Conductive frame glue is prepared by adopting a one-off coating technology to replace a traditional dotting process technology, the width of the conductive frame glue is not limited by conduction point positions and can be subjected to narrowing adjustment, a design space of peripheral routing of the liquid crystal display panel can be enlarged, a narrow bezel visual effect of the liquid crystal display panel is greatly improved, badness caused by the fact that in the traditional dotting process, spinning occurs, and dotting is too large in the later period is avoided, and the product yield is greatly increased; by means of the one-off coating technology, sealing and conducting effects of the conductive frame glue are achieved, and time and manpower are saved; in addition, uniformly distributed conducting particles are arranged in the conductive frame glue, an upper substrate and a lower substrate are conducted, and meanwhile a supporting effect on the periphery of the panel is achieved; compared with the mode that in traditional panel frame glue, spacing pillars or separating balls need to be additionally arranged, the material cost is reduced.
Description
Technical field
The present invention relates to flat-panel screens field, particularly relate to the manufacture method of a kind of liquid crystal panel.
Background technology
As the outstanding person of flat faced display, Thin Film Transistor-LCD (Thin Film Transistor
Liquid Crystal Display, TFT-LCD) due to have low power consumption, excellent picture quality and
The performances such as higher production yield, the most gradually occupy the leading position in display field.Existing
Liquid crystal display major part on market is backlight liquid crystal indicator, it include display panels and
Backlight module.Generally display panels is by color film (Color Filter, CF) substrate, array (Array)
Substrate, the liquid crystal being sandwiched between color membrane substrates and array base palte and sealing frame glue (Sealant) composition.Liquid
Crystal display is by the electric field control to liquid crystal molecular orientation, changes the polarization state of light, and by partially
Tabula rasa realizes penetrating and stopping of light path, it is achieved the purpose of display.
As it was previously stated, in order to drive the liquid crystal between two pieces of substrates to deflect, current TFT-LCD mainly leads to
Cross conductive gold spacer and connect Array substrate and CF substrate, form conductive path.During actual application, it is to conduct electricity
Gold goal becomes conduction gold size to use with frame glue hybrid modulation, and this conduction gold size is mainly mixed with frame glue by gold goal
Form.Wherein, the gold goal used as conductive filler, internal layer is the spherical and resilient of uniform particle sizes
Macromolecular material, external sheath nickel (Ni), then by chemical plating method one layer of gold (Au) of Ni plated surface,
Or this sentences silver (Ag) layer and replace Ni layer and Au layer, form conducting particles.Above-mentioned Ni/Au (or Ag)
There are the following problems for the conductive gold spacer of cladding: 1) complex process；2) gold is noble metal, and price is costly；
3) gold salt used in gold plating process is cyanide mostly, and toxicity is the biggest；4) gold goal easily weighs line wounded
Road and cause short circuit.Thus, development technology is simple, abundant raw materials, cheap, eco-friendly
Novel conductive fillers, has the strongest Practical significance.
Meanwhile, the mode of conducting upper and lower base plate commonly used in the trade for TFT-LCD is, as it is shown in figure 1,
During panel design, fixing firing point position 110 is set in Array substrate 100 side, then, as in figure 2 it is shown,
At the conduction gold size 200 that firing point position 110 fixed point titration is mentioned above, to reach to turn on the mesh of upper and lower base plate
's.Such way benefit is that technique is simple, ripe, the most commonly used, and gold size consumption is few, fall
Low cost.But, the drawback of do so is the most prominent, first, uses the design of this firing point position, no
It is beneficial to plain conductor near TFT-LCD panel periphery frame glue dispensing area lay, because good in order to play
Turn-on effect, the size of firing point position 110 is typically designed to the coating beyond baseplate-laminating after-frame glue 300
More than width 500 μm, to ensure enough then areas and conduction, no matter do so allows for frame glue
How the width of 300 carries out constriction adjustment, and border effect all can be limited by firing point position 110 size,
The ultra-narrow border effect of present main flow cannot be realized；Secondly, there is the TFT-LCD face of firing point position design
Plate, generally when frame glue is coated with, carries out two procedures, and the most first coating forms main frame glue 300, then leading
Titration conduction gold size 200 on logical some position 110, the way of such two procedures, when wasting processing procedure greatly
Between, because the processing procedure of titration conduction gold size 200 would generally account for during more than half operation of frame rubber coating platform
Between, the most substantially；Finally, the mode at firing point position 110 titration conduction gold size 200 is used, to board
Precision and stability require the highest, as it is shown on figure 3, deviation somewhat all can cause after baseplate-laminating indivedual
Conduction gold size 200 is excessive, and generation conduction gold size 200 overflows line of cut or conduction gold size 200 stretches into viewing area
Problems such as (Active Area, AA), so bring rear end cutting to scrap, LCD alignment abnormal and good
The economic loss of the aspects such as rate is on the low side.
