[0022] This application provides a display panel and a display device.

[0023] Please see Figures 1 to 4This application provides a display panel 100, which includes a display area 100a and a peripheral area 100b surrounding the display area 100a. The display panel 100 includes a driving signal source 10, a gate driving circuit 20, and an anti-static module 30. The driving signal source 10 is located along the length of the peripheral area 100b. The gate driving circuit 20 includes a first driving signal line 21 and a second driving signal line 22. The first driving signal line 21 extends from the left side of the peripheral area 100b through the display area 100a to the other side of the display area 100a. The second driving signal line 22 extends from the right side of the peripheral area 100b through the display area 100a to the other side of the display area 100a. The first driving signal line 21 and the second driving signal line 22 are staggered along their width. The first driving signal line 21 and the second driving signal line 22 are connected to the driving signal source 10. The anti-static module 30 is connected to the ends of the first driving signal line 21 and the second driving signal line 22, respectively.

[0024] The drive signal source 10 is located along the length of the peripheral area 100b and is used to provide drive signals. The gate drive circuit 20 includes a first drive signal line 21 and a second drive signal line 22. These two signal lines extend from the left and right sides of the peripheral area 100b through the display area 100a to the other side of the display area 100a, and are staggered along the width direction. This staggered distribution design helps optimize the signal transmission path and reduce signal interference. The electrostatic discharge (ESD) prevention module 30 is connected to the ends of the first drive signal line 21 and the second drive signal line 22 to prevent ESD damage to the circuit.

[0025] Specifically, the drive signal source 10 can be one or more signal generators used to generate drive signals. The anti-static module 30 can include multiple electrostatic discharge devices for rapid discharge of static electricity and protection of the circuit. In addition, the anti-static module 30 may also include an overvoltage protection unit for cutting off the circuit when the voltage is too high to prevent circuit damage.

[0026] The display panel 100 of this application effectively reduces the impact of static electricity on the display panel 100 by optimizing the signal line layout of the gate drive circuit 20 and adding an anti-static module 30. Compared with the prior art, the technical solution of this application can significantly improve the anti-static capability of the display panel 100, reduce electrostatic discharge phenomena during the production process, and thus improve the product yield. Specifically, by combining the staggered signal lines and the anti-static module 30, this application can effectively prevent static electricity from damaging the gate drive circuit 20 and surrounding circuits, ensuring the stability and reliability of the display panel 100.

[0027] Furthermore, this application proposes that the anti-static module includes a first terminal 31, a second terminal 32, and a third terminal 33. The first terminal 31 is connected to the gate driving circuit 20, the second terminal 32 is connected to a high-level signal source 34, and the third terminal 33 is connected to a low-level signal source 35. Specifically, the first terminal 31 is connected to the gate driving circuit 20 through a first via 30a, the second terminal 32 is connected to the high-level signal source 34 through a second via 30b, and the third terminal 33 is connected to the low-level signal source 35 through a third via 30c.

[0028] When a full-screen pull-down setting is required, the gate drive circuit 20 does not need to operate; instead, a high-level signal is output directly from the high-level signal source 34, transferring the voltage from the low-level signal source 35 to the gate drive circuit 20. This design allows for a fast response and reduces signal delay. The anti-static module is connected to the gate drive circuit 20, the high-level signal source 34, and the low-level signal source 35 via three terminals. This design effectively reduces the impact of static electricity on the display panel 100, improving its anti-static capability. The gate drive circuit 20 is not disconnected at its end, reducing the probability of static electricity collection. Even if static electricity occurs, the anti-static module can quickly release it, protecting the signal lines from damage.

[0029] Furthermore, this application also proposes that the first endpoint 31 is connected to the gate drive circuit 20 through a first via 30a. The first via 30a is a conductive channel used to connect circuits between different layers, typically implemented by forming a through-hole in an insulating layer and filling it with a conductive material. Specific implementations of the first via 30a may include, but are not limited to, filling the through-hole with a metallic material such as copper or aluminum, or using a conductive polymer material. In addition, the size and shape of the first via 30a can be adjusted according to specific circuit design requirements, for example, using a circular, square, or other geometrically shaped via.

[0030] Specifically, the placement of the first via 30a effectively reduces the resistance between circuit layers, improving the reliability of signal transmission. Connecting the first terminal 31 and the gate drive circuit 20 via 30a ensures that the signal will not attenuate or distort during transmission due to poor interlayer connectivity. Furthermore, the design of the first via 30a can also consider heat dissipation and mechanical strength requirements, such as by incorporating heat dissipation structures or reinforcing materials around the via, to improve the overall circuit stability and durability.

