Display device generating tactile feedback and method of controlling the same

A display device comprising:

• a display unit configured to display a digital image;
• a sensor unit configured to sense a control input;
• a tactile feedback unit configured to generate a tactile feedback;
• and
• a controller configured to control the display unit, the sensor unit, and the tactile feedback unit,
• wherein the controller is further configured to:
• detect a first control input to rotate the digital image,
• generate a first tactile feedback in a first part of a touch region of the first control input and a second tactile feedback in a second part of the touch region when rotation of the digital image begins,
• change at least one of the first tactile feedback and the second tactile feedback according to a first rate if a rotation angle of the digital image is a first angle, and
• change at least one of the first tactile feedback and the second tactile feedback according to a second rate if the rotation angle of the digital image is a second angle,
• wherein each of the first rate and the second rate is a rate of the second tactile feedback in relation to the first tactile feedback, and the second rate is greater than the first rate.
