Abstract: A head up display arrangement for a motor vehicle includes an image source emitting a light field. A first freeform mirror is positioned to provide a first reflection of the light field. A generally concave second freeform mirror is positioned to receive the first reflection and provide a second reflection of the light field. The second reflection is reflected off of a windshield of the vehicle so as to be visible to a driver of the vehicle as a virtual image. The generally concave second freeform mirror includes a reflective surface having a shape such that the virtual image appears to be curved to the driver of the vehicle.

Abstract: A head up display arrangement for a motor vehicle includes a head up display module having a picture generation unit emitting a light field. A polarizing device is rotatable between at least a first rotational position and a second rotational position. The polarizing device receives the light field from the picture generation unit and emits the light field regardless of whether the polarizing device is in the first rotational position or the second rotational position. More of the light is emitted by the polarizer in a P-polarization state in the second rotational position than in the first rotational position. A windshield reflects the light field from the polarizing device such that the reflected light field is visible to a human driver of the motor vehicle as a virtual image.

The optically reflective coating of the printed circuit board reflects the light reflected by the liquid crystal display back to the liquid crystal display. At least one mirror reflects light passed by the liquid crystal display toward a windshield of the motor vehicle such that the light is reflected by the windshield and is visible to the human driver as the virtual image.

Abstract: An example device includes a heads up display (HUD) to guide light towards a user in a vehicle. The device includes a HUD housing with a base plane and a stationary mirror mount on the HUD base. The device includes an adjustable mirror mount on the HUD base and an attachment slot disposed in the HUD housing, the attachment slot to accept a mounting tab. The attachment slot is shaped to accept either one of a predominantly vertical mounting tab and a predominantly horizontal mounting tab. The predominantly vertical mounting tab includes a first portion that projects horizontally from a sidewall of the HUD. The first portion includes a first end inserted into the attachment slot and a second end opposite the first end. A second portion is coupled perpendicularly to the second end of the first portion. The second end extends parallel to the sidewall of the HUD.
