Projected Capacitive Touch (PCT) technology is a capacitive technology which permits more accurate and flexible operation, by etching the conductive layer. An X-Y grid is formed either by etching a single layer to form a grid pattern of electrodes, or by etching two separate, perpendicular layers of conductive material with parallel lines or tracks to form the grid (comparable to the pixel grid found in many LCD displays).
The greater resolution of PCT allows operation without direct contact, such that the conducting layers can be coated with further protective insulating layers, and operate even under screen protectors, or behind weather and vandal-proof glass. Due to the top layer of a PCT being glass, PCT is a more robust solution versus resistive touch technology...
Ve zkratce: PCT je kapacitni technologie ktera umoznuje presnejsi a flexibilnejsi "provoz":
- ma mnohem vyssi presnost a citlivost, muze byt pouzito vice vrstev
- muze byt pouzita taky pod (ve) sklem, dokaze snimat dotek pres ruzne ochranne folie atd
- tato nebo podobna technologie je pouzita v iPhone
Zkuste ovladat iphone treba pres tricko, nebo pres obal od tycinky :D
