Embodiment
The utility model has disclosed a kind of capacitive touch screen, as shown in Figure 1, comprises a transparent base 1, generally adopts glass.The upper surface of described base material is provided with two transparency electrode conductive layers, described transparency electrode conductive layer comprises X electrode 2 and Y electrode 4 respectively, each transparency electrode conductive layer is coupled to each other by lead by one group of electrode and forms, and connects the lead 3 and lead 5 space intersections that connect the Y electrode of X electrode.In conjunction with shown in Figure 2,, among first embodiment, between described two transparency electrode conductive layers, be printed with an insulating film layer 6 in order to make mutually insulated between two transparency electrode conductive layers.In the present embodiment, described insulating film layer 6 all covers the upper surface of whole X electrodes conduct layer, and Y electrodes conduct layer then is overlying on the upper surface of insulating film layer 6.
The material of described insulating film layer is by comprising epoxy system, carbolic acid system, and propylene system, the hybrid resin of vinyl, bubble disappear agent and solvent composition, its proportion is 40: 2: 58.Described insulating film layer thickness is generally 0.5～10 μ m.
The utility model has also disclosed a kind of manufacture method of capacitive touch screen, as shown in Figure 3, comprises the steps:
A) select a transparent base for use, at this substrate surface plating nesa coating;
B) etching nesa coating makes it to form one group of X electrode of arranging mutually;
C) at described transparent base surface printing one deck dielectric film;
D) adopt the solid operation of heating process and the UV light described dielectric film that hardens, under 150 ℃ drying condition, dry 5～15 minutes;
E) nesa coating is plated on the transparent base surface that has been covered with X electrode and dielectric film on above-mentioned surface;
