What type of screen uses layers of glass to create electric fields?

A capacitive touch screen operates by utilizing layers of glass that generate electric fields. When a user touches the screen, their finger, which conducts electricity, alters the electric field at the point of contact. The screen detects this change and registers the touch input. This technology is commonly found in modern smartphones and tablets due to its ability to support multi-touch gestures and provide a responsive user experience, making it highly popular.

In contrast, a resistive touch screen relies on pressure applied to the surface of the screen to register input, typically requiring a stylus or finger to press down on the top layer of the display. An infrared heat touch screen uses a grid of infrared light beams to detect touches, while an OLED display refers to a specific type of display technology that provides vibrant colors and is not inherently related to how touch input is detected. Thus, the unique mechanism of electric fields in capacitive screens distinguishes them from these other types.
