Stadium IGT: Printed light-guide with embedded LED’s and sensors pads for interactive panels

December 02, 2016 // By Stadium IGT.
Thin film printed light-guides patented by Design LED Products Ltd, co-developed and manufactured under licence by Stadium IGT use specialised printing processes for the accomplishment of light extraction from the light-guide surface using side emitting LED’s embedded within the light-guide structure. In this advanced technology, the light extraction from the light-guide is determined by the size and location of printed micro lenses, achieving luminance uniformity >70%. The LED circuit can range from a mechanically flexible construction, nominally <1.2mm thick to a standard FR4 PCB.
