Windshield head-up display
Head Up Display (HUD) is no longer the patent of fighter planes. HUD was once used as a high-tech configuration of luxury cars, but now HUD has gradually become popular. For example, the following are HUDs from Mercedes-Benz, BMW, and Audi, which project a wealth of colorful digital information onto the windshield.
1. Advantages of HUD
(1) The HUD information display is positioned higher than the traditional instrument cluster. That is to say, when the driver wants to check the vehicle information, he only needs to lower his head by 5-10 ° through HUD; While when looking at the instrument combination, he needs to lower his head by 20-25 °.
(2) when the driver checks the driving information from the instrument combination, his eyes are transferred from the road to the instrument combination and then to the road. Due to the high brightness of the road, the brightness of the instrument combination (inside the car) is low, the eyes will go through the process from bright to dark and then to bright, and the pupils of the eyes will be adjusted; At the same time, the gathering point of the eyes will be from far to near and then to far. When the driver views information on the HUD, their eyes don’t have to strain as much.
2; Windshield
What’s so special about the windshield? The left figure above is a schematic diagram of the interlayer structure of the ordinary windshield. If the HUD image is projected onto the ordinary windshield, it is easy to form an image double image, and the projection effect is poor.
Meanwhile, the PVB interlayer within the windshield’s laminated glass is wedge-shaped, meaning the glass is thicker at the top and thinner at the bottom, which prevents image doubling.
It can also be seen from here that in order to reduce the cost of glass, most of the HUD systems on Class A and Class B cars will be equipped with another piece of reflective glass. Meanwhile, on most luxury brands, where cost constraints are less stringent, they tend to use a head-up display projected onto the windshield.
