Samsung Display is reportedly working on introducing blue phosphorescent materials to its OLED components in order to reduce power consumption. The current red and green phosphorescent materials used in OLED have an internal luminous efficiency of 100%, while the blue fluorescent material only has an efficiency of 25%. By replacing the blue fluorescent material with phosphorescent versions, Samsung aims to increase the overall percentage and reduce power consumption.
According to UBI Research deputy director Daejeong Yoon, Samsung Display is actively developing these blue phosphorescent materials and plans to incorporate them into a set called “B1.” The materials used in B1 will be part of the flexible OLED material set M15 that Samsung Display is currently working on.
Yoon anticipates that the use of blue phosphorescence will begin in the second half of 2025. However, he notes that previous predictions for its use in foldable smartphones by mid-2024 haven’t progressed smoothly. Despite this, Samsung Display intends to utilize the material still under development, even if its lifespan is only 55% that of the fluorescent material used in M11, which was employed in the iPhone 13 series.
Additionally, Samsung aims to increase luminous efficiency by more than 65% compared to the material used in the M13 OLED material set. This set was utilized in Google’s Pixel 8 Pro and will also be employed in Samsung’s Galaxy S24 series in 2024.
Yoon predicts that Apple’s iPhone models from 2024 onwards, specifically the iPhone 16 and iPhone 17, will feature M14 as their display material. As for future cycles, odd-numbered sets will be used by both Samsung and Chinese companies, while even-numbered sets will be reserved for Apple. This two-year usage pattern suggests that it remains uncertain whether the development of blue phosphorescence will make it into iPhones until either the iPhone 16 or the iPhone 17.
If the claims regarding material set cycles and the arrival of blue phosphorescent technology in 2025 hold true, it may imply that Apple users will have to wait until the iPhone 18 in 2026 to benefit from these display changes.
