  • Patent number: 7534545
    Abstract: A laser induced thermal imaging (LITI) apparatus and a method of making an electronic device using the same are disclosed. The LITI apparatus includes a chamber, a substrate support, a contact frame, and a laser source or oscillator. The LITI apparatus transfers a transferable layer from a film donor device onto a surface of an intermediate electronic device. The LITI apparatus uses a magnetic force to provide a close contact between the transferable layer and the surface of the intermediate device. The magnetic force is generated by magnetic materials formed in two components of the LITI apparatus that are spaced apart interposing transferable layer and the surface of the intermediate device. Magnets or magnetic materials are formed in the two following components of the LITI apparatus: 1) the intermediate device and the film donor device; 2) the intermediate device and the contact frame; 3) the substrate support and the film donor device; or 4) the substrate support and the contact frame.

  • Patent number: 7534543
    Abstract: A thermal transfer donor element is provided which includes a support, light-to-heat conversion layer, interlayer, and thermal transfer layer. When the donor element is brought into contact with a receptor and imagewise irradiated, a portion of the transfer layer is transferred to the receptor. The relative surface texture of the layers can be at least partially controlled, prior to imaging of the donor element, for desired effects in the resulting receptor device. The construction and process of the donor element is useful in making colored images including applications such as color proofs, color filter elements, and organic light emitting displays.

  • Patent number: 7534544
    Abstract: In a method of using a donor element in a radiation-induced thermal transfer process, an assemblage is provided that includes a donor element and a receiver element, wherein the donor element has a support layer and a transfer layer having one side adjacent the support layer and the other side adjacent the receiver element. After image-wise exposing the assemblage to radiation whereby a portion of the transfer layer is transferred to the receiver element, relative movement between the support layer and the receiver element is provided before separating the donor element from the receiver element. Advantages include improved edge straightness, image width predictability, improved thermal mass transfer, and improved color filters.

  • Patent number: 7504190
    Abstract: The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color.
