摘要:
An ink sheet (3) is wound around rollers (6), and a recording sheet (4) is placed with a space (d) between the ink sheet (3) and the recording sheet (4) and is advanced. The thickness of the space (d) is a value in the range of 1 to 100 .mu.m. The ink sheet (3) is irradiated with a laser beam (L) emitted by a laser (5) to transfer the dye contained in a dye layer formed on the ink sheet (3) from the ink sheet (3) to the recording sheet (4) for printing. The dye layer of the ink sheet (3) is replenished with the dye (30, 30A) heated and fused by a heater (9) by a dye supply unit (7) at a position other than a position where the ink sheet (3) is irradiated with the laser beam (L). Since the ink sheet and the recording sheet are held with the space (d) having a thickness in the range of 1 to 100 .mu.m, the dye once transferred to the recording sheet is not transferred from the recording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed. Since the dye layer of the ink sheet is replenished with the dye, the ink sheet can be repeatedly used, so that no waste is produced.
摘要:
A wavelength multiplexed optical recording material is disclosed wherein a photosensitive material including substituted porphine, such as tetra(pentafluorophenyl) porphine or tetra(4-methoxyphenyl) porphine, is uniformly dispersed into an optically transparent dispersion medium. When such wavelength multiplexed optical recording material is cooled to a temperature of liquid helium and irradiated with a laser beam, a large number of holes of narrow width are formed in an inhomogenous absorption band under the phenomenon of photochemical hole burning. As compared to unsubstituted porphine, the above porphine derivatives give an improved recording sensitivity and narrow hole width.

Disclosed herein is a light emitting device, which includes a light emitting element configured to emit a light, and a concave mirror portion configured to reflect the light emitted from the light emitting element, the concave mirror portion being erected on a circumference of an emission surface of the light emitting element. The concave mirror portion has a light reflecting surface obtained by rotating a part of a parabola. A central axis of the rotation is set in a position of passing through a side of the parabola with respect to a middle point of a line segment joining the part of the parabola and a focal point of the parabola.

The invention provides a display unit which can improve emission efficiency of lights for image display, and assure luminance of display images. The display unit comprises micro prisms which are arranged in the positions corresponding to organic EL devices, and which have a high refraction index to refract a light, and auxiliary prisms with a low refraction index which are embedded in voids between each micro prism. A light volume of the light viewed as an image in the direction facing an organic EL display (facing direction) is a total of a light volume of a light essentially emitted from the organic EL device in the facing direction, and lights which are directed in the facing direction by utilizing refraction phenomenon based on differences of refraction index between the micro prism and the auxiliary prism. Compared to the case wherein the micro prisms and the auxiliary prisms are not provided, an emission volume of the light in the facing direction is increased by the light volumes of the lights.
摘要:
An optical recording medium has a transparent substrate with a recorded pattern formed thereon and a saturable absorption dye containing layer disposed on the recorded pattern and containing at least a saturable absorption dye. The saturable absorption dye has a molecular extinction coefficient .epsilon. of 10.sup.4 or greater at the wavelength of reproducing light, and a relaxation time .tau. in the range of 1 ns.ltoreq..tau..ltoreq. 100 ns. A reflecting layer having a reflectivity of 70% or higher on an air boundary thereof may be disposed on the saturable absorption dye containing layer. The saturable absorption dye containing layer may have such a thickness that substantially minimizes the intensity of reflected light due to interference with respect to the intensity of the reproducing light. The saturable absorption dye may comprise a naphthalocyanine-based dye.

摘要:
An organic electroluminescent display device includes scanning lines, signal lines, and pixels formed in a matrix, each pixel being at an intersection of each of the scanning lines and each of the signal lines. Each pixel includes a light-emitting element, a light-emitting circuit composed of a thin-film transistor, and a light-receiving circuit composed of a thin-film transistor. When the light-emitting circuit is selected by the scanning line, the light-emitting circuit drives the light-emitting element according to a video signal that is input from the signal line, thereby displaying an image on the pixels formed in the matrix. The light-receiving circuit is selected in a period of time during which the light-emitting circuit does not operate, and outputs a light-receiving signal in accordance with the amount of light incident on the pixel to a different signal line.
