A global shortage of memory semiconductors is triggering a ripple effect across the tech industry, causing production setbacks in smartphones and casting a dark shadow over the Organic Light-Emitting Diode (OLED) sector.
Japan's Dai Nippon Printing (DNP) recently reported that the chip shortage during the first quarter (the fourth quarter of Japan's 2025 fiscal year) led to a drop in smartphone production. This downturn directly impacted DNP's “Digital Interface” division, which handles Fine Metal Mask (FMM)--a critical component in OLED manufacturing. The division's quarterly revenue tumbled to 900 million yen, down significantly from 1.47 billion yen during the same period last year.
Company officials explained that despite growth in large-scale metal masks for 8th-generation glass substrates, the overall performance declined as the semiconductor crunch forced smartphone manufacturers to scale back their assembly lines. FMM is an essential high-precision component used to deposit organic materials onto display pixels; DNP currently holds a near-monopoly in the global FMM market, making its performance a bellwether for the entire OLED industry.
South Korean display giants Samsung Display and LG Display are also on high alert. While they are somewhat insulated compared to Chinese competitors due to their focus on high-end flagship panels, they are not immune to the broader slump in demand. According to market research firm UBI Research, OLED panel shipments for smartphones reached 190 million units in Q1 2026--a 12% drop year-over-year. For South Korean manufacturers specifically, shipments fell by 7%.
Adding to the industry's woes is the intensifying pressure from smartphone makers to slash panel prices, particularly for mid-to-low-end models. This “price squeeze” is being felt throughout the entire supply chain, from panel manufacturers to material and component suppliers.
“Price pressure from panel makers isn't new, but the intensity this year is unprecedented, especially since raw material costs skyrocketed last year,” said an industry source from the materials sector. “While high-value premium products offer some breathing room, we are often supplying components for mid-range smartphones at a loss just to maintain the volume.”
