Image display apparatus and operating method of the same
An operating method of an image display apparatus includes detecting a screen aspect ratio of an input image; determining rotation control information regarding a tiled display of the image display apparatus, the tiled display including a plurality of individually rotatable display modules, according to the detected screen aspect ratio of the input image; rotating each of the plurality of display modules according to the determined rotation control information; and controlling the plurality of display modules to display the input image according to the determined rotation control information.
1. An image display apparatus comprising:
a tiled display including a first display and a second display arranged side-by-side in a horizontal direction, each of the first display and the second display being rotatable; and
at least one processor configured to:
control the tiled display to display an image having a 16:9 screen aspect ratio,
obtain an input image having a 21:9 screen aspect ratio,
determine rotation control information comprising a rotating direction and a rotation angle of each of the first display and the second display to rotate the first display and the second display, according to the 21:9 screen aspect ratio of the input image, the rotating direction of the first display being identical to the rotating direction of the second display,
rotate each of the first display and the second display according to the determined rotation control information, and
control the tiled display including the rotated first display and the rotated second display to display the input image having the 21:9 screen aspect ratio,
wherein the rotation control information comprises information for moving each of the first display and the second display such that the first display and the second display form one surface without overlap.
2. The image display apparatus of claim 1 , wherein the at least one processor is further configured to control white balances of the first display and the second display that displayed the input image.
3. The image display apparatus of claim 1 , wherein the at least one processor is further configured to determine the rotation angle to be equal to 90 degrees.
4. The image display apparatus of claim 1 , wherein the at least one processor is further configured to determine the rotation angle of each of the first display and the second display at a certain time interval by using the determined rotation control information.
5. The image display apparatus of claim 1 , wherein the at least one processor is further configured to:
rotate each of the first display and the second display according to the determined rotation control information without vertically moving the center of each of the first display and the second display.
6. An operating method of an image display apparatus comprising a tiled display including a first display and a second display arranged side-by-side in a horizontal direction, each of the first display and the second display being rotatable and at least one processor to control the plurality of individually rotatable displays, the operating method comprising:
by the at least one processor:
controlling the tiled display to display an image having a 16:9 screen aspect ratio;
obtaining an input image having a 21:9 screen aspect ratio;
determining rotation control information comprising a rotating direction and a rotation angle of each of the first display and the second display for rotations of the first display and the second display included in the tiled display of the image display apparatus, according to the 21:9 screen aspect ratio of the input image, the rotating direction of the first display being identical to the rotating direction of the second display;
rotating the tiled display including the first display and the second display according to the determined rotation control information; and
controlling the tiled display including the rotated first display and the rotated second display to display the input image having the 21:9 screen aspect ratio,
wherein the rotation control information comprises information for moving each of the first display and the second display such that the first display and the second display form one surface without overlap.
7. The operating method of claim 6 , further comprising controlling, by the at least one processor, white balances of the first display and the second display that displayed the input image.
8. The operating method of claim 6 , wherein the determining of the rotation control information for the rotations of the first display and the second display included in the tiled display comprises determining the rotation angle to be equal to 90 degrees.
9. The operating method of claim 6 , further comprising:
determining, by the at least one processor, a rotation angle for the rotations of the first display and the second display included in the tiled display at a certain time interval by using the determined rotation control information.
10. The operating method of claim 6 , further comprising rotating each of the first display and the second display according to the determined rotation control information without vertically moving the center of each of the first display and the second display.
11. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein,
wherein the computer readable program, when executed on a computing device, causes the computing device to:
control a tiled display of an image display apparatus including a first display and a second display arranged side-by-side in a horizontal direction, each of the first display and the second display being rotatable, to display an image having a 16:9 screen aspect ratio;
obtain an input image having a 21:9 screen aspect ratio;
determine rotation control information comprising a rotating direction and a rotation angle of each of the first display and the second display for rotations of the first display and the second display, according to the 21:9 screen aspect ratio of the input image, the rotating direction of the first display being identical to the rotating direction of the second display;
rotate each of the first display and the second display according to the determined rotation control information; and
control the tiled display including the rotated first display and the rotated second display to display the input image having the 21:9 screen aspect ratio,
wherein the rotation control information comprises information for moving each of the first display and the second display such that the first display and the second display form one surface without overlap.
