Abstract
A transparent optical module system or device comprising an optical architecture hierarchy based on a patch unit. In aspects, the transparent optical module comprises a display sparsely populated with pixels. The patch unit comprises one or more regions of display pixels, or a pixel pattern(s), and an associated lenslet, for example on a microlens array. The lenslet is capable of transmitting display-emitted light to an eye of the wearer of the transparent optical module, which then focuses the light to form a retinal image, which is seen or perceived by the wearer. The patch units can be combined further into patch groups, wherein members of a group serve a similar role in retinal image production as a patch unit and/or lenslet. This hierarchy allows the system to be scaled to larger and more complex systems.
