The pressure applied to the touch screen can be determined. In fact, the contact
resistance between the X and Y plates is measured, which is a good indication of the
size of the pressed spot and the applied pressure. A soft stylus, e.g., a finger, leads to
a rather large contact area between the two plates when a large pressure is applied.
A hard stylus, e.g., a pen, leads to less variation in measured contact resistance
since the contact area is rather small.
One plate is biased at one or both terminals during this pressure measurement,
whereas the other plate is grounded, again on one or both terminals. The current
flowing through the touch screen is a direct indication for the resistance between both
plates. A compensation for the series resistance, formed by the touch screen plates
and the internal 1 k resistance of the UCB1400 will improve the accuracy of this
measurement.
