APPARATUS AND METHOD FOR HEAD UP DISPLAY

摘要

PURPOSE: A head-up display device and a method thereof are provided to adjust a view angle and to enlarge or reduce an image by adjusting a distance of forming a driving information image over a front window. CONSTITUTION: A head-up display device (100) includes a display panel (120), a first reflective mirror (130), a second reflective mirror (140), a first optical lens (150), and a second optical lens (160). The display panel outputs driving information by using light as a light source. The first reflective mirror is located in front of the display panel to reflect an image of the driving information downwardly at 7°. The second reflective mirror reflects the image of the information upwardly at 25°. The first optical lens transforms the image of the information reflected by the second reflective mirror according to a glass curvature state of a front window in order to output the same. The second optical lens projects the output image of the first optical lens to form an image over the front window.
