Abstract

Embodiments of the present invention relate to integrated modular display panels. In one embodiment, modular display panel includes a casing having a recess. The casing includes locking points for use in attachment to an adjacent casing of another modular display panel. A printed circuit board is disposed in the recess and a plurality of LEDs attached to the printed circuit board. A driver circuit is attached to the printed circuit board. A heat sink is disposed between a back side of the casing and the printed circuit board. The heat sink thermally contacts the back side of the casing and the printed circuit board. A framework of louvers is disposed over the printed circuit board. The framework of louvers is disposed between rows of the LEDs. The framework of louvers is attached to the printed circuit board using an adhesive.
