Claim of US Patent No. 10,660,225

1. A display module comprising:a module support structure;
a plurality of light-emitting elements mounted to the front face of the module support structure; and
one or more latch assemblies configured to selectively removably couple the module support structure to a support chassis, wherein each of the one or more latch assemblies comprises;
a latch plate comprising a magnetically-engageable material, wherein the latch plate is movable relative to the module support structure within a range of motion between a first plate position and a second plate position;
wherein the magnetically-engageable material of the latch plate forms a first magnetic attraction force between the latch plate and a mating structure coupled to the support chassis when the latch plate is in the first plate position, wherein the first magnetic attraction force at least partially magnetically secures the display module to the support chassis proximate to the latch assembly when the latch plate is in the first plate position, and
wherein a corresponding magnetic device can generate a second magnetic attraction force between the corresponding magnetic device and the latch plate that overcomes the first magnetic attraction force and moves the latch plate from the first plate position to the second plate position.
