Abstract

A vehicular display assembly includes a pixelated display having a plurality of micro-LEDs disposed at a substrate. Packing density of micro-LEDs of the plurality of micro-LEDs at the substrate is at least 10 micro-LEDs per square centimeter. Each individual micro-LED of the plurality of micro-LEDs, when the vehicular display assembly is operated to emit light, may pass less than 4 mA electrical current. The vehicular display assembly is configured to be disposed at a portion of a vehicle equipped with the vehicular display assembly. With the vehicular display assembly disposed at the portion of the equipped vehicle, light emitted by the plurality of micro-LEDs, when the vehicular display assembly is operated to emit light, is viewable at the portion of the equipped vehicle.
