I just learned that in analog resistive touchscreen, conducting layers (usually made of indium tin oxide) is placed perpendicular to each other. One on the top flexible film, and one on the bottom, rigid film. On when the end user presses the top film, the conductors touches and a circuit is thus formed.
I previously asked a related question, and Wouter van Ooijen, who answered the comment question, told me that using parallel linings, the conductor will not necessary touch at the point where the user presses the film. But I am not clear how that would happen. So I made a separate question.
Also, what does the conductor looks like? Are they fine conducting strings placed close together?
