connected to the reset signal terminal RE of the 1st stage shift register SR(1). The output signal terminal GO of the 11th stage shift register SR(11) is electrically connected to the reset signal terminal RE of the 3rd stage shift register SR(3).

[0040] The output signal terminal GO of the 21st stage shift register SR(21) is electrically connected to the reset signal terminal RE of the 13th stage shift register SR(13). The output signal terminal GO of the 23rd stage shift register SR(23) is electrically connected to the reset signal terminal RE of the 15th stage shift register SR(15).

[0041] As shown in Figures 2 and 3b, of these two register groups, the second register group X2 includes even-numbered shift registers, namely the 2nd stage shift register SR(2), the 4th stage shift register SR(4), the 6th stage shift register SR(6), ... the 20th stage shift register SR(20), the 22nd stage shift register SR(22), and the 24th stage shift register SR(24). Furthermore, the even-numbered shift registers are electrically connected to the even-numbered gate lines. Here, the input signal terminal IP of the 2nd stage shift register SR(2), the input signal terminal IP of the 4th stage shift register SR(4), and the input signal terminal IP of the 6th stage shift register SR(6) are all electrically connected to the frame start signal terminal STV_B. Also, the output signal terminal GO of the 2nd stage shift register SR(2) is electrically connected to the input signal terminal IP of the 8th stage shift register SR(8). The output signal terminal GO of the 4th stage shift register SR(4) is electrically connected to the input signal terminal IP of the 10th stage shift register SR(10). The output signal terminal GO of the 16th stage shift register SR(16) is electrically connected to the input signal terminal IP of the 22nd stage shift register SR(22). The output signal terminal GO of the 18th stage shift register SR(18) is electrically connected to the input signal terminal IP of the 24th stage shift register SR(24). Furthermore, the output signal terminal GO of the 10th stage shift register SR(10) is electrically connected to the reset signal terminal RE of the 2nd stage shift register SR(2). The output signal terminal GO of the 12th stage shift register SR(12) is electrically connected to the reset signal terminal RE of the 4th stage shift register SR(4).

[0042] The output signal terminal GO of the 22nd stage shift register SR(22) is electrically connected to the reset signal terminal RE of the 14th stage shift register SR(14). The output signal terminal GO of the 24th stage shift register SR(24) is electrically connected to the reset signal terminal RE of the 16th stage shift register SR(16).

[0043] Figure 4 shows the signal timing diagram corresponding to the gate drive circuit shown in Figure 2. Here, stv_a represents the signal at the frame start signal terminal STV_A, stv_b represents the signal at the frame start signal terminal STV_B, ck1 represents the clock signal transmitted on the clock signal line CK1, ck2 represents the clock signal transmitted on the clock signal line CK2, ck3 represents the clock signal transmitted on the clock signal line CK3, ck4 represents the clock signal transmitted on the clock signal line CK4, ck5 represents the clock signal transmitted on the clock signal line CK5, ck6 represents the clock signal transmitted on the clock signal line CK6, ck7 represents the clock signal transmitted on the clock signal line CK7, ck8 represents the clock signal transmitted on the clock signal line CK8, ck9 represents the clock signal transmitted on the clock signal line CK9, ck10 represents the clock signal transmitted on the clock signal line CK10, and ck11 represents the clock signal transmitted on the clock signal line CK11. ck12 represents the clock signal transmitted on the clock signal line CK2.

Signal go2 represents the gate drive signal output by GO at the output signal terminal of the second stage shift register SR(2). Signal go3 represents the gate drive signal output by GO at the output signal terminal of the third stage shift register SR(3).

[0044] Signal go24 represents the gate drive signal output by the GO terminal of the 24th stage shift register SR(24).

[0045] In this embodiment of the present invention, the shift register in the gate drive circuit is described in an example where it is divided into two register groups. In actual applications, the shift register in the gate drive circuit can be divided into three, four, or more register groups, but is not limited to this.

[0046] In actual application examples, the frame start signal terminal is electrically connected to the input signal terminal IP of the shift register via a signal lead line. However, currently, signal lead lines corresponding to the start signal terminals of the same frame are located in the same area, and no other signal lines are provided between signal lead lines corresponding to the start signal terminals of the same frame. This is not helpful for wiring the signal lead lines.

