Abstract
Embodiments of the present invention relate to integrated modular display panels. In one embodiment, modular display panel includes a shell with a first thermally conductive material, a printed circuit board disposed in the shell, and a plurality of LEDs attached to a first side of the printed circuit board. A driver circuit is disposed in the shell and coupled to the plurality of LEDs from a second side of the printed circuit board. The panel further includes a power supply unit for powering the LEDs. The printed circuit board are disposed between the power supply unit and the plurality of LEDs. A second thermally conductive material is disposed between the power supply unit and an outer back side of the panel. A protective structure is disposed over the first side of the printed circuit board, where a display side of the panel, opposite the outer back side, is waterproof.
