The future of LED depends on these technologies
2022-09-27
When a new technology begins to appear, it often brings many hopes and possibilities. Recently, what new technologies are there in LED industry? Will future industrial development depend on these technologies?
White LED is widely used in plane lighting and other fields, and the phosphors used as color conversion materials usually contain some rare earth elements (REEs). This is an unsustainable plan, after all, in the long run, the exploitation and use of rare earth elements will have a very negative impact on the economy and the environment.
Therefore, developing color conversion materials with high flexibility, stability and light efficiency without rare earth elements has always been a research topic in this field. In recent years, flexible lamps and flexible displays made of ultra-thin OLED panels have appeared in the market, but up to now, these products still have problems such as poor reliability and high driving current. To solve these problems, researchers have done relevant research and significantly improved the light efficiency, reliability and color adjustability of quantum dots.
