In order to reduce the number of driving chips, reduce the border, and lower costs, a gate driving circuit is used to replace the gate driving chip to drive the pixel circuit.

[0052] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0053] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", and "electrical connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0054] In order to illustrate the principle of the technical problem in the embodiments of the present application, some comparative display devices are provided. It can be understood that these comparative display devices cannot be regarded as the prior art in the embodiments of the present application. As Figure 1 shown, the comparative display device 1 includes a pixel circuit 11 and a gate circuit 12. The gate circuit 12 is respectively provided with a wiring area 121 and a transistor area 122. A signal wiring 121a is provided in the wiring area 121, and a thin film transistor 122a is provided in the transistor area 122. By extending the signal wiring 121a from the wiring area 121 into the transistor area 122 and connecting it to the corresponding transistor 122a, the normal operation of the gate circuit 12 is realized. However, since the signal wiring 121a is arranged on the same layer as the source and drain electrodes of the transistor, in order to avoid short circuits between the unconnected signal wiring and the source and drain electrodes of the transistor, the signal wiring needs to be spaced from the source and drain electrodes of the transistor, resulting in the need to separately set the wiring area 121 and the transistor area 122. The wiring area 121 needs to occupy a large space, and when the signal wiring 121a extends into the transistor area 122, each transistor needs to occupy more space to avoid the unconnected signal wiring 121a, resulting in a large space occupied by the gate circuit 12. Therefore, the current display device has the technical problem that the lateral space occupied by the thin film transistor setting area and the signal wiring area in the gate driving circuit is large, resulting in a large border of the display device.

[0055] The embodiments of the present application provide a display panel and a display device to solve the above technical problems.

[0056] Based on the problem that the wiring area and the transistor area in the comparative display device need to be separately set, resulting in a large space occupied by both the wiring area and the transistor area, the embodiments of the present application adjust aspects such as the setting position of the signal line, the setting film layer of the signal line, and the arrangement mode of the signal lines, and / or adjust aspects such as the setting position of the transistor, the arrangement mode of the transistors, and the design of the transistor structure, so as to reduce the occupied space of the gate driving circuit 22 and reduce the border of the display panel 2.

[0059] As Figure 2 shown, an embodiment of the present application provides a display panel 2, which includes a display area 201 and a non-display area 202. A plurality of pixels 23 are provided in the display area 201. The pixel 23 includes a light-emitting device LED and a pixel driving circuit 21 for driving the light-emitting device LED. A multi-stage gate driving circuit 22 is provided in the non-display area 202. The multi-stage gate driving circuit 22 can be arranged along the second direction Y. The gate driving circuit 22 outputs a scanning signal to the pixel driving circuit 21.

[0060] Specifically, as Figure 2 shown, the non-display area 202 can be disposed around the display area 201. However, the embodiments of the present application are not limited thereto. The non-display area 202 can be disposed on one side, both sides, or three sides of the display area 201, and the non-display area 202 can be bent to the back of the display area 201. The non-display area 202 can include an upper border area, a lower border area, a left border area, and a right border area. The gate driving circuit 22 can be disposed in the left border area and / or the right border area, and the gate driving circuit 22 can be disposed along the first direction X on one side or both sides of the display area 201.

[0061] As Figure 3 shown, as a specific structure of the display panel 2 in the embodiments of the present application, the display panel 2 includes a substrate 211, a light-shielding layer 212, a buffer layer 213, a semiconductor layer 214, a first gate insulating layer 215, an active layer 216, a second gate insulating layer 217, a first gate layer 218, a third gate insulating layer 232, a second gate layer 225, a first interlayer insulating layer 219, a first source-drain layer 221, a passivation layer 222, a first planarization layer 224, a second source-drain layer 223, a second planarization layer 226, a third planarization layer 227, a pixel electrode layer 228, a first pixel definition layer 229, a second pixel definition layer 231, a light-emitting functional layer, and a common electrode layer, which are sequentially disposed.

[0062] Specifically, the material of the semiconductor layer 214 includes an oxide semiconductor, specifically a metal oxide, and more specifically indium gallium zinc oxide.

[0063] Specifically, the material of the active layer 216 can include one of a silicon semiconductor and an oxide semiconductor, specifically low-temperature polycrystalline silicon or a metal oxide, specifically Ln-IZO (indium zinc oxide doped with lanthanide elements), IGZTO (indium gallium zinc tin oxide).

[0064] Specifically, as Figure 3 shown, Figure 3 shows that the display panel 2 includes a semiconductor layer 214 and an active layer 216. However, the embodiments of the present application are not limited thereto. The display panel 2 can include only one of the semiconductor layer 214 and the active layer 216.

[0065] Specifically, as Figure 3 shown, Figure 3 shows that the display panel includes two gate layers. However, the embodiments of the present application are not limited thereto. The display panel can include one gate layer or three gate layers.

