Description
Technical field
The present invention relates to a kind of capacitance touch screen, especially relate to can be only with a kind of simple integrated capacitance induction touch panel of one gold-tinted operation and preparation method thereof.
Background technology
Touch-screen is as a kind of novel human-computer interaction interface, be widely used on the various digital information systems, from small sized product such as mobile phone, digital product,, arrive medium-sized product such as automatic navigator, panel computer, game machine, household electrical appliance, can see the touch-screen product again on large product such as common query system, portable computer, Medical Instruments, market outlook are very considerable.The present invention refers in particular to a kind of simple integrated capacitance induction touch panel that is applied in smart mobile phone, panel computer, game machine, portable computer etc.
The integrated capacitance induction touch panel of existing a kind of tradition (OGS) is a kind of bridging structure: the non-visible area at touch-screen prepares color coating with silk-screen or gold-tinted technology; Fill and lead up the step of color coating and glass with OC glue or other transparent material; Plate the ITO(tin indium oxide again) prepare the ITO figure with gold-tinted technology behind the film; Then cover the transparent insulating film that one deck plays the dielectric effect; Metal-coated membrane prepares metal bridge at last in gold-tinted technology again.Make this structure OGS capacitance touch screen and will use the low temperature coating technique, the adhesion of ITO film and substrate relative weak, reliability is relatively poor relatively.The making of this OGS capacitance touch screen needs five road gold-tinted operations, production process complexity, technical difficulty height, production cost height, and also yield of products is lower.
Another kind of advanced OGS capacitance induction touch panel, be a kind of single-sided structure: the non-visible area at touch-screen prepares color coating with silk-screen or gold-tinted technology; Fill and lead up step between color coating and the glass with OC glue or other transparent material; After plating the ITO film again, with the ITO electrode pattern of gold-tinted technology preparation.Make this structure OGS capacitance touch screen and also will use the low temperature coating technique.The making that this OGS capacitance touch screen is striden bridge construction OGS capacitance touch screen than tradition is simpler, but also needs three road gold-tinted operations, production process relative complex, technical threshold still very high, yields is also lower.
In above two kinds of OGS production methods, also can be removing with the operation that silk-screen or gold-tinted technology prepare color coating at non-visible area, directly the another side at glass substrate pastes the PET film that one deck has color coating.But this structure is not the strict meaning goes up the OGS capacitance touch screen, because this structure is " two " scheme.And the hardness ratio of PET film is relatively poor, than being easier to by metal or hard thing scratch, thereby influencing attractive in appearance and touches.
The characteristics of two kinds of above OGS structures all will be coated with color coating at non-visible area, and have a very big step between color coating and the substrate, and step thicknesses is the color diagram layer thickness.This is micron order (1.0～2.0 μ m) highly normally, and the ITO film thickness is 15～30nm, and the step between the two ruptures in the time of can making deposition ITO film herein.Therefore, two kinds of OGS structures of this preparation are plated the ITO film after all wanting earlier this step to be filled and led up again.And just must use the low temperature coating technique at color coating deposition ITO film, this is technological difficulties of preparation OGS touch-screen.Therefore, how reducing the gold-tinted operation in making OGS capacitance touch screen process, walk around step problem between color coating and the substrate, avoid using a low temperature coating technique difficult problem, reduce technical complexity and improve product yield etc., is the problem that the present invention need solve.
Chinese patent CN101853115A discloses a kind of integrated projection-type capacitive touch screen and manufacture method thereof, its structure only adopts a substrate, non-visual range on substrate is provided with color coating, be provided with whole of color coating at substrate and be provided with the bottoming dielectric film, the bottoming dielectric film is provided with first electrode pattern; First electrode pattern is provided with the dielectric insulation film, and the electrolyte velum is provided with second electrode pattern, and the coverage of electrolyte dielectric film does not comprise the splice terminal of first electrode pattern; Second electrode pattern is provided with the protection dielectric film, and the coverage of electric protection dielectric film does not comprise the splice terminal at first electrode pattern and the second electrode pattern edge; Be connected with external control circuit by connecting line on the splice terminal.This invention can significantly be compressed the thickness of touch-screen in the MULTILAYER COMPOSITE membrane structure of the monolithic substrate employing bottoming insulation film+ito thin film+dielectric insulation film+ito thin film+protection dielectric film that is provided with color coating, improves frivolous property and yields.
