LG Display: Alle ny-producerede OLED-paneler har nu 'EX' teknologi

24 Nov 2022 | Rasmus Larsen |

LG Display har fuldført overgangen til det mere energieffektive OLED-panel med EX-teknologi, også kendt som OLED EX.

Mere end 20 mærker indkøber OLED TV-paneler fra LG Display, herunder LG Electronics, Hisense, Sony, Panasonic og Philips. Nogle af disse partnere skilter med 'OLED EX' i deres nyeste TV-modeller, mens andre mærker afviser at kommentere eller bruger egen branding.

Den sydkoreanske producent af skærmpaneler fuldførte ved udgangen af andet kvartal 2022 overgangen til OLED EX. Dermed er alle nyproducerede paneler OLED EX. Selskabet har tidligere hævdet, at OLED EX har op til 30% højere lysstyrke end traditionelle OLED-skærme.

- "LG Display has integrated its EX Technology into all OLED TV displays manufactured at its OLED production plants in Paju, South Korea, and in Guangzhou, China, since the second quarter of 2022," skriver LG Display til Flatpanels.

OLED EX er ikke eksklusiv

Det betyder ikke, at alle OLED TV på forbrugermarkedet bruger EX på nuværende tidspunkt. TV-skærme kan være samlet inden skiftet eller bruge paneler fra lagrene – især billigere OLED TV-modeller. Det betyder dog, at OLED EX-paneler i nærmeste fremtid vil blive anvendt i alle mærker undtagen Samsung. Det nye panel er ikke forbeholdt bestemte partnere. Samsung S95B og Sony A95K er bygget på Samsung Displays QD-OLED panel, som er det eneste alternativ til LG Displays WOLED (EX) paneltype.

Hvad er OLED EX?

LG Display forklarer (fra annonceringen i december 2021): The EX Technology applied to the OLED EX displays combines deuterium compounds and personalized algorithms to enhance the stability and efficiency of the organic light emitting diode, thereby improving the overall display performance. Thanks to EX Technology, OLED EX displays unlock new levels of picture accuracy and brightness to accurately deliver exquisite, realistic details and colors without any distortion – such as the reflection of sunlight on a river or each individual vein of a tree leaf.  Deuterium compounds are used to make highly efficient organic light-emitting diodes that emit stronger light. LG Display has successfully converted the hydrogen elements present in organic light emitting elements into stable deuterium and managed to apply the compounds to OLED EX for the first time. Deuterium is twice as heavy as normal Hydrogen, and only a small amount exists in the natural world – as only one atom of Deuterium is found in about 6,000 ordinary Hydrogen atoms. LG Display has worked out how to extract deuterium from water and apply it to organic light-emitting devices. When stabilized, the Deuterium compounds allow the display to emit brighter light while maintaining high efficiency for a long time.

In addition, thanks to LG Display’s very own 'personalized algorithm' based on machine learning technology, OLED EX is more in control of its own device. The algorithm predicts the usage amount of up to 33 million organic light-emitting diodes based on 8K OLED displays after learning individual viewing patterns, and precisely controls the display’s energy input to more accurately express the details and colors of the video content being played.
