What does a head up display do and is it necessary?

The legendary HUD, after being installed, makes the car full of technology.

The impact is that driving is more convenient and cool, and the sense of science and technology is full. The HUD simply reads the data from the car's system and projects it onto the windshield without any ill effects.

The HUD head-up display is actually equivalent to a driving assistance system, mainly to project some driving information directly to the front windshield, or directly project the information onto a transparent screen, the driver does not need to look down at the dashboard and other data during driving, as long as he looks ahead, he can see the relevant driving information, which greatly improves driving safety.

As for whether the HUD head-up display is practical, it depends on the owner personally, although the original intention of the HUD design is to assist driving and improve driving safety, but the use effect in actual life is not so ideal, and some car owners have previously reflected in the process of using the HUD head-up display, because the information is directly projected onto the front windshield, the surrounding line of sight is restricted, it looks very uncomfortable, and it takes a while to get used to it.

Not only that, directly projecting the driving information onto the front windshield will inevitably attract the driver's attention too much, causing the driver to be distracted and reduce the observation of road conditions, and a little attention will cause unnecessary traffic accidents due to distraction.

Therefore, the original intention of the invention of the HUD head-up display is for safety, but the specific use effect is still based on the individual, it is recommended that the driver must pay more attention not to be distracted when using the function during driving, and at the same time, the function only plays a role in assisting driving, or can not rely too much on the function.

Pros and cons of head-up displays for cars

1. Benefits

to improve convenience

The head-up display projects driving information directly onto the front windshield, so that the driver does not have to look down to see the driving status of the car, thus avoiding distracting the driver from the road ahead.

and reduce driver fatigue

The use of the car's head-up display also eliminates the need for the driver to look back and forth on the dashboard information and the road conditions ahead, and the ridge relieves the driver's eye strain.

Second, the cons

Some users find it difficult to adapt

Many car owners say that they are not used to the head-up display system, because so much driving information appears on the vehicle screen at once, and it is easy to distract the driver when driving, which may cause accidents due to lack of concentration.

It is expensive

The cost of a car head-up display is very expensive, and the first of a display needs thousands of yuan, so at present, only a few high-end models are installed with the system.

, the quality is uneven

At present, the market is mixed with hundreds of yuan and other products of poor quality, if consumers do not understand the situation, it is easy to buy inferior products, which not only causes economic losses, but also has potential safety hazards.

1. Meaning: The head-up display is referred to as HUD, also known as the head-up display system, which refers to the driver-centered, blind operation, and multi-functional instrument panel. 2. Function:

The HUD can project information such as current speed and navigation onto the photoelectric display device on the windshield to form an image in front of the glass. Drivers don't need to turn their heads or look down to see navigation and speed information. 3. Type:

It is divided into suspended HUD and instrument panel HUD. The suspended HUD is fixed to the sun visor above the driver, so that the HUD information is projected on the upper part of the windscreen. The instrument cluster HUD is fixed on the center console of the driver's previous mask, which determines that the HUD information will be projected in the front area of the windshield.

A head-up display is necessary. A car head-up display allows the driver to see information without having to look down, avoiding distractions from the road ahead. Drivers don't have to adjust their eyes between looking at distant roads and nearby gauges, which avoids eye strain.

Such systems are expensive and are currently only used in a few premium cars. @2019

There is also a collection on the Internet about whether a head-up display is necessary. Information about head-up displays is necessary. Let's share it with you.

1.Yes. The HUD head-up display allows the driver to look down at the information and thus avoid being distracted by the road ahead.

Drivers can adjust their eyes by observing the road in the distance and nearby instruments to avoid eye strain. This system is expensive and is currently only used on a few high-end cars.

The use of projection technology to project navigation and other information onto the windshield, so that the driver can look down at the relevant information, so as to observe the road ahead and the surrounding vehicles more attentively, reduce the driver's frequent look up at the distant road and look down at the navigation switch caused by the visual fatigue, so as to improve driving safety, especially at night and at high speed.

It can display the current speed, navigation information, driving assistance information, warning signals and other information. The information displayed without the fiber code is limited. In addition, there are some problems with the HUD, especially during the day, and HUD technology is actively solving such problems.
