Introduction to HUD display
A head-up display is abbreviated as HUD, also known as a head-up display system, which refers to a driver-centric, blind operation, multi-function instrument panel.
Its function is to project important driving information such as speed and navigation on the windshield glass in front of the driver so that the driver can see important driving information such as speed and navigation without lowering his head or turning his head.
aim of design
The driver-centric design is to make it more convenient for the driver to watch the on-board screen and operate the knob while driving; the blind operation is to prevent the driver from taking the line of sight as far as possible from the front; In order to see the navigation as little as possible to divert the driver's attention. In short, the common purpose of these terms is to let the driver not always look left and right when driving, but stare at the road conditions ahead.
Product function
HUD can project the current speed, navigation, and other information on the photoelectric display device on the windshield glass to form an image in front of the glass. Drivers can see navigation and speed information without turning their heads or bowing their heads.

The main basis for the distinction between suspended HUD and instrument desktop HUD is the fixed form.
The suspended HUD is fixed on the sun visor above the driver of the car. This arrangement causes the HUD information to be projected on the upper area of the windshield. The instrument desk HUD is fixed on the center console in front of the driver. This arrangement determines that the HUD information will be projected on the front area of the windshield.
The two types of HUD products have their own advantages and disadvantages:
1) The advantage of suspended HUD is that the product has high adaptability and relatively simple installation.
One of the shortcomings is that the function of the sun visor is occupied; the second one is that it is relatively unstable when fixed on the sun visor, which makes the projection information display unstable; the third one is that the projection information is located in the upper area of the windshield, which is difficult to achieve The driver looks up.
2) The advantage of the instrument desktop HUD is that it is relatively stable and can realize the driver's head-up view.
However, the shortcomings are also obvious. The heat of the DLP optical machine is more obvious. On the center console, especially in summer, the heat dissipation of HUD products becomes a problem, and solving the problem requires a certain cost. In addition, instrument desk HUD products, due to the large difference in the shape of the center console of different models, are less adaptable than the suspension type.
