A lighting device includes light sources and a light guide plate. The light guide plate includes a base portion and a light collecting portion. The base portion includes a light entering surface and a light exiting surface. The light collecting portion protrudes from the light exiting surface. The light collecting portion includes light collecting sections elongated in a first direction parallel to a normal direction to the light entering surface and arranged in a second direction perpendicular to the first direction. The light collecting sections perform linearity adjustment to rays of light so that the rays of light travel along the first direction. The light collecting sections include first light collecting regions and second light collecting regions. The second light collecting regions perform the linearity adjustment at a degree greater than a degree of the linearity adjustment by the first light collecting regions.

Lighting device and display device

A lighting device includes light sources arranged in a row in an arrangement direction, alight guide plate disposed to cover the light sources and including a plate surface facing the light sources and an opposite plate surface opposite from the plate surface, and a light diffusion portion. A portion of the plate surface is a light entering surface and the opposite plate surface is a light exit surface. The light diffusion portion extends in the arrangement direction of the light sources and on the light exit surface such that a portion of the light diffusion portion overlaps the light sources. The light diffusion portion applies a diffusion effect to light that is within the light guide plate so as to travel in a direction crossing the arrangement direction and to be away from the light sources seen from a normal direction of the light exit surface.

Lighting device including light guide plate and display device including the lighting device

First and second prism sheets have pluralities of first and second unit prisms, respectively, arranged along a first direction and extending along a second direction, each of which has a base that is parallel to the first direction and a pair of oblique sides standing from both ends, respectively, of the base, and an angle that a second LED facing oblique side, which is one of the oblique sides that faces toward the LED, forms with respect to the base in the first direction in the second unit prism is smaller than an angle that a first LED facing oblique side that faces toward the LED forms with respect to the base in the first direction in the first unit prism.

An imaging module that generates a plurality of display images respectively based on a plurality of pieces of state information different from each other, in accordance with an instruction signal from a controller, and allows the plurality of display images to be displayed simultaneously on a display screen of a liquid crystal display device, and a recording and reproducing unit that performs a capture operation, in accordance with the instruction signal from the controller are provided. The recording and reproducing unit records the display screen on the recording medium as screen data through the capture operation.

Display control device, information display system for moving object, module for driver's seat and moving object

An on-vehicle instrument panel display system preferably is mounted on an automobile and operative such that a plurality of pieces of information including information relating to an automobile are converted into images and the images are displayed all on a liquid crystal panel. The on-vehicle instrument panel display system has a vehicle system, an amenity system, and a safety system, each of which creates data for displaying the images. Further, the on-vehicle instrument panel display system has an instrument panel image composition/output section which combines data created by the systems and outputs the result as composed image data to the liquid crystal panel. The instrument panel image composition/output section includes an image composition LSI. Composed image data outputted from the image composition LSI is an RBG signal or a YUV signal.
