LG Display revealed prior to CES 2022 that it has developed a new WOLED TV panel capable of a 30% boost in peak brightness over conventional OLED displays.
The display panel manufacturing arm of LG is calling the advancement EX Technology, for Evolution and eXperience. The company explained that OLED EX utilizes rare deuterium compounds in combination with new processing algorithms to increase stability and efficiency of organic light emitting diodes to improve performance.
LG Display plans to begin implementing the new technology in OLED panels produced at its OLED panel fabs in South Korea and China beginning in the second quarter of 2022.
The 30% brightness boost will be over LGD’s “conventional” OLED panels and not LGE’s “evo” G1 series sets from 2021 that enabled a smaller brightness boost. The new EX panels will also enable 30% thinner bezels measuring 4mm compared to 6mm now.
According to the company’s statement “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.”
The company said the newly added deuterium compounds help the panels yield more 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,” the company said. “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.”
The company further explained that its new algorithm used in combination with the deuterium materials enhancement “better 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.”
The announcement comes from LGD ahead of expected announcements from rival Samsung Display on the pending introduction of its hybrid QD-OLED panel technology that is similarly expected to increase brightness, color gamut coverage, color volume and accuracy.
