摘要： A method for controlling and compensating aging in an LED device includes measuring a performance change in light output of the LED device. The LED device is controlled with a first compensation algorithm derived from the measured performance change, during a first period, to effect a luminance change over time in the light output of the LED device. Subsequently, a second compensation algorithm, derived from the measured performance change, and different from the first compensation algorithm, during a second period, effects a second luminance change over time in the LED device's light output. The second luminance change over time in the second period is different from the first luminance change over time in the first period. Furthermore, the first and second periods together are less than the lifetime of the LED device.

摘要： A white light-emitting microcavity light-emitting diode device, includes a reflective electrode (12) and a semi-transparent electrode (16) formed over a substrate and an unpatterned white-light-emitting layer (14) formed between the reflective electrode and the semi-transparent electrode, the reflective electrode, semi-transparent electrode, and unpatterned white-light-emitting layer forming an optical cavity. The reflective or semi-transparent electrode is patterned to form independently-controllable light-emitting sub-pixel elements (50, 52, 54, 56). Color filters (40R, 40G, 40B) are formed over a side of the semi-transparent electrodes opposite the unpatterned white light-emitting-layer in correspondence with the light-emitting elements to form colored sub-pixels. At least one light-emitting element has at least two commonly-controlled portions (56Y, 56B) to emit white light to form a white sub-pixel. The white sub-pixel includes optical microcavities (66Y, 66B) tuned to emit light at a different complementary wavelength at an emission angle.
