73-2: A Wide View Glass-less 3D Display with Head-Tracking System for Horizontal and Vertical Directions

Abstract

In this study, a glass-less 3D display with a head-tracking system for horizontal and vertical directions was developed. Based on the viewer's head position, the barrier pitch and the position of the barrier aperture were optimized. This resulted in the expansion of the 3D viewing zone in a vertical direction from the display surface to the distance of "320 -1016 mm", and in the horizontal direction from the center of the display at a "r267 mm" distance.

54‐2: A Measurement‐Based Image Compositing for 3D Head‐Up‐Display

“…The picture assignments for the right eye and the left eye for the eye position (Ex, Ey, Ez) to get stereoscopic display can be obtained by a formula from the optical design [1]. Here, since the eye position should be based on the coordinate of the virtual image display, the eye position coordinates once based on the coordinate of eye-tracking camera position should be converted to the coordinates based on the virtual image display [3].…”

“…HUDs is progressing, and in addition to with the wide viewing angle and larger screens, higher functionality such as AR HUDs and 3D HUDs is being considered. 3D displays using parallax barrier or lenticular can expand the viewing zone by using eye tracking [1][2]. Real-time 3D display can be obtained by appropriately performing image composition and subpixel rendering for the eye position in the enlarged viewing zone.…”

21‐4: Newly Developed Light Field Display with Ultra‐Wide Viewing Angle and High Resolution

“…Glassless 3D displays, which do not require special glasses for viewing 3D images purposes, have recently attracted attention. We developed a glassless 3D display with a headtracking system, which has high 3D resolution and a wide viewing angle [1][2][3][4][5]. In this system, first, an image of the viewer's head is captured by a sensor, e.g., a camera.…”

61‐3: Glasses‐Free 2D/3D Switchable Display Using a Trapezoidal Light‐Extraction (TLE) Film on the Light‐Guide Plate

“…The autostereoscopic display creates a 3D image by separating the image into left eye and right eye components without using glasses and normally uses parallax barriers or lenticular lenses. To convert a screen in 2D mode to 3D mode without requiring any glasses, liquid crystal (LC) based parallax barriers and lenticular lenses have been proposed [2][3][4][5][6][7][8]. However, when using additional LC-based optical components, the thickness of the display panel, power consumption, and fabrication cost are greatly increased, which imposes a large burden, especially for mobile applications.…”
