Display apparatus and method for controlling a screen of display apparatus
A display apparatus and a method for controlling a display apparatus are provided. The display apparatus includes a detector configured to detect a user motion; a display; a power supplier; a communicator configured to receive control information from a remote control device; and a controller configured to control the detector, the display, the power supplier, and the communicator, to control the display to display a preset screen on a part of the display in response to a user motion detected by the detector and first control information received from the remote control device, and to control the display to display content in response to second control information received from the remote control device.
1. A display apparatus comprising:
a sensor configured to sense a user motion;
a display;
a power supplier;
a transceiver configured to receive control information from a remote control device; and
a controller configured to control the sensor, the display, the power supplier, and the transceiver,
wherein the controller is further configured to:
based on the user motion being sensed by the sensor, shift a state of the display apparatus from a power off mode to a pre-power on mode,
based on first control information, that corresponds to a motion of the remote control device while the display apparatus is in the pre-power on mode, being received from the remote control device, control the display to display a predetermined screen on a portion of the display, and
based on second control information received from the remote control device, control the display to display content on a whole of the display.
2. The display apparatus as claimed in claim 1 , wherein in the pre-power on mode, the controller is further configured to control the power supplier to supply power to each component of the display apparatus except the display.
3. The display apparatus as claimed in claim 1 , wherein the first control information is received via one of the transceiver and an optical receiver.
4. The display apparatus as claimed in claim 1 , wherein based on receipt of the first control information, the controller is further configured to control the power supplier to supply power to the display of the display apparatus.
5. The display apparatus as claimed in claim 1 , wherein the controller is further configured to control the display to display the predetermined screen on a part of an area of the display to which power is supplied.
6. The display apparatus as claimed in claim 5 , wherein the controller is further configured to control the power supplier to provide power which is different from the power provided for displaying the predetermined screen to a rest of an area of the display.
7. The display apparatus as claimed in claim 1 , further comprising an audio outputter configured to output audio, wherein based on receipt of the first control information, the controller is further configured to control the power supplier to supply power to the audio outputter, and to control to output auditory feedback to the audio outputter.
8. The display apparatus as claimed in claim 1 , wherein the second control information is received via one of the transceiver and an optical receiver.
9. The display apparatus as claimed in claim 1 , wherein the controller is further configured to control the power supplier to continuously provide power to the sensor when power is not being supplied to the display.
10. The display apparatus as claimed in claim 1 , wherein the controller comprises a main processor and a sub processor, and the sensor is controlled by the sub processor.
11. A method for controlling a display apparatus, the method comprising:
based on sensing user motion, by a sensor configured to sense the user motion, shifting a state of the display apparatus from a power off mode to a pre-power on mode;
based on receiving first control information that corresponds to a motion of the remote control device from the remote control device, displaying a predetermined screen that corresponds to a motion of the remote control device on a portion of a display of the display apparatus while the display apparatus is in the pre-power on mode; and
based on receiving second control information from the remote control device, displaying content on a whole of the display apparatus.
12. The method of claim 11 , further comprising:
when the display apparatus operates in a welcome mode, supplying a first amount of power to a display of the display apparatus; and
when the display apparatus operates in a normal operational mode, supplying a second amount of power to the display of the display apparatus, wherein the second amount of power is greater than the first amount of power.
13. The method of claim 12 , wherein when the first amount of power is supplied to the display, a portion of the display receives the first amount of power such that a remaining portion of the display does not receive power.
14. The method of claim 13 , wherein when the second amount of power is supplied to the display, an entirety of the display receives power.
15. The method of claim 11 , wherein when the display apparatus operates in a welcome mode, the method further comprises displaying a stored image in the display apparatus and when the display apparatus operates in a normal operational mode, the method further comprises displaying at least one content received from an external source.
