有机发光二极管显示器
摘要：
有机发光二极管(OLED)显示器包括：第一电极；在所述第一电极上形成的空穴辅助层；在所述空穴辅助层上形成的红色有机发射层、绿色有机发射层和蓝色有机发射层；分别位于在所述空穴辅助层与所述红色有机发射层之间以及所述空穴辅助层与所述绿色有机发射层之间的红色辅助层和绿色辅助层；在所述红色有机发射层、所述绿色有机发射层和所述蓝色有机发射层上形成的电子辅助层；以及在所述电子辅助层上形成的第二电极。所述红色辅助层和所述绿色辅助层中至少之一包括电荷速率控制层，并且所述电荷速率控制层的T1能级相对高于所述有机发射层的T1能级。
摘要（英）：

An organic light emitting diode (OLED) display includes: a first electrode; a hole auxiliary layer formed on the first electrode; a red organic emitting layer, a green organic emitting layer, and a blue organic emitting layer formed on the hole auxiliary layer; a red auxiliary layer and a green auxiliary layer located between the hole auxiliary layer and the red organic emitting layer and between the hole auxiliary layer and the green organic emitting layer, respectively; an electron auxiliary layer formed on the red organic emitting layer, the green organic emitting layer, and the blue organic emitting layer; and a second electrode formed on the electron auxiliary layer. At least one of the red auxiliary layer and the green auxiliary layer includes a charge speed control layer, and a T1 level of the charge speed control layer is relatively higher than that of the organic emitting layer.
