<p>The present invention relates to a high brightness head-up display device to provide an image 2 to 320 times as bright as an image of an existing structure. To achieve this, a spherical translucent mirror is provided at the inner top of a case, wherein a projector unit is provided at the bottom. A spherical reflective screen is provided in the front side of the projector unit. The projection distance of the projector unit and the focal length of the spherical reflective screen are configured to be identical. The spherical translucent mirror is provided in the front side of the spherical reflective screen. A space between the spherical translucent mirror and the spherical reflective screen is placed in the focal length position of the spherical reflective screen. A barrier film on the rear side of the spherical translucent mirror blocks outdoor daylight and allows the outside to be seen from the inside for more than 80%.</p> |
