In one aspect, the disclosure relates to micro-LED based AR displays combining stacked red, green, and blue LEDs, distributed Bragg reflectors, and diffractive optics; methods of making the same; and augmented reality displays using the same. In one aspect, the light generated by the LEDs is reflected within the optical cavity of DBR/LED/DBR, creating a highly directional (5) and monochromatic (FWHM5nm) blue light. In an aspect, the luminance of the disclosed inorganic-based micro-LEDs is orders of magnitude higher than that of organic LEDs while also providing high directionality and monochromaticity, leading to higher image quality. In a further aspect, the small size of the disclosed light source and combiner allows a much more compact and light-weight AR device to be constructed.

Provided is a display apparatus that can suppress degradation of image quality caused by possible color drift. A display apparatus includes a board including a driving circuit based on a current amplitude modulation scheme, multiple first light emitting elements and multiple second light emitting elements two-dimensionally arranged on the board, and a wavelength correcting layer that is able to correct wavelengths of light emitted from the multiple first light emitting elements. The driving circuit is able to independently gamma-correct a first signal fed to the first light emitting element and a second signal fed to the second light emitting element.
