- LG -Display advertised “Commercialization Level” performance of a blue phosphorescent OLED -Panel
- The new panel is a hybrid fluorescent/phosphorescent design that consumes approx. 15% less power than typical oled screens
- The new technique will be demonstrated in a “small and medium-sized panel that can be applied to IT devices such as smartphones and tablets”
Korean manufacturer LG -Display announced today that it has successfully verified the “Commercial Level” benefit of blue phosphorescent OLED panels.
The message comes eight months after the LG Display collaborated with OLED technology company Universal Display Corporation on the development of blue phosphoruscens, a necessary next step in creating a “Dream OLED” display.
According to the release of the LG display, the company was able to make technology mass production ready using a “hybrid to-stack tandem OLED structure with blue fluorescence in the lower stack and blue phosphorescence in the upper stack.” This approach differs from previous OLED display panels that use a blue fluorescent layer paired with red and green phosphorescent layers.
The problem with using a fluorescent layer in OLED panels is that it only provides 25% light efficiency compared to a phosphorus layer layer that provides 100% light efficiency. The LG Display Hybrid approach changes things up in “combining the stability of fluorescence with the lower power consumption of phosphoruscence.” By doing it, it “consumes about 15% less power, while maintaining a similar level of stability as existing OLED panels,” according to the company.
LG is planning to demonstrate its blue phosphorescent OLED panel with two-stack tandem technology on Sid Display Week, an event that starts on May 11, 2025 in San Jose, California.
Is the dream OLED TV finally arrived?
While the LG display’s message is exciting, the blue phosphorescent OLED panel shows, it plans to show on Sid Display Week, the technology in “A small and medium-sized panel that can be used on IT devices such as smartphones and tablets.”
This means that the current iteration of the technology, while mass production ready (LG display says it has “completed commercialization verification with UDC”) remains in prototype form and is not ready for introduction into larger screens as the best OLED TVs.
We have followed the news of Blue Poled, an expression used for the phosphoric layer of OLED screens, for some time, and previously reported on LG display, which “has developed an OLED panel based on blue phosphoruscence.”
Today’s news goes on to certify that a similar OLED display panel is ready for Prime Time, but this version uses a hybrid approach that is not yet meeting the full expectations of light efficiency from a “Dream OLED.”
Meanwhile, LG Display’s “Four-Stack” OLED display panel, a design that is not dependent on blue phosphorescent tech, hybrid or otherwise, but instead use separate red, green and blue elements to improve the purity of color and increase the brightness, is found in the impressive new LG C5 OLED, one of the best tvs to arrive so far in 2025.
We expect this panel to remain leading edge for OLED TVs for some time to come, while the new hybrid two-stack Tandem OLED structure with blue phosphorescence is being developed into devices such as phones and tablets.
