Abstract

Systems and devices describe an augmented-reality glasses having a plurality of panels of light emitters arranged to form an array of light emitters, collimation optics for collimating light received from the array of light emitters, an optical coupler for receiving the collimated light, and a waveguide for display of augmented-reality content to a wearer of the augmented-reality glasses. In some embodiments, the array of light emitters includes light emitters generating three colors, each panel of the plurality of panels of light emitters having light emitters generating a same color, and each panel of the plurality of panels of light emitters positioned on a surface of a semiconductor with at least one integrated circuit. The array of light emitters can be two-dimensional array of light emitters arranged on a common plane and characterized by a pitch that is less than 2 μm.
