AI Technical Summary

Technical Problem

Existing head-up display technologies in vehicles face challenges such as high installation space requirements, inability to produce large-area images, and issues with luminance, contrast, and visibility in strong ambient light, along with potential image leakage and interference from external light sources.

Method used

A micro-LED display device comprising layers of lenticular lenses, circular polarizer, louvered film, and anti-reflective cover glass, optimized to enhance luminance, reduce reflections, and secure image visibility within the vehicle while blocking external views.

Benefits of technology

The solution significantly enhances luminance by 250-400%, improves contrast, reduces external visibility, and minimizes distracting reflections, ensuring clear image display under various lighting conditions.
