Nanomatch announces a novel class of emitters for efficient and stable blue OLEDs

This is a sponsored post by Nanomatch

Using their in-house virtual design tools, Nanomatch developed a new class of emitters that enables the production of stable, fluorescent OLED devices with close to 100% internal quantum efficiency also in the blue color range.

The specific class of fluorescent emitters facilitates the generation of only singlets with radiative decay of the order of 10-8s, thereby eliminating quenching processes induced by long-lived triplets. Having filed the patent end of February 2023, Nanomatch is now looking for partners to commercialize this new concept in order to realize efficient, stable blue OLEDs on an industrial level.

Researchers developed a high performance, low-cost HIL material for solution-processed OLEDs

Researchers from Korea's Pusan National University have developed a new low-cost hole injection layer (HIL) material for solution-processed OLEDs, achieving higher efficiency and lifetime compared to the current state-of-the-art.

The new material is solvent-resistant (>99%) and thermally cross-linkable. The researchers used this material to create a solution-procssed red phosphorescent OLED device. The researchers placed the material between the ITO electrode and the HTL material, thus achieving photo-crosslinking of (poly-TPD) as HTL on top of crosslinked HIL.

Universal Display reports its Q4 2022 financial results

Universal Display Corporation reported its financial results for Q4 2022, with revenues of $169 million and a net income of $65 million. Looking at 2022 as a whole, revenues reached $617 million (up 11% from 2021) while net income was $210 million, up 14% from 2021. The company ended 2022 with $826 in cash and equivalents.

UDC reported excellent financial results for Q3 2022

Universal Display reported its financial results for Q3 2022, with revenues revenues reaching a record high of $161 million, and a net income of $53 million. The company reiterated its forecast for 2022, with revenues of approximately $600 million, plus or minus $10 million.

Researchers develop the world's most efficient single-layer PHOLED emitter

Researchers from the Université de Rennes in France have developed a simplified PHOLED green emitter that achieves the world's highest efficiency in single-layer PHOLEDs - an EQE of 22.7%.

The researchers, led by Prof. Cyril Poriel, say that the emissive layer was developed using a rational molecular design. The impact of the phosphorescent emitter on the ambipolarity of the charge transport is particularly evidenced and appear as a key concept in the high performance that was achieved.

DSCC: OLED material sales to reach almost $3 billion by 2026

DSCC updated its OLED material market data, and it now sees AMOLED stack material revenues growing at a 18% from 2020 ($1.07 billion) to 2026 ($2.9 billion). If UDC actually manages to release a commercial blue PHOLED, the market could even exceed $3 billion.

Kyulux explains how narrow-spectrum Hyperfluorescence emission is more efficient than PHOLED emission

Second-generation OLED phosphorescence emission features an internal quantum efficiency of almost 100% - which would normally mean you cannot get more efficient than that.



As Kyulux explains in a recent post, though, phosphorescent suffers from a wide emission spectrum. In order to achieve a good color gamut (for which as narrow-spectrum emission as possible is best) display makers have to filter out the "tail" of the emission. This results in reduced brightness and efficiency.
