Method for state switching of switchable glass

Abstract

A method for state switching of a switchable glass to resolve the time delay in switching conventional switchable glass from a hazy state to a transparent state. The method includes a transparency stage, an operation stage and a state switching stage. In the transparency stage, no voltage is applied to the switchable glass and the switchable glass is in a transparent state. In the operation stage, an alternating current is applied to the switchable glass, with an amplitude of the alternating current maintained at a first voltage, and the switchable glass is in a scattering state. In the state switching stage, the amplitude of the alternating current is raised to a second voltage after the operation stage, with the second voltage greater than the first voltage, and the switchable glass maintains in the scattering state.
