Lighting market overview High volume / cost sensitive / multiple segments

– General lighting (illumination) – General lighting (luminance) – Automotive lighting – Special lighting

Lifetime – Use life (general) ~ 10 kh

• To 80% initial brightness (LT80) • B3 (time to 3% devices failed)

– Shelf life (general) ~ 10 years

Efficacy – Depends on market segment – Minimal 30 lm/W

Color – CRI > 80 for illumination – All colors for luminance

Key differentiators

• Thin • Reflective • High-tech impression (innovators / early

adopters)

• Light weight • flat • freedom in 2D • all colors • high quality light • diffuse light • dimmable

IMOLA Workshop, Barcelona, 6 May 2014 14

OLEDs are thin

Unlike all other light sources, OLEDs are flat and directly emit light over the complete surface. The effect is a large area of homogenous light.
