A few years back there was a promising Dutch startup called Liquavista working on “electro wetting” - a kind of next-gen full-color low-latency reflective display tech that functioned a lot like LCD, but instead of modulating LC orientation, they would quickly tune the hydrophilicity of pixel-size glass cells that would cause an ink droplet to either bead up in the corner (become transparent) or wet the entire pixel. Sounded really cool. They got bought by Amazon and haven’t heard anything since. https://lookgadgets.com/liquavista/ https://lookgadgets.com/liquavista/
