There are now many different touchscreen technologies on the market. Depending on the application or area of application, they all have different advantages and disadvantages. In this article, we will briefly introduce you to the advantages of capacitive touchscreen technology, which is characterized by high durability, reliability and optical transparency.
The way the capacitive touchscreen works is quite simple. A square wave voltage is applied at the vertices to generate a uniform electric field. The surface is provided with a transparent metal-oxide-coated film applied to a glass substrate, which is conductive. A layer of glass is applied to the outside as scratch protection.
If the user touches the touchscreen with his finger, a charge transport in the electric field is created. This makes it possible to measure at the corners where the finger has touched the surface.
Benefits at a glance
The many advantages of capacitive touchscreen technology usually make up for its higher price compared to other technologies, because displays with this technology
- are very precise
- have a good resolution and optical transparency
- are dirt-resistant and resistant to chemicals
- and are ideal for outdoor use, as the sensitivity to mechanical damage is lower than with other touchscreen technologies.
