1. An active matrix display device (10) having a plurality of pixels (110), wherein the pixels (110) are grouped into pixel groups (R′

  • , G′

    , B′

    ), according to a dominant degradation mechanism common to the pixels in each pixel group, and circuitry is present to drive each pixel group (R′

    , G′

    , B′

    ) at a specific duty cycle (62;

    73;

    82), wherein at least two pixel groups (R′

    , G′

    , B′

    ) are assigned different duty cycles.
