According to the display panel provided by the embodiment of the invention, the peripheral area is coated with the double-seal frame glue, namely, the insulating frame glue is coated on the inner side, close to the display area, in the peripheral area, so that the wiring of the peripheral area can be protected through the insulating frame glue; the conductive frame sealing glue is coated on the outer side, far away from the display area, in the peripheral area, so that static electricity on the display panel can be dredged quickly through the conductive frame sealing glue, the static electricity generated in later manufacturing and using of the display panel is led out quickly, and the antistatic capacity of the display panel is improved. In addition, the display panel provided by the embodiment of the invention does not need to change the circuit design of the peripheral area, does not need to additionally increase the wiring line width, does not influence the frame width design of the display panel, does not need to increase additional equipment and manufacturing procedures, and can improve the antistatic capability of the display panel only by endowing the frame sealing glue with additional static electricity dredging capability through the double frame sealing glue design.
Specifically, the frame sealing adhesive is an important material required in the production of the display panel, can firmly adhere the upper and lower substrates of the panel, and can also play a good role in electrostatic shielding for the full coverage of the circuits in the peripheral area on the array substrate. In the prior art, a conventional packaging process of a display panel is simple, as shown in fig. 2, the process mainly includes: frame sealing glue dripping, liquid crystal injection, panel assembly and frame sealing glue curing through ultraviolet light; the main components of the frame sealing glue are resin and initiator, the cross-linked and cured frame sealing glue can cover and protect circuit wires in the peripheral area of the array substrate, but the static electricity around the display panel is not dredged, and the antistatic capability of the display panel cannot be improved. The invention adopts a double-seal frame glue structure, as shown in fig. 3, the insulating frame seal glue 021 is coated on the inner side of the peripheral area close to the display area, so that the wiring of the peripheral area can be protected by the insulating frame seal glue; the conductive frame sealing glue 022 is coated on the outer side of the peripheral region far away from the display region, so that static electricity on the display panel can be quickly dredged through the conductive frame sealing glue, that is, extra static electricity dredging capability is given to the frame sealing glue, and the antistatic capability of the display panel is further improved.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the conductive frame sealing adhesive is a frame sealing adhesive filled with conductive capsules, and the number of the conductive capsules filled in the conductive frame sealing adhesive is greater than the conductive threshold. Specifically, in the display panel provided in the embodiment of the present invention, the common frame sealing adhesive is filled with the conductive capsules with the parts larger than the conductive threshold, so that the frame sealing adhesive has a conductive function, as shown in fig. 4, when the parts of the conductive capsules filled in the frame sealing adhesive is larger than the conductive threshold, the conductivity of the frame sealing adhesive increases accordingly. The conductive capsules are uniformly dispersed in the frame sealing glue and are contacted with each other, so that when weak static electricity is encountered, the static electricity can be led out of the display panel through the contacted conductive capsules; when strong static electricity is encountered, the conductive capsule absorbs the static electricity energy through self-explosion, and a new conductive layer is exposed after the self-explosion, so that the function of dredging the static electricity is continuously performed.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the size of the conductive capsule is the same as the size of the silicon ball in the conductive frame sealing adhesive. Specifically, the silicon balls in the common frame sealing glue have the effect of maintaining the uniformity of the box thickness of the display panel, so that the size of the conductive capsules filled in the conductive frame sealing glue needs to be consistent with the size of the silicon balls in the frame sealing glue, and the influence on the box thickness uniformity of the upper substrate and the lower substrate to the box when the display panel is packaged is avoided.
