1. A display device comprising:
- a frame configured to be rotatably mountable to a base object;
a display panel mounted to the frame;
a detector disposed in the frame, and configured to detect a movement of the frame and output a signal corresponding to the movement; and
a controller configured to;
identify a movement state of the frame based on the signal output by the detector, andcontrol the display panel to display different images based on the identified movement state of the frame,wherein the movement state of the frame includes a completely opened state, a completely closed state, and an ongoing state indicating that the frame is between the completely opened state and the completely closed state, andwherein, based on the movement state of the frame being the completely closed state, the controller is further configured to identify whether the signal output by the detector is an impact signal caused by closure of the frame or a noise signal caused by external force.

Abstract
A display device, a door including the display device and a refrigerator including the door are provided. A display device includes: a frame configured to be rotatably mounted to a base object; a display panel mounted to the frame; a detector disposed in the frame, and configured to detect a movement of the frame and output a signal corresponding to the movement; and a controller configured to determine a movement state of the frame based on the signal, and control the display panel based on the movement state.

7. A refrigerator comprising:
-
a main body comprising a storage chamber and an opening; and a door rotatably mounted to the main body to open or close the opening, wherein the door comprises; a frame; a display panel mounted to the frame; a detector disposed in the frame, and configured to detect a movement of the door and output a signal corresponding to the movement; and a controller configured to identify a movement state of the frame based on the signal output from the detector, and control the display panel based on the movement state, wherein the movement state of the frame includes a complete state and an ongoing state, wherein the complete state includes a completely opened state and a completely closed state, and the ongoing state indicates that the frame is between the completely opened state and the completely closed state, and wherein the controller is further configured to control the display panel to operate differently based on whether the frame is in the completely opened state or in the ongoing state. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A door comprising:
-
a frame configured to be rotatably mountable to a base object; a display panel mounted to the frame; a detector disposed in the frame, and configured to detect a movement of the frame and output a signal corresponding to the movement; and a controller configured to identify a movement state of the frame and a direction of the movement based on the signal, identify whether the door is in a currently opening state or in a currently closing state based on the identified direction, and control at least one of a transparency and displayed image of the display panel based on whether the door is in the currently opening state or in the currently closing state, wherein the movement state of the frame includes a complete state and an ongoing state, the ongoing state including the currently opening state and the currently closing state, wherein the complete state includes a completely opened state and a completely closed state, and the ongoing state indicates that the frame is between the completely opened state and the completely closed state, wherein the controller is further configured to control the display panel to operate differently based on whether the frame is in the completely opened state or in the ongoing state, and wherein the currently opening state indicates that the frame is moving away from the base object, and the currently closing state indicates that the frame is moving closer to the base object.
