Tandem OLED simulation
Model multi-emission-unit white OLEDs — emission units stacked through charge-generation layers — and read each unit's individual outcoupling efficiency, not just the device total.
What is a tandem OLED?
A tandem (stacked) OLED places two or more emission units (EUs) on top of one another, connected by charge-generation layers (CGLs). This multiplies efficiency and lifetime and is the standard architecture for high-brightness white OLED displays and lighting. Because the EUs sit at different optical positions in the cavity, each one couples to the microcavity differently — so the device must be modeled unit by unit.
What Phazic computes for tandem OLEDs
- Per-EU OCE breakdown — each emission unit's individual outcoupling efficiency, tagged by its absolute layer position.
- 3-EU RGB tandem white OLED presets — BLUE-near-cathode vs BLUE-near-anode configurations.
- Fluorescent / hyperfluorescent host–dopant choices (e.g. ADN:DPAVBi, mCBP:DABNA-1).
- System OCE = Purcell-weighted sum across all emission units.
- Full dipole model — Purcell factor, dipole orientation, and 5-channel loss (air / substrate / waveguide / SPP / host).
- Bottom / top / transparent tandem variants on a numerically stable S-matrix engine.
