MULTI-TOUCH PROJECTED CAPACITIVE SCREENS

 

 

DawarTouch introduces its new Multi-Touch Projected Capacitive Touch technology.  Our PCT sensors are designed, manufactured, and supported in the USA at Dawar’s Pittsburgh, PA factory.  Constructed as an all glass solution, our touch screens provide extreme durability and superior optics.  We offer a standard product line from 4.3” - 24”W as well as custom solutions to meet your application requirements.  Dawar’s PCT is the perfect choice for your Medical, Instrumentation or Industrial application. 

Dawar’s Projected Capacitive Touch Screens consist of two ITO/Glass circuits and an Optically Clear Adhesive (OCA) that is used to optically bond the two circuits together.  A decorative lens can be added to the front surface of the sensor to allow for product designs similar to tablet PCs.  This lens is also optically bonded to the sensor layers to achieve high light transmission and low reflectance.  A touch event occurs when a finger or conductive stylus interferes with the electric field projected above the surface. This change in capacitance is detected by the controller which interprets the X and Y coordinates of the event.  Multiple fingers can be tracked simultaneously and the controller supports common multi-touch gestures.
