Abstract
Provided is a method of producing a flexible cell unit enclosed by a border seal and filled with an electro-optic material. The flexible cell includes a first and a second substrate separated by a controlled distance maintained by spacers. The method includes providing two continuous sheets of flexible plastic material to form the first and second substrates and depositing an electro-optic material on at least one substrate. The electro-optic material is non-encapsulated, non-polymeric, and contains less than 1% polymerizable material. The method also includes pairing the first and second substrates while roll-filling the flexible cell with the electro-optic material using one or more lamination rollers so that the electro-optic material completely fills the controlled distance between the first and second substrates.
