OLED Research for Display and Lighting
Fluxim provides tools for research and development of OLEDs for the display and lighting market. Our customers in industry and at universities use our simulation and measurement tools to understand device physics and optimize OLED structure and material.
Optimize OLED Light Emission
The Setfos Emission module is a simulation software that calculates optical interference in thin-film layers. It considers optical interference and guided modes and is applied to calculate light emission from OLED. Thereby colour, angular distribution, efficiacy and further parameters can be studied and optimized.
Use the Setfos Light Scattering module to optimize layer stacks with scattering structures frequently applied in OLED lighting.
Simulate Charge Transport in OLEDs with Drift-Diffusion
The software Setfos simulates charge transport in OLED. It allows the fine-tuning of the layer stack and thicknesses and to gain understanding of the underlying physical processes.
Setfos simulates IV-curves, transient signals and also impedance spectroscopy (small signal analysis). In combination with our measurement system (see below) the simulation software gets even more powerful by fitting automatically to measured results.
Characterization of OLED Emission versus Angle
Phelos is a characterization tool that measures the emission spectrum of OLED and other devices over varied angles. Both s-polarized and p-polarized light is measured.
In combination with the Setfos emission module the emission-zone can be calculated. This means you can find out where in your emission layer the dipoles emit light and what orientation the dipoles have.
Opto-Electrical Characterization of OLEDs
The measurement system Paios performs a variety of experimental techniques on OLED. All techniques are automatically measured with one click leading to highly systematic results.
Paios is applied to study charge carrier mobilities, traps, recombination, injection barriers, doping-densities, series resistance, capacitance and other parameters of OLED layers.
Experimental techquies include IVL-curves, transient eletroluminescence (TEL), CELIV, impedance spectroscopy, capacitance-voltage and others.
Simulate the Upscaling of OLEDs
Going from small millimeter-scale OLED to large scales for displays or lighting is a huge challenge. Lateral current flow leads to a voltage drop due to ohmic losses.
Use the simulation software Laoss to simulate large area OLED and optimize metal grids to enhance conductivity.
