Samsung Electronics Not to Use QD Panels in 2021

Samsung Display will supply quantum dot (QD) TV panels to Chinese companies ahead of Samsung Electronics as the Korean TV giant will not use QD panels in 2021.

The QD panel or the QD-OLED panel is a flagship display that Samsung Display will produce after deciding to withdraw from the LCD business. Samsung Electronics vice chairman Lee Jae-yong announced in October 2019 a plan to invest about 13 trillion won to build a QD panel production line at Samsung Display’s Asan plant in South Chungcheong Province.

Chinese TV manufacturer TCL has decided to receive QD panels from Samsung Display in the first half of next year, parts industry insiders said on Sept. 15. Samsung Display utilizes blue OLEDs as self-illumination devices for QD panels to be supplied to TCL. The Chinese TV producer is planning to introduce a 65-inch TV model based on a QD-OLED panel for the first time at the IFA in Germany in September 2021.

TCL sells the largest number of TVs in the world among Chinese companies. TCL ranked second in terms of TV sales (5.76 million units) after Samsung (8.62 million units) in the second quarter of 2020, market research company Omdia said.

According to Omdia, Samsung Electronics is planning to receive about 18 percent of LCD TV panels it needs this year from CSOT, a China-based display producer owned by TCL, Century Science & Technology Investment and Samsung Display.

Samsung Electronics' VD Division in charge of the TV business has no plans to use QD panels for the time being, an industry insider said. This is because QD-OLED panels are a type of OLED panels that Samsung Electronics concluded are not suitable for production of large TVs.

In fact, Samsung Electronics introduced OLED TVs in 2012 but closed down its OLED TV business. Since then, it has maintained its position that OLEDs emit light as organic materials, so they cannot avoid burn-in or visible marks that are left on the screen, when used for a long period of time. Currently, Samsung Electronics is focusing its capabilities on developing microLED TVs based on quantum dots which are relatively free from the burn-in problem.

Samsung Display is planning to continue its QD panel business even if Samsung Electronics does not purchase QD panels. This is because Samsung Display cannot make profits in the LCD business. Samsung Display reportedly showed prototypes of QD-OLED panels to Sony and Panasonic in Japan recently.

"Currently, QD-OLED panels have not reached the level of brightness that Samsung Electronics desires," said Lee Choong-hoon, a former Samsung researcher and CEO of UBI Research. "It will be difficult for Samsung Electronics to purchase them because it values display brightness."
