Infrared touch screens rely on multiple pairs of infrared transmitting and receiving tubes to work.
The performance and life of the infrared tubes are relatively reliable. Any object that blocks light can
be used as a touch object. However, infrared touch screens use nearly 100 pairs of sensors and
share peripheral circuits. , this requires that the sensor itself not only has good performance, but also
requires that the “light-resistance characteristics” and “junction capacitance” of nearly 100 pairs of infrared
diodes should be consistent. In practical applications, if any pair fails, it can be discovered during the power-on
self-test and ignored thereafter, and replaced by adjacent infrared rays. Since each pair of infrared rays only ”
supervises” a narrow band of about 6mm, and Fingers are usually around 15mm thick and are not noticeable to
the user. However, if there is no aging test for infrared emission tubes during the production process and there is
no good quality management system, nearly 100 pairs of sensors will soon no longer be a problem of one or two
pairs being “left behind”, and the overall lifespan will be difficult to guarantee. The figure below (Figure 6-2) is a schematic diagram of the infrared touch screen

The capacitive touch screen itself is actually a set of precision leakage sensors, which cannot be touched by gloved
hands. Due to the use of capacitive methods, drift occurs. The capacitive touch screen will be introduced in detail in
the next section. Ultrasonic touch screens include surface acoustic wave touch screens and body wave acoustic wave
touch screens, both of which use electro-acoustic piezoelectric transducers as sensors. The piezoelectric transistors used
in the receiving sensor and the
transmitting sensor are not the same type, and the doping materials during manufacturing are slightly different. Differently,
the transmitting transducer is more powerful and the receiving transducer is more sensitive. The piezoelectric transducer has a
long life and stable operation. Normal operation can guarantee no problems for 10 years. After the touch screen is installed, the
transducer is hidden, but care needs to be taken during transportation and installation. The exposed transducer crystal cannot be
collided or squeezed. The surface acoustic wave touch screen has two pairs of sensors on the X and Y axes. It uses surface acoustic
waves on the screen surface to detect finger touches. It can be said that the working surface is a layer of invisible and indestructible
sound energy. It is not afraid of violent use and is most suitable for public information. Inquire.
The above has discussed some concepts in the field of touch screen technology. Of course, it is just a discussion of purely technica
principles. To judge a touch screen, the technical principles alone are only part of it. To be applied to various fields, touch screens
must withstand thousands of touches. Touch, the durability of the selected materials, the response speed, and whether the price is
affordable are all rational ways to judge a touch screen.
Since the current touch screens based on resistive technology are low-priced and can satisfy most of them, the following focuses on
the basic principles of resistive touch screens: The screen part of the resistive touch screen is a multi-layer composite film that is very
compatible with the surface of the display. It consists
of a Laminated glass or plexiglass is used as the base layer, and the surface is coated with a transparent conductive layer, which is
then covered with a layer of outer surface hardened, smooth and scratch-resistant plastic layer. Its inner surface is also coated with a transparent conductive layer, and the two conductive layers are There are
many tiny (less than a thousandth of an inch) transparent isolation points between the layers to insulate them. As shown in Figure 6-3
