In a recent report from The Elec, it has been revealed that Samsung is likely to unveil a groundbreaking blue phosphorescent OLED panel in 2025, a year later than initially anticipated. This delay is attributed to challenges in the development of the new material used for the blue sub-pixels, hindering the seamless progression of the project.
As of now, Samsung’s display technology incorporates phosphorescent green and red sub-pixels, while the blue diodes still rely on fluorescent technology. This technicality prevents them from being classified as PHOLED (phosphorescent organic light-emitting diode). The introduction of phosphorescent diodes is noteworthy for their 100% internal luminous efficiency, a substantial improvement compared to the current blue fluorescent diodes, which are limited to 25% efficiency.
The potential power efficiency boost with proper blue phosphorescent diodes is significant. However, an essential consideration emerges – the lifespan of these new diodes is reportedly only 55% of their fluorescent counterparts. This drawback raises doubts among industry experts about Samsung’s ability to integrate this technology into commercial products by the projected 2025 timeline.
Nevertheless, Samsung remains committed to research and development, aiming to be the first manufacturer to mass-produce PHOLED panels. If successful, this endeavor could provide Samsung with a substantial market advantage in the rapidly evolving display technology landscape in the coming years.
In summary, while the potential benefits of the new Samsung blue phosphorescent OLED panels are promising, challenges in material development and concerns about diode lifespan may impact the feasibility of their commercial implementation by 2025.
