LCD – situated under the dashboard, this display shows the information you will see on the windshield or glass. The screen is sometimes flipped because you will see a mirror reflection of it.
Series of mirrors – used to magnify the image from the display. Some manufacturers use more mirrors to flip the image, while some flip the image on the screen via software. Depending on the model, the mirrors can be motorized. Thanks to that, the driver can better position the image on the windshield (up and down). This way, shorter and taller drivers can adjust the reflected image according to their height.
Glass with a transparent film – The film is important because the windshield has more layers on it and the HUD may project a duplicate picture. The best car heads up display kits come with a glass or plastic part that has the film already applied[source].
