interactive golf screen.1/1000 inch) transparent isolation points separate the two conductive layers. When a finger touches the screen, the two conductive layers come into contact at the touch point, the resistance changes, a signal is generated in both X and Y directions, and then it is sent to the touch screen controller. The controller detects this contact and calculates the position of (X, Y), and then operates according to the way of simulating a mouse. This is the most basic principle of resistive technology touch screen. The key of the resistive touch screen is material technology. Commonly used transparent conductive coating materials are: A, ITO, indium oxide, weak conductor. The characteristic is when the thickness drops below 1800 Angstroms (Angstroms = 10-10 meters). It suddenly becomes transparent with a light transmittance of 80%. When it is thinner, the light transmittance decreases instead, and rises to 80% when the thickness is 300 angstroms. ITO is the main material used in all resistive technology touch screens and capacitive technology touch screens. In fact, the working surface of resistive and capacitive technology touch screens is ITO coating. ?? B. Nickel-gold coating, the outer conductive layer of the five-wire resistive touch screen uses a ductile nickel-gold coating material. Because the outer conductive layer is frequently touched, the use of a ductile nickel-gold material is intended to extend Service life, but the process cost is relatively high. Although the nickel-gold conductive layer has good ductility, it can only be used as a transparent conductor. It is not suitable as a working surface of a resistive touch screen because of its high conductivity and the metal is not easy to achieve a very uniform thickness. It should not be used as a voltage distribution layer. It can only be used as a probe. Floor. 1.1 four-wire resistive screen on each level of the metal layer increases the work of two transparent four-wire analog resistive technology 5V constant voltage: a vertical direction, a horizontal direction. A total of four cables are required. Features: high resolution, high-speed transmission response. Surface hardness treatment to reduce abrasion, scratches and anti-chemical treatment. With glossy and matte finish. One-time calibration, high stability and never drift. Five-wire resistive screen 1.2 Base five-wire resistive touch screen technology the voltage field in two directions by precision resistor networks are added to the conductive working surface of the glass, we can simply be understood as two directions staggered working voltage field It is added on the same working surface, and the outer layer of nickel-gold conductive layer is only used as a pure conductor.
