Abstract
The invention relates to a capacitive touch screen fitting method. The capacitive touch screen fitting method includes: cleaning protecting glass and sensing glass, coating optical cement on the inner side of the protecting glass, arranging the protecting glass with the optical cement and the sensing glass oppositely, fitting the protecting glass with the optical cement and the sensing glass under the environmental condition that atmospheric pressure is smaller than or equal to -98kPa, and defoaming. By the capacitive touch screen fitting method, air bubbles caused by ink level difference of the protecting glass during fitting are reduced, and reject ratio of the air bubbles is decreased.
Description
Technical field
The present invention relates to the applying method of capacitive touch screen.
Background technology
In whole capacitor formula touch-screen manufacturing process, back segment applying processing procedure, that is, the applying of cover glass and inductive layer glass or liquid crystal display module, main bad phenomenon has: bubble, dirty, foreign matter, skew etc.In bubble was bad, insoluble was because of the cover glass inboard, namely has a side of printing ink section difference, the bubble that its four limits printing ink section difference causes, and wherein printing ink section difference is at 10um～50um.Method at the bad general improvement of this bubble mainly contains:
1, vacuumizes the power of pumping by increase or improve the sealing of cavity, reach the purpose that improves applying chamber vacuum degree, and then fit;
2, under vacuum state, increase the applying time, but this measure is influential to production line line body production capacity;
3, ask optical cement manufacturer to adjust the prescription of glue, to increase the optical cement pliability, overcome the influence of printing ink section difference.
But by after the improvement of said method, bubble is bad to still have 2%～4%.
Be the bubble that the printing ink section difference that further reduces because of cover glass produces in the applying process, the present invention mainly changes the applying flow process and improves.
The attaching process of touch-screen is as follows at present:
The cleaning of inductive layer glass/cover glass==use the roller mode, with optical cement be attached at inductive layer glass==under the highest attained vacuum condition, with cover glass and inductive layer glass gluing==deaeration==inspection.Wherein the highest attained vacuum condition refers to that atmospheric pressure value is smaller or equal to the environmental baseline of-98kPa.When the inductive layer glass that has attached optical cement and cover glass are fitted, though under the highest attained vacuum environment, but because of the existence of cover glass printing ink section difference, printing ink section difference place air-flow can't be got rid of fully in the applying process, and the risk that produces bubble is arranged.
Summary of the invention
The applying method that the purpose of this invention is to provide a kind of capacitive touch screen, the generation of bubble in the applying process that causes for reducing the printing ink section difference because of cover glass, thus reduced the fraction defective of bubble.
For achieving the above object, the invention provides a kind of applying method of capacitive touch screen, this method comprises:
Cleaning cover glass and inductive layer glass;
Optical cement is attached to the inboard of cover glass;
With attached the cover glass of optical cement and inductive layer glass be arranged on mutually over against the position;
Under the environmental baseline of atmospheric pressure value smaller or equal to-98kPa, the cover glass and the inductive layer glass that have attached optical cement are fitted; And
Carrying out deaeration handles.
Beneficial effect of the present invention is by changing the attaching process flow process of touch-screen; optical cement preferentially is attached to the inboard of cover glass; to get rid of the bubble of the inboard printing ink section of cover glass difference position; post after optical cement do not have bubble at cover glass; carry out the applying with inductive layer glass again; adopt such attaching process flow process; control can be more prone to aspect the bubble generation; thereby reduced the possibility that bubble produces; make that bubble is bad is down to 1%～1.5% by original 2%～4%, it is unaffected to keep producing line line body production capacity simultaneously.
Preferably, use the roller attaching method, optical cement is attached to the inboard of cover glass, in order to better get rid of the bubble of printing ink section difference position.
Preferably, after deaeration is handled, check fraction defective, to the bad statistics of making of bubble, thus the difference before and after the change of contrast attaching process.
Description of drawings
Fig. 1 shows the installation drawing of the applying method of capacitive touch screen of the present invention.
Fig. 2 shows the applying process flow diagram of capacitive touch screen of the present invention.
Embodiment
With reference to the accompanying drawings the specific embodiment of the present invention is further described:
As shown in Figure 1, relate to cover glass 10 according to the applying method of the capacitive touch screen of embodiments of the present invention, optical cement 20, roller 30, inductive layer glass 40 and make-up machine 50, wherein make-up machine 50 comprises highest attained vacuum cavity 501.
When carrying out attaching process; according to applying method of the present invention; need cleaning cover glass 10 and inductive layer glass 40 earlier; shown in S01 among Fig. 2; after the cleaning; use roller 30 that optical cement 20 is attached to cover glass 10 inboards; shown in S02 among Fig. 2; the cover glass 10 that has attached optical cement 20 is positioned on the last jig platform of make-up machine 50; and inductive layer glass 40 is positioned on the lower clamp platform of make-up machine 50, shown in S03 among Fig. 2, afterwards can be in highest attained vacuum cavity 501; the cover glass 10 that has attached optical cement 20 is fitted with inductive layer glass 40; shown in S04 among Fig. 2, carry out deaeration after the applying and handle, shown in S05 among Fig. 2; check fraction defective at last, shown in S06 among Fig. 2.
The applying method of capacitive touch screen of the present invention compared with prior art; do not make any change for the laminated material that relates to; only be to use roller 30 attaching methods; optical cement 20 preferentially is attached at cover glass 10 inboards; to get rid of the bubble of cover glass 10 inboard printing ink section difference positions; after cover glass 10 posts optical cement 20 no bubbles; carry out the applying with inductive layer glass 40 again; be compared to and in the existing applying method optical cement 20 preferentially be attached at inductive layer glass 40; fit with the cover glass 10 that has printing ink section difference more afterwards; easier control aspect the bubble generation, thus the possibility that bubble produces reduced.Adopt the applying method of capacitive touch screen of the present invention can make that bubble is bad is down to 1%～1.5% by original 2%～4%, it is unaffected to keep producing line line body production capacity simultaneously, for production equipment, only need last jig platform and the lower clamp platform of make-up machine 50 are made small change, make the cost that drops into seldom just can obtain well to reduce the bad effect of bubble.
