4. The method of claim 3 , wherein the second angle is greater than the first angle.

5. The method of claim 1 , wherein the normal mode trigger is selected from a list including a location of the information handling system, presence tag settings, calendar items, document based privacy settings, and user commands.

6. The method of claim 1 , wherein the privacy mode trigger is selected from a list including a location of the information handling system, presence tag settings, calendar items, and user commands.

7. A method comprising:

emitting light on both sides of a normal mode prism configuration within a display, by normal mode backlight light emitting diodes located on both sides of the normal mode prism configuration, on the normal mode prism configuration while the display is in a normal mode, wherein first prism angles in the normal mode prism configuration are distinct from second prism angles in a privacy mode prism configuration;

determining, by a processing device of an information handling system, whether a first trigger based on a first triggering event of a plurality of triggering events is detected, wherein the first trigger is a normal mode trigger associated with the display;

providing an image in the normal mode of the display in response to the first trigger being detected unless second trigger based on a second triggering event of a plurality of triggering events is detected, wherein the second trigger is a privacy mode trigger associated with the display;

determining, by the processing device of the information handling system, whether the privacy mode trigger associated with the display is detected, wherein the privacy mode trigger is detected based on the second triggering event, wherein the second triggering event is based on a plurality of pre-defined locations stored in a memory, wherein one of the pre-defined locations matches a location of the information handling system;

determining whether to provide a prompt to a user to determine whether the user accepts a display mode change;

switching a display mode of the image on a screen of the display between the normal mode and a privacy mode in response to the privacy mode trigger being detected and in response to the determining not to provide the prompt to the user; and

emitting light on both sides of the privacy mode prism configuration within the display, by privacy mode backlight light emitting diodes located on both sides of the privacy mode prism configuration, on the privacy mode prism configuration while the display is in the privacy mode, wherein the privacy mode backlight emitting diodes are distinct from the normal mode backlight light emitting diodes and both are located on each side of the display.

8. The method of claim 7 , further comprising:

in response to the determining to provide the prompt to the user, providing the prompt to the user to determine whether the user accepts the display mode change prior to switching to the privacy mode; and

receiving a display mode change verification prior to switching to the privacy mode.

9. The method of claim 7 , wherein switching to the privacy mode comprises:

reducing a number of backlight portions powered on in the display, wherein reducing the number of backlight portions reduces a size of the image on the screen.

10. The method of claim 9 , wherein reducing the number of backlight portions powered on creates a power savings in the display during the privacy mode.

11. The method of claim 7 , wherein a viewable angle of the image in the privacy mode is from a reference line of the display to a first angle measured from the reference line, and the viewable angle of the image in the normal mode is from the reference line to a second angle measured from the reference line.

12. The method of claim 11 , wherein the second angle is greater than the first angle.

13. The method of claim 7 , wherein the privacy mode trigger includes calendar items, document based privacy settings, and user commands.

14. An information handling system comprising:

a processing device to detect a privacy mode trigger, to determine whether to provide a prompt to a user to determine whether the user accepts a display mode change, and to provide a privacy mode control signal in response to detecting the privacy mode trigger and in response to determining not to provide the prompt to the user; and

a display including:

a screen to provide an image;

a normal mode prism configuration located behind a privacy mode prism configuration within the display, wherein the normal mode prism configuration is distinct from the privacy mode prism configuration;

the privacy mode prism configuration located closer to the screen than the normal mode prism configuration within the display;
