Abstract
The utility model discloses a kind of capacitive touch screen, belong to projecting type capacitor formula touch screen technology field.This touch-screen is followed successively by substrate, optics adhesion layer and capacitive sensing layer from top to bottom; Capacitive sensing layer goes out patterned conductive layer by PET base material and surface thereof by the direct silk-screen of half tone and forms.A kind of capacitive touch screen of the present utility model is that base material passes through the direct silk-screen Nano silver conductive ink of half tone with PET, disposable realization induction, driving layer pattern and edge cabling.Eliminate the chemical etching process of typical thin films formula touch-screen and silk-screen or laser silver sizing process, simplification of flowsheet, reduce material cost, solve chemical reagent problem of environmental pollution in the production of diaphragm type touch-screen, too increase cover plate base material diversity, realize light, thin, the feature such as low cost, flexibility.
Description
Technical field
The utility model belongs to projecting type capacitor formula touch screen technology field, particularly a kind of capacitive touch screen.
Background technology
Along with the development of science and technology, touch-screen as one simply, man-machine interaction mode easily, be widely used in the every field of our daily life, such as mobile phone, media player, navigational system, digital camera, photo frame, PDA, game station, display, electrical equipment control, Medical Devices etc.Touch technology opens the new model of the interpersonal interactive operation of mobile terminal, and colorful, ultra-thin, low cost has become touch-screen industry inevitable development trend.
Be low cost, light, thin according to the demand of market demand touch-control products application.Current thin film formula touch-control product, mainly need carry out silk-screen acid-proof ink, and chemical etching and silk-screen silver slurry starch Radium art with silver, and processing flow is long, and fraction defective is higher, and material cost is high and etching can increase environmental pollution.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of without the need to chemical etching, production technology is simple, cost is low, pollution-free, low cost, flexible capacitive touch screen can be realized.
To achieve these goals, the utility model adopts following technical scheme:
A kind of capacitive touch screen, this touch-screen is followed successively by substrate, tack coat and capacitive sensing layer from top to bottom;
Described capacitive sensing layer forms by going out patterned conductive layer by PET base material and surface thereof by the direct silk-screen of half tone.
Described substrate is glass or other transparent flexible base materials.
Described substrate lower floor is also provided with decorative ink layer.
The mucilage materials that described adhesive linkage is water white transparency, light transmission rate is greater than 90%, plays levels adhesive attraction.Described flexible conducting material is attached to after on substrate, realizes induction at its lower surface, drives patterned conductive layer.
Described capacitive sensing layer is made up of PET and top surface conductive layers.
Described conductive layer is organic nano silver conductive ink material, and it is directly formed by silk-screen mode.
Adopting capacitive touch screen of the present utility model, is that base material is realized induction by the direct silk-screen Nano silver conductive ink of half tone, driven layer pattern with PET.Eliminate the chemical etching process of typical thin films formula touch-screen, simplification of flowsheet, reduce costs, solve diaphragm type touch-screen produce in chemical reagent problem of environmental pollution, too increase cover plate base material diversity, realize the features such as light, thin, low cost, flexibility.
Accompanying drawing explanation
Fig. 1 is a kind of capacitive touch screen structure schematic diagram of the utility model;
Fig. 2 is the patterned conductive layer of a kind of capacitive touch screen disclosed in the utility model embodiment.
Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
