3.1 Types of AM-HUD
There are several implementations of aftermarket HUD products. These different design approaches are broadly classified into the following categories:
Projector HUD
A Projector HUD creates an image on a diffuser screen with no additional optics after the projector (Figure 1).
Figure 1. Projector HUD Teleprompter HUD
A Teleprompter HUD allows indirect viewing of an image through partial reflection from the car’s windshield, or a partially reflective screen in front of the windshield (Figure 2).
Figure 2. Teleprompter HUD Augmented HUD
An augmented HUD uses mirror optics to create a virtual image floating beyond the windshield (Figure 3).
