Abstract
Disclosed is a double-sided organic light-emitting diode lighting panel. A semitransparent silver film layer is provided between a first light-emitting layer that emits blue light and a second light-emitting layer that emits yellow light. Double-sided light emission of the OLED lighting panel is realized by taking advantage of semi-transparence and reflection properties of the silver film layer. Such a structure is relatively simple, and manufacture costs and manufacture difficulties are reduced. The OLED lighting panel can be used for interior lighting or can be used in places having special needs, and thus application of a double-sided OLED lighting device is widened.
