Berlin Time

Online Event

Event Description

This is part of the display series at TechBlick and MicroLED Connect

It will focus on innovations in materials, manufacturing, applications, and markets for OLEDs.


OLEDs are already a commercial success for years and yet the the pace of incremental and radical technological innovations and breakthroughs is incredible, furthering device properties [color, stability, resolution, color gamut, brightness, etc], expanding applications, and opening new manufacturing and patterning techniques from photolithography to printing and beyond. 


These are incredible innovations that could not only entrench the success of OLEDs further, addressing their weak spots, but also perhaps take away the selling points of challengers or alternatives like MicroLEDS, QD-LCDs, etc. 


It is incredible how dynamic this innovation level in this field remains after decades of development and manufacturing 

This is curated by TechBlick and OLED-Info.com

Choong Hoon Yi

CEO

The OLED industry is slowly moving from smartphones and TVs to IT and automotive. The global OLED production capacity for smartphones is 1 billion units, and the Chinese smartphone market is rapidly increasing the use of OLEDs, so LCD lines below 6G will gradually lose their value. The ignition of the OLED market for IT is driving investment in 8.6G equipment. The investment in OLED lines for IT by Korean and Chinese companies is expected to start with tablet PCs and expand to laptops and monitors. Increased investment in OLED for IT will also depress the value of 7G LCD lines. Expectations for micro-OLED market growth are being fueled by Apple Vision Pro. Korean display companies are also investing in mass production equipment in anticipation of MR device market growth. The Korean display industry, which has the best OLED manufacturing technology, will dominate the micro-OLED market.

Maximilian Mosberg

Business Development and Sales

Traditionally manufacturing of electronic components has not been sustainable as the involved process steps waste a lot of material and require large amounts of energy and use toxic agents. Typically, electronics are manufactured via a cycle of homogenous functional material application, exposing of the design onto the applied material and material stripping of which can result in extensive wastage of the functional material. A more sustainable approach to electronics manufacturing is offered by inkjet and EHD as these technologies are built on an additive approach to manufacturing instead of a subtractive one. By additively applying functional material only where required according to the final product design, material and energy waste is minimized while increasing throughput at the same time due to eliminating the need for design specific tooling and reducing the amount of equipment required. This approach can be applied to a multitude of industries that profit from reducing functional material waste such as the manufacturing of displays, electronics, automotive, glass, semiconductor, 3d printing or solar. Inkjet printing of functional materials is a digital structuring process that can be used for a contactless application of a wide range of different materials without the need of a mask. It is suitable for mass production as well as to produce small batch sizes and for rapid prototyping due to the high potential to customize the individual printed structures. The process involves transferring metals, polymers, and ceramics into low viscous inks in the typical range of 2-15 cPs at processing temperature. These inks can then be applied to a surface by jetting the material through individual nozzles of a print head. For drop on demand placement required for the manufacturing of electronics typically piezo based print heads are used. These print heads can be equipped with over one thousand nozzles each. By integrating multiple print heads into one inkjet printer brings the total to multiple thousand nozzles per system. This in turn allows printing on large surface areas and enables high throughput electronics manufacturing with printable surface areas ranging from the micrometer to the square meter scale. By combining multiple print heads, each with their own ink delivery, it is possible to print multiple materials in one inkjet printing system which in turn allow the fabrication of highly advanced multiple material electronics in an additive fashion. Depending on the material printed, single dry layer thicknesses of 50nm – 20µm can be achieved. By printing multiple passes high layer thicknesses and three-dimensional objects can be manufactured such as lenses, sensors and displays. Electrohydrodynamic (EHD) printing is an alternative method to conventional inkjet printing of functional materials. The key difference between piezo based inkjet and EHD inkjet is how the energy is created to eject the individual droplets from the nozzles. Whereas inkjet uses piezo elements within the printheads to push ink from the inside, EHD utilizes electrical fields to pull out the ink by potential difference between ink and substrate. By this focused application of energy to eject ink from the nozzle it is possible to eject submicron droplets which in turn allows creating structures with feature sizes of < 0,5 µm. The other key advantage of focusing energy is being able eject droplets of highly viscous ink with < 10.000 cPs at working temperature. The EHD MEMS printhead approach makes it possible to have thousands of individual EHD nozzles in close proximity to one another, while still being able to address each nozzle individually and increases the working distance between the printhead and the substrate to >1mm. This new MEMS printhead approach brings an unprecedented scalability to EHD printing. The print head design is key to enable stable and high throughput printing with EHD in different modus operandi such as a high-speed vector printing, digital multi nozzle printing or bitmap printing. EHD is compatible with a wide range of materials such as nanoparticles, small molecules, polymers, salts, melts and biomolecules.

