Abstract
An arrangement for maintaining even tube burn-in. The arrangement identifies active and inactive display regions on a display unit when video content is displayed on the display unit. When inactive display regions are identified the arrangement monitors the duration that the active display regions remain active. After the active display regions become inactive and a predetermined time period has passed the arrangement displays a corrective image on the identified inactive regions. The predetermined time period may be set by a user or based on the user's viewing habits.
Claims19
A method for equalizing burn-in in a display unit having a plurality of display elements, the method comprising the steps of:
- identifying active display elements and non-active display elements on the display unit when video content is displayed on the display unit;
- monitoring an aging of the active display elements;
- and
- displaying a corrective image on the identified non-active display elements starting at a time that matches a starting time manually selected by a user;
- turning off the displayed corrective image if an aging of the identified non-active display elements matches the aging of the active display elements;
- and
- turning off the displayed corrective image at a time that matches an ending time manually selected by a user if the aging of the identified non-active display elements does not match the aging of the active display elements.
A system for equalizing a display regions of a display, the system comprising:
- means for identifying active display elements and non-active display elements on the display unit when video content is displayed on the display unit;
- means for monitoring an aging of the active display elements;
- means for displaying a corrective image on the identified non-active display elements at a time that matches a starting time manually selected by a user;
- means for turning off the displayed corrective image if an aging of the identified non-active display elements matches the aging of the active display elements;
- and
- means for turning off the displayed corrective image at a time that matches an ending time manually selected by a user if the aging of the identified non-active display elements does not match the aging of the active display elements.

- and
- removing the corrective image on the identified non-active display elements if an aging of the identified non-active display elements matches the aging of the active display elements before an ending time that matches an ending time manually selected by a user.
