  • Patent number: 11961059
    Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.

  • Patent number: 10578922
    Abstract: This invention reduces or prevents a phenomenon where a screen close to a light source becomes yellowed. A liquid crystal display device includes a liquid crystal display panel and a backlight. The backlight includes a light guide plate 10 and white LEDs 21 arrayed in a first direction on a plane of incidence 11 of the light guide plate 10. The white LEDs 21 each includes, in the first direction on a light-emitting surface, a central area occupied by a blue spectrum more densely than at adjacent sides of the central area. Incident plane protrusions 111, each extending in a thickness direction of the light guide plate 10, are formed on a section corresponding to the area having the dense blue spectrum of each LED 21, at the plane of incidence 11 of the light guide plate 10.

    Abstract: A display device includes a prism sheet between a display cell and a light guiding plate. The prism sheet includes a plurality of prisms having a constant apex angle continuously arranged in a second direction on a surface thereof opposed to a light-exiting surface of the light guiding plate. Each of ridge lines of the prisms extends in a first direction. Each prism has a first inclined face on a side on which light from the light guiding plate is incident and a second inclined face on a side reflecting the incident light. An area of the first inclined face is made smaller than an area of the second inclined face, and an area of a light-emitting region in the prism sheet is made larger than an area of a non-light-emitting region.

  • Patent number: 9194994
    Abstract: A liquid crystal display device includes: a light guide plate including a front surface, a back surface and an edge surface, the light guide plate being arranged such that the edge surface faces a light source, the light guide plate internally reflecting light incident from the edge surface and causing surface emission from the front surface; a liquid crystal display panel; and a reflective sheet arranged so as to face the back surface of the light guide plate. The back surface includes a first portion and a second portion. A surface of the second portion is located at a position recessed relatively from a surface of the first portion. The surface of the first portion is a rough surface. The surface of the second portion is a smooth surface. The reflective sheet is in contact with the first portion but avoids contact with the second portion.

  • Patent number: 8992062
    Abstract: Provided is a display device including: a light guide plate arranged so that an edge surface thereof is opposed to a light source, the light guide plate being configured to internally reflect light entering from the edge surface to cause planar light emission from a front surface of the light guide plate; and a reflective sheet arranged so as to be opposed to a rear surface of the light guide plate. Irregularities are formed on the front surface. The irregularities are formed to have a shape of a combination of first convex portions and second convex portions, each of the first convex portions including a first ridge line which continuously extends along a first direction corresponding to a light traveling direction, each of the second convex portions including a second ridge line which continuously extends along a second direction intersecting the first direction.
