Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In ____, the touch screen is coated with a materialin order to Store the electrical charges generated by a touch. Thecharge is measured by panels located at each corner of the device and processed.
A
resistive technology
B
capacitive technology
C
surface wave technology
D
None of the above
Explanation: 

Detailed explanation-1: -Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event.

Detailed explanation-2: -Resistive Touchscreen The inside surface is coated with a transparent material (ITO) that makes electrical contact when pressure is applied. These voltages are then converted to X and Y coordinates, which are sent to the controller.

Detailed explanation-3: -Resistive touchscreens are composed of two electrically conductive layers of thin metal film separated by a tiny air gap.
