Summary:In a general aspect, a wearable display system includes a microlens array projector including a plurality of elemental microlens relays (EMRs). Each EMR of the plurality of EMRs includes a microLED microdisplay including a plurality of pixels, and is configured to generate a subset of light associated with an image. Each EMR also includes a microlens configured to receive the subset of light from the microdisplay. The system also includes a lightguide, an incoupling element optically coupled with the lightguide, and an outcoupling element optically coupled with the lightguide. The microlens is configured to relay the subset of light to the incoupling element. The incoupling element is configured to incouple the subset of light into the lightguide. The outcoupling element is configured to outcouple portions of the subset of light at a plurality of respective locations along the lightguide, where outcoupled light of the plurality of EMRs represents the image.
