Disclosed is a method of controlling a display device including displaying a digital image, detecting a first control input to rotate the digital image, generating a first tactile feedback in a first part of a touch region and a second tactile feedback in a second part of the touch region when rotation of the digital image begins, changing at least one of the first and second tactile feedbacks according to a first rate if a rotation angle of the digital image is a first angle, and changing at least one of the first and second tactile feedbacks according to a second rate if the rotation angle of the digital image is a second angle. 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.
