On August 22, South Korea's ETNews reported that LG Display, a manufacturer of Pure White OLED (WOLED) panels for TVs, displays and other devices, has developed a new OLED panel, also known as the “OLED dream panel” by South Korea. ETNews First successful use of blue PHOLED material
In general, the light produced by OLED displays is produced by two types of materials: fluorescent and luminescent (PHOLED), which is usually used in RGB pixels. Different materials produce light, i.e. red (R) and green (B) pixels use existing phosphors (PHOLED), while blue (B) pixels use fluorescent.
2022 It is noteworthy that the breakthrough achieved by OLED technology, after QD-OLED and microlens array (MLA), will be the transition from fluorescent to phosphorescent (PHOLED) with blue pixels. This will increase the efficiency of blue light from 25% to 100%, which will lead to the OLED screen including 3 RGB colors, which reduces power consumption by up to 25%, or in simple terms, helps make the screen brighter.
LG Display says it has successfully developed an OLED panel using PHOLED Blue technology. A full-scale evaluation of the production efficiency will be conducted this year. It revealed that it has overcome the challenge by using a hybrid structure, which involves stacking two layers of light-emitting OLEDs by combining fluorescent and phosphorescent OLEDs (PHOLED Blue) to achieve a lifespan similar to current OLEDs.
However, earlier this month, it was reported that blue PHOLED developer Universal Display (UDC) has postponed the release of blue PHOLED material from 2024 to 2025, so mass production of blue PHOLED-based OLED displays will also require cooperation with UDC.
