Privacy smart glass

 

The privacy smart glass is a new type of special photoelectric glass product with a sandwich structure that combines a liquid crystal film into the middle of two layers of glass, and is integrated by high temperature and high pressure. The user controls the transparent and opaque state of the glass by controlling whether the current is on or off. The glass itself not only has all the characteristics of safety glass, but also has the privacy protection function to control whether the glass is transparent or not. Due to the characteristics of the liquid crystal film interlayer, the dimming glass can also be used as a projection screen, replacing ordinary curtains, and presenting high-definition pictures on the glass image.

According to the similarities and differences of the control methods and principles, the dimmer glass can switch between the transparent and opaque states of the glass through various methods such as electric control, temperature control, light control, and pressure control. Due to various constraints, most of the dimming glasses that have been mass-produced on the market are electronically controlled dimming glasses.

The principle of electronically controlled dimming glass is relatively easy to understand: when the electronically controlled product is turned off, the liquid crystal molecules in the electronically controlled dimmable glass will be irregularly dispersed, preventing light from entering and making the electrically controlled glass appear opaque .

 

Electric frosted glass film

 

Polymer dispersed liquid crystal, also known as PDLC (polymer dispersed liquid crystal), is a liquid crystal dispersed in micron-sized droplets in an organic solid polymer matrix, because the optical axis of the droplets composed of liquid crystal molecules is in free orientation , Its refractive index does not match the refractive index of the substrate, and when light passes through the substrate, it is strongly scattered by the droplets and presents an opaque milky white state or a semi-transparent state. The application of an electric field can adjust the orientation of the optical axis of the liquid crystal droplets. When the refractive indexes of the two are matched, they will appear transparent. After the electric field is removed, the liquid crystal droplets return to their original astigmatism state, thus displaying.

Switchable privacy glass cost

 

According to the glass structure, the cost of glass can be calculated as: film cost, substrate cost and dimming film cost. Take 5 5 dimming glass as an example: the structure contains 2 layers of 5mm ordinary glass, and the production cost is $20/square. Film 2 The layer cost is 15 US dollars/square meter, and the dimming film cost is roughly 70 US dollars/square meter. The overall production cost is expected to be around 105 US dollars/square meter. The above are mainly flat plates, excluding curved, bent steel and other special types.
