Abstract: A color-changing light-adjusting liquid crystal device and a light-adjusting method may include a main liquid crystal and a dichroic dye, which may be filled between substrates disposed oppositely, in a non-powered state. The main liquid crystal may be subjected to a specific arrangement orientation under an induction of an alignment layer, in a powered state, and the main liquid crystal may be subjected to a reorientation. Dichroic dye molecules may be rotated along with the reorientation of the main liquid crystal so as to scatter incident light in a visible spectrum, convert a light-transmitting state into a light-scattering state at a macro level, and display a color of the dichroic dye in the main liquid crystal, thus implementing light adjustment. The color-changing light-adjusting liquid crystal device does not contain a polymer network, so that a polymerization process is not needed and a polymer aging is avoided.

Abstract: A light-adjusting device and a light-adjusting method thereof are disclosed. A main liquid crystal and salt from which ions are ionized are filled between adjusting areas formed by oppositely arranged substrates, the main liquid crystal is arranged in a specific orientation under an induction of an alignment layer under an unpowered state, the main liquid crystal is re-oriented under an powered state, meanwhile, ions ionized from the salt from which ions are ionized move quickly under an effect of an formed electric field, which disorganizes the specific orientation arrangement of the main liquid crystal, so that the main liquid crystal moves irregularly following a quick movement of the ionized ions, so as to scatter incident light in a visible light band, and further adjust transmission and scattering of visible light, thus realizing light adjustment.
