Description
Technical field
The present invention relates to display technology field, more particularly to a kind of system for dripping sour device, drop acid board and touching display screen
Make method.
Background technology
Liquid crystal panel industry is when making the touching display screen of On-cell techniques, in thin-film transistor array base-plate and coloured silk
Ilm substrate is completed liquid crystal panel (LCD) afterwards, it is necessary to make contact panel (Touch Panel, TP) again on color membrane substrates.
Overlapping skew is excessive with liquid crystal panel to avoid contact panel causes touch controllable function abnormal, therefore is making the first of contact panel
Need to be aligned by alignment mark (Alignment Mark) during road film.It is right in the liquid crystal panel of prior art such as Fig. 1
Position mark schematic diagram, at present make contact panel first of film when, it is necessary to first alignment mark 11 is carried out in liquid crystal panel,
So that contraposition uses during follow-up making touch control line pattern.
When using touch control lines of the traditional ITO (tin indium oxide) as contact panel, such as Fig. 2 is prior art in coloured silk
The structural representation of transparent ITO conductive layer is plated on the outside of ilm substrate, plated in the whole face in the outside of color membrane substrates 10 ITO conductive layer 40 it
Afterwards, because ITO conductive layer 40 is transparent, alignment mark 11 is still normal visible, and alignment mark 11 can provide in successive process
Normal contraposition.
But as On-cell technologies are progressively ripe, metalolic network (Metal mesh) substitutes traditional ITO conductive layer also therewith
.The metal conducting layer resistance of metalolic network framework is lower, conductive layer is thinner.It is prior art outside color membrane substrates such as Fig. 3
Side plates the structural representation of opaque metal conductive layer, and opaque metal conductive layer 50 is plated in the whole face in the outside of color membrane substrates 10
Afterwards, because metal is opaque, the alignment mark 11 pre-set in liquid crystal panel is covered by metal conducting layer 50, alignment mark 11
Normal contraposition can not be provided.Existing solution in the industry is one mask (Mask) of increase, to the increase of metal conducting layer 50 one
Road gold-tinted/etch process forms etch-hole 51, alignment mark 11 is displayed by etch-hole 51, such as Fig. 4, Fig. 4 is that Fig. 3 exists
Increase the structural representation after gold-tinted/etch process.But this processing procedure shortcoming is that cost is higher, gold-tinted/etch process production is influenceed
The cost of a mask need to be increased while energy.
The present inventor is before present inventive concept is proposed, it is also proposed that one kind drips sour device, as shown in figure 5, Fig. 5 is the present invention
The structural representation for the sour device of drop that people proposes in the early time.Acid-titrating head 104 is by way of syringe needle by acid droplet in metal conducting layer
On 50 surfaces, metal conducting layer 50 is etched to form etch-hole 51 by the acid drop dripped, makes to set in advance in liquid crystal panel
The alignment mark 11 put is displayed by etch-hole 51.
But find that acid droplet is on the metal surface of metal conducting layer 50, and as a result acid solution is direct in actual production process
Diffusion, acid solution diffusion phenomena will not be improved by changing acid drop size, and the acid drop less than 3mm occurs that etching is bad again.Analysis
The reason for drop acid diffusion is that when acid drop, only contact glass, liquid-solid boundary have surface tension, and acid drop surface is domed, is dripped by acid
Supported with the surface tension of glass contact point；But work as drop contact metal conducting layer 50, acid solution is generally 4 with the metal reaction time
~5min, contact point is without surface tension after reaction, therefore diffusion occurs, and dispersal direction is random, general to be finished toward first reaction
Breach diffusion.Effective display area domain (the Ative Area, i.e. figure on the periphery of acid solution scattering migration easy damaged alignment mark 11
Area) because alignment mark 11, from only 3.5mm or so with a distance from graph area, acid solution, which enters graph area, can cause product rejection.

11 can be cross alignment mark, and quantity can be multiple.Fig. 7 illustrates the present embodiment on a motherboard while made multiple
Touching display screen, it is in symmetrically to be provided with 6 alignment marks 11 altogether around the graph area 15 of each touching display screen.
After layer of metal conductive layer 50 are deposited on the outer surface in color membrane substrates 10, pre-production is formed in liquid crystal
Alignment mark 11 in panel is then covered by metal conducting layer 50.In order to by the use of alignment mark 11 as contraposition reference,
Metal conducting layer 50 is etched before making touch control electrode and driving electrodes, it is necessary first to show alignment mark 11
Come.It please join Fig. 9, the drop acid device that the present embodiment provides can then be contacted using sponge 108 with metal conducting layer 50, pass through sponge
Acid solution in 108 etches away the metal material of contact site, on metal conducting layer 50 formed etch-hole 51, etch-hole 51 with it is right
The position correspondence of mark 11, so that alignment mark 11 is displayed by etch-hole 51.Specifically, can be connected on acid-titrating head 104
There is drive mechanism (not shown), drive acid-titrating head 104 to move up and down by drive mechanism, the sponge 108 for exposing acid-titrating head 104 can
To contact or remove with metal conducting layer 50.
Wherein, the cross sectional shape of sponge 108 can be the shapes such as polygon, circle, ellipse.In the present embodiment, it is extra large
The cross sectional shape of silk floss 108 be rectangle, sponge 108 by three factors (length of rectangle, the width of rectangle, the length exposed) of setting,
To test influence of the size of sponge 108 to drop acid.Due to alignment mark 11, the size of itself typically only has 500um, therefore works as
The rectangular cross-section of sponge 108, a length of 3~8mm of rectangle, a width of 3~9mm of rectangle, when the length exposed is 1~10mm,
The center of sponge 108 offsets 1mm in the range of receiving relative to alignment mark 11, alignment mark 11 can be made to pass through etch-hole 51
Display, meet process requirements.
In one embodiment, sponge 108, which can also be, is movably mounted on acid-titrating head 104, the upper bottom of sponge 108
Put adjustable, make the exposed length of sponge 108 variable, you can to adjust the exposed length of sponge 108 as needed.Hand can be passed through
The exposed length of dynamic regulation sponge 108, a drive mechanism (not shown) can also be set in acid-titrating head 104, utilize the driving
Mechanism drives being stretched out or being retracted for sponge 108.
Acid solution used in drop acid includes nitric acid, phosphoric acid, acetic acid and water, and wherein nitric acid is mass ratio 1%~5%, phosphoric acid
For mass ratio 65%~75%, acetic acid is mass ratio 5%~15%, and surplus is water.
The sour device of drop provided in an embodiment of the present invention, is changed to sponge 108 by syringe needle, will drip sour mode at present and be changed to " seal
Formula ", acid measures control during drop acid, efficiently solves the sour diffusion problem of drop, improves product yield, and can be
Producing etch-hole 51 on the premise of without using light shield (mask) displays alignment mark 11, greatly reduces and is fabricated to
This.
[second embodiment]
Please join Figure 10, for second embodiment of the invention provide drop acid device, including motor 101, acid solution storage tank 102,
