Abstract
A bottom emission microLED display includes a microLED disposed above a transparent substrate; a light guiding layer surrounding the microLED to controllably guide light generated by the microLED towards the transparent substrate; and a reflecting layer formed over the light guiding layer to reflect the light generated by the microLED downwards and to confine the light generated by the microLED to prevent the light from leaking upwards or sidewards.
