Modular Display Panel

Abstract

Embodiments of the invention are related to modular display panels. In one embodiment, a modular display panel includes a first side which includes a display surface, and an opposite second side. The modular display panel further includes a plastic enclosure including an outer surface that forms substantially all of the second side. The modular display panel further includes LEDs arranged as pixels attached to a printed circuit board which is attached to the plastic enclosure. The modular display panel further includes a circuit for controlling the LEDs and a power source for powering the LEDs. The front side of the printed circuit board is sealed to be waterproof and the plastic enclosure is sealed to be waterproof so that the modular display panel is sealed to be waterproof.

1 . A modular display panel comprising:
 a printed circuit board having a first side and an opposite second side;   a casing comprising a thermally conductive material, the casing being disposed at the opposite second side of the printed circuit board, the casing contacting the opposite second side of the printed circuit board, the casing comprising plastic sidewalls and a plastic back wall substantially similar in area to the opposite second side of the printed circuit board, and the plastic back wall of the casing comprising a first outer surface of the modular display panel;   a plurality of light emitting diodes (LEDs) arranged as pixels and attached to the first side of the printed circuit board, the pixels being arranged in a rectangular array comprising at least fifty pixels;   a plural of louvers adjacent rows of the LEDs;   a power supply housing mounted over the first outer surface of the casing, the power supply housing comprising sidewalls, a front wall, and an opposing back wall that is a second outer surface of the modular display panel;   a power supply for powering the plurality of LEDs, the power supply being disposed in the power supply housing, the power supply comprising a power converter for converting alternating current (AC) power to direct current (DC) power, the power supply being fully enclosed with a combination of the sidewalls, front wall, and opposing back wall of the power supply housing, and both a first portion of the casing and a second portion of the power supply housing being disposed between the printed circuit board and the power supply; and   a heat conducting structure configured to extract heat disposed proximate to the power supply, the modular display panel being sealed to be waterproof, and the modular display panel is configured to be independently operable and configured to be integrated with other displays to form a larger display.
