Abstract:
(EN) A top emission organic light emitting diode (OLED), and manufacturing method. The top emission OLED comprises: a substrate (11); a stack structure (12) provided on the substrate (11); a cathode layer (13) covering the stack structure (12); a light scattering layer (14) formed by nanoparticles and having a protrusion- and indentation-containing structure. In this way, the present invention effectively improves a cathode transmittance of a top emission OLED, and enables modulation of a coupled output of light having multiple wavelengths.
(FR) L'invention concerne une diode électroluminescente organique à émission par le haut (OLED) et un procédé de fabrication. L'OLED à émission par le haut comprend : un substrat (11); une structure d'empilement (12) disposée sur le substrat (11); une couche de cathode (13) recouvrant la structure d'empilement (12); une couche de diffusion de lumière (14) formée par des nanoparticules et ayant une structure contenant des saillies et des indentations. De cette manière, la présente invention améliore efficacement une transmittance de cathode d'une OLED à émission par le haut, et permet la modulation d'une sortie couplée de lumière ayant de multiples longueurs d'onde.
(ZH) 一种顶发射有机发光二极管及制造方法,顶发射有机发光二极管包括:衬底基板(11);层叠结构(12),层叠结构(12)设置于衬底基板(11)上;阴极层(13),阴极层(13)覆盖层叠结构(12);光散射层(14),光散射层(14)由纳米颗粒组成,且光散射层(14)具有凹凸结构。通过上述方式,能够有效提高顶发射有机发光二极管阴极透射率,调制多波长光的耦合输出。
