A Comparison of OLED and LED
7 February, 2013
Agenda
• OLED Film (4:20)
• Fundamentals of LEDs and OLEDs
• Application Examples
5
7 February, 2013 6
• First light which is a complete surface light. No optical system
needed to spread the light.
• No significant temperature rise.
• Can be transparent. Built on glass substrates. Organic layers
are so thin (100-150nm), that they are transparent.
• Aim: Larger, brighter, more efficient
• Aim: Reduce cost. Now 6000-7000 €/m2
• Sensitive to moisture and oxygen. Promise of “paint-on” light
and flexible OLEDs will require solution. Presently,
hermetically sealed packaging is required.

homogenous light over
the complete surface

Expensive
Strong growth in the market
Decent share in market
More mature (already considerable
price dropping)
Organic material (C-based complex

OLED: 10,000 lumens/m2
LED: 100 lumens/W, 1-2 W/mm2 100,000,000 to 200,000,000
lumen/m2
LED Point source OLED Area source
LED yields 10,000-20,000 times “brighter” light than OLED.
LED requires 1/10,000 -1/20,000 of the OLED area.
To compete, OLED must be 1/10,000 -1/20,000 of the cost/area
of LED.

Transparency
Transparency in the off-state is perceived as a very attractive
product feature, because no other material can make glass
glow – without being visible in the off-state.
Transparent OLEDs will be available as of mid 2013.

Flexibility
The next thing we are working on, are flexible OLEDs.
Flexible OLED displays are already on the market,
but if it comes to small molecule OLEDs in lighting
applications,
it is still in a research phase.
OLEDs will be flexible in 5 years from now.
