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.
Universal Display reported its financial results for Q1 2022, with revenues of $150.5 million and a net income of $50 million. UDC's results were better than expected as the adoption of OLED displays increases in AR/VR, smartphones, foldables, TVs, IT and automotive markets.
UDC reiterated its estimation that it will be ready to introduce a commercial blue PHOLED material to the market in 2024.
In 2016, Researchers from Japan's Semiconductor Energy Laboratory (SEL) announced a new OLED device architecture, called ExTET ('exciplex–triplet energy transfer'), that can increase the performance of OLED devices. The technology was applied for a patent in 2011.
The ExTET technology, which is a modification of the host material and the EML layer in phosphorescent OLED devices, have since been introduced to commercial AMOLED panels, increasing the efficiency and lifetime of the materials, while also lowering the drive voltage.
Universal Display reported its financial results for Q4 2021. Revenues for the quarter were $146 million, while net income was $46 million
UDC's 2021 revenues were a record high of $554 million, with a net profit of $184 million. UDC expects the OLED industry to continue to grow in 2022, and the company believes its revenues in 2022 will be between $625 million to $650 million (an increase of 12% - 17%).
Universal Display announced that Tianma Micro-electronics has extended its long-term OLED material supply and license agreement. UDC will continue to supply Tianma with its phosphorescent OLED materials and technologies.
UDC did not disclose any more details or financial terms. The original agreement between Tianma and UDC was signed in 2016.
Universal Display reported its financial results for Q3 2021. Revenues were a record $143.6 million, up from $117.1 million in Q3 2020 and net profit was $46.1 million (up from $40.5 million from Q3 2020). The company has about $789 million in cash and equivalents, the it reiterates its full-year 2021 revenue guidance to be between $530 million and $560 million.
Regarding its blue PHOLED R&D effort, UDC says it is making "excellent progress", and the company believes that a commercial blue material is a question of when and not if.
Hyperfluoresence emitter system developer Kyulux announced that its green material is getting close to commercialization. The company is now working closely with OLED makers, preparing for early adoption.
Kyulux says that its green emitter has not only met the required performance of OLED panel makers, in terms of efficiency, lifetime and driving voltage - but has actually surpassed the performance of green phosphorescent emitters in top emission devices. The green HF device achieves higher current efficiency, longer lifetime and offers a narrow emission spectrum and can thus enable better chromaticity.
During SID Display Week 2021, Kyulux detailed its latest TADF material performance. The red and green materials are "close to commercialization", and the company reports "excellent progress" with its blue emitter.
Using simulations, Kyulux shows how its Hyperfluorescence system is more efficient than a comparable phosphorescence emitter. While both emitters feature pretty much the same EQE, the narrow spectrum of the HF system which results in higher light intensity and can enable more efficient displays - by around 10%, according to Kyulux.
Universal Display and Visionox announced that the companies extended their long-term OLED material supply and license agreements. The new agreement runs for five years - that's the only details of the new agreement that has been disclosed.
The original agreement between Visionox and UDC was signed in 2018.
Universal Display and LG Display announced that the companies have extended their long-term agreements. LGD and UDC signed new OLED Technology License and Material Purchase Agreements. The new extended agreements run for five years.
UDC and LG did not disclose any further details or any financial terms. The two companies signed the original agreement in 2015.
