  • Publication number: 20160076691
    Abstract: A display apparatus adaptable to being placed in different locations includes a frame, a display panel received in the frame, at least one rotating portion rotatably connected with the frame, and a base rotatably connected to the at least one rotating portion. The at least one rotating portion is parallel with a back surface of the frame. The base can be perpendicularly located under the frame to support the display apparatus in a first placing orientation, on a table for example, or the center of the base can be swung through 180 degrees to rest substantially flush against the back of the display panel when it is desired that the display apparatus be hung from a wall for example.

  • Publication number: 20160081208
    Abstract: A display apparatus can be placed in different orientations. The display apparatus includes a frame, a display panel received in the frame, a casing, a fixing portion, and at least one movable leg. The casing is mounted on the frame via a fixing portion. The frame and casing are pivotal relative one another between a first display orientation and a second display orientation. The at least movable leg changes from a first position on the frame when the frame and casing are in the first display orientation to a second position to cooperate with the casing and frame to place the frame and casing in the second display orientation.
