Abstract:
1. A stereoscopic display, comprising: a backlight module, for generating light; a polarizer film, disposed on the backlight module, for converting polarized light from the backlight module into light along a first direction; a transparent substrate, disposed on the polarizer film, a plurality of electrodes being disposed on the transparent substrate, each of the plurality of electrodes extending along a second direction, the second direction being different from the first direction; and a liquid crystal layer, disposed on the transparent substrate, an alignment of liquid crystal molecules in the liquid crystal layer varying according to voltage applied on the plurality of electrodes; and a retard unit, disposed between the transparent substrate and the polarizer film, for converting the polarized light from the polarizer film into light along a third direction, the third direction being different from the first direction and the second direction; wherein the plurality of electrodes comprise a first electrode, a second electrode, and a third electrode, the second electrode is disposed between the first electrode and the third electrode, and the stereoscopic display shows 3D images when an optical axis of the liquid crystal molecules near the first electrode and the third electrode is in parallel with a direction of transmission of the light from the polarizer film and when the optical axis of the liquid crystal molecules near the second electrode is in parallel with a polarization direction of the light from the polarizer film.
