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. |
