Abstract
Official abstract text for this publication.
A polarizing panel includes a first substrate, a second substrate and an interposed first liquid crystal layer. The first substrate includes a plurality of spaced apart and segment electrodes and segments of a first light-blocking member disposed within interval areas between the segment electrodes. The second substrate faces the first substrate to include a common electrode facing the segment electrodes. The first liquid crystal layer is able to selectively apply a first polarizing effect to light rays passing therethrough when in a corresponding first state and to apply a different second polarizing effect to passing through light rays when in a corresponding second state, where the first and second states can be selectively chosen by voltages applied to the segment electrodes. The light-blocking member can reduce image crosstalk lights from being emitted from the interval areas between the segment electrodes, so that a crosstalk component of a formed 3D image may be prevented or reduced due to light-blocking effects.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device comprising: a display panel configured to interleavingly display a left-eye image and a right-eye image; a light source module configured to provide the display panel with lights; a polarizing panel disposed in front of the display panel and comprising a plurality of spaced apart segment electrodes and one or more light-blocking members disposed in corresponding interval areas between adjacent ones of the spaced apart segment electrodes,…
