3-D mobile display based on dual-directional light guides with a fast-switching liquid-crystal panel

Abstract

An autostereoscopic display based on dual-directional light guides with a fast-switching liquid-crystal panel was designed and fabricated to provide better 3-D perception with image qualities comparable to that of 2-D displays. With two identical micro-grooved light guides, each with a light-controlled ability in one direction, two restricted viewing cones are formed to project pairs of parallax images to the viewer's respective eyes sequentially. Crosstalk of less than 10% located within +/- 8 degrees-+/- 30 degrees and an LC response time of 7.1 msec for a 1.8- in. LCD panel can yield acceptable 3-D perceptions at viewing distance of 5.6-23 cm. Moreover, 2-D/3-D compatibility is provided in this module.
