Samsung Electronics is expected to launch its flagship Galaxy S25 series in early 2025. Reports indicate that Samsung Display (SDC) will supply OLED panels using a material combination known as "M13."
According to South Korea's ET News, industry sources have revealed that SDC has begun ordering materials and components for Galaxy S25 OLED production. Both Samsung and SDC are reportedly utilizing the M13 material combination for the upcoming flagship series.
OLED technology employs organic materials to produce colors, with these materials emitting light independently when powered, earning them the designation of self-emissive displays. The structure consists of a light-emitting layer and auxiliary layers, where dopants in the light-emitting layer generate red (R), green (G), and blue (B) light, while prime materials enhance brightness efficiency. Additional auxiliary materials, including the hole transport layer (HTL) and electron blocking layer (a-ETL), facilitate the light emission process.
Reportedly, the light-emitting layer materials for the Galaxy S25 OLED will be supplied by companies including DuPont, UDC, DS Neolux, Samsung SDI, Merck, and SFC. Specifically, DuPont, UDC, and DS Neolux will provide materials for the red spectrum, while Samsung SDI and Merck will handle the green spectrum. SFC and Idemitsu Kosan will supply the blue spectrum.
LG Chem will provide an a-ETL designed to improve the brightness efficiency of blue components, while DS Neolux will supply HTL along with red prime materials.
Notably, the OLED panels utilizing the M13 material combination were already employed in the flagship Galaxy S24 series, launched in the spring of 2024. This indicates Samsung plans to continue using OLEDs with this material combination for the Galaxy S25 series.
Industry trends have evolved in recent years, with smartphone manufacturers like Apple and Samsung choosing to develop new panels every two years rather than annually. This change is believed to be influenced by factors such as enhanced panel performance and market saturation in the smartphone sector.
The Galaxy S25 series is expected to launch in the first quarter of 2025, comprising the standard Galaxy S25, the larger Galaxy S25 Plus, and the high-end Galaxy S25 Ultra. These models will feature screen sizes of 6.16 inches, 6.66 inches, and 6.86 inches respectively, all featuring low-temperature polycrystalline oxide (LTPO) technology.
