Abstract
A head-up display includes a light source unit including first light source elements emitting lights of a first luminescent color and second light source elements emitting lights of a second luminescent color. The head-up display includes a first lens, a diffusion member, a spatial light modulation element that modulates the light emitted from the light source unit and transmitted through the first lens and the diffusion member, and an optical unit that projects the light emitted from the spatial light modulation element. The first lens changes an optical path of the light emitted from the light source unit, and the lights emitted from the first light source element and the second light source element are superimposed in a predetermined region on the incident surface of the spatial light modulation element.
Claims18
A head-up display comprising:
- a light source unit including at least one or more first light source elements emitting lights of a first luminescent color and at least one or more second light source elements emitting lights of a second luminescent color different from the first luminescent color that are arranged side by side in a first direction;
- a first lens including an incident surface through which the light emitted from the light source unit enters and an emission surface from which the incident light emits;
- a diffusion member disposed at a side of the emission surface of the first lens;
- a spatial light modulation element that includes an incident surface through which the light emitted from the light source unit and transmitted through the first lens and the diffusion member enters, modulates the light with image information, and makes the light emit from an emission surface;
- and
- an optical unit that projects the light emitted from the spatial light modulation element, wherein
- the first lens changes an optical path of the light emitted from the light source unit, and the lights emitted from the first light source element and the second light source element are superimposed in a predetermined region on the incident surface of the spatial light modulation element.
