Privacy apparatus |
摘要 |
A privacy apparatus has a transparent substrate and a liquid crystal layer formed on the transparent substrate. A thickness of the liquid crystal layer determines a range of viewing angles for the privacy apparatus; and when the thickness is greater, the range of viewing angles is smaller. Moreover, an absorption axis of the liquid crystal layer is substantially parallel to the transparent substrate and is substantially perpendicular to the range of viewing angles.
