Recent advances in micro-pixel light emitting diode technology

초록

Display technology has developed rapidly in recent years with III-V system-based micro-light-emitting diodes (μLEDs) attracting attention as a means to overcome the physical limitations of current display systems related to their lifetime brightness contrast ratio response time and pixel size. However for μLED displays to be successfully commercialized their technical shortcomings need to be addressed. This review comprehensively discusses important issues associated with μLEDs including the use of the ABC model for interpreting their behavior size-dependent degradation mechanisms methods for improving their efficiency novel epitaxial structures the development of red μLEDs advanced transfer techniques for production and the detection and repair of defects. Finally industrial efforts to commercialize μLED displays are summarized. This review thus provides important insights into the potential realization of next-generation display systems based on μLEDs. © 2024 Author(s).
