HEAD-UP DISPLAY DEVICE AND BACKLIGHT DEVICE |
摘要 |
A head-up display device includes: a light source that emits light; a condenser that condenses the light emitted from the light source in a first direction; an adjuster that adjusts the light emitted from the condenser; a first reflector that reflects the light emitted from the adjuster in a second direction different from the first direction; a display that includes an image display surface forming a display image and emits a display light representing the display image with the image display surface transmitting the light reflected by the first reflector; a second reflector that reflects the display light being emitted from the display and being incident from above; and a third reflector that reflects the display light incident from the second reflector to the projection member. The adjuster adjusts the light emitted from the condenser according to a size of the image display surface. |

1. A head-up display device in which display light representing a display image is projected to a projection member so that an occupant visually recognizes the display image, the head-up display device comprising:
a light source that emits light; a condenser that condenses the light emitted from the light source in a first direction; an adjuster that adjusts the light emitted from the condenser; a first reflector that reflects the light emitted from the adjuster in a second direction different from the first direction; a display that includes an image display surface forming the display image and emits the display light with the image display surface transmitting the light reflected by the first reflector; a second reflector that reflects the display light being emitted from the display and being incident from above; and a third reflector that reflects the display light incident from the second reflector to the projection member, wherein the adjuster adjusts the light emitted from the condenser according to a size of the image display surface. |
