LG Display introduces OLED EX, a new OLED display technology that implements deuterium and custom algorithmic design


Yesterday LG display revealed their latest OLED display technology, the OLED EX. The latest technology is to improve display quality using both custom Algorithm EX technology and the company’s deuterium technology. As a result, the display can not only improve the overall picture quality, but also improve the brightness by up to 30% compared to current OLED displays from other competitors.

The new OLED EX moniker from LG Display stands for “evolution and experience” – a goal that represents the company’s mission to offer consumers a first-class viewing experience through its innovative and evolving OLED technology.

Although the global TV market was down 12 percent this year, we still saw a 70 percent growth in OLED sales. With our new OLED EX technology, we want to offer even more innovative high-end customer experiences through the further development of our OLED technology, algorithms and designs.

The wonderful thing about OLED displays is that they are inherently self-emitting, offering several million pixels that independently emit light without the use of separate backlight sources. This technology is a special feature that enables OLED EX to achieve perfect black coloring, rich and accurate color expression and super-fast response times.

LG Display has consistently improved its leading OLED technology since integrating the technology in 2013. In the first year of mass production of OLED TV displays, LG Display sold 200,000 units. Until the beginning of last year, LG had accumulated sales of 10 million units. Currently, the company’s cumulative sales have doubled to over 20 million units worldwide.

LG Display’s OLED EX is the result of the unparalleled knowledge and expertise the company has accumulated over nearly ten years of developing OLED displays, delivering premium, lifelike images that push the boundaries of conventional standard displays.

The EX technology applied to the OLED EX displays combines deuterium compounds and personalized algorithms to improve the stability and efficiency of the organic light emitting diode, thereby improving the overall performance of the display. Thanks to EX technology, OLED EX displays open up a new level of image accuracy and brightness to deliver exquisite, realistic details and colors without distortion – such as the reflection of sunlight on a river or every single vein of a tree leaf.

LG has upgraded its previous designs with the new OLED EX technology. With its innovative EX technology, LG has reduced the panel thickness from 6 mm to 4 mm, based on the current 65-inch OLED displays. By reducing the thickness by 30% compared to standard OLED displays, the OLED EX display creates an even more impressive viewing experience while offering slimmer, high-quality designs.

Deuterium compounds are used to make highly efficient organic light emitting diodes that emit more powerful light. LG Display has successfully converted the hydrogen elements contained in organic light elements into stable deuterium and applied the compounds to OLED EX for the first time. Deuterium is twice as heavy as normal hydrogen, and only a small amount exists in nature – since there is only one atom of deuterium in about 6,000 ordinary hydrogen atoms. LG Display found out how to extract deuterium from water and apply it to organic light sources. When stabilized, the deuterium compounds allow the display to emit brighter light while maintaining high efficiency for a long time.

LG Display’s in-house “personalized algorithm”, which is based on machine learning technology, gives the new OLED EX more control over its own technology in its devices. The personalized algorithm predicts usage quantities of up to 33 million organic light-emitting diodes – all based on 8K OLED displays after learning individual visual patterns. The technology then precisely controls the power of the display to produce more accurately and express the details and colors of the video content being displayed.
