What does Head-Up Display mean?

Head-Up Display, abbreviated as HUD, is also known as the Head-Up Display System. It refers to a multifunctional instrument panel centered around the vehicle driver, designed for blind operation. Specific details are as follows: Function of Head-Up Display: It projects important driving information such as speed and navigation onto the windshield in front of the driver. The HUD can project current speed, navigation, and other information onto the photoelectric display device on the windshield, forming an image in front of the glass. The driver can see navigation and speed information without turning or lowering their head. Types of Head-Up Display: The distinction between suspended HUD and dashboard-mounted HUD is mainly based on the mounting method. Suspended HUD is fixed on the sun visor above the car driver, which results in the HUD information being projected onto the upper area of the windshield. On the other hand, dashboard-mounted HUD is fixed on the dashboard in front of the driver, which means the HUD information will be projected onto the front area of the windshield.
The head-up display (HUD) allows drivers to see important information directly on the windshield without having to look down at the dashboard. I experienced it once in a friend's car—the navigation arrows looked so cool, as if they were floating on the road. This technology was originally used in fighter jets and is now available in regular cars, mainly displaying three types of information: speed, speed limits, and navigation routes. There are two projection methods: one projects directly onto the windshield, which requires a special film, and the other uses a built-in small reflective screen. The benefit is that drivers don’t need to take their eyes off the road, making it especially useful in poor visibility conditions like rain or fog. On long drives, it also prevents neck strain from frequently looking down.
