Abstract
Provided is a flexible cell unit and a method of manufacturing the same. The cell unit includes first and second substrates separated by a controlled distance maintained by spacers, filled with an electro-optic material and enclosed by a border seal. The method includes providing two sheets to form the first and second substrates, where at least one of the sheets is flexible, depositing an electro-optic material on at least one substrate, and roll-filling the cell by using one or more lamination rollers to pair the first and second substrates to within the controlled distance of each other and filling the controlled distance with the electro-optic material.
