IDW '19 Demonstrations

LCTp5-8L Electro-Optical Properties and Stabilities of Polymer Network Liquid Crystal Films with Polymer Wall Structure
*SeYong Eom1, Da-Som Yoon2, Tae-Hoon Kwon1, Soon-Bum Kwon1, 2 (1.Hoseo University, 2.NDIS Corporation)

We will demonstrate smart window films based on polymer network liquid crystals (PNLCs) stabilized by polymer walls. Polymer walls completely separated from liquid crystals provide sufficiently high mechanical and thermal stability and excellent electro-optic properties: durable under high external pressure and bending stress and thermal shock (at 150℃), highly transparent (T>82%) off-state and highly opaque (T<10%) on-state. One can see and evaluate the electro-optical property and mechanical stability of the PNLC films with size of 19 inches. Our PNLC films are suitable for various applications, for instance in active diffuser components for displays as well as smart windows.

LCT5/FMC5-3 17-inch Laser Backlight LCD with 8K, 120-Hz Driving and BT.2020 Color Gamut
*Yoichi Asakawa1, Ken Onoda1, Hiroaki Kijima1, Shinichi Komura1 (1.Japan Display Inc.)

We will demonstrate a 17-inch 8K liquid crystal display satisfying the BT.2020 specification. The pixel density of the display is 510 ppi, while its color gamut covers 98% of that of BT.2020. The liquid crystal response time is 5 ms, which is sufficient for 120-Hz driving.

*Yujiro Takeda1, Shunsuke Kobayashi1, Shogo Murashige1, Kazuatsu Ito1, Izumi Ishida1, Shinji Nakajima1, Hiroshi Matsukizono1, Naoki Makita1 (1.SHARP Corporation)

This is the demonstration machine for the Automotive Center Information Display (CID) with the ultrawide 12.3-in. flexible OLED and touch sensor. Back-plane is adopted with the high mobility IGZO-TFT with top gate structure. Resolution of this display is 1920 x 720 x RGB (167ppi) and it showes an excellent brightness uniformity. The device shows high reliability even in tough conditions such as high temperature of 85°C to low temperature of –40°C and humidity of 90% at 60°C and remain working in good condition even after 1,000 hours.

AMD7-4L Low-Temperature IGZO Technology on Transparent Plastic Foil by Atmospheric Spatial Atomic Layer Deposition

Incorporating fingerprint security in edge-free displays requires integrating a sensor in, on or behind the display. We demonstrate an optical imager, comprising an organic photodiode (OPD) frontplane and IGZO TFT backplane, with a thin-film optical collimator that enables under-display fingerprint authentication. For high resolution, the sensor/display must be made on a thin plastic substrate, reducing the overall thickness, i.e. the finger-to-sensor distance. Spatial ALD (sALD) allows processing on transparent commodity foils such as PEN. We demonstrate a 200 ppi QVGA AMOLED display, wherein low-temperature sALD was used to deposit the IGZO semiconductor and Al₂O₃ buffer in the TFT backplane.

FMC4/LCT4-1 High-Resolution (1,000 to over 3,000 ppi) Full-Color Silicon Display for Augmented and Mixed Reality

We will demonstrate the worlds first 1053ppi full-colour micro-LED display, which we call "Silicon Display". It is a 0.38-inch colour-converted micro-LED display. Each pixel is 24 µm square and composed of RGB sub-pixels. The micro-LED array is bonded onto silicon backplane so that each sub-pixel is individually addressable. We will also demonstrate blue monochrome 3,000ppi Silicon Display. The size of this display is 0.13-inch. Each pixel is 8.4 µm square with three sub-pixels. Audiences can see the images (pictures and movies) of Silicon Display through lens, and can understand how they are used for AR or MR applications.

FMC6-3 Novel Chromakey Technology with Polarizer and Retardation Film

*Masanobu Mizusaki1, Masakazu Shibasaki1, Yuto Tsukamoto1, Tokiyoshi Umeda1, Hiroshi Tsuchiya1, Shinji Shimada1 (1.Sharp Corporation)

We will demonstrate the high reliable 12.3" ultrawide flexible OLED display. The display shows high contrast ratio, wide color gamut, and wide viewing angle toward automotive application. The image quality would keep over 10,000 hours at room temperature, and 1,000 hours at 85 °C on the basis of the empirical calculation. We developed it by optimizing organic layer materials. In addition, since the display shows high flexibility, it would be able to show the original design.

