VEHICLE HUD DEVICE USING MULTIPLE LENSES

摘要

Disclosed is a vehicle HUD device using multiple lenses, in which optical properties of lenses and the arrangement of reflectors are enhanced to achieve improved sharpness and visibility of travel information images projected on a windshield of a vehicle. The vehicle HUD device using multiple lenses comprises: a liquid crystal panel for displaying travel information; a backlight unit arranged behind the liquid crystal panel to provide light; a plurality of reflectors for reflecting, sequentially along a specific path, travel information images displayed on the liquid crystal panel; and lenses for enlarging or contracting the travel information images reflected by the reflectors, focusing the images, and reflecting the images onto the windshield, wherein the lenses are one or more meniscus lenses which are sequentially arranged along the optical axis that is the same as the optical axis of the reflector arranged below the lenses, and which convexly protrude in the direction in which the travel information images are applied.
