1. A modular light emitting diode (LED) display device comprising:

  • a first side and an opposite second side, wherein the first side of the modular LED display device comprises a display surface of the modular LED display device;

    a plastic housing comprisinga first dimension that is between six inches and four feet,a first recessed region, andan outer surface of the modular LED display device that is exposed to an external environment and being sealed to be waterproof, the outer surface being part of the opposite second side of the modular LED display device;

    a printed circuit board attached to the plastic housing, the printed circuit board comprising a first side and an opposite second side;

    a plurality of LEDs arranged as pixels attached to the first side of the printed circuit board, whereinthe pixels are arranged in an array of pixels comprising a plurality of rows and a plurality of columns,each pixel in the array of pixels is separated from adjacent pixels by a constant pixel pitch, andthe modular LED display device is configured to display images using the array of pixels;

    a compound overlying the first side of the printed circuit board, whereinthe first side of the printed circuit board is sealed to be waterproof by the compound, andthe modular LED display device is configured to be exposed to the external environment without additional enclosures;

    a circuit for controlling the plurality of LEDs, the circuit being attached to the opposite second side of the printed circuit board, wherein the circuit is disposed in the first recessed region of the plastic housing;

    a power supply for powering the plurality of LEDs, the power supply comprising a power converter for converting alternating current (AC) power to direct current (DC) power;

    a thermally conductive material thermally contacting both the power supply and the plastic housing;

    a framework of louvers disposed over the first side of the printed circuit board, the framework of louvers being disposed between the plurality of rows; and

    coupling structures, whereinthe modular LED display device is configured to be to be modularly attached with other modular LED display devices using the coupling structures to form an integrated display surface, andthe modular LED display device is configured to operate with the other modular LED display devices to display a single image on the integrated display surface.
