一种有机发光显示面板以及制作方法
摘要：
本发明实施例公开了一种有机发光显示面板以及制作方法，所述方法包括：形成在基板上的多种不同发光颜色的像素区域；每一所述像素区域包括远离所述基板方向设置的第一电极、第一辅助发光层、发光材料层、第二辅助发光层以及第二电极；所述第二辅助发光层至少包含第一子辅助发光层；所述第一电极和所述第二电极之间形成微腔结构；至少一种发光颜色的所述第二辅助发光层还包含有第二子辅助发光层；所述第一子辅助发光层和/或所述第二子辅助发光层的形成材料至少包括第一电子型材料；所述第二子辅助发光层的电子零场迁移率大于或等于1.0×10‑4cm2/V·S。通过本发明的技术方案，解决了电荷和空穴在发光材料层的失衡现象，实现了OLED器件优异的光输出效率和增强的寿命。
摘要（英）：

The present disclosure provides an OLED display panel, including a substrate and a plurality of pixel regions disposed on the substrate and emitting light in different colors. A pixel region includes a first electrode, a first auxiliary light-emitting layer, a light-emitting layer, a second auxiliary light-emitting layer, and a second electrode. A micro-cavity structure is formed between the first electrode and the second electrode. The second auxiliary light-emitting layer includes at least a first sub-auxiliary light-emitting layer. The second auxiliary light-emitting layer corresponding to the pixel regions emitting light in at least one color also includes a second sub-auxiliary light-emitting layer. At least one of the first sub-auxiliary light-emitting layer and the second sub-auxiliary light-emitting layer is made of at least a first electron-type material. The second sub-auxiliary light-emitting layer has a zero-field electron mobility greater than or equal to a pre-determined threshold.
