AI Technical Summary
Existing dimming film products can only achieve uniform light transmittance and cannot achieve different light transmittance at different locations. Furthermore, they are prone to freezing and condensation in cold and humid environments, making them unable to function properly.
By setting a special combination of conductive lead circuits in the transparent conductive layer, the internal circuit layout of the dimming film is changed, allowing different voltages to be obtained at different locations, thereby achieving adjustable light transmittance. The conductive leads also provide a heating function to eliminate environmental influences.
It achieves a gradual change in light transmittance at different positions of the dimming film and maintains normal operation in cold and humid environments, thus expanding the application scenarios of the product.
