Automotive HUD (Head-Up Display) Optical Performance Test Solution

The Head-Up Display (HUD) has become a critical interface in today’s intelligent cockpit systems, enhancing driving safety and experience by projecting essential information directly onto the windshield.

However, during the R&D and mass production stages, both OEMs and Tier 1 suppliers often face major challenges in HUD optical performance testing:

· Unstable virtual image with ghosting, distortion, and image shift

· Inconsistent brightness, chromaticity, and uniformity across displays

· Virtual image misalignment due to glass curvature or installation deviation

· Lack of unified optical testing standards and automated measurement tools

· Inconsistencies between lab test results and in-vehicle performance

With the rapid adoption of AR-HUDs and full-glass HUD systems, reliable optical quality testing has become essential for ensuring visual accuracy, safety compliance, and production consistency.

System Components

· Solar Simulation Module：Simulates sunlight reflection and stray light conditions, supporting sunrise, noon, and sunset lighting scenarios.

· Windshield Angle Adjustment Fixture：Reproduces various windshield inclination angles for accurate on-vehicle optical path simulation.

· 6-Axis Motion Platform：Enables automated testing of virtual image position, focal distance, and field of view (FOV) under multiple angles.

· Optical Alignment & Measurement Module：Supports integration with multiple luminance and color meters for uniformity, distortion, brightness, and chromaticity analysis.

· Automated Test Management Platform：Allows creation and execution of test cases, automated result processing, and report generation for traceable, quantifiable optical data.

Through standardized vehicle-level simulation, results are repeatable, traceable, and quantifiable, enabling precise analysis of each pixel’s optical performance and resolving optical uniformity issues at their source.

Key Test Dimensions：
