The OLED war continues, and the leading manufacturers in the industry continue to look for ways to deliver panels that are much more efficient and higher-performing. That’s why companies like LG or Samsung are experimenting to find out what kind of technology they can implement in their televisions. greatly improves brightness and efficiency And this technology is likely to be PHOLED.
Samsung has started to invest heavily in OLED technology. In fact, in addition to QD-OLED panels, we recently learned that the company is in talks with LG to get hundreds of thousands of W-OLED panels for commercialization. However, the future of OLED is to continue to increase its brightness and efficiency in panels, as well as their continuous advances in image processing, thanks to improvements in each manufacturer’s algorithms. one of the next steps could be PHOLED technology.
Light emission in OLED panels can be divided into two types: fluorescent and phosphorescent (PHOLED). Currently, OLED panels already offer phosphorescent emission in the red and green subpixels, but the blue subpixel remains fluorescent due to technical and economic limitations. Fluorescent emission uses only 25% of the emitted light, while phosphorescent uses 100% of the light, according to the manufacturer Universal Display.

Making the blue subpixel emit phosphor-like light can increase the efficiency of the panel 4 times. This is expressed by Mike Hack, vice president of Universal Display, one of the leading providers of PHOLED technology.
“We reached the initial specification target for blue phosphor devices last year, and we plan to mass-produce them from 2024. Switching blue OLEDs from fluorescent to phosphorescent can increase luminous efficiency by a factor of 4.”
Actual efficiency in televisions will depend on how this technology is used in OLED displays. LG currently makes W-OLED panels with multiple layers of material, while Samsung uses fluorescent blue OLEDs and quantum dot converters for red and green colors. The company also claimed to be working on phosphorescent light emission for green in its 2022 and 2023 OLED panels, although it is not used for quantum dot conversion.
Although from Universal Display, the production of blue phosphor OLED panels scheduled for 2024We still don’t know if this technology will come in next year’s models. The decision is solely up to manufacturers like LG, Samsung and so on.
As the latest innovation, users can now find OLED panels with MLA (microlens array) technology in LG’s new WOLED panels. Samsung has also done its homework with its QD-OLEDs. greatly improves efficiency and brightness It looks like we’ll have to wait to find out what the QD-OLED TV lineup is this year’s Instead all that PHOLED is and how these manufacturers will leverage the technology.
