OLED-Info: the OLED experts

LG Display and Tianma settled their long LCD and OLED display global patent dispute. The two companies have notified the U.S. Patent Trial and Appeal Board (PTAB) of the settlement and agreed to withdraw all related lawsuits.

While we do not have specific information, we do know that Tianma will start paying patent license fees (or royalties) to LG Display, in exchange to access to LG's IP.

Researchers from Kyoto University, have developed a new molecular design concept for MR-TADF OLED emitters, that spatially expands and amplifies the multiple resonance effect. 

The new molecule, called m-CzB10-Mes has a nano-carbon framework, with a ladder-type structure, and it achieved an emission bandwidth dramatically smaller than those of conventional multiple resonance emitters. Furthermore, the molecule also exhibits excellent TADF performance. 

Researchers from Seoul National University have developed high-performance flexible transparent electrodes, using selective metal deposition. They have successfully implemented these electrodes in a top-emitting OLED device, to demonstrate the effectiveness.

To create these electrodes, the researchers developed a novel metal patterning technology, based on a metal vapor desorption layer (MVDL). MVDL can enable high-resolution metal mesh patterns, down to only a few micrometers (μm), without the need for chemical cleaning or lift-off processes. This helps minimize the damage to the underlying organic layers.

Reports from Korea suggest that Visionox has increased its ViP AMOLED display capacity, at its low-volume pilot line, located at its V3 production line in Hebei, China. 

According to the reports, Visionox started producing ViP smartphone and wearable OLED panels, supplying these to Xiaomi and Honor. 

Researchers from Zhejiang University of Technology have designed a high performance green phosphorescent OLED emitter, that offers a record lifetime of 540,100 hours, LT90 at 1,000 cd/m².

The new green emitter offers a very narrow emission, 14.8 nm FWHM (CIE 0.22,0.75), and a high current efficiency of up to 174 candela per ampere. 

According to Sigmaintell, the average utilization rates in Chinese 6-Gen flexible AMOLED production lines declined from around 80% in Q4 2025 to 69% in Q1 2026. 

Sigmaintell says that the main reason for the decline is lower demand from Chinese smartphones makers as they face a declining market, and increased component costs (mainly memory chips). In addition, some companies have large inventories of panels. 

A couple of months ago we reported that  the Korean Supreme Court upheld the validity of SFC's blue OLED emitter patent, and did not accept the claims by SK Materials JNC (SKMJ) that the patent was invalid.

Now we hear from Korea that SFC has won a civil lawsuit against SKMJ, and was awarded with 100 million Won in damages ($65,000 USD) plus all litigation expense. SFC was also seeking to ban SKMJ from marketing this material, and its likely that this is part of the court's decision.
