According to a new report from The Elec, South Korea, Samsung Display is making great progress in OLED display technology, especially in the development of blue light-emitting OLED (PHOLED) components.
Currently, the blue fluorescent solution that Samsung Display uses for its AMOLED panels has an internal luminous efficiency of 25%, while the company's red and green PHOLEDs have a luminous efficiency of 100%. By replacing blue fluorescent OLEDs with PHOLEDs, Samsung Display can reduce the overall power consumption of the display panel.
According to the report, the new blue PHOLED material is predicted to achieve a luminous efficiency of at least 55% and 65% better than previously used materials.
Market research firm UBI Research reports that this new set of materials is expected to launch in the second half of 2025. Sources from Sammobiles said that the first Galaxy phones to use them are the Galaxy Z Fold7/ Z Flip7. However, this information is yet to be confirmed and durability concerns may affect its use in Samsung's flagship devices. Blue PHOLED materials are being developed that have a lifespan that is only 55% that of blue fluorescent materials.
Overall, while the transition to green PHOLEDs has the potential to significantly reduce power consumption, the longevity of these materials remains a concern. Despite these challenges, Samsung's advancement in green PHOLED technology is considered a major achievement in the OLED industry.
