What Hacker News says?
The shift registers are still there on the passive panels, that's the end bit...I was talking about the controller that drives the image to the panels. It sends one row at a time, to one panel...the panels are daisy chained. So, if you have 2 panels, each 32 pixels wide, it's only sending one row of 32 pixels at a time. Add in PWM for brightness, and a PWM rate for variable brightness that's fast enough to be viewed…
