LED Research for Displays and Lighting
We support the research and development of Organic LEDs and Perovskite LEDs. With our software, you can design your LEDs and have a better understanding of the physics of the device. Our instruments allow you to perform electrical and optical characterizations of LEDs. The device stability can be estimated with a patented LED accelerated aging and lifetime procedure.
Simulation and Design of LEDs
Optimize the OLED Light Emission
Use Setfos Emission to simulate the device color, angular distribution, efficacy (and more!)
Use Setfos Advanced Optics to optimize layer stacks with scattering elements, such as quantum dots, scattering particles, scattering surfaces, or birefringent materials.
Model Charge Transport in OLEDs
Use Setfos Drift-Diffusion to simulate the current-voltage (IV) characteristics, transient signals, and results obtained by impedance spectroscopy.
In combination with Paios and Phelos, the simulation gets even more powerful by fitting automatically the experimental results.
Simulate OLED Upscaling
Going from a millimeter-scale OLED to a large-scale device for lighting is a big challenge.
Use Laoss to optimize metal grids to enhance conductivity, mastering electro-thermal effects, or to couple the OLED with complex optical elements or surface structuring.

Optical and Electrical Characterization of LEDs
AC, DC and Transient Opto-Electrical Characterization
Paios performs a variety of electrical and optical characterizations. You can determine the charge carrier mobility, trap density and distribution, recombination, injection barriers, doping-densities, series resistance, capacitance, and other working parameters of an OLED.
Angular Dependent Electro- and Photo-Luminescence
Phelos measures the electroluminescence (EL) of an OLED over a range of emission and polarization angles. The photoluminescence (PL) signal of a given light-emitting material can be also collected. You can also determine the position and orientation of the dipoles in the emission layer.
Accelerated Lifetime Analyis with Parallel Channels
Litos is the primary choice to understand the degradation behavior of organic, perovskite, and quantum-dots LEDs, thanks to the wide range of stressing techniques inside a highly-controlled experimental environment, full automation, and the possibility to be interfaced with Paios.