[0066] Specifically, as Figure 3 shown, Figure 3It is shown in the figure that the display panel 2 includes a first source-drain layer 221 and a second source-drain layer 223. However, the embodiments of the present application are not limited thereto, and the display panel 2 may include a first source-drain layer 221, a second source-drain layer 223, and a third source-drain layer.

[0067] Specifically, as Figure 3 shown, Figure 3 It is shown in the figure that the light-shielding layer 212 is only disposed in the display area 201. However, the embodiments of the present application are not limited thereto, and the light-shielding layer 212 may be disposed in the non-display area 202.

[0068] Specifically, as Figure 3 shown, Figure 3 It is shown in the figure that the transistors in the display area 201 all use the semiconductor layer 214 as the active part, and the transistors in the non-display area 202 all use the active layer 216 as the active part. However, the embodiments of the present application are not limited thereto. Some transistors in the display area 201 may use the semiconductor layer 214 as the active part, and some transistors in the display area 201 may use the active layer 216 as the active part. Similarly, some transistors in the non-display area 202 may use the semiconductor layer 214 as the active part, and some transistors in the non-display area 202 may use the active layer 216 as the active part.

[0069] Specifically, as Figure 3 shown, Figure 3 Taking the display panel 2 as an organic light-emitting diode display panel 2 as an example for illustration. However, the embodiments of the present application are not limited thereto, and the display panel 2 may be a liquid crystal display panel 2 or other types of display panels 2.

[0070] Specifically, as Figures 5 to 7 shown, each stage of the gate driving circuit 22 includes a first type of gate circuit 22a, a second type of gate circuit 22b, and a third type of gate circuit 22c.

[0071] As Figures 2 to 41As shown in the figure, an embodiment of the present application provides a display panel 2, which includes multiple rows of pixels 23 and a multi-stage gate driving circuit 22. The pixel 23 includes a light-emitting device LED and a pixel driving circuit 21. The multi-stage gate driving circuit 22 is electrically connected to the corresponding pixel driving circuit 21 respectively. Each stage of the gate driving circuit 22 includes a first type of gate circuit 22a, a second type of gate circuit 22b, and a third type of gate circuit 22c arranged along the first direction X. The first type of gate circuit 22a is electrically connected to at least a first clock signal line CKA, a second clock signal line CKB, a first high-potential signal line VGH1, a first low-potential signal line VGL1, a second low-potential signal line VGL2, a first reset control line VST1, and a low-frequency signal line LC. The second type of gate circuit 22b is electrically connected to at least the first high-potential signal line VGH1, the second low-potential signal line VGL2, a third clock signal line CKC of the display panel, and a second reset control line VST2 of the display panel. The third type of gate circuit 22c is electrically connected to at least the first high-potential signal line VGH1, a second high-potential signal line VGH2, the second low-potential signal line VGL2, and a third low-potential signal line VGL3.

[0072] Wherein, the display panel 2 further includes a substrate 211, an active layer 216, a first gate layer 218, a first source-drain layer 221, and a second source-drain layer 223 arranged in sequence. At least one of the first clock signal line CKA, the second clock signal line CKB, the third clock signal line CKC, the first high-potential signal line VGH1, the second high-potential signal line VGH2, the first low-potential signal line VGL1, the second low-potential signal line VGL2, the third low-potential signal line VGL3, the first reset control line VST1, the second reset control line VST2, and the low-frequency signal line LC is disposed on the second source-drain layer 223.

[0073] An embodiment of the present application provides a display panel 2. By providing the first source-drain layer 221 and the second source-drain layer 223, at least one of the first clock signal line CKA, the second clock signal line CKB, the third clock signal line CKC, the first high-potential signal line VGH1, the second high-potential signal line VGH2, the first low-potential signal line VGL1, the second low-potential signal line VGL2, the third low-potential signal line VGL3, the first reset control line VST1, the second reset control line VST2, and the low-frequency signal line LC is disposed on the second source-drain layer 223, the number of traces in the first source-drain layer can be reduced, thereby reducing the lateral space occupied by the first source-drain layer, further reducing the space occupied by the gate driving circuit, and reducing the border of the display panel.

[0074] Specifically, compared with the comparative display device where the source, drain, and each signal trace of the transistor are formed in the first source-drain layer, and each signal trace, the source and drain of the transistor all need to occupy the lateral space of the first source-drain layer, and each signal trace needs to wind around when connected to the source and drain of the transistor, further occupying the lateral space, resulting in a larger width of the first source-drain layer, and further resulting in a larger border of the gate driving circuit. In the embodiment of the present application, by arranging at least part of the signal lines in the second source-drain layer, the number of traces in the first source-drain layer is reduced, the lateral space occupied by the first source-drain layer is reduced, and the signal lines in the second source-drain layer can overlap with the traces in the first source-drain layer or the source and drain of the transistor in the thickness direction, reducing the occupied space of the connection lines, reducing the space occupied by the gate driving circuit, and reducing the border of the display panel.

