From smartphones to TVs and smartwatches, the development of new device architectures and material systems extends the lifetime and optimizes the energy consumption of our everyday OLED devices, contributing to a more sustainable display world.
Our solutions
Our material prolongs the device's lifetime by optimizing its architecture and the intrinsic stability of its molecules.
We are developing new and innovative hole transport materials (HTMs), which are essential elements for the evolution of OLED. HTMs play a crucial role in every OLED stack, maintaining the delicate balance of electrical charge across the pixel stack. By improving HTMs, we increase both the efficiency and lifespan of OLED screens, making the technology more reliable and sustainable.
New class of host and deuteration
In addition to our innovative HTM technology, two other solutions can be applied to prolong the device's lifetime: optimized host material for the emitter and the deuteration of the host.
Optimized host systems can offer a significantly longer lifetime (LT). There is no one-fits-all host – we are matching our host system with the applied emitter.
Increase in device lifetime by deuteration of the e-host or h-host of a typical host system, which increases the intrinsic stability of the molecule.
