Dual‐view integral imaging display based on point light sources

Abstract

We propose a dual‐view integral imaging display based on point light sources. The proposed dual‐view integral imaging display is composed of an organic light‐emitting diode and a liquid crystal panel. The point light sources are displayed on the organic light‐emitting diode. The elemental images 1 and 2, which are captured from three‐dimensional scenes 1 and 2, are alternatively aligned on the liquid crystal panel in the horizontal direction. Two adjacent elemental images 1 and 2 are coupled and corresponded to one point light source. The coupled elemental images 1 and 2 are illuminated by the corresponding point light source. It satisfies the practical applications that the viewing zones are respectively located at the left and right of the proposed dual‐view integral imaging display. A prototype of the proposed dual‐view integral imaging display is developed, and good verifying results are obtained.

High-Aperture-Ratio Dual-View Integral Imaging Display

“…In the conventional point light source ar horizontal and vertical widths are identical. Since the elemental Images 1 and 2 ternatively displayed in the horizontal direction, the light rays through the ele Images 1 and 2 are modulated into the left and right directions [24]. A gradient-width point light source array is proposed, as shown in Figure 3.…”

“…The pseudoscopic problem was also resolved by reversing the direction of display process. Therefore, the point light source array was introduced in the DVII display [24]. In the DVII display based on the point light source array, there are display and non-display zones in the reconstructed 3D image.…”

“…Figure 1. Structures of the conventional point light source array and the elemental image array.Because of the crosstalk of the adjacent point light sources, the light rays emitted from the left and right marginals of each point light source travel through the left and right marginals of the assigned elemental image, as shown in Figure2[24]. Since the light rays through the elemental images are parallel, the vertical viewing zones reconstructed by the elemental images partially overlap.…”

Dual‐view one‐dimensional integral imaging display using parallax barrier

“…The dual‐view one‐dimensional integral imaging display using the parallax barrier has less space and lower cost than that using the lenticular lens array. The viewing angle of the dual‐view one‐dimensional integral imaging display using the parallax barrier can be increased by decreasing the aperture width of the slit 16 . However, the optical efficiency of the dual‐view one‐dimensional integral imaging display using the parallax barrier is decreased along with the decrease of the aperture width of the slit.…”

“…The viewing angle of the dual-view one-dimensional integral imaging display using the parallax barrier can be increased by decreasing the aperture width of the slit. 16 However, the optical efficiency of the dual-view one-dimensional integral imaging display using the parallax barrier is decreased along with the decrease of the aperture width of the slit. Thus, the restriction between the viewing angle and the optical efficiency hinders the application of the dual-view one-dimensional integral imaging display using the parallax barrier.…”
