A cholesteric liquid crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals.
Roll to roll manufacturing of flexible materials is a well know art. High volume manufacturing of liquid crystal displays and functional liquid crystal panels is a well know art.
The eWriter works on the principle of anisotropic flow, a unique feature of cholesteric liquid crystals, in which crystals flow at different rates, depending on the direction of pressure being applied.
