Currently, a liquid crystal display panel generally includes an upper substrate and a lower substrate, and a sealant is disposed between the two substrates; and an ITO layer is arranged on the inner side surface of each layer of substrate. In the existing display panel, due to the limitation of the internal space of the display panel, the conductive connection part between the lower-layer ITO and the upper-layer ITO can be overlapped with the sealing frame glue in the lamination direction, so that when an object with static electricity is close to the object, the sealing frame glue can be damaged by static electricity when the static electricity is released at the conductive connection part, and the sealing property of the sealing frame glue is affected.

In order to solve the above problems, the present application provides a liquid crystal display panel assembly, in which a conductive assembly electrically connected to a first conductive substrate and a second conductive substrate is staggered with a sealing sealant in a stacking direction, so that static electricity does not affect the sealing sealant when static electricity is discharged on the conductive assembly, and the sealing property of the sealing sealant is ensured.

Referring to fig. 1 and 2, a first aspect of the present application provides a liquid crystal display panel assembly, which includes a first conductive substrate 1, a sealing sealant 2 and a second conductive substrate 3 stacked from top to bottom; the first conductive substrate 1 is provided with a first conductive part 4 positioned outside the sealing frame glue 2, and the second conductive substrate 3 is provided with a second conductive part 5 corresponding to the first conductive part 4; the liquid crystal display panel assembly further comprises a conductive assembly 6 for electrically connecting the first conductive part 4 and the second conductive part 5; in the lamination direction, the projection of the conductive member 6 does not coincide with the projection of the seal paste 2.

The first conductive substrate 1 and the second conductive substrate 3 are connected together through the sealing frame glue 2, and the sealing frame glue 2 seals the periphery of the first conductive substrate 1 and the periphery of the second conductive substrate 3, so that the first conductive substrate 1 and the second conductive substrate 3 directly form a closed empty box; wherein the first conductive substrate 1 comprises a first substrate 101 and a first ITO layer 102 connected to the first substrate; the second conductive substrate 3 includes a second substrate 301 and a second ITO layer 302 connected to the second substrate 301; the structure is a conventional structure in the current liquid crystal display panel, wherein the ITO layer is a conductive film layer widely applied to various screens, and has good conductivity and transparency.

Specifically, the first ITO layer 102 includes a first conductive portion 4, the second ITO layer 302 includes a second conductive portion 5, and the second conductive portion 5 is one of display interfaces of the liquid crystal display panel assembly connected to an external device; the first conductive part 4 and the second conductive part 5 are electrically connected through the conductive component 6, so that conduction between the first ITO layer 102 and the second ITO layer 302 is realized; thus, the first conductive portion 4, the second conductive portion 5, and the conductive member form a conductive connection portion of the first conductive substrate 1 and the second conductive substrate 3.

In the lamination direction, the projection of the conductive component 6 is not overlapped with the projection of the sealing frame glue 2, namely, the conductive component 6 and the sealing frame glue 2 are staggered; the specific method is as follows: when the external electrostatic power source approaches the liquid crystal display panel, static electricity is discharged at the conductive connection part, that is, the static electricity is discharged between the first conductive part 4 and the second conductive part 5; and through staggering the conductive component 6 and the sealing frame glue 2, static electricity can not be released on the sealing frame glue 2, so that the sealing performance of the sealing frame glue 2 can not be affected.

The existing liquid crystal display panel is limited by the internal space structure, and the conductive component 6 and the sealing frame glue 2 are laminated, so that the conductive component 6 and the sealing frame glue 2 are overlapped, and when static electricity is released on the conductive component 6, the static electricity can hurt the sealing frame glue 2, thereby influencing the tightness of the sealing frame glue 2.

It can be understood that the sealing frame glue 2 is of a strip-shaped colloid structure enclosed between the first conductive substrate 1 and the second conductive substrate 3, in order to stagger the conductive assembly 6 and the sealing frame glue 2, the sealing frame glue 2 is provided with a avoidance part 7 for avoiding the conductive assembly 6, and the avoidance part 7 is a avoidance space formed on the sealing frame glue 2 and capable of avoiding the conductive assembly 6, so that the staggered arrangement of the sealing frame glue 2 and the conductive assembly 6 is further satisfied.

Here, the specific structural form of forming the avoidance portion 7 is not limited, so as to satisfy the requirement that avoidance can be formed for the conductive member 6; for example, referring to fig. 2, corners may be provided at positions of the sealing paste 2 near the conductive members 6 such that the sealing paste 2 is deviated from the conductive members 6 to form escape spaces; or, the sealing frame glue 2 is concaved at the position corresponding to the conductive component 6 to form a concave space capable of avoiding the conductive component 6.

