9. A method for controlling an image display device, the method comprising:
performing wireless communication with a mobile terminal;
transmitting information for a screen posture direction of the image display device to the mobile terminal through the wireless communication;
receiving first screen information through the wireless communication from the mobile terminal when the screen posture direction of the image display device is different from a screen posture direction of the mobile terminal;
receiving second screen information through the wireless communication from the mobile terminal when the screen posture direction of the image display device is same as the screen posture direction of the mobile terminal, wherein the first screen information is different from the second screen information; and
displaying a mirroring image related to a current image captured by the mobile terminal based on the first or second screen information.
10. The method of claim 9 , further comprising:
measuring, by the image display device, the screen posture direction of the image display device using at least one sensor.
11. The method of claim 9 , wherein the second screen information is also transmitted from the mobile terminal to the image display device through the wireless communication when a screen of the mobile terminal and a screen of the image display device are located in a same direction.
12. The method of claim 9 , wherein the first screen information includes the current image captured by the mobile terminal and margin information while the second screen information includes the current image captured by the mobile terminal without the margin information.
13. The method of claim 12 , wherein the displaying the mirroring image further comprises:
displaying the mirroring image with a black margin when the screen posture direction of the image display device is different from the screen posture direction of the mobile terminal; and
displaying the mirroring image without the black margin when the screen posture direction of the image display device is same as the screen posture direction of the mobile terminal.
14. The method of claim 12 , wherein the margin information corresponds to right and left margins when the mobile terminal is in a portrait mode and the image display device is in a landscape mode, further the margin information corresponds to upper and lower margins when the mobile terminal is in the landscape mode and the image display device is in the portrait mode.
15. The method of claim 9 , wherein the wireless communication is based on Bluetooth, ZigBee or Wi-Fi.
16. The method of claim 9 , wherein the screen posture direction of the image display device or the mobile terminal corresponds to a landscape mode or a portrait mode.
17. An image display device, comprising:
a display module;
a wireless interface configured to perform wireless communication with a mobile terminal; and
a controller configured to control the wireless interface to:
transmit information for a screen posture direction of the image display device to the mobile terminal through the wireless communication,
