Compact high field of view display
A wide field of view display device employs curved optical components for enhanced performance with a compact arrangement. A wide field of view display includes a curved display device; a first curved lens having a display side and an exit side, wherein the display side is facing the curved display device; a first plurality of Fresnel facets disposed on the display side of the first curved lens; a second curved lens having a display side and an exit side, wherein the display side is facing the exit side of the first curved lens; and a second plurality of Fresnel facets disposed on the display side of the second curved lens, wherein the first plurality of Fresnel facets is configured to focus light from the curved display device on the second plurality of Fresnel facets, and wherein the second plurality of Fresnel facets is configured to focus light from the first plurality of Fresnel facets on a central image point.
Apparatus for displaying floating image and vehicular display module including the same
An apparatus for displaying a floating image is disclosed. The apparatus includes a light source that extends in a planar direction and emits light for realizing the floating image, a collecting lens, which extends parallel to the light source and refracts the light, a reflective plate, which faces the collecting lens and reflects the light that is refracted at the collective lens, and a dihedral reflector array, which extends in a planar direction and includes mirrors extending in directions intersecting each other, where a first surface of the dihedral reflector array facing the reflective plate such that the reflected light is incident on the first surface, and the reflected light is emitted from a second surface of the dihedral reflector array by being reflected by the mirrors, thereby realizing the floating image at a position spaced apart from the second surface.

OPTICAL DEVICE
An optical device includes a light guide plate configured to guide light within a plane parallel to an emission surface, and a plurality of light focusing portions to which the light guide plate guides directional light. Each of the plurality of light focusing portions is provided with an optical surface configured to create from the directional light incident thereon emission light in a direction substantially converging on a single convergence point or convergence line in a space or to create emission light that substantially diverges from a single convergence point of convergence line in a space and exits from the emission surface. The plurality of light focusing portions are provided near the emission surface of the light guide plate, and each of the plurality of light focusing portions is formed along a predetermined line within a plane parallel to the emission surface.
VEHICULAR SIGNAL AND DAYTIME RUNNING LIGHT ASSEMBLIES WITH UNIFORM ILLUMINATION
A vehicular signal assembly that includes an inner chamber defined by a substrate comprising LED light sources and spaced apart, corresponding Fresnel lenses; and an outer chamber defined by the Fresnel lenses and an outer lens comprising optical elements. The outer lens can have a width of at least 12 mm. Further, each LED source emanates incident light directly through the chambers to produce a light pattern with a contrast ratio of 3:1 or less, e.g., a daytime running light pattern. Each LED source can also emanate incident light directly through the corresponding Fresnel lens an outer lens to produce the daytime running light pattern.

Rear projection simulator with freeform fold mirror
The present invention provides a rear projection simulator system with a free-form fold mirror. The system includes a high definition projector and a curved screen. The free-form fold mirror is interposed between the projector and the screen. The free-form fold mirror includes one or more non-planar (e.g., curved) portions to eliminate or reduce loss of resolution of the projected image near the edges or boundaries of the image.
