Abstract
An intelligent window includes two substrates and a dimming layer. Each substrate is electrically connected to a voltage source. A switchable electric field is formed between the two substrates. The dimming layer is formed by filling a liquid crystal material between the two substrates. The liquid crystal material is formed by mixing a chiral molecule, a dichroic dye, and a salt ion in a nematic liquid crystal. A weight percentage concentration of the chiral molecule in the liquid crystal material is determined according to a limitation formula (I). C is the weight percentage concentration, n is a birefringence index of the liquid crystal material, p is a chiral force of the chiral molecule in micrometer, D is a thickness of the dimming layer in micrometer, mis a constant of multiaxial absorption condition in micrometer, and mis a constant of normally transparent condition.
