We have developed a 2D-3D convertible 7" autostereoscopic mini-monitor with high 3D quality, in which the parallax barrier LCD is attached on the TFTLCD. The excellent optical performance was achieved by design of the ghost free barrier and precise assembly between the barrier layer and the TFT-LCD panel. Our design principle and fabrication technology suppressed 3D cross-talk and improved viewing angle. In this paper, the design and fabrication process of the 3D mini-monitor are described. The evaluation for the 3D performance is also discussed.

In this letter, we propose a dual autostereoscopic display platform employing a natural interaction method, which will be useful for sharing visual data with users. To provide 3D visualization of a model to users who collaborate with each other, a beamsplitter is used with a pair of autostereoscopic displays, providing a visual illusion of a floating 3D image. To interact with the virtual object, we track the user's hands with a depth camera. The gesture recognition technique we use operates without any initialization process, such as specific poses or gestures, and supports several commands to control virtual objects by gesture recognition. Experiment results show that our system performs well in visualizing 3D models in real-time and handling them under unconstrained conditions, such as complicated backgrounds or a user wearing short sleeves.

This paper describes low temperature poly-Si (LTPS) TFT system on glass (SOG) technology developed in NEC. High resolution SOG-LCDs such as a 230 ppi reflective type LCD, a 2.5", 333 ppi 2D/3D autostereoscopic LCD, and a 2.1" single voltage driven full integration LCD for mobile applications and a 0.9", XGA light valve for projectors are reviewed from the perspective of the high resolution technologies

Since the invention of 'the Stereoscope' in 1838, many kinds of 3D display systems have been developed and used for various applications. In fact they have been at least proposed for virtually every application that uses 2D displays. In this paper, we introduce the various 3D display techniques and its products.

Define a designated eye position (DEP) for the 3D displays is a critical issue. It shows the system performance without content issue. We use luminance meter to capture these optical characteristic and discuss between one point measurement, two points measurement and three points measurement situation.

We present a novel head tracking system for stereoscopic displays that ensures the viewer has a high degree of movement. The tracker is capable of segmenting the viewer from background objects using their relative distance. A depth camera using TOF(Time-Of-Flight) is used to generate a key signal for eye tracking application. A method of the moving parallax barrier is also introduced to supplement a disadvantage of the fixed parallax barrier that provides observation at the specific locations.

Crosstalk has been regarded as one of inherent problems in a factor disturbing optimal viewing experiences. For this reason, display developers address the crosstalk issues. However, due to various display characteristics and viewing environments it is hard to estimate the crosstalk generated in real space. This paper proposes an interactive multi-view display simulator based on augmented reality for developing mobile autostereoscopic displays. This display simulator can be used for the developers to estimate the crosstalk and find optimal viewing zone intuitively. Typical parameters for mobile phone use are applied for the estimation. The proposed simulator provides visualized crosstalk in real space for them to determine better viewing zone interactively. The proposed system is expected to help establish ergonomic guidelines for mobile multi-view autostereoscopic display developers, designers, and viewers.

Observers usually experience visual fatigue when they watch contents displayed on 3D display. There has been various research on visual fatigue incurred in stereoscopic displays that use 3D glasses, but relatively less studies have been done in the area of autostereoscopic displays. i3D system refers to interactive 3D system that makes it possible for users to interact with contents using their hands. Current research measured visual fatigue that users experience from i3D under various visual environments. We examined the effects of viewing distance, disparities and visual orientation on visual fatigue in i3D. The results indicated that visual fatigue decreased with longer distance and smaller disparity. Visual fatigue increased with angle when 3D fusion was unstable. In addition, there was an interaction effect between angle and distance in which visual fatigue increased with distance under stable 3D fusion but there was no difference in visual fatigue as a function of distance when 3D fusion was unstable. These results would be importantly used to develop autostereoscopic displays that minimize visual fatigue.

A natural 3D image is considered by many people to be next-step in evolution of displays. This paper introduces autostereoscopic 3D of 60-view number, which is made using slanted lenticular lens array and LCD of 15.1 inch diagonal size and 3200 by 2400 pixel numbers and presents the results of our prototype. Due to its large view number, smooth motion parallax is observed and the visual fatigue is reduced.

In this paper, we explained characteristics of integral imaging microscope using point light source. To display the bio-medical information, which is captured as a form of the elemental images, using autostereoscopic displays, the characteristics analysis of three-dimensional information is required. For integral imaging microscope using point light source array, the elemental image capturing configuration has to satisfy a specific condition. We explain the condition to capture the elemental images and show the experimental results.
