Summary of the clip:
How can next-generation maskless deposition transcend the limits of conventional solution processing for advanced organic and inorganic thin films?
The evolution of organic vapor jet printing (OVJP) into reactive UVJP represents a paradigm shift in additive manufacturing, enabling the solvent-free, maskless deposition of non-volatile thin films from reactive precursors. By bypassing the solubility constraints that typically plague liquid-phase processing, this dry, carrier-gas-assisted technique expands the printable material suite to include high-purity metal oxides, thermoplastic and UV-curable polymers, and delicate organic semiconductors.
From an engineering perspective, reactive UVJP offers unprecedented process flexibility, operating seamlessly across a pressure spectrum from high vacuum to atmospheric conditions. The system achieves precise, angstrom-to-micron thickness control and high deposition rates regardless of substrate orientation, while maintaining exceptional source utilization efficiency through the active reclamation of unreacted precursors and reaction byproducts.
Beyond traditional optoelectronic applications like phosphorescent OLEDs, OTFTs, and OPVs, this technology is pioneering new frontiers in pharmaceutical manufacturing and surface engineering. By leveraging solvent-free deposition of small-molecule active pharmaceutical ingredients (APIs), it enables the fabrication of novel drug-delivery films with precise, graded concentration profiles across the film thickness—a structural architecture virtually impossible to achieve with conventional wet-chemistry methods.
In this short video, you can learn:
* How reactive UVJP enables the solvent-free deposition of polymers, metal oxides, and small molecules.
* The operational advantages of the process, including high source utilization, conformal 3D coating, and wide pressure tolerance.
* New applications in pharmaceutical manufacturing, specifically the fabrication of graded-concentration API thin films.

Can physics solve the ultimate lifetime bottleneck of blue phosphorescent OLEDs where chemistry has failed?
Can physics solve the ultimate lifetime bottleneck of blue phosphorescent OLEDs where chemistry has failed?
Traditional organic light-emitting diode (OLED) development relies heavily on molecular engineering to improve materials' lifetime and efficiency. However, as emitter limits are reached, particularly in the challenging blue spectrum, physical device architectures must step in. Universal Display Corporation is addressing this limit through the development of the plasmonic OLED, which shifts the performance improvement mechanism from chemical synthesis to device physics.
The plasmonic OLED stack works by deliberately quenching excited state particles (excitons) in the emissive layer directly into the metallic cathode, converting them into surface plasmon polaritons. These polaritons are then outcoupled and radiated into free-space photons using a periodic nano-antenna array fabricated over the device. Because energy is rapidly transferred out of the organic layers and emitted externally, the stack avoids typical high-energy exciton degradation pathways.
This decoupling of exciton decay from the internal organic layer stack dramatically increases outcoupling efficiency and improves device lifetime by 5x to 10x. By altering the local electromagnetic density of states, the plasmonic architecture bypasses conventional internal absorption losses. This breakthrough is critical for highly demanding display applications, such as high-brightness AR microdisplays and next-generation mobile panels.
In this short video, you can learn:
* How the plasmonic OLED leverages surface plasmon polaritons and nano-antennas to bypass internal absorption losses.
* The physical mechanism behind the 5x to 10x lifetime increase achieved by quenching excited states into the cathode.
* Why physical stack design is overtaking traditional molecular chemistry to unlock the next level of display efficiency.
📋 **Clip Abstract** This clip introduces the plasmonic OLED, an innovative device architecture developed by Universal Display Corporation to enhance OLED efficiency and lifetime. By utilizing a nano-antenna array to outcouple light from quenched states at the cathode, this technology achieves a 5X to 10X lifetime improvement.

Why is the display industry desperately trying to eliminate solvents from the fine-metal maskless manufacturing pipeline?
Why is the display industry desperately trying to eliminate solvents from the fine-metal maskless manufacturing pipeline?
Solution processing of organic electronics has long promised low-cost display manufacturing, but solvent ink formulations present persistent challenges, including film impurities, uncontrolled drying kinetics, and chemical degradation of underlying layers. To solve these issues, Universal Vapor Jet Printing (UVJP) introduces a completely dry, solventless deposition technique. This method carries vaporized organic molecules directly in an inert carrier gas stream to print functional patterns.
The gas-phase carrier system allows for highly precise mass-flow control, enabling co-deposition of multiple source materials simultaneously from distinct sublimation sources. This capability enables the generation of complex, multi-component organic layers with sharp or diffuse heterojunctions inside a single deposition run. Engineers can programmatically vary the material ratios during growth to achieve compositionally graded active layers.
Scalable to large mother glass substrates (Gen 8 to Gen 10), UVJP offers precise digital thickness control from single angstroms to several microns. By eliminating liquid solvents, the process preserves organic molecular integrity and simplifies the deposition chamber environment. This solvent-free pathway represents a major commercial opportunity to manufacture high-efficiency OLEDs, organic photovoltaics, and thin-film transistors with high material utilization.
In this short video, you can learn:
* How Universal Vapor Jet Printing carries vaporized molecules in an inert gas to achieve solventless deposition.
* The process controls that enable co-deposition of multiple materials to print compositionally graded layers.
* The scalability of dry vapor jet printing to large-area display substrates up to Gen 10 mother glass.
📋 **Clip Abstract** Mike Hack explains the core advantages of Universal Vapor Jet Printing (UVJP), highlighting its dry, solventless process and precise thickness control. He details how the technology enables the co-deposition of graded multilayers without solvent-induced chemical degradation.
