Components used –
Heads up display comprises of a projector unit which is an optical collimator setup that includes a convex lens or concave mirror with a cathode ray tube light emitting diode display or liquid crystal display at its focus.
Second component used is the combiner which is typically an angled flat glass that redirects the projected image from projector in such a way as to see the field of view. Combiners may have special coatings that reflect the monochromatic light projected onto it.
And the very last component used is the computer that provides the interface between the HUD (i.e., the projection unit) and the systems/data to be displayed and generates the images and symbols to be displayed by the projection unit.

The feedback offered by an HUD is projected onto the windshield of a vehicle with the aim of integrating outside stimuli and the instrumental feedback; thus, removing the need to remove a driver’s eyes from the road The reaction time to hazards in HUD are faster compared.
