Abstract
Recently, LG Display completed the "EX Technology" development and is prioritizing technological innovation. This technology includes deuterium technology and personalization algorithms, which increase screen brightness (luminance) by 30% compared to existing OLEDs while producing more accurate and natural colors. In this paper, we will describe how deuterium technology can improve the lifetime of OLED products and the degradation mechanism of deuterated materials. By replacing the C‐H bond with a C‐D bond, isotope species exhibit electrochemical stability, leading to a longer device lifetime.
