Abstract
A method for filling a liquid crystal (LC) cell with liquid crystal comprises the step of placing the LC cell having a LC cavity therein and LC inlet openings in its top and bottom edges, in a vacuum chamber which encloses upper and lower LC supply members each having a LC-impregnated yarn exposed through a slot therein. The method includes the steps of evacuating the vacuum chamber, moving the LC supply members to bring the yarns into contact with the top and bottom inlet openings of the cell, and returning the chamber to an atmospheric pressure to thereby cause liquid crystal to be sucked into the LC cavity through the inlet openings. Apparatus for filling a LC cell with liquid crystal is also provided.
