Abstract
A vehicle display device includes a housing mounted in a vehicle and having a light-shielding outer wall that forms an accommodation space, a slit being formed in the outer wall, a three-dimensional display surface disposed in the accommodation space and on which a real image is formed by display light, a projector disposed in the housing and configured to project the display light onto the display surface, and a reflector disposed outside the housing and having a reflection surface configured to reflect the real image toward an eyepoint in the vehicle. The shape of the reflection surface is a recessed shape such that light rays of the real image intersect in an optical path extending from the display surface to the reflection surface through the slit.
Claims12
A vehicle display device comprising:
- a housing mounted in a vehicle and having a light-shielding outer wall that forms an accommodation space, a slit being formed in the outer wall;
- a three-dimensional display surface disposed in the accommodation space and on which a real image is formed by display light;
- a projector disposed in the housing and configured to project the display light onto the display surface;
- and
- a reflector disposed outside the housing and having a reflection surface configured to reflect the real image toward an eyepoint in the vehicle, wherein
- a shape of the reflection surface is a recessed shape such that light rays of the real image intersect in an optical path extending from the display surface to the reflection surface through the slit, and
- wherein the slit is narrower at an outside of the housing than at an inside of the housing, wherein
- the slit extends along a vehicle width direction, and
- the reflection surface is shaped such that the light rays of the real image intersect in a vehicle height direction and do not intersect in the vehicle width direction, wherein a surface of the outer wall where the slit is formed constitutes an upper surface of an instrument panel of the vehicle, and
- the reflector is disposed above the upper surface,
- wherein the three-dimensional display surface is within the housing, comprises a convex surface of which the display light from the projector is reflected to a concave surface of the reflector, and of which the convex surface of the three-dimensional display surface is facing the concave surface of the reflector with the slit arranged therebetween.

- a shape of the reflection surface is a recessed shape such that light rays of the real image intersect in an optical path extending from the display surface to the reflection surface through the slit, and
- wherein the slit is narrower at an outside of the housing than at an inside of the housing, wherein
- the slit extends along a vehicle width direction, and
- the reflection surface is shaped such that the light rays of the real image intersect in a vehicle height direction and do not intersect in the vehicle width direction, wherein
- a surface of the outer wall where the slit is formed constitutes an upper surface of an instrument panel of the vehicle, and
- the reflector is disposed above the upper surface,
- wherein the light rays of the real image intersect in the vehicle height direct and within the slit.
