Capacitive Touch Screen Technology
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.
Used on smart monitor , projected capacitive is the most widespread touch screen, How is the structure like?
There are various structures in projected capacitive technology. "One sheet piled-up structure" has X and Y electrodes piled on one sheet. "One sheet two-sided structure" has X and Y electrodes on its surface and backside of one sheet respectively. "Two-sheets-laminated structure" consists of two sheets facing each other with electrodes in between.
