我自己的,6年前画的。当时一台机器售价差不多两万,利润 85% 以上。 不过这种产品不像消费电子,6年前。价格高。现在其实也还在用,只是价格一般都在一万以内了。
每个公司的LED视频处理器 大同小异,哪个品牌的,我就不说了。 做这行的人去照图片对比很快就知道了
下面普及一下相关知识。和案例
LED 超大屏,的背后一般都需要一个这样的设备。
6年前画的,本人PCB也是自学,没有人教过,摸着石头过河。大家找找茬。不好的地方拍砖。哈哈。
下载了。不要乱发。谢谢,不然以后都不敢发这类的资料了。 还有大量这方面的案例。
整套资料,是已经测试OK 应用过很多场合的资料。。 PCB文件和原理图, 源码就不发了。
