Abstract

A lightweight display includes a plurality of display modules having a plurality of pixels carried by a display mounting frame. A support frame integral with the display mounting frame provides support. An electronic support member carries electrical components electrically communicating with the plurality of display modules for controlling the display of an image. Wherein the depth of the plurality of display modules, display mounting frame, support frame and electronic support member is less than four inches when defining a display assembly. Also wherein the display assembly has a screen size measured diagonally in a range of 114 inches to 224 inches and a weight in the range of 90 pounds to 120 pounds and wherein the display assembly has an aspect ratio ranging from 1.67 to 1.82.

Claims

1. A lightweight display comprising:

(a) a plurality of display modules having a similar area, each display module comprising a plurality of light emitting pixel chips provided on a flexible display substrate, said light emitting pixel chips being arranged in a pattern having uniform pixel spacing, wherein none or more of said display modules flexes to conform to a display module mounting frame;

(b) said display module mounting frame having a plurality of receptacles for receiving said plurality of display modules, said display module mounting frame having a front surface for carrying said display modules and a rear surface, said display module having a perimeter extending beyond the profile of said display module mounting frame when carried by said display module mounting frame;

wherein said display modules are carried by said display module mounting frame utilizing magnetic attraction;

(c) a support frame integrated with the rear surface of said display module mounting frame;

(d) an electronic support member carrying a plurality of electronic control circuits, said electronic control circuits in electrical connection with said display modules for controlling the transmission of display signals for the establishment of a display by said display modules, said electronic support member having a perimeter; and

(e) an outer frame having a first receptacle for receiving said perimeter of said display module mounting frame and a second receptacle for receiving said perimeter of said electronic support member.

2. The lightweight display of claim 1 wherein each display module includes an alignment device and said display module mounting frame have a plurality of alignment devices which work in conjunction with said alignment device of said display modules for aligning the attachment of said display modules with said display module mounting frame.

3. The lightweight display of claim 2 wherein said alignment device consists of a plurality of posts which are received within a post aperture carried by said display module mounting frame.

4. The lightweight display of claim 1 wherein said display modules carry a magnet and wherein said display mounting frame caries a metallic device for carrying said display module.

5. The lightweight display of claim 1 wherein said display modules carry a metallic device and wherein said display mounting frame caries a magnet for carrying said display module.

6. The lightweight display of claim 1 wherein said support frame carries a mounting bracket.

7. The lightweight display of claim 6 wherein said electronic support member includes at least one aperture exposing said mounting bracket to the ambient environment and wherein a respective display module may be removed from said display mounting frame exposing said mounting bracket.

8. The lightweight display of claim 6 wherein said outer frame includes a receptacle aligned with said mounting bracket enabling a vertically positioned fastener to be received via said receptacle for attachment with said mounting bracket enabling said display to be vertically mounted utilizing said support frame.

9. The lightweight display of claim 8 wherein said mounting bracket has a first set of fastener receptacles for horizontally receiving a fastener and a second set of fastener receptacles for vertically receiving a fastener thus enabling said lightweight display to be mounted either horizontally or vertically.

10. The lightweight display of claim 1 wherein said display modules have a pixel density wherein the gap between adjacent pixels both vertically and horizontally is equivalent for all display modules and wherein the spacing between adjacent pixels of adjacent display modules is equivalent to the spacing of pixels on a singular board.

11. The lightweight display of claim 1 wherein said display module mounting frame is of a height greater than said electronic support member and said outer frame member is curved for matingly engagement with said display module mounting frame and said electronic support member.

12. A lightweight display comprising:

(a) a plurality of display modules carried by a display mounting frame, each display module comprising a plurality of light emitting pixel chips;

wherein said display modules are carried by said display module mounting frame utilizing magnetic attraction;

(b) a support frame integral with said display mounting frame providing support;

(c) an electronic support member carrying electrical components electrically communicating with said plurality of display modules for controlling the display of an image;

(d) wherein the depth of said plurality of display modules, display mounting frame, support frame and electronic support member is less than four inches when defining a display assembly.

13. The display of claim 12 wherein said display assembly has a screen size measured diagonally in a range of 114 inches to 224 inches and said display assembly has an aspect ratio ranging from 1.67 to 1.82.

14. The display of claim 12 including an external frame having a curved profile and matingly attaching to said display mounting frame and said electronic support member.

15. The display of claim 14 wherein said support frame and said external frame define an interior and wherein said external frame includes a plurality of corner pieces designed for mating attachment with said interior of said external frame comprised of horizontal and vertical frame components.

16. The display of claim 12 wherein said pixels of said display modules have a predetermined pixel gap between adjacent vertical and horizontal pixels on a singular display board and wherein said predetermined pixel gap is also present between adjacent vertical and horizontal pixels on adjacent display boards.
