AI Technical Summary
⚠Technical Problem
Conventional methods for suppressing interference light in head-up displays are either partially effective, complex, costly, or require additional installation space, and they fail to adequately address diffuse and specular reflections, particularly when sunlight is the interference source.
⚗Method used
A planar surface structure with cavities and pegs or webs that absorb and scatter interference light, featuring non-planar boundaries and broadband light-absorbing surfaces, reducing specular and diffuse reflections through a 3D printing process.
🎯Benefits of technology
The solution effectively suppresses interference light, providing a matte and dark appearance even under bright sunlight, minimizing distracting reflections and enhancing visibility in head-up displays.
