ABSTRACT:
A display has a display part displaying an image signal, an image signal processor providing the image signal to the display part, a pen sensor sensing at least two locations on a main body of the pen positioned on the display part and generating a first pen sensor signal and a second pen sensor signal, and a controller controlling the image signal processor to display the image as rotated based on the first pen sensor signal and the second pen sensor signal. The display senses an exact display direction which a user wants to use without operating a display direction converting switch and rotates the displayed image according to the sensed display direction.
