At present, capacitance type touch control screen is mainly divided into two kinds of glass type (glass type) and diaphragm types (film type).The optics glue-line that two kinds of structures all fit to together by the touch-control sensing layer of outer field cover glass, internal layer and by both forms.Glass type touch screen structure is mainly that touch sensing is made in to ITO is on glass, and skin adds a slice cover glass, is called G/G(Glass-Glass) structure; as shown in Figure 1,1-tempered glass, 2-frame decorative layer; 3-OCA optics glue-line, 4-conducts electricity inductive layer, and 5-responds to glassy layer.Diaphragm type touch screen structure owner will be by ITO by photoetching or be printed on PET film; skin is cover glass,, as shown in Figure 2; 6-tempered glass; 7-frame decorative layer, 8-the one OCA optics glue-line, 9-first conducts electricity inductive layer; 10-the one Film rete; 11-the 2nd OCA optics glue-line, 12-second conducts electricity inductive layer, 13-the 2nd Film rete.In order effectively to reduce costs, meet the lightening market trend of terminal consumption electronic product simultaneously, nearly 2 years touch-control dealers again active development OGS technology, as shown in Figure 3,14-tempered glass layer, 15-frame decorative layer, 16-conducts electricity inductive layer.It is that inductive layer and cover glass are integrated on a slice glass substrate, not only can reduce glass or the film of inductive layer, also can save laminating processing procedure one, and this is simple in structure, frivolous, and light transmission is good; And owing to only having a slice glass substrate and having saved bonding process, be beneficial to and reduce production and assembly cost.
But, no matter be glass type, diaphragm type or OGS, the touch-screen of these structures, all be unable to do without the application of tempered glass.This tempered glass of industry personnel Yi Zhi is difficult to the quality that reaches stable in intensity, especially OGS technology, after sheet divides little sheet glass, because making the glass edge of original strengthening, cutting declines along intensity, must repair by chemical method the intensity on glass edge edge.It is very low that common this technology is produced yield, and there be limited evidence currently of has supplier to be ready to produce.In addition, because glass cannot be bending, so above-mentioned these technology all can not meet the market trend of current flexible bending.
Utility model content
The utility model uses tempered glass for solving existing touch-screen, and strength of glass is difficult to ensure, processing yield is low, and the technical matters that touch-screen cannot be bending simultaneously provides the flexible touch screen that a kind of intensity is good, pliability is good.
The utility model provides a kind of flexible touch screen, and described flexible touch screen comprises polyimide book rete and is positioned at the conduction inductive layer on polyimide film layer surface.
Preferably, between described polyimide book rete and conduction inductive layer, be provided with frame decorative layer.
Preferably, the thickness of described polyimide book rete is 0.2-0.3mm.
Preferably, described frame decorative layer is located at the edge of flexible touch screen, and described polyimide film layer comprises He Fei viewfinder area, viewfinder area, and described frame decorative layer covers the non-viewfinder area of polyimide film layer.
Preferably, described conduction inductive layer comprises the transparent inductive layer of the circuitous pattern that is used to form induction electrode, for the metal bridge formation line layer of the circuitous pattern of conducting X or Y-direction, between described metal bridge formation line layer and transparent inductive layer, is provided with insulation course.
Preferably, described flexible touch screen also comprises FPC, and described conduction inductive layer also comprises silver slurry line layer, and described silver slurry line layer connects transparent inductive layer and FPC.
Preferably, described conduction inductive layer also comprises protective seam, and described protective seam is covered in the surface of transparent inductive layer and silver slurry line layer.
The utility model also provides a kind of electronic product, and described electronic product comprises flexible touch screen described in the utility model.
Flexible touch screen of the present utility model, it is single-layer membrane structure, adopt polyimide book film as polyimide book rete simultaneously, not only can be bending, can also build bridge design (because this material self is high temperature resistant, meet the process warm ring of bridge formation processing procedure), flexible touch screen of the present utility model meets the lightening demand of product more, can meet the market trend of product curved surface simultaneously.Thereby reduction cost of products, improving product competitive power.
