Embodiment
Basic thought of the present utility model is: the battery lead plate of the novel projected capacitive touch screen of design and touch-screen, the ITO electrode cabling layout structure on the ITO battery lead plate is: at least one Channel connects at least two ITO Line.
Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme.
A kind of battery lead plate of capacitive touch screen, this battery lead plate are the ITO battery lead plate, and the ITO electrode cabling layout structure on this ITO battery lead plate is: at least one Channel connects at least two ITO Line.
Further, at least two described ITO lines whenever along the first direction setting are connected with a described Channel.
Further, the edge links to each other with a described Channel with at least two described ITO lines whenever that the second direction that described first direction intersects arranges, wherein, along the ITO line that is connected with different Channel of first direction setting and the ITO line that is connected with different Channel insulation mutually each other along the second direction setting.
The utility model is to adopt at least one Channel to connect at least two ITO Line; and prior art is to adopt every Channel to connect an ITO Line; as seen: adopt the utility model; article at least two, ITO Line can protect each other; that is: the wherein ITO Line that connects as every Channel goes wrong; make the ITO electrode one place take place when opening circuit; another ITO Line that enables the Channel connection immediately carries out circuit turn-on; that is to say; another still conducting of ITO Line; but this Channel operate as normal still then; touch-screen is also with regard to the energy operate as normal; thereby adopt this two I TO Line of protection each other, can guarantee the operate as normal of whole touch screen, improve the reliability of using touch-screen.
Be respectively the cabling layout structure synoptic diagram of ITO electrode of the present utility model as shown in Figure 1 and Figure 2.Wherein, the cabling layout structure of the ITO electrode of Fig. 1 is net-like pattern, the structure of contrast prior art Fig. 3, wide half area that is about existing ITO cabling of every ITO cabling.This of Fig. a kind of structure is applicable to multilayer ITO structure.The cabling layout structure of the ITO electrode of Fig. 2 is argyle design, the structure of contrast prior art Fig. 4, wide half area that is about existing ITO cabling of every ITO cabling.This of Fig. 2 kind of structure is applicable to individual layer ITO structure, and the cabling layout structure of ITO electrode of the present utility model can also adopt strip pattern, also is applicable to individual layer ITO structure, does not do and gives unnecessary details.
Concrete, the reticulate texture that is applicable to multilayer ITO structure adopts double-deck ITO film at least, the argyle design and the strip pattern that are applicable to individual layer ITO structure can manufacture individual layer ITO film, but the structure of which kind of type no matter, the ITO electrode that all need connect directions X or Y-direction in the bridging mode, two types structure cuts both ways, and is applicable to the reticulate texture of multilayer ITO structure, and the multilayer mode can reduce transmitance and complex process; Be applicable to argyle design and the strip pattern of individual layer ITO structure, technology is very simple comparatively speaking.
