50.4: High Resolution Autostereoscopic 3D Display with Proximity Projector Array

Abstract

A 3D architecture which exploits proximity projector array to project tiled image of low magnification ratio from microdisplays has been proposed as a solution for large screen and high resolution spatial multiplex autostereoscopic display. with descent lenticular and projection optics design associated with dedicated pixel mask, the proposed 3D configuration shows low crosstalk between viewing zones and demonstrates a potential alternative to increase pixel count for wide view and high resolution 3D displays.

Three-dimensional lenticular display synthetic image rendering based on light field acquisition

“…Three-dimensional (3D) display technologies have been studied for decades with various ways to produce high-fidelity 3D scenes. 1 The lenticular 3D display technology, based on a sheet of cylindrical lenses (lenticulars) overlaid onto a LCD screen, is relatively simple to implement, and its quality of 3D image reconstruction appears adequate for numerous commercial 3D products and applications. 2 The key element of lenticular 3D display is to render an accurate synthetic image, which is mapped and synthesized from mulitiview images.…”

“…The inability to completely isolate left/right image channels for left/right eyes often results in crosstalkthe content from one channel is partly presented in another channel. 5 Two different approaches are commonly used to reduce the crosstalk effects 6,7 : (1) to incorporate extra elements, for example, parallax barriers, pixel masks, or add a timing control scheme; and (2) to correct subpixel values in the synthetic images to minimize the crosstalk. Examples include crosstalk coefficient calculation 8,9 or weighted value.…”

Polymeric-lens-embedded 2D/3D switchable display with dramatically reduced crosstalk

“…Many approaches have been proposed to reduce crosstalk. Some of them are based on image processing [17], while the mainstream approach is based on optimizing the optical system, such as a specifically designed pixel mask for projection display [18], combined lens structures [19,20], pixel optimization by modifying the layout of light blocking components [21], and using triplet structures for reducing crosstalk at large angles [22].…”

Optical simulation for cross‐talk evaluation and improvement of autostereoscopic 3‐D displays with a projector array

“…The concept is to tile many projection images with a low magnification ratio from the microdisplays to create a large-sized 2-D image source with a large pixel count and small pixel size, and exploit the lenticular lens located in front of the tiled projection image to split the pixels needed to generate the perspective view of a 3-D picture. 6,7 Some prototypes have been developed based on the proposed 3-D architecture by using a transmissive LCD, 8,9 but the resolution is difficult to increase and serious cross-talk has not yet been resolved. In this paper, optical simulation using a ray-tracing program has been used to illustrate the cross-talk issues from different mechanisms and corresponding solutions for the proposed 3-D architecture based on LCoS microdisplays.…”
