Abstract
A system and method are disclosed for determining a pixel capacitance. The pixel capacitance is correlated to a pixel age to determine a current correction factor used for compensating the pixel drive current to account for luminance degradation of the pixel that results from the pixel aging.

38. A control block for compensating for luminance degradation of a pixel having an electroluminescent device, the control block being configured to:
-
determine a capacitance of the electroluminescent device; correlate the determined capacitance of the electroluminescent device to a current correction factor for the electroluminescent device; compensate a drive current for the electroluminescent device according to the correlated current correction factor; and drive the electroluminescent device with the compensated drive current.
