LG's latest "dream OLED" display panels are now ready for mass production, sparking questions about the potential replacement of Primary RGB Tandem OLED technology.

LG Display is set to make a significant stride in the world of Organic Light-Emitting Diode (OLED) technology with the introduction of Hybrid Tandem OLED panels, also known as PHOLED, at SID Display Week 2025 in San Jose, California.

The new PHOLED panels will incorporate a high-efficiency blue phosphorescent layer and a long-lifetime blue fluorescent layer, in addition to red and green phosphorescent layers. This innovative approach aims to overcome the challenges faced in implementing a blue phosphorus layer in OLED panels due to the short wavelength of blue light and its energy demand.

LG Display has reportedly found a solution for this issue, suggesting improved OLED panel brightness and energy efficiency in the future. This development is a significant step towards achieving full RGB phosphorescence in OLED panels, a long-sought goal in the industry, often referred to as the "dream OLED" scenario.

Initially, the first devices with PHOLED panels will be small and medium-sized products like smartphones, tablets, and laptops. As more products require high definition and high efficiency, such as AI PCs and AR/VR devices, the application of blue phosphorescence technology is expected to expand rapidly.

However, the company has not yet announced which device types will first feature this new OLED technology. It is also worth noting that the upcoming Primary RGB Tandem OLED TVs are expected to have their moment in the spotlight before the potential release of PHOLED TVs.

LG Display will debut a blue phosphorescent OLED panel featuring two-stack Tandem technology at SID Display Week 2025. The market debut of PHOLED panels is anticipated to occur after the release of the Primary RGB Tandem OLED TVs, including the Philips OLED910 and Panasonic Z95B, which are scheduled for later this year.

While the exact brightness increase of PHOLED panels compared to currently available WOLED and Primary RGB Tandem OLED panels is not specified, it is known that phosphorescence has a significantly higher luminous efficiency compared to fluorescence, as it stores energy before emitting light.

As the world moves towards more energy-efficient and high-definition displays, LG Display's PHOLED technology is poised to make a significant impact. The expansion of this technology is expected to include larger displays, although LG Display has not yet explicitly mentioned PHOLED TVs.

In conclusion, LG Display's Hybrid Tandem OLED panels, or PHOLED, represent a promising development in the field of OLED technology. With improved brightness, energy efficiency, and the potential for application in various devices, this technology is set to revolutionise the display industry. Stay tuned for more updates from SID Display Week 2025.
