摘　　要：为了提升印刷器件的性能,从印刷OLED显示像素制备的需求角度出发,采用喷墨打印工艺在像素坑中精准沉积含全氟化离子交联聚合物掺杂的空穴注入层PEDOT∶PSS∶PFI来提高空穴注入效率,而后在其上蒸镀其他功能层得到OLED像素阵列器件。与喷墨打印制备的PEDOT∶PSS空穴注入层器件对比发现,含全氟化离子交联聚合物掺杂空穴注入层的器件具有较好的发光均匀性,器件最大亮度达到4325 cd/m2,最大电流效率达到5.5 cd/A。研究结果为多层印刷OLED显示器件的制备积累经验。According to the requirement of improved performance in the preparation of printed OLED display pixels,the inkjet printing process was used to accurately deposit perfluorinated ionomer-doped hole injection layer material PEDOT∶PSS∶PFI in the pixel in order to improve the efficiency of hole injection.The other functional layers were then sequentially prepared by vacuum thermal evaporation to obtain OLED pixel array devices.Comparison with inkjet-printed PEDOT∶PSS hole-injection layer devices shows that the devices doped with perfluorinated ionopolymer hole-injection layer have better luminance uniformity,with a maximum luminance of 4325 cd/m2 and a maximum current efficiency of 5.5 cd/A.This result provides experience in the preparation of multilayer printed OLED devices.
