We describe the design and performance of a multi‐view 3D display system displaying an adjustable number of views. This uses an 8K panel and a simple eye tracking method to extend the viewing zones over a very large range and provides a multi‐view 3D display with high resolution and smooth motion parallax that gives the viewer good freedom of movement. The results are obtained from a system built around a 32" 8k monitor with a 45 lpi lenticular screen; it gives good image depth with motion parallax to a single user, with a viewing angle more than 60.

Binocular 3D display systems, including virtual, augmented and mixed reality (collectively referred to as XR) devices support stereoscopic depth perception by presenting dichoptic views separately to the two eyes rendered according to their vantage points. A common human factors issue is a mismatch between the observer's physical interpupillary distance (IPD) and 1) the separation between the device optics and 2) the rendered/captured content. This paper provides a theoretical review of the importance and consequences for user experience of accurately estimating IPD and incorporating it into HMD adjustments, calibration and rendering.

THREE-dimensional display systems ,LED displays ,VALVES - Abstract
In a 3D display system, the displayed image is constantly switching between the left eye image and the right eye image. After the human eyes synthesize the two images, a 3D effect is formed. In the process of switching, the discontinuity of the image may cause display crosstalk to the human eyes. Therefore, the backlight is usually turned off during this process, which also leads to a decrease in display brightness. In the 3D display system described in this article, within the blacklight, all the front and rear phases of all the channels can be adjusted independently along with the synchronization signal, so to improve the backlight brightness while keep the low crosstalk, and the voltage and phase of the light valve can be adjusted for a better 3D display.

The intense visual impact brought about by glasses‐free 3D display has changed people's perception of traditional display, garnering increasing attention and research, and it is anticipated to reach a market size of billions of dollars within the next five years. However, a challenge lies in the scarcity of display content resources and their high degree of manual customization, leading to elevated costs for three‐dimensional (3D) display deployment, hindering widespread adoption. We propose a novel approach that combines a three‐dimensional reconstruction technique, specifically Neural Radiance Fields (NeRF), with multi‐viewpoint synthesis. Meanwhile, we integrate the Signed Distance Function (SDF) into the volume rendering framework of the reconstruction algorithm for representation fusion optimization. Finally, we utilize lenticular lens arrays to realize the 3D display effect. Experimental results show that our method achieves superior high‐quality reconstruction compared to previous algorithms and provides efficient display of custom‐captured scenes.

We propose a process to compose stereoscopic images based on measured values in an automotive 3D Head‐Up‐Display (3D HUD) equipped with parallax barrier and eye‐tracking camera. The information required for compositing is measured using an RGB camera and linked to the camera (eye) position coordinates. And the measurement is performed at dozens of camera locations. Then by approximating the information with a polynomial with the camera position and LCD pixel coordinates as a variable, the information required for image composition is generated at any camera (eye) position. This calibrates the effects of variations and distortions in the mounting of windshields and eye tracking cameras, and realizes optimal low crosstalk 3D image rendering for any eye position in real time.

The development of two‐dimensional (2D)/three‐dimensional (3D) switchable displays in the display market is limited due to the narrow depth of 3D display mode. In this paper, we propose a depth‐enhanced 2D/3D switchable display based on integral imaging that stacks multiple polarization switching layers and multiple polarization‐dependent liquid crystal micro‐lens arrays (LCMLAs) together. According to the change of the incident polarization state by the polarization switching layer, the polarization‐dependent LCMLA can realize the focusing effect and transmission effect respectively. Because different layers of polarization‐dependent LCMLA have different gaps (g) and the combination of different layers of polarization‐dependent LCMLA obtains different focal lengths (f), hence, multiple central depth planes can be generated to improve the depth of field (DOF) of the 3D mode. The 2D display mode is realized when all the layers of the polarization‐dependent LCMLA are in transmission effect. We experimentally developed a prototype of the proposed 2D/3D switchable display with two polarization switching layers and two polarization‐dependent LCMLAs. The results show that the DOF of the prototype is easily increased by more than two times. At the same time, the 2D image is also clearly presented in 2D mode without any distortion.

