Simulation Paves the Way for More Efficient OLED Devices

Caty Fairclough | April 7, 2016

When it comes to creating the next generation of flat panel displays and solid-state area lighting, organic light-emitting diodes, or OLEDs, may be used to help. While recognized for its various advantages, this emerging technology suffers from some weaknesses that reduce its overall efficiency. One such example is light loss, which is partially caused by the plasmon coupling effect. Looking to reduce the effect’s prominence in OLED devices, researchers from Konica Minolta Laboratory turned to the COMSOL Multiphysics® software.

Physicist and electrical engineer Dennis Gabor invented holography about 70 years ago. Ever since then, the form of optical technology has developed in many different ways. In this blog post, part one in a series, we talk about a specific industrial application of holograms in consumer electronics and demonstrate how to use COMSOL Multiphysics to simulate holograms in a wide spectrum of optical and numerical techniques.

Whenever you are modeling coils with the AC/DC Module in COMSOL Multiphysics, you need to consider what type of boundary conditions to use to truncate your modeling domain. In this blog post, we will introduce the different boundary conditions that you can use and how to choose between them.

One of the most common uses of the AC/DC Module is for modeling electromagnetic coils and the interactions with their surroundings. Today, we will look into one of the key concepts to keep in mind when modeling coils: closing the current loop. If your work involves modeling coils, you will need a complete understanding of this topic.

Touchscreen technology is becoming more and more common in consumer electronics. When designing these interfaces, achieving accuracy, as well as a fast time-to-market, is key. Using our Touchscreen Simulator demo app, we show you how simulation apps can aid in the design of capacitive touchscreen devices.

Piezoelectricity finds use in a variety of engineering applications. They include transducers, inkjet printheads, adaptive optics, switching devices, cellphone components, and guitar pickups, to name a few. Today’s blog post will benefit both beginners and experts in piezoelectricity, as we highlight some of the fundamental elements of piezoelectric theory and basic simulations, along with a novel design for improving the range of motion for piezoelectric actuators.

Characterizing magnetic behavior is crucial when designing magnetic devices involving ferromagnetic materials. Different materials (or the same material after certain processes) can react differently to the same stimulus and improper characterization can cause device failure. COMSOL Multiphysics® software version 5.2 expands the current support for describing magnetic materials and defines access to material models through external routines. Here, we demonstrate how this new functionality works in a case featuring hysteresis and review the current opportunities for modeling ferromagnetic materials.

If you’ve ever worked with the Terminal boundary condition in COMSOL Multiphysics, you know that this electrical boundary condition can apply a current or voltage, among other options. But did you know that you can also dynamically switch between excitation types during a transient simulation? This is useful if you are trying to model a current- or voltage-limited power supply, for example. Today, we will look at how to implement such a switching behavior.

In a previous blog entry, we showed you how to model rotating machines, like motors and generators, using the Rotating Machinery, Magnetic interface in COMSOL Multiphysics. Today, we will demonstrate the steps we outlined with a 3D generator model example, comparing our results with an analogous 2D model. The concepts of sector symmetry and periodic boundary conditions, including examples illustrating their use, are also highlighted.

Today, guest blogger and Certified Consultant Nagi Elabbasi of Veryst Engineering shares simulation research designed to optimize band gaps for phononic crystals. Phononic crystals are rather unique materials that can be engineered with a particular band gap. As the demand for these materials continues to grow, so does the interest in simulating them, specifically to optimize their band gaps. COMSOL Multiphysics, as we’ll show you here, can be used to perform such studies.
