LG Displays 2022 'OLED EX' panel har op til 30% højere lysstyrke

29 Dec 2021 | Rasmus Larsen |

Forud for CES 2022 har LG Display afsløret 'OLED EX', som er næste generation af OLED med højere lysstyrke. Produktionen starter i 2022.

OLED TV i 2022

OLED EX er et akronym for Evolution og eXperience, ifølge LG Display. Med en kombination af deuterium (tung brint) og en ny panel-algoritme kan lysstyrken øges med "op til 30 procent i forhold til konventionelle OLED-skærme". OLED EX-teknologien implementeres i alle OLED TV paneler produceret fra 2. kvartal 2022 på begge af LG Displays fabrikker i hhv. Sykorea og Kina. - "LG Display plans to strengthen its leadership and product competitiveness in the large-sized OLED business by integrating OLED EX technology into all OLED TV displays manufactured at its OLED production plants in Paju, South Korea, and in Guangzhou, China, starting from the second quarter of 2022," annoncerede LG Display. Det indebærer, at vi får mere lysstærke OLED TV fra flere producenter i 2022 – LG, Sony, Panasonic, Philips og andre. 2022 OLED-panelet får også tyndere rammer (4mm i forhold til 6mm).

OLED EX

LG Display er den eneste leverandør af OLED TV-paneler på verdensplan, men rygtet vil vide, at Samsung træder ind på markedet i 2022 med QD-OLED. LG Display startede masseproduktion af OLED TV-paneler i 2013 og har sidenhen solgt over 20 mio. paneler verden over. - "Despite the global TV market experiencing a 12 percent decline this year, we still observed a 70 percent growth in OLED sales," sagde Dr. Oh Chang-ho, EVP & chef for TV Business Unit hos LG Display. "With our new OLED EX technology, we aim to provide even more innovative, high-end customer experiences through the evolution of our OLED technology, algorithms and designs."

Hvad er OLED EX?

LG Display forklarer: 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.
