Capacitive Touch Screen
consists of a glass panel with a capacitive (charge
storing) material coating its surface. Unlike resistive touch screens,
where any object can create a touch, they require contact with a bare
finger or conductive stylus. When the screen is touched by an
appropriate conductive object, current from each corner of the
touch screen is drawn to the point of contact. This causes oscillator
circuits located at corners of the screen to vary in frequency
depending on where the screen was touched. The resultant frequency
changes are measured to determine the x- and y- co-ordinates of the
touch event. Capacitive type
touch screens are very durable, and have a high clarity. They are used
in a wide range of applications, from restaurant and POS use to
industrial controls and information kiosks.

Resistiveb Touch Screen
responds to the pressure of a
finger, a fingernail, or a stylus. They typically comprise a glass or
acrylic base that is coated with electrically conductive and resistive
layers. The thin layers are separated by invisible separator dots.
When operating, an electrical current is constantly flowing through
the conductive material. In the absence of a touch, the separator dots
prevent the conductive layer from making contact with the resistive
layer. When pressure is applied to the screen the layers are pressed
together, causing a change in the electrical current. This is detected
by the touchscreen controller, which interprets it as a
vertical/horizontal coordinate on the screen (x- and y-axes) and
registers the appropriate touch event.
Resistive type touchscreens are generally the most affordable.
Although clarity is less than with other touchscreen types, they're
durable and able to withstand a variety of harsh environments. This
makes them particularly suited for use in POS environments,
restaurants, control/automation systems and medical applications.
