Modular display panel

A modular light emitting diode (LED) display panel comprising:

• a printed circuit board;
• a plurality of LEDs arranged as pixels and attached to a front side of the printed circuit board, wherein the pixels are arranged in a rectangular array comprising at least fifty pixels;
• a framework of louvers disposed over the front side of the printed circuit board between rows of the LEDs, wherein the framework of louvers comprises a front outer surface of the modular LED display panel;
• a plastic casing comprising a back outer surface of the modular LED display panel;
• circuitry for controlling the plurality of LEDs, the circuitry being disposed in a recess of the plastic casing and attached to a back side of the printed circuit board, wherein the front side is opposite the back side;
• a power supply for powering the LEDs, the power supply being mounted on the back outer surface of the plastic casing, wherein the power supply comprises an alternating current/direct current (AC/DC) converter;
• wherein the modular LED display panel is sealed to be waterproof;
• wherein the modular LED display panel is configured to be exposed to an external environment without a protective waterproof enclosure;
• wherein the modular LED display panel is configured to be cooled passively without fans;
• and
• wherein the modular LED display panel is configured to be modularly assembled as part of a larger display.

A modular light emitting diode (LED) display panel comprising:

• a first side and an opposite second side, wherein the first side of the modular LED display panel comprises a display surface of the modular LED display panel;
• coupling structures for use in attachment as part of a multi-panel modular display, the coupling structures being disposed on the opposite second side of the modular display panel;
• a printed circuit board comprising a front side and an opposite back side;
• a plurality of LEDs arranged as pixels and attached to the front side of the printed circuit board, wherein the pixels are arranged in a rectangular array comprising at least fifty pixels;
• a casing disposed over the opposite back side of the printed circuit board, wherein the casing comprises plastic sidewalls and an outer surface of the modular display panel, the outer surface being part of the opposite second side of the modular display panel;
• an air gap disposed in a recess of the casing between the opposite back side of the printed circuit board and the casing;
• a circuit for controlling the plurality of LEDs, the circuit being attached to the printed circuit board and disposed in the recess of the casing;
