A display apparatus includes: a display; a motor configured to rotate the display; a sensor configured to sense rotation of the display; and a processor configured to output a driving signal for rotating the display in a first direction to the motor when an event for rotating the display from a first posture to a second posture occurs and output a driving signal for rotating the display in a second direction to the motor when it is identified that the display collides with an object on the basis of the driving signal output to the motor and a signal received from the sensor while the display rotates.
