Abstract
Apparatus and method of reducing light leakage from display devices are described. An embodiment of reducing light leakage from display devices includes providing an optical shutter that is configured to block light from a display device from being emitted into the ambient environment when the display device is in a bright state and configured to display visual information to the user. The optical shutter can be configured to transmit light from the ambient environment to the user when the display device is not displaying visual information.
