    Abstract: An organic electroluminescence display device made by a laser induced thermal imaging process has a substrate having first and second electrode layers, and an organic layer having red, green, and blue light-emitting layers between the electrode layers. Thermosetting light-emitting materials are used to form the red, green, and blue light-emitting layers, and a laser is then selectively irradiated onto a light-to-heat conversion layer formed on the substrate to deliver heat energy converted from light energy through the light-to-heat conversion layer to the thermosetting light-emitting materials so that curing is progressed to form patterned light-emitting layers. In accordance with the fabrication method of the present invention, the light-emitting materials may be patterned using a laser, thereby fabricating a large scaled organic electroluminescence display device and simplifying the process by not using a mask when the light-emitting layers are formed.

  • Patent number: 7396631
    Abstract: Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.

  • Patent number: 7226890
    Abstract: A thermal printing ribbon that has reduced or no wrinkling during printing includes inorganic particles in a polymeric host material in at least one layer of the ribbon. The ribbon has improved mechanical and thermal properties as compared to ribbons not incorporating the inorganic particles. The ribbon can be used to form images on a dye-receiver element wherein the images have few or no artifacts caused by wrinkling of the thermal printing ribbon. The ribbon can be used in high speed printing.

  • Patent number: 6894002
    Abstract: A receiver medium for digital imaging comprises a substrate having a dye-receiving surface bearing a coating comprising a highly branched functionalised polymer of generally globular form, e.g. a dendrimer, dispersed in a host polymer. Functional groups at or near the surface of the branched polymer, may interact with and bind dye molecules having complementary functional groups, eg dyes as disclosed in WO 96/34766, e.g. by acid-base interaction, thus having the effect of chemically fixing the dye within the coating on the receiver medium. Because dye molecules can be chemically bound to the branched polymer in the receiver sheet, it is possible to use host polymer materials of lower Tg than generally required in the prior art, with the host polymer typically having a Tg of less that 50° C. This means that dye molecules can have significantly increased diffusivity through the coating, prior to interaction, resulting in a more even distribution of dye through the coating than has been possible hitherto.
