And then to send the touch screen controller controller detects this contact and to calculate the (X, Y) position, according to the manner of analog mouse, this is the basic principle of the key resistance class touch screen resistive touch screen technology is the materials science and technology, transparent conductive coating material: AITO, indium oxide, weak conductors feature is when the thickness is reduced to 1800 angstroms (? = 10-10 m) below will suddenly become transparent, the light transmission rate of 80%. and then thin down the light transmission rate would decrease to 300 angstroms thickness Shiyou rose to 80% of ITO is the main material used in all resistance touch screen technology and capacitive touch screen technology. There is no need for any connection between cell phone jammer intelligent systems.
In fact the face of resistance and capacitance touch screen technology is the ITO coating. B nickel gold coating, five-wire resistive touch screen of the outer layer of conductive scalability is a good nickel gold coating materials, conductive outer layer due to the frequent touch nickel deposit materials with good ductility in order to extend the service life to work with one, but the technology costs more expensive nickel deposit conductive layer scalability, but only for transparent conductors, not suitable for resistive touch screen on the face, because of its high conductivity , and the metal is not easy to achieve very uniform thickness suitable for voltage distribution layer, only as a probe layer. Insert the power supply of the first detector of cell phone jammer intelligent system into the city electricity socket.
Four-wire resistive analog technology, two layers of transparent metal layer, each layer increase the 5V constant voltage: a vertical direction, a horizontal direction required a total of four cable characteristics: high-resolution, high-speed response surface hardness, reduce rub injury scratch and anti-chemical treatment with glossy and matte processing correction, high stability, and never drift. grass-roots of the five-wire resistive touch screen technology to field voltage in both directions through the precision resistor network plus conductive glass surface, we can understand the time-sharing work for both directions of the voltage field applied to the same work surface. Adjust all detectors of cell phone jammer intelligent system according to the instruction and restart all detectors of cellphone jammer intelligent system.
Conductive layer of the outer layer of nickel and gold only just used as a pure conductor, has a touch time-sharing detection inner ITO contact with the X-axis and Y-axis voltage value measured touch points the location of five-wire resistive touch screen inner ITO needs four leads, only the outer layer for the conductor is just a touch screen have to Lead a total of five characteristics: high-resolution, high-speed response, high surface hardness and reduce abrasion scratch and anti-chemical treatment with point contact 30 million times the usable conductive glass substrate media time correction, high stability, and never drift five-wire resistive touch screen with high price and environmental requirements of the shortcomings. The importance of installing cell phone jammers in the prison will be stated in the next paragraph.
Whether it is a four-wire resistive touch screen, or five-wire resistive touch screen, they are a complete isolation of the working environment, not afraid of dust and water vapor, which can be used to touch any object that can be used to draw and write, more suitable for industrial control field and limited office use resistive touch screen, a common drawback is that because the outer layer of the composite film of plastic material, do not know too much force or may scratch the touch screen with sharp touch scrapped, however, within limits, is zoned injury will only hurt the conductive outer layer, the conductive outer layer of scratch for a five-wire resistive touch screen, four-wire resistive touch screen is fatal. It is concerning about the model selection and technical index of phone jammer .
