Abstract
Methods and systems for displaying or projecting images that may be implemented to provide the ability for a user of an information handling system to view a selected image on a display or projection screen privately, while allowing other images to appear on the display or projection screen which are publicly viewable to other users who cannot see the privately-displayed image. With appropriate intervening polarization, a user may be allowed to view the private image as well as any displayed or projected publicly viewable images, and the private image and publicly viewable images may be optionally simultaneously displayed or projected if so desired.
