1. A display device comprising:
an enclosure comprising a front portion, a rear portion, and sides;
a halo comprising a rim and an internal structure, wherein the rim is positioned between the front portion and the rear portion and the internal structure of the halo is at least partially within the enclosure; and
a circuit board comprising light emitting devices mounted to a planar surface of the circuit board, the planar surface being parallel to the front portion and wherein a light path of a light leaving the light emitting devices and entering the internal structure of the halo is perpendicular to the planar surface and is turned to the rim by the internal structure, the rim extending directly between and sandwiched between surfaces of the front portion and the rear portion in an outwards direction that is parallel with the planar surface of the circuit board past an edge of the circuit board, the rim defining an end of the halo configured to emit the light out of the sides of the enclosure to an exterior of the enclosure along at least an emitting light path that is parallel with the planar surface of the circuit board, the light and the end of the halo configured to be viewed by an observer facing the side of the display device and a distance from the display device along a direction parallel with the planar surface of the circuit board.
