Patent ID: 10084155

Abstract:
The OLED display of the invention comprises a TFE layer, comprising: inorganic passivation layers, organic buffer layers and a moisture/oxygen quenching layer (MOQL), wherein the inorganic passivation layers and the organic buffer layers form a stacked structure, and the MOQL comprises a first MOQL located between the stack structure and OLED layer, or a second MOQL located between the two inorganic passivation layers, or a combination of two. In TFE layer, the MOQL can effectively prevent, through physisorption or chemical reaction, the damage of the OLED device caused by moisture/oxygen without affecting the luminescence performance of the OLED device so as to enhance the OLED device lifespan, and release the stress of inorganic passivation layers in TFE layer, reduce the number of layers and thickness of the TFE layer, thereby reduce the thickness of the OLED display and improve the flexibility of flexible OLED display.
