According to the film capacitive touch screen, all the conductive modules are finished on one surface of the transparent conductive base material, so that the structure of the film capacitive touch screen is simplified and the multi-point touch function of the film capacitive touch screen can be achieved.
Description
Technical field
The present invention relates to a kind of Film capacitive touch screen with bridging structure, belong to technical field of electronic equipment.
Background technology
Touch-screen is a kind of remarkable input equipment that improves man machine operation interface, have intuitively, simply, advantage efficiently.Touch-screen obtains a wide range of applications in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system etc.Touch-screen mainly contains following four classes, comprises resistance-type, condenser type, infrared and surface acoustic wave touch screen.Wherein, capacitive touch screen is owing to have excellent performance, such as, there is not the mechanical motion wear problem in the screen, even and simple in structure, transmittance is high, the linearity good, dustproof, fire prevention, scratch resistantly also have a stable performance etc. in worst environment, has become the main flow in market.And the sharpest edges of capacitive touch screen are that it has the multi-point touch function, have greatly improved operating characteristic and the result of use of electronic product.
At present, capacitive touch screen is divided into two classes, a kind of glass capacitive formula touch-screen, and another kind of is the Film capacitive touch screen.Because the many-sided advantage of Film capacitive touch screen, such as, make dirigibility, thin thickness, lightweight, cost advantage etc., its market share improves constantly.For the Film capacitive touch screen, existing implementation all is to adopt panel with the stickup of two-layer nesa coating and get.For this structure, its thickness aspect still can not satisfy design terminal to the pursuit of thickness, wishes two-layer nesa coating is reduced to the mode of one deck.In order to develop layer of transparent conducting film mode, the research worker adopts to design conductive structure on the two sides of transparent base, realizes the function of touch-screen.Carry out the design of conductive structure for the two sides of single layer of substrate material, in the use of reality, need to protect one of them face, it still can not satisfy the demand of simplification.
Summary of the invention
In view of above problem and demand, the object of the invention is to provide a Film capacitive touch screen with bridging structure.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of Film capacitive touch screen with bridging structure, this screen is comprised of panel, optical lens gelatin and conduction inductive layer with bridging structure from top to bottom, described conduction inductive layer comprise flexible and transparent base material, flexible and transparent substrate surface the figuratum nesa coating of tool, insulation course, bridge formation conductor wire, connect the plain conductor of nesa coating.
Described panel material is chemically reinforced glass or plastics.
Described panel lower surface exists decorative ink or vacuum coating.
Described insulation course is whole and covers or the local nesa coating that covers that it is to ensure that bridge formation conductor wire and nesa coating are electrically connected.
The bridge formation conductor wire live width of described bridge formation conductor wire is less than 15 μ m.
Beneficial effect of the present invention:
Capacitive touch screen of the present invention, all conductive modules all are to finish on a surface of electrically conducting transparent base material, have simplified the structure of Film capacitive touch screen, and can realize the multi-point touch function of capacitive touch screen.