[0047] In embodiments of the present invention, multiple signal pull lines are also provided in the non-display area. The multiple signal pull lines are divided into multiple line groups, and one line group is electrically connected to one register group. Between two signal pull lines of the same line group, there are signal pull lines from other line groups. These multiple signal pull lines may, for example, be signal lines that electrically connect the frame start signal terminal and the input signal terminal IP of a shift register. Alternatively, these multiple signal pull lines may be clock signal lines, or other functional signal lines.

[0048] For example, if these multiple signal leads are signal lines that electrically connect the frame start signal terminal and the input signal terminal IP of a shift register, in an embodiment of the present invention, as shown in conjunction with Figures 2, 3a, 5a, and 5b, the multiple signal leads 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, and 110-3, and the first line group is connected to the frame start signal terminal STV_A of the first register group X1. Here, signal lead 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), signal lead 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 signal lead 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).

[0049] Furthermore, as shown in Figures 2, 3b, 5a, 5b, and 6, the second of the two line groups includes signal pull-in lines 120-1, 120-2, and 120-3. The second line group is also connected to the frame start signal terminal STV_B of the second register group X2. Here, signal pull-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). Signal pull-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). Signal pull-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).

[0050] As shown in Figures 5a and 5b, the signal leads of the first and second wire groups are arranged alternately. For example, signal leads 120-3, 110-3, 120-2, 110-2, 120-1, and 110-1 are arranged sequentially 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, and the transistor has a gate electrode, an active layer, a source and a drain electrode. Here, the gate electrode and the gate line are located in the same layer and are made of the same material, the source and drain electrodes and the data line are located in the same layer and are made of the same material, and the active layer is located between the layer where the gate line is located and the layer where the data line is located. Furthermore, a gate insulating layer is provided between the layer where the gate line is located and the layer where the active layer is located, and an interlayer insulating layer (e.g., PVX) is provided between the layer where the active layer is located and the layer where the data line is located.

[0052] In embodiments of the present invention, the signal lead wire may be provided in the same layer and material as the gate wire. In this way, when preparing the gate wire, only the pattern of the original mask needs to be changed when forming the gate wire pattern, and the gate wire pattern and the signal lead wire pattern can be formed simultaneously. The preparation process can be simplified in a single patterning process without adding a separate process for preparing the signal lead wire, saving production costs and improving production efficiency.

[0053] In embodiments of the present invention, the display panel further comprises a plurality of signal inputs and a plurality of bridges, wherein the signal inputs and signal lead lines are located on the same layer. One of the plurality of line groups is electrically connected to a signal input in the plurality of signal inputs. In addition, one of the plurality of line groups is directly electrically connected to a corresponding signal input, and the remaining line groups are electrically connected to the corresponding signal inputs via the bridges. For example, if these plurality of signal lead lines are signal lines that electrically connect the frame start signal terminal and the input signal terminal IP of a shift register, then in embodiments of the present invention, the plurality of signal inputs includes a first signal input 210 and a second signal input 220. As shown in Figures 2, 3a, 5a to 6, the first signal input 210 is an integral structure formed of the same film layer material, and the signal lead lines 110-1, 110-2, and 110-3 of the first line group can be directly electrically connected to the first signal input 210. In other words, the signal lead lines 110-1, 110-2, and 110-3 of the first line group are an integrated structure formed from the same film layer as the first signal introduction section 210. The signal lead lines 120-1, 120-2, and 120-3 of the second line group are electrically connected to the second signal introduction section 220 via the bridge section 300. That is, there is a gap between the signal lead lines 120-1, 120-2, and 120-3 of the second line group and the second signal introduction section 220.

[0054] Specifically, the first ends of the signal lead lines 110-1, 110-2, and 110-3 of the first line group can be directly electrically connected to the first signal input unit 210. The second ends of the signal lead lines 110-1, 110-2, and 110-3 of the first line group are each electrically connected to the input signal terminals IP of the shift registers of the first register group. In this way, the signal stv_a input by the first signal input unit 210 is directly input to the input signal terminal IP of the second stage shift register SR(1) via the signal lead line 110-1. The signal stv_a input from the first signal input unit 210 is then directly input to the input signal terminal IP of the third stage shift register SR(3) via the signal lead line 110-2. The signal stv_a input from the first signal input unit 210 is then directly input to the input signal terminal IP of the fifth stage shift register SR(5) via the signal lead line 110-3.

