The processing device detects a privacy mode trigger, and provides a privacy mode control signal in response to detecting the privacy mode trigger. The display includes a screen to provide an image, and a backlight control module. The backlight control module controls a brightness of the image based on a display mode of the display, and provides the image in a privacy mode in response to receiving the privacy mode control signal. ## Claims ### Claim 1 A method comprising: providing an image on a screen of a display of an information handling system, wherein brightness of the image is controlled by a backlight of the display; detecting, by a processing device of the information handling system, a privacy mode trigger associated with the display; and providing, by a backlight control module, the image in a privacy mode of the display in response to the privacy mode trigger being detected. ### Claim 2 (depends on 1) The method of claim 1, further comprising: providing a prompt to a user to determine whether the user accepts a display mode change prior to providing the image in the privacy mode; and receiving a display mode change verification prior to providing the image in the privacy mode. ### Claim 3 (depends on 1) The method of claim 1, further comprising: detecting, by the processing device, a normal mode trigger associated with the display; and providing, by the backlight control module, the image in a normal mode of the display in response to the privacy mode trigger being detected. ### Claim 4 (depends on 3) The method of claim 3, 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. ### Claim 5 (depends on 4) The method of claim 4, wherein the second angle is greater than the first angle. ### Claim 6 (depends on 3) The method of claim 3, wherein the normal mode trigger is selected from a list including a location of the information handling system, calendar items, document based privacy settings, and user commands. ### Claim 7 (depends on 1) The method of claim 1, wherein the privacy mode trigger is selected from a list including the location of the information handling system, calendar items, document based privacy settings, and user commands. ### Claim 8 A method comprising: determining, by a processing device of an information handling system, whether a privacy mode trigger associated with a display is detected; and switching, by a backlight control module, a display mode of an image on a screen of the display between a normal mode and a privacy mode in response to the privacy mode trigger being detected. ### Claim 9 (depends on 8) The method of claim 8, further comprising: providing a prompt to a user to determine whether the user accepts a display mode change prior to switching to the privacy mode; and receiving a display mode change verification prior to switching to the privacy mode. ### Claim 10 (depends on 8) The method of claim 8, 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. ### Claim 11 (depends on 10) The method of claim 10, wherein reducing the number of backlight portions powered on creates a power savings in the display during the privacy mode. ### Claim 12 (depends on 8) The method of claim 8, 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. ### Claim 13 (depends on 12) The method of claim 12, wherein the second angle is greater than the first angle. ### Claim 14 (depends on 8) The method of claim 8, wherein the privacy mode trigger is selected from a list including a location of the information handling system, calendar items, document based privacy settings, and user commands. ### Claim 15 An information handling system comprising: a processing device to detect a privacy mode trigger and, to provide a privacy mode control signal in response to detecting the privacy mode trigger; and a display including: a screen to provide an image; and a backlight control module in communication with the processing device, the backlight control mode to control a brightness of the image based on a display mode of the display, and to provide the image in a privacy mode in response to receiving the privacy mode control signal. ### Claim 16 (depends on 15) The information handling system of claim 15, the screen to provide a prompt to a user to determine whether the user accepts a display mode change prior to the image being provided in the privacy mode, and the processing device to receive a display mode change verification prior to the image being provided in the privacy mode. ### Claim 17 (depends on 15) The information handling system of claim 15, the processing device to detect a normal mode trigger associated with the display, and the backlight control module to provide the image in a normal mode in response to the privacy mode trigger being detected. ### Claim 18 (depends on 15) The information handling system of claim 15, wherein the display further includes a plurality of backlight portions, the backlight control module to power on all of the backlight portions when the display is a normal mode, and the backlight control module to power on less than all of the backlight portions when the display is the privacy mode. ### Claim 19 (depends on 18) The information handling system of claim 18, wherein the display uses less power while in the privacy mode than in the normal mode based on less than all of the backlight portions in the display being powered on in the privacy mode. ### Claim 20 (depends on 15) The information handling system of claim 15, wherein the privacy mode trigger is selected from a list including triggered a location of the information handling system, calendar items, document based privacy settings, and user commands.
