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 microLED 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 display. The performance is not affected by capacitive coupling or display pattern noise, and can be used on any screen size.
RAPT's solution offers superb optical and touch performance and is highly compatible with OLED and microLED displays. The technology is cost effective as it is based on off-the-shelf components and its costs grow linearly with size (unlike other touch solutions).
RAPT Touch is a privately held company, with over 90 issued patents. RAPT’s products have already been deployed in several projects and systems, including Google’s 55” Jamboard, and HiteVision products.