[0075] In some embodiments, as Figures 8 to 23 shown, at least one of the first reset control line VST1, the low-frequency signal line LC, the first clock signal line CKA, the second clock signal line CKB, the first low-potential signal line VGL1, and the second low-potential signal line VGL2 is arranged in the second source-drain layer 223. By arranging at least one of the first reset control line VST1, the low-frequency signal line LC, the first clock signal line CKA, the second clock signal line CKB, the first low-potential signal line VGL1, and the second low-potential signal line VGL2 in the second source-drain layer 223, the lateral space occupied by the signal lines electrically connected to the first type of gate circuit can be reduced, and the border of the display panel can be reduced.

[0076] Specifically, compared with the comparative display device where each signal line connected to the first type of gate circuit 22a needs to be arranged in the first source-drain layer and needs to extend from the trace area to the transistor area, resulting in a larger occupied lateral space, in the embodiment of the present application, by arranging the signal lines connected to the first type of gate circuit 22a in the second source-drain layer, the width of the first source-drain layer is reduced, and the distance between the signal lines arranged in the second source-drain layer and the connected transistors can be shortened, thereby reducing the occupied space of the connection lines, reducing the space occupied by the gate driving circuit, and reducing the border of the display panel.

[0077] In some embodiments, as Figures 8 to 23 shown, the first reset control line VST1 is arranged in the second source-drain layer 223. By arranging the first reset control line VST1 in the second source-drain layer 223, the first reset control line VST1 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0078] In some embodiments, as Figure 5 , Figures 8 to 23 , Figure 24 to Figure 29 As shown in Figure 24 to Figure 29 , the first type of gate circuit 22a includes a first pull-up control module 311, and there is a gap between the projection of the first reset control line VST1 on the substrate 211 and the projection of the first pull-up control module 311 on the substrate 211. By making there be a gap between the projection of the first reset control line VST1 on the substrate and the projection of the first pull-up control module 311 on the substrate 211, the first reset control line VST1 can be prevented from affecting the signal lines and transistors in the first type of gate circuit 22a, and space can be reserved for other signal lines.

[0079] Specifically, the above embodiment is described by taking the example that there is a gap between the projection of the first reset control line VST1 on the substrate 211 and the projection of the first pull-up control module 311 on the substrate 211, but the embodiments of the present application are not limited thereto. The projection of the first reset control line VST1 on the substrate 211 may overlap with each module in the first type of gate circuit 22a. For example, the projection of the first reset control line VST1 on the substrate 211 overlaps with the projection of the first pull-up control module 311 on the substrate 211, or the projection of the first reset control line VST1 on the substrate 211 overlaps with the projection of the first reset module 317 on the substrate 211.

[0080] In some embodiments, as Figure 5 , Figures 8 to 23 , Figure 24 to Figure 29 shown, the first type of gate circuit 22a includes a first reset module 317, and the first reset module 317 is electrically connected to the first reset control line VST1;

[0081] Among them, the first source-drain layer 221 includes a first source connection line LD1. There is a gap between the projection of the first reset control line VST1 on the substrate 211 and the projection of the first reset module 317 on the substrate 211, and the first reset control line VST1 is connected to the first reset module 317 through the first source connection line LD1. By making there be a gap between the projection of the first reset control line VST1 on the substrate 211 and the projection of the first reset module 317 on the substrate 211, the first reset control line VST1 can be prevented from affecting the signal lines and transistors in the first type of gate circuit 22a, and space can be reserved for other signal lines. Moreover, since the first reset control line VST1 is connected to the first reset module 317 through the first source connection line LD1, normal connection between the first reset control line VST1 and the first reset module can be achieved.

[0082] In some embodiments, as Figures 8 to 23As shown, the low-frequency signal line LC is disposed on the second source-drain layer 223. By disposing the low-frequency signal line LC on the second source-drain layer 223, the low-frequency signal line LC does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0083] In some embodiments, such as Figure 5 , Figures 8 to 23 , Figure 24 to Figure 29 As shown, the first type of gate circuit 22a includes a first inverter module 315, and the low-frequency signal line LC is electrically connected to the first inverter module 315; the projection of the low-frequency signal line LC on the substrate 211 overlaps with the projection of the first inverter module 315 on the substrate 211. By making the projection of the low-frequency signal line LC on the substrate 211 overlap with the projection of the first inverter module 315 on the substrate 211, the signals of the signal lines and transistors in the first type of gate circuit 22a are not affected, and space can be reserved for other signal lines.