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

[0056] In embodiments of the present invention, the bridge section and the signal introduction section are located on different layers. For example, the bridge section and data lines may be arranged on the same layer using the same material. This allows the data line pattern and the bridge section pattern to be formed simultaneously simply by changing the patterning pattern of the original mask when preparing the data lines. The bridge section does not need to be prepared separately, simplifying the preparation process with a single patterning process, saving production costs, and improving production efficiency.

[0057] In embodiments of the present invention, as shown in Figures 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. The display panel may also 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 on different layers, while the second bridge connection section 420 and the first bridge connection section 410 are located on the same layer. For example, if 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 on the same layer and made of the same material as the pixel electrodes.

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

[0059] For example, the first turn via hole GZ1 penetrates the interlayer insulation layer. The second turn via hole GZ2 penetrates the gate insulation layer and the interlayer insulation layer.

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

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

[0062] In embodiments of the present invention, the shape of the third subbridge portion may be non-linear. For example, as shown in Figure 5c, the shape of the third subbridge portion (331, 332, 333) may be a broken line shape. Alternatively, the third subbridge portion (331, 332, 333) may be a broken line shape consisting of three straight lines, having two bending angles, the bending angles of which may be obtuse. Or, the shape of the third subbridge portion may be curved. Furthermore, the third subbridge portion may be formed by an arc-shaped curve. Of course, in actual applications, the shape of the third subbridge portion can be determined according to the requirements of the actual application and is not limited thereto.

[0063] In embodiments of the present invention, as shown in Figures 5a, 5c, and 6, a plurality of second subbridge sections may be arranged at intervals from one another. For example, there may be gaps between the second subbridge sections 321, 322, and 323, and the orthographic projection of the plurality of second subbridge sections on the base substrate may not overlap with the orthographic projection of the signal lead lines of the first line group on the base substrate. This reduces the overlapping area between the second subbridge sections and the signal lead lines of the first line group, thereby reducing signal interference.

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

[0065] The second subbridge connection section 422 is electrically connected to the second subbridge section 322 via the third turn via hole GZ3, and the second subbridge connection section 422 is electrically connected to the signal lead line 120-2 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 fourth stage shift register SR(4) sequentially via the first bridge connection section 410, the first bridge section 310, the second subbridge section 322, the second subbridge connection section 422, and the signal lead line 120-2.

[0066] The second subbridge connection section 423 is electrically connected to the second subbridge section 323 via the third turn via hole GZ3, and the second subbridge connection section 423 is electrically connected to the signal lead line 120-3 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 sixth stage shift register SR(6) sequentially via the first bridge connection section 410, the first bridge section 310, the second subbridge section 323, the second subbridge connection section 423, and the signal lead line 120-3.

[0067] For example, the third turn via hole GZ3 penetrates the interlayer insulation layer. The fourth turn via hole GZ4 penetrates the gate insulation layer and the interlayer insulation layer.

[0068] In embodiments of the present invention, as shown in Figures 5a and 5d, gaps may be formed between the plurality of second subbridge connections, and the orthographic projection of the plurality of second subbridge connections on the base substrate does not overlap with the orthographic projection of the signal lead lines of the first line group on the base substrate. This reduces the overlapping area between the second subbridge connections and the signal lead lines of the first line group, thereby reducing signal interference.

[0069] For example, the total number of third turn via holes GZ3 and fourth turn via holes GZ4 corresponding to one second subbridge connection may be the same. For instance, the total number of third turn via holes GZ3 and fourth turn via holes GZ4 corresponding to one second subbridge connection may be one, two, three, etc. Alternatively, the total number of third turn via holes GZ3 and fourth turn via holes GZ4 corresponding to one second subbridge connection may be different. Of course, in actual applications, the total number of corresponding third turn via holes GZ3 and fourth turn via holes GZ4 can be designed and determined according to the needs of the actual application, and is not limited thereto.

[0070] As shown in Figures 7a to 8, an embodiment of the present invention provides schematic diagrams of other display panels with modified implementations from the above embodiment. Hereinafter, only the differences between this embodiment and the previously described embodiment will be explained, and similarities will be omitted.

