Abstract
Systems, devices, and methods for transparent displays that are well-suited for use in wearable heads-up displays are described. Such transparent displays include a light source that sequentially generates pixels or other discrete portions of an image. Respective modulated light signals corresponding to the respective pixels/portions are sequentially directed towards at least one dynamic reflector positioned on a lens of the transparent display within the user's field of view. The dynamic reflector (such as a MEMS-based digital micromirror) scans the modulated light signals directly over the user's eye and into the user's field of view. Successive portions of the image are generated in rapid succession until the entire image is displayed to the user.
