Abstract

Display module mounting configurations and methods are disclosed. A frame for a video display module can comprise a first face configured for coupling with a light-emitting element circuit board and a second face configured for mounting to a support chassis and one or more first securing structures coupled to the second face, the one or more first securing structures being configured to mount or secure the frame to the support chassis. The frame can also include one or more security latches each comprising a latch body movable between a latched position and an unlatched position, each latch body configured to engage a first feature of the support chassis to prevent removal of the video display module when in the latched position.

First claim

1 . A display system, comprising:
a display module including a first module face, a second module face, and a plurality of light-emitting elements mounted to the first module face; one or more first securing structures coupled to the display module to mount or secure the display module to one or more support structures; and a security latch coupled to the display module, the security latch comprising;
a latch body that moves relative to the display module between a latched position and an unlatched position, and
a biasing structure that creates a biasing force that biases the latch body in a biasing direction toward the latched position,
wherein the latch body comprises a ramped portion that engages an engagement surface on the one or more support structures, wherein the engagement between the engagement surface and the ramped portion exerts an unlatching force on the latch body to move the latch body in an unlatching direction that is substantially opposite to the biasing direction and to push against the biasing force to move the latch body to the unlatched position, and wherein, upon disengagement between the ramped portion and the engagement surface, the biasing force of the biasing structure moves the latch body in the biasing direction to the latched position so that the latch body engages a feature of the one or more support structures to prevent disengagement of the display module from the one or more support structures.

2 . The display system of claim 1 , wherein the security latch further comprises a mating structure that retains the latch body to maintain an alignment of the latch body relative to the display module during movement of the latch body between the latched position and the unlatched position.

3 . The display system of claim 2 , wherein the mating structure is mounted to the second module face.

4 . The display system of claim 1 , wherein the biasing structure comprises a spring.

5 . The display system of claim 4 , wherein the spring comprises an inner diameter and an outer diameter, and wherein the latch body comprises a portion configured to fit inside an inner diameter of the spring.

6 . The display system of claim 1 , wherein the latch body further comprises:
a front latch face facing toward the second module face and an opposing rear latch face; a second ramped portion extending at least partially between the front latch face and the rear latch face; and a channel extending from at least one of the front latch face and the rear latch face to permit access for a removal tool to exert a second unlatching force on the second ramped portion that moves the latch body in the unlatching direction to push against the biasing force and to move the latch body to the unlatched position.

7 . The display system of claim 6 , wherein the channel permits the removal tool access to the second ramped portion in a tool access direction that is substantially normal to the first module surface and the second module surface.

8 . The display system of claim 6 , wherein the display module further comprises a removal tool hole extending between the first module face and the second module face, wherein the removal tool hole is at least partially aligned with the channel, and wherein the removal tool hole receives the removal tool and allows the removal tool to access the channel and exert the second unlatching force on the second ramped portion.

9 . The display system of claim 1 , wherein the one or more first securing structures comprise at least one of: one or more magnets, one or more primary latches, one or more securing structures integral with the second module face, or one or more fasteners.

10 . The display system of claim 1 , wherein the security latch is actuable from a front side of the display module.

11 . The display system of claim 1 , wherein the latch body further comprises a handle that can be manipulated by a user to push the latch body against the biasing force and to move the latch body to the unlatched position.

12 . A method comprising:
providing or receiving a module assembly that includes:
a display module including a first module face, a second module face, and a plurality of light-emitting elements mounted to the first module face, and
a security latch coupled to the display module, the security latch comprising;
a latch body that moves relative to the display module between a latched position and an unlatched position, and
a biasing structure that creates a biasing force that biases the latch body in

a biasing direction toward the latched position:
mounting the module assembly to one or more support structures, wherein the mounting includes:
moving the module assembly so that the ramped portion engages an engagement surface on the one or more support structures such that the engagement surface pushes on the ramped portion to exert an pushing force on the latch body in an unlatching direction that is substantially opposite to the biasing direction and that counters the biasing force to move the latch body to the unlatched position,
while the latch body is in the unlatched position, moving the module assembly into a mounted position relative to the one or more support structures, wherein once the module assembly is in or proximate to the mounted position, the ramped portion becomes disengaged from the engagement surface so that the biasing force of the biasing structure moves the latch body in the biasing direction to the latched position so that the latch body engages a feature of the one or more support structures to prevent disengagement of the display module from the one or more support structures, and
securing the module assembly to the one or more support structures with one or more first securing structures.

13 . The method of claim 12 , further comprising, after mounting the module assembly to the one or more support structures, dismounting the module assembly from the one or more support structures, the dismounting comprising:
disengaging the one or more first securing structures from one or both of the module assembly or the one or more support structures. moving the latch body in the unlatching direction against the biasing force from the latched position to the unlatched position; and separating the module assembly from the one or more supporting structures.

14 . The method of claim 13 , wherein the latch body further comprises a handle, and wherein moving the latch body in the unlatching direction comprises manipulating the handle.

15 . The method of claim 13 , wherein the moving the latch body in the unlatching direction during the dismounting comprises engaging the latch body with a removal tool so that the removal tool moves the latch body in the unlatching direction from the latched position to the unlatched position.

16 . The method of claim 15 , wherein the latch body further comprises a front latch face facing toward the second module face and an opposing rear latch face, a second ramped portion extending at least partially between the front latch face and the rear latch face, and a channel extending from at least one of the front latch face and the rear ramped face; and
wherein the moving the latch body in the unlatching direction during the dismounting includes inserting at least a portion of the removal tool into the channel and exerting the second unlatching force onto the second ramped portion with the removal tool.

17 . The method of claim 16 , wherein the display module further comprises a removal tool hole extending between the first module face and the second module face, wherein
