Claim:
A display apparatus comprising: an organic light emitting panel which alternately scans a left-eye image and a right-eye image in units of a frame; a signal transmitter which outputs a control signal to external shutter glasses to open or to close a left-eye shutter and a right-eye shutter of the external shutter glasses; and a controller which controls the signal transmitter to make open and closed states of the left-eye shutter and the right-eye shutter to be opposite to each other, and controls emission of the organic light emitting panel to display an image corresponding to an open shutter and not to display an image opposite to the open shutter when one of the left-eye shutter and the right-eye shutter is open, wherein the controller controls the organic light emitting panel to be in a non-emission state while the left-eye image or the right-eye image is being scanned to the organic light emitting panel, and be in an emission state while the left-eye image or the right-eye image is maintained after being completely scanned.