[0084] In some embodiments, such as Figures 8 to 23 As shown, the first clock signal line CKA is disposed on the second source-drain layer 223. By disposing the first clock signal line CKA on the second source-drain layer 223, the first clock signal line CKA does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0085] Specifically, it can be understood that each clock signal line in the display panel 2 will include multiple clock lines. The multiple clock lines will occupy a large space in the first source-drain layer, and setting the multiple clock lines outside the transistor region and connecting them to the transistors by extending into the transistor region will further occupy space, resulting in a large lateral occupied space of the gate driving circuit 22 and a large border of the display panel 2. In the embodiment of the present application, by disposing the first clock signal line CKA on the second source-drain layer 223, the lateral space occupied by the clock signal line can be reduced, and the border of the display panel 2 can be reduced.

[0086] In some embodiments, such as Figure 5 , Figures 8 to 23 , Figure 24 to Figure 29As shown, the first type of gate circuit 22a includes a first pull-up control module 311. The projection of the first clock signal line CKA on the substrate 211 overlaps with the projection of the first pull-up control module 311 on the substrate 211. By making the projection of the first clock signal line CKA on the substrate 211 overlap with the projection of the first pull-up control module 311 on the substrate 211, the first clock signal line does not need to occupy extra space, reducing the space occupied by the gate driving circuit and reducing the border of the display panel 2.

[0087] Specifically, as Figures 8 to 23 , Figure 24 to Figure 29 shown, the first clock signal line CKA may include a first clock first line CKA1, a first clock second line CKA2, a first clock third line CKA3, and a first clock fourth line CKA4. Every four levels of the first type of gate circuit 22a are connected to these four first clock signal lines CKA in a cycle. For example, the first-level to fourth-level first type of gate circuits 22a are respectively connected to the first clock first line CKA1, the first clock second line CKA2, the first clock third line CKA3, and the first clock fourth line CKA4. The fifth-level to eighth-level first type of gate circuits 22a are respectively connected to the first clock first line CKA1, the first clock second line CKA2, the first clock third line CKA3, and the first clock fourth line CKA4. Similarly, the clock signal lines connected to other levels of the first type of gate circuit 22a can be determined.

[0088] Specifically, the first clock fourth line CKA4, the first clock third line CKA3, the first clock second line CKA2, and the first clock first line CKA1 are arranged in sequence along the first direction.

[0089] Specifically, the above embodiments are described by taking the first clock signal line CKA including four clock lines as an example, but the embodiments of the present application are not limited thereto. The first clock signal line CKA may include other numbers of clock lines, for example, it may include 8 clock lines.

[0090] Specifically, among every four levels of the first type of gate circuit 22a, the positions of the connections between each level of the first type of gate circuit 22a and the first clock signal line CKA are different.

[0091] In some embodiments, as Figures 8 to 23 shown, the second clock signal line CKB is disposed on the second source-drain layer 223. By making the second clock signal line CKB disposed on the second source-drain layer 223, the second clock signal line CKB does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0092] Specifically, it can be understood that each clock signal line in the display panel 2 includes multiple clock lines. The multiple clock lines will occupy a relatively large space in the first source-drain layer. Moreover, the multiple clock lines are arranged outside the transistor region and extend into the transistor region to be connected to the transistor, which will further occupy space, resulting in a relatively large lateral occupied space of the gate driving circuit 22 and a relatively large border of the display panel 2. In the embodiment of the present application, by disposing the second clock signal line CKB in the second source-drain layer 223, the lateral space occupied by the clock signal line can be reduced, and the border of the display panel 2 can be reduced.

[0093] In some embodiments, as Figure 5 , Figures 8 to 23 , Figure 24 to Figure 29 shown, the first type of gate circuit 22a includes a first pull-up module 312, and the projection of the second clock signal line CKB on the substrate 211 overlaps with the projection of the first pull-up module 312 on the substrate 211. By making the projection of the second clock signal line CKB on the substrate 211 overlap with the projection of the first pull-up module 312 on the substrate 211, the second clock signal line CKB does not need to occupy additional space, and the second clock signal line is convenient to be connected to the first pull-up module 312, reducing the occupied space of the connection line, reducing the occupied space of the gate driving circuit, and reducing the border of the display panel 2.

[0094] Specifically, the second clock signal line CKB includes a first group of sub-lines CKBi and a second group of sub-lines CKBj, and the projection of the first group of sub-lines CKBi on the substrate 211 overlaps with the projection of the first pull-up module 312 on the substrate 211.

