Liquid crystal mixtures are highly complex mixtures of several mesogenic and non-mesogneic molecules as well as chiral dopants, monomers, dyes, and other active dopants. There can be as many as 20 sub-components in any one LC mixture! Each subcomponent has to be specifically matched with other dopants in both chemical structure and concentration to provide the expected optical, thermal and electrical performance needed. Slight deviation or impurity can adversely affect the stability of the mixture and result in undesirable phase separation. Expertise in formulating liquid crystal mixtures comes only after years of experience and testing and is the prime reason why the suppliers of liquid crystalline material are limited.
AlphaMicron has spent over 20 years studying liquid crystal materials and formulations. It has created a library of materials that can be used in various mixtures and catalogued their effects in guest-host systems. To meet the particular requirements needed for a final system, chemists and physicists at AlphaMicron formulate specific mixtures that will precisely meet each requirement to arrive at a final product.
