Abstract
A method for controlling aging compensation in an OLED display having one or more light emitting elements includes the steps of periodically measuring the change in display output to calculate a correction signal; restricting the change in the correction signal at each period; and applying the correction signal to the OLED display to effect a correction in the display output.
Claims24
A method for controlling aging compensation in an OLED display having one or more light emitting elements comprising the steps of periodically measuring the change in display output to calculate a correction signal;
- comparing any change in the periodically calculated correction signal to a correction limit, and restricting the change in the correction signal at each period if the change in the correction signal exceeds the correction limit;
- and applying the correction signal to the OLED display to effect a correction in the display output.
