Abstract
Disclosed herein are techniques related to privacy at display devices. The techniques include an apparatus having an electroactive privacy layer of a display device. The electroactive privacy layer is configured to restrict a propagation direction of light emission associated with a display layer of the display device. The restriction of propagation is generated by micro louvers formed in the electroactive privacy layer.
