Description

Enhanced super-stereoscopic display Cross Reference to Related Applications The application claims the benefit of U.S. provisional application No. 63/579,751, filed 8/30 of 2023, which is incorporated herein by reference in its entirety. Technical Field The present invention relates generally to the field of three-dimensional displays, and more particularly to new and useful systems and methods in the field of three-dimensional displays. Background The construction of multi-view 3D displays using a single screen comes mainly from two main directions, time multiplexing and spatial multiplexing. One way to understand this concept is that the frame rate, single view resolution (per-view resolution) and number of views of a 3D display in a given view cone share the same resource pool-the product of the frame rate and resolution of the underlying screen. The 3D display generated by the 3D display along the time multiplexing design direction has a refresh rate lower than that of the base screen, and the 3D display generated by the 3D display along the time multiplexing design direction has a single view resolution lower than that of the base screen. In the case of spatial multiplexing, when highly detailed images are desired, reduced single view resolution may adversely affect the viewing experience. For example, in 3D displays using spatial multiplexing techniques (examples include, but are not limited to, designs using lenticular lenses, parallax barriers (parallaxes) and lens arrays), text of relatively small word sizes may sometimes be unreadable due to the reduction in single view resolution. Thus, there is a need in the field of three-dimensional displays to create a new and useful three-dimensional display system and method. The present invention provides such new and useful three-dimensional display systems and methods. Brief Description of Drawings Fig. 1 is a schematic representation of an example of an apparatus.

Description of the preferred embodiments The following description of the preferred embodiments of the invention is not intended to limit the invention to those embodiments, but is intended to enable any person skilled in the art to make and use the invention. 1. Summary. For example, as shown in FIG. 4, the device 10 may include one or more of a screen 100, 100', an optical element 200, a parallax generator 300, an aliasing suppressor 400, a crosstalk suppressor 500, an optical volume 600, a volume guide 650, a computing system 700, and/or any component. The display is preferably used to present three-dimensional images (e.g. holographic images, light field images, etc.) and/or direction-dependent views (e.g. when different scenes are presented to different viewing directions with or without the aid of a tracking device) to one or more viewers. The display preferably works without using peripheral devices such as glasses (e.g., a three-dimensional image is perceived as three-dimensional for each viewer without using peripheral devices). However, additionally or alternatively, the display may be used with a peripheral device (e.g., to enhance tracking of the viewer, to enhance three-dimensional perception, to enable three-dimensional perception, to control the position of the viewer, etc.). The display may also be configured to display two-dimensional images (e.g., simultaneously, contemporaneously, concurrently, or separately with the three-dimensional images, as shown in fig. 1, 2, and/or 3). The device is preferably a display capable of concurrently presenting one or more 2D images and 3D images. However, in some variations, the device may be a transparent three-dimensional display (e.g., as shown in fig. 1
