The molecular arrangement modifications when an external bias takes place, building one particular spot show up darkish and another region appear distinct.
So that you can Allow mild by way of, the crystals rotate parallel, or “in-aircraft,�?when voltage is applied. The picture top quality of those screens is drastically Improved by this behaviour in several approaches.
