Foreign media: Chinese scientists have developed a new perovskite light-emitting diode (PeLED) technology, significantly enhancing the brightness, energy efficiency, and lifespan of LEDs, which is expected to completely transform key components of existing electronic devices.
The research team comes from the University of Science and Technology of China, Fudan University, and Nanjing Tech University. The research results were recently published in the journal Nature.
Traditional PeLEDs are difficult to commercialize due to instability and short lifespans (averaging several thousand hours), but the team used a new method to prepare perovskite semiconductor materials, enabling PeLEDs to reach a brightness of 1,160,000 nits, far exceeding commercial displays (usually several thousand nits). At 100 nits (a standard for some commercial LEDs), the theoretical lifespan exceeds 185,000 hours (approximately 21 years).
This technology balances high efficiency and durability, making it suitable for low-cost ultra-bright lighting and high-definition displays, overcoming major obstacles to the commercialization of PeLEDs and demonstrating significant application potential.
