Electric-controlled light-regulating medium

Abstract

The invention discloses an electronic control dimming medium which comprises two substrate layers. A mixed layer is arranged between two substrate layers and is made by mixing smectic phase liquid crystal and additives. A conductive electrode layer is arranged at the sides of two substrate layers towards the mixed layer, and the conductive electrode layer is connected with a circuit drive controlapparatus. Two substrate layers can be made of glass, or two substrate layers can be made of plastic, or one substrate layer is made of the glass, and the other substrate layer is made of the plastic. When an electric signal which is applied to the conductive electrode layer is controlled, smectic phase liquid crystal molecules can be characterized by different arrangement states, and the arrangement states are the same in the electroless case, so as to ensure that the medium can be switched between a vaporific shielding state and a full transparent state and even can be switched among various gradual progress states of different gray scales. The electronic control dimming medium can be widely applied to the fields of building decoration and fitment, privacy control area, automobile electronics, electronic bulletin board, etc.

Description

technical field [0001] The present invention relates to an electronically controlled light-adjusting medium, in particular to an electrically-controlled light-adjusting medium that can be switched between foggy shading and fully transparent states by controlling the electrical signal applied to the conductive electrode layer . Background technique [0002] At present, glass that can achieve dimming effect is mainly realized through four technologies: electrochromism, photochromism, thermochromism and piezochromism. Among them, the dimming glass produced by photochromic, thermochromic and piezochromic technologies is greatly affected by environmental factors, and it is not a self-controlled dimming glass in a complete sense. [0003] The well-known suspendable particle-based switchable glass invented by the Koreans is a switchable glass made using electrochromic technology. This kind of glass adjusts the transmission and scattering of light by controlling the number of sus...
