“…The ray tracing simulation is presented to calculate the changes of the number of the intended subpixels with the angular, the axial, and the lateral misalignment. A 3-view slanted parallax barrier with a pentile display system is assumed, which was implemented in our previous work [10]. This system verifies that our analysis is valid not only for an RGB stripe structure but also for a pentile structure, and the simulation results can be verified with the implemented system easily.…”

“…It separates the view images spatially with the optical devices and provides binocular disparities to observers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. A multi-view display system is usually implemented with 2D display systems such as flat panel displays or projectors, and takes advantages of their high lateral resolution [1][2][3][4].…”

“…In recent high-resolution multi-view displays, the pitch of the optical structure is similar to the pixel pitch [9,10]. Furthermore in slanted lenticular display, the alignment of slant angle is crucial, otherwise the views are scrambled [8][9][10]. To build a personal multi-view display with the individual display panel, it is essential to have a standard calibration method [9].…”

We propose a novel calibration method which can be applied to all kinds of panel-type multi-view displays. We analyze how the angular, the axial, and the lateral misalignment affects the 3D image quality in a panel-type multi-view display. We demonstrate the ray optics simulation with a 3-view slanted parallax barrier system using pentile display for the quantitative calculation. Based on the analysis, we propose a new alignment pattern for all kinds of panel-type multi-view displays. The proposed pattern is sensitive to all of the angular, the axial, and the lateral misalignments. The high spatial frequency images and on and off alignment in the proposed pattern help observers to calibrate the system easily. We theoretically show the generality of the proposed alignment pattern and verify the pattern with image simulations and experiments.

Distributed real‐time rendering for ultrahigh‐resolution multiscreen 3D display

Large‐scale autostereoscopic three‐dimensional (3D) displays can give audiences a truly immersive feeling with strong visual impact. However, the traditional autostereoscopic 3D display systems are limited by the display hardware, making it difficult to directly achieve large‐scale 3D displays with high resolution. Multiscreen splicing with laser backlights can be used for large‐scale and ultrahigh‐resolution 3D display, but it normally results in subscreen image asynchronization, view zone error, or obvious edge overlapping. To solve the problems mentioned above, a distributed real‐time rendering system for ultrahigh‐resolution multiscreen 3D display is proposed. Fifteen 3D LCD display devices are driven through a host, cooperating with laser backlights, a lenticular lens array (LLA), and a directional diffuser to display high resolution, high frame rate, large size, and wide‐viewing angle 3D images. The resolution of the whole display system can reach 23,040 × 21,600. The rendering system provides a large‐scale and real‐time 3D scene image with an ultrahigh‐definition resolution at a speed of 40 frames per second and high quality.

This research aims at designing and realizing a 3D display system which allows the viewers to see 3D images in both landscape and portrait modes of the display. In this paper, we define 3D characteristics for landscape and portrait modes using the lens pitch and slanted angle. And we find adequate design parameters for the 3D display compatible to both the landscape mode and the portrait modes. Finally, we consider moiré effect and find the condition where no more artifact happens by simulation of convolution of the panel and the optical components in the frequency domain. In this research, we made the actual 3D display system through the light field 3D Reconstruction method where 3D images clearly observable in both landscape and portrait modes.
