Abstract

The invention discloses an electrically-controlled dimming device. The electrically-controlled dimming device comprises an upper transparent base material, a first functional layer, an electrically-controlled adjustable optical refractive index layer, a second functional layer and a lower transparent base material which are sequentially arranged, wherein each of the first functional layer and the second functional layer comprises a conducting layer, and at least one functional layer contains a microstructural layer; the electrically-controlled adjustable optical refractive index layer has the capability of converting the optical refractive index from n1 to n2 under the driving of voltage; the refractive index of the microstructural layer is n, and n is equal to n1 or n2. By controlling a switch of a power supply, the refractive index of the electrically-controlled adjustable optical refractive index layer is changed; by taking advantage of the difference between the refractive indexes of the microstructural layer and the electrically-controlled adjustable optical refractive index layer, when the refractive indexes are the same, a transparent state is presented, and when the refractive indexes are different, a hazy state is presented, so that switching from the transparent state to the hazy state is achieved and thus a dimming purpose is achieved. The electrically-controlled dimming device is simple in structure, easy in industrial production and good in conversion effect, and can arbitrarily adjust the haze according to needs.

Description

technical field [0001] The invention belongs to the technical field of light adjustment, and in particular relates to an electronically controlled light adjustment device. Background technique [0002] Polymer dispersed liquid crystal (polymer dispersed liquid crystal) is to mix low-molecular liquid crystals with prepolymers, and undergo polymerization reaction under certain process conditions to form micron-sized liquid crystal particles uniformly dispersed in a solid polymer matrix. The obtained liquid crystal particles have dielectric anisotropy. Under the condition of an external electric field, the polymer dispersed liquid crystal can realize the transition between transparent and opaque, so that the light transmittance of the film can be adjusted. [0003] Polymer dispersed liquid crystal technology has been widely used in electronically controlled dimming glass, holographic grating and many other technical fields. The product of polymer dispersed liquid crystal has t...
