Position:One: Resistor film technology
Principle of resistor film technology is: Electronic Baiban is basic the structure is by multilayer velar composition, include film of reseau of horizontal resistor film, insulation reseau, electric film, insulation, perpendicular resistor to wait, assorted film and use section volume are identical. Working principle is the tension that increases to secure on resistor film, outside do not have strength effect falls, electric film does not contact resistor film, be measured without voltage, the news that won't have fixed position reacts. When the some that is pressed in resistor film with good thing is nodded, electric current is read to take by test circuit through electric film, resemble checking the voltage that changes to from midpoint of a potentiometer, this voltage and the position that touch a point are concerned, the basis reads taken voltage from level and perpendicular direction, can the X that conversion nods for feeling, y direction position. Screen of resistor mood feeling is means of implementation of scanning of a kind of reseau, the characteristic is when the object pins velar surface, can react the seat that gives an object to pin.
Actor inferior position of the technology analyses:
Advantage: 1, location is relatively exact. 2, need not special drawing, can become feeling operation
Inferior position:
1, write more demanding, insufficient handwriting shows strength not to come out
2, fear cut, once have cut, cannot use
3, response rate is slower
4, cannot do exceed large area
Basically use manufacturer:
China: The United States overcomes dais of number of Er Makerboard desktop
The United States: Polyvison, Interactive Tech
At present the product market of this technology is had rate show glide quickly trend, less manufacturer uses home this technology
2: Electromagnetism induction
The working principle of electromagnetism induction type is: Electromagnetic wave is to be able to pass air and insulation object to have transmission, electromagnetism induction type is the pen that uses to be able to emit electromagnetic wave, the level is perpendicular the reception that two direction arrange coil film composition, velar size and active area are same. Fixed position principle is, the pen of emissive electromagnetic wave emits electromagnetic wave by intermittent means, when the pen stands by the film that receives coil, the electromagnetic wave that induction of the meeting on coil emits to the pen. The electromotive force that the closest from the pen coil group induction goes to is taller, according to the electromotive force that horizontal way and perpendicular direction induction go to, position of coordinate of the X that can win a seat through computation, Y.
