  • Patent number: 7537878
    Abstract: A method of fabricating an OLED is provided. The method includes providing a substrate, in which a pixel electrode is formed. In addition, the method includes laminating a donor substrate attached to a frame on an entire surface of the substrate, and irradiating a laser to a predetermined region of the donor substrate to form an organic layer pattern on the pixel electrode. The present invention provides a method of fabricating the OLED capable of suppressing generation of contaminants such as particles and so on, and preventing the donor substrate from sagging or bending, as well as improving transfer efficiency since the donor substrate and the substrate are readily adhered to each other to maintain vacuum state.

  • Publication number: 20010005572
    Abstract: The present invention is an imaging element which includes a support, an imaging layer superposed on a side of said support and an overcoat overlying the imaging layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the imaging layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. The present invention is a photographic which includes a support, a silver halide emulsion layer superposed on a side of said support and an overcoat overlying the silver halide layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the silver halide emulsion layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. In one embodiment, the discontinuous overcoat is a series of parallel stripes.

  • Patent number: 6221554
    Abstract: There is described a self-developing film unit which has a photosensitive member and an image-receiving member and wherein one outermost surface of the film unit comprises a support layer carrying a layer of a releasable material and a layer of an adhesive material. After an image is formed in the film unit by photoexposure of the photosensitive element and photographic processing of the exposed photosensitive element, the support and releasable material layer can be removed and the film unit or the image-receiving element, as the case may be, adhered to a surface for viewing of the image.
