Additive Color Mixing of Semi-Transparent Laminated Tandem Type Polymer Light-Emitting Diodes

Authors

Abstract

Polymer light-emitting diodes (PLEDs) are generally fabricated using the wet process. Although it is difficult to stack multiple layers by the wet process, it is compatible with the lamination process that can be used to fabricate multi-layer tandem type devices. We fabricate tandem type PLEDs composed of two transparent substrates using the lamination process. Stacked red and green PLEDs exhibit additive color mixed emission resulting in orange emission. By careful selection of materials, similar emission is observed from both substrates of the semi-transparent tandem PLEDs because the over-layer does not absorb the emission from the under-layer.
