In the world of OLED panels, there are two main types of OLED materials: fluorescent and phosphorcent. Historically, it has been the easiest to work with fluorescent OLED, but it is much less efficient than phosphorous OLED, which is why, over the years, the performance industry has been trying to develop the technique required to create a 100% phosphorcent OLED (fold) panels. And when we are still not there, LG Display says that it has crossed a major milestone in that journey, Verify – For the first time all three primary OLED colors (red, green and blue) are produced from pholed materials in a format that is viable for mass production.
In principle, a 100% Pholed panel will demonstrate 99% efficiency, almost all energy is being converted into light, hardly with any heat. The pholed technique of the LG display, which is based on a hybrid two-design tendom OLED structure, does not reach this peak of performance. The company uses fluorescent blue OLED in the lower stack, adding the blue fold to the top stack.
The company is only claiming 15% energy savings on panels that use fluorescent blue OLED, but it is still tangible proof that one day folds can meet their scaffolding expectations.
The LG display is set to display its new Blue Pholed Panels at SID Display Week 2025 in San Jose, California on 11 May. For now, new panels are for small and medium -sized applications such as smartphones and tablets. Portable, battery-operated devices, especially for any energy savings, which consumes most power-is a welcome change.
The race to commercialize blue folds began in 2023, when the Universal Display Corporation (UDC) announced that it successfully created a blue phosphorious OLED content that could meet the demands of commercial mass production. At that time, no company had officially signed the process to work with the UDC, but it was widely believed that both Samsung display and LG display were considering it.
In 2024, LG Display announced that it would begin working with the UDC on the project – which was eight months ago. In short -term, the goal will be to prove that these new panels meet the promised benefits. For a longer period, it will be interesting to see if the LG display can develop a pirate panel that uses 100% pholed materials, and if it can scale the technique until the size of today’s OLED TVS.
In the size of a TV, energy efficiency is less important that reduction in heat. An OLED panel that drives coolers can run bright, and theoretically OLED can maintain that brightness for a long time, without aging. The 100% Pholed displays may prove to be capable as their QLED counterparts in brightly burnt rooms, one of the few areas where QLED continues to enjoy a profit on OLED.
