XLED点阵显示模块

1、8*8LED点阵显示模块中国海洋大学工程学院中国海洋大学工程学院刘滨点阵显示模块LED发光二极管（Light Emitting Diode） 发光二极管简称为LED。由镓与砷、磷、氮、铟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。LED发光管单向导电电路符号电路符号单色8*8LED点阵显示模块双色8*8LED显示模块1088BRG点阵模块引脚图LED点阵显示原理1 1、行给高电平，列给低、行给高电平，列给低电平，对应的电平，
