Abstract

Disclosed are embodiments of flexible display modules and systems of flexible display modules. Display modules have a plurality of light emitting elements arranged in a predetermined pattern and providing a highly uniform visual effect. Alignment and complementary alignment features enable the alignment of adjacent display modules and the creation of large displays from a plurality of aligned display modules. Features to couple to and retain a support frame are provided. Flexible and durable weather resistance features are provided. Modules and systems have features that permit installation and removal from the front side or the back side of the display. A system of modular support frames works cooperatively with the display modules, adapting to different mounting environments, and thereby providing large modular displays with desirable properties.

First claim

We claim:

1. A method of providing a modular display system mounted on a support frame, the method comprising the steps of:
a) assembling a plurality of display modules to collectively create a viewing plane on which an image is viewable, displaying at least a portion of said image on each of said plurality of display modules, said viewing plane having no visual aberrations between adjacent display modules;
b) each of said plurality of display modules constructed according to the steps of:
i) electrically connecting a flexible substrate to a plurality of light emitting elements;
ii) disposing said plurality of light emitting elements on a display plane in a predetermined pattern;
iii) coupling a releasable frame retention means to said flexible substrate, said releasable frame retention means having a retaining position and a non-retaining position, said retaining position effective for engaging a portion of said support frame, said retaining position effective for urging said display plane to be substantially co-planar with said viewing plane, said non-retaining position allowing said first display module to be removed from said viewing plane;
iv) configuring said releasable frame retention means to be actuated between said retaining position and said non-retaining position from the display plane side of said display module;
v) coupling a first alignment feature to said flexible substrate and disposing said first alignment feature in a predetermined relationship to said display plane;
vi) coupling a first complementary alignment feature to said flexible substrate and disposing said first complementary alignment feature in a predetermined relationship to said first alignment feature;

c) coupling a structural member to said support frame in tension to create a curvature of at least a portion of said viewing plane;
d) the step of assembling a plurality of display modules further characterized in that:
i) each display module further characterized in that it has an installed position in which the releasable frame retention means is in said retaining position and said display plane is substantially co-planar with said viewing plane;
ii) said plurality of display modules comprises a first and a second display module in the installed position and disposed adjacent to each other;

e) engaging the first alignment feature of the first display module with the first complementary alignment feature of the second display module thereby causing said predetermined pattern of light emitting elements of said first display module to become aligned with the predetermined pattern of light emitting elements of the second display module, the alignment between said first and said second display modules causing no perceivable visual aberration on the viewing plane.

2. The method of claim 1 further characterized in that each light emitting element of said plurality of light emitting elements is disposed about a first pitch distance away from at least two closest adjacent light emitting elements, said pitch distance being uniform across said predetermined pattern.

3. The method of claim 1 further comprising the step of creating a constraint force that urges said predetermined pattern of said first display module to align with the predetermined pattern of said second display module when the first alignment feature of said first display module operatively engages the first complementary alignment feature of said second display module.

4. The method of claim 1 further comprising the step of configuring at least a portion of the viewing plane to follow a convex curve.

5. The method of claim 1 further comprising the step of configuring at least a portion of the viewing plane to follow a concave curve.

6. The method of claim 1 further comprising the step of configuring at least a portion of the viewing plane to be flat.

7. The method of claim 1 further comprising the steps of:
a) configuring the releasable frame retention means as a plurality of magnetic couplers disposed on a side of the display module that is opposite the display plane;
b) disposing said plurality of magnetic couplers being in a predetermined position with respect to the display plane;
c) configuring each display module of said plurality of display modules is to attract one or more ferromagnetic portions of said support frame by means of magnetic attraction between said magnetic couplers and said one or more ferromagnetic portions.

8. A method of providing a modular display system mounted on a support frame, the method comprising the steps of:
a) assembling a plurality of display modules to collectively create a viewing plane on which an image is viewable, displaying at least a portion of said image on each of said plurality of display modules, said viewing plane having no visual aberrations between adjacent display modules;
b) each of said plurality of display modules constructed according to the steps of:
i) electrically connecting a flexible substrate to a plurality of light emitting elements;
ii) disposing said plurality of light emitting elements on a display plane in a predetermined pattern;
iii) coupling a releasable frame retention means to said flexible substrate, said releasable frame retention means having a retaining position and a non-retaining position, said retaining position effective for engaging a portion of said support frame, said retaining position effective for urging said display plane to be substantially co-planar with said viewing plane, said non-retaining position allowing said first display module to be removed from said viewing plane;
iv) configuring said releasable frame retention means to be actuated between said retaining position and said non-retaining position from the display plane side of said display module;
v) coupling a first alignment feature to said flexible substrate and disposing said first alignment feature in a predetermined relationship to said display plane;
vi) coupling a first complementary alignment feature to said flexible substrate and disposing said first complementary alignment feature in a predetermined relationship to said first alignment feature;

c) coupling a structural member coupled to said support frame in compression to create a curvature of at least a portion of said viewing plane;
d) the step of assembling a plurality of display modules further characterized in that:
i) each display module further characterized in that it has an installed position in which the releasable frame retention means is in said retaining position and said display plane is substantially co-planar with said viewing plane;
ii) said plurality of display modules comprises a first and a second display module in the installed position and disposed adjacent to each other;

e) engaging the first alignment feature of the first display module with the first complementary alignment feature of the second display module thereby causing said predetermined pattern of light emitting elements of said first display module to become aligned with the predetermined pattern of light emitting elements of the second display module, the alignment between said first and said second display modules causing no perceivable visual aberration on the viewing plane.

9. The method of claim 8 further characterized in that each light emitting element of said plurality of light emitting elements is disposed about a first pitch distance away from at least two closest adjacent light emitting elements, said pitch distance being uniform across said predetermined pattern.

10. The method of claim 8 further comprising the step of creating a constraint force that urges said predetermined pattern of said first display module to align with the predetermi
