Attention Xiaomi SU7 owners: Solution to blurry HUD display when wearing sunglasses

News on April 30th: Recently, some owners of Xiaomi SU7 said that when wearing sunglasses, the display effect of the HUD (Head-Up Display) in the car became blurry.

In this case, Xiaomi Motors gave an official explanation. They pointed out that this is a relatively common physical phenomenon and that most HUD systems may suffer from this type of problem. The working principle of HUD is to generate polarized light through TFT liquid crystal display technology, which is then refracted to the vehicle's front windshield and ultimately reflected into the driver's eyes. However, since polarized sunglasses are originally designed to filter this polarized light to reduce the interference of glare and reflected light on the human eye, the image display effect of the HUD will be greatly reduced when wearing polarized sunglasses.

To solve this problem, Xiaomi Auto recommends that car owners who often wear sunglasses and rely heavily on HUD information can consider using non-polarized sunglasses. This can improve the display clarity of the HUD to a certain extent.

In the market, there are three main technical types of sunglasses: first, tinted lenses, which are the most widely used and relatively affordable sunglasses with various lens colors, such as gray, green, brown, etc.; second, photochromic lenses , it can automatically adjust the lens color according to the ambient light, which is very suitable for indoor and outdoor scenes. Finally, there are polarized lenses, which can effectively reduce the reflected light from the water surface or other flat surfaces, especially suitable for drivers or water sports enthusiasts.
