Stereoscopic display device with changeable barrier pattern

Abstract

A stereoscopic display device with changeable barrier patterns includes a display panel and a parallax barrier device. The parallax barrier device is disposed on the display panel. The parallax barrier device includes a first substrate, a second substrate, a liquid crystal layer, and a plurality of barrier pixels. The first substrate and the second substrate are disposed oppositely to each other, and the first substrate is disposed between the display panel and the second substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. Each of the barrier pixels includes at least one switch device for independently controlling each of the barrier pixels to generate a changeable barrier pattern.
