Mass Production Technology of Flexible AMOLED Displays and Improvement of the OLED Device Characteristics

Abstract

We have developed low power consumption 6.18″ WQHD+ flexible AMOLED display with highly efficient top-emission type Blue OLED and successfully launched its mass production. For the next step, we develop more reliable flexible AMOLED display composed by a hole transport material with deep HOMO level and high hole injection property, and a hole-blocking material with shallow LUMO level and strong electron braking ability.
