All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

Just as the anti-static measures of the existing display panel mentioned in the background art can cause the problem that the pixel points in the display panel, which are relatively close to the static discharge line, are destroyed to form a bright-free spot, the inventor finds that the reason for generating the technical problem is that:

the static electricity discharge line in the display panel is designed in a whole block, static charges are accumulated in a certain sub-area in the whole block static electricity prevention design area, and large static electricity discharge is generated instantaneously, so that pixel points close to the static electricity discharge line are destroyed, and a phenomenon of no bright spots is formed.

Aiming at the technical problems, the invention provides the following solutions:

fig. 1 is a schematic structural view of a display panel according to an embodiment of the present invention, fig. 2 is a schematic enlarged partial view of fig. 1, fig. 3 is a schematic sectional structure of the display panel shown in fig. 1, and, in combination with fig. 1, fig. 2 and fig. 3, the display panel includes a display area AA and a non-display area NAA disposed around the display area AA, and the display panel further includes:

a substrate base 10;

a plurality of electrostatic discharge wires 11 and electrostatic discharge blocks 12 provided on one side of the substrate base plate 10;

the electrostatic discharge wire 11 is disposed around the display area AA in the non-display area NAA, and the plurality of electrostatic discharge blocks 12 are disposed between the electrostatic discharge wire 11 and the display area AA.

In fig. 1, the shape of the display panel is schematically shown as a rectangle, and in other embodiments, the shape of the display panel may also be other shapes, for example, when the display panel is used in a wearable device such as a smart watch, the shape of the display panel may be a circle.

Specifically, the substrate 10 may be a rigid substrate or a flexible substrate, the material of the rigid substrate may be glass, and the material of the flexible substrate may be a polymer material such as polyimide. In addition, the substrate base 10 may have a single-layer structure or a multi-layer structure. When the base substrate 10 is a multilayer structure, inorganic materials such as silicon nitride, silicon oxide, and silicon oxynitride may be interposed between the layers in a single layer or multiple layers.

In this embodiment, as shown in fig. 1, the electrostatic discharge wire 11 may be a straight line, and in other embodiments, the electrostatic discharge wire 11 may also be a zigzag wire or a wave wire, for example, some display screens are currently round display screens or display screens with special-shaped areas, and accordingly, the electrostatic discharge wire 11 needs to be designed into a curved shape or other shapes, which will not be described in detail in this embodiment according to the structural design of the display panel.

In some embodiments, the materials of the electrostatic discharge wire 11 and the electrostatic discharge block 12 may be metal, or may be indium tin oxide, for example, the electrostatic discharge wire 11 and the electrostatic discharge block 12 are disposed on one side of the substrate 10, and when the electrostatic discharge wire 11 and the electrostatic discharge block 12 are disposed on the same layer as the source/drain of the thin film transistor in the pixel circuit, the materials may be the same as the source/drain materials, and when the electrostatic discharge wire 11 and the electrostatic discharge block 12 are disposed on the same layer as the gate of the thin film transistor in the pixel circuit, the materials may be the same as the gate materials. In other words, the electrostatic discharge wire 11 and the electrostatic discharge block 12 may be prepared in the same layer as other conductive layers in the display panel. When the electrostatic discharge wire 11 and the anode are arranged in the same layer, the material of the electrostatic discharge wire and the anode may be the same as that of the anode, i.e. indium tin oxide. By the design, the process of the display panel can be simplified, and better performance is realized.

In order to prevent the phenomenon that the electrostatic discharge wire 11 and the display area AA form an interconnection area, thereby causing static charge to gather, generating larger electrostatic discharge instantly, and damaging the pixel points close to the electrostatic discharge wire to form bright spots, the invention is equivalent to cutting the whole area of the existing electrostatic discharge wire by arranging a plurality of electrostatic discharge blocks 12 between the electrostatic discharge wire 11 and the display area AA so as to disperse static. That is, the static electricity discharge block 12 can make the static electricity part inside the display panel share to the static electricity discharge block 12, so that the current is reduced to avoid static electricity damage caused by overlarge current inside the display panel, and the static electricity discharge block 12 can reduce the width of the static electricity discharge line 11, prevent static electricity from gathering in the static electricity prevention area, further improve the static electricity prevention capability, and avoid damage to the pixel point caused by overlarge current. That is, the electrostatic discharge block 12 is used for dispersing electrostatic charge distribution, preventing electrostatic charge aggregation, generating larger electrostatic discharge instantaneously, causing the phenomenon that pixel points close to the electrostatic discharge line are destroyed, greatly reducing the risk of no bright spots, improving the display effect of the product, and the electrostatic discharge line 11 is used for discharging internal static generated in the production and use processes of the display panel.

