LED-Based Micro Display for an Intraocular Vision Aid (IOVA)

Abstract

In this Paper a micro display for an intraocular vision aid (IOVA) projecting an image of the environment onto the retina is presented, The display comprises an image of an array made out of single LED pixels, It is connected to a CMOS driver circuit using flip-chip technique, Since micro lenses have to be integrated into the substrate material for proper image projection onto the retina the generated light has to pass the substrate, Thus, only semiconductors with adequate large band gap energies are suitable, This paper discusses the principle of GaAsP material systems for an LED-based micro display applied to an implantable vision aid.
