Electronic apparatus and method of driving the same

An electronic apparatus comprising:

• a display part including a first display area and a second display area opposite to the first display area;
• a touch screen configured to sense a first touch input from the first display area and a second touch input from the second display area;
• and
• a display controller configured to control activation and deactivation of the first display area and the second display area based on the first touch input and the second touch input,
• wherein the display controller is configured to set the first display area as a main display area displaying a main image and set the second display area as a sub display area displaying a sub image when a first touch area of the first touch input is less than a second touch area of the second touch input or when a first number of touches of the first touch input is less than a second number of touches of the second touch input.

A method of driving an electronic apparatus comprising a display apparatus including a first display area and a second display area opposite to the first display area, the method comprising:

• receiving at least one of a first touch input from the first display area and a second touch input from the second display area;
• determining a driving mode based on the first touch input and the second touch input;
• and
• controlling activation so as to display an image and deactivation so as not to display an image of the first display area and the second display area according to the driving mode,
• wherein the determining the driving mode comprises:
• determining a first touch area of the first touch input;
• determining a second touch area of the second touch input;
• and
• determining one of a first driving mode, a second driving mode, and a third driving mode as the driving mode based on the first touch area and the second touch area, the first driving mode activating the first display area and deactivating the second display area, the second driving mode activating the first display area and activating the second display area, and the third driving mode deactivating the first display area and activating the second display area, wherein the first display area is deactivated when the first touch area of the first touch input is larger than a first threshold area relative to an entire area of the first display area.
