Abstract
A method of fabricating an image generator for use in a display, the method comprising: fabricating a plurality of discrete ILED array chips comprising a plurality of ILED emitters configured to produce light having the same wavelength, and wherein each of the plurality of ILED array chips is configured to produce light having one of a plurality of wavelengths; positioning the plurality of discrete ILED array chips on a carrier substrate such that a plurality of ILED emitters from adjacent chips form a pixel of a display; and bonding a first surface of the plurality of ILED array chips to a driver backplane such that electrical contacts of the plurality of ILED array chips are in electrical communication with the driver backplane, wherein the driver backplane comprises electronics for driving the ILED array chips.
