With these new displays and home CNC machines, it's clear that we really are living in the future aren't we? Decades ago we'd be talking about putting 4" CRTs in the marquee. With the proliferation of small LCD devices, we move on to something like an iPod or android/iPhone screen. When RGB panels came out, that looked inviting for a while but too low res. Then the advertising LCDs came out and the first dynamic marquee project used those, but they were pricey. Now you can get a variety of sizes from aliexpress for less than $200. Just wait a few years for foldable displays and you can have the marquee, display, and CPO be one big piece
