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.
