Abstract
The invention relates to a touch screen structure with the 3D screen printing effect and the light guide effect. The touch screen structure with the 3D screen printing effect and the light guide effect sequentially comprises a protective layer, a polyester film layer and an ITO conductive film. A 3D wiredrawing decorative film layer is arranged on the position of a non-display area of a non-conductive face of the polyester film layer. A light-transmitting ink layer is arranged in the button position of the non-conductive face of the polyester film layer, and a light guide ink layer is arranged in the button position of the conductive face of the polyester film layer. According to the touch screen, ink does not need to be printed on the outermost protective layer in a silk screen mold, limitations of a panel adopted for the protective layer are reduced, and the touch screen structure can have the advantages of being rich and colorful in appearance and high in flexibility of appearance design. A light guide panel does not need to be arranged on a button area, and thus the thickness of the product can be further reduced. The decorative film layer is arranged below the protective layer, and thus the appearance of the product can not be affected after the product is used for a long time. The screen printing yield is relatively high, and compared with a touch screen panel requiring that buttons have the light guide effect, the touch screen structure with the 3D screen printing effect and the light guide effect is simple in manufacturing process and high in yield.
Description
Technical field
The present invention relates to a kind of touch screen structure, more particularly, relate to the touch screen structure of a kind of 3D of having silk-screen effect and light guide effect.
Background technology
The touch screen of prior art adopts glass, PMMA(polymethylmethacrylate, i.e. acrylic) or other composite plate material, be difficult in its surface form the decorating surface film of 3D wire-drawing effect.And conventionally need to be on the protective seam of touch screen ink for screen printing, adopt this technical scheme silk-screen yield lower.
The touch-screen of prior art, if require there is light guide effect in key zone, a slice light guide plate of must fitting under button, the present invention is many relatively fit together processing procedure and cross cutting processing procedure.As Chinese utility model 201220053999.2, the full bonding structure of a kind of handset touch panel and LCM is disclosed, comprise touch-screen, LCM and the optical clear double faced adhesive tape that touch-screen and LCM are fitted as a whole, the periphery silk-screen of touch screen plane has black out ink, and the black out ink hollow out that is positioned at touch-screen bottom forms Touch control key character; The LCM framework exterior domain of LCM below is provided with the FPC that is connected and is powered by main circuit board with mobile phone main circuit board, above FPC, be provided with LED lamp, above LED lamp, be provided with light guide film module, make light be directed into LCM framework Nei region, LCD display below by the LED lamp of light guide film module below, the region that the light that LED lamp sends is directed at touching character 1 equably makes touching character printing opacity.The light guiding film that described light guide film module is made by transparent material and the upper anti-dazzling screen, the lower shading that are covered in respectively above described light guiding film and below described light guiding film form.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of process rate compare Gao, key zone not need to establish light guide plate, can further dwindle the touch screen structure with 3D silk-screen effect and light guide effect of product thickness.
Technical scheme of the present invention is as follows:
A touch screen structure with 3D silk-screen effect and light guide effect, comprises protective seam, laminated polyester film, ITO conducting film successively, is provided with 3D wire drawing decorative film layer on the position of the non-display area on the nonconductive surface of laminated polyester film; On key position on the nonconductive surface of laminated polyester film, be provided with printing opacity ink layer, on the key position on the conducting surface of laminated polyester film, be provided with light guide ink layer.
As preferably, on the conducting surface of ITO conducting film, be provided with the electrode pattern layer with touch-control sensing function.
As preferably, between protective seam and decoration coating, be provided with optics glue-line.
As preferably, between laminated polyester film and ITO conducting film, be provided with optics glue-line.
As preferably, electrode pattern layer is also provided with laminated polyester film behind.
As preferably, decoration coating is at key position for hugging hollow structure, and printing opacity ink layer covers the hollow structure of hugging of key position.
Beneficial effect of the present invention is as follows:
Touch-screen of the present invention is guaranteeing, on the basis of touch screen function, to have realized following advantage:
1, touch-screen of the present invention, need to be on outermost protective seam ink for screen printing, the panel that protective seam is adopted restriction reduces, and can realize outward appearance rich and varied, appearance design dirigibility is high;
2, key zone does not need to establish light guide plate, can further dwindle product thickness;
3, decoration coating is arranged on protective seam below, can use for a long time and does not affect product appearance;
4, silk-screen yield is relatively high, and relatively requires button to have the touch screen panel of light guide effect, and processing procedure is simple, and yield is higher.
