However, expanding this to two-dimensional systems presented new challenges, including the risk of disruptions in the liquid-crystal patterns that would affect light behavior. To overcome this ...

Here, we pitch the E Ink ACeP Gallery Palette against cholesteric liquid crystal (ChLCD) from IRIS Optronics to find out which trumps the other in its ability to render color images in all their ...
