Background technology
In consumption electronic products market now, collect touch controllable function has turned into portable electric product main flow hair in display
The trend of exhibition.Contact panel has been applied to various electronic products, such as smart mobile phone (Smart Phone), panel computer
(Tablet PC), notebook computer (Notebook), navigator (Navigator), POS system, self-aided terminal (Self-
Service Terminals) and Medical Devices (Medical Equipment).Because user can be directed through on screen
The icon of display is operated and is assigned instruction, therefore contact panel provides the hommization behaviour between user and electronic product
Make interface.
Integrated capacitor formula touch screen (one glass solution, OGS) is a kind of common contact panel, relative to
Bilayer film formula (glass-film-film, GFF), double-layer and double-side formula (double ITO, DITO) etc., it is by touch control electrode
It is integrated on cover-plate glass, therefore reduces one piece of substrate, is conducive to lightening development trend.
But in OGS patterns, the first induction electrode tandem and the second induction electrode tandem usually be may be contained within into lid
The centre position on the surface of the same side of glass sheet, and ink barrier bed is arranged at the surrounding position on the same surface, by
When OCA fits with contact panel, the inner surface of contact panel is not smooth, i.e., described ink barrier bed and cover-plate glass it
Between there is segment difference, buffer status occur when being depressed into OCA at ink barrier bed with roller, cause OCA and there is segment difference
Cannot closely be attached completely between ink barrier bed, therefore bubble is had when contact panel inner surface coats OCA, even if through
Deaeration technique is crossed, still can cause deaeration not exclusively, have impact on the binding yield and display effect of touch control display apparatus.
On the other hand, the metal lead wire of first, second induction electrode tandem of connection is typically located at ink layer away from cover plate glass
The one side of glass.For example, Patent No. 201310181800.3, entitled " OGS capacitive touch screens and preparation method thereof " it is special
In capacitive touch screen disclosed in sharp application documents, it is that dielectric ink is first set on frame, reserves conductive hole, then with leading
Electric ink fills conductive hole, metal lead wire is finally made on dielectric ink, in this preparation method, due to dielectric ink and cover plate
The presence of segment difference between glass so that electrically conductive ink must be by the conductive hole and first, second induced electricity that are arranged on frame
Pole tandem connection, therefore the probability of metal lead wire open circuit or short circuit can be increased, yields is extremely low.
