Abstract

Embodiments of the present invention relate to integrated modular display systems. In one embodiment, a modular multi-panel display system includes a mechanical support structure, and a plurality of display panels detachably mounted to the mechanical support structure so as to form an integrated display panel. Each LED panel includes an LED array and an LED driver coupled to the LED array. Each panel further includes a power supply unit disposed outside the housing and electrically coupled to the receiver circuit. The mechanical structure is configured to provide mechanical support to the plurality of display panels without providing hermetic sealing. Each of the plurality of display panels is hermetically sealed.

Claims

1. A method of assembling a modular multi-panel display system, the method comprising:

assembling a plurality of mechanical support structures that each include a plurality of beams;

mounting a plurality of display panels to the plurality of beams of each of the plurality of mechanical support so as to assemble a plurality of integrated display panel sub-assemblies, each sub-assembly including a plurality of display panels arranged in rows and columns, wherein each of the display panels is sealed to be waterproof, and wherein each of the display panels includes

an array of display elements arranged in a plurality of rows and a plurality of columns to form a display panel surface,

a power supply electrically coupled to the receiver circuit and the display driver, wherein the power supply is configured to convert an alternative current (AC) received at an input and output a direct current (DC);

shipping the sub-assemblies to a second location remote from a location at which the sub-assemblies were assembled; and

at the second location, building a multi-panel display system by assembling the sub-assemblies into a 14×

48 or larger panel display, the multi-panel display system including an outer frame with a top beam, a bottom beam, a left outside beam, and a right outside beam and a plurality of vertical beams extending from the top beam to the bottom beam within the outer frame, each of the vertical beams having a smaller diameter and weighing less than any beam of the outer frame, wherein the multi-panel display system include no cabinets, is cooled passively and includes no air conditioning, fans, or heating units.

2. The method of claim 1, wherein the mechanical support structure is assembled so that the outer frame extends within a first vertical plane and the vertical beams extend in a second vertical plane laterally spaced from the first vertical plane.

3. The method of claim 1, wherein mounting the display panels comprises mounting each display panel to a respective beam using corner plates and wherein each display panel within an interior portion of the multi-panel display system is attached to two respective beams by four of the corner plates, each corner plate being mechanically connected to corners of four of the display panels to secure the display panels to the respective vertical beam.

4. The method of claim 1, further comprising mounting a data receiver box to the mechanical support structure, the data receiver box configured to provide power, data, and communication to the plurality of display panels.

5. The method of claim 1, wherein each display panel in each row is daisy-chain coupled to an adjacent display panel by a data cable.

6. The method of claim 5, wherein each display panel of each row is electrically coupled the adjacent panel through a respective integrated data and power cable, each integrated data and power cable comprising a plurality of male connectors surrounded by an end enclosure and a plurality of female connectors surrounded by the end enclosure, wherein each male connector is configured to fit into a female connector and each female connector is configured to receive a male connector, wherein the plurality of male connectors comprises three pins coupled to the power supply, wherein the plurality of female connectors are configured to carry data to the receiver circuit, and wherein the integrated data and power connector is configured to be waterproof when connected to another connector.
