Samsung Display’s mobile panels could become fully phosphor-based in the second half of 2025. PHOLED (Phosphorescent OLED – Phosphorescent organic light emitting diodes), which should not be confused with POLED (Plastic OLED), is a material that Samsung Display currently uses for the green and red pixels of AMOLED panels. A new report indicates that Samsung is working on phones with PHOLED screens.Samsung moves forward with PHOLED display
According to UBI Research, Samsung, which uses PHOLED for green and red pixels, is also making improvements for blue pixels, albeit with a slight delay. According to reports, Samsung will reach the capacity to fully use PHOLED panels in the second half of 2025. Of course, it is unclear for now whether foldable phones will be the first to use blue PHOLED, but theoretically phones such as the Galaxy Z Fold 7 and Galaxy Z Flip 7 could be the first devices to benefit from this technology. However, there are some durability concerns that may prevent Samsung from using PHOLED for mainstream devices.
What are the benefits of PHOLED?
Samsung Display’s current blue fluorescent solution for AMOLED has an internal light efficiency of 25%, while the company’s red and green PHOLEDs have an efficiency of 100%. Samsung Display can reduce overall power consumption by replacing blue fluorescent OLEDs with PHOLEDs. On the other hand, the blue PHOLED materials currently under development are said to have a 55% lifespan compared to blue fluorescent materials.Because of this durability concern, UBI Research says Samsung Display’s first implementation of blue PHOLED may not become mainstream. Regardless, UBI Research believes that Samsung Display will continue to develop blue PHOLED; Because being the world’s first manufacturer capable of mass producing AMOLED panels with blue phosphorescent pixels will be a significant success for the company. In this way, it is possible to say that Samsung can create a significant source of income.
