Samsung May Shift to Blue PHOLED for Future Foldables

Currently, red and green OLED components in displays utilize phosphorescent materials with a 100% internal luminous efficiency, while blue OLEDs use less efficient fluorescent materials with only 25% efficiency. Samsung’s goal is to replace these less efficient blue fluorescent materials with more effective blue light-emitting materials, which could potentially lead to a reduction in overall OLED power consumption.

Market research firm UBI Research reports that this new material set, expected to be part of Samsung Display’s flexible OLED material set M15, targets a launch in the second half of 2025. Initially, expectations were set for the introduction of blue PHOLED materials in mid-2024. However, the timeline has been pushed to the second half of 2025 due to developmental challenges.

The new blue PHOLED materials are projected to achieve a luminous efficiency of at least 55% and a brightness efficiency of over 65% compared to the materials used in previous sets like M11 and M13.

There is speculation, as reported by Sammobile, that Samsung’s Galaxy Z Fold 7 and Flip 7 might be the first devices to adopt the new blue PHOLED technology in 2025. However, this information is still unconfirmed, and concerns about durability may impact its use in mainstream devices. The blue PHOLED materials under development have a lifespan that is only 55% of that of blue fluorescent materials.

While the transition to blue PHOLED has the potential to significantly reduce power consumption, the longevity of these materials remains a concern. Despite these challenges, Samsung‘s advancement in blue PHOLED technology is seen as a major achievement in the OLED industry.
