Low birefringence encapsulated liquid crystal and optical shutter using same. |
摘要 |
<p>A liquid crystal material composition has a low, preferably zero or near zero, birefringence characteristic. Such material is mixed with a quantity of pleochroic dye to form a solution therewith to increase absorption characteristics and is encapsulated; and such encapsulated material may be used as an optical light control device or optical shutter in which light intensity may be controlled without distorting or at least without substantially distorting the optical image transmitted therethrough. </p> |
