However, the people who are inside the coated glass at the same time have a great influence on the visibility outside the vehicle, and once the coated glass is structured, its optical performance will not be reversibly adjusted according to environmental changes or personal preferences, which is difficult to meet The needs of the public to change the light and dark environment in the car at any time
[0004] Similarly, on the premise that the coated glass used in existing windows can reflect light of a certain wavelength in the visible light after molding, once the coated glass is formed, light and shade adjustment cannot be realized.
[0005] At the same time, most of the reflective materials used in coated glass are based on ion crystals doped with metals and metal oxides. The reflective materials that make up this kind of glass are easy to interfere with navigation and communication systems. This shortcoming is not conducive to the popularization and widespread use of coated glass in the world. Applied

Embodiment Construction
[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0030] Such as figure 1 The shown electro-responsive smart glass includes two glass substrates 1 (an upper glass substrate and a lower glass substrate) and liquid crystal dye molecules 7 . An adjustment area 2 is formed between the upper glass substrate and the lower glass substrate.
[0031] Two glass substrates 1 are arranged opposite each other, and each glass substrate 1 is composed of glass and an ITO electrode 5 coated on one surface of the glass. The size of the ITO electrodes 5 is roughly the same as that of the glass. These two ITO electrodes 5 are arranged opposite to each other and are respectively connected to the two poles of the power supply assembly 3. When the switch 3 is closed, the two ITO electrodes 5 are energized, and an electric field is formed between the two glass substrates 1. Th...

Abstract
The invention relates to a smart glass based on an electric response liquid crystal material and a light adjustment method thereof, comprising: two opposite glass substrates, the two glass substrates are respectively electrically connected to two poles of a power supply component; Carrier liquid crystal: dye molecules mixed in the carrier liquid crystal, the dye molecules form a disordered arrangement parallel to the glass substrate under the action of the carrier liquid crystal. The invention mixes the dye molecules with the carrier liquid crystal, fills the mixture between two glass substrates that can be connected to the voltage, and controls the steering of the carrier liquid crystal through the driving voltage to drive the deflection of the dye molecules to regulate the blocking and blocking of visible light. Through, so as to achieve the purpose of smart glass light and shade adjustment. The invention can be applied to the field of construction and household life.
Description
technical field [0001] The invention relates to the field of building and household life, in particular to an electric response smart glass. Background technique [0002] In order to achieve the purpose of sunlight transmission and reflection, glass windows are generally coated so that light of a certain wavelength in the light can be reflected or transmitted by the glass windows. According to different reflective and light-transmitting requirements, films of different materials can be used. [0003] For example, the existing window glass has a coating layer on the surface of the glass, and the coating layer has a high blocking effect on visible light, so it has a better concealment effect on the interior of the car. However, people who are inside the coated glass at the same time have a great influence on the visibility outside the vehicle, and once the coated glass is structured, its optical performance will not be reversibly adjusted according to environmental changes or...
