Organic Light Emitting Diode - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240206330 titled 'Organic Light Emitting Diode
The present disclosure pertains to an organic light emitting diode (OLED) with adjacent emitting material layers containing hosts with different lumo energy levels and/or electron mobility. A first emitting material layer with a host having slow electron mobility and/or high lumo energy level is placed next to a hole transport layer, while a second emitting material layer with a host having fast electron mobility and/or low lumo energy level is positioned adjacent to an electron transport layer. By preventing exciplex formation between the hole transporting material and the first host, and promoting exciplex formation between the hole transporting material and the second host, the OLED can minimize exciton loss, resulting in low driving voltage, low power consumption, and improved luminous properties and lifetime.

Original Abstract Submitted
the present disclosure relates to an organic light emitting diode (oled) where adjacent emitting material layers includes hosts with different lumo energy level and/or electron mobility. a first emitting material layer including a first host with relatively slow electron mobility and/or relatively high lumo energy level is disposed adjacently to a hole transport layer and a second emitting material layer including a second host with relatively fast electron mobility and/or relatively low lumo energy level is disposed adjacent to an electron transport layer. no exciplex between hole transporting material and the first host is not formed while exciplex between the hole transporting material and the second host is formed so that exciton loss can be minimized. an oled and an organic light emitting device with low driving voltage and low power consumption and beneficial luminous property and luminous lifetime can be realized.
