The scanning signal transmission line 330 comprises a plurality of first signal transmission units 331 being parallel to the data lines 341, and a first jumper 332 connected to two adjacent first signal transmission units 331. The first jumper 332 and the first signal transmission units 331 are arranged on different layers, and the first jumper 332 is electrically connected to the two adjacent first signal transmission units 331 by a through-hole. Refer to FIG. 4 for details. The scanning signal transmission line 330 is on the gate layer, and a same photomask process as the gate is used for the scanning signal transmission line 330 to better connect to the gate. In order to prevent the scanning signal transmission line 330 from not being connected to a non-corresponding gate, the jumper arrangement is required to prevent being short-circuiting, thereby achieving a stable and good connection effect between the scanning signal transmission line 330 and the gate.

In the present embodiment, the scanning signal transmission line 330 and the source/drain layer 340 in the driving circuit layer 300 are arranged in a same layer. The scanning signal transmission line 330 is electrically connected to the gate layer in the driving circuit layer 300 by a through-hole. Refer to FIG. 3 for details. The scanning signal transmission line 330 and the source/drain are arranged in a same layer, and the scan signal transmission line 330, the source/drain layer 340, and the data lines 341 can be simultaneously formed through a same mask process, which simplifies processes while avoiding a jumper process.

Since film structure of the light-shielding layer 700 is not very complicated, there can be more space for setting the scanning signal transmission line 330, and the standard for etching precision of etching process is not very high, which saves costs and reduces difficulty of processes.

In the present embodiment, the scanning signal transmission line 330 and the semiconductor layer in the driving circuit layer 300 are arranged in a same layer. The scanning signal transmission line 330 is electrically connected to the gate layer in the driving circuit layer 300 by a through-hole, which is similar to the scanning signal transmission line 330 and the light-shielding layer 700 in the driving circuit layer 300 being arranged in a same layer. Reference may be made to the arrangement of FIG. 6, which will not be repeated here. The scanning signal transmission line and a semiconductor layer are arranged in a same layer, and the semiconductor layer comprises the active layer. Since film structure of the semiconductor layer is not very complicated, there can be more space for setting the scanning signal transmission line 330, and the standard for etching precision of etching process is not very high, which saves costs and reduces difficulty of processes.

In the present embodiment, the scanning signal transmission line 330 comprises a first scanning signal transmission line 3310 and a second scanning signal transmission line 3320. The first scanning signal transmission line 3310 is connected in parallel with the second scanning signal transmission line 3320. The first scanning signal transmission line 3310 and the gate layer in the driving circuit layer 300 are arranged in a same layer, and the second scanning signal transmission line 3320 and the source/drain layer 340 in the driving circuit layer 300 are arranged in a same layer. The first scanning signal transmission line 3310 comprises a plurality of second signal transmission units 333 being parallel to the data lines 341, and a second jumper 334 connected to two adjacent second signal transmission units 333. Refer to FIG. 0.5 for details. The scanning signal transmission line 330 reduces resistance of the scanning signal transmission line 330 by connecting to the first scan signal transmission line 3310 and the second scan signal transmission line 3320 in parallel, while preventing one of the scanning signal transmission lines 330 from experiencing failure to display normally, and reducing probability of display failure.

In the present embodiment, the first scanning signal transmission line 3310 may be arranged in a same layer as any one of the gate layer, the semiconductor layer, the light-shielding layer 700, and the source/drain layer 340. The second scanning signal transmission line 3320 and the first signal transmission line are arranged on different layers, and the first scanning signal transmission line 3310 is connected in parallel with the second scanning signal transmission line 3320. When the first scanning signal transmission line 3310 or the second scanning signal transmission line 3320 is arranged in a same layer as the gate layer, the first scanning signal transmission line 3310 or the second scanning signal transmission line 3320 adopts a jumper arrangement. For specific jumper arrangement, refer to the arrangement of the first jumper 332 and the arrangement of the second jumper 334. Refer to FIG. 5 for details, and the details are not described herein again.

In the present embodiment, the first flip-chip film layer 510 and the second flip-chip film layer 520 may be arranged in a same layer. In order to prevent the scan signal transmission line 330 from being connected to the data signal transmission line resulting in short-circuiting, when the scanning signal transmission line 330 and the data signal transmission line are arranged in a same layer, and any one of transmission line type in the scanning signal transmission line 330 or the data signal transmission line has a jump arrangement. The specific jumper arrangement is not described here.

In the present embodiment, a length of the scanning signal transmission line 330 is gradually decreased in a direction from a side of the display panel 100 to the central region of the display panel 100. Refer to FIG. 1 for details. The scanning lines connected to the scanning signal transmission line 330 and close to the central region of the display panel 100 are closer to the bottom edge of the display panel 100, which reduces the length of the scanning signal transmission line 330 close to the central region of the display panel 100, thereby saving materials and reducing its resistance values. This structural arrangement can allow resistance values of each scanning signal transmission line 330 to tend to be same.

In the present embodiment, a cross-sectional area of the scanning signal transmission line 330 away from the central region of the display panel 100 is greater than a cross-sectional area of the scanning signal transmission line 330 close to the central region of the display panel 100. In the display region of the display panel 100, the scanning signal transmission line 330 on both sides has a greater length, and a large cross-sectional area is required to reduce resistance, so that the resistance values of the scanning signal transmission lines 330 tend to be same.

In the present embodiment, a material of the scanning signal transmission line 330 is a transparent material, and the transparent material may comprise fine metal wires (Ag, Cu, Al, etc.), nano silver wires, graphene, indium tin oxide, or carbon nanotubes, and it is not limited herein. Therefore, light transmittance of the display panel 100 may be better increased, thereby increasing display aperture ratio and facilitating setting of position structure.

In the present embodiment, the scanning signal transmission line 330 comprises a third scanning signal transmission line and a fourth scanning signal transmission line. The third scanning signal transmission line is away from the central region of the display panel 100, and the fourth scanning signal transmission line is close to the central region of the display panel 100. The fourth scanning signal transmission line comprises a fourth horizontal scanning signal transmission line and a fourth vertical scanning signal transmission line. The fourth horizontal scanning signal transmission line is parallel to the gate lines 311, and the fourth vertical scanning signal transmission line is parallel to the third scanning signal transmission line. An orthographic projection of the fourth vertical scanning signal transmission line on a film layer of the third scanning signal transmission line coincides with the third scanning signal transmission line. The fourth vertical scanning signal transmission line and the third scanning signal transmission line are arranged in different layers. Directing the scanning signal transmission line 330 close to a center of the display panel 100 away from the center of the display panel 100 reduces the jumper while being close to the thin film electrode layer, and prevents excessive jumper punching from reducing strength of a floor structure of the display panel 100.

In the present embodiment, the data lines 341 comprise a first data line 342 and a plurality of first data connection lines 343. The first data line 342 is arranged in parallel with the scanning signal transmission line 330, and the first data connection lines 343 are connected to the first data line 342 and the source/drain layer 340 of the driving circuit layer 300. Wherein, connecting directions of two adjacent first data connection lines 343 of any one of the data lines 341 are opposite. Refer to FIG. 2 for details. The data lines 341 achieve electrode display effect similar to dot inversion through this connection method, which reduces power consumption, improves display color accuracy, and increases display color gamut.

In the present disclosure, the scanning signal transmission line is disposed in pixel units by directing the scanning signal transmission line to the bottom edge of the display panel through a display region of the display panel, which reduces widths of the other three frames of display screens, increases display aperture ratio of the display panel, and improves display effect.
