TOUCH SCREEN TECHNOLOGY
Advantages of Resistive Technology
Can be activated with any device
Low cost solution
Low power consumption
Disadvantages of Resistive Technology
Poorer durability compared to other technologies
Very short life, especially considering cosmetic wear
CAPACITIVE TOUCH SCREEN TECHNOLOGY
In the capacitive system, a layer that stores electrical charge is placed on the glass panel.
When a user touches, some of the charge is transferred to the user, so the charge on the capacitive layer decreases.
This decrease is measured in electrodes located at each corner of the monitor.
The computer then calculates the coordinates, from the relative differences in charge at each corner.
