Everything You Need to Know About Head up Displays for Cars

Being in a position to clearly see where you’re going is very important when it comes to driving. Head up displays are designed to help us on the road by ensuring that we don’t miss anything, from speed to directions to important turns. Keeping our eyes on the road instead of down at a small screen also helps keep us safe by ensuring important information is always in our line of sight. They allow drivers to keep their eyes forward, which means they will able to react more quickly if a collision might be imminent.

But what exactly are head up displays for cars and how do they work?

How do head up displays work?

Head up displays make use of augmented reality technology to project important data about your car or your surrounding on a display (mostly on the windshield) to ensure that you don’t look away when driving.

Depending on the type of HUD, data is projected on the windshield to notify you where and when to turn, provide restaurant information, inform you about the proximity of the car ahead of you, the condition of your engine, your speed, and to inform you what time it is among other crucial information.

Thanks to head-up display technology, you don’t need to sneak a quick look down at your gauge cluster to see your speed anymore since this information can be projected on your windshield at eye level. The technology used in head-up displays is futuristic and makes you feel like you’re in the cockpit of a fighter jet or spaceship.

Most HUDs make use of a set of innovative and transparent phosphors that react and then display data about your car and its surroundings on the windshield each time lasers shine on them (transparent phosphors). Other HUD systems for cars rely on the same technology but integrate mirrors or screens to help them display crucial data on your windshield.

HUDs are no longer gadgets for high-end cars. Since 2012, different brands have been manufacturing quality aftermarket head-up displays for customers looking to include this technology in their cars.

The best part is that aftermarket head-up displays are easy to install. The gadget is mounted on the top of a vehicle’s dashboard so that it can easily project important vehicle data on the clear windshield. Additionally, these gadgets are able to connect to mobile devices inside the car via Bluetooth.

Why do you need this gizmo, you ask? In addition to being a trendy technology, it will help minimize the distractions caused by your mobile devices. It does so by displaying your directions, notifications, messages, and incoming calls on the clear windshield in front of you.

What are HUDs for?

HUDs are gadgets that rely on an innovative technology to project data onto the windshield of your vehicle. Plugged into your car’s OBD port, it can relay important information like your vehicle’s speed, temperature, RPMs, and more. Paired with your phone via Bluetooth, they can also show you notifications, navigation instructions or even who might be calling you.

Since this technology has the capability to display important data on your windshield, it considerably trims down the amount of time you divert your attention to steal a look at your speed, the radio, or phone while driving. Because your eyes will be on the road more of the time, you are less likely to cause or get involved in collisions.

Are HUDs safe?

HUDs are no longer a rare thing. Although manufacturer-installed HUDs used to only be available in higher-end luxury cars like BMWs, Mercedes-Benzes, and Audis, they can now be found in even Mazda, Honda, and Hyundai cars.

Hyundai Kona HUD

Consumers are now able to purchase aftermarket HUDs to install in their older cars. However, are HUDs safe?

Although the idea behind HUDs has been warmly welcomed by most consumers, some users have criticized the technology, saying that it causes more distractions than it can prevent.

A study conducted by the University of Toronto found that HUDs might not be as safe as most people think. The researchers say that the technology relies on a multi-tasking technique that could be dangerous because human beings are easily distracted and aren’t that good at multi-tasking.

The problem with all the information or alerts that HUDs give drivers, according to researchers from the University of Toronto, is in the manner in which it is delivered. Although this data is delivered at an eye level, it occurs in a manner that is more distracting than actually useful.

Most of the time, drivers are not in a position to absorb all of this data at once. They find themselves at crossroads between interpreting all this data or responding to it and keeping their eyes on the road.

According to Ian Spence, a professor of Psychology at the University of Toronto, HUDs are dangerous because they make drivers split their attention (which means not focusing on the road) in an effort to understand the additional visual data on their windshield.

This means that in addition to keeping their eyes glued on the road, drivers also have to pay attention to the various pop-ups displayed on their windshield.

Choosing the right HUD for your car

Are you trying to figure out which aftermarket head-up display is ideal for your car? Understanding the different types of HUDs currently available in the market, their compatibilities, as well as the available connectivity options, can help you make informed decisions. The following list of aftermarket car HUDs will give you a comprehensive idea of what to expect and what to look for when shopping for an HUD.

Navdy HUD Review

What to look for when buying an aftermarket HUD

Aftermarket HUDs are available in two types, namely screens and projections. In most cases, HUDs that come with their own screen are better, as they don’t require using a film on your windshield. This is because screens allow easier repositioning so drivers can customize it to their seating position. Furthermore, HUDs that come with their own screens are less associated with “double image” and are highly priced.

All the same, the material used to create the screen plays a key role in determining whether the “double image” will occur or not. In general, you want an HUD that is easy to install, is compatible with your phone and car, and shows the information you deem useful. Beware of cheap offerings because you get what you pay for.

Problems and solutions

You must be willing to spend more money if you want the best HUD. One issue with HUDs, especially projection HUDs, is image quality. Although projection HUDs have some good image quality, this might change at night when there isn’t enough light.

Additionally, during the day, images on projection HUDs might be washed out especially when driving towards the direction of the sun. Also, “double vision” is more prevalent in projection HUDs than it is in dedicated screens. The scope of the “double vision” is most of the time influenced by the type of glass used in the windshield, how the windshield is constructed, and the film material.

Sometimes sticking a small film on the windshield can help reduce image washing out that occurs during the day. However, figuring out the right place to stick the film isn’t easy and requires a lot of trial and error.

In addition, some films might be sticky although this greatly depends on the HUD. A sticky film is difficult to remove from the windshield and frequent repositioning might minimize its adhesiveness.

Connectivity and information

Connectivity in most HUDs is by means of wires. This kind of connectivity allows HUDs to display the performance of the vehicle. Furthermore, a 12-volt outlet situated on your vehicle’s dashboard powers most HUDs. However, HUDs that connect to mobile devices need an additional connectivity outlet.

Most of the time, the type of data displayed is impacted by the ability of your HUD to connect to your mobile device. HUDs without the mobile phone connection feature only receive data such as engine temperature, RPM, and speed from the car. On the other hand, HUDs that have the mobile phone connection feature may offer additional functionalities such as directions as well as third-party application.

Display quality

Display quality is all about brightness, cohesion, and resolution. When choosing a HUD for your car, you need to go for one with the best cohesion. This is simply the HUD that is less prone to double image. In most cases, double image is brought about by polarized windshields.

LED HUDs provide the best brightness. However, brightness in HUDs may depend on where the information is displayed whether on a film or dedicated screen. The same factors that affect brightness affect resolution.


Go for HUDs that come with the mobile phone connectivity feature. If the HUD supports third-party applications, the better. However, note that most HUDs with the mobile phone compatibility feature only use specific third-party applications and might be unresponsive if a different application is used.

Cars come with varied readout systems such as EOBD, OBD, OBDII, and JOBD; therefore, it is smart to consider your type of vehicle when choosing a HUD. If the readout system of your car doesn’t match your HUD of choice, chances are you won’t be able to receive vital data about the performance of your car.

Our Final Verdict

Collisions occur when drivers are checking their phones and forget that they are driving. However, HUDs have changed the way we receive notifications from our cell phones while behind the wheel. If you install a HUD in your car, you’ll no longer need to constantly check your mobile device when driving since all notifications will be displayed on your windscreen.

The main function of an HUD is to make sure that your eyes are on the road at all times. In addition to having some amazing interactive features, most HUDs for cars come with voice command features that make them even cooler and more functional. Not only do these command features make driving fun, they also make it easy and eliminate distractions.
