有机发光器件和具有该有机发光器件的有机发光显示器
摘要：
公开了一种有机发光器件和具有该有机发光器件的有机发光显示器。该有机发光器件包括：第一电极，其分别连接到形成在基板上的薄膜晶体管；第二电极，其与第一电极相对；以及有机叠层，其形成在第一电极与第二电极之间，并且包括空穴传输层、多层发光结构和电子传输层。该多层发光结构包括：两个或更多个发光层，其通过经由第一电极和第二电极注入的电子和空穴的复合而发射不同颜色的光；以及电荷传输控制层，其由双极材料形成，位于所述两个或更多个发光层之间的边界处，电荷传输控制层传输电子和空穴两者，并且控制在所述两个或更多个发光层之间传输的电荷的量。
摘要（英）：

An organic light emitting device including a first electrode connected to a thin film transistor formed on a substrate, a second electrode opposite to the first electrode, and an organic laminate formed between the first electrode and the second electrode and including a hole transport layer, a multilayer-light emitting structure, and an electron transport layer. The multilayer-light emitting structure includes at least two light emitting layers emitting light of different colors through recombination of electrons and holes injected through the first and second electrodes, and a charge transport control layer formed of a bipolar material transporting both electrons and holes at boundaries between the at least two light emitting layers and controlling the amount of charges transported between the at least two light emitting layers.
