SWITCHABLE PRIVACY FILTER |
摘要 |
The disclosure generally relates to optical elements such as switchable privacy filters useful for displaying information in at least two modes. In the first mode, the viewing angle can be limited to restrict viewing to near-normal orientations. In the second mode, the viewing angle can be increased so that the information can be viewed at larger oblique angles. The disclosure also relates to switchable privacy displays that include the switchable privacy filters.
