Dual-view integral imaging 3D display by using orthogonal polarizer array and polarization switcher

Abstract

In this paper, a dual-view integral imaging three-dimensional (3D) display consisting of a display panel, two orthogonal polarizer arrays, a polarization switcher, and a micro-lens array is proposed. Two elemental image arrays for two different 3D images are presented by the display panel alternately, and the polarization switcher controls the polarization direction of the light rays synchronously. The two elemental image arrays are modulated by their corresponding and neighboring micro-lenses of the micro-lens array, and reconstruct two different 3D images in viewing zones 1 and 2, respectively. A prototype of the dual-view II 3D display is developed, and it has good performances.

Crosstalk‐free dual‐view integral imaging display

“…The dual‐view integral imaging (DVII) display presents two different 3D images in the left and right viewing directions, respectively. A time‐multiplexed DVII display is also proposed to improve the viewing angle . The polarized glasses are introduced to present two different 3D images in the viewing zone .…”

“…A timemultiplexed DVII display is also proposed to improve the viewing angle. 18 The polarized glasses are introduced to present two different 3D images in the viewing zone. 19 However, there are flipping images in the mentioned above DVII displays, limiting their applications.…”

14.3: See‐through 2D/3D Compatible Display Based on Integral Imaging

“…Integral imaging firstly proposed in 1908 by G. Lippmann [1] is considered to be one of the most promising 3D displays. It has the advantages of continuous viewpoint, full parallax, no requirement for special wearable equipment [2][3][4]. However, integral imaging still has some issues that need addressing, such as 2D/3D compatible display, see-through display of 3D images, etc.…”

35‐2: 3D/2D Switchable Display System Based on Integral Imaging

“…3D display includes holography display, integral imaging display, and volumetric display and so on. Integral imaging has the advantages of continuous viewpoint, full parallax, no visual fatigue, and free for glasses [1][2][3][4]. Therefore, integral imaging is considered to be one of the most promising 3D display technologies.…”
