Specific embodiment
In order to which those skilled in the art is made to more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model part
Embodiment, instead of all the embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under the premise of creative work, shall fall within the protection scope of the present invention.
The In-cell liquid crystal display panels provided below the utility model embodiment are introduced, as shown in Figure 1, Fig. 1
For the cross-section structure block diagram for the In-cell liquid crystal display panels that the utility model embodiment provides, the In-cell LCD display
Plate can include：
Glass cover-plate 1, polaroid 2, color membrane substrates 3, the wiring board 4 set gradually from top to bottom, wherein 1 He of glass cover-plate
Polaroid 2 is mutually bonded by optical cement.In addition, also there is the glass plate of 4 lower section of setting assist side and lower polarisation
Plate, but these structures and the current structure of display panel often used and indistinction, do not elaborate herein.
It is that touch layer is directly arranged on the lower section of glass cover-plate 1 and glass cover-plate 1 in Oncell liquid crystal display panels
It fits.In order to reduce the integral thickness of display panel, it is proposed that a kind of side for blending touch layer and color membrane substrates 3
Case, that is to say the full coating techniques of In-cell, and the In-cell liquid crystal display panels in the utility model are complete using In-cell
The display panel that coating technique obtains.
Therefore what is fitted with glass cover-plate 1 is polaroid 2, and during display panel use, it is easiest to adhere to
A large amount of electrostatic charges are exactly glass cover-plate 1, in the utility model by with glass cover-plate 1 the most close to polaroid 2 using having
There is the polaroid 2 of conducting function, while the wiring board 4 between color membrane substrates 3 and glass plate is connected by silver slurry layer 5, make polarisation
Piece 2 connects the earthed circuit of wiring board 4, so as to export electrostatic charge.In addition because silver slurry layer 5 can not influence display panel original
Some structures, therefore, silver slurry layer 5 can attach the edge setting of polaroid 2 and color membrane substrates 3.
At present, the more commonly used antistatic mode of usual display panel is to paste one on 1 surface of glass cover-plate of display panel
Layer electrostatic prevention film, is typically the film of conducting function, electrostatic charge is made to be attached on film, when follow-up display panel input makes
Used time, user can tear the film for having conducting function on display panel, then be attached to electrostatic charge on film also with
Take away, so as to eliminate the electrostatic charge generated during display screen is produced.
But in actual application, after the film on display panel is torn off, then subsequently come into operation in the process still
Electrostatic charge can be attached with.For example, for mobile terminal devices such as mobile phones, friction may occur due to the clothes with user and produce
Raw electrostatic, in addition, when air relatively dry, the electrostatic charge in air also can be relatively more, so as to cause on display panel
Adhere to excessive electrostatic charge.And similarly there is the hidden danger of breakdown display screen in these electrostatic charges.It is proposed in addition, also having in glass cover
The scheme of the surface plating high resistance film of plate 1, but this scheme is technically not perfect at present, and cost is high.
Therefore, it only needs simply to improve polaroid 2 in the utility model, makes it have electric conductivity, simultaneously
By silver paste in the prior art intersperse range carry out it is a degree of extend to form silver slurry layer 5, make polaroid 2 and wiring board 4
Ground wire is connected, and guides electrostatic charge.Entire scheme only does simple improvement on the basis of original, it will be able to reach good
Anti-static effect, it is simple in structure to be easily achieved, so as to realize the antistatic of display panel on a low-cost basis, improve aobvious
Show the service life and performance of panel.
Based on above-described embodiment, as shown in Fig. 2, Fig. 2 is the In-cell liquid crystal provided in another embodiment of the utility model

For 0.5%~2.0% solution, then by being coated with, spraying or impregnate the methods of be allowed to be attached to the surface of 2 layers of polaroid,
Anti-static coating is formed using room temperature or hot-air drying, that is to say conductive film layer 21.
Certainly, the substance using other conductive energy is also not precluded in the utility model as conductive coating.
This, does not enumerate.
In the utility model, there was only a kind of embodiment for 2 structure of polaroid with conducting function, in this reality
With in novel another specific embodiment, as shown in figure 3, Fig. 3 is the In-cell liquid crystal that another embodiment of the utility model provides
Display panel obtains cross-sectional view, as shown in figure 3, the polaroid 2 in the In-cell liquid crystal display panels can specifically wrap
It includes：
TAC (Triafol T) layer 231, PVA (polyvinyl alcohol) layer 232, lower TAC layer are set gradually from upper to small
233, PSA (pressure sensitive adhesive) layers 234.Therefore, in the present embodiment, psa layer 234 is colloid substance, can when producing psa layer 234
To add the antistatic substance of conductive energy in the raw material of pressure sensitive adhesive.So the psa layer 234 just it is conductive can,
The psa layer 234 is connected with silver slurry layer 5 simultaneously, it will be able to realize the export of electrostatic charge.
Further, the antistatic substance can be specifically derivative, quaternary ammonium salt, sulfuric acid ester, phosphate in the present embodiment
Or any one or more conductive materials in the derivative of polyethylene glycol.
Antistatic substance is added in the process of pressure sensitive adhesive, molding is reprocessed after first mechanical mixture.It is such with it is non-from
Based on subtype and macromolecule permanent type antistatic substance, anions and canons type can also add use in certain kinds.It is various anti-
Electrostatic substance molecule can assign the certain lubricity in pressure-sensitive adhesive material surface, reduce friction coefficient, inhibition and the production of minimizing electrostatic lotus
It is raw, while so that pressure sensitive adhesive is conductive.
It, can be by the mass ratio control of antistatic substance in psa layer 234 in order to not influence the performance pasted of psa layer 234
Make the 0.3%-3.0% in the gross mass of psa layer 234.Specific mass ratio can be 0.3%, 0.5%, 1.0%,
1.5%th, 2.0%, 2.5%, 3.0%.It should be noted that the ratio shared by the quality of antistatic substance in psa layer 234 is
The impedance of psa layer 234 is directly affected, it, specifically can leading according to psa layer 234 for the quality proportion of antistatic substance
The needs of electrical property and do corresponding adjustment.In order to which psa layer 234 is made to have good electric conductivity, the impedance of the psa layer 234 can
To be 1 × 108Ω~9 × 108Ω。
Based on above-mentioned any embodiment, in the utility model can by polaroid 2 by silver slurry layer 5 directly and wiring board 4
Earthed circuit connection, so that the electrostatic charge of display panel be eliminated, specifically, the wiring board 4 in the utility model
Flexible circuit board can be used.
