Background technology
Capacitive touch screen is than electromagnetic type, resistive touch screen, be applied on the mobile phone more and more widely, capacitive touch screen has the transmitance height, touches and needn't exert pressure, can resist the advantage of abominable external environment, survey when can also realize a plurality of touch point during work, therefore have a good application prospect.
Present capacitance plate on the market has two types basically, a kind of is two plane type, this touch-screen generally comprises overlay, sensing electrode substrate, sensing electrode layer etc., the sensing electrode layer is arranged on the sensing electrode substrate, and the sensing electrode layer comprises a plurality of along the first sensing electrode of first direction extension and the second sensing electrode that extends along second direction.Do not link to each other mutually between the first and second sensing electrodes, can change the electric capacity between the electrode in the time of operator's finger close or point touching screen, judge the coordinate that electric capacity changes by testing circuit, and then operate accordingly.Another is the one chip capacitance plate, and this touch-screen is arranged on the inboard of overlay with first, second sensing electrode, has saved the sensing electrode plate, has therefore realized purpose thinner, lighter, that more economize.The one chip capacitance plate comprises contact panel and adhesive substrates, contact panel is provided with transparent conductive film, this conductive film is generally made by nano indium tin metal oxide (ITO), and electrode unit is set on the conductive film, and electrode links to each other with the scanning chip of outside by cabling.
Traditional capacitance touch screen has that thickness is large, production process is many, the high in cost of production shortcoming, because the higher resistivity of ITO has limited the size at first direction and second direction top electrode, this causes the restriction on the touch-screen size simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of individual layer ITO mutual capacitance touchscreens of improvement, improvement by the electrode pattern structure, simplify touch-screen manufacturing process, reduce cost, reduce the thickness of screen, improve again sensitivity and the visual effect of capacitive touch screen, can effectively increase the size of touch-screen.
The utility model is achieved through the following technical solutions:
The individual layer ITO mutual capacitance touchscreens of improvement, comprise touch-screen, described touch-screen comprises substrate and is arranged on the sensing electrode layer of substrate inboard, the sensing electrode layer comprises conducting film, described conducting film comprises two electrode, diaphragm, glass mirror, metal routing, the flexible PCBs that are arranged in same layer, described distribution of electrodes is on diaphragm, and on electrode, electrode is connected with flexible PCB by metal routing glass mirror simultaneously by adhesive coverage; Described electrode is made by the ITO material;
Described two arrangement modes that are arranged in the electrode of same layer are: the concavo-convex bow font electrode that alternately extends is inlaid with square-shaped electrode in each groove of described bow font electrode, adjacent two bow font electrode mirror image symmetric offset spread.
Described two arrangement modes that are arranged in the electrode of same layer can also be: the parallel spiral fashion branched structure that spirals, and from about, one of the spiral fashion branched structure is connected with of adjacent spiral fashion branched structure all the time, the curl direction of adjacent two described spiral fashion branched structures is clockwise and counterclockwise alternative arrangement, and above structure is designated as helicoidal structure; From getting off, adjacent helicoidal structure is the mirror image symmetric offset spread.
The utlity model has following beneficial effect:
The utility model by the improvement of individual layer ITO mutual capacitance touchscreens graphic structure both simplified touch-screen manufacturing process, reduced cost, reduced the thickness of screen, sensitivity and the visual effect of capacitive touch screen have been improved again, can effectively increase the size of touch-screen, simultaneously since all ITO and metal wire all at same layer, need not bridge joint, therefore have simple in structurely, technique manufacturing process is simple, the characteristics that yields is high.
