Abstract
The utility model discloses a touch-control capacitive sensing screen which comprises a glass substrate layer, a glass layer provided with an indium tin oxide (ITO) sensing electrode pattern and a liquid crystal display (LCD). A plastic film layer is adhered to the glass layer through a first optical clear adhesive (OCA) layer, the upper surface of the plastic film layer is adhered to the glass substrate layer through a second OCA layer, and an ink layer covers the surface, being contacted with the second OCA layer, of the plastic film layer, and is located at the edge area of the plastic film layer. Therefore, a display area is formed in the central area of the plastic film layer. By means of the touch-control capacitive sensing screen, less OCA layers are used, bubbles are prevented from being generated, and meanwhile light leakage rate is greatly reduced.
Description
Technical field
The utility model relates to a kind of touch control capacitance induction screen, relates in particular to a kind of mobile phone and shields with the touch control capacitance induction.
Background technology
Capacitive touch screen is four layers of compound glass screen; the inside 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 workplace; 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 current, 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 touch control capacitance induction screen, and this touch control capacitance induction screen has reduced the use amount of OCA optics glue-line, has avoided the generation of bubble; Simultaneously, also greatly reduce the light leak rate.
For achieving the above object, the technical solution adopted in the utility model is: a kind of touch control capacitance induction screen, comprise the glass-based flaggy, have the glassy layer and the LCD liquid crystal display of ITO sensing electrode figure, bonding by an OCA optics glue-line between described plastic film layers and the glassy layer, the upper surface of described plastic film layers is bonding by the 2nd OCA optics glue-line and glass-based flaggy;
Surface coverage one ink lay that described plastic film layers contacts with the 2nd OCA optics glue-line, this ink lay is positioned at the fringe region of plastic film layers, thereby forms the viewing area at described plastic film layers middle section.
Further improved technical scheme is as follows in the technique scheme:
In the such scheme, described plastic film layers is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The utility model touch control capacitance induction screen, bonding between its plastic film layers and the glassy layer by an OCA optics glue-line, the upper surface of described plastic film layers is bonding by the 2nd OCA optics glue-line and glass-based flaggy, surface coverage one ink lay that plastic film layers contacts with the 2nd OCA optics glue-line, this ink lay is positioned at the fringe region of plastic film layers, thereby form the viewing area at described plastic film layers middle section, thereby reduced the use amount of OCA optics glue-line, avoided the generation of bubble; Secondly, owing to the distance that has reduced between plastic film layers and the glass-based flaggy, thereby greatly reduce the light leak rate.
