OLED displays will not receive the highly anticipated, more efficient blue phosphorescent OLED this year, as Universal Display has postponed the commercial introduction beyond 2024.
OLED displays already use phosphorescent red and green OLEDs – known as PHOLEDs – but the blue OLED remains on the less efficient fluorescent type.
Switching to PHOLED for blue could lead to a 25% reduction in power consumption, according to Universal Display, the leading supplier of OLED materials. The improved efficiency could also be used to increase OLED brightness.
No longer coming in 2024
Universal Display has stated since 2022 that it was on track to commercialize blue PHOLED by the end of 2024.
However, during its second-quarter financial report, Universal Display officially postponed the launch.
- "The bottom-line is phosphorescent blue is coming. We just need some more time before commercial introduction. When it is adopted in an OLED device, we believe that the benefits will be significant for the industry, for consumers and for us," Universal Display said on its conference call.
It said that the "additional time needed will be measured in months and not years".
The first hint of the delay came when Samsung Display postponed its adoption of blue PHOLED in its OLED panels from the second half of 2024 to the second half of 2025.
One of the challenges with blue PHOLED is that its lifetime is only 55% of that of the current blue fluorescent OLED, according to UBI Research.
