After proclaiming earlier this month that it would be the first to mass produce blue PHOLED displays, which it calls “dream OLED,” LG Display has now unveiled the first of its blue PHOLED panels. This week, the company showcased the dream OLED panel for the first time at SID Display Week, in addition to its other panels types. Footage of the new panel, which the company claims is the result of 20 years of research, was captured in a video taken by FlatpanelsHD at the expo. The 13-inch panel, which LG Display says will be utilized in IT devices, appears at the 1:07 mark in the video above.
“With significantly greater luminous efficiency than all OLED generations to date, blue phosphorescent OLED is the result of LG Display’s implementation of a newly developed hybrid two-stack Tandem OLED structure,” said LG Display. “By featuring blue phosphorescence in the upper stack of this structure, the IT panel exhibited at SID Display Week 2025 consumes about 15% less power than existing OLED panels.”
The following was originally published May 5, 2025:
LG Display is claiming it has won the blue PHOLED arms race, with the company announcing it is the first in the world to have a blue PHOLED panel ready for mass production. The mass production of blue PHOLED displays is the result of two decades of R&D, says LG, pointing to the recent breakthrough of tandem-stack OLED displays as the final piece of the puzzle needed to produce ‘dream OLED’ on a large scale. Universal Display was originally reported to have its panels ready by the end of last year, but a commercial launch was ultimately delayed. LG and Samsung were also reported to be on the cusp of blue PHOLED production, and it seems that LG has struck first.
“…Achieving blue phosphorescence has remained a major challenge even more than 20 years after the commercialization of red and green phosphorescence. This is due to blue, among the three primary colors, having the shortest wavelength and demanding the greatest energy,” reads LG’s press release. “LG Display has solved this issue by using a hybrid two-stack Tandem OLED structure, with blue fluorescence in the lower stack and blue phosphorescence in the upper stack. By combining the stability of fluorescence with the lower power consumption of phosphorescence, it consumes about 15% less power while maintaining a similar level of stability to existing OLED panels.”
The company says it will be unveiling its new panel at SID Display Week 2025 in California, beginning May 11. Further specifications of the panel, including a production timeline, is expected to be revealed at the event.
