What Are the Black Dots on the Windshield?

[VivienneMarie]

The black dots on the windshield are a type of glass with a ceramic-like structure. According to explanations from automotive glass manufacturers, these black edges and dots are actually created using a ceramic sintering technology, resulting in a glass structure resembling ceramics. The functions of these black dots are as follows: 1. Improve glass clarity: The high thermal conductivity of the black dots allows heat to distribute more evenly, making the windshield clearer. 2. Enhance glass durability: The black color absorbs heat, and through these variously sized dots, heat is absorbed, stored, and evenly transferred to the center of the glass, effectively preventing windshield cracking. 3. Protect vision: While minimizing obstruction to the driver's view, the black dots also reduce direct sunlight exposure to the eyes, thereby decreasing the harm of strong light to the eyes and helping to alleviate driving fatigue.
