ABSTRACT:
A display system displaying an image on a basis of an image signal received from an image signal source, including: a key signal generator generating a key signal according to a user's manipulation; a configuration controller providing a GUI for controlling a display state of the image, and outputting a control order corresponding to the user's manipulation on the GUI, and detecting whether a user's access to the GUI is limited; and a display controller controlling the display state of the image on a basis of the control order received from the configuration controller, recognizing the key signal as a first control signal to implement a pre-set control function according to the recognized first control signal if the key signal is input from a key signal input part while determining that the user's access to the GUI is not limited, and recognizing the key signal as a second control signal to control the display state of the image according to the recognized second control signal if the key signal is input from the key signal input part while determining that the user's access to the GUI is limited.
