This session will feature presentations on innovations and trends effecting the efficiency and overall progress of the OLED from methods of manufacturing to materials.

LCD Display Market Share is trending down, OLED Share is trending up and MicroLEDs are tickling the imagination. This presentation will examine how the technologies will compete over the next 5-years, in terms of front of screen performance, cost of ownership, availability and application sensitivity. OLED are challenged to reduce costs, increase luminance, increase lifetime, adapt to environmental conditions, utilize capacity and develop new deposition technology for large area displays. The challenge for MicroLEDs is first to become relevant, produce a cost effective transport tool, increase efficiency for red and green LEDs, show the required uniformity for mass production and develop a cost effective approach for each targeted application.  Can LCDs keep up and for which applications. The following subjects will be covered:

• The current cost of OLED displays vs. LCDs
• Direct Patterning of OLED Micro Displays
• The cost of 1-4um LEDs manufactured on 4”, 6’ and 12” wafers
• The status of manufacturing R,G,B LEDs using GaN on a single wafer
• The status of MicroLED transport systems and their future
• How the luminance of an OLED display can be increased
• Yields for each technology
• Changes in LCD costs and performance
• Advanced methods of depositing OLED on large area substrates
• The role of IJP in OLEDs and Micro LEDs
• Methods of producing micro LEDs for AR/VR by technology

At the conclusion of the presentation, we will show the changes in performance and cost for each technology over a 5-year period.

Despite the successes of OLED applications, the research and development (R&D) processes still mainly rely on costly and labor-intensive experiment-driven trial-and-error approaches. OLED device manufacturers, chemical material suppliers and technology institutes are urgently looking for a breakthrough in their R&D approach, which should result in less development cycles and therefore in a significant reduction in time-to-market and increase in R&D cost effectiveness. In this talk, we will discuss the added value of predictive simulation software for OLEDs. With the help of predictive virtual experiments, we show how R&D time for OLED materials and devices can be effectively reduced by up to 40% and R&D cost effectiveness can be increased by up to 150%. Significant prototype- and experiment-based parts of the R&D process can be replaced by computer simulations. Additionally, experimentally inaccessible physical processes can be easily studied with only minimal effort required by the modeler. A wide range of possibilities for stack optimization then becomes available. At Simbeyond, we developed such predictive simulation software. With our Bumblebee software one can simulate the performance of OLED device stacks with complex 3D morphologies from the nanosecond up to its full lifetime. All relevant physical processes can be studied, including charge transport, exciton dynamics, loss processes and even degradation scenarios. Using Bumblebee, both the material and stack properties can be optimized simultaneously, thus revolutionizing OLED R&D. Simbeyond’s vision and progress towards achieving a complete end-to-end predictive device simulator from the molecule up to the device scale will also be presented. In Bumblebee, input parameters such as molecular energy levels or excitonic lifetimes are currently needed. In this future product, those input parameters will be accurately calculated using quantum chemistry simulations. Those properties will then be consistently scaled up all the way to the full device stack. This multiscale toolchain, which we are developing in collaboration with the Amsterdam-based company SCM, will enable efficient collaboration between chemical material suppliers and display manufacturers. This will ultimately reduce the number of OLED device development cycles and consequently increase R&D cost effectiveness.

The race to commercialize novel emitters for new-generation OLED displays reached a Milestone early this year when CYNORA made test kits available for its TADF-based Deep Green emitter. Known as the cyUltimateGreen™, it is the industry’s first commercial TADF-based product, and the first on CYNORA’s TADF roadmap that includes a Deep Blue emitter. To make its product development model leaner, faster and more targeted, CYNORA pioneered the Generative Exploration Model (GEM), a high-speed materials discovery engine. The GEM leverages the computational capabilities of AI to identify with extreme precision the most useful and relevant molecules from an infinite source of chemical molecules. When combined with the materials expertise and OLED device knowledge of CYNORA’s chemists and device physicists (AKA the Human Intelligence), the GEM enables CYNORA to identify molecules that are not just a theoretical fit, but ones that are chemically “synthesizable” as well. Using the GEM as an example, CYNORA CEO Adam Kablanian will describe AI’s capacity to transform materials research -- within the display industry and even beyond. He will explain how it is accelerating CYNORA’s product development initiatives. In addition, with new data to report on the cyUltimateGreen product, he will share an update. Finally, he will detail how CYNORA is applying critical learning from its first TADF-based product to speed development of a TADF-based Blue Emitter.

Future advancements in OLED displays depend on continued improvement and optimization of the constituent materials through rational design. Chemical innovation is needed to find solutions with superior efficiency, lifetime and processability. These required material performance improvements require both an efficient screen of large numbers of molecules and a conceptual understanding of the chemical properties leading to improved performance. The chemical design space for OLED materials is enormous, and complete enumeration to identify the most promising OLED material candidates for investigation remains impossible. Recent improvements in active learning lead to non-trivial improvements in intrinsic chemical properties at significantly lower computational cost than brute force high-throughput approaches. However, these intrinsic properties do not necessarily lead to better OLED materials. Deleterious interactions between adjacent compounds can preclude the use of many in practical applications. The effect of processing conditions and the resulting solid state effects alter the values and the distribution of controlling properties. It is through our combination of machine learning and physics-based approaches that material performance requirements can be met. Hole transport materials (HTM) are used in this paper to demonstrate the effectiveness of these discovery techniques.

Kyulux will demonstrate its coherent Hyperfluorescence™ development approach, consisting of comparative simulation, experimental demos, and a strategy towards high current efficiency alongside its new blue green and red TADF materials design principle for significant device lifetime improvement. These achievements were obtained by utilizing Kyulux’s “Kyumatic” Materials Informatics system. Kyulux plans to expand the capabilities of the Kyumatic system by adding more data and information about the durability of OLED devices. Since Hyperfluorescence™ works fourfold more efficiently than the conventional fluorescence according to the emitting mechanism, the revealed Blue Index (BI) simulation also complied with this tendency. Moreover, the intrinsically narrow bandwidth of Hyperfluorescence™ enables a much more superior efficiency growth when converting its bottom emission structure to top emission one. This feature makes Hyperfluorescence™ a more attractive OLED emitting technology over phosphorescence. In addition to the progress that stems from device optimization, Kyulux also will announce its latest lifetime breakthrough in blue and green TADF development. Based on the latest innovative materials design principle, the new TADF materials substantially improved the electron injection/transport issues, and the blue and green TADF device lifetime has also been prolonged by 5 and 1.65 times, respectively. With these fruitful Hyperfluorescence™ improvements within a short period of time, Kyulux has the confidence to predict further significant performance growth and should be ready for practical mobile applications shortly.
