What Type of Touchscreen Technology Do Mobile Devices Use?

Mobile devices have become increasingly popular. Statistics show that four-fifths of the global population owns a smartphone. In addition to a smartphone, many people own a tablet. Whether it's a smartphone or tablet, though, all mobile devices feature a touchscreen. They have a display, such as a liquid-crystal display (LCD), with an integrated display.

Of course, touchscreens are available in different technologies. All touchscreens can detect and respond to touch commands. The technology that powers a touchscreen will simply determine how it performs these operations. So, what type of touchscreen technology do mobile devices use?

Most Mobile Devices Use Capacitive Technology

While there are exceptions, most mobile devices use capacitive technology. Capacitive is the single most popular type of touchscreen technology for mobile devices. More smartphones and tablets use capacitive technology than any other type of touchscreen technology.

Capacitive is a type of touchscreen technology that leverages an electrostatic field, as well as the human body's conductive properties, to detect touch commands. When turned on, capacitive touchscreens will generate a uniform electrostatic field. They'll constantly measure this electrostatic field while looking for changes. If you perform a touch command with a bare finger, your body will absorb some of the electrostatic field. The capacitive touchscreen will detect this change in capacitance and, thus, respond with the appropriate action.

Along with resistive, capacitive is one of the two primary classifications of touchscreen technologies. Resistive technologies don't rely on an electrostatic field. Rather, they detect touch commands based on pressure. Resistive touchscreens feature two layers that are separated by air. When you touch the top layer, it will push into the bottom layer.
