Abstract
The utility model discloses a double-sided adhesive tape for a capacitive screen. The double-sided adhesive tape comprises a plastic thin film layer serving as a substrate, and a release material layer, wherein the plastic thin film layer is connected with the release material layer through an optical clear adhesive (OCA) layer in an adhesion way; and the surface, contacting a second OCA layer, of the plastic thin film layer is covered with a printing oil layer which is positioned in the marginal area of the plastic thin film layer, so that a display area is formed in the central area of the plastic thin film layer. According to the double-sided adhesive tape for the capacitive screen, the using amount of the OCA layers is reduced, the formation of bubbles is avoided, and in addition, the production efficiency and yield are also improved.
Description
Technical field
The utility model relates to a kind of mobile phone pad pasting, relates in particular to a kind of two-sided tape that is used for capacitance plate.
Background technology
Capacitive touch screen is four layers of compound glass screen; the inner surface of glass screen and interlayer respectively scribble one deck ITO, and outermost layer is a skim silicon soil glassivation, and interlayer ITO coating is as working face; draw four electrodes on four angles, internal layer ITO is that screen layer is to guarantee good working environment.When finger touch was on metal level, because people's bulk electric field, user and touch screen surface formed with a coupling capacitance, and for high frequency electric, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current divides the electrode on from touch-screen four jiaos and flows out, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos, and controller passes through the accurate Calculation to these four current ratios, draws touch point position.Form from the capacitive touch screen structure, its glass substrate occupies very big proportion; And during practical application, capacitance touch screen often all need embed in the corresponding electronic product, ink lay is to be printed on the glass-based flaggy in the existing capacitance touch screen, the thickness of ink lay that causes being positioned at the edge is thicker, and the OCA optics glue-line that the middle section that is positioned at ink lay needs should cost an arm and a leg with bonding middle section and the OCA optics glue-line that also needs to fill ink lay of lower floor, thereby cause OCA optical cement layer thickness thicker, and be easy to generate bubble, so cost has increased greatly; Secondly, the glass-based flaggy prints and adhesion technique simultaneously, is unfavorable for the raising of production efficiency and yield.Therefore how to reduce the use amount of OCA optics glue-line, avoid the generation of bubble, simultaneously, enhance productivity and yield, become the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides a kind of two-sided tape that is used for capacitance plate, and this two-sided tape that is used for capacitance plate has reduced the use amount of OCA optics glue-line, has avoided the generation of bubble; Simultaneously, also enhance productivity and yield.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two-sided tape that is used for capacitance plate, comprise a plastic film layers as base material, the first separated type material layer and the second separated type material layer, pass through one the one OCA optics glue-line bonding connection between the described plastic film layers lower surface and the first separated type material layer, surface coverage one ink lay that this plastic film layers contacts with an OCA optics glue-line, this ink lay is positioned at the fringe region of plastic film layers lower surface, thereby forms the viewing area at described plastic film layers middle section; Pass through one the 2nd OCA optics glue-line bonding connection between the described plastic film layers upper surface and the second separated type material layer.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, described plastic film layers is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
2. in the such scheme, the described first separated type material layer, the second separated type material layer are off-style paper layer or release rete.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The utility model is used for the two-sided tape of capacitance plate, and its ink lay is positioned at the fringe region of plastic film layers lower surface, thereby forms the viewing area at described plastic film layers middle section; Pass through one the 2nd OCA optics glue-line bonding connection between the described plastic film layers upper surface and the second separated type material layer, thereby reduced the use amount of OCA optics glue-line, avoided the generation of bubble, simultaneously, also enhance productivity and yield.
