Comment on E Ink's color ePaper tech gets supersized for outdoor displays

  One of their older color products is a traditional B/W screen with an RGB filter over the top. The problem with this is the filter tends to make everything way darker and muted than it should be.

  They are also working on newer ACeP screens that use multiple colored dye and pigment particles in the same capsule. By swapping the colors around with specific electric waveforms, they can control what the color looks like from the front. The downside is that this color swapping often takes several seconds to produce the correct color ((also the color gamut has a lot of holes))
