LG Display Beats the Industry to Mass-Producing Blue PHOLED
In a move that could finally complete the OLED trinity, LG Display has become the first company in the world to mass-produce blue phosphorescent OLED panels. The breakthrough is being hailed as the missing puzzle piece in the long-promised “dream OLED,” where red, green, and now blue light are all emitted through ultra-efficient phosphorescence.
LG Display unlocks blue PHOLED tech
Historically, blue OLEDs have been a nightmare for engineers. They burn out faster, drain more power, and are notoriously difficult to stabilize due to their high-energy, short-wavelength emissions. While red and green phosphorescent OLEDs have long been in commercial use, blue has stubbornly remained fluorescent, offering lower efficiency and higher power demands.
Now LG Display, in collaboration with Universal Display Corporation (UDC), has cracked the code. The company’s new hybrid Tandem OLED stack places a blue fluorescent emitter below a blue phosphorescent one. The result is a display that cuts power consumption by about 15 percent without sacrificing lifespan, achieving a rare balance of efficiency and stability that has eluded OLED researchers for years.
LG’s dual-stack approach is not just a technical workaround, it is a manufacturing-ready solution. The company has already verified its viability on real production lines and filed patents in both South Korea and the United States. A prototype will debut at SID Display Week 2025 in San Jose, with small and mid-size panels aimed at smartphones, tablets, and eventually AI PCs and AR/VR devices.
For years, insiders expected Samsung to win this race, with rumors swirling around a debut in the Galaxy Z Fold 7. But LG got there first, and this might be the OLED revolution that makes your next screen brighter, thinner, and far more efficient.
While LG Display breaks new ground in OLED science, its sibling company LG Electronics is quietly leaning on TCL to stay competitive. LG’s latest QNED evo TVs, aimed at reclaiming lost ground from Samsung and Hisense, are built using MiniLED panels manufactured by TCL, the very rival that’s rapidly expanding its global footprint. In fact, after LG sold its final LCD factory to TCL, much of its new panel supply is now sourced straight from China.

TCL CSOT to Announce Gen-8 Inkjet OLED Investment Soon, Achieves 350PPI Milestone
TCL CSOT is preparing to announce its Gen-8 inkjet-printed OLED (IJP OLED) production line investment between August and September this year. Zhou Mingzhong, Head of Technology Planning at TCL CSOT, confirmed the development during an interview after the Seoul Display Business Forum. The company is currently discussing the project with local authorities, which has slightly delayed the official announcement.
TCL CSOT has achieved a pixel density of over 350 pixels per inch (PPI) on its inkjet OLED panels. The company uses an RGB sub-pixel arrangement with equally sized sub-pixels, which eliminates the size imbalance typically seen in FMM OLEDs, especially with the larger blue pixels. Zhou stated that the blue OLED device’s LT95@100nits lifespan will reach 400 hours by 2026, a tenfold improvement over 2020 figures.
The company claims its inkjet OLED panels have an aperture ratio three times higher than conventional fine metal mask (FMM) OLED displays. This improvement is expected to enhance brightness efficiency and extend the overall durability of the panels.
TCL CSOT currently operates a Gen 5.5 inkjet OLED line at its T5 facility in Wuhan. It manufactured 21.6-inch medical OLED panels using this process in late 2024. The new Gen-8 line will support larger substrates, which are better suited for televisions and monitors.
During the forum, Zhou also highlighted potential applications for the technology. TCL CSOT has developed a 6.5-inch smartphone panel with 325PPI, a 14-inch 2.8K laptop display with 243PPI, a 27-inch 4K monitor with 163PPI, and a 65-inch 8K TV panel with 136PPI. The company displayed several of these prototypes at SID 2025.
The Gen-8 investment marks a strategic step for TCL CSOT as it aims to compete with South Korean display makers in the high-end OLED market.

Cerence Files IP Complaint Against Sony and TCL Over Voice Technology in Smart TVs
Cerence Inc., best known for its conversational AI in cars, is going on the offensive, this time against two global electronics giants. The Massachusetts-based voice tech firm has filed a formal complaint with the U.S.
International Trade Commission (ITC), accusing Sony and TCL of infringing its patented voice technologies in their smart TVs. In tandem, the company has launched lawsuits in the U.S. District Court for the Eastern District of Texas, aiming for damages and broader IP enforcement.
Cerence claims that specific smart TV models from Sony and TCL illegally use its proprietary voice interaction technology. The company is urging the ITC to issue a limited exclusion order, which could halt the import of those devices into the U.S. entirely.
“We will take strong, decisive action to protect our IP rights and prevent the unauthorized use of our technology,” said Jennifer Salinas, Cerence’s Chief Administrative Officer and General Counsel. The company argues that safeguarding its innovations isn’t just about business, it’s a strategic imperative tied to the protection of its customers and long-term investments.
Cerence, which already powers voice features in over 525 million vehicles globally, is signaling that its tech ambitions extend well beyond the dashboard. By targeting smart TVs, the company is asserting that its voice control patents have wider relevance in the growing smart home and entertainment landscape.
But lawsuits of this magnitude don’t come without risk. Suing two massive hardware players could drain resources and test business relationships, while the legal outcome remains far from guaranteed. Still, the move underlines a broader theme in tech: as AI capabilities become core to consumer electronics, the fight over who owns the underlying technology is only heating up.

Samsung Launches Four New Odyssey Gaming Monitors Featuring TCL CSOT Display Technology
Samsung has launched four new Odyssey series gaming monitors at ChinaJoy 2025, incorporating advanced MNT display technology from TCL CSOT. The announcement marks a significant step in Samsung and TCL CSOT’s partnership, aiming to push the boundaries of esports-focused display performance.
TCL CSOT showcased three new display technologies tailored for different gaming genres: HVA Fast, HVA Black, and HFS Shoot. HVA Fast supports a 1ms response time and offers curved panels in sizes ranging from 34 to 57 inches with a 1000R curvature. HVA Black features a 5000:1 native contrast ratio and supports refresh rates up to 500Hz, offering high clarity and dynamic visuals. HFS Shoot targets FPS players with support for high resolution, high refresh rates, and autostereoscopic 3D switching without glasses.
Samsung’s new lineup includes the 27-inch UHD 165Hz Odyssey G90XF, the 40-inch WUHD 180Hz Odyssey G75F, the 37-inch UHD 165Hz Odyssey G75F, and the 27-inch UHD 180Hz Odyssey G70F Dual-Mode Gaming Monitor.
The Odyssey G90XF is Samsung’s first gaming monitor to feature glasses-free 3D. It uses light-field display (LFD) technology combined with an eye-tracking camera to produce real-time 3D visuals without any viewing angle restrictions. The display supports AI-powered 2D-to-3D video conversion and features 4K resolution, a 165Hz refresh rate, spatial audio, and environmental lighting effects. Samsung launched the G90XF in May at a price of 14,999 yuan ($2,080).
The 40-inch G75F supports a resolution of 5120×2160, a 180Hz refresh rate, and a 3000:1 contrast ratio with support for 1.07 billion colors. The 37-inch G75F and 27-inch G70F monitors both support 3840×2160 resolution, high refresh rates, and AMD FreeSync Premium Pro for smoother gameplay across supported titles.
These monitors aim to meet the evolving demands of esports gamers, with TCL CSOT playing a central role in the display technology behind them.
