OLED，即有机发光二极管（Organic Light-Emitting Diode），由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。其根据驱动方式的不同分为主动式OLED（AMOLED）和被动式OLED（PMOLED）。近年来，OLED因其优势在各领域有了突破性发展，并广泛应用于MP3显示，在照明领域也有可观的前景。许多公司也于展览会、期刊等展示了OLED的各种先进产品。本文将讨论各种OLED技术和适当的偏压电源供应电路，而关于OLED技术和驱动方法的选择，也会影响电源供应电路的需求。并应用单片机驱动OLED显示相应文字图案。

Lithium–sulfur batteries are a promising energy-storage technology due to their relatively low cost and high theoretical energy density. However, one of their major technical problems is the shuttling of soluble polysulfides between electrodes, resulting in rapid capacity fading. Here, we present a metal–Organic framework (MOF)-based battery separator to mitigate the shuttling problem. We show that the MOF-based separator acts as an ionic sieve in lithium–sulfur batteries, which selectively sieves Li+ ions while e ciently suppressing undesired polysulfides migrating to the anode side. When a sulfur-containing mesoporous carbon material (approximately 70 wt% sulfur content) is used as a cathode composite without elaborate synthesis or surface modification, a lithium–sulfur battery with a MOF-based separator exhibits a low capacity decay rate (0.019% per cycle over 1,500 cycles). Moreover, there is almost no capacity fading after the initial 100 cycles. Our approach demonstrates the potential for MOF-based materials as separators for energy-storage applications.
