Description

A kind of capacitance plate refractive index matching film and preparation method thereof
Technical field
The present invention relates to a kind of touch screen technology field, more particularly to a kind of capacitance plate refractive index matching film.
Background technology
The touch screen induction technology of main flow, including resistance-type in the market, condenser type, infrared-type, Supersonic waves etc., Due to the requirement that consumer electronics are compact, infrared-type is mainly used in the electronic equipments such as middle large scale with Supersonic waves, takes Band property electronic product includes mobile phone and tablet PC etc., mainly based on resistance-type and condenser type.Before small-medium size is touched Screen mainly based on resistance-type, main reasons is that the technology more ripe, low production cost of resistance-type, and the amount of being applied to more Greatly, the consumption electronic products of low unit price, but after releasing with the mobile phone with projecting type capacitor formula touch-screen, whole situation has very Big change, has arrived now, and capacitive touch screen occupation rate has significantly surmounted resistance-type, becomes small-medium size portable electronic The main flow touching technique of product.
For in capacitive touch screen structure, it includes a sensing grid (sense array/sensing Arrangement), this grid is clipped between two glassivations, and usual outermost layer is overcoat, and its positioning principle is Determine the position of contact point using the change of the static electric field on sensing grid, when finger Touch screen, finger and An electric capacity is formed between grid, controller calculates the coordinate position of contact point using the variable quantity of grid electric parameter.
Capacitive touch screen is different from resistive touch screen, coordinates the functions such as multi-point touch, its upper and lower indium tin oxide electricity Polar curve road is to be covered with whole screen, in order to avoid indium tin oxide conductive film is scratched in process, affects the matter of display Amount, indium tin oxide conductive film (basement membrane is mainly PET film) before plated film all can do stiffened process to membrane surface, due to Indium tin oxide (ITO) refractive index height (about 2.0), its refractive index of the hard coat film of general stiffened low (about 1.5), then after etching Because ITO layer refractive index has differences with hard conating refractive index, each bed boundary interference differs ITO circuits, causes the ITO after etching Circuit easily manifests on screen, reduces the visuality of touch-screen.
