Abstract

Systems and methods for mitigating image degradation in displays are provided. In one example, the present disclosure relates to an information handling system comprising a display policy related to a display, where the display policy provides information concerning: (1) at least one icon for display on the display, and (2) a schedule for changing a size of the at least one icon over a period of time. The system may further include an image data storage configured to store image data corresponding to the at least one icon for the display. The system may further include an image data adjuster configured to adjust the image data corresponding to the at least one icon based on the display policy.

First claim

What is claimed:

1. An information handling system (IHS) comprising:
a display policy related to a display, wherein the display policy provides information concerning: (1) at least one icon for display on the display, and (2) a schedule for changing a size of the at least one icon over a period of time;
an image data storage configured to store image data corresponding to the at least one icon for the display; and
an image data adjuster configured to adjust the image data corresponding to the at least one icon based on the display policy, wherein the at least one icon comprises a plurality of red pixels, a plurality of green pixels, and a plurality of blue pixels, and wherein the IHS further comprising a pixel controller configured to: (1) provide a plurality of values corresponding to the plurality of red pixels to the display, (2) provide a plurality of values corresponding to the plurality of green pixels to the display, and (3) provide a plurality of values corresponding to the plurality of blue pixels to the display.

2. The IHS of claim 1 , wherein the image data adjuster is further configured to at least: (1) modify at least one of the plurality of values corresponding to the plurality of red pixels, (2) modify at least one of the plurality of values corresponding to the plurality of green pixels, or (3) modify at least one of the plurality of values corresponding to the plurality of blue pixels to adjust the image data based on the display policy.

3. The IHS of claim 1 , wherein the image data storage is further configured to provide text image data corresponding to at least one text element having a font size, and wherein the image data adjuster is configured to adjust the font size of the at least one text element based on the display policy.

4. The IHS of claim 1 , wherein the display is an organic light emitting display (OLED), and wherein the image data adjuster is configured to modify at least one of the plurality of values corresponding to only the plurality of blue pixels to adjust the image data based on the display policy.

5. The IHS of claim 1 , wherein the schedule for changing the size of the at least one icon over a period of time comprises automatically: (1) changing the size of the at least one icon to a smaller size from an original size after an elapse of at least a first portion of the period of time, (2) maintaining the size of the at least one icon at the smaller size for at least a second portion of the period of time, and (3) changing the size of the at least one icon to the original size after an elapse of the second portion of the period of time.

6. An information handling system (IHS) comprising:
a display policy related to a display, wherein the display policy provides information concerning at least one contextual metric related to the display;
a context detector configured to detect at least one value corresponding to the at least one contextual metric related to the display;
an image data storage configured to store image data for the display; and
an image data adjuster configured to adjust the image data based on the at least one value corresponding to the at least one contextual metric related to the display, wherein the image data comprises: (1) a plurality of values corresponding to the plurality of red pixels to the display, (2) provide a plurality of values corresponding to the plurality of green pixels to the display, and (3) provide a plurality of values corresponding to the plurality of blue pixels to the display, and wherein the image data adjuster is further configured to at least: (1) modify at least one of the plurality of values corresponding to the plurality of red pixels, (2) modify at least one of the plurality of values corresponding to the plurality of green pixels, or (3) modify at least one of the plurality of values corresponding to the plurality of blue pixels to adjust the image data based on the at least one value corresponding to the at least one contextual metric related to the display.

7. The IHS of claim 6 , wherein the contextual metric relates to at least one of a user type or a usage pattern associated with the display.

8. The IHS of claim 7 , wherein the context detector is configured to detect the user type based at least on login information associated with a user.

9. The IHS of claim 7 , wherein the context detector is configured to detect the usage pattern based at least on a pattern of use of a type of software by a user.

10. The IHS of claim 6 , wherein the image data adjuster is further configured to modify at least one of the plurality of values corresponding to only the plurality of blue pixels to adjust the image data based on the at least one value corresponding to the at least one contextual metric related to the display.

11. The IHS of claim 6 , wherein the display is an organic light emitting display (OLED), and wherein the image data adjuster is configured to modify at least one of a plurality of values corresponding to only a plurality of blue pixels to adjust the image data based on the display policy.

12. An information handling system (IHS) comprising:
a first display;
a second display;
a display policy related to the first display or the second display, wherein the display policy provides information concerning use of the first display and the second display;
a detector configured to generate usage data concerning use of the first display and use of the second display; and
a controller configured to change at least one parameter associated with at least one of the first display or the second display based on both the display policy and the usage data.

13. The IHS of claim 12 , wherein the detector comprises a presence detector to detect a presence of a user in a vicinity of the at least the first display or the second display.

14. The IHS of claim 12 , wherein the at least one parameter associated with the at least one of the first display or the second display includes at least one of a brightness, contrast, or another parameter related to an image displayed on the first display or the second display.

15. The IHS of claim 12 , wherein the controller is further configured to switch an image being displayed from the first display to the second display based on the display policy.

16. The IHS of claim 12 , wherein each of the at least the first display or the second display is configured to display a plurality of windows corresponding to a plurality of applications, and wherein the controller is further configured to detect an active window from among the plurality of windows, and wherein the controller is further configured to change at least one display parameter associated with the active window relative to at least one of a remaining set of the plurality of windows.

17. The IHS of claim 12 , wherein the display policy further includes information concerning: (1) at least one icon for display on the at least the first display or the second display, and (2) a schedule for changing a size of the at least one icon over a period of time, further comprising:
an image data storage configured to provide image data corresponding to the at least one icon to the at least the first display or the second display; and
an image data adjuster configured to, before providing the image data corresponding to the at least one icon to the at least the first display or the second display, adjust the image data based on the display policy.

18. The IHS of claim 12 , wherein the display policy further includes information concerning at least one contextual metric related to the at least th
