Abstract
A display apparatus includes a transparent substrate having first and second sides, an array of LED micro-display panels, and an array of collimating reflectors. The LED micro-display panels are disposed within the transparent substrate between the first and second sides and oriented to emit sub-image portions of a display image towards the first side. The collimating reflectors are disposed within the transparent substrate between the first side and the array of LED micro-display panels. The collimating reflectors are aligned with the LED micro-display panels to reflect the sub-image portions back out the second side of the transparent substrate. The LED micro-display panels are offset from the collimating reflectors to expand the sub-image portions prior to reflection by the collimating reflectors.