A method for estimating the proper slanted angle of an autostereoscopic lenticular lens sheet is proposed in this paper. A three‐dimensional(3D) display with the proper slanted lenticular lens sheet has the lower three‐dimension al(3D) crosstalk and less moiré pattern. To get the proper angle, a mathematical model describing the optical performance of the lenticular lens is established on the Snell's law and the ray tracing method. In this model, the shapes and the distribution of the display's subpixels are introduced as an important element to affect the slanted angle. A15.6" 3D display designed by this method is reported with a lower crosstalk and better 3D performance. [ABSTRACT FROM AUTHOR]

Binocular tone mapping is aiming at improving the overall image quality utilizing three‐dimensional display system based on the vision fusion ability. As the subjective perception is more convincible, a serial perception experiments are designed to investigate the overall image quality and visual comfort of the binocular tone mapping. It is found that the nonlinear combination of image quality contribution information exists, and the eye dominance has no significant effect on the results. Human vision is sensitive to the binocular disparity when utilizing the binocular tone mapping, and the binocular disparity limitation can be derived based on the visual comfort perception experiment.

Background Tabletop 3D display is one of the most challenging and exciting 3D displays. Among different 3D display technologies, the integral photography (IP) based tabletop 3D display is a promising 3D display with full‐color and real‐time rendering. Still, few can offer the in‐situ interaction in multi‐user scenes. Methods In this study, we proposed a novel tabletop 3D floating autostereoscopic display system with 360‐degree continuous visualization according to the optical path and rotation design. As the brightness of the floating image will be changed due to the different angles between light source and AIP, we analyzed the AIP‐based light reflectivity and derived the relation formulas of the reflectivity. We also proposed a depth‐based multiple viewpoint rendering algorithm for real‐time face and gesture tracking to achieve the vertical parallax supplement and model control. Results We verified the continuous visualization and light reflectivity analysis results via simulation experiments. As a result, the brightest setting angle (the angle corresponding to the highest light reflectivity) of AIP was influenced by the AIP reflection unit parameters. The proposed tabletop display realized the aerial display of the 3D model and could provide a continuous 360‐degree observation point of view between different polyhedron faces. Conclusions We proposed a tabletop autostereoscopic 3D display system and analyzed the AIP‐based light reflectivity. The light reflectivity formulas were worthy of reference for designing the AIP 3D or 2D displays. The proposed system could meet the observation of multiple users and offer in‐air interactions.

A resolution‐improved integral imaging (InIm) 3D display system is proposed. The proposed system consists of a 2D display panel, a lens array, and a polymer‐dispersed liquid crystal (PDLC). When the PDLC voltage changes, the PDLC has the different scattering display modes. Correspondingly, the scattering angle of the PDLC also changes, the light rays pass through the lens array at the appropriate angle to eliminate the gaps between the 3D pixels, so the proposed 3D display system can improve the resolution of 3D images. Compared with the conventional InIm 3D display system based on the holographic diffuser, the experimental results demonstrate the validity of our proposed 3D display system. [ABSTRACT FROM AUTHOR]

Sensor potentially allows and distinguish conductive and non‐conductive touch which gives advantage for thick gloves touch input and reduces typo errors for pressure input. As a result, this technology is promising for good performance on‐screen keyboard application. As the fabrication process is suitable to flexible substrate, application in flexible and foldable display is anticipated. [ABSTRACT FROM AUTHOR]

