Abstract
A capacitive touch screen comprises a substrate, and an ITO (indium tin oxide) layer is laid on the substrate, and comprises a plurality of touch control electrode groups. Since the touch control electrode groups are arranged on the ITO layer, the purpose for two layers of touch control electrodes is achieved, the structure is simple, moreover, the number of ITO layers is reduced, and the cost of the touch screen is reduced as well.
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 through 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 an X axle detection layers, and another ITO layer is a Y axle 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 be laid 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 present invention provides a kind of capacitive touch screen, and it comprises substrate, and said substrate is laid an ITO layer, and said ITO layer comprises a plurality of touch-control electrode groups.
Compared with prior art, capacitive touch screen of the present invention is provided with touch-control electrode group on 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.
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.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Please consult Fig. 1 and Fig. 2 in the lump; Capacitive touch screen of the present invention comprises substrate 1, be layed in said substrate 1 an ITO layer 2, cover the protective seam 3 and the touch-control chip 4 of said ITO layer 2; Said ITO layer 2 comprises the identical touch-control electrode group 20 of many groups; Said touch-control electrode group 20 is connected to touch-control chip 4 through lead, and said touch-control electrode group 20 is arranged in parallel successively.
Every group of rectangular touch electrode group 20 comprises two identical touch- control electrodes 22,23, said touch- control electrode 22,23 be shaped as right-angle triangle, and the shape of two right-angle triangles is identical and area equates.A touch-control electrode 22 relative another touch-control electrode 23 dextrorotation turnbacks wherein; Two said touch- control electrodes 22,23 are formed said touch-control electrode group 20 relatively; Said touch-control electrode group is approximately rectangle; Two hypotenuses of two said touch- control electrodes 22,23 are parallel relatively and leave the gap, promptly wherein the position of said touch-control electrode 22 relative broads corresponding to the position of another said touch-control electrode 23 relative narrower.
Compared with prior art, capacitive touch screen of the present invention is provided with two kinds of touch-control electrodes on 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.
The present invention is not limited to the foregoing description, and said touch- control electrode 22,23 also can be selected other shapes for use, and like the ditrigon that is shaped as of: said touch-control electrode, and the two triangle shape area of said ditrigon is identical.
