According to a South Korean market research firm, Quantum Dot Organic Light Emitting Diode (QD-OLED) display panels are expected to account for less than 10% of the total large-size OLED panel shipments through 2024.

Market research firm UBI Research issued a statement last week saying Samsung Display will only invest in enough materials to support output of up to 30,000 QD-OLED substrates per month at its updated Asan factory. At the same time, the company will begin producing at an additional line, quantum dot nanorod emitting diode (QNED) displays.

According to South Korean business site The Elec, UBI expects 2021 large-size shipments of WRGB-OLED panels, produced solely by LG Display, to reach 4.69 million units, compared as Samsung Display churns out 360,000 units of QD-OLED panels. In 2024, 9.77 million WRGB-OLED panels will be shipped while QD-OLED shipments reach 830,000 units.

LG’s WRGB-OLED technology uses a self-emitting white light with RGB diodes to product color, while Samsung’s QD-OLED will use blue-light emitting diodes topped with a sheet of Green and Red quantum dots to produce very bright full color levels.

QNED uses blue-light-emitting nano-sized cylinders and thin film transistors (TFT) topped with a quantum dot color filter.

The Elec reported UBI’s research saying QD-OLED will account for only around 10% of materials purchased for large-sized OLED. In 2021. QD-OLED materials cost will rise from $20.8 million to $41.1 million in 2024. In contrast, LG’s WRGB-OLED emissive materials costs will rise from $240 million in 2021 to $282.8 million in 2024.

UBI Research also said there is little chance that LG Display will adopt inkjet printing methods due to limited man power and investment budgets. Instead, LG Display will continue to invest in a “deposition OLED method” as it moves forward with a 10.5th generation line for improved panel quality and production efficiency, the research firm said.

LG Display working to startup production at a 10.5th generation OLED line in Paju, South Korea, but the initial launch plan has been delayed to an unspecified time, The Elec reported. LG Display did not return our requests for confirmation.

The Elec said the reason for the delay was a lower than expected operation rate of LGD’s 8.5th generation OLED line at Guangzhou, China.
