Abstract: A head-up display projects an image onto an eye-box of an observer. The head-up display includes a plurality of light source elements, liquid crystal panel, first lens, viewpoint detector, and controller. The plurality of light source elements are arranged into an array shape to output light beams. Liquid crystal panel displays the image, and first lens deflects the light beams emitted from the plurality of light source elements such that an identical region in an incident plane of liquid crystal panel is illuminated with the light beams. Viewpoint detector detects a viewpoint position of the observer. Controller controls light intensity of the light source elements according to the viewpoint position detected by viewpoint detector.

Abstract: A head-up display includes: a plurality of light source elements which are arranged in a first direction and emit light; first lens which takes in from an incident surface the light emitted from the plurality of light source elements and emits the light from an emission surface; diffusion member disposed on a side of the emission surface of the first lens; a spatial light modulation element which takes in from an incident surface the light having been emitted from the plurality of light source elements and having passed through first lens and diffusion member, modulates the taken-in light in accordance with image information, and emits the modulated light from an emission surface; and an optical element which reflects the light emitted from spatial light modulation element. First lens changes an optical path of light emitted from each of light source elements such that the light emitted from the each of light source elements reaches the same area on the incident surface of spatial light modulation element.

Abstract: Head-up display includes display device and projection optical system. Display device displays an image. Projection optical system includes refraction lens. Projection optical system projects the image displayed on display device to an observer. Refraction lens is disposed while inclined with respect to a reference beam. An incident surface of refraction lens is a concave surface relative to a side of display device in an X-axis direction. A curvature in a Y-axis direction of the incident surface is smaller than a curvature in the X-axis direction.

Abstract: A head-up display includes an optical system that radiates light forming a projected image toward an eye box. The eye box is a predetermined range in which eyes of an observer are assumed to be present. The optical system includes a Fresnel lens having a bumpy surface having a sawtooth-shaped cross-section. The bumpy surface is formed concentrically around an optical axis, and formed by alternately disposing first surfaces as light condensing surfaces that allow incident light to converge toward a focal point, and second surfaces as wall surfaces that do not allow the incident light to converge toward the focal point. The second surfaces are inclined with respect to the optical axis of the Fresnel lens at an angle to reflect the incident light striking the wall surfaces, in a direction toward outside of a range of the eye box.
