Many manufacturers have started offering Heads-up Display as an option for buyers. These displays can project the information on the windshield, and they can show you all the required matrices on the windscreen. The data usually includes navigation, speed, information on road signs and other important information. Because of the HUD, you do not have to remove the eyes from the road.

The technology behind Heads-up Display

The HUDs have been an integral part of fighter jets since the mid-1950s. These screens were used for displaying information like the targets, speed, direction, altitude and aim sights for the pilot. You would have seen these HUDs while playing video games. The technology behind the HUDs in video games and fighter jets is very similar. A small project displays the information in front of the user on the windshield of the car. In most of the systems, the information includes GPS Navigation, Speed and Road Signs.

There are multiple technologies used in the HUD. The first one includes the use of phosphorous on the windshield that reacts to the laser shining on the screen. The phosphorous is transparent, and hence you get an unobstructed view when the laser is off. However, you can see the information when the laser is projected. Some systems may have an additional mirror for projecting the data.

Some cars come with a less expensive HUD system. In those systems, you have a mounting unit that can be mounted on the dashboard. This mount is connected to the car using a USB or using the OBD. The information is then projected on the windshield. Some of these systems also come with smartphone support that can help project the information. Lastly, you will also come across the HUD units that can be connected wirelessly, and the information can be displayed on the HUD.

Some systems have a widescreen mounted behind the windshield, and a project is used to project the image on the transparent screen. It works on the total internal reflection phenomenon. The screen works as a magnifying lens that flips the image and presents it to you. Here, a combiner comes in the picture to get you the content on the HUD.

In most cars, a button is integrated on the dashboard that can be used to turn on or turn off the HUD. This can help you in customizing the driving experience.

Evolution of the HUD

The HUDs have constantly been evolving, and the technology is getting better with every passing day. Some of the systems also use a LIDAR sensor and an Infrared scanner to track the hazards on the road. These vehicles are equipped with advanced radar systems to track all the treats. The technology is currently evolving, and one of the new integration includes the integration of AR technology to offer a safer experience to the users. The technology is constantly improving, and we are sure that we will see a lot of improvement in the HUD feature in the coming future.
