How Does a Heads-Up Display Work?

Heads-up displays are becoming quite popular today as they are less distractive for drivers. From navigation data to speed profiles, you’ll find it all on the windscreen. Dash screens have everything as well, but drivers need to lower their heads and take their eyes off the road for information.

This can cause slip ups or worse – accidents. Heads-up displays are the perfect solution to this problem.

Mechanism Behind the Heads-Up Display

Heads-up displays include a transparent display of information on the windshield. This data is reflected directly in the driver’s visual field so that they can focus on the road as well. The HUD system has a projector unit, combiner and a computer that generates a video of this information.

The HUD system works in two different ways.

The first system makes use of transparent phosphors which are embedded in a small section of the windshield to display information. The second system uses a reflective mirror section on the windshield. A light embedded in the dash is reflected onto this mirror and, in turn, on the windshield.

Current Status of the Heads-Up Display System

The rapid development of automation technology has brought forth the latest version of heads-up systems. Augmented reality (AR) is soon going to be used to display information on any surface. The information from the car’s GPS system, your phone’s internet and mobile applications will be displayed onto the windshield so that it becomes a viewing screen.

Benefits of Heads-Up Displays

HUD systems are now integrated with infrared cameras to detect any object in the drivers; field of view that is affected by darkness or fog. These objects can be projected on your windscreen the same as in real life. This can help you avoid collisions or accidents.

The HUD can also guide you regarding the best route in real time so that you can reach your destination safely and on time.

If you don’t already have HUD in your car, think about when the time comes to purchase a new vehicle.  It takes a little getting used to but once you have it, I think you’ll see the benefits.
