AI Technical Summary
Technical Problem
The position shift of the diffuser film in a head-up display can cause laser light to be directly emitted into the driver's eyes, posing a safety risk due to the inability to detect and prevent such shifts effectively.
Method used
A detection apparatus comprising a power supply, conductive module, and detection module forms a closed loop with the diffuser film, detecting when the loop opens due to film shift, triggering a control module to turn off the laser light source to prevent direct emission.
Benefits of technology
Prevents laser light from being directly emitted into the driver's eyes by detecting and responding to diffuser film shifts, ensuring safety and normal operation of the head-up display.
