Description
Technical field
The present invention relates to a kind of capacitance touch screen, especially relating to can be only with a kind of simple integrated capacitor of one gold-tinted operation
Induction touch panel and preparation method thereof.
Background technology
Touch-screen, as a kind of novel human-computer interaction interface, is widely used on various digital information system, from small sized product
As mobile phone, digital product, arrive medium-sized product such as automatic navigator, panel computer, game machine, household electrical appliance, then to large-scale product
It can be seen that touch-screen product in product such as common query system, portable computer, Medical Instruments, market prospects are very considerable.This
Invention refers in particular to apply a kind of simple integrated capacitor sensing at smart mobile phone, panel computer, game machine, portable computer etc. to touch
Touch screen.
Existing a kind of tradition integrated capacitor induction touch panel (OGS), is a kind of bridging structure: in the non-visible area of touch-screen
Prepare color coating by silk-screen or gold-tinted technique；Fill and lead up the step of color coating and glass with OC glue or other transparent materials；Again
Plating ITO(tin indium oxide) prepare ITO pattern by gold-tinted technique after film；Then one layer of transparent insulation playing dielectric effect is covered
Film；Metal-coated membrane again, finally prepares metal bridge in gold-tinted technique.Make this structure OGS capacitive touch screen low temperature to be used
The adhesive force of coating technique, ito film and substrate is relatively weak, reliability is relatively poor.The making of this OGS capacitive touch screen
Needing five road gold-tinted operations, production process is complicated, technical difficulty is high, production cost is high, and the yields of product is relatively low.
Another kind of advanced OGS capacitance induction touch panel, is a kind of single-sided structure: at non-visible area silk-screen or the Huang of touch-screen
Light technique prepares color coating；Fill and lead up the step between color coating and glass with OC glue or other transparent materials；Plate ITO again
After film, the ITO electrode figure prepared by gold-tinted technique.Make this structure OGS capacitive touch screen also low temperature plated film skill to be used
Art.This OGS capacitive touch screen is more simpler than the making of traditional bridge structure OGS capacitive touch screen, but also needs to three roads
Gold-tinted operation, production process is relative complex, technical threshold is still very high, yields is relatively low.
In both the above OGS production method, it is also possible to the work preparing color coating at non-visible area silk-screen or gold-tinted technique
Sequence removes, directly the another side one layer of PET film with color coating of patch at glass substrate.But this structure is not strict meaning
OGS capacitive touch screen on think of, because this structure is " two panels " scheme.And, the hardness ratio of PET film is poor, compares appearance
Easily by metal or hard thing scratch, thus affect attractive in appearance and touch.
The feature of two kinds of above OGS structures will be coated with color coating in non-visible area, and exists between color coating and substrate
One very big step, step thicknesses is color diagram layer thickness.This height typically micron order (1.0～2.0 μm), and ITO
Film thickness is 15～30nm, and the step between both can make to rupture herein during deposition ito film.Therefore, this prepares two kinds of OGS
Structure will plate ito film after first this step being filled and led up again.And on color coating, deposit ito film be necessary for using low temperature plated film
Technology, this is the technological difficulties preparing OGS touch screen.Therefore, how to reduce during making OGS capacitive touch screen
Gold-tinted operation, the step problem walked around between color coating and substrate, avoid using a low temperature coating technique difficult problem, reduction technology multiple
Polygamy and raising product yield etc., be the problem that the present invention needs to solve.
The open a kind of integrated projection-type capacitive touch screen of Chinese patent CN101853115A and manufacture method thereof, its construction is only adopted
With one piece of substrate, the non-visual range on substrate is provided with color coating, is provided with and is provided with on the whole face of color coating on substrate
Bottoming dielectric film, bottoming dielectric film is provided with the first electrode pattern；First electrode pattern is provided with dielectric insulation film, electrolyte
Velum is provided with the second electrode pattern, and the coverage of electrolyte dielectric film does not include the splice terminal of the first electrode pattern；The
Two electrode patterns are provided with protection dielectric film, and the coverage of electric protection dielectric film does not include the first electrode pattern and the second electrode
The splice terminal of pattern edge；It is connected with external control circuit by connecting line in splice terminal.This invention is being provided with color coating
Monolithic substrate on use bottoming insulation film+ito thin film+dielectric insulation film+ito thin film+protection dielectric film MULTILAYER COMPOSITE
The thickness of touch-screen can significantly be compressed by membrane structure, improves frivolous property and yields.
