Abstract

Display module mounting apparatus and methods provide mounting features enabling ease of installation and service. The apparatus may have one or more releasable frame couplers and pivoting releasable frame couplers coupled to a display module having a display plane defined in relation to a substrate. One or more adjustable linkages may adjustably define a standoff distance between the display plane and a support frame to which the module may be mounted by the mounting apparatus. Concave and convex adjustments to the display plane may be made. Operation of pivoting action to tilt the display plane enables installation, removal, and serviceability of large displays constructed with a tiled plurality of display modules.

First claim

The invention claimed is:

1. A display apparatus, mountable to a support frame, said apparatus comprising:
a) a display module comprising a plurality of light emitting elements coupled to a flexible substrate, said plurality of light emitting elements arranged in a predetermined pattern forming a display plane;
b) a plurality of releasable frame couplers coupled to said flexible substrate, each of said releasable frame couplers providing a standoff distance between said display plane and said support frame;
c) at least two of said plurality of releasable frame couplers being adjustable releasable frame couplers, each of said adjustable releasable frame couplers operative to provide, independently, an adjustable standoff distance between said display plane and said support frame;
d) the display module further characterized as having both an installed position and a service position, said installed position defined when said plurality of releasable frame couplers are all coupled to said support frame, said service position defined when at least one of said plurality of releasable frame couplers is not coupled to said support frame and at least one of said plurality of releasable frame couplers is coupled to said support frame;
e) said display module operative to pivot about one of said plurality of releasable frame couplers and thereby transition from said installed position to said service position;
f) the apparatus further comprising an adjustable linkage coupled at two different locations to said display plane, said adjustable linkage operative to provide an adjustable deflection of at least a portion of said display plane;
g) the apparatus further characterized in that the adjustable linkage is operable to provide an adjustable concave deflection of at least a portion of said display plane.

2. A display apparatus, mountable to a support frame, said apparatus comprising:
a) a display module comprising a plurality of light emitting elements coupled to a flexible substrate, said plurality of light emitting elements arranged in a predetermined pattern forming a display plane;
b) a plurality of releasable frame couplers coupled to said flexible substrate, each of said releasable frame couplers providing a standoff distance between said display plane and said support frame;
c) at least two of said plurality of releasable frame couplers being adjustable releasable frame couplers, each of said adjustable releasable frame couplers operative to provide, independently, an adjustable standoff distance between said display plane and said support frame;
d) the display module further characterized as having both an installed position and a service position, said installed position defined when said plurality of releasable frame couplers are all coupled to said support frame, said service position defined when at least one of said plurality of releasable frame couplers is not coupled to said support frame and at least one of said plurality of releasable frame couplers is coupled to said support frame;
e) said display module operative to pivot about one of said plurality of releasable frame couplers and thereby transition from said installed position to said service position;
f) the apparatus further comprising an adjustable linkage coupled at two different locations to said display plane, said adjustable linkage operative to provide an adjustable deflection of at least a portion of said display plane;
g) the apparatus further characterized in that the adjustable linkage is operable in to provide an adjustable convex deflection of at least a portion of said display plane.

3. A display system comprising:
a) a support frame operative to support the weight of a plurality of display modules along a support direction, and operative to comply with curvature of said support frame in directions orthogonal to said support direction;
b) each of said plurality of display modules comprising a plurality of light emitting elements coupled to a flexible substrate and arranged according to a predetermined pattern forming a display plane;
c) each of said plurality of display modules mounted to said support frame by a mounting apparatus comprising:
i) a plurality of releasable frame couplers coupled to said flexible substrate, each of said releasable frame couplers providing a standoff distance between said display plane and said support frame;
ii) at least two of said plurality of releasable frame couplers being adjustable releasable frame couplers, each of said adjustable releasable frame couplers operative to provide, independently, an adjustable standoff distance between said display plane and said support frame;
iii) an adjustable linkage coupled at two different locations to said display plane, said adjustable linkage operative to provide an adjustable deflection of at least a portion of said display plane, said deflection defining a curvature in a direction substantially orthogonal to said support direction.

4. The apparatus of claim 3 further characterized in that each of the plurality of display modules has both an installed position and a service position, said installed position defined when said plurality of releasable frame couplers are all coupled to said support frame, said service position defined when at least one of said plurality of releasable frame couplers is not coupled to said support frame and at least one of said plurality of releasable frame couplers is coupled to said support frame, the display module being further operative to pivot about one of said plurality of releasable frame couplers and thereby transition from said installed position to said service position.

5. The apparatus of claim 4 further characterized in that said display plane is disposed at a first angle with respect to support frame when in said installed position, a portion of said display plane being disposed at a second angle with respect to said support frame when in said service position; and wherein said first angle and said second angle are not equal.

6. The apparatus of claim 3 further characterized in that the plurality of releasable frame couplers couple to said support frame by means of magnetic attraction.
