Abstract
A flexible bendable capacitive touch screen comprises a hard cover layer, a flexible transparent film layer, a colored decorating layer, a Nb2O5 film layer, a SiO2 film layer, an indium tin oxide (ITO) film layer and an insulation protection layer which are sequentially stacked. The capacitive touch screen has the advantages of being flexible, bendable, thin, light in weight, high in light-transmitting and low in chromaticity. Only the flexible transparent film layer is used, and no glass structures are used, so that a production process is simple, and a cost advantage is achieved. The flexible bendable capacitive touch screen is lighter, thinner and low in cost, performance level is not lowered, a large-area camber surface structure can be achieved, and infinite space is provided for appearance design of electronic products.
Description
Technical field
The utility model relates to a kind of touch-screen, relates in particular to a kind of capacitance touch screen of flexible.
Background technology
At present, the capacitance type touch-control panel that is applied as demand with the multipoint mode touch-control mainly is divided into two kinds of diaphragm type (film type) and glass types (glass type).These two kinds of structures are all formed by the touch-control sensing layer of outer field cover glass, internal layer and with the optics glue-line that both fit to together.At present the diaphragm type structure of main flow is by photoetching or be printed on the PET film with ITO; skin is called G/F/F (Glass-Film-Film) structure for cover glass; and the glass type structure of main flow is that touch sensing is made on the ito glass, and skin adds that a slice cover glass is to be G/G (Glass-Glass) structure.The former is subject to high price ito thin film material and grasps in minority Japanese trader hand, and latter G/G binding yield is generally on the low side, all is the main cause that causes the capacitive touch screen cost high.
In order effectively to reduce the touch-control module cost, satisfy the lightening market trend of terminal consumption electronic product simultaneously, nearly 2 years touch-control dealers actively set about research and development and reduce ito thin film or ito glass consumption, layout development TOL, embedded touch-screen.The TOL technology 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 the applying processing procedure one; be conducive to reduce production costs; improve the product yield; but the monolithic glass integral type capacitance plate of this TOL technology is because the restriction of the material of glass own and physical characteristics thereof; it is too thin that its thickness can not be done; otherwise can not reach client's impact strength requirement; this problem can only adopt the mode that increases thickness of glass to avoid usually; in case and thickness of glass has increased, thing followed problem is exactly the increase of weight; the decline of transmittance.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of capacitance touch screen of flexible is provided, it adopts one deck flexible and transparent film substrate, and the capacitance touch screen that can effectively solve glass structure can not be done problem too thin and that weight is big.
