There is a kind of glass that becomes opaque when it is electrified.

Liquid crystal glass, also called electrically controlled liquid crystal glass, electrically controlled dimming glass and dimming glass, is named after liquid crystal film, the core material of dimming glass. So,

Liquid crystal glass (Polyvision privacy glass) (1 piece) is used to be called LC glass abroad (usually called Polyvision glass, switchable glass, privacy glass). Liquid crystal glass is a high-tech photoelectric glass product with laminated liquid crystal films at high temperature and high pressure. Users can control the arrangement of liquid crystal molecules by whether the current is energized or not, so as to achieve the ultimate goal of controlling the transparent and opaque state of glass. Liquid crystal film in the middle layer is used as the functional material of dimming glass. The application principle is: liquid crystal molecules are arranged in a straight line when power is applied, and the liquid crystal glass is transparent at this time; When the power is cut off, the liquid crystal molecules are scattered, and the liquid crystal film is transparent but opaque. Scientists use this characteristic to develop liquid crystal glass products. The patent was first obtained by Kent State University in the United States, and it was the first in the world to authorize Polytronix, Inc. in Texas, USA to mass-produce liquid crystal film products (the first brand of Polyvision privacy glass).

Edit the application of liquid crystal glass in this paragraph.

Dimming device of related electronic equipment: light control element. Electronic cat's eye of safety door: replacing traditional electronic cat's eye components of safety door. Hotel or family bathroom partition glass: suitable for ordinary bathroom doors and windows, beautiful, atmospheric, and privacy protection. Bank: Combined with bank security system, it is applied to the design of bank counter glass and access passage to improve security performance. Showcase: Dimming glass can isolate more than 99% ultraviolet rays, prevent the aging of exhibits caused by light and protect the safety of exhibits. Hospital intensive care unit: protect the privacy of patients, so that patients are not disturbed, and the indoor situation can be seen at a glance after power-on. Shopping mall decoration: dynamic window display makes goods more attractive. Vehicle application: it can be used as a side window, rear window or skylight of a vehicle; It can be used in various fields, such as partition windows of luxury cars or SMRT, privacy protection windows of high-speed rail or train cab. More application fields, looking forward to your design and excavation.

Edit the difference between liquid crystal glass and electrochromic glass in this paragraph.

1) liquid crystal glass is generally opaque, and it can only be changed from opaque to transparent at a certain voltage; The electrochromic glass itself may be transparent. 2) Liquid crystal glass needs constant voltage application to remain transparent, which is an energy-consuming product, but its energy consumption is relatively low; Electrochromic glass has bistable characteristics. By adjusting the light transmittance of the glass, the state of the glass can be maintained for a period of time after the voltage is removed. 3) Ordinary liquid crystal glass can only be adjusted between transparent and opaque states; Electrochromic glass can usually be adjusted to different light transmittance levels under different voltages. 4) The main principle of liquid crystal glass is to achieve the purpose of dimming according to the orientation of liquid crystal molecules under the action of voltage; The main principle of electrochromic glass is that electrochromic materials undergo redox reaction under the action of voltage, and then the color and transparency change to achieve the purpose of dimming.
