Description
Technical field
The present invention relates to a kind of crystal liquid substrates to plate ito film pre-treating method.
Background technique
Liquid crystal display panel can carry out panel processing is thinned, obtain more preferably penetrance, more frivolous weight because of process requirements
Amount.Custom liquid crystals panel is after leading portion etch process, and entering film-plating process, (domestic mainstream plated film mode is splashed for vacuum
Plating), if supplied materials surface abnormalities (dirty, acidic residual, foreign matter adherency, electrostatic are excessive) easily cause, the plated ito film of film plating layer
Layer falls off, and causes product quality abnormal.And rear panel is thinned and contains acidic materials and OC foreign matter, cause subsequent ITO plated film demoulding.
So substrate surface process processing need to be carried out before crystal liquid substrate plates ito film.
Summary of the invention
The technical problems to be solved by the present invention are: providing one kind makes the more firm preceding place of crystal liquid substrate plating ito film
Reason method.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: crystal liquid substrate plates ito film pre-treatment side
Method the steps include:
Step 1: being blocked to the air hole between the two panels liquid-crystalline glasses of crystal liquid substrate with UV glue, and using ultraviolet
Linear light solidification；
Step 2: being cleaned with pure water to glass surface, multistage echelon cleaning way is taken, it is clear in level-one rinse bath
Wash water overflow discharge, the water of rear class rinsing bowl add to prime rinsing bowl final stage rinsing bowl supplement pure water；
Step 3: the glass substrate through over cleaning is put into plated film pretreatment liquid and impregnates 20-50min, pretreatment liquid
Ingredient including following weight percent: potassium hydroxide 10-15%；Ammonium nitrate 6-10%；Triethanolamine 7-12%；Polyaluminium
Aluminium 10-15%；Remaining is deionized water；
Step 4: the glass substrate that pretreatment liquid was impregnated is cleaned with pure water；
Step 5: the glass baseplate surface that pure water was cleaned dries up.
As a preferred solution, three-level echelon cleaning way is taken, the ejected wash water overflow discharge in level-one rinse bath,
The water of second level rinsing bowl adds to one-stage water wash slot, and the water of three-level rinsing bowl adds to second level rinsing bowl, three-level rinsing bowl supplement
Pure water.
The beneficial effects of the present invention are: this method is by effectively dropping glass cleaning and pretreatment liquid by alkaline processing liquid
Low glass surface acidity pH value, reduces the risk of product plated film rear demoulding.
Potassium hydroxide is for neutralizing product surface acidity pH value in pretreatment liquid；Aluminium polychloride is used for adsorption charge and work
With grain surface is referred to contrary sign ion, there is strong suction-operated at the position of contrary sign micelle or chain from molecular band heterocharge, by
Its Partial charge has been neutralized in this suction-operated, has reduced electrostatic repulsion, thus has been easy close and mutual with other particles
Absorption, keeps product coating process resistance smaller, plated film film layer is not easily disconnected from, and film resistance is smaller after plated film.
