What is Resistive Touch Screen Panels?
A resistive touchscreen panel comprises several layers, the most
important of which are two thin, transparent electrically-resistive
layers separated by a thin space. These layers face each other with
a thin gap between. The top screen (the screen that comes
incontact) has a coating on the underside surface of the screen.
Just beneath it is a similar resistive layer on top of its
substrate. One layer has conductive connections along its sides,
the other along top and bottom.
A voltage is applied to one layer, and sensed by the other. When an
object, such as a fingertip or stylus tip, presses down onto the
outer surface, the two layers touch to become connected at that
point: The panel then behaves as a pair of voltage dividers, one
axis at a time. By rapidly switching between each layer, the
position of a pressure on the screen can be read.
We see use of Resistive touch in restaurants, factories and
hospitals due to its high resistance to liquids and contaminants. A
major benefit of resistive touch technology is its low cost.
Additionally, as only sufficient pressure is necessary for the
touch to be sensed, they may be used with gloves on, or by using
anything rigid as a finger/stylus substitute.
Disadvantages include the need to press down, and a risk of damage
by sharp objects. Resistive touch screens also suffer from poorer
contrast. Due to having additional reflections from the extra
layers of material (that the air gap separates) that you place over
