1. A display device for displaying a pixel-based graphical content, comprising:
a first display screen which faces in a first direction;
a first pixel matrix configured to emit light through the first display screen;
a second display screen which faces in a second direction, different from the first direction;
a second pixel matrix configured to emit light through the second display screen;
a light-tight material disposed between the first pixel matrix and the second pixel matrix so that the first pixel matrix and the second pixel matrix are independently operable; and
a controller configured to:
control the first pixel matrix to emit light which passes through the first display screen and passes into surroundings of the display device in the first direction so that graphical content is displayed on the first display screen, based on image data that define the graphical content,
control the second pixel matrix to emit light which passes through the second display screen and passes into surroundings of the display device in the second direction so that graphical content is displayed on the second display screen, based on image data that define the graphical content, and
operate in a plurality of display modes including:
a first display mode in which the graphical content as defined by the image data is only displayed on one of the first display screen and the second display screen and the other one of the first display screen and the second display screen is deactivated, and
a second display mode in which identical graphical content is displayed on both the first display screen and the second display screen.
