Product Information
Enjoy the most natural interactive digital experience
Modern meeting spaces drive the demand for advanced touch technology with innovative design. To support interactive sessions, the NEC InGlassTM Touch Board along with the responsive passive pen brings superior paper-like writing with minimal latency to a digital canvas. With its slim bezel design, the technology seamlessly integrates into modern interior styling.
High brightness levels ensure excellent readability and image reproduction even in today’s typically bright meeting spaces where maintaining a motivational environment is paramount. The anti-glare coating minimizes disturbing reflections and helps to eliminate niggling fingerprints on the touch surface.
