Modos Paper Monitor: Open-hardware E-ink with 75 Hz refresh rate
Why is e-paper still so slow E-paper has traits a regular monitor can’t match. No flicker, no glare in your eyes, the image stays after power is cut, it’s readable in direct sunlight, and viewing angles are excellent. Yet twenty years after the first readers it still hasn’t moved much beyond e-readers, shelf labels, and a handful of expensive monitors. The bottleneck is refresh speed. E-paper has come a long way in two decades – higher resolution, faster updates, more colors for the same money – but none of that has been enough for wider adoption. The fastest panels manage one refresh per second; most are slower. Writing on them feels laggy, and the cursor jumps instead of gliding. The Modos Tech team in Boston tackled both problems at once. FPGA driver board The heart of the kit is an FPGA. Instead of a fixed circuit it can be configured to behave like whatever logic you need. The advantage is speed: image processing runs in parallel hardware rather than step-by-step in code. The configuration Modos loads is called Caster and is open source. Caster drives the panel differently from conventional controllers. It splits the screen into independent regions instead of…
