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.

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.
