Touch Screen
  There are a variety of touchscreen technologies that have different methods of sensing touch. AMP Display Inc. mainly offers two of those technologies, capacitive and resistive.(See all capacitive Touch Panel Products)

 

Capacitive Touch Screen

Capacitive touch screen technology is a popular and durable technology that is used in a wide range of applications. It has a higher clarity than resistive technology, but it only responds to finger contact and will not work with a gloved hand or pen stylus. A capacitive touch screen consists of a glass panel with a capacitive (charge storing) material coating its surface. Circuits located at corners of the screen measure the capacitance of a person touching the overlay.




Resistive Touch Screen

Resistive touch screen technology consists of a glass or acrylic panel that is coated with electrically conductive and resistive layers. The thin layers are separated by invisible separator dots. When operating, an electrical current moves through the screen. When pressure is applied to the screen the layers are pressed together, causing a change in the electrical current and a touch is registered.
