"The Hidden Purpose of Car Windscreen Black Dots Revealed"
The black dots, known as dot matrices or frit, on car windscreens have an important role in distributing temperature evenly across the glass, reducing optical distortion and ensuring a smoother and safer journey. They also help preserve the urethane sealant used to bond the glass to the frame and serve as a contact point between the glass and car frame. The dots create an aesthetic pattern that makes the transition between the dark band and transparent glass more subtle. Many drivers were unaware of the purpose of these dots and were amazed to learn about their functionality.
