Consumer demand for ever brighter, more colorful, and energy-efficient displays continue to drive innovation in display materials. Quantum Dots, Phosphors, and OLEDs are increasingly working together to meet these demands, bringing incredible new display experiences to consumers, and changing the way we see our digital world.
Nanosys has a unique perspective on the latest developments across all three light emitting technologies as the company integrates its quantum dot technology into displays of all types including LCDs, miniLED LCDs, OLEDs, microLEDs and next generation nanoLEDs. Some of the most compelling new display products introduced in 2022, such as Quantum Dot-OLED, combine these technologies in new ways with incredible results.
In this keynote, Jason Hartlove, CEO of Nanosys, shares his vision for the next wave of display innovation being enabled by Quantum Dots, Phosphors, and OLEDs.
The significance of microdisplays, particularly OLED-on-Silicon microdisplays, have come to the forefront with the advent of AR/VR applications, With recent brightness and other improvements, OLED-on-Silicon microdisplays are considered the technology of choice for today’s AR/VR applications. This talk will discuss the key display requirements for AR/VR applications and how OLED-on-Silicon microdisplays are well positioned to meet them.
The next generation of OLED displays will offer more than lower power consumption and longer lifetime. They will also have improved color purity, due to reduced pixel cross-talk, and switching dynamics. Many of these new properties are related to the entire OLED stack design and this talk will explore how to optimize performance using our broad portfolio of materials.
We will show in this paper , both with simulations and experimental results that it is possible to significantly improve the outcoupling of the light from OLED pixels in a display (2.5-3.5 times) potentially reaching an outcoupling efficiency well above 50%, without creating optical crosstalk and loss of resolution. In a very close collaboration between teams in National Taiwan University (simulations and experiments) and Applied Materials (experiments) we developed a solution for the low outcoupling efficiency of light in OLED pixels (~20%) , by introducing some simple manufacturable changes in the pixel bank structure and the filling of the bank without modifying the OLED layer build up itself. We have shown that efficiency can be improved by 2.5 to 3.5 times.
Using a similar approach it is also possible to get a very narrow cone angle emission of OLED pixels, even in directions off the normal axis, with very high efficiency.
Despite the successes of OLED applications, research and development (R&D) mainly rely on costly and labor-intensive operations. The OLED device stack is designed and optimized by performing trial-and-error cycles that provide limited information about how the devices can be improved. All the stakeholders in the OLED industry are urgently looking for a breakthrough in their R&D approach. Thus, allowing for increased productivity and insights on the device functioning. Simulation software solutions are available to study disordered organic semiconductor devices that are based on different simulation methods. The most used methods are 1D drift diffusion, 1D or 3D Master Equation (3D ME) and 3D kinetic Monte-Carlo (3D KMC).An overview of the pros and cons of each of these simulations will be given. 3D-kMC currently is the solution allowing for predictive simulations and providing the highest level of insights at the device scale. Its only limitation can be the simulation speed. Fortunately, tremendous speedup improvements have been achieved with our 3D-kMC software, Bumblebee, thus making 3D-kMC the ultimate tool for OLED device R&D. These improvements will be presented during our talk. Finally, in this talk we will show how 3D KMC simulations can be used to understand and improve OLED devices. A selection of case studies that were performed with Bumblebee will be presented such as: - Multiscale toolchain: where input parameters needed for device scale simulations are automatically calculated based on the molecular structures. This approach allows for a seamless prediction of device properties starting from molecule compositions. Currently obtaining input parameters experimentally can be costly and time consuming, thus there is an increasing interest towards achieving a fully integrated toolchain that can simulate OLED devices from material parameters obtained with ab initio methods. Our recent progress on this multiscale toolchain will be presented based on industrial cases as well as devices studied by renowned research groups. - OLED Lifetime: where we will show how Bumblebee makes it easy to simulate OLED degradation scenarios and detect the key bottlenecks that limit device lifetime. Addressing these bottlenecks is then possible by material and stack design improvements.
