[0002] Currently, automotive head-up display technology projects driving-related information onto the car's front windshield in the form of an image. When testing whether the head-up display glass image is qualified, the image effect at the windshield is manually observed to determine whether it meets the requirements. However, when observed with the human eye, the subjective factor is relatively large, and the test results of different people for the same product may also vary. Moreover, due to the lack of more professional testing equipment, the relevant test parameters are manually adjusted, and accurate values cannot be achieved, which affects the test results.

The HUD imaging screen includes a transparent substrate with a curvature forming a concave surface. The inner surface of the concave surface is coated with an optical film. This film strip has both optical transmission and reflection functions, forming a concave mirror with a certain transmittance. At the same time, the convex surface of the concave mirror is coated with an anti-reflection optical film with strong light transmission effect, so that the concave mirror appears more transparent from the front; this device also fails to solve the above-mentioned technical problems.
