Magnetic latch for a display module

A latching system for removably coupling a display module to a support chassis, the latching system comprising:

• one or more magnet subassemblies each including;
• a first magnet movably coupleable to the display module at a first location, wherein the first magnet is movable relative to the display module between a first position and a second position,
• a second magnet movably coupled with the display module at a second location, and
• a connecting member disposed between the first location and the second location, wherein the connecting member connects the first magnet and the second magnet so that the first magnet and the second magnet move together such that the second magnet is in a first corresponding position when the first magnet is in the first position and is in a second corresponding position when the first magnet is in the second position;
• a corresponding third magnet attachable to the support chassis for each of the one or more magnet subassemblies, wherein the second magnet and the corresponding third magnet are proximate to each other when the display module is mounted to the support chassis, wherein a mounting magnetic force is formed between the second magnet and the fourth magnet when the second magnet is in the first corresponding position;
• and
• an actuation tool comprising a fourth magnet, wherein the actuation tool is positionable proximate to the first magnet of a magnet subassembly so that an actuation magnetic attraction is formed between the fourth magnet and the first magnet so that when the actuation tool is moved from an unlatched position toward a latched position the first magnet will move from the first position toward the second position, which will cause the second magnet to move from the first corresponding position toward the second corresponding position so that the mounting magnetic attraction is generated between the second magnet and the third magnet.

A method comprising:

• providing or receiving a display module comprising a module support structure and a latch assembly coupled to the module support structure, wherein the latch assembly comprises:
• a first magnet movably coupled to the module support structure at a first location, the first magnet being movable relative to the module support structure between a first position and a second position;
• a second magnet movably coupled with the module support structure at a second location, the second magnet being movable relative to the module support structure between an unlatched position and a latched position;
• and
• a shaft connecting the first magnet and the second magnet so that the first magnet and the second magnet move together such that the second magnet is in the unlatched position when the first magnet is in the first position and is in the latched position when the first magnet is in the second position;
• providing or receiving a support chassis comprising a third magnet attached thereto;
• positioning the display module so that the second magnet of the latch assembly is proximate to the third magnet;
• and
• moving the first magnet of the latch assembly from the first position to the second position so that the second magnet is moved from the unlatched position to the latched position so that a north pole of the second magnet is aligned with a south pole of the third magnet, or a south pole of the second magnet is aligned with a north pole of the third magnet, or both, so that a magnetic mounting force is formed between the second magnet of the latch assembly and the third magnet.
