We have developed a 470 x 235ppi poly-Si TFT LCD with a novel pixel arrangement, called HDDP (Horizontally Double-Density Pixels), for high-resolution 2D and 3D autostereoscopic display. 3D image quality is especially high in a lenticular-lens-equipped 3D mode because both horizontal resolution and vertical resolution are high, and because these resolutions are equal. 3D and 2D images can be displayed simultaneously in the same picture. In addition, 3D images can be displayed anywhere and 2D characters can be made to appear at different depths with perfect legibility. No switching of 2D/3D modes is necessary, and the design's thin and uncomplicated structure makes it especially suitable for mobile terminals.

We have developed a 2D/3D time sequential LCD autostereoscopic display, which is capable of simultaneous displaying 2D and 3D graphics at a frame rate up to 120 Hz. Left and right sets of viewing zones are formed by a combination of a fast LC shutter and a lenticular lens array.

This paper describes current work regarding two EC funded projects, MUTED and HELIUM3D whose objective is to produce an autostereoscopic display system which is well suited to domestic television applications. Both of these projects have common roots in a previous EC funded project (ATTEST) and both employ laser illumination and viewer head tracking.

We present a multi-view autostereoscopic display system based on volume holographic storage technique. In this proposed system, the interference pattern of spatial multiplexed plane reference and angular multiplexed plane object beams are recorded into a photorefractive crystal, which plays a role of guiding object beams of multi-view images into the desired persfective directions. For reconstruction, object beams containing the desired multi-view image information, which satisfy Bragg matching condition, are illuminated in the time-division multiplexed manner onto the crystal. Then multiple stereoscopic images are Projected to the display plane for autostereoscopic 3D viewing.

This research presented an implementation of autostereoscopic virtual three-dimensional (3D) button device as non-contact style. The proposed device has several characteristics about visible feature, non-contact use and artificial intelligence (AI) engine. The device was designed to be contactless to prevent virus contamination and consists of 3D buttons in a virtual stereoscopic view. To specify the button pressed virtually by fingertip pointing, a simple deep learning network having two stages without convolution filters was designed. As confirmed in the experiment, if the input data composition is clearly designed, the deep learning network does not need to be configured so complexly. As the results of testing and evaluation by the certification institute, the proposed button device shows high reliability and stability.

An autostereoscopic multi-view 3D display system has the narrower degrees of freedom in the observational directions, such as the horizontal and perpendicular directions to the display plane, than the glasses-on type of 3D display. In this paper, we propose an innovative method to expand the width of the viewing zone formed in the depth direction while maintaining the number of views in the horizontal direction by using a triple segmented-slanted parallax barrier (TS-SPB) in the glasses-off type of 3D display. The validity of the proposal was verified by an optical simulation based on an environment similar to an actual case. The maximum number of views that can be displayed in the horizontal direction is 2n, and the width of the viewing zone with depth increased up to a factor of 3.36 compared to the existing one-layered parallax barrier system.

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.

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.
