Title:
HEAD-UP DISPLAY, HEAD-UP DISPLAY SYSTEM, AND MOVING BODY
Document Type and Number:
WIPO Patent Application WO/2019/160160
Kind Code:
A1
Abstract:
This head-up display is provided with a display surface, an optical element, a projection optical system, and a controller. The display surface has a plurality of sub pixels. The plurality of sub pixels are arranged, in a grid pattern, in a first direction and a second direction approximately perpendicular to the first direction. The display surface has a plurality of band-shaped regions. The plurality of band-shaped regions extend in a defined direction on the display surface. The optical element defines the beam direction of image light for each of the plurality of band-shaped regions. The image light is emitted from the sub pixels. The projection optical system reflects the image light to form a virtual image of the image displayed on the display surface. The controller controls the display surface. The band-shaped regions include a first visible region and a second visible region. In the first visible region, the beam direction is defined by the optical element such that image light that reaches a first eye of a user is emitted. In the second visible region, the beam direction is defined by the optical element such that image light that reaches a second eye of a user, different from the first eye, is emitted. The controller displays a black image on first sub pixels, at least a portion of which are included in the first visible region. The controller performs a control so that an image displayed on a portion of second sub pixels, at least a portion of which are included in the second visible region, can be switched between the black image and an observation image having an arbitrary luminance.
