(1) The surface acoustic touch screen is a high-durability structure, which is scratch-resistant and anti-violence. Because the working surface of the surface acoustic touch screen is a layer of invisible and indestructible acoustic energy, the base glass of the touch screen does not have any interlayer and structural stress (the surface acoustic touch screen can be developed to be directly made on the surface of the CRT without any "screen"). Therefore, it is very resistant to violence and suitable for use in public places.
(2) Clear and beautiful. Because of the small structure, there is only one layer of general glass, and the light transmittance and clarity are much better than those of capacitive and resistive touch screens.
(3) Fast response. It's the fastest of all touchscreens, and it feels smooth to use.
(4) Stable function. Because the principle of surface acoustic wave skill is stable, and the manipulator of the surface acoustic wave touch screen calculates the contact position by measuring the position of the attenuation moment on the time axis, the surface acoustic wave touch screen is very stable and the accuracy is also very high, and now the accuracy of the surface acoustic wave skill touch screen is usually 4096x4096x256 level force.
(5) The defect of the surface acoustic touch screen is that the dust and water droplets on the surface of the touch screen also block the transmission of the external sound wave, although the clever control card can distinguish it, but when the dust accumulates to a certain extent, the signal will be attenuated very fiercely, and the surface acoustic wave touch screen becomes sluggish or even does not work at this moment. Therefore, on the one hand, the surface acoustic wave touch screen introduces a dust-proof touch screen, and on the other hand, it is recommended to clean the touch screen regularly every year.
(6) The touch screen can be activated with fingers, gloved fingers, or soft substances that can absorb sound wave energy. If a beverage bottle is placed on a flat sonic touchscreen, the system does not treat the bottle as a contact, but continuously recognizes the finger-activated contact signal. This is not possible for resistive and capacitive touch screens.
(7) The surface acoustic touch screen can know exactly what is dust and water droplets, what are fingers, and how much is in contact. Because our finger contact is under the accuracy of 4096x4096x256 level of force, the contact data of 65 times per second cannot be unchanged, and the dust or water droplets are not the same at all, and the controller will automatically identify the interference when it finds that the thread does not change for more than 3 seconds after a "contact".
(8) The surface acoustic touch screen also has a third axis (Z-axis), which is the pressure axis response. This is because the greater the force the user touches the screen, the wider and deeper the attenuation gap in the waveform of the received signal. Of all the touchscreens, only the sonic touchscreen has the function of sensing contact pressure. With this function, each point of contact is not just two simple states with contact and no contact, but becomes a perceptual switch that mimics the value. This function is very useful, for example, in the multimedia information query software, a button can control the broadcast speed of the animation or image, the color brightness, the volume, etc.

Veriton touch screen - an overview and working principle of capacitive touch screen
An overview of the principles
To complete multi-touch on the capacitive screen, it relies on adding electrodes of mutual capacitance, in short, the screen is divided into blocks, and a group of mutual capacitance modules are set up in each area to work independently, so the capacitive screen can independently detect the touch status of each area.

What are the advantages of surface acoustic touch screen?
1. The optical performance is the best. The clarity and light transmittance are the highest, the reflection is the least, and there is no color distortion, this is because the sound wave screen body is pure glass, unlike the resistive screen with multiple layers of composite film; The capacitive screen is coated with a layer of film on the surface, and the light transmittance is worse.
2. Anti-scratch and anti-barbaric use ...
