## Abstract

A display apparatus includes a display panel which includes a plurality of sub pixels each outputting a sub pixel value of R, G, or B, a renderer which renders a multi-view image to be outputted by the display, and a controller which determines a rendering pitch according to a viewing distance of a user, and controls the renderer so that each of at least some of the plurality of sub pixels outputs a combined sub pixel value corresponding to a combination of sub pixel values corresponding to each of the plurality of views of the multi-view image according to the determined rendering pitch.
