Tianma is showing its latest OLED display prototypes at SID Displayweek 2026. First up we have a 6.58" AMOLED that adopts Tianma's latest U11 OLED stack, which utilizes a a PSF emitter system (likely green, but Tianma did not specify) and also a new fluorescence emitter system which Tianma calls NFT (New Fluorescent Technology) based on New Fluorescent Blue (NFB). 

Tianma says that the new NFT device structure improves exciton utilization efficiency, and utilizing these new technologies, the U11 reduces overall power consumption by approximately 12% compared to Tianma's previous stack, while doubling lifespan. The optimized RGB spectrum and light-extraction design also enable an ultra-low blue-light ratio while maintaining high efficiency.

LG Display is showcasing a wide range of OLED displays and prototypes at SID Displayweek 2026. In this article we detail the most interesting demonstrations and technologies.

First up, is LG's 3rd-Gen Tandem OLED, these are AMOLED displays, aimed towards the automotive market. LG says that it has introduced two new technologies into its tandem stack - a deep-blue dopant and optimized hole and electron movement. It isn't clear exactly what LG refers to, but it does say that these new technologies enable tandem OLEDs with improved power consumption (18%), brightness (1,200 nits), lifetime (over 15,000 hours) and color purity and reproduction. 

Researchers from Inha University and Pusan National University have developed a the world's highest-efficiency solution-processed blue OLED device, achieving an EQE of 36.7%. As TCL CSOT gears up to begin OLED mass production utilizing inkjet printing, there is renewed interest in soluble OLEDs.

To create this new device, the researchers developed a new OLED emitter, a platinum(II) complex, "PtON-QBn", and also introduced a new "PVK Template Layer" in the OLED device stack.

According to reports, the Korean Supreme Court upheld the validity of SFC's blue OLED emitter patent, and did not accept the claims by SK Materials JNC that the patent was invalid.

This patent dispute started in 2020, when SK Materials JNC filed the patent invalidation application, and the patent court held the patent as valid in the summer of 2024. SK Materials JNC then appealed to the supreme court.

OLED material developer LORDIN says that it hopes to start mass producing its high-efficiency blue phosphorescence OLED emitter by the end of 2026, after having verified the commercial feasibility of the material a few months ago.

Following six years of intensive research and development, LORIND's Jetplex ZRIET platinum phosphorescence blue OLED emitters seem to be on the verge of mass production, with improved stability - the material lifetime is said to be suitable for commercial AMOLED displays. LORDIN says that its materials also improve over current phosphorescence emitters with lower driving voltage, and better efficiency degradation (roll-off) at high brightness. 

Germany-based beeOLED announced that it has been awarded a 2.5 million Euro project by the European Innovation Council (EIC), as part of the EIC Accelerator Program, to support its work on blue OLED emitters. 

The company says that the project, called beeUP, will enable beeOLED to scale up its operations and accelerate its R&D, preparing its intra-metallic emission materials for for market readiness. The project started in October 2025, and will have a duration of two years. 

NHK Science & Technology Research Laboratories (STRL), in collaboration with Professor Hirohiko Fukagawa from Chiba University, has developed an OLED display device that can emit light while simultaneously harvest solar energy. NHK says that this is the first time that such a device has been developed, where it is capable of blue light emission.

The basic idea behind the new device is that it is capable of quickly alternating between emitting light and generating electricity. The device is also quite efficient in both its light emission and energy generation.

Researchers from the University of Michigan and The Pennsylvania State University, in collaboration with OLEDWorks, has managed to create high aspect ratio OLED devices, by fabricating the OLEDs on substrates with sub-millimeter, high aspect ratio surface textures. This design increases the active OLED area per panel, reducing the local current density needed to achieve a given luminance.

The researchers report that this approach can extend the lifetime by up to 2.7X, this was verified on a blue fluorescent OLED device. These devices also offer up to 40% higher light extraction efficiency, as the corrugated substrates scatter the trapped light, significantly boosting EQE.

Japan-based TSK Corporation announced that it is collaborating with Samsung Display for the full-scale development of blue OLED display materials, based on the company's iron catalyst technology. The two companies are developing host and electron blocking materials.

TSK explains that in most OLED synthesis, palladium catalysts are used. But palladium is a rare metal primarily sourced from Russia and South Africa, and it is also expensive and polluting. TSK developed a proprietary, environmentally friendly chemical process that uses iron, a naturally abundant metal, as a catalyst in place of the palladium.
