Abstract
An electrowetting display comprises a bottom support plate including pixel walls and a top support plate that includes spacers. The pixel walls and/or the spacers may be joined together to create a joined spacer and pixel wall before being fully cured. In some configurations, the pixel walls and the spacers are made from photoresist that is not fully cured before assembly of the display. After aligning the spacers over the pixel walls, the spacers and pixel walls are joined. In some configurations, the junction of the pixel walls and the spacers is exposed to UV light to more fully cure the photoresist. In addition, or alternatively to exposure to the UV light compressive force may be applied to fuse the pixel walls and spacers. The assembled display may also be exposed to a final bake to more fully cure the photoresist.
