This paper introduces an e-Privacy display, electrically switchable between wide viewing angle (share) mode and narrow viewing angle (privacy) mode. Pixel electrodes are divided into two domains, one part is the normal display area, and the other part is the privacy area. By controlling the privacy area electrode, viewing angle switching can be realized.
