LG Display is planning to apply its new technology on its OLED panels for TV to increase their luminance by 30% during the second quarter next year, when mass production will begin, the company said at a press conference on Wednesday.

The technology, called OLED.EX, uses deuterium, one of two stable isotopes of hydrogen, as well as a new algorithm and thin-bezel for improvements on the company’s TV OLED panels, LG Display said.

According to sources, the company could improve the panel's luminance thanks to a deuterium blue organic material supplied by US chemical firm DuPont.

Instead of using hydrogen like in the blue materials used for previous OLED panels, only deuterium is used for the organic material. 

The organic material is more stable and durable, which means it can handle the brightness setting on the panel increasing, sources said, while maintaining power efficiency and offering a longer life span.

Blue organic material burns out faster than the red and green organic materials used in OLED panels, so improving it is key to offering long-lasting panels.

LG Electronics’ OLED Evo TV unveiled earlier this year already used deuterium blue organic material.

LG Display applied the technology for some of its OLED panels, which it supplies to LG Electronics, manufactured at its factory in Guangzhou, China this year.

The company is planning to expand the application of the technology at its Guangzhou factory and begin applying them at its factory in Paju, South Korea, next year.

LG Display’s current OLED panels for TVs offer up to 800nit in brightness __ OLED.EX’s will likely be slightly over 1,000nit.

The company previously procured hydrogen blue organic material from Idemitsu Kosan __ but the deuterium version will be solely supplied by DuPont.

Meanwhile, besides the material change, OLED.EX also comes with an algorithm that controls how many OLED devices on the panel are used depending on consumers’ TV viewing patterns.

The technology also reduces the panel’s bezel from the previous 6mm to 4mm.

Meanwhile, LG Display declined to comment on whether Samsung Electronics will be using LG Display’s OLED panel for TVs.
