Abstract: Techniques and architectures involving fabricating a display panel, such as an electro-wetting display panel include laminating a first support plate and a second support plate together to form a laminated display panel. The laminated display panel includes an ultra-violet (UV) light curable seal disposed between the first support plate and the second support plate proximate to edges of the laminated display panel. After conveying the laminated display panel to a UV light curing station, pressurized air, gas or fluid is applied to the laminated display panel to produce a pressure on the UV light curable seal between the first support plate and the second support plate. While applying the pressurized air, gas or fluid, the laminated display panel is exposed to UV light to cure the seal.

Abstract: A display device includes a first support plate and an opposing second support plate. A wall is formed on the first support plate. A portion of the wall is associated with an electrowetting pixel. A distal end of the wall portion forms a non-planar contact surface having a first surface feature. A spacer is positioned between the second support plate and the wall portion. The spacer has a distal end forming a non-planar contact surface with a second surface feature complementary to the first surface feature. The non-planar contact surface of the spacer contacts the non-planar contact surface of the wall portion.

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.
