A display module comprises a circuit board having a front face, a plurality of light-emitting elements electrically coupled to the front face of the circuit board, a polymer encapsulating member adhered to the front face of the circuit board, the polymer encapsulating member substantially covering at least a portion of the circuit board and a portion of the plurality of light-emitting elements, the polymer encapsulating member substantially sealing the portion of the circuit board and the portion of the plurality of light-emitting elements, and an ultraviolet-radiation diminishing component in the polymer encapsulating member or on one or more of at least a portion of the circuit board or at least a portion of each of the light-emitting elements, wherein the ultraviolet-radiation diminishing component filters, blocks, or reflects more ultraviolet radiation than would be filtered, blocked, or reflected by the polymer encapsulating member without the ultraviolet-radiation diminishing component.
