Abstract
A touch sensitive active privacy screen, includes an apparatus having an electroactive privacy layer (122) of a display device. The electroactive privacy layer (122) is configured to restrict a propagation direction of light emission associated with a display layer (124) of the display device. The restriction of propagation is generated by micro louvers (412) formed in the electroactive privacy layer (122).
