30.12.2021 - LG Display annuncia la tecnologia OLED EX per i televisori OLED di next gen

L'argomento è destinato ad essere approfondito a breve in occasione del CES 2022, tuttavia LG Display ha annunciato la tecnologia OLED EX destinata a diventare la feature primaria dei suoi televisori OLED di nuova generazione.

In accordo a LG Display, la tecnologia OLED EX (Organic Light Emitting Diode Evolution eXperience) rappresenta uno step evolutivo rispetto alle attuali soluzioni OLED poichè migliora la qualità dell'immagine, ed in particolare incrementa fino al 30% la luminosità del pannello.

Dal punto di vista tecnico, LG Display ha reso noto di aver scoperto come deuterio dall'acqua (per fissare le idee, un atomo di deuterio si trova in circa 6.000 atomi) e utilizzarlo per la fabbricazione di diodi organici a emissione di luce altamente efficienti.

I diodi basati su deuterio, prosegue LG Display nel corso del comunicato stampa pubblicato di recente, non soltanto emettono luce più brillante rispetto ai dispositivi impiegati negli OLED tradizionali, ma conservano una elevata efficienza per lungo tempo.

A beneficiare dei diodi a deuterio sono in particolare la resa del colore nero "perfetto", l'accuratezza e l'intensità cromatica degli altri colori e, dulcis in fundo, il tempo di risposta estremamente ridotto.

Press Release

LG Display, the world's leading innovator of display technologies, unveiled today 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 innovative 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. OLED.EX is the result of the unparalleled knowledge and knowhow the company has gained over nearly ten years of developing OLED displays, created to deliver the most lifelike images that transcend the limitations of a conventional display.

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.

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 and premium design.

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.

In 2013, LG Display's first year of starting mass-production of OLED TV displays, the company sold 200,000 units and by early last year recorded accumulated sales of 10 million units. In the two years since then, the company's accumulated sales have doubled to surpass 20 million units globally.

"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."
