BOE Introduces TADF Technology into OLED with High Color Gamut and Advantages

TapTechNews September 13th news, according to BOE Innovation Center, BOE has successfully introduced TADF (Thermally Activated Delayed Fluorescence) sensitized high-color gamut technology into dual-stack tandem OLED, with the advantages of both low power consumption and long lifespan.

BOE has displayed a 6.55-inch exhibit at the 2024 BOE Global Innovation Partners Conference held on September 5th, and its BT.2020 color gamut coverage rate reaches 95%, which is higher than that of LG Display's W-OLED panel (70%) and Samsung Display's QD-OLED panel (90%).

TapTechNews note: BT.2020 is a standard specifically formulated by the ITU International Telecommunication Union for ultra-high-definition display and is currently the widest color gamut standard in the world.

BOE stated that the TADF sensitized high-color gamut technology adopts a combination scheme of deep green super fluorescence + deep red phosphorescence. The key-layout deep green super fluorescence retains the advantage of 100% internal quantum efficiency of TADF through TADF sensitized deep green fluorescence and efficient long-range energy transfer, making up for the shortcoming of the luminous efficiency of fluorescent materials; at the same time, it gives full play to the high color purity advantage of deep green fluorescent materials to further improve the color gamut and achieve a BT.2020 color gamut coverage rate of more than 95%, ranking at the leading level in the industry.
