ABSTRACT:
Various improvements are provided in gas-based electrophoretic displays, including (a) the use of water getters to remove water from the gas; (b) the use of electron accepting or donating gases; (c) the use of electrophoretic polymer particles having high glass transition temperatures; (d) lateral movement of electrophoretic particles within the display; and (e) the use of variable thickness coatings on electrodes to provide for gray scale.
