Samsung Display is reportedly making major advancements in OLED technology, particularly in the creation of blue phosphorescent OLED (PHOLED) components, according to claims from the Korean media outlet The Elec.
Samsung May Shift to Blue PHOLED for Future Foldables
Presently, blue OLEDs employ less efficient fluorescent materials with just 25% efficiency, whereas red and green OLED components in displays use phosphorescent materials with 100% internal luminous efficiency. Samsung wants to reduce the overall power consumption of OLEDs by swapping out these less efficient blue fluorescent elements with more effective blue light-emitting technologies.
This new material set is aimed for a second half 2025 introduction, according to market research company UBI Research. It is anticipated to be a component of Samsung Display’s flexible OLED material set M15. At first, blue PHOLED materials were supposed to be available by the middle of 2024. However, because to developmental obstacles, the schedule has been extended to the second half of 2025.
In comparison to the materials used in earlier sets like M11 and M13, the new blue PHOLED materials are expected to reach a luminous efficiency of at least 55% and a brightness efficiency of over 65%.
Samsung’s Galaxy Z Fold 7 and Flip 7 may be the first gadgets to use the new blue PHOLED technology in 2025, according to rumors, as reported by Sammobile. Its application in common products may be impacted by durability problems, as this information is currently unverified. The life of the blue PHOLED materials now in development is only half that of blue fluorescent materials.
Although switching to blue PHOLED might result in a large reduction in power usage, there are still concerns about the materials’ lifespan. Notwithstanding these difficulties, the OLED industry views Samsung’s development of blue PHOLED technology as a significant accomplishment.
