General Questions

PDLC (Polymer Dispersed Liquid Crystal) film and glass are types of switchable smart glass technology that use a liquid crystal layer to control the transparency of the glass. When power is on it becomes transparent, when power is off it becomes opaque.

PDLC film and glass can also be designed to have multiple states, allowing for variable light control and privacy. For example, by adjusting the voltage applied to the film or glass, it can be set to partial transparency or different levels of opacity.

PDLC (Polymer Dispersed Liquid Crystal) film and glass work by using an electric current to change the alignment of liquid crystal droplets dispersed in a polymer matrix. The droplets are sandwiched between two layers of transparent ITO film materials.

When an electrical current is applied to the PDLC film or glass, the liquid crystal droplets align themselves to form a transparent state, allowing light to pass through. When the electrical current is turned off, the droplets randomly scatter and block light, creating an opaque or frosted appearance.

PDLC technology works by dispersing tiny liquid crystal droplets in a polymer matrix, which is then sandwiched between two layers of transparent ITO film materials, and form the regular PDLC film(We also call it non-adhesive PDLC film or PDLC film for lamination).

When the regular PDLC film combine with a self-adhesive layer, the self-adhesive PDLC film is made. Self-adhesive PDLC film can be stuck on glass surfaces directly, and is ideal for retrofitting existing glass partitions, windows, and doors.

PDLC glass, on the other hand, consists of two or more glass layers with a regular PDLC film layer sandwiched in between. The PDLC film is bonded to the glass layers using a lamination process.

PDLC glass provides privacy, light control, energy savings, and UV protection. It also offers a modern and elegant aesthetic. It can also be used for projection screens and advertising displays.

The cost of PDLC glass varies depending on the size, thickness, and complexity of the installation. It is generally more expensive than conventional glass.The EXW price of our PDLC glass ranges from $110-130 USD per square meter, and PDLC film range from $55-75USD per square meter, depending on the size and quantity of the order. For very large orders, you may be able to negotiate a bulk discount.

Normally needs 7-15 days for PDLC glass production and 3-7 days for PDLC film production. Depends on the required glass/film dimensions and quantities.

PDLC film and glass are safe when installed properly and used according to the manufacturer’s instructions. PDLC glass is shatter-resistant and can be laminated for added safety.

PDLC film and glass are energy efficient because it can reduce energy consumption by blocking out heat and UV radiation from the sun, which can help reduce the need for air conditioning and heating systems
