Abstract

A display apparatus is provided that including a display configured to display content. The display apparatus also includes a main controller configured to control operation of the display, a power supplier configured to supply power to operate the display and the main controller, a power measurer configured to measure the power supplied by the power supplier, a storage configured to store information regarding a third power range which is between a first power range that the display apparatus consumes in a sleep state and a second power range that the display apparatus consumes in a normal state, and a power controller configured to cut off the power supplied by the power supplier in response to the measured power being within the third power range.

Claims

1. A display apparatus comprising:

a display configured to display content;

a main controller configured to control operation of the display;

a power supplier configured to supply power to operate the display and the main controller;

a power measurer configured to measure the power supplied by the power supplier;

a storage configured to store information regarding a third power range which is between a first power range that the display apparatus consumes in a sleep state and a second power range that the display apparatus consumes in a normal state; and

a power controller configured to cut off the power supplied by the power supplier in response to the measured power being within the third power range.

2. The display apparatus as claimed in claim 1, further comprising:

a timer configured to measure a time elapsed from when the measured power is within the third power range,

wherein the power controller is further configured to cut off the power supplied by the power supplier in response to the time measured by the timer exceeding a critical time.

3. The display apparatus as claimed in claim 1, further comprising:

a switch configured to electrically connect the main controller and the power supplier,

wherein the power controller is further configured to turn off the switch to electrically disconnect the main controller and the power supplier in response to the measured power being within the third power range.

4. The display apparatus as claimed in claim 3,

wherein the first power range is measured when the display and the main controller are turned off,

wherein the second power range is measured when the display and the main controller are turned on, and

wherein the third power range is measured when the display is turned off and the main controller is turned on.

5. The display apparatus as claimed in claim 1, further comprising:

a camera configured to take a photograph,

wherein the third power range is a power range that the display apparatus consumes when the camera is activated.

6. The display apparatus as claimed in claim 5, further comprising:

a communicator configured to communicate with an external device,

wherein the third power range is a power range that the display apparatus consumes when the camera and the communicator are activated.

7. A control method of a display apparatus, the method comprising:

measuring power supplied to the display apparatus; and

cutting off the supplied power in response to the measured power being within a third power range which is between a first power range that the display apparatus consumes in a sleep state and a second power range that the display apparatus consumes in a normal state.

8. The method as claimed in claim 7, further comprising:

measuring a time elapsed from when the measured power is within the third power range,

wherein the cutting off the supplied power comprises cutting off the supplied power in response to the measured time exceeding a critical time.

9. The method as claimed in claim 7,

wherein the first power range is measured when a display configured to display content and a main controller configured to control the display are turned off,

wherein the second power range is measured when the display and the main controller are turned on, and

wherein the third power range is measured when the display is turned off and the main controller is turned on.

10. The method as claimed in claim 7, further comprising:

taking a photograph of an external object using a camera,

wherein the third power range is a power range that the display apparatus consumes when the camera is activated.

11. The method as claimed in claim 10, further comprising:

communicating with an external device,

wherein the third power range is a power range that the display apparatus consumes when the camera and the communicator are activated.

12. A display apparatus comprising:

a power measurer configured to detect power provided by a power supplier to components of the display apparatus; and

a power controller configured to determine whether the detected power is in a hacked power range between a first power range and a second power range, and when the detected power is in the hacked power range, control the power supplier to cut off the power to the components of the display apparatus.

13. The display apparatus of claim 12,

wherein the first power range is defined by a first lower boundary that is equal to no power consumption and a first upper boundary that is equal to power consumption when all components including the display are in a sleep mode,

wherein the second power range is defined by a second lower boundary equal to power consumption when the display is operating along with a main controller and a second upper boundary that is equal to all components operating including the display and main controller, and

14. The display apparatus of claims 13,

wherein the hacked power range is defined by the first upper boundary of the first power range, which equals the hacked lower boundary, and the second lower boundary of the second power range, which equals the hacked upper boundary.

15. The display apparatus of claim 12,

wherein the components of the display apparatus includes at least one of a display, a main controller, a communicator, a camera, a signal processor, a video processor, and an audio processor.
