The technology of Project Capacitive TP is to measure the capacitance change among different polarities of the patterns between X-axis (X-layer) & Y-axis (Y-layer) then to detect the actual touch positions. Due to the human body is moisturized and considerably suitable as a better conductor, so, when human fingers touch these polarities, the capacitance between the fingers & the polarities will be changed therefore, the actual points being touched can be detected; unlike the pressure sensing method of Resistive Touch, CCD visual sensing of Optical Touch & Sonic Acoustic sensing of SAW.
