The X-axis nanowire and the Y-axis nanowire are in accordance with certain rules,Encapsulated in PET film by digital packaging automation equipment,Thus forming an induction matrix,Each matrix unit is a proximity sensorAbility to sense touch actions in different orientations,These matrix elements constitute a holographic touch sensing matrix,Inputting the sensing signal to the control chip by the touch sensing matrix,And then eliminate the noise by the control chip Deliver effective touch signals to the upper driver software,Thereby achieving precise positioning, triggering action, and realizing touch function.

The sensing principle of nano touch film belongs to the principle of improved projected capacitance,Replace the ITO layer with a nanowire layer,Accurately calculate signal changes with high-precision measurement algorithms.

Nano touch film with or without ITO layer,Is one of the main features that distinguishes it from other projected capacitive touch screens.
