ITO-free flexible hybrid white organic/inorganic light-emitting diodes using optimum color conversion quantum dot plates

초록

In this work, we propose that indium-tin-oxide (ITO)-free flexible hybrid white organic/inorganic light illuminated device application has a potential for next-generation flexible display. The process involves conventional blue planar organic light-emitting diodes as light source and quantum dot (QD) color conversion plate. Semitransparent anode electrode is used in light-emitting diodes, which has effective micro-cavity phenomenon, instead of ITO that is a conventional transparent conductive oxide of display area. QD color conversion plate is used according to the optimized QD size in color rendering, which has improved energy transfer property, by control of wavelength and QD thickness for proper realization of QD plates through reduced QD aggregation.
