Pdlc glass

Introduction: When it is done in a proper way, a piece of glass can adjust the light transmission rate passing through it by changing its transparency or colour. This process is called chromogenic. There are several chromogenics. They are electrochromic, photochromic, thermochromic and gasochromic etc. The most popular is electrochromic. There are two types of electrochromic, PDLC (polymer dispersed liquid crystal) and SPD (suspension particle device). And PDLC is most frequently used. PDLC glass is a light control glass. It can regulate and adjust the light intensity or light transmission passing through the glass. Sometimes, it is known as intelligent glass, magic glass, privacy glass, smart glass or switchable glass. Polymer dispersed liquid crystal film is a light changing liquid crystal film. It is base on the especial performance of liquid crystal material ¡ï¿½plight valve¡ï¿½+. Crystal tiny drop in this film under external electric field rank, distribute in order, when incident light completely permeate, film display clear and colorless state; when external electric field disappear, crystal tiny drop in this film rank order is disturbed, which is made incident light scattering to create ¡ï¿½psandblasted glass¡ï¿½+ effect. Also let positive and negative type of PDLC crystal dye bond make full color light valve film, through change voltage size and frequency to show kinds of color. Regulating light crystal film firstly applies in NASA manned spacecraft glass new material project and obtain success. This material through decade developing after invented, more and more applies in civil product market, because of productive procedure perfecting step-by-step and cost continuously reducing. Regulating light glass is one of the intelligence type of top grade function glass, it adjusts sunlight change from beat and dispersion through voltage on and off, it made glass transparence and protective intimity double requirement come true, even if it is not transparence, light transmitting is also good, ray is enough in room, that is all curtain can not come true, furthermore, it acts as insulation and reflection to infrared, to make inside of room warm in winter and cool in summer, moreover it is environmental protection and energy saving products. This products adopt laminated glass process, are made of regulating light film compound in two piece of glass, it makes use of liquid crystal optic anisotropy to come true regulating light film photo-electricity performance.
