A Capacitive Touchscreen is an all-glass sensor made by coating TAO(Tin Antimony Oxide) on surfaces of the glass substrate, for which capacitance of human body can be used. It greatly enables smooth operation in almost any tough environment and poor conditions. Capacitive touch screen is not affected by outside elements and have high clarity. So its application fields are very popular in outdoor kiosks, industrial environments, Guide system, POS etc. Its structure and operating principles are as follows.



As shown above, it is composed of 1 sheet of glass substrate without using top layer; it has higher light transmittance and better surface durability. But as it does not react to the gloved hands or non conductive materials, limited input devices like a finger must be adopted. An electrode pattern is printed along the edge on the conductive layer. The glass overcoat is also fused over the conductive coating to protect and seal the sensor.
Advantages of Capacitive Touch
- Slight touch can be detected as it reacts to just a little static electricity
- Good durability with a special metal coating
- Long life (100 million times touch)
- Great endurance in tough environment of weather, contaminants, or liquid
- Excellent light transmittance
