Liquid crystal dimming film and liquid crystal dimming laminated glass

Abstract

The invention relates to the technical field of liquid crystal dimming, in particular to a liquid crystal dimming film which comprises a first transparent substrate, a second transparent substrate anda polymer dispersion liquid crystal layer clamped between the first transparent substrate and the second transparent substrate. The liquid crystal dimming film is characterized in that the face, backing onto the polymer dispersion liquid crystal layer, of the first transparent substrate is provided with a first transparent conductive layer, the face, backing onto the polymer dispersion liquid crystal layer, of the second transparent substrate is provided with a second transparent conductive layer, a first electrode is arranged at the first edge of the first transparent conductive layer, a second electrode is arranged at the second edge of the second transparent conductive layer, and the first electrode and the second electrode are used for being electrically connected to the two ends of afirst power source. The liquid crystal dimming film has the advantages that the electrodes of the structure are convenient to install, and on the basis of the heating function, the problem that the dimming film cannot be in use under the cold condition is solved.

Description

Technical field: [0001] The invention relates to the technical field of liquid crystal dimming, in particular to a liquid crystal dimming film and a liquid crystal dimming laminated glass, especially suitable for laminated vehicle window glass. Background technique: [0002] The liquid crystal dimming film is composed of two transparent conductive films and a polymer dispersed liquid crystal layer (PDLC) sandwiched between them. When the power is turned off and there is no electric field, the liquid crystal molecules in between are arranged in disorder, making it impossible for light to pass through. Through the film, the liquid crystal dimming film is in an opaque state; when an alternating current is applied to the conductive layer to apply a voltage, the liquid crystal molecules in between are arranged in an orderly manner, allowing light to pass through the film, and the liquid crystal dimming film changes from opaque to transparent state. Through the action of an appli...

AI Technical Summary

Problems solved by technology

The manufacturing process of the above-mentioned electrodes is relatively complicated and time-consuming, and it is easy to cause the failure of the liquid crystal dimming film due to improper cutting

In addition, the traditional liquid crystal dimming film does not have the function of heating, usually in a low temperature environment (less than -20 ℃), it will cause the failure of the dimming function film, lose the dimming effect, and need to warm up the car before it can be used normally
