How Resistive Touch Works
4-Wire Resistive TechnologyA resistive touch panel is a mechanical sensor. It consists of 2 conductive ITO layers separated by air gap and tiny transparent insulation spacer dots. When a finger or stylus presses on the top layer of ITO PET film (usually X axis), which means that it physically touches the lower layer of ITO glass substrate (usually Y axis), the voltage at the contact point is measured through the 4-wire printed on the edges of both ITO layers, and then the location can be computed by the controller. After the finger or stylus releases, the top layer resumes to its original position.
ASIAPRO offers a wide range of resistive touch constructions:
- Film–Glass (F-G)
- Film-film (F-F)
- Film-film-PC/PMMA (F-F-PC/PMMA)
- Touch window / Touch panel with decorative film (LENS-F-F-PC/PMMA/Glass; LENS-F-G)
