A light control film with different light transmittances in on and off states and light control glass

By introducing changes in the concentration of light-controlling active components into the dimming film, the light transmittance of the dimming film changes continuously and gradually in the off or on state, which solves the problem of uniform light transmittance of existing dimming films and meets the functional and aesthetic requirements of transportation vehicles and buildings.

Abstract

The application provides a light-adjusting film and light-adjusting glass with visible light transmittance change effect in off or on state. A light-adjusting film with visible light transmittance changeable in off or on state is obtained by controlling the concentration distribution of active components in a light-adjusting layer. The light-adjusting film can play a comprehensive light-adjusting role in application scenarios requiring transmittance change, and meet the functional, aesthetic and other scene use requirements in the fields of vehicles or buildings.