The display panel provided by the embodiment of the invention comprises a substrate, an electrostatic discharge wire and a plurality of electrostatic discharge blocks; the internal static electricity generated in the production and use processes of the display panel is released through the static electricity releasing wire, static electricity can be dispersed and distributed through the static electricity releasing blocks arranged between the static electricity releasing wire and the display area, static electricity is prevented from gathering, large static electricity is generated instantaneously, pixel points close to the static electricity releasing wire are damaged, so that static electricity preventing measures are optimized, the generation of bright spots in the display area is reduced, and the product yield and the display effect of the display panel are improved.

The shape, size and arrangement of the static electricity discharge blocks 12 are not particularly limited, as long as static electricity can be dispersed. Illustratively, the static discharge block 12 may have a square shape, or may have a diamond shape, a polygonal shape, or a circular shape. Preferably, the shape of the static electricity discharge block 12 is square. The shape and size of each static discharge block 12 may be the same or different. Several arrangements of the static discharge blocks 12 are described below.

In some embodiments, with continued reference to fig. 1 and 2, the display panel further includes a plurality of subpixels 13 arranged in a plurality of rows and columns; the static discharge blocks 12 are arranged in at least one row and one column, the row arrangement direction of the static discharge blocks 12 is the same as the row arrangement direction of the sub-pixels 13, and the column arrangement direction of the static discharge blocks 12 is the same as the column arrangement direction of the sub-pixels 13.

In particular, when the non-display area NAA of the display panel is provided with a plurality of rows and columns of the static electricity discharge blocks, the shape and size of each row and/or column of the static electricity discharge blocks 12 may be the same or different. Illustratively, the first row of static discharge blocks has a square shape and the second row of static discharge blocks has a diamond shape. Preferably, the shape and size of each row and/or each column of static discharge blocks 12 are the same, and the shape of each row and/or each column of static discharge blocks 12 is square. By the arrangement, when the shapes and the sizes of the static electricity discharge blocks 12 in each row and/or each column are different, the static electricity can be better equally divided, and static electricity accumulation can be prevented.

In some embodiments, the electrostatic discharge block 12 has an overall shape of an inverted U, and the electrostatic discharge block 12 is spaced from the sub-pixel 13 by a distance greater than 0.5mm. That is, the non-display area NAA where the static electricity discharge block 12 is located includes two corner areas where the static electricity discharge block 12 is arranged in a stepwise manner, and the arrangement space can be saved in the case of dispersing static electricity. In this embodiment, by setting the distance between the electrostatic discharge block 12 and the sub-pixel 13 to be greater than 0.5mm, it is possible to prevent electrostatic damage to the peripheral wiring 14 in the display panel, the peripheral wiring 14 including the cathode peripheral wiring and the anode peripheral wiring, the electrostatic discharge wiring 11 and the electrostatic discharge block 12 being arranged in the same layer as the peripheral wiring 14; the electrostatic discharge block 12 is located between the electrostatic discharge wire 11 and the peripheral wire 14. When the electrostatic discharge wire 11 and the electrostatic discharge block 12 are prepared, the electrostatic discharge wire 11 and the electrostatic discharge block 12 can be prepared by the same process as the peripheral wire 14, and an additional preparation process or a mask process is not required, so that the electrostatic discharge wire 11 and the electrostatic discharge block 12 are ensured to be simple in preparation process.

Wherein the cathode peripheral trace is for transmitting a cathode voltage to a cathode in the sub-pixel 13 and the anode peripheral trace is for transmitting an anode voltage to an anode in the sub-pixel 13.

That is, the plurality of static discharge blocks 12 are arranged in a manner of imitating the arrangement of the sub-pixels, so that on one hand, the static discharge blocks 12 can be prevented from being arranged too densely, static aggregation is caused, on the other hand, the static discharge blocks can be prevented from being arranged too dispersedly, and the excessive arrangement space is occupied, so that the frame of the display panel is widened, namely, the arrangement space occupied by the static discharge blocks 12 can be reduced under the condition of better static dispersion through optimizing the arrangement positions of the static discharge blocks 12, and the narrow frame of the display substrate is realized.

In some embodiments, the sub-pixels may include: a pixel circuit and a light emitting element connected to the pixel circuit.
