Abstract
The invention discloses a capacitive touch screen, which comprises a substrate, wherein an indium tin oxides (ITO) layer is laid on the substrate; the ITO layer comprises a plurality of touch electrodes; and a touch electrode group is formed by inserting the two adjacent touch electrodes into each other. The touch electrodes are arranged on the ITO layer, so the aim of forming two layers of touch electrodes is fulfilled; the capacitive touch screen is simple in structure; the ITO layer is reduced; and the cost of the touch screen is reduced.
Description
Technical field
The present invention relates to a kind of touch-screen, especially a kind of capacitive touch screen.
Background technology
Along with science and technology development, touch-screen has replaced the mechanical type push button 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 because its transmittance, sharpness and better reliability, and is applied in the increasing product.
Existing capacitive touch screen, a kind of is to comprise substrate and two-layer ITO (Indium Tin Oxides, indium tin oxide), and the ITO layer is laid on the bilateral of substrate, and wherein an ITO layer is the X-axis detection layers, and another ITO layer is the Y-axis detection layers.Another kind of is the same side that two-layer ITO layer all is laid on substrate, for fear of the mutual conduction between the electrode, bridge contact is set on glass substrate.These two kinds of capacitive touch screens all need to lay two-layer ITO layer, complex structure, and cost is higher.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure and lower-cost capacitive touch screen.
In order to address the above problem, the invention provides a kind of capacitive touch screen, it comprises substrate, and described substrate is laid an ITO layer, and described ITO layer comprises a plurality of touch-control electrodes, and two adjacent described touch-control electrode pairs are inserted and are constituted touch-control electrode group.
Compared with prior art, capacitive touch screen of the present invention is provided with the touch-control electrode on an ITO layer, reach the purpose of two-layer touch-control electrode, and is simple in structure, and reduced the ITO layer, also reduced the cost of touch-screen.
Description of drawings
Fig. 1 is the structural representation of capacitive touch screen of the present invention.
Fig. 2 is the structural representation of capacitive touch screen ITO layer of the present invention.
Fig. 3 is the synoptic diagram of capacitive touch screen touch electrode of the present invention.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
See also Fig. 1 and Fig. 2; capacitive touch screen of the present invention comprises substrate 1, is layed in an ITO layer 2 of described substrate 1, covers the protective seam 3 and the touch-control chip 4 of described ITO layer 2; described ITO layer 2 comprises a plurality of identical touch-control electrodes 20, and described touch-control electrode 20 is connected to touch-control chip 4 by lead.Two adjacent described touch-control electrode pairs are inserted and are constituted touch-control electrode group 21, and described touch-control electrode group 21 is arranged in parallel successively.
See also Fig. 3, described touch-control electrode 20 comprise body 22 and and a plurality of fingers 23 of extending from body, described finger 23 is parallel to each other and quantity is three, but the quantity of described finger is not limited to three, also can be two or more.Described finger 23 is trapezoidal, long base and described body 22 adjacency in described trapezoidal finger 23.Have trapezoidal gaps 24 between the adjacent fingers 23 of described touch-control electrode 20, described gap 24 is identical with described finger 23 shapes.Constitute 20 pairs at the two adjacent touch-control electrodes of touch-control electrode group 21 when slotting, the gap 24 of another relative touch-control electrode 20 is stretched in the finger 23 of a touch-control electrode 20 in the described touch-control electrode group 21.
Compared with prior art, capacitive touch screen of the present invention arranges touch-control electrode 20 at an ITO layer, reaches the purpose of two-layer touch-control electrode, and is simple in structure, and reduced the ITO layer, also reduced the cost of touch-screen. And described touch-control electrode 20 has a plurality of fingers 23, determines easily the touch location of finger, and 20 pairs at two touch-control electrodes are inserted and consisted of touch-control electrode group 21, and matching is good.
