4.1 Intended Use
The primeTOUCH flat is a touch overlay which is mounted to a professional LC Display. This
results in an independent multi touch screen, based on infrared diode technology. primeTOUCH
flat provides an ultra-flat touch surface with anti-glare front glass and a very thin bezel where the
small IR diodes are located. As primeTOUCH flat can communicate via the HID interface it is a
plug&play solution. Always pay attention to the original manuals of the professional LC Displays,
