LED lighting has largely replaced traditional incandescent bulbs and energy-saving lamps because it is more efficient and long-lasting. Meanwhile, another variant has become popular in retail. Its abbreviation: OLED. What is behind it, and is it worth switching at home?
OLED stands for “organic light-emitting diode.” The difference from traditional LEDs lies in the material and the form of the light. Conventional LEDs produce a lot of light in a tiny area, which can quickly cause glare. An OLED consists of several ultra-thin layers between two electrodes. When electricity flows through, the entire surface lights up evenly. The result is a soft, diffuse light with excellent color rendering.

Beginnings in Monitor and TV Technology
Many are already familiar with the name OLED. The technology is well-established in high-end TVs and many current smartphones, where it already showcases one of its advantages. Since each pixel can be completely turned off, it creates a deep black and thus a very high contrast.
However, OLED is also interesting for lighting. Instead of many individual light points working together, OLED creates a continuously illuminated surface, which is also more pleasant for the eyes.

Lighting Still in Development
Currently, OLED is still far from becoming the next standard in lighting. Dennis Ellenberger, a hardware expert at Computerbild, explains: “With OLED, high contrasts, individually lit pixels, and extremely thin displays are important. These features hardly matter for lamps or ceiling lights, so I don’t believe this area will become more established.”
Ready-made light sources for replacing bulbs are also hard to find. So far, there are only initial finished lamps and experiments. Designers and industry are already experimenting with the new technology because it offers new design options. OLED panels are thin, flat, and often flexible. They can thus “disappear” directly into furniture, walls, or ceilings.
The OLED technology is already much more widespread in the automotive industry. Here, manufacturers are already using OLED for taillights because the light is evenly distributed.
But where could opportunities for OLED technology lie? Dennis Ellenberger adds: “OLED displays, on the other hand, can be well integrated into kitchen appliances, washing machines, dryers, furniture (such as mirrors with integrated OLED displays), windows, and glass surfaces (transparent OLEDs as info displays), and digital picture frames.” Because they are extremely thin, flexible, self-illuminating, and require no backlighting, he sees a lot of potential in their development.

Are OLEDs More Efficient Than LED Lights?
Regarding energy-saving potential and light output, current headlines about OLED should be taken with caution. Modern LEDs deliver up to 150 lumens (a unit of brightness for a light) per watt. The OLEDs currently available still achieve only half of this light output. In other words, the new technology requires more electricity for the same brightness.
It would be different if OLEDs were significantly more durable than LEDs. But here, too, the new technology lags behind. Since the light sources are also more complex to manufacture and no comparably high quantities are produced yet, OLEDs fall short in terms of efficiency, lifespan, and acquisition costs compared to the proven LED technology. This could, of course, change in the coming years. However, those looking to purchase OLEDs to save more energy may be disappointed.
OLED already surpasses LED today when it comes to design freedom for designers. The thin and flexible construction will bring forth new light fixtures. The new technology also scores in terms of color rendering, seamless dimming, and the free choice of light color. It remains interesting to follow further developments.
