Description
[technical field]
The invention relates to a kind of liquid crystal filling processing procedure, particularly a kind of employing drip mode (One drop filling, processing procedure under liquid crystal drop ODF).
[background technology]
Liquid crystal panel structure generally includes two glass substrates, is coated in the frame glue between these two glass substrates and is poured in this frame glue and two glass substrates are formed liquid crystal in the space.
The method that liquid crystal filling is gone in the space that this frame glue and two glass substrates form generally comprises two kinds.A kind of is injection method, that is: earlier frame glue is coated on the glass substrate, and one or more liquid crystal injection openings are set on this frame glue; Then another glass substrate is fitted with it, and the frame adhesive curing is made two glass substrate strong bonded; In vacuum environment, make liquid crystal inject opening contact liquid crystal again, cancel vacuum subsequently and make liquid crystal under the atmospheric pressure effect, inject the space of this liquid crystal panel.
Another kind of liquid crystal filling method is the mode of dripping, that is: earlier a complete frame glue is coated on the glass substrate of a horizontal positioned; With liquid crystal droplet separator (Dispenser) liquid crystal is distributed in the space that this frame glue and glass substrate formed; In vacuum environment, another glass substrate is fitted with it, and the frame adhesive curing is made two glass substrate strong bonded.
The prior art that the employing mode of dripping is carried out liquid crystal filling is an equipment under a kind of liquid crystal drop of being disclosed for the 5th, 511, No. 591 of United States Patent (USP) of bulletin on April 30th, 1996 as shown in Figure 1.Equipment comprises a vacuum chamber 8, a vacuum suction machine 9, a worktable 26 and a liquid crystal droplet separator 10 under this liquid crystal drop.This vacuum suction machine 9 is used to keep vacuum chamber 8 to be vacuum state, and this worktable 26 is arranged in the vacuum chamber 8 and can the X-Y direction in surface level moves, and this droplet separator 10 is fixed on the worktable 26.This droplet separator 10 comprises a kapillary 63, is used to make liquid crystal dropwise to drip.
Together with reference to Fig. 2, the method that adopts equipment under the above-mentioned liquid crystal drop to carry out liquid crystal filling may further comprise the steps: an infrabasal plate 23 that is coated with glue frame 24 is lain in a horizontal plane on the worktable 26 in the vacuum chamber 8 (step 31); The liquid crystal L that discharges predetermined volumes by this liquid crystal droplet separator 10 (step 33) to this infrabasal plate 23; One upper substrate 25 is pressed together on this infrabasal plate 23, and makes it sclerosis with fluorescent tube 26 these glue frames 24 of irradiation.
The employing mode of dripping is carried out liquid crystal filling, the diameter of kapillary 63 that can be by this liquid crystal droplet separator 10 of control and the quantity of liquid crystal drop is the liquid crystal L of the predetermined volume of the required release of control accurately, its more above-mentioned injection method is easy, can significantly save the time and the liquid crystal material of perfusion liquid crystal.
But, because equipment mainly adopts single liquid crystal droplet separator 10 to carry out under the liquid crystal drop under the above-mentioned liquid crystal drop, this kind mode has promptly determined total liquid crystal drop of liquid crystal panels of these liquid crystal droplet separator 10 perfusions to measure down by control device when the liquid crystal panel of a kind of specification of every instillation.In the time need pouring into to the liquid crystal panel of plurality of specifications, then this liquid crystal droplet separator 10 only can be earlier drips to a kind of liquid crystal panel of specification wherein, after this kind liquid crystal panel drips and finishes, need operating personnel to change the running parameter of this liquid crystal droplet separator 10, to carry out dripping of the twoth kind of liquid crystal panel, so, will elongate liquid crystal drop time significantly, unfavorable to output.
[summary of the invention]
Be the problem that processing procedure under the liquid crystal drop that overcomes prior art only can be simultaneously drips to a kind of liquid crystal panel of specification, the invention provides processing procedure under a kind of liquid crystal drop that can be simultaneously the plurality of specifications liquid crystal panel be dripped.
The technical scheme that technical solution problem of the present invention is adopted is: processing procedure under a kind of liquid crystal drop is provided, and it may further comprise the steps: the first liquid crystal droplet separator and the second liquid crystal droplet separator are provided; First infrabasal plate and second infrabasal plate are provided, and this first infrabasal plate is to should the first liquid crystal droplet separator, and this second infrabasal plate is to should the second liquid crystal droplet separator; The liquid crystal that discharges first volume by this first liquid crystal droplet separator discharges the liquid crystal of second volume to this second infrabasal plate by this second liquid crystal droplet separator to this first infrabasal plate.
Compared to prior art, because processing procedure can be simultaneously carries out under the liquid crystal drop the substrate of two kinds of specifications respectively under the liquid crystal drop of the present invention, when needing the liquid crystal panel of production plurality of specifications, can shorten the time under the liquid crystal drop significantly, perfusion when being fit to the plurality of specifications liquid crystal panel.
