OLED-Info: the OLED experts

The supreme court in Korea has made a final decision, dismissing SFC's patent lawsuit against LG Chem, regarding the company's deuterated OLED compound. The court has found that LG Chem's materials are not substantially identical to existing technology and possessed an inventive step, thus warranting the patent.

The lawsuit was originally filed by SFC together with Idemitsu Kosan. The patent in question was acquired from DuPont in 2019. SFC and Idemitsu claimed that the only change LG Chem performed is increased the deuteration rate to 40% (from 36% in existing solutions), but the court says that in addition to the increase there was also substantial technical achievement in the process.

A couple of months ago we reported that Samsung Electronics, aiming to reduce its cost structure, has ordered 15 million AMOLED panels from CSOT, that are adopted in the 2026 Galaxy A57 and S FE models smartphones.

According to a new report from Korea, Samsung is in talks with BOE to the supply of more advanced AMOLED displays that will be used in the basic model of the flagship Galaxy S27 smartphone.

BOE is accelerating its B16 8.6-Gen IT AMOLED fab in Chengdu, and according to the latest updates from Korea, the company will begin mass production by the end of this month (May 2026).

BOE's first products out of this new line will be 14-inch laptop OLED panels, and it will supply the first batch to ASUS and Acer (this was already reported last year). It is likely that BOE will take time to fully ramp up the new production line, but the first commercial production is an important step.  BOE originally planned to begin production towards the end of 2026, but it has managed to accelerate and begin production sooner.

Reports from Korea suggest that BOE will begin supplying 24.5" WOLED (WRGB) monitor panels to ASUS. BOE will start shipping panels later this year.

It is reported that this will be the first time that BOE ships commercial panels out of its WOLED 8.5-Gen pilot line in Hefei, but the company is actually already shipping some commercial panels. In any case, the quantities will be limited (as the pilot line capacity is very small).  

UBI Research says that 190 million OLED smartphone panels shipped in Q1 2026, down 12% from last year, and down 20% from the previous quarter. UBI says that the decline in shipments is mainly due to rising memory prices.

Samsung remained the leading AMOLED smartphone producer, with a 44.4% market share in the quarter, up from 42.8% last year. LG Display, with a 9% share, also increased its market share (which was 7.6% in Q1 2025). 

Researchers from POSTECH (Pohang University of Science and Technology) have developed a next-generation laser platform that integrates OLED emissive materials with chiral liquid crystals (CLCs). The researchers show that this new laser offers precise color control under battery-level low voltage - basically a color-tunable emitting laser.

The researchers say that the helically ordered structure of CLCs forms a periodic resonant cavity capable of selectively amplifying specific wavelengths. The CLC was transformed it into laser-like emission by coupling it with a broadband-emission OLED device. The device offers ultra-narrow linewidth of approximately 1 nm (FWHM), achieving color purity tens of times higher than that of conventional OLEDs.
