A newly filed patent (Publication Number: US20240025156A1) describes a head-up display glass designed with specific layers and coatings to enhance reflectivity for P-polarized light. The glass includes an outer and inner glass sheet, an intermediate layer, a transparent conducting coating, and an enhanced reflection coating. The transparent conducting coating and enhanced reflection coating have minimum reflectivity thresholds to ensure optimal performance. Additionally, the transparent conducting coating is equipped with busbars for heat generation and has a specific sheet resistance range. The enhanced reflection coating consists of high and low refractive-index layers stacked in a particular sequence to achieve the desired reflectivity levels.

Furthermore, the patent details a head-up display system incorporating the specialized head-up display glass and a projection unit. The system is designed to generate P-polarized light at specific angles of incidence, ensuring efficient reflection by the enhanced reflection coating to create a clear head-up display image. The system allows for the superimposition of multiple head-up display images with high visibility and projection distances ranging from under 5 meters to 10 meters or more. Overall, the patent outlines a comprehensive approach to improving head-up display technology through innovative glass design and system integration, promising enhanced visibility and performance for users.