[0095] Specifically, the second clock signal line CKB may include a second clock first line CKB1, a second clock second line CKB2, a second clock third line CKB3, a second clock fourth line CKB4, a second clock fifth line CKB5, a second clock sixth line CKB6, a second clock seventh line CKB7, and a second clock eighth line CKB8. The second clock first line CKB1, the second clock third line CKB3, the second clock fifth line CKB5, and the second clock seventh line CKB7 in the second clock signal line CKB serve as the first group of sub-lines CKBi, and the second clock second line CKB2, the second clock fourth line CKB4, the second clock sixth line CKB6, and the second clock eighth line CKB8 serve as the second group of sub-lines CKBj. The second pull-up transistors T22j of every four levels of the first type of gate circuits 22a are connected to the first group of sub-lines CKBi in a cyclic manner, and the third pull-up transistors T23j of every four levels of the first type of gate circuits 22a are connected to the second group of sub-lines CKBj in a cyclic manner. For example, the second pull-up transistors T22j of the first to fourth levels of the first type of gate circuits 22a are respectively connected to the second clock first line CKB1, the second clock third line CKB3, the second clock fifth line CKB5, and the second clock seventh line CKB7, and the third pull-up transistors T23j of the first to fourth levels of the first type of gate circuits 22a are respectively connected to the second clock second line CKB2, the second clock fourth line CKB4, the second clock sixth line CKB6, and the second clock eighth line CKB8; the second pull-up transistors T22j of the fifth to eighth levels of the first type of gate circuits 22a are respectively connected to the second clock first line CKB1, the second clock third line CKB3, the second clock fifth line CKB5, and the second clock seventh line CKB7, and the third pull-up transistors T23j of the fifth to eighth levels of the first type of gate circuits 22a are respectively connected to the second clock second line CKB2, the second clock fourth line CKB4, the second clock sixth line CKB6, and the second clock eighth line CKB8; similarly, the clock signal lines connected to the first type of gate circuits 22a at other levels can be determined.

[0096] Specifically, the second clock seventh line CKB7, the second clock fifth line CKB5, the second clock third line CKB3, and the second clock first line CKB1 are arranged in sequence along the first direction.

[0097] Specifically, the second clock eighth line CKB8, the second clock sixth line CKB6, the second clock fourth line CKB4, and the second clock second line CKB2 are arranged in sequence along the first direction.

[0098] Specifically, in the above embodiments, the second clock signal line CKB is described by taking eight clock lines as an example, but the embodiments of the present application are not limited thereto. The second clock signal line CKB may include other numbers of clock lines, for example, it may include 4 clock lines or 16 clock lines.

[0099] Specifically, in every four levels of the first type of gate circuits 22a, the positions of the connections of the second pull-up transistors T22j of each level of the first type of gate circuits 22a to the first group of sub-lines CKBi are different.

[0100] Specifically, in every four levels of the first type of gate circuits 22a, the positions of the connections of the third pull-up transistors T23j of each level of the first type of gate circuits 22a to the second group of sub-lines CKBj are different.

[0101] In some embodiments, as Figures 8 to 23 shown, the first low-potential signal line VGL1 is disposed on the second source-drain layer 223. By disposing the first low-potential signal line VGL1 on the second source-drain layer 223, the first low-potential signal line VGL1 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0102] In some embodiments, as Figure 5 、 Figures 8 to 23 、 Figure 24 to Figure 29 shown, the first type of gate circuit 22a includes a first inverting module 315 and a first pull-up module 312. The first inverting module 315 and the first pull-up module 312 are electrically connected to a first pull-up node Q1[n]. The projection of the first low-potential signal line VGL1 on the substrate 211 is located between the projection of the first inverting module 315 on the substrate 211 and the projection of the first pull-up module 312 on the substrate 211. By disposing the first low-potential signal line between the projection of the first inverting module 315 on the substrate 211 and the projection of the first pull-up module 312 on the substrate 211, the first low-potential signal line VGL1 does not need to occupy additional space, and the first low-potential signal line does not affect the normal operation of the first pull-up module.

[0103] In some embodiments, as Figures 8 to 23 shown, the second low-potential signal line VGL2 is disposed on the second source-drain layer 223. By disposing the second low-potential signal line VGL2 on the second source-drain layer 223, the second low-potential signal line VGL2 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0104] In some embodiments, as Figure 5 、 Figures 8 to 23 , Figure 24 to Figure 29 As shown in Figure 24 to Figure 29 , the first type of gate circuit 22a includes a first pull-up module 312. The projection of the second low-potential signal line VGL2 on the substrate 211 overlaps with the projection of the first pull-up module 312 on the substrate 211. By making the projection of the second low-potential signal line VGL2 on the substrate 211 overlap with the projection of the first pull-up module 312 on the substrate 211, the second low-potential signal line VGL2 does not need to occupy additional space, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0105] In some embodiments, as Figures 8 to 23 shown, the second reset control line VST2 is disposed on the second source-drain layer 223. By making the second reset control line VST2 disposed on the second source-drain layer 223, the second reset control line VST2 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0106] In some embodiments, as Figure 6 , Figures 8 to 23 , Figure 30 to Figure 35 shown, the second type of gate circuit 22b includes a second reset module 327. The second reset module 327 is electrically connected to the second reset control line VST2. The projection of the second reset control line VST2 on the substrate 211 is located between the projection of the first type of gate circuit 22a on the substrate 211 and the projection of the second reset module 327 on the substrate 211. By making the projection of the second reset control line VST2 on the substrate 211 located between the projection of the first type of gate circuit 22a on the substrate 211 and the projection of the second reset module 327 on the substrate 211, the second reset control line VST2 does not need to occupy additional lateral space, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel. Moreover, the distance between the second reset control line VST2 and the second reset module 327 is small, and the length of the connection line between the second reset control line VST2 and the second reset module 327 is small or even no connection line needs to be provided, further reducing the space occupied by the second reset control line VST2 and reducing the border of the display panel.

