LG Display announces viability of ‘Dream OLED’ tech – but I wouldn’t count on seeing it in the next generation of OLED TVs

• LG Display announced “commercialization level” performance of a blue phosphorescent OLED panel
• The new panel is a hybrid fluorescent/phosphorescent design that consumes about 15% less power than typical OLED displays
• The new tech 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 today announced it has successfully verified the “commercialization level” performance of blue phosphorescent OLED panels.

The announcement comes eight months after LG Display partnered with OLED technology company Universal Display Corporation on the development of blue phosphorescence, a necessary next step in creating a “Dream OLED” display.

According to LG Display’s release, the company was able to make the technology mass production-ready using a “hybrid two-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, which use a blue fluorescent layer paired with red and green phosphorescent layers.

The issue with using a fluorescent layer in OLED panels is that it provides only 25% light efficiency compared to a phosphorescent layer, which provides 100% light efficiency. LG Display’s hybrid approach changes things up in “combining the stability of fluorescence with the lower power consumption of phosphorescence.” By doing so, it “consumes about 15% less power while maintaining a similar level of stability to existing OLED panels,” according to the company.
