What is switchable glass?

Switchable glass is also called PDLC glass or switchable privacy glass. As a new type of special privacy glass has been welcomed by more and more people.

Switchable glass is processed by laminated the switchable film between two pieces of glass, using laminated technology, let the switchable film always be sandwiched between the glass without separating.

The switchable film, (also known as smart switchable film or PDLC film). The active component in switchable film (PDLC – Polymer Dispersed Liquid Crystal) consists of liquid crystal microdroplets which are suspended in the polymer. The natural state of the film sees the PDLC molecules arranged in a way that causes light waves to refract through and reflect away from the surface, distorting the state of the glass to present as frosted. When an electrical current is passed through the PDLC layer, the liquid crystal molecules polarise, allowing light to pass through.

How does the switchable privacy glass work?

What do you think if could achieve privacy with just the flick of a switch? The switchable privacy glass turns from clear to opaque in less than 1 second. All it takes is an electrical current to activate the unique smart switchable glass properties.

The dimming principle of switchable glass is: in the natural state, its internal liquid crystal molecules are arranged without rules, the refractive index of the liquid crystal is lower than the refractive index of the polymer outside, the incident light scattering in the polymer, is milky white, that is, opaque. After electrification, the dispersion distribution Liquid droplets in the liquid crystal polymer are rearranged, and the liquid crystal changes from disorder to the directional orderly arrangement, so that the refractive index of the liquid crystal is the same as that of the polymer, and the incident light can completely pass through to form a transparent state.

Switchable glass parameters

Our switchable privacy glass has passed various stringent tests, ensuring the high quality of the product. When power is on, the all-optical pass rate is up to 82%, the fog is less than 3.5% when power is off, the fog is up to 95%, the power consumption is less than 4w/ m², the photoelectric performance is excellent, and reaches the international advanced level.

  5. Soundproofing features: Can partially block noise.
  6. Stable performance and long service life: The number of switches reaches more than 30 million, and it can be used for more than 50,000 hours under the open state, and it can be used normally for 15 years.
  7. Diversified control methods: Manual switch, remote control, trigger control, voice control, mobile APP control, timing control, remote network control, etc., can be customized according to customer needs.


Switchable privacy glass is a tool to create dynamic, expansive, light-filled environments with on-demand opacity.
