DETAILED DESCRIPTION OF THE INVENTIONDescribed herein is a multiplexed multiple-view, autostereoscopic, and high-angular resolution, light field display. The light field display is viewable with both horizontal and vertical parallax. Light field display multiplexing is a method of increasing the density of views (pixels) by shifting the light path or light field in or from the projector. Multiplexing in general is a method of sending more than one signal over a link at a time. Specifically, for a light field display, multiplexing is sending multiple images in the time frame that a single frame would be sent in a non-multiplexed display, corresponding to some change in the optical system of the display for each multiplexed frame. A multiplexed image comprises two or more light field images, with each light field image projected

Of the direct projection light field display is a light field, which is a 3D representation of a continuously distributed light field based upon a finite number of views with angular resolution exceeding that of the human eye. A multiplexed light field display is achieved by multiplexing or overlaying two or more images, either temporally or spatially. A spatially multiplexed display may be described as one which uses lenses, motors, or other equivalent optical or mechanical components in combination with the light source to display separate views at different viewing angles. A spatially multiplexed light field display can produce unique images for multiple viewer or observer locations. By using the same hardware to create two or more images that are projected at different positions or angles and changing the image position at a rate faster than can be discerned by a viewer, the number of pixels in the light field display can be effectively multiplied by the number of projector image positions achievable by the multiplexing system. The minimum frame rate for a display is between 24-30 Hz, based on the minimum rate that a human eye cannot discern, which is less than about 30 Hz. Therefore, for a multiplexed system, the frame rate must increase by the same factor that the number of multiplexed frames per frames increases. In one example, if a normal display refreshes at 30 Hz, an multiplexed image with four output light field images each at a different location requires an overall frame refresh rate of 120 Hz so that each of the four output light fields has a refresh rate of at least 30 Hz. Rapidly changing the projection image position of each of the projectors in a light field projector device using a multiplexing component can thus provide a significant increase in pixel

94 are also illustrated in FIG. 20A. An alternative embodiment of the present disclosure describes a flat panel based multiplexed display. The flat panel-based display may include, but is not limited to, liquid-crystal display (LCD) or light emitting diode (LED) technologies, or a combination of both as a multiplexed, autostereoscopic, and high-angular resolution, light field display. The light field display is viewable with both horizontal and vertical parallax where the multiplexing is used to increase the effective resolution in one-dimension or two dimensions, increasing the display quality. Projector array-based displays can be difficult to design, at least due to the required inclusion of many densely-oriented projectors with precise alignment. Referring to FIG. 21, a light field display includes an enclosure 104 that houses a projector array 50 and two lens systems: a collimating optical system 18 or diffusing optical system and a display optical system 22. The projector array 50 includes multiple projectors, each of which produces light. The projectors in the projector array may be pico-projectors, specialized for augmented reality headsets or automotive heads-up displays (HUDs). The projectors receive image data and convert the image data into projected light. Projected light is then transmitted from the projectors to a collimating optical system 18 comprising a lens system or array. The light is then transferred from the collimating optical system 18 to a display optical system 22 which forms a multiplexed light field image. All optomechanical components fit within the lens enclosure 108. Generally, very high-brightness projectors are required for light field displays known in the art. An advantage of the light field displays of the present disclosure is the reduced brightness requirement for the projectors in the projector array 50. The decreased brightness requirement is achieved through the design of the direct projection display lens systems' ability to control.

10 Pages Posted: 9 Dec 2022 Abstract Three-dimensional (3D) display is the future technology of display. The insufficient refreshable information provided by the screen is one of the major bottlenecks that hinders the development of light field 3D display. In this paper, a time-multiplexed vector light field display is proposed to increase the amount of information by exploiting the time redundancy. A view modulator with fully coverage of metagrating matrix is adopted to generate two groups of time-sequentially lit-up intertwined views. With a small angular deflection requirement, the time-multiplexed strategy based on intertwined views are beneficial because the complexity of directional backlights is reduced. Moreover, the intertwined views involve minimum stray light and crosstalk, compared with successively arranged views. Furthermore, a time-multiplexed vector light field 3D display is demonstrated with 18 views. The horizontal field of view reaches 51°. The potential applications include human-computer interaction, commercial exhibition, and medical hygiene.

Ball game score. However, what we see is not always what is really happening. In fact for most displays, the individual display segments are cycled through so that only one display is on at any given time. The cycle speed is so fast that the human eye perceives that all segments are on. brgprecision.com electronic-scoreboard.com nu-mediadisplays.com/signs/time-displays.php This slide provides examples of various electronics signs and explains that display segments are not all on simultaneously. digicam-tech.com 12 Project Lead The Way, Inc.

In this circuit all displays are continuously illuminated, each displaying one letter in the word. Though this method works, it is a VERY inefficient use of p ower. To illuminate the simpl e message CIAO in this way, 18 segments must be continu ously on. Can you think of another way to display this message that would use less power? This slide shows how a simple message can be displayed using seven-segments displays. The drawback to this method is that all displays are on simultaneously. To display CIAO, 18 segments must be on, all drawing current and using power. Ask students to consider ways that they could display the message WITHOUT running all displays simultaneously. 13 13 Project Lead The Way, Inc.

The pixel forming device 76 can be, for example, a Liquid Crystal on Silicon (LCOS) panel, a digital micromirror device (DMD), or other display device. The ray path then proceeds back through the folded prism 74 to a second bi-convex lens 72b and through to a series of projection doublets 78a and 78b. The ray path then continues to the LFP lens 98. The ray path continues to the multiplexing layer then to the display optical system 22. The multiplexed light field output 112 projected from the display optical system 22 comprises two individual light field images, shown as a first set of solid-line rays and a second set of dashed-line rays, which together make up the multiplexed light field output 112. It should be noted that in this configuration, the display optical system 22 may be any suitable display optical component including, but not limited to, a single lens, a lens array, a pinhole array, a metasurface, or a metalens. Multiplexing may be achieved using one or more multiplexing devices as described in other embodiments, but additionally in this configuration multiplexing may be achieved by changing the index of refraction of the additional multiplexing layer 118. This is achieved as the multiplexing layer 118, capable of the Kerr effect, is a component made of a material in which the refractive index of the material can be adjusted in response to an applied electric field. Various materials are known that are capable of the quadratic electro-optic effect and use of an optical component of one of these materials in combination with a device capable of creating the electric field required to adjust the material refractive index can achieve the same or similar multiplexed image. This can be achieved in one dimension and/or two dimensions. FIG. 3A illustrates an embodiment of