According to the liquid crystal display panel assembly, the conductive assembly 6 for electrically connecting the first conductive substrate 1 and the second conductive substrate 3 and the sealing frame glue 2 are staggered in the stacking direction, so that when static electricity is discharged at the conductive connecting part, the static electricity does not influence the sealing frame glue 2, and the sealing property of the sealing frame glue 2 is ensured.

Referring to fig. 1, 4 and 5, in some embodiments, a hollow groove 8 exposing the second conductive portion 5 is formed on the first conductive substrate 1.

Specifically, the second conductive portion 5 is one of the display interfaces of the liquid crystal display panel assembly of the present application connected to an external device, and thus, it is necessary to expose the second conductive portion 5 to the outside for easy connection.

Referring to fig. 4, in the present application, in order to stagger the conductive component 6 and the sealing frame glue 2, the edge of the first conductive substrate 1 near the second conductive portion 5 is correspondingly flared, so that the outer edge of the first substrate 101 is near the outer edge of the second substrate 301, and the first conductive portion 4 can correspondingly extend towards the outside of the sealing frame glue 2, so as to facilitate the setting of the conductive component 6, thereby achieving the effect of staggering the conductive component 6 and the sealing frame glue 2.

The edge of the first conductive substrate 1 expands outwards to shield the second conductive portion 5, so that the second conductive portion 5 is exposed by correspondingly arranging the hollowed-out groove 8 on the first conductive substrate 1, and the connection between the second conductive portion 5 and the peripheral equipment is not affected.

Referring to fig. 1, 2 and 4, in some embodiments, the sealing sealant 2 includes a first frame strip 201, a second frame strip 202 extending along a length direction of the first conductive substrate 1, and a corner 303 connected between the first frame strip 201 and the second frame strip 202; the first conductive substrate 1 comprises a first substrate 101 and a first ITO layer 102 connected to the first substrate 101, wherein the first ITO layer comprises a first ITO main body 1021 positioned in the sealing frame glue 2 and a first conductive part 4 connected to the first ITO main body 1021; the first frame 201 is connected to the side of the first substrate 101, and the first frame 201 is spaced from the first ITO body 1021, the second frame 202 is flush with the side of the first ITO body 1021, and the second frame 202 is spaced from the conductive element 6.

Specifically, in order to stagger the conductive component 6 and the sealing frame glue 2, the first substrate 101 is arranged close to the edge of the second conductive part 5 in a spreading manner, and the first ITO layer 102 is unchanged; the sealant 2 needs to be adhered to the edge of the first substrate 101, which may result in too large a gap area between the first substrate 101 and the second substrate 301, and thus, dust may be easily deposited.

Referring to fig. 4, the second frame strip 202 is flush with the side edge of the first ITO body 1021, and the first conductive portion 4 protrudes out of the second frame strip 202; the first frame 201 needs to deviate from the second frame 202 to be connected to the side of the first substrate 101, so a corner 303 is correspondingly disposed between the first frame 201 and the second frame 202 to deviate the first frame 201 outwards, and therefore, a space is formed between the first frame 201 and the first ITO body 1021; by such a design, the first conductive portion 4 can protrude more beyond the second frame strip 202, so that the first conductive portion 4 has a sufficient width to arrange the conductive element 6, and further the second frame strip 202 is spaced from the conductive element 6.

By adopting the above technical scheme, the first substrate 101 is arranged in an outward expansion manner, so that the first frame 201 needs to deviate from the second frame 202 to be connected to the side of the first substrate 101, so that the first frame 201 is spaced from the first ITO main body 1021; the second frame strip 202 is flush with the side edge of the first ITO body 1021, so that the first conductive portion 4 can extend out of the second frame strip 202 more to have a sufficient width to arrange the conductive element 6, so as to satisfy the spaced arrangement between the conductive element 6 and the second frame strip 202.

Referring to fig. 1-4, in some embodiments, the conductive component 6 includes a plurality of conductive elements 601, and the conductive elements 601 are used to connect the first conductive portions 4 and the second conductive portions 5 at positions overlapping in the stacking direction.

Specifically, the conductive element 601 connects the first conductive portion 4 and the second conductive portion 5 at a position overlapping in the lamination direction, so that electrical connection of the first conductive portion 4 and the second conductive portion 5 can be achieved.

The conductive assembly 6 comprises a number of conductive elements 601, where a number refers to: the number of the conductive elements 601 may be one or more, so as to satisfy the electrical connection between the first conductive portion 4 and the second conductive portion 5.

