Abstract
A micro-LED laser display having an array of display pixels includes a display substrate for displaying an image and an array of display pixels. Each display pixel has one or more micro-LED lasers disposed on the display substrate. Each micro-LED laser emits light within an emission angle. One or more light spreaders for increasing the emission angle of light emitted by each micro-LED laser are disposed in relation to the light spreaders and a controller individually controls the micro-LED lasers.
