LG introduces OLED EX display using deuterium to enhance brightness up to 30%

LG has unveiled its latest display technology, the OLED EX, which implements LG Display’s deuterium and personalised algorithm-based ‘EX Technology’, enhancing brightness up to 30% compared to conventional OLED displays.

Derived from ‘Evolution’ and ‘eXperience’, the name ‘OLED EX’ represents the company’s goal of providing customers with new experiences through its ever-evolving OLED technology.

OLED EX is the result of knowledge and knowhow the company has gained over almost 10 years of OLED display development. The EX Technology applied to the OLED EX displays combines deuterium compounds and personalised algorithms to enhance the stability and efficiency of the organic light emitting diode, improving the overall display performance.

Deuterium compounds are used to make highly efficient organic light-emitting diodes that emit stronger light. LG Display found a way to convert the hydrogen elements present in organic light emitting diodes into stable deuterium and apply the compounds to OLED EX.

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. The company has discovered a method of extracting deuterium from water and apply it to organic light emitting devices. When stabilised, the deuterium compounds allow the display to emit brighter light while maintaining high efficiency for a long time.

Paired with LG Display’s personalised algorithm based on machine learning technology, OLED EX has much more control. 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 display the details and colours of the video content more accurately.

The new OLED EX technology has also led to reduced bezel thickness from 6mm to 4mm based on 65” OLED displays to create a more immersive viewing experience.

The company has also revealed its plans to integrate OLED EX technology into all OLED TV displays manufactured at its OLED production plants in Paju, South Korea and in Guangzhou, China starting Q2 2022.

“Despite the global TV market experiencing a 12% decline this year, we still observed a 70% growth in OLED sales,” said Dr. Oh Chang-ho, executive vice president and head of the TV Business Unit at 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.”