3Dp1/3DSAp1-1 Compact Binocular Holographic Head-Mounted Display Using Viewing Zone Expansion Method with Multiple Light Sources
*Kazuya Furuta1, Yuji Sakamoto1 (1.Hokkaido University)

We have developed a binocular holographic head-mounted display (HMD) for augmented reality (AR). Holographic HMDs are expected to be used in work support and so on because they can display reconstructed images at a free depth. In general, the viewing zone of holography is narrow. On the other hand, our binocular holographic HMD has the wide viewing zone due to the viewing zone expansion method with multiple light source, and it enables many users who have various pupil distance (PD) to observe reconstructed images with both eyes at the same time.

3Dp1/3DSAp1-16 Multiview Image Correction for Visually Equivalent Light Field 3D Display
*Takasuke Nagai1, Munekazu Date1, Shinya Shimizu1, Hideaki Kimata1 (1.Nippon Telegraph and Telephone Corporation)

We will demonstrate the light field display. The light field display system can provide stereoscopic images without wearing a device such as an HMD. The display assumes that viewpoints of source images are strictly parallel and equally spaced. It is however difficult to arrange multiple cameras by actually satisfying such ideal assumptions. Therefore, we propose the method to virtually parallelize multiple cameras and synthesize regularized light fields by defining the ideal rotation matrix and the ideal camera positions. In demo, we will display the corrected multiview image.

3Dp1/3DSAp1-22 Displaying Live 3-D Video from a Multi-View Camera on a Layered Display
*Yusuke Ota1, Keita Maruyama1, Ryutaroh Matsumoto1, Keita Takahashi1, Toshiaki Fujii1 (1.Nagoya University)

We present a pipeline that displays 3D videos captured by a multi-view camera (ProFUSION25) on a layered display in real time. The layered display is a kind of light field displays. To develop this pipeline, we used a convolutional neural network (CNN) that calculates a layer pattern to reduce processing time. The frame rate of the video displayed on the layered display was about 18 fps. As far as we know, this is the first real-time pipeline from a light field camera to the layered display. We will demonstrate this real-time 3D display system.

VHFp3/INPp2-1 Wearable Stick-Slip Display on Fingertip to Reproduce Rubbing Sensation
*Honoka Haramo1, Vibol Yem1, Yasushi Ikei1 (1.Tokyo Metropolitan University)

We developed a wearable stick slip display using rotating cylindrical contactor to reproduce friction sensation during rubbing a surface of material. The contactor can be rotated continuously and also vibrated by a DC motor. Fig. 1 shows the mechanism of our device. We use a force sensor to measure the rubbing sensation of a material. In the demo experience, a participant wear our device to the index finger and perceives stick slip sensation of rubbing a silicon rubber or a wood on the finger pad. Participant can compare the sensation by rubbing a real material.

PRJ4-3 New Concept Ultra Short Throw Projector for Consumer
*Ryutaro Otake1, Misa Sakurai, Masakatsu Ito, Hiroshi Nakade, Yuuji Taniue, Masaru Matsumori (1.Panasonic Corporation)

Flat panel TV gradually shifts to large screen size like 65" because the price of large screen TV goes down. However, our living space doesn't enlarge. So flat TV influences on interior design much more. To solve such kind of problems we suggested and introduced a new concept projector for consumer. To suggest super bright large screen and powerful sound for small living room like Japan, we realized that we put both large screen and powerful sound to small box. Also by using ultra short throw device and wireless function, we realized easy installation.

PRJ6/AIS3-2 Vertical View Human Action Recognition from Range Images

We have developed a reflective LCD that is able to display full-color moving image and has low power consumption. By combining a new twisted VA-LC mode, a silver alloy electrode with micro reflective structure (MRS), and IGZO-TFT technology, the prototype has achieved excellent optical properties and flicker-less 1Hz driving. In recent years, various video streaming services have been used by many people, and video files are frequently posted on social media. We expect that the new reflective LCD will improve the moving image display function required for e-books and digital signage in the future.

*Munekazu Date1, Shinya Shimizu1, Hideaki Kimata1 (1.Nippon Telegraph and Telephone Corporation)

Light field displays have limitation in display depth range and it is an issue, especially for live action applications. Though generating depth map and re-rendering is a solution, it requires huge computational cost. In this paper, we achieved depth range compression calculating only weighted average of multi-camera images. A 15.6 inch VELF3D table top display is used for the demonstration. CG and live-action movies with depth range control are displayed. Guests can see an autostereoscopic 3D movie without special devices such as HMD or 3D glasses, and feel natural existence induced by smooth motion parallax.
