VTT Technical Research Centre of Finland has, for the first time, performed all manufacturing stages for a flexible in-moulded LED foil -in roll-to-roll process. The purpose of this demo is to prove the suitability of the technique for the highly cost-effective manufacture of products such as flexible LED displays containing printed electronics.

All smart electronics in products such as wrist-wearable computers are on a rigid board under the face of the watch. The roll-to-roll technique enables electronics to be printed on a plastic or elastomeric foil, which has various benefits such as thinness, lightness, elasticity and transparency. In hybrid-integrated systems, separate components are mounted on a printed electronic foil, after which the foil can be overmolded with thermoplastic or thermoplastic elastomer, using the injection moulding process … (click to read more)
