1. A method of translating parameters extracted from a pixel circuit to parameters for compensating said pixel circuit, said pixel circuit including a light emitting device, a drive device to provide a programmable drive current to the light emitting device, a programming input, a storage device to store a programming signal, the method comprising:

  • extracting a given set of parameters for a pixel model based on measurement cycle conditions from a set of measurements,calculating outputs of the pixel circuit for a set of given inputs based on a pixel model for a driving (emission) cycle using the extracted parameters,using said calculated outputs and a model to extract a new set of parameters, andusing the new set of parameters to compensate the pixel circuit during a driving (emission) cycle.
