After announcing the company’s business results for the first half of this year, Choi revealed that the company’s large panel division achieved an 85 percent yield in QD-OLED panel production. He also revealed that in the first half of this year, sales of small and medium-sized panels increased by 10% over the same period of the previous year, reaching an all-time high.
After Samsung Display gradually withdrew from the LCD business, it “bet” the future on the QD-OLED technology route, and invested heavily in the layout as early as 2019. By 2025, the related investment will reach 13.1 trillion won. Samsung Display raised the QD Display project to a strategic level, hoping to lead the OLED market.
In November last year, the company produced only a 50 percent yield of QD-OLED panels in the initial stages of mass production. Sony and Dell Technologies launched TVs and gaming monitors, respectively, with QD-OLED panels from Samsung Display, and Samsung Electronics also launched QD-OLED TVs in North American and European markets.
QD-OLED is the vapor-deposited blue OLED+QD color film technology. It is a self-luminous display screen completely using QD (quantum dot) technology. It integrates the advantages of the two display technologies of QLED and OLED. It has a wide color gamut, high brightness, ultra-wide viewing angle, and other advantages.
According to Sigmaintell, the global QD-OLED TV shipment scale in 2022 will be about 700,000 units, and the future shipment scale will grow steadily. It is expected to exceed 1 million units in 2024, but the overall market size is still relatively limited.
Although demand for smartphones weakened due to inflation in the first half of this year, Samsung Display has fought a good battle in the small and medium panel market, mainly thanks to the growth in sales of foldable phones.
Market research firm DSCC said that 2.22 million foldable mobile phones were shipped in the first quarter of 2022, a 571% increase from the same period last year. In the first quarter of 2022, Samsung Display accounted for 85.9% of the foldable OLED panel market and 64.5% of the small and medium-sized OLED panel market, Omdia said.