In a specific implementation, in the display panel provided in an embodiment of the present invention, the conductive capsule may include: a plurality of conductive layers and a plurality of insulating layers wrapped around each other; wherein, the innermost layer and the outermost layer of the conductive capsule are conductive layers. Specifically, the structure of the conductive capsule is a multi-layer capsule-shaped structure with a conductive layer and an insulating layer wrapped mutually, wherein the innermost layer and the outermost layer are conductive layers, namely the innermost layer is the conductive layer, then the second layer is the insulating layer wrapping the conductive layer, the insulating layer is wrapped with a conductive layer, and the like to form a multi-layer structure wrapped mutually. As shown in fig. 5, it only shows a three-layer structure, in which the material of the conductive layer D of the innermost layer may be a metal such as copper having excellent conductive performance; the material of the conductive layer D on the outermost layer, i.e., the surface of the conductive capsule, may be a metal such as nickel or aluminum which is easily coated, and the intermediate layer is the insulating layer Y. When strong static electricity is encountered, the conductive capsule absorbs static electricity energy through self-explosion, and a new conductive layer is exposed after the self-explosion, so that the function of dredging the static electricity is continuously achieved.
In practical implementation, in the display panel provided by the embodiment of the present invention, the material of the innermost layer of the conductive capsule may be a metal such as copper with excellent conductive performance, and the material of the conductive layer outside the innermost layer may be a metal such as nickel or aluminum, which is easy to coat. In specific implementation, a suitable metal material may be selected according to actual process production conditions, and is not limited herein.

Specifically, the peripheral area of the display panel is provided with the jumper wire of the transparent conducting layer, so that the conductive frame sealing glue can be connected with the jumper wire, and further connected with the silver glue conductive terminal through the jumper wire, and a path for leading static electricity out of the display panel from the conductive frame sealing glue is formed.
In a specific implementation, as shown in fig. 3, in the display panel provided in the embodiment of the present invention, the width of the insulating frame sealing adhesive 021 is greater than the width of the conductive frame sealing adhesive 022, and the insulating frame sealing adhesive 021 completely covers the trace in the peripheral area. Specifically, the insulating frame sealing adhesive is used as a packaging material of the display panel and needs to completely cover the wires in the peripheral area of the display panel, and the conductive frame sealing adhesive cannot be in contact with the wires in the peripheral area due to the conductive function of the conductive frame sealing adhesive so as to avoid the problem of short circuit; as shown in fig. 1, the conductive frame sealing adhesive cannot be coated on the peripheral area of the display panel where the chip is disposed. Therefore, the width of the insulating frame sealing adhesive needs to be set to be larger than that of the conductive frame sealing adhesive, the insulating frame sealing adhesive is arranged on the inner side close to the display area, the conductive frame sealing adhesive is arranged on the outer side far away from the display area, and the conductive frame sealing adhesive partially surrounds the insulating frame sealing adhesive.

when the chip arranged in the peripheral area close to the display panel controls the pressure controller to stop the glue discharging of the conductive frame sealing glue barrel and increase the glue discharging amount of the insulating frame sealing glue barrel.
Specifically, the insulating frame sealing glue is used as a packaging material of the display panel, and the wires in the peripheral area of the display panel need to be completely covered to protect the wires in the peripheral area from being damaged, so that when the frame sealing glue is coated, the pressure controller needs to be controlled to coat the insulating frame sealing glue on one side, close to the display area, in the peripheral area and surround the display area; the conductive frame sealing glue can not contact with the wiring of the peripheral area due to the conductive function of the conductive frame sealing glue so as to avoid the problem of short circuit, so that the pressure controller needs to be controlled to coat the conductive frame sealing glue on one side of the peripheral area far away from the display area and partially surround the insulating frame sealing glue; as shown in fig. 1, the conductive frame sealing adhesive cannot be coated at the position where the chip is disposed in the peripheral area of the display panel, so that when the chip is disposed in the peripheral area close to the display panel, the pressure controller is controlled to stop the adhesive discharge of the conductive frame sealing adhesive barrel and increase the adhesive discharge amount of the insulating frame sealing adhesive barrel. Thus, the double-frame sealing glue is coated on the peripheral area of the display panel, so that the frame sealing glue has extra static electricity dredging capability, and the antistatic capability of the display panel can be improved.