COMPUTER vision ,THREE-dimensional display systems ,ARTIFICIAL neural networks - Abstract
Recent advances in the field of computer vision can be attributed to the emergence of deep learning techniques, in particular convolutional neural networks. Neural networks, partially inspired by the brain’s visual cortex, enable a computer to “learn” the most important features of the images it is shown in relation to a specific, specified task. Given sufficient data and time, (deep) convolutional neural networks offer more easily designed, more generalizable, and significantly more accurate end‐to‐end systems than is possible with previously employed computer vision techniques. This review paper seeks to provide an overview of deep learning in the field of computer vision with an emphasis on recent progress in tasks involving 3D visual data. Through a backdrop of the mammalian visual processing system, we also hope to provide inspiration for future advances in automated visual processing. [ABSTRACT FROM AUTHOR]

THREE-dimensional imaging ,LIQUID crystal displays ,THREE-dimensional display systems - Abstract
Stereoscopic / Light Field Hybrid Head‐mounted Display was proposed to avoid accommodation — convergence conflict and improve the resolution of light field image. This new system generate images in LF and stereoscopic mode, further producing hybrid images by the visual persistence of human eyes. To build a mechanism for the time‐multiplexing of the polarized light, we designed and fabricated a micro‐lens array with the liquid crystal material. Specifically, with the function of TN cell and LC MLA, Hybrid HMD could time‐multiplex two images in flicker‐free frame rate. In our results, the resolution of hybrid image can be significantly enhanced from 5.5 ppd to 10 ppd in horizontal direction and 6.2 ppd to 15.9 ppd in vertical direction. [ABSTRACT FROM AUTHOR]

SPATIAL light modulators ,DIGITAL holographic microscopy ,THREE-dimensional display systems - Abstract
The new encoding methods are proposed and demonstrated for amplitude‐only computer‐generated hologram (CGH). Traditionally, the amplitude‐only encoding method proposed by Burch, has been used over 50 years, because it is the deterministic solution for generating an ideal hologram added by its conjugated hologram. Since the amplitude‐only hologram cannot represent negative values, the result of Burch's encoding should always be added by some values, so that none of data is less than zero. It means that the electric‐field of zero amplitude mapped into the medium gray level in a spatial light modulator (SLM). In ideal holographic display, it does not cause any problem on reconstructing holograms, but the medium gray level actually adds the noise at the practical holographic display. We introduce the encoding methods which can map the zero amplitude into the zero gray level. These encoding methods can increase the contrast ratio of an amplitude‐only hologram by reducing unnecessary scattering and stray lights. [ABSTRACT FROM AUTHOR]

THREE-dimensional display systems ,LIQUID crystals - Abstract
A multi‐electrode Fresnel‐type 2D/3D switchable display with novel structure LC lens is proposed which may achieve faster switching speed and low cross‐talk in the 3D displays by applying a discontinuous non‐uniform electric field. Furthermore, a scanning type 3D display with impulsive driving collimate backlight is proposed to solve the resolution degradation problem and decrease the dynamic crosstalk of 3D perception. A scanning prism with polymer‐stabilized blue phase liquid crystals (PS‐BPLCs) was demonstrated with an impulsive blinking backlight system of high‐resolution 3D display. The fast switching PS‐BPLC prism, whose response time was less than 1 ms, may solve the resolution degradation problem for the autostereoscopic display. [ABSTRACT FROM AUTHOR]

THREE-dimensional display systems ,AUGMENTED reality - Abstract
Augmented reality (AR) technology, which integrates virtual computer‐generated information into the real world scene, is believed to be the next‐generation human‐machine interface. However, most AR products adopt stereoscopic 3D display technique, which causes the accommodation‐vergence conflict. To solve this problem, we have proposed two approaches. The first is a multi‐planar volumetric display using fast switching polymer‐stabilized liquid crystal (PSLC) films. By rapidly switching the films between scattering and transparent states while synchronizing with a high‐speed projector, the 2D slices of a 3D volume could be displayed in time sequence. We delved into the research on developing high‐performance PSLC films in both normal mode and reverse mode; moreover, we also realized the demonstration of four‐depth AR images with correct accommodation cues. For the second approach, we realized a holographic AR display using digital blazed gratings and a 4f system to eliminate zero‐order and higher‐order noise. With a 4k liquid crystal on silicon device, we achieved a field of view (FOV) of 32 deg. Moreover, we designed a compact waveguide‐based holographic 3D display. In the design, there are two holographic optical elements (HOEs), each of which functions as a diffractive grating and a Fresnel lens. Because of the grating effect, holographic 3D image light is coupled into and decoupled out of the waveguide by modifying incident angles. Because of the lens effect, the collimated zero order light is focused at a point, and got filtered out. The optical power of the second HOE also helps enlarge FOV. [ABSTRACT FROM AUTHOR]

