1. A method of displaying images, comprising:
- 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.

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.

14. A method of displaying images, comprising:
-
providing at least first and second display layers, said first display layer being disposed in spaced 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; displaying an image on at least one of said first or second display layers; wherein an image displayed on said second display layer is visible in the viewing area without further polarization after it passes through said first display layer and said first polarizing 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 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 displaying comprises simultaneously displaying a first image to a first user positioned in the viewing area on said first display layer and a second image to a second user simultaneously positioned in the viewing area on said second display layer, each of said first image and said second images being simultaneously visible to said first user 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 said second image is visible to said second user in the viewing area without further polarization. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. An information handling system configured for coupling to a display system or a projection system, said information handling system comprising:
-
at least one processor configured to process a first image file, said at least one processor being configured to selectably provide image data from said first image file for either of; display of an image on a second display layer of said display system to a viewing area or for projection by a second projection assembly of said projection system to the viewing area, such that the image displayed on the second display layer or projected by the second projection assembly is visible in the viewing area without further polarization, or only for display of an image on a first display layer of said display system to the viewing area or only for projection by a first projection assembly of said projection system to the viewing area, such that the image displayed on the first display layer or projected by the first projection assembly comprises one or more portions of light that are polarized such that said image is only visible in the viewing area when it is cross polarized relative to the polarization of said one or more portions of light; and an image display application configured to execute on said at least one processor and to select said first image based on identification of said file characteristic of said image file, said user input, or a combination thereof as either of; a publicly viewable file for display on said second display layer or for projection on said second projection assembly, or a privately viewable file for display only on said first display layer or for projection on said first projection assembly; and where the image display application is further configured to simultaneously display or project the first image to a first user positioned in the viewing area on the first display layer or first projection assembly and the second image to a second user simultaneously positioned in the viewing area on the second display layer or second projection assembly, such that each of the first image and the second image are simultaneously visible to the first user in the viewing area when cross polarized relative to the polarization of the one or more portions of light, and so that at the same time only the second image is visible to the second user in the viewing area without further polarization. - View Dependent Claims (23, 24, 25, 26, 27)
