Abstract
A display apparatus comprises an array of micro-LEDs and an aligned array of catadioptric optical elements wherein the array of micro optics is further aligned to an array of apertures of a low reflection screen. Advantageously such an arrangement provides a display with large images of configurable size, low cost and high brightness that can achieve high contrast in high illuminance from ambient lighting while also achieving high luminous efficiency.
