Abstract
The invention relates to a wiring structure of an induction layer. The induction layer comprises a plurality of touch electrode groups which are longitudinally arranged, wherein each touch electrode group comprises two opposite touch electrodes; each touch electrode comprises a main body; the longitudinal width of each main body is reduced gradually from one end to the other end; and at least one bump is formed on the opposite edges of each main body and formed at the end with the smaller longitudinal width of each main body. The bump is formed at the end with the smaller longitudinal width of each touch electrode, so that an induction area is increased, and edge coordinates are easier to detect.
Description
Technical field
the present invention relates to a kind of wire structures of inductive layer, especially a kind of wire structures of individual layer inductive layer.
Background technology
along with scientific and technical development, touch-screen has replaced mechanical botton panel gradually becomes the new operation interfaces of electronic equipment such as mobile phone, notebook.Touch-screen comprises resistive touch screen, infrared touch panel, capacitive touch screen, and they obtain coordinate by different modes, and capacitive touch screen is due to its transmittance, sharpness and better reliability, and is applied in increasing product.
an important component part of capacitive touch screen is exactly inductive layer, existing capacitive touch screen generally includes two-layer inductive layer, a kind of mode is that the electrode in described inductive layer is diamond structure, two-layer inductive layer is layed in a side of glass plate by bridge joint, this kind of mode be complex process not only, and bridge joint place easily damages, product yield is low, causes cost to raise.Another kind of mode is that the electrode in described inductive layer is rectangle, is layed in respectively hyaline both sides, although this kind of mode can part technique, improves yield, due to employing still be double-deck design, so cost is still very high.
in order to comply with the market demand, reduce costs, people have invented individual layer inductive layer, described individual layer inductive layer comprises a plurality of touch-control electrode group longitudinal arrangements, each touch-control electrode group comprises two touch-control electrodes, the shape triangle of described touch-control electrode, and the relative touch-control electrode dextrorotation turnback described in another of touch-control electrode described in wherein, described in two, touch-control electrode forms described touch-control electrode group relatively.Although the wire structures of this individual layer inductive layer has solved Cost Problems, edge induction area is less, is difficult for detecting the coordinate at touch-control edge.So be necessary to provide a kind of wire structures of individual layer inductive layer of easy detection control edge coordinate.
Summary of the invention
technical matters to be solved by this invention is to provide a kind of wire structures of individual layer inductive layer of easy detection touch-control edge coordinate.
in order to address the above problem, the invention provides a kind of wire structures of inductive layer, described inductive layer comprises the touch-control electrode group of a plurality of longitudinal arrangements, described touch-control electrode group comprises two touch-control electrodes in opposite directions, described touch-control electrode comprises main body, the longitudinal width of described main body is reduced to the other end gradually by one end, and the edge in opposite directions of described main body is provided with at least one projection, and described projection is arranged at the longitudinal width compare little of described main body one end.
compared with prior art, touch-control electrode of the present invention is provided with projection in longitudinal width compare little one end, increases induction area, is more prone to Edge detected coordinate.
Accompanying drawing explanation
fig. 1 is the schematic diagram of inductive layer wire structures of the present invention.
fig. 2 is the decomposing schematic representation of inductive layer touch-control electrode group.
Embodiment
below in conjunction with drawings and Examples, the present invention is further illustrated.
please refer to Fig. 1 and Fig. 2, the wire structures of inductive layer involved in the present invention, described inductive layer comprises the touch-control electrode group 1 of a plurality of longitudinal arrangements, described touch-control electrode group 1 comprises two touch-control electrodes 20 in opposite directions, and relative another touch-control electrode 20 of one of them touch-control electrode 20 turns over turnback clockwise.The edge that in described touch-control electrode group 1, two touch-control electrodes 20 are relative is edge in opposite directions.
described touch-control electrode 20 comprises main body 10, and the longitudinal width L of described main body 10 is reduced to the other end gradually by one end, the figure that the shape of described main body 10 can be triangle, trapezoidal or other longitudinal width are successively decreased to the other end by one end.Described main body 10 arranges at least one projection 11, described projection 11 is outwards convexly equipped with from the edge in opposite directions of described main body 10, shape can be rectangle, semicircle or other irregular figures, described projection 11 is arranged at described main body 10 longitudinal width compare little one end, thus, just can increase the induction area of described touch-control electrode 20 longitudinal width L compare little positions, be more prone to detect.
be more preferably, described main body 10 is also provided with groove 12, and described groove 12 sets to the concave from described edge in opposite directions, is arranged at described main body 10 longitudinal width compare great one end, is symmetrical arranged with described projection 11, and quantity is identical.The shape of the shape of described groove 12 and described projection 11 is corresponding.Because two touch-control electrodes 20 in described touch-control electrode group 1 arrange in opposite directions, that is to say, the longitudinal width L of a touch-control electrode 20 in wherein said touch-control electrode group 1 is reduced to the other end gradually by one end, and the longitudinal width of another touch-control electrode 20 is increased to the other end gradually by one end so.Specifically, main body 10 longitudinal width L compare little one end of corresponding another touch-control electrode 20 in main body 10 longitudinal width L compare great one end of a touch-control electrode 20, therefore the groove 12 of a touch-control electrode 20 is accommodated the projection 11 of another touch-control electrode 20, described projection 11 stretches into the groove 12 of another touch-control electrode 20.By the projection 11 and the groove 12 that arrange in described main body 10, make to be more prone to the position of coordinates computed.
inductive layer wire structures of the present invention, by the longitudinal width L compare little one end at described touch-control electrode 20, projection 11 being set increases induction area, with this Edge detected coordinate; Moreover, by the longitudinal width L compare great one end at described touch-control electrode 20, groove 12 is set, make the position of easy coordinates computed.
