Samsung Display aims to transition to blue phosphorescence OLED (PHOLED) in its mobile OLED panels by the second half of 2025, according to UBI Research.
Switching from blue fluorescent OLED with 25% internal luminous efficiency to blue phosphorescent OLED (PHOLED) with 100% internal luminous efficiency can significantly improve energy efficiency, leading to lower power consumption, increased brightness, or a combination of both.

The primary supplier of OLED materials, Universal Display (UDC), has repeatedly stated that blue PHOLED is on track for commercialization in 2024. However, the decision to apply it to OLED TV and monitor panels lies with the display maker such as LG Display and Samsung Display, and consequently with consumer electronics makers to adopt these new panels for use in consumer products.
Late 2025 or 2026?
According to the report, Samsung Display is aiming to transition to PHOLED in its mobile OLED panels, commonly known as AMOLED, by the second half of 2025, with foldable phones being among the first devices to benefit.
- "The red and green phosphorescent materials to be used for B1 will be applied to the materials that Samsung Display is developing for the flexible OLED material set M15. The target time for applying blue phosphorescent is the second half of 2025," Deputy Director of UBI Research, Yoon Dae-jeong, said at an industry seminar in South Korea last week according to Korean newspaper The Elec.
Samsung had originally hoped to introduce blue PHOLED by the second half of 2024, he said.
Yoon did not provide specific insights into Samsung Display's plans for QD-OLED panels used in TVs and monitors.
UBI Research estimates that the lifetime of blue PHOLED is only 55% compared to the blue fluorescent OLED used in panels for Samsung's Galaxy S21 Ultra and Apple's iPhone 13.
Samsung Display supplies OLED panels to a long list of other companies, including Apple, Samsung Electronics and Sony.
