Polymer dispersed liquid crystal

Generally, the liquid mixture of polymer and liquid crystal is placed between two layers of glass or plastic, the two layers of glass or plastic including a layer of transparent conductive material, and then the polymer is cured to form the basic sandwich structure of a smart window. The structure is actually a capacitor.

The electrode from the power source is attached to the transparent electrode. When no voltage is applied, the liquid crystals are randomly arranged in the droplets, causing light to scatter when passing through the smart window assembly. This results in a translucent "milky white" appearance. When a voltage is applied to the electrodes, the electric field formed between the two transparent electrodes on the glass aligns the liquid crystals so that light passes through the droplets with little scattering and forms a transparent state. The degree of transparency can be controlled by the applied voltage. This is possible because at lower voltages, very few liquid crystals are perfectly aligned in the electric field, so only a small part of the light will pass through and most of the light will be scattered. As the voltage increases, fewer liquid crystals remain misaligned, resulting in less light being scattered.

Pdlc film

The film data is flexible, and the common application is to stick on the surface of the object. The structure of the PDLC film is mainly achieved by the transparency and frosting effect of the PDLC smart liquid crystal molecules mentioned above.

The structure of the film layer: ITO+PDLC+ITO conductive material. Due to the high toughness of ITO conductive material, it can protect the inner PDLC molecular layer from the external environment, effectively improving the service life of the material

Application scenario

The film is generally used as a pasting material. Common application scenarios include glass partitions, shower rooms, windows, or doors, which are similar to mobile phone tempered films.
In the pasting process, you need to clean the pasting surface, and avoid using acidic or alkaline cleaners during the cleaning process. After the film is pasted, try to check that the lower edge is well wrapped and the power-on test is enough to work properly
