LG Display has successfully developed a blue phosphorescent OLED panel and plans to conduct mass production performance evaluation within this year

According to news from this site on August 22, ETNews quoted industry insiders as saying that LG Display has successfully developed an OLED panel that uses blue phosphorescence, thereby greatly improving OLED energy efficiency, thereby reducing power consumption, extending battery life, and improving brightness, providing a OLED has laid an important foundation for further development. Note from this site: OLED panel organic substances can be divided into "phosphorescent" and "fluorescent" according to their light-emitting methods. Phosphorescent materials can theoretically achieve nearly 100% exciton energy conversion rate, while fluorescent materials can only achieve 25%. To put it simply, OLED products currently on the market have successfully applied phosphorescence to red and green pixels in the three primary colors. However, the development of phosphorescent materials in the blue part is difficult due to life and color accuracy issues (blue wavelength is short and energy is high, resulting in Decreased stability), so fluorescent materials are still used, so blue phosphorescent OLED is also known as the "last problem of OLED" (for example, Samsung developed a diamond arrangement to solve the problem of low blue luminous efficiency, which is also currently recognized as the optimal arrangement).

▲ Source: UDCETNews reports that LG Display uses a "hybrid" method of mixing blue fluorescent materials and phosphorescent materials to combine the longevity of fluorescent materials with the high-efficiency characteristics of phosphorescent materials to achieve the same results as today's Has the same longevity as OLED.

An industry insider also mentioned, "Dual-stack tandem technologyhas played a key role, and the first blue phosphorescent display is expected to be commercialized."
