Description
Technical field
the utility model relates to the capacitive touch screen of new structure.
Background technology
the medium that touch-screen exchanges as a kind of man-machine close friend, is widely used in each electronic product at present.Such as mobile phone, computer, game machine, industry control, mp3 etc.
capacitive touch screen structure is complicated, and production process is more, and output capacity is lower.Producing yield low is the main bottleneck of present stage capacitive touch screen.Capacitive touch screen structure mainly contains GF, GFF, GG, OGS.Present stage on the market medium size based on GF, GFF.GF, relative to the thin one deck of GFF, more enjoys consumer to like.GF structure condenser type touch-screen is divided into two classes.One class is that driver circuit and induction line are all layered on FILM.This architecture technology difficulty is higher, and domestic is not also very prevailing.Another kind ofly be layered on glass cover-plate for induction line, driver circuit is layered on FILM.
current cover plate upper berth induction line yield is low is the principal element affecting a large amount of volume production of this framework.Non-visible area first spreads one deck black ink with cover plate, through plating ITO, copper facing, gold-tinted etching, circuit is being worked it out.It is poor that bad main cause is that black surround district and visible area intersection exist the section of about 6um to 15um, and the probability of broken string is very high.
Summary of the invention
the utility model object is: provide a kind of section of solution difference problem, improve the capacitive touch screen of the new structure producing yield.
the technical solution of the utility model is: a kind of capacitive touch screen of new structure, comprise glass baseplate, the second surface that described glass baseplate has first surface and is oppositely arranged with first surface, the mode of the second surface vacuum splashing and plating of described glass baseplate is coated with SiO2 black-out layer, the outside surface of described SiO2 black-out layer is provided with induction electrode layer, described induction electrode layer is formed through gold-tinted etch process by the ITO layer and metal conducting layer that are plated in SiO2 black-out layer outside surface, and the non-visible area spraying of described induction electrode layer is formed with ink layer.
because induction electrode layer is formed through gold-tinted etch process by the ITO layer and metal conducting layer that are plated in SiO2 black-out layer outside surface, therefore induction electrode layer has projection structure and the openwork part between projection structure, described projection structure is non-visible area, described openwork part is visible area, because etching is formed with multiple induction electrode in described visible area, the utility model only forms ink layer in the outside surface spraying of its projection structure.
above-mentioned SiO2 black-out layer plays a part bottoming and blanking, and bottoming is the adhesion promoting follow-up plating ITO, and blanking is the etching mark eliminating ITO.
preferably, described metal conducting layer is metallic copper or non-ferrous metal.Preferred, described metal conducting layer is metallic copper.
the utility model has the advantages that:
1, the first plated film of the utility model republishes ink logo, and overcome the first printing-ink pattern section difference problem that formed of plated film again, it is bad that the section of eliminating difference causes, and improves production yield.
, the utility model plating metal through PROCESS FOR TREATMENT, different colors can be presented, ink logo adopts the ink the same with metal color, and such product appearance just presents different colors, can meet different clients.
, SiO2 black-out layer in the utility model plays a part bottoming and blanking, bottoming is the adhesion promoting follow-up plating ITO, and blanking is the etching mark eliminating ITO.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is simple and easy schematic diagram of the present utility model.
wherein: 1 glass baseplate; 2 SiO2 black-out layer; 3 ITO layer; 4 metal conducting layers; 5 ink layeies; 6 induction electrodes.
Embodiment
embodiment: as shown in Figure 1, a kind of capacitive touch screen of new structure, comprise glass baseplate 1, the second surface that described glass baseplate 1 has first surface and is oppositely arranged with first surface, the mode of the second surface vacuum splashing and plating of described glass baseplate 1 is coated with SiO2 black-out layer 2, the outside surface of described SiO2 black-out layer 2 is provided with induction electrode layer 3, described induction electrode layer 3 is formed through gold-tinted etch process by the ITO layer 31 and metal conducting layer 32 that are plated in SiO2 black-out layer 2 outside surface, and the non-visible area spraying of described induction electrode layer 3 forms ink layer 4.
the implication of above-mentioned " the non-visible area spraying of induction electrode layer 3 forms ink layer 4 " is: because induction electrode layer 3 is formed through gold-tinted etch process by the ITO layer 31 and metal conducting layer 32 that are plated in SiO2 black-out layer 2 outside surface, therefore induction electrode layer 3 has projection structure and the openwork part between projection structure, described projection structure is non-visible area A, described openwork part is visible area B, because etching is formed with multiple induction electrode 6 in described visible area B, the utility model only forms ink layer in the outside surface spraying of its projection structure (non-visible area A).
in the present embodiment, described metal conducting layer 32 is preferably metallic copper, and thickness is 1-5um.
siO2 black-out layer 2 in the utility model plays a part bottoming and blanking, and bottoming is the adhesion promoting follow-up plating ITO, and blanking is the etching mark eliminating ITO.
the first plated film of the utility model republishes ink logo, and overcome the first printing-ink pattern section difference problem that formed of plated film again, it is bad that the section of eliminating difference causes, and improves production yield.
the metal of the utility model plating through PROCESS FOR TREATMENT, can present different colors, and ink logo adopts the ink the same with metal color, and such product appearance just presents different colors, can meet different clients.
below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
