Description
Technical field
The utility model belongs to the colored filter manufacture technology field, is specifically related to a kind of template that colored filter is used of making.
Background technology
Colored filter on the color membrane substrates is that LCD is realized the colored critical component that shows.Color filter making method commonly used at present comprises electrodeposition process, pigment dispersion method, ink-jet printing process etc.The pigment dispersion method is owing to becoming main flow at color characteristics, the precision of images and to having advantage aspect the patience of light, heat, and at its complicated technical process, prior art has the ink-jet printing process of employing to make colored filter to improve process efficiency.
As shown in Figure 1, it is on the substrate 1 that is being formed with black matrix 2 and barricade 3 that ink-jet printing process is made colored filter, forms red, green, blue pixel resin layer respectively in the mode of inkjet printing, removes barricade 3 at last, and this technology is simple.Wherein, the effect of barricade 3 is for the ink droplet overflow that prevents different colours (the ink droplet needs are excessive, and the solvent of inciting somebody to action wherein through heat treatment evaporates).
But in order to guarantee the planarization on colored filter surface, barricade 3 need be removed in the later stage, and too thick (height) that generally can not do is difficult to play and stops that drop flight goes into adjacent pixel regions and cause the effect of colour mixture.
In addition, the barricade 3 of prior art all is vertical with black matrix 2, and its bottom is less than the surface of black matrix 2, ink droplet can hang over barricade 3 surfaces or be piled up in the angle position of barricade 3 and black matrix 2, and be difficult for entering into pixel region, simultaneously, so also cause the waste of China ink.
The utility model content
The purpose of this utility model is the barricade effect not good (easily colour mixture, waste China ink) that solves prior art, can not reuse, need the problem of independent removal technology, provides a kind of colored filter to make the template of usefulness.
The technical scheme that solution the utility model technical problem adopts is a kind of template that colored filter is used of making, and described template is used for being arranged at substrate surface when substrate forms colored filter, and described template comprises:
Be used for blocking the occlusion part in the zone between the substrate pixel zone;
Be used for exposing the openwork part in substrate pixel zone.
Preferably, the shape of the shape of the occlusion part of described template and the black matrix on the substrate is complementary.
Preferably, the cross sectional shape of the occlusion part of described template is trapezoidal, and a described trapezoidal side near substrate is the bottom, is last base away from a side of substrate.
Further preferably, described trapezoidal be isosceles trapezoid.
Further preferably, described trapezoidal base angle angle is α, wherein 60 °＜α＜90 °.
Further preferably, described base angle angle [alpha], satisfied 70 °＜α＜80 °.
Preferably, the thickness of described template is 10 μ m-15 μ m.
Preferably, described template is prepared by crome metal.
Of the present utility modelly a kind ofly make the template that colored filter uses and have the following advantages:
1. template can be made when ink-jet printing process is made colored filter in advance, and with respect to the barricade that original position on substrate is made, the precision of template is higher, and can accurately control.
2. template is parts independently, and the colored filter that template can be used for a plurality of substrates is made, thus use template just need on each substrate, not make and remove barricade separately, therefore more convenient, efficient, improved the efficient of making; Simultaneously, after the ink-jet of a kind of pixel region in finishing red, green, blue pixel resin layer, can also directly template be removed, clean, guarantee when making the pixel resin layer of all the other two kinds of pixel regions, not occur colour mixture.
3. template more can stop drop flight to go into adjacent pixel regions and cause colour mixture with respect to traditional barricade, because above-mentioned template is to prepare separately, its thickness (highly) can be determined according to practical situations, so can be as the case may be suitable thickening (increasing) stops drop flight to go into adjacent pixel regions and cause colour mixture better.Since template thickening (increasing) more can effectively prevent the ink droplet overflow (it is excessive that ink droplet needs, through heat treatment will be wherein the solvent evaporation).
4. the shape of template and black matrix coupling that is to say and the consistent size of black matrix, does not have the angle position between template and the black matrix, and ink droplet directly enters the pixel region of below, has reduced black use amount like this.
