Structure & Operating Principle:
Capacitive touch screen is a piece of 2 layer of compound glass
with double side transparent conductive coating that conducts a
continuous electrical current across the sensor.
There is electrode pattern printed along the edges distributes a
low voltage filed over the conductive layer.
The human body is also an electrical device which has stored
electrons and therefore also exhibits capacitance.
When a finger touches the screen and draws a minute amount of
current to the point of contact ,creating a voltage drop.
The current flow from each corner is proportional to the distance
to the touch point. During a touch ,capacitance forms between the
finger and the sensor grid. The touch location is calculated from
the changing electrical characteristics of the sensor grid.
Touch Screen is the replacement of mouse and wires between people
and machines, it makes our life more and more convenient .
With the development of the science technology, touch screen will
be widely used around our lifes.