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

[0072] Since the second signal introduction unit 220 is electrically connected to the signal lead line of the second line group via the bridge unit, a large resistance difference occurs between the signal path from the second signal introduction unit 220 to stv_b corresponding to the signal lead line of the second line group and the signal path from the first signal introduction unit 210 to stv_a corresponding to the signal lead line of the first line group. This results in a difference in delay when 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. As a result, the brightness of the corresponding subpixels differs, affecting the display effect. In embodiments of the present invention, the first signal introduction unit 210 is divided into a first sub-signal introduction unit 211 and a third sub-signal introduction unit 213, and the first sub-signal introduction unit 211 and the third sub-signal introduction unit 213 are electrically connected via a fifth bridge connection unit 450, thereby increasing the resistance in the current path from the first signal introduction unit 210 to the signal lead line of the first line group. This reduces the voltage difference between the stv_a signal path and the stv_b signal path, reducing the delay difference when signals stv_a and stv_b are input to the signal input terminal IP, and improving display.

[0073] For example, the ninth turn via hole GZ9 penetrates the gate insulation layer and the interlayer insulation layer. The tenth turn via hole GZ10 penetrates the gate insulation layer and the interlayer insulation layer.

[0074] Exemplary, in embodiments of the present invention, as shown in Figures 7a to 8, the first signal introduction unit 210 may include one first sub-signal introduction unit 211 and a third sub-signal introduction unit 213. The second signal introduction unit 220 includes one second sub-signal introduction unit 221, i.e., the second signal introduction unit 220 functions as a second sub-signal introduction unit, so the number of first sub-signal introduction units 211 and second sub-signal introduction units 211 are the same. Here, the third sub-signal introduction unit 213 is directly electrically connected to the first end of each signal drop-in line 110-1, 110-2 and 110-3 in the first line group. Furthermore, the first end of the fifth bridge connection 450 is electrically connected to the first sub-signal input via the ninth turn via hole GZ9, and the second end of the fifth bridge connection 450 is electrically connected to the third sub-signal input 213 via the tenth turn via hole GZ10. In actual applications, the first sub-signal input 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 corresponding signal input terminal IP of the shift register sequentially via the first sub-signal input, the fifth bridge connection 450, the third sub-signal input 213, and the respective signal leads 110-1, 110-2, and 110-3 in the first line group.

[0075] Exemplary, in embodiments of the present invention, as shown in Figures 7a to 8, the total number of ninth turn via holes GZ9 and the total number of second turn via holes GZ2 may be the same. For example, the total number of ninth turn via holes GZ9 may be set to 12, 8, 10, etc. In actual applications, the total number of ninth turn via holes GZ9 and the total number of second turn via holes GZ2 may also be different. Of course, the total number of ninth turn via holes GZ9 and the total number of second turn via holes GZ2 can be designed and determined according to the needs of the actual application, and are not limited thereto.

[0076] Exemplary, in embodiments of the present invention, as shown in Figures 7a to 8, the total number of the 10th turn via holes GZ10 and the total number of the 1st turn via holes GZ1 may be the same. For example, the total number of the 10th turn via holes GZ10 and the total number of the 1st turn via holes GZ1 may be set to 12, 8, 10, etc. In actual applications, the total number of the 10th turn via holes GZ10 and the total number of the 1st turn via holes GZ1 may also be different. Of course, the total number of the 10th turn via holes GZ10 and the total number of the 1st turn via holes GZ1 can be designed and determined according to the needs of the actual application, and are not limited thereto.

[0077] As shown in Figures 9a to 10, embodiments of the present invention provide further schematic diagrams of the structure of the display panel. Hereinafter, only the differences between these embodiments and the previously described embodiments will be explained, and similarities will be omitted.

[0078] In embodiments of the present invention, as shown in Figures 9a to 10, the signal lead line of the first line group includes one first signal lead segment and one second signal lead segment. The display panel further includes a plurality of fourth bridge connections. Here, the fourth bridge connections and the first bridge connections 410 are located on the same layer, and here, in the same signal lead line, the first signal lead segment and the second signal lead segment are electrically connected via the fourth bridge connections. Exemplarily, the plurality of fourth bridge connections may be spaced apart from each other. Furthermore, the orthographic projection of the fourth bridge connections on the base substrate does not overlap with the orthographic projection of the signal lead line of the first line group, the fourth bridge connections, and the bridges on the base substrate. This further reduces signal interference.

[0079] Exemplary, in embodiments of the present invention, as shown in Figures 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 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 connector 440-1. In 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 connector 440-2. In 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 connector 440-3. This reduces the resistance difference between the signal lead lines of the first line group and the signal lead lines of the second line group, further reducing the delay of signals stv_a and stv_b and further improving the display effect.

