Does a head up display work, does a head up display work

The main purpose is to make the driver more direct and convenient to observe the driving information, so as to reduce the number of heads down and turns, so as to avoid accidents caused by blind driving.

The head-up display, also known as the usual display, was originally used as an auxiliary instrument on aircraft, and has also begun to be installed in automobiles. The head-up display mainly uses the principle of optical reflection to reflect the information on the dashboard on the windshield in front of the driver. Drivers can see important information such as time, speed, navigation, and driving diagnostics without having to look down, so they can better concentrate on driving and help ensure driving safety.

As soon as China's "head-up display" came out, mobile phone navigation was not popular.

The car head-up display is of course useful, being able to project the screen onto the front windshield of the car for easy observation:

1. The head-up display is developed for high-speed vehicles, and when driving at high speed, especially at night when driving at high speed, in order to avoid the driver looking down at the watch or looking at the sound display, it may cause an accident due to failure to take effective measures before the emergency occurs;

2. The head-up display is a very meticulous care at a critical moment, and the technology projects the important information displayed by the instrument (such as vehicle speed) on the front windshield during the driving of the car, so that the driver does not have to bend down to look at the information on the instrument;

3. The head-up display can not only help novices who lack experience in speed judgment to control their speed, avoid speeding and violations in many speed limit sections, but more importantly, it can enable the driver to take instant readings under the condition that the large field of view does not shift, and always keep a clear mind to maintain the best observation state.

Precautions. 1. Fix the position of the head-up display host.

Then tear off the film on the surface of the host, find a position under the front windshield to put the host base, and put ** depending on your preferences. Then put the position, and the 3m glue is fixed.

2. Paste anti-ghosting film.

At this time, the projection seen on the glass will have a very serious ghosting. The solution is to put an anti-ghosting film on the projection position.

Personally, I think it's still very useful, it's very helpful for driving, I bought a head-up display for escort road babies, I have used it for two years, I don't use it now, it's really a little unaccustomed, the most important thing is that the solar energy does not need to be wired, the speed time is still GPS measurement, and I feel very good.

The car head-up display is also called the car headup display (headupdisplay), referred to as HUD1. It is developed for high-speed vehicles, especially at high speed at night, in order to avoid the driver bowing his head **instrument display or **audio display, in case of emergency in front of him, it may be too late to take effective measures and cause accidents. 2. The HUD is at the critical moment to reflect the extremely delicate care, the technology projects the important information displayed by the instrument (such as speed) on the front windshield during the driving process, so that the driver can see the information in the instrument without looking down, not only can help the novice who is inexperienced in judging the speed to control his speed, and avoid violating the rules due to speeding in many speed limit sections, but more importantly, it can enable the driver to read instantaneously under the condition that the large field of view does not shift. Always keep your head clear and observe at your best.

The head-up digital display can map important information on the holographic half-mirror on the windshield glass, so that the driver can see the important information clearly without having to look down.

The car head-up display is a display system originally used in military fighter jets, and now it has been applied in automobiles. HUD (HUD is the abbreviation of HeadsUpDisplay, Chinese means digital display of the head of the car), which uses the principle of optical reflection, can display conventional vehicle information on the windshield, can let the driver's attention focus on the road ahead, to achieve active driving safety.

There are two main types of head-up displays: the suspended HUD is fixed to the sun visor above the driver, so that the HUD information is projected on the upper area of the windshield. The instrument cluster HUD is fixed to the center console in front of the driver, and this arrangement determines that the HUD information will be projected in the area in front of the windshield.

The head-up display shows the content:

The head-up display system of most models can display vehicle speed, engine speed, remaining fuel level, navigation information, etc. There are many cars that have a head-up display system, which is actually a projection of the Takazao Sakura on the front windshield. The head-up display system can display less information, if the display of more information, the area of the shadow is relatively large, which may affect the driver's driving vision.
