The next generation of OLED TVs could be significantly brighter thanks to US company Universal Display Company, which claims to have solved a 20-year-old puzzle: how to mass-produce blue phosphorescent material.
You see, today’s best OLED TVs are forced to use two types of emitting material: phosphorescent (for red and green light) and fluorescent (for blue). The problem is that fluorescent material is very inefficient – only about 25 percent of the power ends up as light.
Using red, green, and blue phosphors has always been the goal, as it could deliver up to 100 percent efficiency, but refining and commercializing the technology has proven impossible…until now (via flat panel hd).
“UDC expects to meet target specifications for phosphorescent blue by the end of the year,” said Mike Hack, vice president of Universal Display, according to the Korean newspaper. ETNews.
If so, UDC, which currently supplies TV titans like LG and Samsung, could start shipping blue ‘PHOLED’ materials in early 2024. And since TV makers usually launch their flagship models in March/April, could we will review the very first blue PHOLED TV in late 2024.
UDC has not disclosed how the breakthrough came about and questions remain about the longevity of blue PHOLED panels. Still, it looks like the future of TV is getting brighter and brighter.
Meanwhile, LG Display is taking its own steps. Earlier this year it emerged that the Korean giant wants to increase the brightness of its OLED TVs by 20 percent using microlens technology – a thin transparent layer containing thousands of tiny lenses that can be added to existing OLED panels. The technology is expected to make its way to TV sets as early as 2023 and could be a major talking point at CES 2023 in January.
