  • Patent number: 10586392
    Abstract: Information representing a position and orientation of a captured image or information for deriving the position and orientation is acquired from the captured image as extraction information, and a reduced-information-amount image is generated by reducing an amount of information in the captured image in accordance with a distance from a position that a user is gazing at in the captured image. The reduced-information-amount image and the extraction information are outputted to an external device, and a composite image that has been generated based on the reduced-information-amount image and an image of a virtual space generated by the external device based on the extraction information is received.

  • Patent number: 9136309
    Abstract: An organic electroluminescent (EL) display includes a plurality of organic EL devices for red, green, and blue subpixels, each including a first electrode on a light output side, a second electrode opposite the first electrode, and an organic compound layer including a light-emitting layer therebetween. The organic EL devices have a resonator structure between a first reflective surface closer to the first electrode than the organic compound layer and a second reflective surface closer to the second electrode than the organic compound layer. A predetermined white color is displayed by mixing the three colors such that an optical distance of the organic EL devices of each color between an emission position in the light-emitting layer and the second reflective surface is set within ±10% from an optical distance corresponding to an nth-order minimum of a curve of required current density against at least the optical distance.

  • Patent number: 8999738
    Abstract: A method for manufacturing an organic electroluminescent display apparatus including a plurality of organic electroluminescent devices at least containing a fused ring compound having an anthracene skeleton, includes, in the following order: forming an organic electroluminescent layer on a substrate on which a first electrode has been formed; processing the organic electroluminescent layer; forming a second electrode on the organic electroluminescent layer; and providing a sealing member covering the organic electroluminescent layer, in which the organic electroluminescent layer is not exposed to an environment containing oxygen and including light of a wavelength shorter than a wavelength of a long wavelength edge of an absorption spectrum of the fused ring compound having an anthracene skeleton from forming the organic electroluminescent layer until completion of providing the sealing member.

  • Publication number: 20120025732
    Abstract: A light emitting device contains organic EL elements of different colors and outputs light emitted from the organic EL elements, in which, when outputting white light, the organic EL element, in which the luminance when light is emitted at a current density at which a luminous efficiency reaches a maximum is lower than that of the organic EL elements of the other colors, among the organic EL elements of different colors emits light with a current having a current density higher than the current density at which the luminous efficiency reaches the maximum and a highest duty among the organic EL elements of different colors, and the organic EL elements of the remaining colors emit light with a current having the current density at which the luminous efficiency reaches the maximum and at a duty lower than the duty.

  • Patent number: 7733325
    Abstract: An electrophoretic display apparatus is equipped with first and second substrates, an electrophoresis dispersing liquid, and first and second electrodes, and has a display state made to be a planar distribution state of charged migration particles. A first planar distribution state with the charged migration particles spread on the first or second substrate from the first electrode toward the second electrode, and a second planar distribution state with the charged migration particles spread on the first or second substrate from the second electrode toward the first electrode are formed alternately.

  • Patent number: 7259745
    Abstract: A method for driving a display apparatus having display memory property is provided. In the method, the display apparatus includes an electrode group composed of at least a first electrode and a second electrode. The method includes the steps of: applying a voltage for performing writing of an display image between the first electrode and the second electrode; and attenuating an absolute value of a potential difference between the first electrode and the second electrode in a term within a holding period of the display image. Thereby, the deterioration of a holding characteristic owing to the influence of a residual DC can be prevented.
