Abstract
A display including an optical element disposed on a pixel array of a display panel; an optimal viewing distance control device configured to adjust primary view images seen through both eyes of a viewer to a first view image and second view image based on a viewer's position information sensed by a sensor, to automatically adjust other view images between the primary view images to view images separated at regular intervals, and to produce a view map using the adjusted primary view images and the adjusted other view images between the primary view images; a 3D formatter configured to map pixel data of a multi-view image based on the view map received from the optimal viewing distance control device; and a display panel driving circuit configured to write the pixel data of the multi-view image received from the 3D formatter to the display panel.
