LED ,发光二极管(light emitting diode缩写)。它是一种通过控制半导体发光二极管的显示方式,由镓(Ga)与砷(As)、磷(P)、氮(N)、铟(In)的化合物制成的二极管,当电子与空穴复合时能辐射出可见光,因而可以用来制成发光二极管。在电路及仪器中作为指示灯,或者组成文字或数字显示。磷砷化镓二极管发红光,磷化镓二极管发绿光,碳化硅二极管发黄光,铟镓氮二极管发蓝光。
MeiShan LED display, LED display : a flat panel display, consisting of small panel LED module.
LED, light-emitting diode. It is a semiconductor light emitting diode control through the display mode, by gallium (Ga) and arsenic (As), phosphorus (P) and nitrogen (N), indium (In) compounds made of diode, when electrons and holes composite can radiate light, thus it can be used to make leds. As an indicator light in a circuit or instrument, or as a text or a digital display. Phosphorous arsenide diode emits red light, phosphating gallium diode emits green light, silicon carbide diodes emit yellow light, and indium gallium nitrogen diodes emit blue light.
LED displays are generally used to display text, images, video, video signals and other information.
