Abstract

A display apparatus is provided. The display apparatus includes a sensor configured to sense ambient light, a display configured to provide a screen including a first area which displays content and a second area outside the first area and a processor configured to change a size of the second area based on the sensed ambient light.

First claim

What is claimed is:

1. A display apparatus, comprising:
at least one sensor;
a display; and
a processor configured to control the display apparatus,
wherein the processor is configured to control the display to:
identify whether to operate in a first mode or a second mode based on a user being detected via the sensor;
display a content on an entire area of the display when the first mode is identified; and
provide a shadow effect to a partial area of a second area located on a perimeter of a first area while the content is displayed on the first area of the display when the second mode is identified, the shadow effect being identified based on at least one of an intensity or a direction of light sensed via the sensor.

2. The display apparatus as claimed in claim 1 , wherein the processor is configured to identify an opposite side to an incident direction of the sensed light from among the second area as the partial area.

3. The display apparatus as claimed in claim 1 , wherein the processor is configured to control a size of the partial area proportional to the intensity of the sensed light from among the second area.

4. The display apparatus as claimed in claim 1 , wherein the processor is configured to:
divide the partial area into a plurality of areas; and
control the display to differently display at least one of a color, chroma and brightness of each of the plurality of areas.

5. The display apparatus as claimed in claim 1 , wherein the processor is configured to apply a gradation technique to the partial area.

6. The display apparatus as claimed in claim 1 , wherein the processor is configured to:
divide the second area into a plurality of areas;
reduce a size of at least one area located in an incident direction of the sensed light from among the plurality of areas;
enlarge a size of at least one area located on an opposite side of the incident direction of the sensed light; and
provide the shadow effect to at least one area located in an opposite direction to the incident direction of the sensed light.

7. The display apparatus as claimed in claim 1 , wherein the processor is configured to provide the shadow effect for the first area and the partial area of the second area.

8. The display apparatus as claimed in claim 1 , wherein the processor is configured to provide the shadow effect for a bezel of the display apparatus to the partial area of the second area.

9. The display apparatus as claimed in claim 1 , wherein the processor is configured to, based on the intensity of the sensed light, change a brightness of the first area and the second area and provide the shadow effect.

10. The display apparatus as claimed in claim 1 , wherein the sensor comprises a first sensor configured to sense the at least one of the intensity and the direction of light and a second sensor configured to detect the user, and
wherein the processor is configured to identify the second mode based on the user not being sensed through the second sensor for a predetermined time.

11. The display apparatus as claimed in claim 10 , wherein the processor is configured to control the display to:
display a first content on the entire area of the display; and
display a second content different from the first content on the first area.

12. A method for controlling a display apparatus, the method comprising:
detecting a user;
identifying whether to operate the display apparatus in a first mode or a second mode based on the user being detected;
displaying, based on the first mode being identified, a content on an entire area of the display apparatus;
sensing a peripheral light of the display apparatus; and
displaying, based on the second mode being identified, the content on a first area of the display apparatus and a shadow effect on a partial area of a second area on a periphery of the first area based on at least one of an intensity or a direction of the peripheral light.

13. The method as claimed in claim 12 , wherein the displaying comprises identifying an opposite side to an incident direction of the sensed light from among the second area as the partial area.

14. The method as claimed in claim 12 , wherein the displaying comprises controlling a size of the partial area proportional to the intensity of the sensed light from among the second area.

15. The method as claimed in claim 12 , wherein the displaying, based on the second mode being identified, comprises:
dividing the second area into a plurality of areas;
reducing a size of at least one area located in an incident direction of the sensed light;
enlarging a size of at least one area located in an opposite side of the incident direction of the sensed light; and
providing the shadow effect to at least one area located in an opposite direction to the incident direction of the sensed light.

16. The method as claimed in claim 12 , wherein the displaying comprises providing the shadow effect for the first area to the partial area of the second area.

17. The method as claimed in claim 12 , wherein the displaying comprises providing the shadow effect for a bezel of the display apparatus to the partial area of the second area.

18. The method as claimed in claim 12 ,
wherein the second mode is identified based on the user not being sensed for a predetermined time.

19. The method as claimed in claim 18 , wherein the displaying the first area and the second area comprises controlling the display to display a first content on the entire area and display a second content different from the first content on the first area.

20. A non-transitory computer readable recording medium comprising a program to execute a method for controlling a display apparatus, wherein the method comprises:
obtaining a first sensing value indicating a user from a first sensor;
identifying whether to operate the display apparatus in a first mode or a second mode based on the first sensing value;
displaying, based on the first mode being identified, a content on an entire area of the display apparatus;
obtaining a second sensing value of a peripheral light of the display apparatus from a second sensor;
displaying, based on the second mode being identified, the content on a first area of the display apparatus and a shadow effect on a partial area of a second area on a periphery of the first area based on at least one of an intensity or a direction of the peripheral light.
