OLED displays deliver unparalleled color brilliance and high contrast for a richer viewing experience – as you can see and feel in today’s high-end TVs.
The probability that you carry an OLED display in your pocket is quite high, as ca. 40% of smartphone displays in 2023 were OLEDs. OLED’s ever-improving display performance, durability and lifetime are opening the door to exciting IT applications like top-notch tablets, notebooks and monitors. And stepping into a new car you will not only see many more displays, but also more and more OLED screens.
Our solutions
Our transport and host material systems perform in all brightness ranges, from low to high, meeting the key requirements for high contrast. Our materials enable the adoption of the new color standard BT 2020, providing an even better color gamut. Dark mode, in which the background appears in black and the text in white, is particularly suited for OLED panels: black pixels don't require any voltage.
At the same time, our development efforts towards the next generation OLED materials will benefit the lifetime, energy efficiency, and picture quality of future OLED displays.
The market dynamics are breathtaking, and the challenges in terms of performance and reliability are immense. But in a great team and in close collaboration with our customers and partners we will get it right – this is my experience and my credo.
Improved efficiency and lifetime
High brightness is still one of the main goals of current display development. Here are two examples:
The introduction of transport materials with a reduced refractive index (RI) significantly improves the outcoupling of light. The example in Figure 1 shows an efficiency improvement by reducing the refractive index of HTM1, without compromising other performance parameters.
We have developed a portfolio of electron transport materials that can be applied to various OLED stacks to deliver optimal performance for the intended application. Figure 2 depicts device performance with our portfolio materials and industry reference materials in terms of relative External Quantum Efficiency (EQE) and lifetime. Our materials outperform industry standards, whilst allowing to tune device performance over a wide range of lifetime and efficiency.
