  • Patent number: 9276238
    Abstract: An organic light-emitting diode manufactured from an organic light-emitting diode substrate in which a concave-convex structure is provided in at least a part of the surface, in which the concave-convex structure is capable of obtaining an atomic force microscope (AFM) image in which a plurality of dots is dispersed when observed by an AFM. A histogram is created by measuring a diameter (nm) of each of the plurality of dots present in a randomly selected region having an area of 25 ?m2 on the atomic force microscope image, resulting in a plurality of peaks including one main peak and one or more sub-peaks, and the chromaticity of light emitted from the organic light-emitting diode is in a range of (x, y)=(0.28 to 0.50, 0.29 to 0.45) in a CIE standard colorimetric system.

  • Patent number: 4504837
    Abstract: A recording method comprises the steps of selectively applying heat to individual heat sensitive color forming sheets each comprising a supporting sheet and a transparent color forming layer on the supporting sheet, which color forming layer is adhesive and develops a color under the action of heat but the colors developed in the individual layers being different from each other, thereby forming monochromic images in different colors on the individual color forming sheets; and separating each color forming layer with the formed monochromic image from the corrresponding supporting sheet and laying the separated individual layers on a common base sheet successively in layers making use of their own adhesiveness.
