Dual-view one-dimensional integral imaging display based on compound parallax barrier

The optimal viewing distance limits the movement range of the observers. We report a dual-view one-dimensional integral imaging display based on a compound parallax barrier. The elemental images I and II are displayed on the left and right of an organic light-emitting diode, respectively. The sub-polarizers I and II polarize the light rays emitted from the elemental images I and II, respectively. The compound parallax barrier consists of three kinds of parallax barriers. Two invariable parallax barriers are in the middle of the compound parallax barrier. The other parallax barriers are on the left and right of the compound parallax barrier and are denoted as variable parallax barriers I and II, respectively. The pitches of the variable parallax barriers I and II are variable. The invariable parallax barriers determine the widths of the primary viewing zones I and II. The observers with polarizer glasses I only watch three-dimensional (3D) image I, and those with polarizer glasses II only watch 3D image II. The optimal viewing distances I and II are easily adjusted by changing the pitches of the variable parallax barriers I and II, respectively.
