AI Technical Summary
Technical Problem
Existing head-up display systems in vehicles face issues with double images due to surface reflection and inferior scratch resistance of reflective layers on windshield glass, particularly when projecting images onto areas with varying incident angles.
Method used
A laminated glass configuration with specific reflective and light-shielding layer arrangements, including regions with controlled P-polarized reflectance and ultraviolet light reflectance, to minimize double images and enhance scratch resistance.
Benefits of technology
The laminated glass design effectively suppresses double images and improves scratch resistance, ensuring clear visibility and durability for head-up display systems.