Margaret Kocherga

CEO and Founder

While OLEDs are traditionally regulated to display technologies, they have seen increasing demand in recent years for lighting. Inorganic LEDs are often the go-to choice for lighting in the modern world. Still, their excessive heating, high power demands, and use of scarce elements require alternatives for transportation, AgTech, packaging, medical devices, and wearables. Such demand results in the need for materials that enable rapid OLED manufacturing on a large scale without sacrificing efficiency, do not utilize scarce elements, and lower power consumption. Margik will present the importance of novel solutions for charge transport materials, which play a crucial role in performance efficiency and can assist in lowering turn-on voltage. Our multifunctional transport materials are based on coordination compounds and utilize elements from p-block.

Franco Egidi

Software Developer

The accurate modeling of complex multi-scale molecular structures poses a significant challenge in computational chemistry, particularly in addressing the intricate properties of OLED materials. While considerable efforts have been devoted to developing precise methods for simulating either isolated molecules using ab-initio quantum chemistry techniques or larger structures using classical mechanics, the demand for accurately describing highly complex systems like OLED materials necessitates an integrated approach, as OLED properties are governed by intricate quantum mechanical interactions arising from numerous intermolecular forces that depend on the material’s composition. To address this challenge, SCM has developed a comprehensive workflow that enables the seamless simulation of OLED materials, leveraging cutting-edge methods encompassing both classical and quantum approaches, allowing researchers to expedite the development of new OLED stacks by screening and selecting the most promising combination of materials. This streamlined approach not only accelerates the discovery process but also enhances the efficiency of materials design and the optimization of next-generation OLED technologies. The workflow comprises two primary steps: molecular component deposition and property simulation. In this presentation, we elucidate our workflow, present key findings, and unveil the latest advancements that enhance the accuracy of our results. Our approach not only facilitates the exploration of OLED material properties but also marks a significant step towards understanding and optimizing these crucial technologies. Additionally, the results from our atomistic calculations can be used in mesoscale kinetic Monte Carlo (kMC) simulations for device-level modeling, enabling the prediction of external quantum efficiency, J-V curves, and other important device characteristics for OLED stacks.

Paul Blom

Director

The efficiency and stability of single-layer polymer light-emitting diodes is compromised by unbalanced charge transport, the absence of triplet-exciton harvesting and low photoluminescence quantum efficiencies. We demonstrate that using thermally delayed activated fluorescence emitters in combination with trap-free transport internal quantum efficiencies of unity are obtained, resulting in high external quantum efficiencies of 28%. Our results show that OLEDs with a simplified single-layer structure can rival the efficiencies of complex multilayer stacks.

Stable and efficient phosphorescence blue OLED emitters - latest research report

Haonan Zhao

Doctor of Philosophy - PhD

This presentation will introduce the phosphorescent organic light emitting devices (PHOLEDs) lifetime problems and lifetime extending techniques. Due to their vibrant colors and high efficiencies, PHOLEDs have been widely used in both display and lighting applications. However, stability remains a significant issue for blue PHOLEDs, hindering their widespread application. In the recent study, the polariton-enhanced Purcell effect has been found to efficiently increase the device operational lifetime by a moderate estimate of 10-14 times compared to the reported similar PHOLED devices up to date. The newly discovered plasmon-exciton-polaritons (PEPs) and cavity structures enable phosphors to emit faster without compromising their external quantum efficiency. The increased radiative emission rate in an optical cavity, known as Purcell effect, is modulated by the Purcell factor contributed by the PEPs. Our results also show the analytical dependence for the device lifetime on the Purcell factor, emission color etc. This method can be combined with other lifetime extending techniques, paving the way for stable, efficient PHOLED display and lighting applications.

Our results also show the analytical dependence for the device lifetime on the Purcell factor, emission color etc. This method can be combined with other lifetime extending techniques, paving the way for stable, efficient PHOLED display and lighting applications.
