4.1 Surface acoustic waves
Surface acoustic wave, a type of ultrasonic wave, is a mechanical energy wave that propagates shallowly on the surface of a medium (such as
a rigid material such as glass or metal). Through the wedge-shaped triangular base (strictly designed according to the wavelength of the surface wave),
directional and small-angle surface acoustic wave energy emission can be achieved. Surface acoustic wave has stable performance, is easy to analyze,
and has very sharp frequency characteristics in the process of transverse wave transmission. In recent years, its application has developed rapidly in the
direction of non-destructive testing, imaging and de-wave devices. Theoretical research on surface acoustic waves, semiconductor materials, acoustic wave
Guidance materials, detection technology and other
technologies are already quite mature. The touch screen part of the surface acoustic wave touch screen can be a flat, spherical or cylindrical glass plate installed
in front of a CRT, LED, LCD or plasma display screen. Vertical and horizontal ultrasonic transmitting transducers are fixed on the upper left and lower right corners of
the glass screen, and two corresponding ultrasonic receiving transducers are fixed on the upper right corner. The four peripheries of the glass screen are engraved with
very precisely spaced reflection stripes at 45° angles from sparse to dense.
4.2 Working principle of surface acoustic wave touch screen
Take the X-axis transmitting transducer in the lower right corner as an example: The transmitting transducer converts the electrical signal sent from the controller through the touch screen
cable into sound wave energy and transmits it to the surface on the left, which is then reflected by a set of precision reflection stripes under the glass plate. The sound wave energy
is reflected into an upward uniform surface and transmitted. The sound wave energy passes through the surface of the screen, and then is gathered into a line to the right by the
upper reflection stripes and transmitted to the X-axis receiving transducer. The receiving transducer will return the surface acoustic wave. The energy becomes an electrical
signal. When the transmitting transducer emits a
narrow pulse, the sound wave energy reaches the receiving transducer through different paths. The one on the far right arrives earliest, and the one on the far left arrives last.
The early and late arrivals are superimposed into one For a wider waveform signal, it is not difficult to see that the received signal collects all the sound wave energy that has
returned after different long and short paths in the X-axis direction. The distance they have traveled on the Y-axis is the same, but on the The nearest one has traveled twice the
maximum distance on the X-axis. Therefore, the time axis of this waveform signal reflects the position of each original waveform before superposition, which is the X-axis
coordinate. When there is no touch, the waveform of the received signal is exactly the same as the reference waveform. When a finger or other object that can absorb or block
sound wave energy touches the screen, the sound wave energy traveling upward along the X-axis through the finger is partially absorbed, which is reflected in the received waveform
that is, there is an attenuation gap in the waveform at a certain moment. The received
waveform corresponds to the signal attenuation of a gap in the part blocked by the finger. Calculating the position of the gap means that the touch coordinate controller analyzes
the attenuation of the received signal and determines the X coordinate based on the position of the gap. Then the same process for the Y axis determines the Y coordinate
of the touch point. In addition to the X and Y coordinates that general touch screens can respond to, surface acoustic wave touch screens also respond to the third axis Z-axis
coordinates, which means they can sense the value of the user”s touch pressure. The principle is calculated from the attenuation of the received signal attenuation
Once the three axes are determined, the controller transmits them to the host.
4.3 Characteristics of surface acoustic wave touch screen
The clarity is higher and the light transmittance is good. Highly durable and good in scratch resistance (compared to surface film on resistors, capacitors, etc.). Very responsive.
Not affected by environmental factors such as temperature and humidity, high resolution and long life (50 million times with good maintenance); high light transmittance (92%),
able to maintain clear and translucent image quality; no drift, only required during installation One-time correction; there is a third axis (i.e. pressure axis) response, which is
currently used more in public places. Surface acoustic wave screens require regular maintenance,
because dust, oil and even beverage liquids contaminating the surface of the screen will block the wave guide groove on the surface of the touch screen, preventing the waves
from being emitted normally, or causing the waveform to change and the controller to be unable to recognize it normally, thus affecting the performance of the screen. For normal
use of the touch screen, users must pay strict attention to environmental hygiene. The surface of the screen must be wiped frequently to keep it smooth, and a complete wipe must be performed regularly.
