CEO of Samsung Display confirms that Samsung is “developing technology to prepare large quantum dot organic light emitting diodes”, according to a reports from Korean media. The advanced OLED TVs will offer advantages over LG’s OLED TVs

The confirmation came at the International Information Display Exhibition (IMID) held at COEX in Seoul, Korea, in response to a reporter’s question about so-called QD-OLED TVs, short for Quantum Dot OLED TVs.

- "We are developing technology to prepare large quantum dot organic light emitting diodes (QD-OLEDs)," said Lee Dong-hoon, CEO of Samsung Display.

The rumor about Samsung developing QD-OLED display technology first emerged in early 2018. Samsung Electronics, who is pushing quantum dot enhanced LCD TVs, attempted to shoot down the rumor but it continued to circulate. It is now clear that it is Samsung Display – Samsung’s display production arm – who is developing the QD-OLED display technology.

CEO Lee Dong-hoon emphasized that Samsung Display is developing large-size QD-OLED panels for TVs and that development is proceeding smoothly.



By combining quantum dots with OLED, the OLEDs can effectively serve as emitters that excite the quantum dots to create very saturated colors. Samsung is believed to be focusing on an approach with blue OLED emitters behind a layer of quantum dots. QD-OLED will feature the same advantages as today’s OLED TVs, including deep blacks, but may deliver higher brightness and a wider color gamut – possibly also lower production costs.

Samsung sees QD-OLED as a potential competitor to LG’s OLED technology, according to Korean media. The company tried to commercialize RGB OLED TVs in 2012-2013 but had to abandon the project due to low production yields. Plan B involved launching quantum dot enhanced LCD TVs but the world’s leading TV maker continues to lose ground in the premium TV segment to manufacturers of OLED TVs. Samsung is also developing TVs based on microLED display technology.

Korean media previously reported that Samsung is hoping to start pilot production of QD-OLED displays in the second half of 2019.
