DRIVE
September 20, 2023
The present invention relates to a head-up display for a vehicle, comprising a mirror unit comprising a first mirror for reflecting first and second image lights toward a windshield of the vehicle; wherein the mirror unit comprises: an image generator configured to emit light linearly-polarized in a first direction, and light linearly-polarized in a second direction orthogonal to the first direction; a second mirror disposed to be separated from the first mirror so as to transmit the light linearly-polarized in the first direction, and reflect the light linearly-polarized in the second direction to the first mirror; a third mirror disposed to be separated from the second mirror so as to reflect the light linearly-polarized in the first direction that has transmitted through the second mirror to the first mirror; a display layer located at the windshield of the vehicle to display a first virtual image corresponding to the first image light in a first region, and display a second virtual image corresponding to the second image light in a second region; and a controller configured to reflect the first image light and second image light toward the windshield to display the first virtual image and the second virtual image, wherein the first virtual image and the second virtual image have different depths of view.
