The three corners of the sound wave screen are respectively pasted with transducers
for transmitting and receiving sound waves in the X and Y directions (transducer: made
of special ceramic materials, divided into transmitting transducers and receiving transducers.
It controls The electrical signal sent by the device through the touch screen cable is converted into
sound wave energy and the surface acoustic wave energy formed by the reflection stripes is converted
into an electrical signal.), the four sides are engraved with reflection stripes that reflect surface ultrasonic waves
. When a finger or soft object touches the screen, part of the sound wave energy is absorbed, thus changing the received signal.
After processing by the controller, the
X and Y coordinates of the touch are obtained.
Four-wire resistive screen
The four-wire resistive screen is covered with two layers of transparent conductive layer ITO (ITO: indium oxide, weak conductor)
between the surface protective coating and the base layer. The characteristic is that when the thickness drops below
1800 angstroms (angstrom = 10-10 meters) It will suddenly become transparent, and the light transmittance will decrease
when it gets thinner. When the
thickness reaches 300 angstroms, the light transmittance will increase again. It is the main material of all resistive screens
and capacitive screens.), the two layers correspond to the X and Y axes respectively. They are They are insulated with
fine transparent insulating particles. When touched, the pressure generated connects the two conductive layers. Due to the
change in resistance value, the X and Y coordinates of the touch are obtained. [!–empirenews.page–]
Five-wire resistive screen
The base layer of the five-wire resistive screen is covered with a transparent conductive layer ITO
that adds voltage fields in the X and Y directions to the same layer. The outermost nickel-gold conductive layer (nickel-gold
conductive layer: the outer conductive layer of the five-wire resistive touch screen The outer conductive layer 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.) It is only used as a pure conductor.
When touching, use a The position of the touch point is measured by detecting the X-axis and Y-axis voltage values of the
contact point. The inner layer ITO requires four leads and the outer layer one, for a total of 5 leads.
capacitive screen
The surface of the capacitive screen is coated with a transparent conductive layer of ITO,
and the voltage is connected to the four corners. Tiny DC current dissipates on the screen surface, forming a uniform
electric field. When the screen is touched by hand, the human body acts as one pole of the coupling capacitor, and the
current collects from the four corners of the screen to form another coupling capacitor. On one pole, the controller
calculates the relative distance from the current to the touch location to obtain the coordinates of the touch.
Infrared screen
The infrared touch screen uses a dense infrared matrix in the X and Y directions to detect and locate the user”s touch.
The infrared touch screen installs a circuit board frame in front of the display. The circuit board arranges infrared transmitting
tubes and infrared receiving tubes on the four sides of the screen, corresponding to each other to form a horizontal and vertica
l infrared matrix. When a user touches the screen, his or her finger will block the horizontal and vertical infrared rays passing through
that location, so the location of the touch point on the screen can be determined. Any touching object can change the infrared rays on the
contact points to achieve touch screen operation.
