  • Publication number: 20250126731
    Abstract: A display device having a back cover coupled to a display panel and a stand cover rotatably coupled to the back cover. The device also includes an elastic member that extends in a direction that intersects the rotation axis of the stand cover. A follower shaft is coupled to the elastic member and is structured to be movable in a longitudinal direction. The stand cover includes a shaft extending toward the rotation axis and is structured to rotate about the rotation axis, and a cam integrally rotating with the shaft to move the follower shaft. The cam includes a ramp that contacts the follower shaft, and the ramp includes a nose protruding in a direction intersecting the rotation axis, where a distance between the nose and the rotation axis increases and then decreases as the stand cover is rotated about the rotation axis.
