Display device, door including the same, and refrigerator including the door
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.
1. A display device comprising:
a frame rotatably mounted to a base object;
a display panel mounted to the frame;
a sensor configured to output a signal; and
a processor configured to identify whether the base object is in contact with the frame and a noise signal is generated due to an external force, based on the signal received from the sensor, and control the display panel to become transparent according to the identification.
2. The display device according to claim 1 , wherein the sensor comprises at least one of an acceleration sensor, a gyro sensor, and a geomagnetic sensor.
3. The display device according to claim 2 , wherein, in response to the frame being in contact with the base object, the sensor outputs an impact signal corresponding to impact between the frame and the base object.
4. The display device according to claim 3 , wherein the processor is configured to determine the frame is in an opening state or in a closing state based on the impact signal, and
wherein the opening state indicates that the frame is moving away from the base object, and the closing state indicates that the frame is moving closer to the base object.
5. The display device according to claim 4 , wherein the processor is configured to control a backlight unit of the display panel to be dimmed in response to determining that the frame is in the opening state.
6. The display device according to claim 4 , wherein the processor is configured to control a backlight unit of the display panel to be turned off in response to determining that the frame is in the opening state.
7. The display device according to claim 1 , wherein the sensor comprises an inductance sensor,
wherein the processor is configured to determine the frame is in an opening state when an inductance value indicated by the signal increases, and determine the frame is in a closing state when the inductance value decreases, and
wherein the opening state indicates that the frame is moving away from the base object, and the closing state indicates that the frame is moving closer to the base object.
8. The display device according to claim 1 , wherein the processor is configured to change a first image displayed on the display panel to a second image based on the signal.
9. The display device according to claim 1 , wherein the processor is configured to control a backlight unit of the display panel to increase brightness according to the identification.
