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 exclusively supplies displays for both Xiaomi 17 Ultra and 17 Ultra Leica Edition
TCL CSOT has confirmed that it is the exclusive display supplier for Xiaomi’s latest flagship smartphones, the Xiaomi 17 Ultra and Xiaomi 17 Ultra Leica Edition. Both models feature a 6.9-inch quad-equal-bezel flat display, which is custom-built by TCL CSOT. The panel supports a peak brightness of 3500 nits and features a 1-120Hz LTPO adaptive refresh rate.
The display uses TCL CSOT’s latest light-emitting materials, which are designed to deliver high color accuracy, low power consumption, and fast response times. According to the company, this flat display solution is optimized to match real-world usage scenarios with precise parameter tuning.
The panel adopts a Real RGB super-pixel arrangement that eliminates the pixel-sharing issue found in traditional OLEDs. Each RGB sub-pixel lights up independently, which helps deliver sharp edges, improved clarity, and reduced power consumption.
The display’s luminous efficiency reaches 82.1 cd/A, allowing it to achieve high brightness levels while maintaining better power efficiency. TCL CSOT claims the screen offers cleaner and more transparent color reproduction. The 1-120Hz LTPO refresh rate adjusts dynamically to balance visual fluidity with energy savings.
This is not the only Xiaomi device using a TCL CSOT panel. The Xiaomi 17 Pro and 17 Pro Max previously adopted displays from the same supplier. Xiaomi and TCL CSOT have maintained a strategic partnership since 2017, extending beyond smartphones to tablets, in-vehicle displays, and other product categories. In 2021, both companies established a joint innovation laboratory, which was further expanded with a Phase II facility in July 2025.
In related news, TCL has announced the Note A1 tablet featuring a color NXTPAPER display and AI-powered functions, and has also launched the P7 Ultra, its first smart health air conditioner based on the OpenHarmony platform.