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

[0081] For example, the fifth turn via hole GZ5 penetrates the gate insulation layer and the interlayer insulation layer. The sixth turn via hole GZ6 penetrates the gate insulation layer and the interlayer insulation layer.

[0082] Exemplary, in embodiments of the present invention, as shown in Figures 9a to 10, the second ends of each first signal lead segment within a first line group are spaced apart from each other. Furthermore, gaps are provided between the second ends of each first signal lead segment within a first line group. For example, the orthographic projection of the second ends of the first signal lead segments within a first line group on the base substrate does not overlap with the orthographic projection of each signal lead line within a second line group on the base substrate.

[0083] Exemplary, in embodiments of the present invention, if the signal lead line of the first line group includes a first signal lead segment and one second signal lead segment, the total number of fifth turn via holes GZ5 corresponding to one fourth bridge connection and the total number of third turn via holes GZ3 corresponding to one second bridge connection 420 may be the same. For example, the total number of fifth turn via holes GZ5 corresponding to one fourth bridge connection and the total number of third turn via holes GZ3 corresponding to one second bridge connection 420 may both be 2, 3, 1, or other numbers. Alternatively, the total number of fifth turn via holes GZ5 corresponding to one fourth bridge connection and the total number of third turn via holes GZ3 corresponding to one second bridge connection 420 may be different. Of course, in actual applications, the total number of fifth turn via holes GZ5 corresponding to one fourth bridge connection and the total number of third turn via holes GZ3 corresponding to one second bridge connection 420 can be designed and determined according to the needs of the actual application, and are not limited thereto.

[0084] Exemplary, in embodiments of the present invention, if the signal lead line of the first line group includes one first signal lead segment and one second signal lead segment, the total number of sixth turn via holes GZ6 corresponding to one fourth bridge connection and the total number of fourth turn via holes GZ4 corresponding to one second bridge connection 420 may be the same. For example, the total number of sixth turn via holes GZ6 corresponding to one fourth bridge connection and the total number of fourth turn via holes GZ4 corresponding to one second bridge connection 420 may both be 2, 3, 1, or other numbers. Alternatively, the total number of sixth turn via holes GZ6 corresponding to one fourth bridge connection and the total number of fourth turn via holes GZ4 corresponding to one second bridge connection 420 may be different. Of course, in actual applications, the total number of sixth turn via holes GZ6 corresponding to one fourth bridge connection and the total number of fourth turn via holes GZ4 corresponding to one second bridge connection 420 can be designed and determined according to the needs of the actual application, and are not limited thereto.

[0085] An embodiment of the present invention provides a further schematic diagram of the structure of the display panel, as shown in Figures 11a to 11d. Hereinafter, only the differences between this embodiment and the previously described embodiment will be explained, and similarities will be omitted.

[0086] In embodiments of the present invention, as shown in Figures 11a to 11d, the second ends of each first signal lead segment within the first line group are in contact with each other to form an integrated structure. That is, the orthographic projection on the base substrate of the integrated structure formed by the contact of the second ends of each first signal lead segment within the first line group has a region that overlaps with the orthographic projection on the base substrate of the signal lead lines of the second line group.

[0087] In embodiments of the present invention, as shown in Figures 11a to 11d, a plurality of second subbridge sections are in contact with each other to form an integrated structure. That is, the orthographic projection of the integrated structure formed by the plurality of second subbridge sections in contact with each other on the base substrate has a region superimposed with the orthographic projection of the signal lead lines of the first line group on the base substrate. For example, the three second subbridge connections included in the second bridge connection section 420 are in contact with each other to form an integrated structure.

[0088] An embodiment of the present invention provides a further schematic diagram of the structure of the display panel, as shown in Figures 12a and 12b. Hereinafter, only the differences between this embodiment and the previously described embodiment will be explained, and similarities will be omitted.

[0089] In embodiments of the present invention, the second signal introduction unit 220 includes at least one second sub-signal introduction unit, the first bridge connection unit 410 is electrically connected to each second sub-signal introduction unit via a second turn via hole 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 is the same as the total number of second sub-signal introduction units.

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

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

[0092] An embodiment of the present invention provides a further schematic diagram of the display panel, as shown in Figures 13a and 13b. Hereinafter, only the differences between this embodiment and the previously described embodiment will be explained, and similarities will be omitted.

