  • Patent number: 6731361
    Abstract: Display panels and methods for fabrication are disclosed for an in-plane switching mode display to reduce or eliminate image sticking. The display panel includes a substrate with a first electrode formed on the substrate. A dielectric layer is formed on the substrate, and the dielectric layer forms an opening down to the first electrode so that the dielectric layer is eliminated over the first electrode. A second electrode is formed on the dielectric layer, and an alignment layer is formed on the first electrode, the second electrode and the dielectric layer.

  • Patent number: 6713786
    Abstract: A pixel cell has a thin film transistor structure formed on a substrate. A signal conductor is patterned on the thin film transistor structure, and a first patterned layer of a transparent conductive material covers the signal conductor. The first patterned layer provides a pattern employed in etching a channel region of the thin film transistor structure. A dielectric layer is formed over the pixel cell and includes a via hole down to the first patterned layer of the transparent conductive material. A second layer of transparent conductive material extends through the via hole to contact the first patterned layer wherein the second layer is self-aligned to the transistor structure.
