LCD (Liquid Crystal Display) re-writing pads typically use a type of liquid crystal material. The liquid crystals in these devices are usually composed of organic molecules that can flow like a liquid but have some of the ordered properties of a solid crystal.
The specific type of liquid crystal used in these re-writing pads is often a mixture of various nematic liquid crystals. Nematic liquid crystals are a type of liquid crystal in which the molecules are oriented in roughly the same direction but do not have positional order. This property allows them to change their orientation when an electric field is applied, which is how the writing and erasing function works in LCD re-writing pads.
Additionally, these pads may also use a cholesteric liquid crystal, which can maintain a stable written state without continuous power. This property makes cholesteric liquid crystals particularly suitable for low-power or passive display applications like LCD re-writing pads.
