摘要： In one aspect of the invention, an organic light emitting diode device has a substrate, a cathode formed on the substrate, an anode spaced-apart from the cathode, a plurality of electroluminescent units stacked between the cathode and the anode, and a plurality of charge generation layers, each of which is formed between two adjacent electroluminescent units. Each electroluminescent unit has an electron-transport layer, an emission layer formed on the electron-transport layer, and a hole-transport layer formed on the emission layer. The electron-transport layer of the first electroluminescent unit is formed on the cathode, defining a first energy barrier, and the anode is formed on the hole-transport layer of the last electroluminescent unit, defining a second energy barrier. The first energy barrier is higher than the second energy barrier. The first electroluminescent unit has a lifetime longer than that of each of the rest electroluminescent units.

摘要： An illumination device including a substrate, a first conductive layer, a second conductive layer, a self-illuminating layer, and a first auxiliary conductive pattern layer is provided. The first conductive layer and the second conductive layer are disposed on the substrate. The self-illuminating layer is located between the first conductive layer and the second conductive layer to define an illumination region on the substrate. The first auxiliary conductive pattern layer is in contact with the first conductive layer and has an impedance smaller than that of the first conductive layer. A ratio of a perimeter (um) of the first auxiliary conductive pattern layer occupied in the illumination region to an area (um2) of the illumination region is greater than about 0 and smaller than or equal to about 0.0262 (1/um).
