Abstract
A method for fabricating electronic displays comprises placing a fluoropolymer layer on a support plate for the electronic display device and etching the fluoropolymer layer. Etching changes a surface of the fluoropolymer layer so that the fluoropolymer layer becomes less hydrophobic. Pixel walls are formed on the hydrophilic surface of the fluoropolymer layer to form an array of electrowetting display elements. The fluoropolymer layer is subsequently immersed in a vapor or a liquid that is heated to heat the surface of the fluoropolymer layer. Such immersion allows the surface of the fluoropolymer layer to reflow and to become more hydrophobic.