ELECTROENCEPHALOGRAPHY ,THREE-dimensional display systems ,ELECTRODES - Abstract
3D display has become increasingly popular in many fields. It can provide incredible immersion compared with 2D display. There are many researches referring to the change of user about no matter subjective experience or objective physiology signal while watching 3D content. Similarly, in this paper, we study the variation of user's EEG when the user watched 3D content. However, we only focus on parallax cue and avoid other cues of 3D content by using Random Dot Stereogram(RDS) as visual stimulus. We designed an experiment which asked the subject to watch RDS with nine kinds of parallaxes(0,±0.5,±1.1,±1.3,±1.7). The users watched one RDS for 1 minute and then closed eyes and rest for 1 minute every time. During watching, EEG signal with 30‐channel was recorded. The result suggests that significant variation of the user's EEG data occurred in the Alpha (8–13Hz) and Beta(14–30Hz) frequency band by different parallax's comparison. And we found not only parallax but also electrode position can impact the user's EEG data significantly. Accurately, the EEG data has a significant change in six electrodes position in both frequency bands including CZ, PZ, OZ, O2 in international 10–20 system. It means those electrode positions we detect can be regarded as typical positions where we record EEG signal. It will simplify the process of EEG signal acquisition when we need to study the relationship between parallax cue of 3D display and the user further. [ABSTRACT FROM AUTHOR]

With the development of ultra‐high definition (UHD) display technology and stereoscopic 3D display technology, 3D ultra‐high monitor will help surgeons obtain the spatial hierarchy of internal tissues, identify tissue surfaces and blood vessels clearly, locate the focus precisely and reduce surgery time. Compared with normal 2D medical monitors, 3D medical monitors will lose more brightness because of the 3D application, so it is necessary to design a high‐brightness backlight system to guarantee the display stability and the accuracy of the diagnosis. This paper presents a novel processing system for 4K UHD 3D medical monitor with the architecture combined with universal SOC (System on a Chip) and specialized FPGA (Field Programmable Gate Array). It is designed that a hardware system with high efficiency and reliable brightness stability control for small and medium sized monitors. Furthermore, we analyze the two dimming modes of linear dimming and PWM dimming for a better application in medical monitor. [ABSTRACT FROM AUTHOR]

THREE-dimensional display systems ,3-D video (Three-dimensional imaging) - Abstract
The main benefit of 3D display over 2D display is the obvious ability to create a more lifelike character with high depth sense. However, the limitation of human eye's visual mechanism, unartful 3D scene structure design, or bad viewing condition always emerges poor depth perception experience or even physiological discomfort during the watching time, which is often sub‐optimal for mass high‐quality 3D display productions. To solve this problem, we propose a novel 3D display parallel system for depth sense optimization and it empirically guides how the light field should be re‐rendered. Structurally, the parallel system consists of an artificial perception measurement system, a display evaluation model and a light field display rendering system, which includes the display calibration, scene capture, light field data processing and display. Particularly, the system can systematically analyze and model various factors affecting the depth sense which learned through the measurement system, like scene structure, objects' speeds in 3D video and so on. And those sense factors can be personally modified or increased according to the viewer's demands or technical improvement. Moreover, the light field could be real‐time re‐rendered, based on some image processing technology, optical flow analysis and object segmentation (or tracking) (especially the one‐shot video segmentation). Theory and algorithms are developed and experimental validation results show a superior performance. [ABSTRACT FROM AUTHOR]
