Abstract
An image generator for use in a display device, the image generator comprising a plurality of ILED array chips each comprising a plurality of ILED emitters and arranged in an array such that each of a plurality of pixels of the image generator comprises an ILED emitter from each of a plurality of adjacent ILED array chips. The total area of ILED emitter material be less than 50% of the area of each pixel. The image generator may comprise secondary optics in optical communication with an output of the plurality of ILED emitters of an ILED array chip and configured to direct light from the ILED emitters towards an emission region of the associated pixel.
