Displays with privacy control

A display system for an enclosed space, the display system comprising:

• a sensor configured to detect a level of an external illuminance in an external environment outside the enclosed space;
• a display inside the enclosed space and configured to provide an output at a brightness;
• and
• a window separating the enclosed space from the external environment, the window having an adjustable transmissivity for controlling an amount of light transmitted through the window, wherein the window is configured to adjust the transmissivity based on the level of the external illuminance in the external environment and the brightness of the display, wherein the output comprises content having a privacy threshold, the privacy threshold being based on a characteristic of the content and wherein the display is further configured to:
• determine whether the privacy threshold is satisfied based on the level of the external illuminance, the brightness of the display, and the transmissivity of the window;
• and
• if the privacy threshold is not satisfied, change the output of the display.
