Abstract
A micro light-emitting diode (LED) display assembly includes a backplane, a passivation layer on the backplane, a micro LED on the passivation layer, and a non-transparent metal housing on the passivation layer. The housing includes a base portion on the passivation layer, a sidewall portion upwardly extending from the base portion, a cap portion connected at a top of the sidewall portion, an orifice in the cap portion, and a notch in the cap portion and adjacent to the orifice. The assembly also includes a translucent filter positioned in the notch and covering the orifice, and a pocket defined by an enclosed area in between the sidewall portion, the cap portion, the filter, and the passivation layer. The micro LED is encased within the pocket such that light transmitted from the micro LED directly hits and passes through the filter.
