1. A method for optimizing lifetime of an OLED display element, the OLED display element comprising a plurality of addressable discrete OLED pixels, each of said OLED pixels being driven by a supply voltage and a drive current provided by a current driver, each OLED pixel having a threshold voltage, the method comprising, for an OLED pixel:

  • determining an environmental parameter which affects aging of an OLED pixel, determining a first operational parameter indicative of aging of the OLED pixel, and compensating at least partly for aging by changing a second operating parameter of the OLED pixel based on the determination of the environmental parameter and the first operational parameter.
