Abstract

This work proposes a new electrical model and design of ultra-fast μ-OLED devices under ON-OFF electrical pulse regime. The new model is an equivalent electrical model capable of accounting for large amplitude excitation as well as ultra-short pulse response. Moreover, coplanar wave-guided electrodes are proposed, for the first time, to maximize pulse energy delivery to the organic hetero-structure and to minimize the μ-OLED time response. An analytical expression of the time response is derived from the model which reveals the design key parameters. Moreover, preliminary experimental results presented in this work demonstrate state-of-the-art OLED current density of 2 kA/cm² and better than state-of-the-art optical pulse duration as short as 10 ns in the range of the radiative lifetime of singlet excitons.
