Enhancement of the perceived image quality of a 2D/3D convertible directional-backlight unit system using a double-slit barrier array and an active diffuser

Abstract

In this paper, a method to construct a directional-backlight unit system to separate the left-eye image and the right-eye image by adopting a double-slit barrier array is proposed to enhance the perceived quality of the realized 3D image. Additionally, the two-dimensional/three-dimensional convertible function is also realized by adopting an active diffuser to the spatial interlacing directional-backlight system.

Low-Threshold-Voltage and Electrically Switchable Polarization-Selective Scattering Mode Liquid Crystal Light Shutters

“…Moreover, the contrast ratio of the [7:3]-PDLCs NBA107 is ~9. Accordingly, the [7:3]-PDLCs NBA107 with low power consumption has considerable potential to be applied in the various areas of optics [1,2,3,4,5,6,7,8,9,10,11,12]. The scattering performances of the PSMLS mainly driven by in-plane and/or vertical fields with low V th were also demonstrated.…”

“…Optical devices based on polymer-dispersed liquid crystals (PDLCs) have been studied worldwide for several decades because of their electrically switchable light-scattering properties [1,2]. PDLCs can be applied to light shutters, 2D/3D switching, displays, holographic gratings, optical retardations, and so forth [1,2,3,4,5,6,7,8,9,10,11,12]. Polymers and liquid crystals (LCs) with a proper weight ratio are initially well-mixed with each other, and LC droplets can be formed in a continuous polymer matrix through polymerization-induced phase separation (PIPS) after treatment with UV illumination for a certain duration [1,2].…”

14.3: See‐through 2D/3D Compatible Display Based on Integral Imaging

“…The see-through 2D/3D compatible display screen is consisted of a LAHOE film and a PDLC film, and the PDLC film is tightly behind the LAHOE film. The PDLC film can operate at two different modes the scattering and transparent mode [11]. The PDLC material is composed of liquid crystal (LC) molecules which encapsulated by polymer.…”
