In capacitive systems, the layer that stores the charge is placed on the glass panel of the display. When the user touches the display with a finger or finger, some of the charge is transferred to the user, so the charge on the capacitive layer is reduced. This reduction is measured in circuits located at each corner of the monitor.

The display uses sonic system technology, with two transducers (a receiver and a transmitter) placed along the x- and y-axes of the display glass. It also places a reflector to reflect the electrical signal sent from one sensor to the other.

What is the difference between multi-touch and touch screen?
You can control the touchscreen by tapping its display interface with your finger. Each of these touch commands is a touch event. With multi-touch, the touchscreen will be able to recognize two or more touch points simultaneously as touch events. Most smartphones and tablets have multi-touch capabilities.
