LG Display has unveiled its newest OLED TV technology 'OLED EX'. The next-generation OLED EX display implements LG Display's deuterium and personalized algorithm-based 'EX Technology,' which helps boost the display's overall picture quality by enhancing brightness up to 30 percent compared to conventional OLED displays. The OLED EX name is an acronym of 'Evolution' and 'eXperience', which represents the company's goal of providing customers with new experiences through its ever-evolving OLED technology.
OLED displays are self-emissive by nature with their multiple millions of pixels emitting light independently without a separate backlight source. This distinctive characteristic lets OLED EX achieve the perfect black, rich and accurate color expression as well as an extremely fast response time.
Since 2013, the year it became the first to mass produce OLED TV displays, LG Display has been consistently improving its leading OLED technology. 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. For further information see the IDTechEx report on Flexible, Printed OLED Displays 2020-2030: Forecasts, Markets, Technologies.
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.
LG Display has also upgraded its designs through the new OLED EX technology. By utilizing its innovative EX Technology, the company reduced bezel thickness from the original 6 mm to 4 mm based on 65-inch OLED displays. By reducing the bezel thickness by 30 percent compared to existing OLED displays, the OLED EX display creates an even more immersive viewing experience all the while delivering a sleeker design.
LG Display plans integrate 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.
"Despite the global TV market experiencing a 12 percent decline this year, we still observed a 70 percent growth in OLED sales," said Dr. Oh Chang-ho, Executive Vice President & 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."