[0107] In some embodiments, as Figures 8 to 23As shown, at least one of the third clock signal line CKC, the first high potential signal line VGH1, the second high potential signal line VGH2, and the third low potential signal line VGL3 is disposed on the second source-drain layer 223. By disposing at least one of the third clock signal line CKC, the first high potential signal line VGH1, the second high potential signal line VGH2, and the third low potential signal line VGL3 on the second source-drain layer 223, the lateral space occupied by the signal lines electrically connected to the gate driving circuit can be reduced, and the border of the display panel can be reduced.

[0108] Specifically, compared with the related display device in which each signal line connected to the gate driving circuit needs to be disposed on the first source-drain layer and needs to extend from the routing area to the transistor area, resulting in a relatively large lateral space occupied, in the embodiment of the present application, by disposing the signal lines connected to the gate driving circuit on the second source-drain layer, the width of the first source-drain layer is reduced, and the distance between the signal lines disposed on the second source-drain layer and the connected transistors can be shortened, thereby reducing the space occupied by the connection lines, reducing the space occupied by the gate driving circuit, and reducing the border of the display panel.

[0109] In some embodiments, as Figures 8 to 23 shown, the first high potential signal line VGH1 is disposed on the second source-drain layer 223. By disposing the first high potential signal line VGH1 on the second source-drain layer 223, the first high potential signal line VGH1 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0110] In some embodiments, as Figure 7 , Figures 8 to 23 , Figure 36 to Figure 41 shown, the third type of gate circuit 22c includes a third pull-up control module 331, and there is an overlap between the projection of the first high potential signal line VGH1 on the substrate 211 and the projection of the third pull-up control module 331 on the substrate 211. By making the projection of the first high potential signal line VGH1 on the substrate 211 overlap with the projection of the third pull-up control module 331 on the substrate 211, the first high potential signal line VGH1 does not need to occupy additional space, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel, and the first high potential signal line VGH1 can be directly connected to the third pull-up control module, reducing the length of the connection line, further reducing the occupied space, and reducing the border of the display panel.

[0111] In some embodiments, as Figures 8 to 23As shown, the third clock signal line CKC is disposed on the second source-drain layer 223. By disposing the third clock signal line CKC on the second source-drain layer 223, the third clock signal line CKC does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0112] Specifically, it can be understood that each clock signal line in the display panel 2 includes multiple clock lines. The multiple clock lines will occupy a large space of the first source-drain layer, and the multiple clock lines disposed outside the transistor region and connected to the transistor by extending into the transistor region will further occupy space, resulting in a large lateral occupied space of the gate driving circuit 22 and a large border of the display panel 2. In the embodiment of the present application, by disposing the third clock signal line CKC on the second source-drain layer 223, the lateral space occupied by the clock signal line can be reduced, and the border of the display panel 2 can be reduced.

[0113] In some embodiments, as Figure 7 、 Figures 8 to 23 、 Figure 36 to Figure 41 shown, the third type of gate circuit 22c includes a third pull-up control module 331, and the projection of the third clock signal line CKC on the substrate 211 overlaps with the projection of the third pull-up control module 331 on the substrate 211. By making the projection of the third clock signal line CKC on the substrate 211 overlap with the projection of the third pull-up control module 331 on the substrate 211, the first clock signal line does not need to occupy additional space, reducing the space occupied by the gate driving circuit and reducing the border of the display panel 2.

[0114] Specifically, the third clock signal line CKC may include a third clock first line CKC1, a third clock second line CKC2, a third clock third line CKC3, and a third clock fourth line CKC4. Every four levels of the second type of gate circuit 22b are cyclically connected to these four third clock signal lines CKC. For example, the first-level to fourth-level second type of gate circuits 22b are respectively connected to the third clock first line CKC1, the third clock second line CKC2, the third clock third line CKC3, and the third clock fourth line CKC4. The fifth-level to eighth-level second type of gate circuits 22b are respectively connected to the third clock first line CKC1, the third clock second line CKC2, the third clock third line CKC3, and the third clock fourth line CKC4. Similarly, the clock signal lines connected to other levels of the second type of gate circuit 22b can be determined.

[0115] Specifically, the third clock fourth line CKC4, the third clock third line CKC3, the third clock second line CKC2, and the third clock first line CKC1 are arranged in sequence along the first direction.

