Two‐parallax‐barriers‐based autostereoscopic liquid‐crystal display without cross‐talk

Abstract

Abstract— An autostereoscopic liquid‐crystal display (LCD) consists of two parallax barriers and an LCD including a liquid‐crystal panel, and a backlight panel is proposed. Parallax barrier 1 is located between the backlight panel and the liquid‐crystal panel, and Parallax barrier 2 is located between the liquid‐crystal panel and viewers. The operation principle of the autostereoscopic display and the calculation equations for the parallax barriers are described in detail. The autostereoscopic LCD was developed and produces high‐quality stereoscopic images without cross‐talk at the optimal viewing distance and less cross‐talk than a conventional one based on one parallax barrier at other viewing distances.

High resolution parallax barrier 3D display based on a sub-display-panel with transparent slits

“…Since the parallax barrier itself doesn't provide pixels for 3D images, the 3D display based on parallax barrier often has low resolution [9]. For example, the resolution of the two views 3D display based on the conventional parallax barrier is only the half of the main display panel [10,11]. Therefore a parallax barrier 3D display based on a sub-display-panel with transparent slits (SDPTS) is proposed.…”

New elliptical parallax barrier pattern to reduce the cross talk caused by light leakage

“…Autostereoscopic displays with the parallax barrier have superior three-dimensional (3-D) display characteristics and low costs. 1,2 Autostereoscopic displays provide views for multiple viewers to perceive stereoscopic images without glasses. 3,4 A barrier with a slanted pattern has been generally used for autostereoscopic displays because it features a balanced resolution in both the horizontal and vertical directions and reduced moiré artifacts on the display screen.…”

P‐3.17: Programmable virtual illuminance modulation in directional backlight autostereoscopy

“…Thereinto, autostereoscopic displays are favored since it was invented w i t h o u t u s i n g any assisting apparatus such as glasses or helmets. There are several technological approaches to realize autostereoscopic display, including parallax barriers [1] , lenticular lens array [2] , and directional backlight autostereoscopic display (DBAD) [3] . DBAD has shown unique advantages over conventional barrier-and lenticular lens-based system because of the freedom provided for design and manufacturing by separating the illumination source with the imaging source.…”
