Abstract:
1. A dual layer parallax barrier-based 3D display device, the 3D display device comprising: an image panel configured to display a left image and a right image so as to alternately display a left-image column and a right-image column; a dual layer parallax barrier configured to block specific portions of the displayed images, the dual layer parallax barrier including a first common electrode, a second common electrode, a plurality of first individual electrodes, a plurality of second individual electrodes, and a liquid crystal layer; the dual layer parallax barrier configured to operate as Normally White in which the liquid crystal layer blocks light when a voltage is applied to the electrodes; a driving unit configured to drive the electrodes based on a distance between the image panel and a viewer so as to allow the viewer to view the left image and the right image, separately; wherein the driving unit, in a particular state, is configured to drive the electrodes in one of the following configurations:
