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.

A display device, comprising:
- a first inorganic light emitting diode (ILED) array chip including first ILED emitters each providing a subpixel for a different pixel of the display device;
- and
- a second ILED array chip including second ILED emitters each providing a subpixel for a different pixel of the display device, the first and second ILED array chips arranged such that a pixel of the display device includes a first ILED emitter from the first ILED array chip and a second ILED emitter from the second ILED array chip.