[0093] In embodiments of the present invention, as shown in Figures 13a to 13c, the signal lead line of the first line group includes one first signal lead segment and at least two second signal lead segments. Here, in the same signal lead line, the first signal lead segment and the second signal lead segments are electrically connected via a fourth bridge connection. Adjacent second signal lead segments are electrically connected to the fourth bridge connection. Exemplarily, one second signal lead segment in an adjacent second signal lead segment is electrically connected to the first end of the corresponding fourth bridge connection via a seventh turn via hole GZ7, and the second end of the fourth bridge connection is electrically connected to another second signal lead segment via an eighth turn via hole GZ8.

[0094] For example, the seventh turn via hole GZ7 penetrates the gate insulation layer and the interlayer insulation layer. The eighth turn via hole GZ8 penetrates the gate insulation layer and the interlayer insulation layer.

[0095] In embodiments of the present invention, as shown in Figures 13a to 13c, the signal lead line of the second line group includes at least two third signal lead segments, and the display panel further includes a plurality of third bridge connections (e.g., 430-1, 430-2, 430-3). In the same signal lead line, two adjacent third signal lead segments are electrically connected via a third bridge connection, the first end of the third bridge connection is electrically connected to one third signal lead segment via a 13th turn via hole GZ13, and the second end of the third bridge connection is electrically connected to another third signal lead segment via a 14th turn via hole GZ14.

[0096] For example, the 13th turn via hole GZ13 penetrates the gate insulation layer and the interlayer insulation layer. The 14th turn via hole GZ14 penetrates the gate insulation layer and the interlayer insulation layer.

[0097] In the embodiments of the present invention, as shown in Figures 13a to 13c, the multiple fourth bridge connections are spaced apart from each other. That is, the orthographic projection of the fourth bridge connection on the base substrate and the orthographic projection of the signal lead lines of the second line group on the base substrate do not overlap.

[0098] In embodiments of the present invention, as shown in Figures 13a to 13c, the total number of fourth bridge connections corresponding to one signal lead line in a first line group is the same as the sum of the total number of third bridge connections and the total number of second bridge connections corresponding to one signal lead line in a second line group.

[0128] As shown in Figures 17a to 17d, embodiments of the present invention provide further schematic diagrams of the structure of the display panel. As shown in Figures 17a to 17d, only the differences between this embodiment and the previously described embodiment will be explained below, and similarities will be omitted from the explanation.

[0129] In embodiments of the present invention, as shown in Figures 17a to 17d, the display panel further includes a plurality of third auxiliary units (e.g., 530-1, 530-2, 530-3). The third auxiliary units and the first auxiliary unit 510 are located on the same layer as the bridge unit, and at least one third auxiliary unit is provided correspondingly to one signal lead line in a first line group, where in the same signal lead line, a first signal lead segment is electrically connected to a second signal lead segment via the corresponding third auxiliary unit. Exemplarily, the display panel further includes a plurality of sixth bridge adapters and a plurality of seventh bridge adapters, where at least one third auxiliary unit is provided correspondingly to at least one sixth bridge adapter and at least one seventh bridge adapter. The first end of the third auxiliary section is electrically connected to the corresponding sixth bridge adapter via the eleventh turn via hole GZ11, the sixth bridge adapter is electrically connected to the corresponding first signal lead segment via the twelfth turn via hole GZ12, the second end of the third auxiliary section is electrically connected to the corresponding seventh bridge adapter via the seventeenth turn via hole GZ17, and the seventh bridge adapter is electrically connected to the corresponding seventh bridge adapter via the eighteenth turn via hole GZ18.

[0130] For example, the 11th turn via hole GZ11 penetrates the interlayer insulation layer. The 12th turn via hole GZ12 penetrates the gate insulation layer and the interlayer insulation layer. The 17th turn via hole GZ17 penetrates the interlayer insulation layer. The 18th turn via hole GZ18 penetrates the gate insulation layer and the interlayer insulation layer.

