The capacitive touch screen is high in light transmittance, low in costs of production processes, low in production difficulty and capable of avoiding yellow light processes.
Description
Technical field
The utility model belongs to the capacitance plate technical field, is specifically related to a kind of capacitive touch screen.
Background technology
Now, along with the development of electronics technology, keyboard or the mouse of mobile phone, digital camera, handheld device, vehicle-carrying DVD, MP3, instrument food etc. are substituted by capacitance plate gradually at present.The product of capacitance touch screen is not very burning hot several years ago, and along with people are more and more for the contact of touch screen product, thus nearly 2 years also slowly the more people of quilt accept even become custom.Shooting up of touch-screen not only evoked fiercer industry competition, also indirectly promoted the development of technology, and the mode of operation of its multi-point touch has risen to a new height to the influence power of touch-screen product especially, is also paid close attention to by people gradually.
Touch-screen mainly forms by touching detection part and touch screen controller, touch the front that detection part is installed in indicator screen, for detection of user touch location, send touch screen controller after the reception, and the Main Function of touch screen controller is to receive the information that touches from touch point detection device, and convert this information to contact coordinate, and give again CPU, its can receive the order that CPU sends simultaneously and be carried out.
In capacitive touch screen, projection-type capacitive touch screen is that current application is a kind of comparatively widely, have simple in structure, the transmittance high, the touch sensible parts of projection-type capacitive touch screen are generally a plurality of column electrodes and the row electrode is staggered to form the induction matrix.Usually the design that adopts comprises the two sides that column electrode and row electrode is separately positioned on same ambetti substrate, prevents from short circuit occurring at intervening portion; Or column electrode and row electrode be separately positioned on the two sides of same ambetti substrate, prevent from short circuit occurring at intervening portion.Also having a kind of is the homonymy that column electrode and row electrode is arranged on same ambetti substrate, be formed on the same conducting film, separate by the mode that insulation course and frame conducting bridge are set at column electrode and the staggered position of row electrode, column electrode and row electrode are separated and guarantee conducting on direction separately, can prevent effectively that it is in the intervening portion short circuit.
Adopt the capacitive touch screen of traditional design proposal can have the defective of the not high and poor work stability of transmittance, the capacitive touch screen transmittance of traditional design proposal is difficult to break through 80%.And during whole stressed flexural deformation, occur sharing at the interface easily, cause electrode to open circuit and touch inefficacy, touch sensible parts thereby easily damage.
Summary of the invention
Technical purpose of the present utility model is for the deficiencies in the prior art, provides a kind of transmittance height and sense of touch component life long ITO gap bridge capacitance plate.
The technical scheme that realizes the utility model technical purpose is: a kind of capacitive touch screen, described capacitance plate comprises the ambetti substrate, be laminated in capacitive function substrate on the described ambetti substrate by optical cement, and stack gradually in the ITO of capacitive function substrate and cross bridge electrode, the first insulation course, the ITO electrode, metal electrode and the second insulation course, described ITO electrode comprises that capacitance plate drives and induction electrode, described capacitance plate drives with induction electrode is separate and is arranged at same aspect, described ambetti substrate comprises viewfinder area and non-viewfinder area, described non-viewfinder area is distributed with black resin layer, described black resin layer also is provided with the wiring of metal electrode circuit, described ambetti substrate is provided with the bridging point, bridging point on the wiring of described black resin layer and the described ambetti substrate interconnects by the bridge joint mode, described ambetti layer also comprises the PET membrane structure spare of the two-layer ITO of being coated with conductive pattern layer and ag paste electrode, and two-layer described PET membrane structure spare and the described conductive pattern layer of one deck are bonded to each other by optical cement successively.
As the further optimization of technique scheme, the transmittance of described ambetti substrate is 98%.
As the further optimization of technique scheme, the thickness of described ambetti substrate is 0.25-0.38mm.
As the further optimization of technique scheme, described ambetti substrate is special-shaped tempered glass.
Compared with prior art, the beneficial effect main manifestations of a kind of capacitive touch screen of the utility model is: transmittance is higher, avoids the gold-tinted processing procedure, and the production technology cost is low, and production difficulty is lower.
In this manual combined and accompanying drawing that consist of the part of this instructions illustrates several aspect of the present utility model, and is used for explaining principle of the present utility model with its description.
