Abstract:
A display device, a method, and a computer-readable medium. The display device includes a layer including a first region and a second region, wherein the first region and the second region are configured to be visible to a user of the display device; and circuitry configured: to control displaying a computer generated image on an optical device overlapping the layer and to control a first transmittance of the first region of the layer to be lower than a second transmittance of the second region of the layer such that: a visibility, through the first region, of the computer generated image is increased and a visibility, through the second region, of an environment opposite the user relative to the display device is higher than a visibility, through the first region, of the environment opposite the user relative to the display device.
Abstract:
A security device that elicits at least one dynamic response upon acceleration, or upon change of orientation with respect to gravity, wherein the dynamic response continues after cessation of the acceleration or the change of orientation. In addition, the dynamic response can be optical, such that it is visually observable by an unaided human eye. Alternatively, the response can be machine readable. In some cases, the dynamic response has duration of from about 0.01 s to about 100 s, or from about Is to about 10s.
Abstract:
A passive electronic paper based on a monochromatic electrophoretic particle. The invention based on the formation of pigment (particles) that are a half black and a half White, wherein no interconnection and processing circuitry is needed to address each particle. The polarization (addressing) of the particles depends on the magnetic induction, the orientation (polarization) of the particles generate the paper foreground (black color) for activated particles and background (white color) for inactivated particles. A magnetic flux oriented for a single polarity embedded as pen tip, the magnetic pen tip used to polarize the particles. Paper contrast (foreground) will change according to the pen movement over the paper surface. A bar comprising of magnetic flux of anti-polarity of the pen tip can be used for depolarization. Depolarization rests all particles to background state (white paper). Based on this invention arrangement, smart passive e-paper and pen can be developed so as to utilize traditional writing.
Abstract:
The present invention is directed to a display panel comprising micro-containers filled with an electrophoretic fluid wherein each of the microcells has a bottom and one surface of the bottom is in contact with the electrophoretic fluid, the display panel has a first area and a second area, and the microcells in the first area have substantially the same bottom thickness and the microcells in the second area have added bottom thicknesses. Such a display panel is useful for many applications, such as bar codes, anti-counterfeiting labels, direction signages, shelf labels or watermarks.
Abstract:
An electro-optic display (100) has a viewing surface through which a user views the display (100), a bistable, non-electrochromic electro-optic medium (108), and at least one electrode (104, 112) arranged to apply an electric field to the electro-optic medium (108). The display comprises at least 10 micromoles per square meter of the viewing surface of at least one redox compound having an oxidation potential more negative that about 150 mV with respect to a standard hydrogen electrode, as measured at pH 8.
Abstract:
An optical see-through head-mounted display device includes see-through lens which combines an augmented reality image with light from a real-world scene, while opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of LCD panel can be selectively controlled to be transmissive or opaque, based on size, shape and position of the augmented reality image. Eye tracking can be used to adjust position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.
Abstract:
An electro-optic display, intended for writing with a stylus or similar instrument, is produced by forming a layer of an electro-optic material on an electrode; depositing a substantially solvent-free polymerizable liquid material over the electro-optic material; and polymerizing the polymerizable liquid material.
Abstract:
An object is to provide an anti-reflection film which has an anti-reflection fucntion capable of further reducing reflection of incident light from external, and has excellent visibility, and a display device having the anti-reflection film. A plurality of adjacent hexagonal pyramidal projections is geometrically provided, so that reflection of light is prevented. A refractive index is changed from a display screen surface side to the outside (the air side) because of a physical form that is a hexagonal pyramid. The plurality of hexagonal pyramidal projections can be provided without gaps therebetween and each of six side surfaces thereof is provided at an different angle from a base; thus, light can be suffiently scattered in many directions.
Abstract:
An active element that is based on an electret emulsion and that comprises particles of pre-polarized electret material as emulsion in neutral liquid and both poles of the particles are coloured with different colours. For producing a neutral carrier liquid for the active element liquid fluorine carbon is used. For producing electret material for the active element solid polymerised fluorine carbon or electret wax is used. The active element is used for producing visual matrix displays, indicators, surfaces and surface coatings that change colour by the application of a control voltage.
