LED vs. OLED

LED� Point light source� High peak luminance� High efficacy� Long lifetime� Price decrease

OLED� Areal light source� Low homogenous luminance� High efficacy (future)� Short lifetime� Expensive

Organic light emitting diode (OLED)A new lightsource for general illumination

OLED – Areal light source

� Extremely thin light source

� Generates homogenous, non-glaring surfaces

� High color rendition

� Low thermal impact

� Low environmental impact (only minimum substances needed)

� Will enable new, innovative luminaires(thin, color changing, transparent, bent or flexible)

Organic light emitting diode (OLED)Key parameters: Actuals and forecast

Status and forecast

� Actual efficacies are around 40 lm/W, expected increase up to 100 lm/W forecasted till 2015

� Actual lifetimes approx. 10.000 h; forecasted to reach 50.000 h in 2015

� Transparent OLEDs to be introduced this year, bent OLEDsexpected till 2014; flexible OLEDs will follow later

� OLEDs are still very expensive, but a price reduction of factor 100 is forecasted till 2014 !

Application areas

� With key performance criterias as listed above, OLEDs are still restricted to high end decorative (semi-professional) lighting; usagein real professional lighting will start 2014

� But finally the OLED technology will enable new applications, newform factors, new luminaires in professional lighting
