  • Patent number: 8362488
    Abstract: The present invention is directed to a flexible backplane for direct drive display devices and methods for its manufacture. The flexible backplane has many advantages. Because there is no need for a polyimide layer and only one layer of metal foil is used, the backplanes may be manufactured at a relatively low cost.

  • Patent number: 8002948
    Abstract: A process for forming a patterned thin film structure on a substrate is disclosed. A pattern is printed with a material, such as a masking coating or an ink, on the substrate, the pattern being such that, in one embodiment, the desired thin film structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structures.
