  • providing at least first and second display layers, said first display layer being disposed in relationship to said second display layer in a position between said second display layer and a viewing area for viewing images displayed by said first and second display layers, said first display layer being transmissive to images displayed by said second display layer, and the viewing area comprising at least first and second different viewing locations located within the viewing area;

    providing an information handling system coupled to each of said first and second display layers, said information handling system comprising at least one processor configured to process an image file and to selectably display an image from said image file on either of one of said first or second display layers;

    processing a first image file with said information handling system for display of a first image from said image file;

    selectably displaying said first image from said first image file on said second display layer or only on said first display layer based on at least one of a file characteristic of said first image file, a user input, or a combination thereof;

    wherein an image displayed on said second display layer is visible at the second viewing location in the viewing area without further polarization after it passes through said first display layer;

    wherein an image displayed on said first display layer comprises one or more portions of light that are polarized relative to background light displayed on said first display layer such that said image is only visible at the first viewing location in the viewing area when it is cross polarized relative to the polarization of said one or more portions of light; and

    wherein said step of selectably displaying said first image comprises selectably displaying said first image only on said first display layer based on at least one of a file characteristic of said first image file, a user input, or a combination thereof; and

    wherein said method further comprises;

    providing at least a first human user and a second human user simultaneously positioned at the respective different first and second viewing locations within the viewing area,processing a second image file with said information handling system for display of a second image from said second image file,selectably displaying said second image from said second image file on said second display layer based on at least one of a file characteristic of said second image file, a user input, or a combination thereof, andsimultaneously displaying the first image on said first display layer while said second image is displayed on said second display layer so that each of said first image and said second images are simultaneously visible to the first human user at the first viewing location in the viewing area when cross polarized relative to the polarization of said one or more portions of light, and so that at the same time only the second image is visible to the second human user at the second viewing location in the viewing area without further polarization.
