Abstract: Disclosed herein are techniques related to privacy and touch at display devices. The techniques include an apparatus having a touch sensitive electroactive privacy layer of a display device. The touch sensitive electroactive privacy layer is configured to restrict a propagation direction of light emission associated with a display layer of the display device and to register or a touch event. The restriction of propagation is generated by micro louvers formed between privacy layer electrodes in the touch sensitive electroactive privacy layer while the registration of the touch event is detected by mutual capacitance between a touch electrode and one of the privacy layer electrodes.
