Computer Science for IGCSE & O level - Hardware (Section 7 - No. 6)
In a resistive touchscreen, how is the touch position determined?
By sensing the change in electrical resistance when the screen is touched.
By detecting the interruption of infrared beams.
By measuring the capacitance of the touch.
By emitting a focused beam of light.
Paliwanag
Resistive touchscreens use layers that make contact when pressed and change electrical resistance.
