Modular display panel
DC CAFCFirst Claim
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,wherein the casing contacts the opposite second side of the printed circuit board,wherein the casing comprises sidewalls and a back surface,wherein the back surface of the casing comprises an outer back surface of the panel, andwherein the sidewalls of the casing comprise plastic;
a driver circuit disposed in the casing at the opposite second side of the printed circuit board, the driver circuit electrically coupled to the printed circuit board;
a plurality of LEDs attached to the first side of the printed circuit board;
a power supply for powering the plurality of LEDs, the printed circuit board being disposed between the power supply and the plurality of LEDs, wherein the power supply comprises a power converter for converting alternating current (AC) power to direct current (DC) power;
a heat conducting structure disposed between the power supply and the back surface of the casing;
a plurality of louvers attached to the first side of the printed circuit board;
a potting material disposed at the first side of the printed circuit board; and
wherein the modular display panel is sealed to be waterproof.

Abstract
Embodiments of the present invention relate to modular display panels. In one embodiment, a modular display panel includes a printed circuit board, a shell, a plurality of LEDs, a power supply, and a heat conducting structure. The LEDs are attached to a first side of the printed circuit board. The shell contacts an opposite second side of the printed circuit board. The shell includes a back surface that includes an outer back surface of the panel. A driver circuit is disposed in the shell. The sidewalls of the shell include plastic. The printed circuit board is disposed between the power supply and the LEDs. The power supply includes a power converter for converting alternating current (AC) power to direct current (DC) power. The heat conducting structure is disposed between the power supply and the back surface of the shell. The modular display panel is sealed to be waterproof.
