The above diagram is a structure of a smart LCD dimming film. Singyes Solar utilizes high-technology to prepare ITO layer on PET masks, creating a soft and transparent conductive ITO film. In between the two layers of ITO film, there is a layer of PDLC to create a dimming film.
The above diagram explains the operation of Smart LCD Dimming Film. When the Smart LCD Dimming Film is turned on, the PDLC particles line up orderly under the impact of the electric field. The refractive index of materials would be similar, which drastically reduces light from scattering, and the Smart LCD Dimming Film would be clear. When the Smart LCD Dimming Film is turned off, PDLC particles scatter, refractive index of materials becomes imbalanced, the dimming film would create intense light scattering, which would present as milk white, tea, or black colored film. Hence the adjustment of the Smart LCD Dimming Film’s supply voltage enables the film’s gradual change of light.
Singyes Solar’s Smart LCD Dimming Glass products’ functionality are exceptional, have excellent optimal performance and solid practical stability. The detailed figures are as shown below:1.Performance Quality
LCD dimming film’s appearance must be color, haze and transparency balanced; the two layers of ITO conducive films must be held together without any signs of peeling; the surface must not have any folds, black spots, or wave patterns; no obvious debris, and the amount of acceptable unremovable adhesives, foreign bodies, empty spots, scratches, etc. are as listed below

Self-adhesive smart LCD dimming film is Singyes Solar’s unique product developed from the foundation of dimming films. Singyes Solar’s smart LCD dimming film’s surface has been processed with hardening treatment, where its hardness reaches 3H, and can avoid PET mask’s scratches and can be stuck on to the surface of glass, providing normal glass the effect of a dimming glass.
Directly paste on the surface of normal glass can enable the function of a smart LCD dimming glass, suitable for reconstruction projects, without having to change the entire glass.
