Accompanying drawing explanation
Fig. 1 is the structural drawing of the touch panel described in the utility model embodiment;
Fig. 2 be touch panel described in the utility model embodiment optical anti-reflective film on etch the schematic top plan view of micro-pattern of formation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Touch panel described in the utility model embodiment, comprising:
Transparency carrier;
Be formed at the light-transmissive film layer with micro-pattern on described transparency carrier;
And touch pad electrode, is made on described transparent film layer;
Described light-transmissive film layer is for the shadow that disappears to described touch pad electrode.
The method being coated with the shadow layer that disappears of the prior art is changed into the light-transmissive film layer being formed on the transparent substrate and have micro-pattern by the touch panel described in the utility model embodiment, control its mist degree, diffusion, visual angle and hidden, realizing disappearing shadow to touch pad electrode better, and cast out of the prior art by SiO
2and Nb
2the shadow layer that disappears of O5 composition, simplifies technological process.During concrete enforcement, described light-transmissive film layer can adopt organic resin class material, also can be that SiO2 (silicon dioxide) or SiNO (silicon oxynitride) is as long as can meet printing opacity and can form micro-pattern thereon, enable the path changing light, thus the figure of the contact panel electrode on it is disappeared shadow, corresponding those skilled in the art can adopt coating, are coated with, light-transmissive film layer is formed on the transparent substrate by the techniques such as deposition, does not repeat them here.
Preferably, described micro-pattern is micro-pattern of regularly arranged geometric configuration, the disappear shadow effect of light-transmissive film layer to touch pad electrode now with this micro-pattern is better, it should be noted that micro-pattern also can be the pattern corresponding with contact panel electrode pattern, so more targetedly the pattern of touch control electrode is disappeared shadow.
Preferably, described micro-pattern is formed on described light-transmissive film layer by etching.It should be noted that, patterning processes can be adopted herein to pass through exposure imaging, pattern needed for rear formation is etched to transparent film layer, also can by making it softening to light-transmissive film layer heating, required pattern is formed, the technique that the material selection that those skilled in the art adopt according to light-transmissive film layer is suitable by impression.
Preferably, described light-transmissive film layer can be optical anti-reflective film layer, because more existing touch panels inherently have antireflection rete, therefore light-transmissive film layer can be optical anti-reflective film layer, antireflection rete makes micro-pattern, like this can Simplified flowsheet, cost-saving.
In the specific implementation, touch panel described in the utility model also comprises:
Ink frame, is formed at and has on the described light-transmissive film layer of micro-pattern, on the light-transmissive film layer that the method be coated with specifically can be adopted to be formed at by ink frame have micro-pattern.
In the specific implementation, touch panel described in the utility model also comprises:
Flatness layer, is formed at and is manufactured with on the described transparency carrier of described touch pad electrode, and the concrete mode of coating that can adopt forms flatness layer 35.
When practical operation, described touch pad electrode can be the touch pad electrode of ITO electrode or other type.
Preferably, described touch pad electrode can be ITO electrode, and described ITO electrode is made on described light-transmissive film layer in predetermined temperature range; Described predetermined temperature range is for being more than or equal to 200 degrees Celsius and being less than or equal to 250 degrees Celsius.
The embodiment of the preferred touch panel of the utility model adopts low temperature sputter ITO technique and antireflection rete namely can realize the shadow that disappears, reduce the requirement to ink frame high temperature resistance, and overcoming the problem of the shadow DeGrain that disappears still adopting traditional shadow layer that disappears to cause when adopting low temperature sputter ITO, when avoiding prior art high temperature, flatness layer holds caducous problem.
Preferably, described touch panel can be OGS capacitive touch panels, owing to importing low temperature (200 DEG C-250 DEG C) if the shadow layer that disappears that sputter ITO technique can cause silkworm chrysalis traditional is difficult to reach the effect that cannot see bridge point and ITO pattern for OGS capacitive touch panels, therefore now adopt the shadow effect that disappears during low temperature sputter ITO electrode better.But during practical operation, described touch panel also can be the touch panel of other type, is not limited to OGS capacitive touch panels.
