Abstract:
1. A method for sealing a microcell comprising the operations of: forming a microcell cavity including a wall substantially surrounding an opening; placing a display material inside the microcell cavity; placing a pressure sensitive adhesive tape such that the tape adheres to the wall and covers the opening; and, exposing an adhesive polymer in the adhesive tape to radiation having a wavelength between 200 and 500 nm, the radiation to crosslink polymer molecules in the adhesive such that a first region of the adhesive tape in contact with the wall bonds to the wall, the crosslinking of polymer molecules in the adhesive causing a second region of the adhesive tape placed over the opening to have a substantially reduced tack such that the display material inside the microcell cavity may contact the crosslinked polymer tape without significant degradation of a contrast ratio of the display.
