An organic light-emitting diode (OLED) is made of a stack of organic semiconductor layers sandwiched between a transparent conducting anode and a reflective metal cathode. Under an external electric bias between the anode and the cathode, holes, or positive charges from the anode and electrons from the cathode are forced into the organic semiconductor layers to form excitons (tightly bound hole-electron pairs). The annihilation of an exciton releases its energy radiatively to emit light. This proposal is on developing highly energy efficient OLED technology for a range of applications ranging from flat-panel displays to eco-friendly solid-state lightings.

有机发光二极管（OLED）是由一堆有机半导体层夹在透明导电阳极和反射金属阴极之间制成的。在阳极和阴极之间的外部电偏压下，来自阳极的空穴或正电荷和来自阴极的电子被迫进入有机半导体层形成激子（紧密结合的空穴-电子对）。激子的湮灭以辐射的方式释放出它的能量来发光。该提案旨在开发高能效的OLED技术，用于从平板显示器到环保固态照明的一系列应用。
