There is a variety of touchscreen technologies with different methods of sensing touch. A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other alon… WebTouch Screen overlays incorporate sophisticated optical imaging technology and a robust design to provide a durable touch solution perfect for high-traffic public applications. The glass overlay preserves the …
