OS-FLASH-A1-L Imported from Eaton”s original factoryEATON”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
OS-FLASH-A1-L Imported from Eaton”s original factorySuitable 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
A. ITO, indium oxide, is a weak conductor. Its characteristic is that when the thickness drops below 1800 angstroms (angstroms = 10-10 meters),
it will suddenly become transparent, with a light transmittance of 80%. If it is thinner, the light transmittance will be reversed.
decreases, and then rises to 80% when the thickness reaches 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 the ITO coating.
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.
2. Capacitive touch screen
The structure of the capacitive touch screen is mainly to coat a transparent thin film layer on the glass screen, and then add a piece of protective
glass outside the conductor layer. The double-glass design can completely protect the conductor layer and sensor.
The capacitive touch screen is plated with long and narrow electrodes on all four sides of the touch screen, forming a low-voltage AC electric field
in the conductive body. When the user touches the screen, due to the electric field of the human body, a coupling capacitance
will be formed between the finger and the conductor layer. The current emitted by the four side electrodes will flow to the contact, and the intensity of the
current is proportional to the distance from the finger to the electrode. The controller located behind the touch screen will It will calculate the proportion
and strength of the current and accurately calculate the location of the touch point. The double glass of the capacitive touch screen not only protects the
conductors and sensors, but also effectively prevents external environmental factors from affecting the touch screen. Even if the screen is stained with
dirt, dust or oil, the capacitive touch screen can still accurately calculate the touch position.
The capacitive touch screen is a transparent special metal conductive substance affixed to the glass surface. When a finger touches the metal layer, the
capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch
position can be determined to obtain information. Because the capacitance changes with temperature, humidity or grounding conditions, its stability is
poor and drift often occurs. This kind of touch screen is suitable for the debugging stage of system development.
3. Infrared touch screen
The touch screen is composed of infrared transmitting and receiving sensing elements installed on the outer frame of the touch screen
. An infrared detection network is formed on the screen surface. Any touching object can change the infrared rays on the contact points to
achieve touch screen operation. Infrared touch screens are not interfered by current, voltage and static electricity, and are suitable for certain
harsh environmental conditions. Its main advantages are low price, easy installation, no need for cards or any other controllers, and can
be used on computers of all levels. In addition, since there is no capacitor charging and discharging process, the response speed is faster than the capacitive type, but the resolution is lower.