[0116] Specifically, in the above embodiments, the third clock signal line CKC is described by taking four clock lines as an example, but the embodiments of the present application are not limited thereto. The third clock signal line CKC may include other numbers of clock lines, for example, it may include eight clock lines.

[0117] Specifically, in every four-stage second type of gate circuit 22b, the positions of the connections of each stage of the second type of gate circuit 22b to the third clock signal line CKC are different.

[0118] In some embodiments, as Figures 8 to 23 shown, the second high potential signal line VGH2 is disposed on the second source-drain layer 223. By disposing the second high potential signal line VGH2 on the second source-drain layer 223, the second high potential signal line VGH2 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0119] In some embodiments, as Figure 7 , Figures 8 to 23 , Figure 36 to Figure 41 shown, the third type of gate circuit 22c includes a third pull-up module 332. The third pull-up module 332 is electrically connected to the second high potential signal line VGH2. There is an overlap between the projection of the second high potential signal line VGH2 on the substrate 211 and the projection of the third pull-up module 332 on the substrate 211. By making there be an overlap between the projection of the second high potential signal line VGH2 on the substrate 211 and the projection of the third pull-up module 332 on the substrate 211, the second high potential signal line VGH2 does not need to occupy additional space, reducing the space occupied by the gate driving circuit, reducing the border of the display panel 2, and the second high potential signal line VGH2 can be directly connected to the third pull-up module 332, shortening the length of the connection line or even eliminating the connection line, further reducing the space occupied by the second high potential signal line VGH2 and reducing the border of the display panel.

[0120] In some embodiments, as Figures 8 to 23 shown, the third low potential signal line VGL3 is disposed on the second source-drain layer 223. By disposing the third low potential signal line VGL3 on the second source-drain layer 223, the third low potential signal line VGL3 does not need to occupy the lateral space of the first source-drain layer 221, reducing the lateral space occupied by the gate driving circuit 22 and reducing the border of the display panel.

[0121] In some embodiments, as Figure 7 , Figures 8 to 23 , Figure 36 to Figure 41As shown, the third type of gate circuit 22c includes a third pull-down module 333. The third pull-down module 333 is electrically connected to the third low-potential signal line VGL3. The projection of the third low-potential signal line VGL3 on the substrate 211 overlaps with the projection of the third pull-down module 333 on the substrate 211. By making the projection of the third low-potential signal line VGL3 on the substrate 211 overlap with the projection of the third pull-down module 333 on the substrate 211, the third low-potential signal line VGL3 does not need to occupy extra space, reducing the space occupied by the gate driving circuit and reducing the border of the display panel 2. Moreover, the third low-potential signal line VGL3 can be directly connected to the third pull-down module 333, shortening the length of the connection line or even eliminating the connection line, further reducing the space occupied by the third low-potential signal line VGL3 and reducing the border of the display panel.

[0122] In some embodiments, as Figures 8 to 23 shown, the first clock signal line CKA, the second clock signal line CKB, the third clock signal line CKC, the first high-potential signal line VGH1, the second high-potential signal line VGH2, the first low-potential signal line VGL1, the second low-potential signal line VGL2, the third low-potential signal line VGL3, the first reset control line VST1, the second reset control line VST2, and the low-frequency signal line LC are all disposed on the second source-drain layer. By disposing the first clock signal line CKA, the second clock signal line CKB, the third clock signal line CKC, the first high-potential signal line VGH1, the second high-potential signal line VGH2, the first low-potential signal line VGL1, the second low-potential signal line VGL2, the third low-potential signal line VGL3, the first reset control line VST1, the second reset control line VST2, and the low-frequency signal line LC on the second source-drain layer, the lateral space occupied by the gate driving circuit can be further reduced, and the border of the display panel can be reduced.

[0123] Specifically, the second clock signal line CKB includes a first group of sub-lines CKBi and a second group of sub-lines CKBj.

[0124] Specifically, the first reset control line VST1, the low-frequency signal line LC, the first clock signal line CKA, the first low-potential signal line VGL1, the first group of sub-lines CKBi, the second low-potential signal line VGL2, the second reset control line VST2, the second group of sub-lines CKBj, the first high-potential signal line VGH1, the third clock signal line CKC, the second high-potential signal line VGH2, and the third low-potential signal line VGL3 are arranged along the first direction X.

[0125] In some embodiments, as Figure 5As shown, the first type of gate circuit 22a includes a first pull-up module 312. The second clock signal line CKB includes a first group of sub-lines CKBi and a second group of sub-lines CKBj. The first pull-up module 312 includes:

[0126] A first pull-up transistor T21j. The first electrode of the first pull-up transistor T21j is electrically connected to the first clock signal line CKA. The second electrode of the first pull-up transistor T21j is electrically connected to the stage transmission signal terminal Cout[n] of the current stage of the first type of gate circuit 22a.

