“…Figure shows that the rays from the three points would insect at a single point, and we will prove this in another section. The distance from point M to point P in x direction is defined as the width of viewing zone in x axis and marked as ΔX . Besides the main lobe, the edge points of side lobes would locate at the same distance to the barrier in z direction.…”

“…Instead of a single ray, angular luminance profile is obtained by using ray fans and to describe the luminance distribution at different angles. To find the luminance in the intersection area, we propose to evaluate the total luminance at a specific observation point as:

L_{italictotal} = {((), L_{4} \times L_{5} \times L_{6})}^{1 / 3},

where L 4 , L 5, and L 6 are luminance emitting from points 4, 5, and 6 and measured at a specific observation point, respectively.…”

“…Especially the verification studies on OVD and side lobes along OVD have rarely been done. The authors proposed a prior study to show how to find the designated eye position (DEP) and also the method to define the OVD without the refractive index consideration . In this paper, we study this issue from the optical design principle, and both geometric and ray tracing methods are applied to explain the relationship of the parameters.…”

The optimal viewing distance was proposed as a parameter for designing a parallax barrier 3D display. It can be designed based on simple geometric method and by considering the pitches of image display pixels and parallax barrier, or even including the aperture ratios of the image display pixels and parallax barrier. It can be analyzed by using ray tracing method. By considering the optical refraction index of the cover glass, the angular behavior of the system becomes more realistic; however, the geometric method is difficult to be used. We propose a revised method for estimating the view distance and angular behavior. In this paper, we have demonstrated a designated eye position (DEP) for each view and shown that multiple DEPs make a circular curve around the center of the display. We prove the new concept by comparing the optical ray tracing calculations and optical measurement.

Optimal Viewing Distance (OVD) is a basic and important auto‐stereoscopic 3D (AS3D) display characteristic. A number of studies, especially in the 3D display design and metrology fields, have mentioned this item for a long time. Unfortunately, there have been few theoretical and empirical studies on OVD. In this paper, we study OVD based on designer's formula, and geometrical and ray tracing approaches are applied to the simulation and measured data. We find that the OVD no more exist in practical cases, and we suggest the thought OVD should be modified by designated eye position (DEP).

Radius of curvature is an important factor for flexible displays, especially in 3D field; however little research has been done. This paper provides a design reference for flexible autostereoscopic (AS3D) displays with different radius of curvature based on a raytracing approach. The recommended design radius of curvature for 4-inch-wide (10-cm) two-view flexible AS3D is the value larger than 30 cm.Author Keywords 3D; autostereoscopic; flexible; viewing zone; and radius of curvature.
