POLYMER-DISPERSED LIQUID CRYSTAL LIGHT-REGULATION STRUCTURE

摘要

A polymer-dispersed liquid crystal light-regulation structure comprises a liquid crystal light-regulation layer, a first anti-infrared light-permeable conductive layer, a second anti-infrared light-permeable conductive layer, a first light-permeable substrate, and a second light-permeable substrate. The first and second anti-infrared light-permeable conductive layers are respectively disposed on two sides of the liquid crystal light-regulation layer. The first and second light-permeable substrates are respectively disposed on sides of the first and second anti-infrared light-permeable conductive layers, which are far away from the liquid crystal light-regulation layer. The first and second anti-infrared light-permeable conductive layers not only retard infrared light from entering the building and lower the indoor temperature but also function as electric-conduction structures electrically energized to vary the light transmittance of the liquid crystal light-regulation layer, whereby fewer layers are used in the present invention, and whereby is reduced the overall thickness of the present invention.
