A. K. Srivastava, L. Shi, H.-S. Kwok (Hong Kong Univ. of S&T, Hong Kong )

We disclose a 3-in. 250 ppi active matrix field sequential color display panel based on electrically suppressed ferroelectric liquid crystal (FLC). FLC's fast response time under low operation voltage (~10 µs at 6.67 V/µm) enables field sequential color display operations with 60 Hz frame rate and 360 Hz FLC driving frequency. The specific 3T1C pixel circuit is designed to generate a continuous grayscale from FLC binary switching mechanism by utilizing pulse width modulation concept.

OLEDp1 - 16L Full Roll-to-Roll Fabrication Process of Large-Area Flexible OLED with Silver-Nanowire Transparent Electrode
C. Kim, S. Jeong, S. M. Cho (Sungkyunkwan Univ., Korea )

Large-area flexible OLED panels were fabricated by a roll-to-roll thermal evaporator. The panels were fabricated on the silver-nanowire embedded flexible transparent electrode with barrier layer inserted between electrode and PET substrate. The barrier layer was composed of the organic polymer layer and inorganic Al₂O₃ layer. Organic polymer layer was deposited by plasma-enhanced chemical vapor deposition (PECVD) and the inorganic Al₂O₃ layer was deposited with atomic layer deposition (ALD). Both depositions were carried out in a vacuum roll-to-roll equipment. All fabrication process for OLED panels were a roll-to-roll process which could reduce the process time and cost.

T. Fukiage, T. Kawabe, S. Nishida (NTT, Japan )

When a conventional stereoscopic display is viewed without 3D glasses, image blurs, or 'ghosts', are visible due to the fusion of stereo image pairs. We overcome this limitation by synthesizing ghost-free stereoscopic images based on phase-based control of stereo disparity.

The depth of the viewing zone becomes deep by applying time-division quadruplexing when the observer is close to the display while applying time-division triplexing when the observer is far from the display.

We use a depth camera for eye tracking. Its viewing area is extremely expanded by dividing single screen into multiple areas and controlling binocular images positions of each area. Therefore, the viewer does not need to keep optimum viewing distance. You can enjoy high quality stereoscopic images in a very wide range.

We have developed a flexible pipeline from a single-view camera to a layered light-field display. We obtain from the camera not only a color image but also a depth map with the aid of structured illumination. Using these information, we synthesized multi-view images and displayed them on the layered display. We developed a flexible pipeline consisting of depth estimation with structured illumination, depth-image-based rendering, refinement using a CNN and conversion to the layer patterns for the light-field display. Through the simulations and experiments, we demonstrated that our pipeline works well.

A typical e-Tile configuration, in which 100 pixels are mounted on a 100 mm square board, was designed and prototyped. A demonstration of arrayed “e-Tile” will be shown in I-DEMO session. Special features of “e-Tile” is its low power consumption, low panel cost, and light weight. One promising application of “e-Tile” is an unobtrusive information board, which is far less annoying than the conventional vivid LED/LCD in public spaces.

The display prototypes show feasibility of robust large area MEMS manufacturing process with existing display manufacturing equipment. The audiences can enjoy the simple (full display requires only 6 lithographic masks) yet highly efficient (more than 30% light transmission) display without any lossy elements (e.g. color filter, polarizer).
