Technology-resistive touch

ÉCRANS TACTILES

Resistive touch screens are made up of two layers, with a thin metal film conductor and separated by a tiny layer of air. When pressure is applied on the surface of the touchscreen, the two sheets are in contact, closing the circuit.

 

The optical touch technology

ÉCRANS TACTILES

Touch screens, optical use cameras that scan continuously the touch screen. When an object comes into contact with the touch screen, a part of the light is blocked, and the information of the two sensors and triangulation mathematics are then used to calculate the location of the point of contact.

– Monitors optical touch have high light transmission and, as they use optical sensors, they can be operated with both conductive materials and non-conductive.

THE CAPACITIVE TOUCH TECHNOLOGY

ÉCRANS TACTILES

The capacitive touch screen is covered with a film transparent conductor, who can use the conductivity of the human body as a carrier for entry when it is touched with the fingertips. Most smartphones and terminals location indoor use capacitive touch screens electrostatic.
