AI Technical Summary
The existing film electrochromic equipment lacks an effective inspection mechanism, which makes it difficult to detect whether the film is discolored normally during use, especially in high-demand places.
A thin film electrochromic device with a safety inspection mechanism was designed. Through the photoresistor sensor and light source module, the light source emitted by the micro LED light source is used for inspection. The photoresistor sensor detects the light intensity to achieve closed-loop control, and combines the re-checking photosensitive sensor to self-check the light source condition to ensure the stability of the equipment.
The closed-loop control of the color-distorted film body is realized, which avoids the film's undistorted film that cannot be detected in time due to equipment failure, improves the stability and safety of the equipment, and reduces light leakage.

The working condition of the micro LED light source is re-inspected by the re-inspection photosensitive sensor to further improve the stability effect.
[0015] By setting up structures such as light-shielding inspection convex convexities, it is possible to avoid or reduce the transmission of light emitted by the micro LED light source to other areas of the film, thereby reducing the intensity of light leakage. BRIEF DESCRIPTION OF THE DRAWINGS
