Surface Acoustic Wave Screen
The three angles acoustic screen paste with X, Y direction of the transmitting and receiving acoustic transducer (transducer: made from special ceramic materials, into launching transducer and receiver transducer. Is to control device through the touch screen cable into electrical signals sent to and from the acoustic surface wave reflective stripes converging energy into electrical signals.),LCD Monitors the four sides carved surface of the ultrasonic reflection reflective stripes. When touching the screen with your fingers or soft objects, some acoustic energy is absorbed, thus changing the received signal, controller of the deal and touch the X, Y coordinates.
4 wire resistive screen Four-wire resistive screen in the surface protection coating and covered with two layers of transparent primary conductivity between the layer ITO (ITO: Indium, weak electrical conductors is characterized by the thickness down to 1800 when Egypt (Egypt = 10-10 m) below will suddenly become transparent, then thin down light transmission rate would decrease to 300 Egyptian thickness transmittance rose again. is that all resistors and capacitors screen main screen material.), two correspond to X, Y axis,Touchscreen LCD it is the door fine particles with a transparent insulation between the insulation, when the touch when the pressure so that the two conductive layer connected, as changes in resistance and touch the X, Y coordinates.
5 wire resistive screens covered with grass-roots on the X, Y two directions of the voltage field plus a layer of transparent conductivity in the same layer of ITO, the outermost layer of gold conductive layer of nickel (nickel deposit conductive layer: 5 wire resistive touch screen of the outer conductive layer scalability is a good use of nickel-gold coating materials, outer conductive layer due to the frequent touch, use good ductility nickel deposit materials in order to extend the service life.) PC monitor is only used as a pure conductor, when touched, with sub- point of contact when the X-axis and the detection of Y-axis voltage method measured touch point. ITO need four inner lead, the outer one, a total of five lead.
