US 2014/0192172 A1 · 3D DISPLAY DEVICE USING BARRIER AND DRIVING METHOD THEREOF

Abstract

A 3D display apparatus is provided, which includes a display panel which displays a multi-viewpoint image, a barrier arranged on one side of the display panel unit, and a controller which controls the barrier to alternately form light transmitting areas and light blocking areas. The barrier includes a liquid crystal layer, a plurality of upper electrodes arranged to be spaced apart from one another on an upper surface of the liquid crystal layer, and a plurality of lower electrodes arranged to be spaced apart from one another on a lower surface of the liquid crystal layer.
