DETAILED DESCRIPTION
OPERATION - TOUCH SCREEN
TSC2301
SLAS371D – SEPTEMBER 2002 – REVISED AUGUST 2004
OVERVIEW (continued)
Figure 44. Typical Circuit Configuration
A resistive touch screen works by applying a voltage across a resistor network and measuring the change in
resistance at a given point on the matrix where a screen is touched by an input stylus, pen, or finger. The change
in the resistance ratio marks the location on the touch screen.
