Display device and control method thereof

A display device comprising:

• a scent emission unit configured to emit scents;
• a sensor unit configured to sense input to the display device;
• a display unit configured to display content including plural pages;
• and
• a processor configured to control the scent emission unit, the sensor unit and the display unit,
• wherein the processor is further configured to:
• detect page transition input from a first page to a second page while the first page included in the content is being displayed on the display unit;
• switch the first page to the second page in response to the detected page transition input and detect a page transition speed from the first page to the second page;
• and
• emit a scent corresponding to the switched second page based on the detected page transition speed:
• wherein the processor emits the scent at a first emission speed when the detected page transition speed exceeds a threshold speed,
• wherein the processor emits the scent at a second emission speed when the detected page transition speed is equal to or less than the threshold speeds, and
• wherein the first emission speed is faster than the second emission speed.
