HUD is a transparent display that is mounted on to the dashboard of the car and displays crucial information and data without diverting the driver from their usual viewing position. This new-age car tech gets its name from the position it allows the driver to be in. By this, we mean that the driver can be in straight heads up position and have access to all the vital information that they need to see while driving the car. Be it the car’s speed or the navigation, you can have it all on the HUD. Initially, they were designed to be useful for military aviation but have gradually shifted to cars and other automotive now.

Heads Up Display: Composition and Assembly

Commonly, an HUD is an optical collimator setup which consists of a convex lens or concave mirror with a cathode ray tube, light-emitting diode display, or liquid crystal display at its focus. An image is produced by this setup where the light rays are collimated. Confused? Read on! A collimated ray is a condition where the light rays are parallel to each other and do not diverge with distance. If the rays are not collimated properly, they will tend to diverge before reaching the source.

Coming to the main stuff now, the combiner is an angled flat piece of glass located in front of the viewer. This glass redirects the projected image in such a way as to see the field of view and the projected infinity image at the same time.

HUD Advantages
  • Helps you avoid turning your head to various places in search of different information. Be it speed or navigation, you have it all at a single place i.e. on the HUD.
  • Eyes tend to re-focus faster on the road when you take your eyes off the HUD.
  • You get all the information that you need while driving at a single place so you are not distracted from the road by your mobile or those fancy dials in the MID.
  • Significantly reduces driver’s fatigue because they don’t have to struggle looking for information inside the car and can focus more on the road.

Disadvantages of having a HUD

HUD Disadvantages
  • More development is required. Each and every vehicle cannot have HUD because they don’t have the required controls making it a hard to implement the technology.
  • It significantly adds on to the cost of the vehicle. If the brand decides to make it a standard feature, they will have to put in money.
  • Rather than being a convenience, this can be a distraction to some as well. Yes, some drivers don’t prefer using the HUD because they feel that the display distracts them rather than providing them with any useful information.
