Abstract
A novel method of sealing ink in a microcell is described. A microcell is formed and an ink deposited in the microcell. A pressure sensitive tape seals the microcell. Ultraviolet light changes the properties of the adhesive in the pressure sensitive tape such that the material deposited in the microcell does not adhere to the adhesive. The described method is particularly useful for forming display structures.
