Comparative Analysis of Electronic Display Technologies and Their Application Scenarios

Recent advances in display technology have led to Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED), Mini Light-Emitting Diode (Mini-LED), and Micro Light-Emitting Diode (Micro-LED) as the competing and complementing solutions.Their light-emission processes, physical principles, and performance parameters, e.g.brightness, contrast, power consumption and life time, vary significantly among the involved technologies.We discuss their working principles: LCD modulates liquid crystal (LC) with Mini-LED backlight to achieve better local dimming, OLED uses self-emissive organic layers with high contrast and flexibility, and Micro-LED adopts microscopic inorganic emitters with high brightness and long lifetime.The study provides an analysis of the best option by considering technical features and practical benefits and pitfalls of each of these methods.Mini-LED makes the existence of LCD tolerant by cost-effective refinement, OLED is a leader in portables and flexibles, and Micro-LED offers ample promise for next generations of use, including AR and VR.The evaluation indicates that there is no one-size-fits-all technology, and these technologies will coexist in the upcoming display world.This work helps clarifying the technology choices in design and highlights the needs for ever constant innovations to meet a wide range of applications.
