- LG Display announced the “marketing level” performance of a blue OLED panel
- The new panel is a fluorescent/phosphorescent hybrid design that consumes approximately 15% less power than typical OLED screens
- The new technology will be demonstrated in a “small and medium panel that can be applied to IT devices, such as smartphones and tablets”
The Korean manufacturer LG Display announced today that it has successfully verified the performance of the “level of marketing” of the Blue Fosphorescent OLED panels.
The announcement occurs eight months after LG Display was associated with the technology company OLED Universal Display Corporation on the development of blue phosphorescence, a next step necessary to create a “OLED deed” screen.
According to the launch of LG Display, the company was able to prepare the mass production of technology using an “OLED structure in two -batter hybrid tandem, with blue fluorescence in the lower pile and blue phosphorescence in the upper battery”. This approach differs from previous OLED screen panels, which use a blue fluorescent layer combined with red and green phosphorescent layers.
The problem with the use of a fluorescent layer in OLED panels is that it provides only 25% light efficiency compared to a phosphorescent layer, which provides 100% light efficiency. The hybrid LG Display approach changes things in “combining the stability of fluorescence with the lower consumption of phosphorescence energy.” In doing so, “consume approximately 15% less energy while maintaining a similar level of stability to existing OLED panels,” according to the company.
LG plans to demonstrate its Blue OLED Fosphorescent Panel with two -tab tandem technology at the SID exhibition week, an event that begins on May 11, 2025 in San José, California.
Has the dream OLED TV arrive?
While LG Display’s announcement is intriguing, the OLED Blue Fosphorescent panel that plans to show in the SID exhibition week will show the technology in “a small and medium panel that can be applied to IT devices, such as smartphones and tablets.”
That means that the current iteration of technology, while mass production (LG Display says that it has “completed the commercialization verification with UDC”) remains prototype form, and is not ready for introduction on larger screens, such as the best OLED televisions.
We have been following the news about Blue Pholed, a term used for the phosphorescent layer on OLED screens, for some time, and previously reported in LG Display that “an OLED panel based on blue phosphorescence” successfully developed.
Today’s news goes further in the certification that a similar OLED screen panel is ready for stellar schedule, but this version uses a hybrid approach that still does not meet the expectations of complete light efficiency of a “dream olde”.
Meanwhile, the OLED “Four-Stack” screen panel of LG Display, a design that is not based on blue, hybrid or other phosphorescent technology, but uses separate red, green and blue elements to improve purity and impulse brightness, can be found in the impressive new LG C5 OLED, one of the best televisions that arrive so far in 2025.
We hope that this panel remains the avant -garde for OLED televisions for some time, while the new tandem tandem structure with blue phosphorescence develops for devices such as phones and tablets.
