SmartGlass (PDLC / Intelligent / Privacy / LC / Switch) Glass & Film




Smart Glass & Film Are Transparent When Electricity Is Applied & Change To Opaque When Electricity Is Cut-Off

PDLC stands for polymer dispersed liquid crystal. Liquid crystals are well known for flat panel displays. Liquid crystal display, LCD is the most popular flat panel displays which are applied in daily use products such as portable computer, cellular phones, calculators, digital clocks and watches, etc. In LCD, electricity is used to change the shape of liquid crystals to allow light to pass through and thus forming colors, images, figures and numbers on the displays.

In polymer dispersed liquid crystal, it is just simply a combined application of polymers and liquid crystals. Liquid crystals respond to an electrical charge. When current flows, each crystal droplet is activated to align parallel permitting light passes through resulting in transparency. When electrical charge is absent, liquid crystals droplets are randomly oriented. Light is heavily scattered. It does not permeate in a straight way and thus, resulting in opaque.


It is also known as smart, intelligent, magic, privacy, electrochromic, light regulate, switchable or also LC liquid crystal film. PDLC controls light intensity passing through. When there is no electric current, liquid crystal droplets are randomly oriented. They do not allow light passing through, instead, they scatter light rays. The film is, therefore, opaque but light rays are dispersed. When electric current flows, liquid crystal droplets aligning parallel allowing light passing through and thus, it becomes transparent. With just simply a flip of switch, it is instantaneously changing between clear and opaque states.

PDLC Glass

In practical applications, PDLC films are always covered and protected by glass or plastic panels. PDLC glass is then formed. It is also known as smart glass or window, intelligent glass or window, magic glass or window, privacy glass or window, electrochromic glass or window, light regulate glass or window, switchable glass or window and also LC liquid crystal glass or window.
