Neoluxiim demos solar-powered e ink display

We've been sort of wondering when we'd see a solar e-ink display, and here we are -- Neoluxiim is demoing this panel for use in point-of-sale advertising. What's interesting here is that the background appears to be in color while the text is black, but we're assuming that's just a fixed image behind the e-ink layer. Everyone ready for impulse purchasing to go high-tech? Video after the break.
