Background technology

Touch-screen of the prior art mainly is divided into two kinds of resistive touch screen and capacitive touch screens.Resistive touch screen utilizes pressure sensitive to control.The major part of electric resistance touch screen is a resistance film screen that cooperates very much with display surface; This is a kind of laminated film of multilayer; It with one deck glass or duroplasts flat board as basic unit; The surface scribbles layer of transparent oxidized metal (transparent conductive resistance) conductive layer, is stamped one deck outside surface cure process, smooth anti-friction plastic layer, its inside surface above again and also scribbles one deck coating, between them, has the transparent isolating points of many tiny (less than 1/1000 inches) to separate insulation to two conductive layers.When the finger touch screen, two conductive layers has just had contact in the position, touch point, and resistance changes, and on X and Y both direction, produces signal, send touch screen controller then.Controller detects this contact and calculates that (mode according to analog mouse operates again for X, position Y).The most basic principle of Here it is resistive technologies touch-screen.

The common shortcoming of electric resistance touch screen is because the skin of laminated film adopts plastic material, and ignorant people too firmly or use sharp device to touch possibly to scratch whole touch screen and cause scrapping.But, within limit, only scratch and can injure outer conducting layer, it doesn't matter for five wire resistive touchscreen in the scuffing of outer conducting layer, and be fatal to the four-wire ohm touch-screen.

Capacitive touch screen (like IPHONE, IPAD screen etc.) is to utilize the induction by current of human body to carry out work.Capacitive touch screen is four layers of compound glass screen; The inside surface of glass screen and interlayer respectively scribble one deck ITO (nano indium tin metal oxide); Outermost layer is a skim silicon soil glassivation; Interlayer ITO coating is drawn four electrodes as workplace on four angles, internal layer ITO is that screen layer is to guarantee good working environment.When finger touch was on metal level, because the existence of people's bulk electric field, user and touch screen surface formed with a coupling capacitance, and for high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current flows out the electrode from four jiaos of touch-screen respectively, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos, and controller draws touch point position through the accurate Calculation to these four current ratios.

Capacitance plate uses electrode that human body is used as a capacitor element on principle, as conductor near and interlayer ITO workplace between when being coupled out the electric capacity of q.s appearance value, the electric current that flows away just enough causes the misoperation of capacitance plate.Therefore, when the larger area palm just possibly cause the misoperation of capacitance plate near capacitance plate rather than when touching, in wet weather, this situation is particularly serious.Not reaction when another shortcoming of capacitance plate touches with glove hand or hand-held nonconducting object, this is because increased the more medium of insulation.The anti-scratch of the outmost silicon soil of capacitance touch screen cover glass is fine; But be afraid of knocking of nail or hard thing; Pound out a duck eye and will injure interlayer ITO, no matter injure and injure inside surface ITO layer in interlayer ITO or the installation and transportation process, capacitance plate is with regard to cisco unity malfunction.

Owing to used capacitive touch screen on a lot of most advanced and sophisticated electronic equipments; Have above-mentioned many defectives of mentioning and touch, control capacitance plate with human finger, thus people begin to consider to design felt pen replace finger realize to capacitance plate touch, control.Granted publication number discloses a kind of capacitance pen for the Chinese utility model patent of CN202067238U on Dec 7th, 2011; This capacitance pen comprises columniform body; Described pen is provided with the aluminum ducted body of oxide layer as the surface, and described body front end is provided with the stainless steel lasso, is fixed with hemispherical nib on the lasso; Body front end tail end is provided with noose, is fixed with the plastics dop on the noose.Said structure constitutes effective electric conductor through nib, stainless steel lasso and aluminum ducted body; Utilize the bigger surface area of nib and flexible preferably can be very convenient, sensitive touch, control capacitance plate, but there is the bigger and attractive in appearance inadequately defective of cost in said structure because of having used the metal ducted body.
