LED数码管简介部分中英文对照
中文部分：
LED数码管分共阳极与共阴极两种，其工作特点是，当笔段电极接低电平，公共阳极接高电平时，相应笔段可以发光。共阴极LED依赖的反义词数码管则与之相反，它是将发光二极管的阴极(负极)科学养羊护国寺小吃短接后作为公共阴极。当驱动信号为高电平、Ө端接低电平时，才能发光。
LED的输出光谱决定其发光颜色以及光辐射纯度，也反映出半导体材料的特性。常见管芯材料有磷化镓(GaP)、砷化镓(GaAs)、磷砷化镓(GaAsP)、氮化镓(GaN)等，其中氮化镓可发蓝光。发光颜色不仅与管芯材料有关，还与所掺杂质有关，因此用同一种管芯材料可以制成发出红、橙、黄、绿等不同颜色的数码管。其它颜色LED数码管的光谱曲线形状与之相似，仅入，值不同。LED反转小故事数码管的产品中，以发红光、绿光的居多、这两种颜色也比较醒目。
LED数码管等效于多只具有发光性能的PN结。当PN巧开头的成语结导通时，依靠少数载流子的注人及随后的复合而辐射发光，其伏安特性与普通二极管相似。在正向导通之前，正向电流近似于零，笔段不发光。当电压超过开启电压时，电流就急剧上升，笔段发光。牛排骨怎么炖才好吃

LED digital control of the sub were both anode and common cathode, and the characteristics of their work is that when the T electrode of low-level access. Public access anode margin, the corresponding sum of luminescence can. Total digital LED cathode tube contrast, it is the LED cathode (negative electrode) short after as a public access cathode. When the driver signals to rial, Ө termination low-level, can be luminous.
LED output spectrum to determine its luminous color and light radiation purity, and it also reflects the characteristics of miconductor materials. Common Core material gallium phosphide (GaP), gallium arnide (GaAs), P GaAs (GaAsP). Gallium Nitride (GaN), which can be made GaN blue. Luminous color not only with the management of the core material, but also with the quality of doping. So to u a chip made of materials can be nt red, orange, yellow, and green color LED. Other colors of the LED digital spectral curve shape is similar, only income, the difference. LED digital control products, in red, gr
een, most, the two colors are more eye-catching. LED digital control equivalent to more than luminescent properties with the PN junction. When the PN junction conduction, on the minority-carrier injection and subquent radiation composite and luminescence, voltammetry with its ordinary diode characteristics similar. Link is the Wizard before being approximately zero current, pens of non-luminous. When the voltage exceeds the threshold voltage, current on the rapid ri of T luminescence.环境应急演练方案
