System and methods for extracting correlation curves for an organic light emitting device

A display system configured for compensating of aging effects, comprising:

• a plurality of pixels configured to display images, each said pixel comprising an organic light emitting diode (OLED);
• a memory configured to store characterization data for a pixel stress condition;
• and
• a controller coupled to the plurality of pixels, the controller configured to determine a stress condition on a pixel of the plurality of pixels, and to determine a compensation factor for a programming based on the characterization data.

A method for compensating of aging effects in a display system comprising a plurality of organic light emitting diode (OLED) based pixels configured to display images, the method comprising:

• performing measurements on a reference device under a reference stress condition to obtain characterization data, wherein the reference device is not part of the plurality of OLED based pixels configured to display images;
• determining a stress condition on a pixel of the OLED pixels resulting from displaying images during operation of the display system,
• determining a compensation factor to apply to a programming of the pixel based on the characterization data, and
• adjusting the programming of the pixel based on the compensation factor.
