Description
Technical field
The invention belongs to touch screen technology field, particularly relate to a kind of capacitive touch screen glass panel and preparation method thereof.
Background technology
Capacitive touch screen has attaching type and one chip two kinds, is described below:
The capacitive touch screen of attaching type, stick a face glass (coverglass) by OCA optical cement on the induction glass (sensorglass) of capacitive touch screen, this face glass is only for the protection of capacitive touch screen, and wherein face glass (coverglass's) processing procedure is generally: section (glass substrate is cut into face glass)---sliver------chamfering---polishing---deeply---printing-ink to face glass edging; The processing procedure of induction glass (sensorglass) is generally: section (former of glass mother board is cut into glass substrate), and---------chamfering---slightly strengthens---plated film---photoetching---section (glass substrate is cut into required size)---sliver to edging to sliver.Then face glass (coverglass) and induction glass (sensorglass) are fitted; this kind of capacitive touch screen the surface of glass straight edge 2 between two, the surface chamfering of the chamfering 1 of face glass (coverglass) and induction glass (sensorglass) can form a strengthening layer c; as shown in Figure 1; effectively can protect capacitive touch screen; but in product today to miniaturization; this kind of touch-screen seems thicker, and volume is not preponderated.
The capacitive touch screen of one chip, be by the face glass of traditional capacitive touch screen (coverglass) and induction glass (sensorglass) two-in-one one design, by direct by conducting film plating on glass panels, on conducting film, manufacture figure needed for capacitive sensing, thus save a slice induction glass, improve transmitance, reduce costs; And sized rectangular glass substrate can be used directly to process, strengthen, plate conducting film, on conducting film, do figure needed for capacitive sensing, utilization factor and the efficiency of equipment can be improved, reduce costs.But one chip capacitive touch screen at present, maximum problem is, the intensity at its edge is very low, and after being assembled into finished parts terminal finished product, its edge is easily broken when being collided, and reduces global reliability.The main manufacturing procedure of existing one chip capacitive touch screen is:
Glass substrate cutting splitting, is shown in Fig. 2, cuts into former of the glass mother board that size is a*b the size that several sizes are the glass substrate of a1*b1;
Glass substrate edging also makes safe chamfering, sees Fig. 3 A and Fig. 3 B;
To glass substrate strengthening, see Fig. 4, make at double-sided glass and edge the strengthening layer that thickness is c (as about 10-50um) by ion-exchange;
Plate conducting film on the glass substrate and on conducting film, do the figure of several sizes of capacitive sensing needed for a11*b11, seeing Fig. 5;
By the undersized face glass with inductance capacitance image that glass substrate cuts, sliver becomes similar finished size, see Fig. 6;
To face glass chamfering, edging, throwing limit, final molding, see Fig. 7 A and Fig. 7 B.
This kind of one chip capacitive touch screen makes moderate progress relative to above-mentioned attaching type capacitive touch screen on thickness; but; as shown in Figure 8; because the face glass after cutting only has strengthening layer in bottom surface 3; and straight flange 2 between chamfering 1 and chamfering does not have strengthening layer; its limit intensity is very low, usually can carry out polishing to chamfering 1 and straight flange 2, and removal micro-crack improves its limit and obtains bending resistance, impact strength.But after all chamfering 1 and straight flange 2 do not have strengthening layer, throw chamfering, throw the raising edge strength that the method on limit can only be very limited.And from the material behavior angle of glass itself, glass is a kind of hard brittle material, its main cause of breaking is exactly micro-crack expansion, the growth at edge.In order to ensure glass use time safe reliability, be no matter for building, the physical toughened glass of automobile, furniture, for the chemically reinforced glass of electronic product, or the glass container used in daily life all needs to promote intensity on the edge of face glass.
In a word, above-mentioned two kinds of capacitive touch screens cannot the demand of more consistent thickness and safe reliability two aspect.