[0031] Therefore, the technical solution of this application connects the first terminal 31 and the gate driving circuit 20 through the first via 30a, solving the signal transmission problem caused by poor interlayer connection in the prior art. Compared with the prior art, this solution not only improves the reliability of signal transmission, but also enhances the stability and durability of the circuit, thereby effectively improving the overall performance of the display panel 100.

[0032] Furthermore, this application proposes that the second terminal 32 is connected to the high-level signal source 34 via a second via 30b. Specifically, the second via 30b is a conductive structure used to connect different circuit layers, typically achieved by forming a through-hole in an insulating layer and filling it with conductive material. The design of the second via 30b ensures a stable and reliable electrical connection between the high-level signal source 34 and the second terminal 32, while reducing signal loss and interference during transmission. As a preferred embodiment, the second via 30b can be made of a material with good conductivity, such as copper or aluminum, and its diameter and depth can be adjusted according to specific circuit design requirements.

[0033] Therefore, the technical solution of this application connects the second terminal 32 to the high-level signal source 34 through the second via 30b, which can effectively reduce the impact of static electricity on the display panel 100. Specifically, the design of the second via 30b not only improves the anti-static capability of the circuit but also enhances the stability of signal transmission. Compared with the prior art, the technical solution of this application avoids the problem of the gate drive signal line end being left floating by optimizing the connection structure, thereby reducing the damage to the circuit caused by static electricity collection and release. This design can significantly improve the product yield of the display panel 100 in actual production and has high practicality and reliability.

[0034] Furthermore, this application proposes that the third terminal 33 is connected to the low-level signal source 35 via a third via 30c. Specifically, the third via 30c is a conductive channel used to connect different circuit layers. Through this via, the third terminal 33 can be electrically connected to the low-level signal source 35. This connection method can effectively reduce signal transmission losses and improve circuit stability. As a preferred embodiment, the third via 30c can be made of a metallic material, such as copper or aluminum, to ensure good conductivity.

[0035] In terms of technical implementation, the third via 30c can be created during the manufacturing process of the display panel 100 using photolithography. Specifically, an insulating layer is first formed on the substrate of the display panel 100, then a via is formed on the insulating layer using photolithography and etching processes, and finally, conductive material is filled into the via to form the third via 30c. In this way, the connection between the third terminal 33 and the low-level signal source 35 is achieved, thereby ensuring that the low-level signal of the circuit can be transmitted stably.

[0036] Therefore, the technical solution of this application connects the third terminal 33 to the low-level signal source 35 through the third via 30c, solving the problem of circuit performance degradation caused by unstable signal transmission in the prior art. Compared with the prior art, this solution not only improves the reliability of the circuit but also simplifies the manufacturing process and reduces production costs. Specifically, by setting the third via 30c, interference during signal transmission can be effectively reduced, ensuring stable transmission of low-level signals, thereby improving the overall performance of the display panel 100.

[0037] Furthermore, this application proposes that a shielding layer be provided at the connection point of the anti-static module between the first drive signal line 21 and the second drive signal line 22. The shielding layer serves to prevent electrostatic interference to the drive signal lines, especially in the area where the anti-static module connects to the drive signal lines, where electrostatic discharge can easily be conducted through the metal wires and affect the normal operation of the circuit. The shielding layer can be made of a metallic material, such as copper or aluminum, and its thickness can be adjusted according to actual needs to ensure sufficient shielding effect. The shielding layer can be integrated with the drive signal lines through a deposition process or a bonding process. Specifically, the shielding layer can cover the surface of the drive signal lines or be isolated from the drive signal lines by an insulating layer to avoid short circuits.

[0038] Specifically, the shielding layer effectively reduces electrostatic interference on the drive signal lines, especially at the ends of the drive signal lines where they connect to the anti-static module. Electrostatic discharge (ESD) can easily be conducted through metal wires and affect the normal operation of the circuit. The shielding layer blocks the conduction path of ESD, thereby protecting the drive signal lines and preventing the ESD module from malfunctioning. Furthermore, the shielding layer also reduces the impact of external electromagnetic interference on the drive signal lines, improving the stability and reliability of the circuit.

