Abstract
A wide-angle autostereoscopic three-dimensional (3D) image display method is provided. The method includes tracking a user in an autostereoscopic 3D image viewing state with respect to a display panel including a plurality of display units, obtaining a first distance between the display panel and a spectroscopic unit array including a plurality of spectroscopic units and a first width associated with each spectroscopic unit, and determining a second distance between a viewing position of the user and the display panel. The method also includes determining a width of a display unit combination corresponding to the second distance. Further, the method includes calculating a gray value of each display unit based on the width of the display unit combination and a reference value of the distance between each display unit and an edge of the display unit combination and displaying the 3D image on the display panel.
