LED电子屏由、驱动电路板、或模组、控制系统(单片机)、编缉软件、外框、如果你想做这种行业赢利的话直接到专门的批量生产LED电子屏的厂家买成品电路驱动板、再买个电子屏控制系统就可以了。拿来调试一下就可，自己生产小屏费时费力不划算。希望能帮到你。

你好，LED条屏构造势由单元板，电源，控制卡，连线组成的哦，单元板是LED的显示核心部件之一，单元板的好坏，直接影响到显示效果的。单元板由LED模块，驱动芯片和PCB电路板组成。LED模块，其实是由很多个LED发光点用树脂或者塑料封装起来点阵。希望可以帮到你哦。

1.单元板接到适配电源上的一定要是GND连 COM。VCC连接+V。假如你是20块板子大的屏，那就是两个适配电源，每10块板子连接一个适配电源。以此类推。
2.接完了电源线和排线以后就剩下控制卡的连接了。控制卡的连接和单元板连接是一样的，控制卡背面有正负级标示，正极连接适配电源+V上面，负极连接到适配电源COM上。
3.在适配电源上有L和N的标识，这是来连接220V电压的。
