摘要： The invention relates to an organic light-emitting diode (OLED) system comprising a multi-layered structure having at least two reflective interfaces, and a semiconducting organic layer sandwiched between first and second electrodes; wherein at least one of the reflective interfaces is semi-transparent to form a microcavity in between the two reflective interfaces; wherein a layer is provided in the microcavity between an electrode and a reflective interface that is formed of a photoactive birefringent material; and wherein the photoactive birefringent material is selectively activated.
