Definitions
- the shape of the virtual image display surface PS is distorted in the front-rear direction due to the influence of the curved surfaces of the windshield 2 and other optical systems (for example, the curved mirror 171 shown in FIG. 3B). , along with this, the displayed image (virtual image) is also distorted.
- FIG. 3A is a diagram showing the principle configuration of a 3D display device
- FIG. 3B is a diagram showing an example of image display by the 3DHUD.
- the virtual image display surfaces PS1 and PS2 are curved under the influence of the curved shape of the projection target member (windshield) 2, which is the largest factor in image distortion.
- the image is distorted in the longitudinal direction (depth direction) of the vehicle.
- the curved surface display portion 210 has a bent shape (cross-sectional shape that has been bent) by approximating the arcuate curved shape of the windshield 2 . have. Therefore, the influence of the curvature of the windshield 2 is canceled out, and the difference in optical path length of each light beam is sufficiently reduced.
- the viewer's weighting is set so as to satisfy the relationship S10>S20>S30.
- curved display unit for example, various display devices such as a micro LED display device, a liquid crystal display device formed on a flexible substrate, an organic EL display device, and the like can be used.
- a curved display with a fixed shape can also be used.

Abstract
Le but de la présente invention est de supprimer une distorsion d'image qui se produit en raison de la forme d'un élément de réception de projection (par exemple, un pare-brise ou similaire) lorsque la plage d'une boîte à œil est augmentée dans la direction de la largeur d'un véhicule. Ce dispositif d'affichage tête haute a une partie d'affichage à surface incurvée déformable (210) qui est montée sur un véhicule, affiche une image, et est flexible, et un système optique pour projeter une lumière d'affichage pour une image affichée par la partie d'affichage à surface incurvée (210) sur un élément de réception de projection (2) disposé sur le véhicule, la partie d'affichage à surface incurvée (210) a une pluralité de régions d'affichage (R10, R20, R30) disposées adjacentes l'une à l'autre le long de la direction de la largeur du véhicule, et la forme de la partie d'affichage à surface incurvée (210) est déformée en fonction de la forme incurvée de l'élément de réception de projection (2) dans l'espace de façon à supprimer les différences de longueur de trajet optique de la lumière d'affichage d'images correspondant à des régions d'affichage respectives à des boîtes à œil (EB10, EB20, EB30) correspondant à des régions d'affichage respectives.
