I'm looking at creating a pixel matrix of high density. My plan is firstly to create a matrix 2.5m long (1/2 a strip) running of a p12s. So too start with only 6 strips. 12 pixels high. Then add to it in the upcoming years making it taller. Because if this I want to get the highest pixel count from a strip I can. All my display so far is ws2811 and dc12v but I can't seem to find anything with a high pixel count. I did find this one though http://m.aliexpress.com/item/1342925458.html?tracelog=storedetail2mobilesitedetail Also what is better, strip in silicone tube or strip in silicone coating. I think a few years ago I had some white LEDs in silicone coating and I found it really hard to solder so I have up.
