The display driving device includes: a grouper that performs grouping of a plurality of light emitting elements (for example, light emitting elements arranged on a scanning line (for example, a scanning line of the display into one or more light emitting element groups (for example, light emitting element groups based on video information input; and a driver (for example, a cathode driver that drives the one or more light emitting element groups so that driving periods do not overlap.

Display driving device and display driving method

A daylighting device according to an aspect of the invention includes at least a daylighting film that includes a base having optical transparency and daylighting portions having optical transparency and provided on one surface of the base. Each of the daylighting portions has a reflective surface by which light incident on the daylighting portion is reflected and the light reflected by the reflective surface and output from a second surface of the base has a characteristic that the light travels toward a space on a side where the light is incident on the reflective surface, the space being one of two spaces divided by a virtual plane as a boundary which is vertical to the second surface of the first substrate and parallel to a direction of the daylighting portion extending, and intervals s between adjacent daylighting portions are set to various values.

Daylighting device, molding die, and method of manufacturing daylighting film

The present invention, in one aspect thereof, is directed to a daylighting device including: a first, transparent slat configured to bend an optical path of incident outdoor light so as to emit the light in a prescribed indoor direction; a first drive mechanism configured to drive the first slat; and a control unit configured to control the first drive mechanism so as to change an angle of inclination of the first slat in accordance with a position of the sun.

Daylighting device and daylighting system

A lighting film () includes a first base material (), a plurality of lighting portions (), and a void portion (), and if a virtual straight line (F) that passes through a point (C), at which any one light ray of light entering the lighting portion () is incident on a reflective surface, and is orthogonal to a first surface () of the first base material () marks a boundary between two spaces, a space with the light ray incident on the point (C) of the two spaces is labeled as a first space (S), and a space without the light ray incident on the point (C) is labeled as a second space (S), the lighting film () has a function of decreasing intensity of light traveling toward the second space (S) of light emitted from the first base material () or the lighting portion ().

Lighting member, lighting device, and method for installing lighting member

A daylighting member includes a first daylighting section and a second daylighting section having different daylighting properties from the first daylighting section. The first daylighting section includes an optically transparent first substrate and a plurality of optically transparent daylighting portions provided on a first surface of the first substrate. The first daylighting section diffuses incoming light in a desired direction and emits the incoming light. The second daylighting section diffuses and emits the incoming light. The first daylighting section and the second daylighting section are placed side by side in a direction intersecting a direction in which the daylighting portions extend.

Daylighting member, daylighting apparatus, roll screen, and blind

A daylighting film () according to one aspect of the present invention includes a base member () having optical transparency, first projections () having optical transparency and formed on an inner surface () of the base member (), a second projection () formed on the inner surface () and having a height from the inner surface () higher than a height of the first projections (), a protective base member () arranged in an opposite relation to the inner surface () of the base member (), a bonding layer () for bonding the second projection () and the protective base member (), and gaps () defined between the first projections () and between the first projection () and the second projection (), wherein the first projections () include reflective surfaces () at which light incoming from an outer surface () side of the protective base member () or the base member () is totally reflected.

Daylighting film

A daylighting device of the present invention is provided with a planar optical memberand a support member. The planar optical memberis provided with a planar structure body which has a plurality of linear bodiesformed of optically transparent materials which are arrayed substantially in parallel and a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodiesand which bind the plurality of the linear bodiesin a state of being arrayed substantially in parallel. The linear bodieshave reflective surfaces which reflect light which is incident to the linear bodyalong a direction which intersects with a length direction of the linear bodyand refractive surfaces which refract the light. In at least a part of a planar structure body, the orientations of reflective surfaces of at least some of the linear bodies out of the plurality of linear bodiessubstantially match and the orientations of the refractive surfaces of at least some of the linear bodies substantially match.
