PDLC, namely
Polymer Dispersed Liquid Crystal. In the absence of an electric
field, liquid crystal molecules are distributed irregularly,
enabling the glass to transmit light while remaining opaque. When an
electric field is applied, liquid crystal molecules arrange in an
orderly manner, allowing light to pass through freely and presenting
a transparent
state.
Based on
reversible electrochemical reactions, the glass interlayer
consists of an electrochromic layer, electrolyte and ion
storage layer. When electrified, lithium ions perform
embedding and de-embedding movements, causing continuous
changes in the light absorption capacity of materials and
realizing a color transition from transparent to
dark.
The
light transmittance is adjusted by controlling the
deflection of dye-doped liquid crystal through
voltage regulation.
