Steve Smith answers the question on how colored e-ink works.
Episode #8-49 released on July 29, 2018
Today, I shall be discussing the technique in which colored e-ink works. It is relatively the same technique as black and white e-ink, which I have talked about before, which you can go see by going to tqaweekly.com/se8ep03. There are a few extra features that allow colored e-ink to work while retaining many of the properties of black and white e-ink screens.
To recap, the black and white particles in an e-ink display are charged either positively for black, or negatively for white. Only the white particles let light through, which is important for the blacklights. The amount of light blocked can allow for a kind of shading to occur, basically an attempt at making gray. This is important for colored e-ink displays to work.
A colored e-ink display adds to the black and white e-ink experience through the use of red, green, and blue light filters, which combined with the black and white particles beneath to allow the production of thousands of colors. Certainly not the millions of colors we can expect from our typical LCD monitors and screens, but definitely a lot of color for that type of screen.
