Optintegral Project (IMAGE) VTT Technical Research Centre of Finland Caption In the Optintegral project, a flexible, thin and transparent light panel was developed by integrating a flexible LED foil with a plastic, overmoulded structure. Optical features were added to the panel surface during the overmoulding, which focused light from the LEDs in the desired direction.
