Preferably, described optical cement is OCA optical cement.

Wherein, described OCA optical cement is one of important raw and processed materials of touch-screen, is that optics acryl glue is made without base material, then at upper and lower bottom, the release film of one deck of respectively fitting again, is a kind of Double-face adhesive rubber alloy band without matrix material, and it is the best tackifier of touch screen.

Preferably, the edge of the tectal perforate of described perforate ink and inside casing, the perforate of perforate ink decorative layer and the edge of inside casing are toward extension 2mm to 3mm relatively.

Compared to existing technology, the beneficial effects of the utility model are:

The utility model mainly consists of two-layer organic polymer layers, non-friable and the resistance to bending of this organic polymer, institute is so that the durable degree of touch-screen is higher, and be coated with anti-scratch layer at the upper surface of the first organic polymer layers, guaranteed that touch-screen is not easy to be scratched, thus the serviceable life of greatly having improved touch-screen.

In addition, the edge of the tectal perforate of described perforate ink and inside casing, the perforate of perforate ink decorative layer and the edge of inside casing, toward extension 2mm to 3mm, contribute to reduce the difference in height at visible area and boundary place, ink shielded area so relatively, are beneficial to the climbing of ITO electro-conductive glass lead-in wire.
