Abstract
The invention discloses a multiple-point capacitance touch screen of a flexible bridging structure. The multiple-point capacitance touch screen comprises a substrate, a first patterned conductive layer and a second patterned conductive layer, and the multiple-point capacitance touch screen belongs to the technical field of a projection-type capacitance touch screen. The touch screen sequentially includes the substrate, an optical transparent adhesive tape and a capacitance sensing layer; the substrate is composed of glass or other flexible base materials, and decorative inks on the lower surface; the capacitance sensing layer is formed by only adopting 5um conductive materials as a flexible bridging structure between the first patterned conductive layer and the second patterned conductive layer. In the capacitance sensing layer of the multiple-point capacitance touch screen, patterns at inducing or driving layers including adhesion layers can be realized by adopting an exposure and development process via the 5um conductive material, the complex structure of the OGC type touch screen is eliminated, the process is simplified, and the environmental pollution problem caused by secondarily strengthening hydrofluoric acid during OGC production can be solved, so that the touch screen is reduced in cost and can realize the characteristics of light weight, thinness, bending and multiple color.
Description
Technical field
The invention belongs to projecting type capacitor formula touch screen technology field, particularly a kind of multipoint capacitive touch screen making flexible bridging structure with ultra-thin materials.
Background technology
Along with the development of science and technology, touch-screen as one simply, man-machine interaction mode easily, be widely used in the every field of our daily life, such as mobile phone, media player, navigational system, digital camera, photo frame, PDA, game station, display, electrical equipment control, Medical Devices etc.Touch technology opens the new model of the interpersonal interactive operation of mobile terminal, and colorful, ultrathin flexible, low cost have become touch-screen industry inevitable development trend.
Touch-screen mainly contains following four classes, comprises resistance-type, condenser type, infrared and surface acoustic wave touch screen.Wherein, capacitive touch screen, owing to having excellent performance, such as, does not have mechanical motion wear problem in screen, even and if structure is simple, transmittance is high, the linearity is good, dust-proof, fire prevention, scratch resistantly also have 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 multi-point touch function, substantially increase operating characteristic and the result of use of electronic product.
According to structure, the demand of current multi-point touch control application is that structure is simple, light, thin, low cost.OGS technology is owing to saving a slice glass substrate and bonding process, and the advantage such as reduction production cost, thickness etc. that is beneficial to becomes the technology that numerous manufacturer competitively develops.But OGS formula contact panel adopts plating molybdenum aluminium or ITO to put up a bridge, owing to being subject to plated film temperatures involved, bridge formation substrate can not use flexible pet substrate, and filming equipment and die sinking expense cost high, in secondary hardening, hydrofluoric acid environment pollutes large, be difficult to do 2.5D structure, be difficult to realize flexible colouring.
Summary of the invention
In view of above-mentioned condition, be necessary to provide that a kind of thickness is thin, lightweight, cost is low, production technology is simple, pollution-free, the multipoint capacitive touch screen that can realize flexible colorful display.
To achieve these goals, the present invention adopts following technical scheme:
A kind of flexible bridging structure multipoint capacitive touch screen, this touch-screen is followed successively by substrate, Optical transparent adhesive and capacitive sensing layer from top to bottom;
Described induction structure bottom is nesa coating, it covers the flexible conducting material carrying adhesion layer, and flexible conducting material is formed the first patterned conductive layer, nesa coating configures the second patterned conductive layer for the first patterned conductive layer.
Described substrate is glass or other flexible parent metals.
Described substrate lower floor is also provided with decorative ink layer.
Described flexible conducting material carries adhesion layer and nesa coating adheres to, and this flexible conducting material only has 5um.
The upper surface of described flexible conducting material adopts exposure imaging technique to realize the first patterned conductive layer.
Described nesa coating upper surface covers one deck touch patterns conductive layer, relative to the first patterned conductive layer, is called the second patterned conductive layer.
Described flexible conducting material is as the flexibility bridging structured material of first and second pattern conductive interlayer.
Adopt capacitive touch screen of the present invention, the first patterned conductive layer is by only having the flexible conducting material of 5um and the second patterned conductive layer to overlap, and can save layer of transparent conducting film, therefore its thickness can reduce, and weight also reduces.What use is flexible conducting material simultaneously, and touch-screen can realize curve flexibility structure.
