Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Embodiment 1
Refering to fig. 1, the liquid crystal cell of the present embodiment includes array substrate 1, color membrane substrates 2 and is filled in array substrate 1 and coloured silk
Liquid crystal 3 between ilm substrate 2, and the columnar edge black matrix 10 set on liquid crystal cell edge, edge interception, side
The both ends of edge black matrix 10 abut array substrate 1 and color membrane substrates 2 respectively.
In addition, have columnar spacer in the middle part of liquid crystal cell, which includes having the primary divider 21 of segment difference and auxiliary
Spacer 22, primary divider 21 therein are in pressured state always, and auxiliary spacer 22 is used to that support to be added when external force is excessive
Effect, prevents 21 independent stress of primary divider and ruptures the damage for causing can not to restore.
Specifically, one end of the primary divider 21 of the present embodiment is fixed on color membrane substrates 2, when liquid crystal cell is completed
Afterwards, the other end of primary divider 21 is connected to 1 inner surface of array substrate.The width of primary divider 21 and auxiliary spacer 22 in liquid crystal cell
Spend and be spaced setting on direction, primary divider 21, auxiliary spacer 22 one end be fixed on color membrane substrates 2, and auxiliary spacer 22
Length is shorter than primary divider 21.Under normal circumstances, primary divider 21 plays the effect for maintaining box thickness, the free end of auxiliary spacer 22
Vacantly；When liquid crystal cell pressure increases, 21 compressive deformation of primary divider, auxiliary spacer 22 reaches deformation in primary divider 21
It is supported before the limit in 1 inner surface of array substrate.
Here, primary divider 21, the quantity of auxiliary spacer 22 are not restricted, and can be flexibly arranged as needed.
With the above arrangement, forming edge black matrix, primary divider and auxiliary spacer structures, edge on the color membrane substrates of the sides CF
Black matrix and spacer are made by predetermined pattern by 3D printing of solid powder material, primary divider therein, auxiliary interval
Object mainly plays a supportive role, and edge black matrix plays face plate edge interception, such BPS (Black Photo
Spacer, have both black matrix and spacer effect structure) technology because development etc. processing procedures margin (i.e. in the case where high temperature does not occur weigh
Power shows permitted amount of liquid crystal control range under uneven defect and low temperature bubble defect situation) it is wider, productivity is strong, because
The panel of this collocation COA technologies production, reliability are high.
Embodiment 2
It is a kind of embodiment of BPS technologies in embodiment 1, can be realized by time processing in the prior art more
Procedure, but the shaded effect between the adjacent pixel of the array substrate side of its collocation is by being stacked with into item between R/G/B
Shape region forms shading, and light-proofness is not so good as the black matrix of normal strip, the contrast for be easy to causeing panel declines.It is based on
This, the present embodiment has carried out further improvement to embodiment 1.
Such as Fig. 2, primary divider 21 and auxiliary spacer 22 stack setting on the thickness direction of liquid crystal cell, primary divider 21
One end is arranged on color membrane substrates 2, the area of the other end of primary divider 21 be more than auxiliary spacer 22 and with 22 shape of auxiliary spacer
At stage portion, primary divider 21 is lighttight black matrix, and primary divider 21 is integrally formed with auxiliary spacer 22.
By above-mentioned setting, edge black matrix, primary divider and auxiliary spacer structures are formed simultaneously on the color membrane substrates of the sides CF,
And primary divider is distributed in auxiliary spacer on black matrix grid lines, spacer has the function of black matrix simultaneously so that adjacent
Still there are black matrix shading, contrast to be obviously improved compared with embodiment 1 between each pixel, also, due to using 3D printing technique, saves
Exposure imaging is removed, the segment difference between edge black matrix and primary divider and auxiliary spacer need not develop simultaneously
At will not cause processing procedure margin is relatively narrow in developing process, uniformity is not easy to control, the trust sex expression of panel is imperfect to lack
It falls into.Such production method reduces the use of spacer material solvent and developer solution, more environmentally protective.
As Fig. 3 carries out modelling operability, (edge black matrix and spacer are made by target BPS patterns first when specifically making
Type) it is modeled by computer modeling software, it is converted to mathematical model；Then BPS to be printed is injected in 3D printer
(this processing procedure does not use the liquid of solvent dissolved state as BPS materials to material, because such material need to be through overexposure, development
The BPS patterns of target could be formed after equal processing procedures.), particularly, the present embodiment uses solid powdery BPS materials, and after printing
Effect with common processing procedure to ultimately reside in the material structure on substrate consistent；Then, 3D printer prints and completes BPS processing procedures,
It carries out continuing to produce in this way, the color membrane substrates that printing is completed flow into lower one of processing procedure, and the finally array substrate assembling of collocation COA
At finished product.Based on the large-sized glass substrate of advanced lines line, this 3D printer can be equipped with multiple printing heads, and according to setting
Program divide substrate regions to carry out collaboration printing, each region is independent of each other, and can greatly improve production efficiency.
The structure of the colored filter side of the COA technologies of this programme can manufacture completion by first procedure, eliminate
Traditional multiple tracks production process, has both saved cost, also improves production efficiency, meanwhile, product can be made to retain panel height
While contrast, moreover it is possible to overcome the insufficient production sex chromosome mosaicisms of homogeneity such as development, improve the reliability of product.
The above is only the specific implementation mode of the application, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as the protection domain of the application.
