Description
Technical field
The present invention relates to a kind of sensing structure and contact panel, relate in particular to a kind of a kind of individual layer touch-control sensing structure of a plurality of plane capacitances and touch-control display panel that uses described structure of on the individual layer conductive layer, forming.
Background technology
It is that military use develops that contact panel originates from seventies US military, and the eighties, technology was transferred to use among the people, and then developed into various purposes.(for example: input mode computing machine) is to be used as input interface with peripherals such as keyboard or mouses to the conditional electronic calculation element, yet the volume of these external input equipments is excessive not portable, causes one of electronic product slimming to hinder greatly easily.Because the demand of thinned electronic, contact panel also is subjected to consumer's favor gradually and shows up prominently at portable electronic product.In addition, contact panel is except being applied in individual portable information product, application also progressively extends to information household appliances, public information, communication facilities, office automation equipment, information collecting device, and field such as commercial unit, therefore the research and development of contact panel also becomes the center of gravity that electronic industry develops in recent years gradually.
In general, the principle of contact panel probably can be divided into two kinds of resistance-type and condenser types.Most of now Touch Screens all belong to resistance-type, at saturated polynary ester (polyethylene terephthalate, PET) between two transparent laminas of this class, insert the transparent conductive circuit plate of making by tin indium oxide (ITO), separate with small-sized pad (spacer) each other, be fixed on LCD (liquid crystal display, LCD) top of screen or other plotting units, when forming contact point, will note down the position of touching with finger presses.Though this technology is simple, but but still has following shortcoming: the first, electric resistance touch-control panel has double-layer structure, therefore still has certain thickness.The second, described technology also causes the screen wearing and tearing easily, if add the protection screen or reduce the coating of reflection, then can cause bad printing opacity.Three, hand shadow effect (hand-shadow effect) also makes the sensor misjudgment easily.
In order to solve the shortcoming of electric resistance touch-control panel, the technical research of capacitance type touch-control panel is also just shown up prominently gradually.Capacitance type touch-control panel generally is to plate indium oxide layer tin thin film and diaphragm on the clear glass surface.When the people did not contact with contact panel then, various electrodes were idiostatic, did not have electric current to pass through on contact panel has.When contacting with contact panel, the static inflow surface in the human body and produce weak current and pass through.Detecting electrode can be calculated position contacting according to the variation of current value.For example; As U.S. Pat .Pat.No.6,961,049 disclosed a kind of capacitive sensor structures 1, as shown in Figure 1.It mainly is to form sense line 11 on non-conductive substrate 10, and described sense line 11 is made of transparent tin indium oxide or other conductive materials.Then on sense line 11 forming one deck adhesion layer 12, on described adhesion layer, cover one deck non-conductive substrate 13 at last again.Described sense line 11 can produce electric field by the electronic signal that circuit link block 14 is provided.
Comprehensively above-mentioned, for problem that solves existing electric resistance touch-control panel and the thickness that reduces contact panel, therefore need a kind of individual layer touch-control sensing structure badly and use the touch-control display panel of described structure to solve the problem that existing electric resistance touch-control panel is produced.
