Description of drawings
Fig. 1 is the layer structure schematic diagram of the touch sensor of first embodiment of the utility model.
Fig. 2 is the schematic diagram of the condenser type electric capacity touch-screen of first embodiment of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1-2, first embodiment of the utility model is a kind of condenser type electric capacity touch-screen, comprise touch sensor 10, described touch sensor 10 has layer structure, and layer structure is followed successively by substrate layer 101 from outside to inside, sclerosis increases attached coating 102, anti-reflection coating 103, OCA glue-line 104, an ITO layer 105, insulating blanket 106, the 2nd ITO layer 107; Described substrate layer 101 is plastic film, can certainly be sheet or plastic plate.In the present embodiment, described insulating blanket 106 is the PET film, or the PC film, or the PMMC film; Or described insulating blanket is the PET sheet, or the PC sheet, or the PMMC sheet.It is the wet coating of aliphatic polyurethane acryl resin that described sclerosis increases attached coating 102.Described anti-reflection coating 103 is the dried coating of organic-silicon-modified aliphatic polyurethane acryl resin.As an alternative, to increase attached coating 102 can be also the wet coating of silicon dioxide material or niobium pentaoxide material or magnesium fluoride in described sclerosis.As the replacement scheme of the present embodiment, can also be provided with protective coating between described OCA glue-line 104 and a described ITO layer 105, to prevent producing corrosion between 104 pairs of ITO layers 105 of OCA glue-line.As the another kind of replacement scheme to the present embodiment, described the 2nd ITO layer 107 also can be provided with protective coating away from the one side of insulating blanket 106.