[0131] Exemplary, as shown in Figures 17a to 17d, the signal lead line 110-1 is provided with a third auxiliary section 530-1, a sixth bridge adapter 460-1, and a seventh bridge adapter 470-1 in correspondence. The first signal lead segment 110-1a is electrically connected to the sixth bridge adapter 460-1 via a twelfth turn via hole GZ12, and the sixth bridge adapter 460-1 is electrically connected to the first end of the third auxiliary section 530-1 via an eleventh turn via hole GZ11. The second end of the third auxiliary section 530-1 is electrically connected to the seventh bridge adapter 470-1 via a seventeenth turn via hole GZ17, and the seventh bridge adapter 470-1 is electrically connected to the second signal lead segment 110-1b via an eighteenth turn via hole GZ18. This further reduces the difference between the resistance of the signal lead wires in the first wire group and the resistance of the signal lead wires in the second wire group. The rest is the same, so we will not repeat it here.

[0132] As shown in Figures 18a to 19, embodiments of the present invention provide further schematic diagrams of the structure of the display panel. Hereinafter, only the differences between these embodiments and the previously described embodiments will be explained, and similarities will be omitted from the explanation.

[0133] In embodiments of the present invention, as shown in Figures 18a to 19, the bridge section includes a fourth bridge section 340, a sixth bridge section, and a fifth bridge section connected between the fourth bridge section 340 and the sixth bridge section. Here, the fourth bridge section 340 and the second signal introduction section 220 are electrically connected via a first conductive via hole GK1, and the sixth bridge section and the signal lead line of the second line group are electrically connected via a second conductive via hole GK2. Exemplarily, the fifth bridge section includes a plurality of fifth subbridge sections (351, 352, 353, etc.) spaced apart from each other, the sixth bridge section includes a plurality of sixth subbridge sections (361, 362, 363, etc.) spaced apart from each other, and the fourth bridge section 340 is electrically connected to one signal lead line in the second line group via at least one fifth subbridge section and at least one sixth subbridge section.

[0134] Exemplary, the second signal introduction section 220 is electrically connected to the fourth bridge section 340 via the first conductive via hole GK1, the sixth subbridge section 361 is directly electrically connected to the fifth subbridge section 351, and the fifth subbridge section 351 is electrically connected to the signal lead line 120-1 via the second conductive via hole GK2. The sixth subbridge section 362 is directly electrically connected to the fifth subbridge section 352, and the fifth subbridge section 352 is electrically connected to the signal lead line 120-2 via the second conductive via hole GK2. The sixth subbridge section 363 is directly electrically connected to the fifth subbridge section 353, and the fifth subbridge section 353 is electrically connected to the signal lead line 120-3 via the second conductive via hole GK2.

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

[0136] Because the second signal introduction unit 220 must pass through the bridge unit to electrically connect to the signal lead line of the second line group, there is a large difference in resistance between the signal path of stv_b corresponding to the signal lead line of the second line group from the second signal introduction unit 220 and the signal path of stv_a corresponding to the signal lead line of the first line group from the first signal introduction unit 210. This results in a difference in delay when signals stv_a and stv_b are input to the signal input terminal IP. Since the signals output from the output signal terminal GO of the first, third, and fifth stage shift registers are different from those of the second, fourth, and sixth stage shift registers, the brightness of the corresponding subpixels differs, affecting the display effect. In embodiments of the present invention, a first hollow region KB1 is provided in the first signal introduction section 210, and a first bonding via hole GH1 and a first bonding slit GF1 that penetrate the second signal introduction section 220 are provided in the first hollow region KB1. This increases the resistance of the first signal introduction section 210, reduces the voltage difference between the signal path of stv_a and the signal path of stv_b, reduces the difference in delay when signals stv_a and stv_b are input to the signal input terminal IP, and improves the display effect.

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

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

[0139] In embodiments of the present invention, as shown in Figures 18a to 19, the signal lead wires of the first wire group may include second hollow regions (KB-1, KB-2, KB-3, etc.). The second hollow region includes a second bonding via hole GH2 and a second bonding slit GF2. Here, the second bonding via hole GH2 passes through the signal lead wires of the first wire group. The second bonding slit GF2 also passes through the signal lead wires of the first wire group. This allows the resistance of the signal lead wires of the first wire group to be increased, and the difference between the resistance of the signal path for signal stv_a and the resistance of the signal path for signal stv_b to be reduced.

[0140] In embodiments of the present invention, as shown in Figures 18a to 19, the second hollow region (for example, KB-1, KB-2, KB-3) also includes a second bonding via hole GH2, where the second bonding via hole GH2 passes through the signal lead line of the first line group and is located on the side of the second bonding slit GF2 away from the first bonding via hole GH1.
