Abstract: Provided is a method of forming a dynamic maximal viewing zone (DMVZ) of an autostereoscopic display apparatus. The method includes rearranging viewpoint images for each three dimensional (3D) unit pixels of a certain period k when a viewer deviates in a depth direction from a designed viewing distance (DVD), wherein the certain period k is determined according to a distance by which the viewer deviates in the depth direction from the DVD.

Abstract: Provided is an autostereoscopic three-dimensional image display apparatus. The autostereoscopic three-dimensional image display apparatus includes a display panel including an array of a plurality of sub-pixels, and an optical plate or a line light source, which is spaced a predetermined interval from the display panel at a predetermined inclination angle, wherein an inclination angle of the optical plate or the line light source with respect to a vertical direction of the display panel is determined by an equation.