[0127] A second pull-up transistor T22j. The first electrode of the second pull-up transistor T22j is electrically connected to the first group of sub-lines CKBi. The second electrode of the second pull-up transistor T22j is electrically connected to the first signal output terminal Gn[m] of another stage of the first type of gate circuit 22a.

[0128] A third pull-up transistor T23j. The first electrode of the third pull-up transistor T23j is electrically connected to the second group of sub-lines CKBj. The second electrode of the third pull-up transistor T23j is electrically connected to the first signal output terminal Gn[n] of the current stage of the first type of gate circuit 22a. By enabling a single stage of the first type of gate circuit 22a to have the first signal output terminals of two stages of the first type of gate circuit, a single stage of the first type of gate circuit can occupy the space of two stages of the first type of gate circuit, thereby shortening the lateral space occupied by the first type of gate circuit and reducing the border.

[0129] Specifically, in the embodiment of the present application, the first signal output terminal Gn[m] of another stage of the first type of gate circuit 22a can be the first signal output terminals of the subsequent stages of the first type of gate circuit 22a. For example, the first signal output terminal Gn[m] of another stage of the first type of gate circuit 22a can be the first signal output terminal of the next stage of the first type of gate circuit 22a. Taking n as 3 as an example, then m can be 4. However, the embodiment of the present application is not limited thereto. The first signal output terminal Gn[m] of another stage of the first type of gate circuit 22a can be the first signal output terminals of the next two stages of the first type of gate circuit 22a or the first signal output terminals of other stages of the first type of gate circuit 22a.

[0130] Specifically, it can be understood that compared with the case where the first type of gate circuit in the comparison display device has only one first signal output terminal, each stage of the first type of gate circuit is connected to a corresponding first signal output terminal. In the embodiment of the present application, the first type of gate circuit of one stage has two first signal output terminals. Accordingly, the first type of gate circuit can be shortened by half. Accordingly, the first signal output terminals connected to each first type of gate circuit can be arranged in sequence. For example, the two first signal output terminals of the first stage of the first type of gate circuit can be regarded as the first signal output terminal of the first stage of the first type of gate circuit and the first signal output terminal of the second stage of the first type of gate circuit in the comparison display device. Similarly, the first signal output terminals of other stages of the first type of gate circuit can be determined.

[0131] Specifically, the gate driving circuit includes a plurality of transistors (such as a first pull-up control transistor and a first pull-up transistor), and the pixel driving circuit includes a plurality of transistors (such as a driving transistor and a switching transistor).

[0132] In some embodiments, the mobility of at least one transistor in the gate driving circuit 22 is greater than the mobility of the transistors in the pixel driving circuit 21; thereby, the size of the transistors in the gate driving circuit can be reduced, thereby reducing the occupied space of the gate driving circuit 22 and reducing the border.

[0133] Specifically, when the mobility of at least one transistor in the gate driving circuit 22 is greater than the mobility of the transistors in the pixel driving circuit 21, for example, the mobility of the first inverter transistor in the gate driving circuit 22 is greater than the mobility of the initialization transistor in the pixel driving circuit 21. However, the embodiments of the present application are not limited thereto. The mobility of other transistors in the gate driving circuit can be greater than the mobility of the transistors in the pixel driving circuit, or the mobility of multiple transistors in the gate driving circuit is greater than the mobility of the transistors in the pixel driving circuit.

[0134] Specifically, the materials of the active parts of the transistors in the gate driving circuit can be the same, the materials of the active parts of the transistors in the pixel driving circuit can be the same, and the mobility of the active parts of the transistors in the gate driving circuit is greater than the mobility of the transistors in the pixel driving circuit.

[0135] Specifically, the mobility of the active parts of the transistors in the gate driving circuit can be greater than 20. For example, the materials of the active parts of the transistors in the gate driving circuit are Ln-IZO (indium zinc oxide doped with lanthanide elements) and IGZTO (indium gallium zinc tin oxide), and the materials of the active parts of the transistors in the pixel driving circuit are indium gallium zinc oxide, so that the area of the transistors in the gate driving circuit can be relatively small.

[0136] Specifically, in order to improve the performance of the transistor, the area of the transistor is generally made larger. For example, when indium gallium zinc oxide is used as the material of the active part, the channel width of the transistor needs to be 1000 and the length needs to be 5 to meet the electrical requirements of the transistor. In the embodiments of the present application, by making the mobility of the transistors in the gate driving circuit greater than the mobility of the transistors in the pixel driving circuit, the area of the transistors can be reduced, still meeting the electrical requirements, reducing the occupied area of the transistors, and reducing the border of the display panel.

[0246] Among them, the fourth pull-up control transistor T11i and the fifth pull-up control transistor T12i are arranged along the second direction Y, and the sixth pull-up control transistor T81i and the fourth pull-up control transistor T11i are arranged along the first direction X.
