这些 LED 显示屏通常采用多点配置（每个串行接口多个显示屏，RS485）以串行方式连接。据我所知，这种协议接口尚未标准化，显示器供应商将提供编程手册，解释发送到特定显示器的命令和数据。
因此，您基本上将字符串发送到串行端口，这应该不难做到。
在决定要使用的显示器之前，向供应商索要一份程序员手册和测试设备可能是个好主意。某些显示协议比其他协议更容易实现（纯 RS485 半双工协议比 PC 中没有外部协议转换器或专用 RS485 扩展卡的全双工协议更难实现）和/或它们支持的显示器范围（1 行） ，矩阵，...）和特殊功能（例如可编程字符集以创建半图形特殊显示）等。
From a price point of view LED displays are hard to beat, and if you select a decent vendor their reliability and lifespan are close to eternal.
Quite often these LED displays are connected serially, in a multidrop configuration (multiple displays per serial interface, RS485). As to my knowledge that kind of protocol-interface isn't standarddized, the display vendor will provide a programming manual that explains the commands and data to send to the specific display.
So, you'll basically be sending strings to a serial port, and that shouldn't be too hard to do.
It might be a good idea to ask the vendor for a copy of the programmer's manual and also a test device before deciding on the display you're going to use. Some display protocols are easier to implement than others (pure RS485 halfduplex protocols are much harder to implement than fullduplex protocols without an external protocol converter or specialized RS485 expansion card in the PC), and/or the range of displays they support (1-line, matrix, ....) and special features (e.g. programmable character sets to create semigraphic special displays), etc.

从价格的角度来看，LED 显示屏很难被击败，如果您选择一个好的供应商，它们的可靠性和使用寿命几乎是永恒的。
