Ireland-based Rapt Touch (RAPT) is a provider of optical multi-touch systems for display makers and systems integrators. RAPT developed a unique and patented optical touch technology that is fully compatible with OLED displays, at all sizes.
RAPT's FTIR technology is based on low-cost LEDs that create an optical mesh of infrared light signals, read by photodetectors. The LEDs and the photodetectors are placed on the edge of the OLED display. The performance is not affected by capacitive coupling or display pattern noise, and can be used on any screen size.