In addition, the material shape of the conducting element 601 is not limited, and taking the material of the conducting element 601 as an example, the conducting element 601 may be made of conductive adhesive or other conductive connection materials; taking the shape of the conductive element 601 as an example, the conductive element 601 may be in a dot shape, a strip shape, or the like.

With continued reference to fig. 1-4, in some embodiments, the conductive assembly 6 includes at least two spaced apart conductive elements 601 to connect the first conductive portion 4 in parallel with the second conductive portion 5.

As can be appreciated, a plurality of conductive elements 601 are provided, each conductive element 601 being in conductive communication with the first conductive portion 4 and the second conductive portion 5 such that the first conductive portion 4 and the second conductive portion 5 form a parallel circuit; then, when external static electricity is discharged on the conductive component 6, even if one of the conductive elements 601 is knocked down, the conduction between the first conductive part 4 and the second conductive part 5 is not affected; only if the static electricity breaks down all the conductive elements 601, the conductive relation between the first conductive portion 4 and the second conductive portion 5 is destroyed, so that the anti-static capability can be greatly improved.

Here, the arrangement direction of the conductive element 601 is not limited so long as the first conductive portion 4 and the second conductive portion 5 are connected in series.

By adopting the above technical scheme, two or more conducting elements 601 are arranged, so that the first conducting part 4 and the second conducting part 5 form a parallel circuit, and when static electricity is released, even if one conducting element 601 is damaged, the conduction of the first conducting part 4 and the second conducting part 5 is not affected, and the antistatic capability is improved.

Referring to fig. 1 and 2, in some embodiments, the first conductive portions 4 are disposed along the first direction X and have a long strip shape, the second conductive portions 5 are correspondingly long strip-shaped and at least partially overlap with the first conductive portions 4 in the stacking direction, and the conductive elements 601 are arranged at intervals along the first direction X; the first direction X is a longitudinal direction of the first conductive substrate 1.

As can be appreciated, under the limitation of the internal structure of the liquid crystal display panel, the first conductive portion 4 and the second conductive portion 5 are expanded and arranged in a long strip shape along the first direction X (i.e., the length direction of the first conductive substrate 1), and then the conductive elements 601 are arranged at intervals along the first direction X; by such arrangement, the conductive area between the first conductive portion 4 and the second conductive portion 5 can be increased as much as possible, the number of the conductive elements 601 is increased, the electrostatic discharge path at the conductive connection portion can be further increased, and the antistatic capability is greatly improved.

By adopting the technical scheme, the first conductive part 4 and the second conductive part 5 are both in a strip shape along the first direction, and the conductive elements 601 are correspondingly distributed at intervals along the first direction; then, by expanding the first conductive portion 4 and the second conductive portion 5 along the first direction correspondingly, the conductive areas of the two portions can be increased.

And, the conductive element 601 is conductive adhesive.

In order to further improve the antistatic ability, the first conductive substrate 1 is provided with the convex portions 11 corresponding to the electric connection portions 10, and the discharge element 901 is connected to the electric connection portions 10 at positions where the convex portions 11 overlap in the lamination direction; it should be noted that, the discharge element 901 does not have a conducting function, and the discharge element 901 has only a certain performance of static dissipation; by arranging the discharging component 9, a certain consumption of static electricity can be carried out between the electric connection part 10 and the convex part 11, so that the static electricity has more discharging ways, the energy of the static electricity is consumed, and the discharging way of the static electricity is further increased.

The discharging assembly 9 includes a plurality of discharging elements 901, where a plurality means that the discharging elements 901 may be one or a plurality, so as to satisfy the performance of dissipating static electricity.

The discharge unit 9 is not overlapped with the seal frame 2 in the lamination direction, and thus the seal frame 2 can be prevented from being damaged by static electricity.

By adopting the technical scheme, the first conductive substrate 1 is provided with the convex part 11, and the discharge assembly 9 is arranged between the convex part 11 and the electric connection part 10, so that static electricity has one more release path; that is, static electricity can be dissipated in the electric connection portion 10 and the second conductive portion 5, so that a discharge path of the static electricity is further increased, and an antistatic capability of the liquid crystal display panel is improved.

As can be appreciated, under the limitation of the internal structure of the liquid crystal display panel, the electrical connection portion 10 and the protruding portion 11 are expanded along the first direction X and are arranged in a long strip shape (i.e., the length direction of the first conductive substrate 1), and then the discharge elements 901 are arranged at intervals along the first direction X; by providing such a configuration, the electrostatic consumption path between the second conductive portion 5 and the convex portion 11 can be increased as much as possible, and the antistatic ability can be improved.
