 Inorganic light emitting diode, LED, displays are becoming increasingly popular due to their high efficiency and long lifespan. These displays are made up of LED chips which are typically smaller than 200 microns, allowing them to achieve higher resolution while maintaining efficiency. Additionally, these chips are also able to provide local dimming, improving contrast ratios at lower energy consumption. Micro-LEDS, with chip sizes under 100 microns, are still being developed and researched, but they hold great potential for future applications such as full-color solutions, color conversion, and optical lenses. This review provides an overview of current technologies and a glimpse into the future of inorganic LED displays. This article was authored by Tingzhu Wu, Qin Weishu, Yulin, and others.
