preparation example Construction
[0061] The preparation of the composition of the present invention is to select its weight percentage according to the ratio range of these several compounds, and carry out according to a conventional method. The usual conventional preparation method is to mix and heat its components to dissolve each other until the completion of the dissolution process is observed. But it is also possible to dissolve and mix the components in a suitable organic solvent (a suitable organic solvent such as acetone, chloroform or methanol), and remove the solvent after thorough mixing to finally obtain a uniform liquid crystal composition. This method must ensure that no pollutants or unnecessary dopants are introduced into the solvent.
[0062] The liquid-crystalline media according to the invention can also further comprise additives known to the skilled person and described in the literature, making it possible to use them in any type of liquid-crystal display disclosed so far.
