XV-440-10TVB-1-50 Full range touch screen EATONEATON”s commonly used touch screens can be divided into four categories: resistive touch screens, surface capacitive touch screens, infrared touch screens, and surface acoustic wave touch screens
XV-440-10TVB-1-50 Full range touch screen EATONSuitable for steel manufacturing, thermal power generation, hydroelectric power generation, nuclear power generation, wind power generation, gas supply, and other glass manufacturing, paper mills, mechanical manufacturing, electronic manufacturing, automotive manufacturing, aviation manufacturing, chemical manufacturing, coal mining and selection, oil and natural gas mining and selection, metal mining and selection, and non-metallic mining and selection
B. Nickel-gold coating. The outer conductive layer of the five-wire resistive touch screen uses a nickel-gold coating material with good ductility. Due to frequent touching
, the purpose of using a nickel-gold material with good ductility is to extend the service life of the outer conductive layer. , 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 and is not suitable as a working surface for a resistive touch screen. Because it has
high conductivity and the metal is not easy to achieve a very uniform thickness, it is not suitable for use as a voltage distribution layer and can only be used as a detector. layer.
1.1 Four-wire resistive screen
The two transparent metal layers of the four-wire resistance analog technology work with a constant voltage of 5V added to each layer: one vertically and one horizontally.
A total of four cables are required. Features: High resolution, high-speed transmission response. Surface hardness treatment to reduce abrasions, scratches and chemical
protection. Available in glossy and matte finishes. Once calibrated, it has high stability and will never drift.
1.2 Five-wire resistive screen
The base layer of the five-wire resistance technology touch screen adds voltage fields in both directions to the conductive working surface of the glass through a precision
resistor network. We can simply understand that the voltage fields in both directions are applied to the same working surface in a time-sharing manner. The outer nickel-gold
conductive layer is only used as a pure conductor. There is a method of detecting the X-axis and Y-axis voltage values of the inner ITO contact point time-sharing after touching to
measure the position of the touch point. The five-wire resistive touch screen requires four leads in the inner layer of ITO, and only one conductor in the outer layer. The touch screen
has a total of 5 leads. Features: High resolution, high-speed transmission response. High surface hardness reduces abrasions, scratches and resists chemical treatments.
It can still be used after 30 million contacts with
the same point. Conductive glass is the base material. Once calibrated, it has high stability and will never drift. The five-wire resistive touch screen has the disadvantages of high
price and high environmental requirements.
1. 3 Limitations of resistive screens
Whether it is a four-wire resistive touch screen or a five-wire resistive touch screen, they are a working environment that is completely isolated from the outside world.
They are not afraid of dust and water vapor. They can be touched by any object and can be used to write and draw. They are more suitable for the field of industrial control.
and limited-person use within the office. A common disadvantage of resistive touch screens is that because the outer layer of the composite film is made of plastic material, uninformed
people may scratch the entire touch screen if they touch it too hard or use a sharp object, causing it to be scrapped. However, within limits, scratches will only damage the
outer conductive layer. Scratches on the outer conductive layer do not matter for five-wire resistive touch screens, but are fatal for four-wire resistive touch screens.
