Abstract

The invention relates to a light switching module which comprises a polarized light assembly, a phase difference assembly and a displacement mechanism. The polarized light assembly is provided with a first patterning phase difference layer with a first optical axis changeable in direction. The phase difference assembly is provided with a second optical axis changeable in direction and a light scattering micro-structure. The displacement mechanism is connected with at least one of the polarized light assembly and the phase difference assembly which are arranged in an adjacent mode so as to adjust and control the relative position of the polarized light assembly and the phase difference assembly to change the haze of the light switching module. The light switching module solves the technical problems that an existing light switching module is not even in liquid crystal scattering and needs extra energy consumption.

Description

technical field [0001] The present invention relates to a light switching module, and in particular to a light switching module designed by using the principle of light refraction, which can switch the passing light into a penetrating transparent state or a scattered fog state. Background technique [0002] With the development of smart glass and windows, the application of various light adjustment devices or light switching devices has increased. The technical principle of traditional electronically controlled liquid crystal smart windows is to sandwich polymer dispersed liquid crystals between two pieces of glass, and then use an external electric field to control the liquid crystals, so that the alignment of the liquid crystals is ordered or disordered, and the light penetration is modulated. status. The so-called polymer-dispersed liquid crystals mean that liquid crystal droplets are uniformly dispersed in the polymer substrate, and continuous power supply is required t...
