OLED displays are now in commercial production for a range of products from cell phones, tablets, UHD TV’s, and newly emerging applications such as AR/VR headsets, laptop displays, wearable devices and solid-state lighting. UDC is a pioneer in the development and supply of phosphorescent OLED technology and materials for both energy efficient display and lighting applications. In this presentation we outline how we are ensuring that our PHOLED technology roadmap meets the ever more demanding performance requirements of future products, and expand the OLED market. In particular we outline our organic vapor jet printing (OVJP) for depositing patterned small molecule organic materials to manufacture large area side by side R-G-B OLED TVs, and our development to enable the introduction of our all-phosphorescent RGB stack into the commercial market in 2024. We also compare OLEDs with microLEDs, and note that while future microLED displays offer potential benefits of lower pixel fill-factors enabling the integration of additional components at the pixel level or achieve increased transparency, OLEDs can achieve comparable power efficiencies with a roadmap to ultra low power consumption.

Digital OLED as enabler for personalization of exterior lighting design

• Car-2-X- communication by multi-segment OLED technology
• Automotive OLED lighting future towards high brightness exterior display

Dr. Werner Thomas | Project Manager OLED-Lighting, AUDI AG

The Innovation in Display Technology is at an All-Time High Level Seeking for differentiation and diversification. New materials, new form factors demand new (laser) processes to produce OLED displays for mobile phones and IT panels on industrial standards. The IT panel market has experienced a strong growth in the past years. Currently, there are many discussions and evaluations ongoing about high-end OLED based tablets, notebooks, and foldable devices coming with a larger size compared to the well-established mobile OLED devices.  Coherent has the broadest laser portfolio and is the only supplier offering all types of lasers and optics for the FPD industry! We will present the laser processes along the production of an OLED display and how we support the increasing size of high-resolution OLED displays in the future.

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.

We are in a paradigm-changing era in the way scientists’ experiment. Many fields such as automotive engineering and particle physics have relied on accurate simulation to design parts
and experiments. In recent years computational chemistry has joined this paradigm with a rich
set of capabilities at the atomistic and coarse-grained scales to accelerate materials
development. In this talk, critical case studies illustrating the latest physics-based simulation
technology combined with genetic optimization, active learning, and AI generative models for
the design and optimization of OLED materials will be presented. Finally, real-time collaboration enables multidisciplinary teams to amplify their collaboration on a global scale.

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.
