LED-display for an intraocular microoptic system.
In this paper the design and fabrication of an LED array usable for an intraocular vision aid (IOVA) is presented. IOVA is intended for people with vastly opaque cornea caused by explosion or chemical burns. The LED array consists of 1024 single GaP/GaAsP LEDs. In a first step an 8 x 8 pixel LED array has been fabricated. This LED array is bonded to a CMOS driver circuit performing a miniaturized display by using flip-chip-technique. Thus each LED pixel can be driven separately and the generated light passes the substrate.
