Technical background
The touch-screen of surface capacitance technology mainly is to adopt glass-base screen and molten slurry to starch the structure of protection screen with fixed attention at present; inside surface and interlayer face at the glass-base screen respectively scribble one deck ITO conductive layer; four limits of interlayer face are provided with silver slurry electronic circuit; silver slurry electronic circuit is connected with the ITO conductive layer of interlayer face, is coated with the molten slurry of one deck then in the above and starches protective seam with fixed attention.But can only reach Mohs 4H hardness because molten slurry is starched the hardness of protective seam with fixed attention, can't reach SiO
2Thereby if Mohs 7H hardness people process that touch-screen is operated in make finger or other hard things scratch molten slurry easily to starch protective seam with fixed attention and touch-screen is scratched easily and the lost of life that causes this touch-screen.
Summary of the invention
In order to solve the not problem of high easy scuffing of present surface capacitance type touch screen skin hardness; the invention provides a kind of surface capacitance type touch screen and manufacture method thereof of high rigidity anti-scratch; the capacitive touch screen of this high rigidity anti-scratch not only can conveniently be realized man-machine message exchange; can not scratch the problem that causes birthday noodle short easily simultaneously, and manufacture method is simple because of sealer produces inadequately firmly.
The present invention realizes by such mode: inside surface and interlayer face at the glass-base screen scribble the ITO conductive layer respectively, scribble one deck SiO in the ITO of interlayer face conductive layer outside simultaneously
2Protective seam, and at SiO
2Etching material is coated on four limits of protective seam, wherein SiO
2Protective seam is connected with ITO conductive layer seamless applying, the silver nitrate catalyzer of interpolation 3% and 5% Tetramethylammonium hydroxide in described etching material, and its manufacture method is will scribble ITO conductive layer, SiO earlier
2The touch-screen of protective seam and etching material was placed under 160 ℃～180 ℃ the hot conditions baking 50-60 minute, the touch-screen after will toast then take out through buck invade steep 3-5 minute after with flushing with clean water to remove the SiO of etching area
2Protective seam is removing SiO at last
2Printed silver slurry electronic circuit around the ITO conductive layer behind the protective seam.SiO
2Protective seam can effectively improve the hardness of touch screen operation face, can be with SiO and be added with the etching material of the Tetramethylammonium hydroxide of 3% silver nitrate catalyzer and 5%
2Removing of protective seam is because etching material is only brushed at SiO
2On four limits of protective seam, so it is only to remove the SiO of this printing zone
2Protective seam and do not damage following ITO conductive layer can not change and influence the performance of touch-screen, is removing SiO then
2Printed silver slurry electronic circuit around the ITO conductive layer behind the protective seam.
Advantage of the present invention is: the present invention can fall SiO on the ITO conductive layer by accurate etching
2Protective seam and can not destroy the ITO conductive layer is beneficial to printed silver slurry electronic circuit, SiO
2Protective seam can significantly improve the hardness and the anti-scratch performance of surface capacitance type touch screen, and product structure and manufacture method are all simpler, and cost is lower, meets industry high efficiency production requirement in enormous quantities.
