Description
Technical field
The utility model relates to electronic technology field, is specifically a kind of NEW TYPE OF COMPOSITE touch-screen.
Background technology
Touch-screen (touch screen) is also called " touch screen ", " contact panel ", it is a kind of induction type liquid crystal indicator receiving the input signals such as contact, when contacting the graphic button on screen, haptic feedback system on screen can drive various hookup mechanism according to the formula of programming in advance, in order to replace mechanical push button panel, and lively visual and sound effects can be produced by liquid crystal display picture.Touch-screen is as a kind of up-to-date computer input apparatus, and it is the simplest, convenient current, natural a kind of man-machine interaction mode.It giving multimedia with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.Be mainly used in the inquiry of public information, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate presell etc.
The basic unit of five line resistance technology touch-screens is all added in the voltage field of both direction on the conduction workplace of glass by precision resistance network, we simply can be interpreted as that the voltage field time-sharing work of both direction is added on same workplace, and outer nickel gold conductive layer only is only used for being used as pure conductor, the method having timesharing after touching to detect internal layer ITO contact point X-axis and Y-axis magnitude of voltage records the position of touch point.Five wire resistive touchscreen internal layer ITO need four lead-in wires, and skin only makes conductor only, and touch-screen obtains extension line and has 5.Its feature: resolution is high, high-speed transfer is reacted.Skin hardness is high, reduces scratch, scrapes and injure anti-chemical process.Still can use for 3,000 ten thousand times with point cantact.Electro-conductive glass is the medium of base material.Once correct, stability is high, never drifts about.Five wire resistive touchscreen have high price and the shortcoming high to environmental requirement.
Capacitive touch screen utilizes the electric current of human body to respond to carry out work.Capacitive touch screen is one piece of four layers of compound glass screen; the inside surface of glass screen and interlayer respectively scribble one deck ITO, and outermost layer is skim silicon soil glassivation, and interlayer ITO coating is as workplace; four electrodes are drawn at four angles, and internal layer ITO is that screen layer is to ensure good working environment.When finger touch on the metal layer time, due to human body electric field, user and touch screen surface are 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 divides and flows out from the electrode the corner of touch-screen, and the electric current flowing through these four electrodes is directly proportional to the distance of finger to corner, and controller passes through the accurate Calculation to these four current ratios, draws the position of touch point.
Because the mobile phone great majority of current trend all use capacitive touch screen, what it used is that the location contacts screens etc. such as human body realize capacitance variations.So just there will be, when second electrified body conductor is close to this type of touch-screen, also can cause the change of electric capacity, so the phenomenon that touch screen do not controlled just can be produced.
Utility model content
Problem to be solved in the utility model is to provide a kind of NEW TYPE OF COMPOSITE touch-screen easily controlled.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of NEW TYPE OF COMPOSITE touch-screen, it is characterized in that: comprise the first conductive layer and the second conductive layer, transparent insulation isolating points is provided with between described first conductive layer and the second conductive layer, the upper surface of described first conductive layer is provided with upper electrode line, the lower surface of described second conductive layer is provided with lower electrode line, the upper surface of described upper electrode line is disposed with the first insulating film layer from the bottom up, 3rd conductive layer, the lower surface of described lower electrode line is disposed with the second insulating film layer from top to bottom, laying, 4th conductive layer and bottom electrical polar curve.
Preferably, above-mentioned NEW TYPE OF COMPOSITE touch-screen, the upper surface of wherein said 3rd conductive layer is provided with protective seam, and described protective seam is prepared from by PET, and its thickness is 175um 188um.