[0039] Therefore, the technical solution of this application effectively solves the problem of electrostatic interference to the drive signal lines in the prior art by setting a shielding layer at the anti-static module connection of the first drive signal line 21 and the second drive signal line 22. Compared with the prior art, this solution not only improves the anti-static capability of the display panel 100, but also enhances the stability and reliability of the circuit, thereby improving the overall performance of the display panel 100.

[0040] Furthermore, this application proposes that the gate drive circuit 20 employs a serpentine routing configuration. Serpentine routing is a common circuit routing method, characterized by arranging signal lines on the circuit board in a serpentine manner, thereby increasing the length of the signal lines and reducing interference between them. Specifically, serpentine routing can be achieved by setting multiple bends on the circuit board; these bends can be right-angle bends, arc bends, or other shapes. In this way, the signal lines can extend their path within a limited space, thereby reducing electromagnetic interference and crosstalk during signal transmission.

[0041] Furthermore, this application also proposes that the anti-static module 30 includes an overvoltage protection unit connected to the gate drive circuit 20.

[0042] Specifically, an overvoltage protection unit is a circuit module used to prevent voltage from exceeding a set threshold. Its main function is to quickly cut off the circuit or absorb excess voltage when the voltage rises abnormally, thus protecting the circuit from damage. Overvoltage protection units can be implemented in various ways, such as using transient voltage suppressor diodes (TVS diodes), varistors (MOVs), or gas discharge tubes. These components can quickly conduct when the voltage exceeds a certain value, guiding the excess voltage to ground or other low-potential points, thereby protecting the gate drive circuit 20 from electrostatic discharge or voltage surges.

[0043] In a preferred embodiment, the overvoltage protection unit can be integrated into the anti-static module 30 and connected to the gate drive circuit 20 via a wire or via. The input terminal of the overvoltage protection unit is connected to the signal line of the gate drive circuit 20, while the output terminal is grounded or connected to a low potential point. When an overvoltage occurs on the signal line of the gate drive circuit 20 due to static electricity or other reasons, the overvoltage protection unit will respond quickly, guiding the overvoltage to a safe path to prevent damage to the gate drive circuit 20.

[0044] Therefore, the technical solution of this application effectively solves the problem of damage to the gate drive circuit 20 caused by electrostatic discharge in the existing display panel 100 by introducing an overvoltage protection unit. Compared with the prior art, this solution not only improves the anti-static capability of the display panel 100, but also simplifies the circuit design and reduces production costs. Specifically, the introduction of the overvoltage protection unit enables the gate drive circuit 20 to respond quickly and protect itself in the event of electrostatic discharge or voltage surge, thereby significantly improving the reliability and service life of the display panel 100.

[0045] Furthermore, this application proposes that the electrostatic discharge (ESD) prevention module 30 integrate multiple ESD devices. Specifically, these ESD devices may include, but are not limited to, transient voltage suppressor diodes (TVS diodes), gas discharge tubes (GDTs), and varistor-type resistors (MOVs). These devices can effectively absorb and release static electricity, thereby protecting the gate drive circuit 20 in the display panel 100 from damage caused by ESD. For example, a TVS diode can quickly conduct when the ESD voltage exceeds a certain threshold, guiding the ESD energy to ground, thus preventing damage to the circuit. A gas discharge tube can form an electric arc under high voltage, releasing the ESD energy into the air. A varistor, through its nonlinear resistance characteristics, rapidly reduces its resistance value when the ESD voltage increases, thereby absorbing the ESD energy.

[0046] Specifically, the integration of multiple electrostatic discharge (ESD) devices can be achieved in various ways. For example, a TVS diode, a gas discharge tube, and a varistor can be connected in parallel on the signal lines of the gate drive circuit 20 to provide multi-level ESD protection. Furthermore, these ESD devices can be integrated into a single package module, thereby simplifying circuit design and improving module reliability. As a preferred embodiment, the ESD devices can be directly soldered onto the circuit board of the display panel 100 using surface mount technology (SMT), thereby reducing the length of the connecting wires, lowering parasitic inductance, and improving ESD discharge efficiency.

[0047] Therefore, the technical solution of this application, by integrating multiple electrostatic discharge devices, can effectively reduce the impact of static electricity on the display panel 100 and improve the anti-static capability of the display panel 100. Compared with the prior art, this solution not only provides multi-level electrostatic protection, but also simplifies the circuit structure through integrated design, improving circuit reliability and production efficiency. Specifically, by integrating multiple electrostatic discharge devices into one module, the number of components on the circuit board can be reduced, production costs can be lowered, and the response speed and effectiveness of electrostatic protection can be improved.
