- Substantial multi-billion OLED displays market with Samsung, LG, Sony, and

others producing – mainly for portable consumer electronics (mobile phones,

MP3 player, OLED tablets), but also OLED TVs

- OLED Lighting market far behind –

mainly R&D and premium price lighting

panels ($500/unit and more)

- World-wide lighting market ~$75bn

High price! Cheapest panels cost $500

Cost is coming down – approx. $1,000 to $1500 /klm

lamp today from $2,500 a year ago (equivalent

of a 60W lamp!). Gen 5 line expected to offer

$50-$100 price range. – LED is $5 /klm today!

Only small quantities

Pilot lines, production still difficult

Achieved efficiency is behind theory,

LED vs OLED Lighting


Basic OLED Structure:

- Substrate

- Backplane

- Organic layers

- Barrier/Encapsulation

⬇ High cost in display-quality

glass which needs to be

reduced in price (watch

Samsung/Corning venture)

⬇ Edge seal is a challenge

Lifetime in hours


OLED device

Theoretically very efficient – up to 150 lm/V

Green – No toxic materials, easy to dispose of and recycle

Natural looking light temperature

Freedom of design (surface emitted light)

Can be transparent – first ones to reach the market in 2013

Can be flexible – not clear when, but work in progess (GE with Konica Minolta, Philips, LG OLED, AUO, Bayer, Visionox etc)

Trade-off between colour saturation, lifetime and efficiency

High price

burn-in effect

Different lifetime of the different colours – blue is far behind

PROS

CONS


• Technically, they offer little advantage over LEDs, except flexibility, thickness and lower

temperature operation.

• LED lighting is a large and rapidly growing industry. The technology is proven and

scaleable. They are beginning to be flexible etc. They fit in standard light sockets and

are cheap (and getting cheaper).

• Many companies are involved in OLED lighting – is it just because they cannot compete

in OLED displays?

Does OLED Lighting have a future?

Investment for larger area device manufacturing to lower cost

Material cost reduction (glass, edge barriers etc)

Yield improvement

Availability and cost of flexible barriers

Differentiated product design and marketing from LED lighting

Lighting

key

challenges


Despite the initial narrow performance gap between OLED and LCD displays, OLED displays succeeded because they offered a way for Samsung to differentiate their cellphone versus the competition.

So too may OLED lighting succeed – not necessarily because they offer a technical improvement over LEDs but if the backers can design new lighting designs not easily replicated with LEDs and market it as better.

Will OLED lighting succeed?
