一、核心组件：发光二极管 (LED)：LED 是 LED 显示屏的像素，是最基本的发光单元。①电致发光：当电流通过特殊的半导体材料时，电子和空穴复合，以光子的形式释放能量，从而发光。②颜色原理：单个 LED 芯片可以[…]

一、SMD(Surface Mounted Device)Led Display Screens: 1) SMD Led Displays working principle and appearance: ①Packaging structure: The red, green, and blue chips are packaged together in the same bracket to form a tiny, square dot, which is a complete full color pixel unit. ②Installation method: Surface mount technology is used, pads are prefabricated on the PCB

一、同步控制与异步控制的区别：①同步控制：屏幕内容与电脑显示器实时同步。电脑上显示什么内容，LED屏幕都会立即显示相同的内容，相当于电脑的扩展显示器。②异步控制：屏幕可以独立运行。
