Touch Screen OverlaysTouch screen overlays are electronic devices that are used to add touch-sensitive capabilities to a display screen or other surface. These overlays typically consist of a transparent or semi-transparent layer that is placed over the surface of the display, and are equipped with sensors and other electronic components that can detect and respond to touch input. Touch screen overlays are commonly used in a wide range of applications, including smartphones, tablets, and other portable devices, as well as kiosks, point-of-sale systems, and other interactive displays. They are often preferred over other types of touch-sensitive technology because they are relatively inexpensive and easy to install.
