Abstract

The invention discloses an intelligent light adjusting membrane used for a window display cabinet. The intelligent light adjusting membrane is transparent when electrified and can display an exhibit in a window; when the intelligent light adjusting membrane is not electrified and a projection in the window is started, a projection image can be displayed on the light adjusting membrane. The invention further discloses a preparing method of the intelligent light adjusting membrane. Compared with the prior art, the intelligent light adjusting membrane used for the window display cabinet has the advantages of being low in driving voltage, high in electrifying light-transmitting rate, good in ultraviolet obstructing effect and the like.

Description

technical field [0001] The invention relates to a window display cabinet, in particular to an intelligent dimming film used for the window display cabinet. Background technique [0002] Dimming film (PDLC Film) is an electronic light control product, which refers to the solidification of polymer dispersed liquid crystal between two transparent conductive films. In the absence of an electric field, the dimming film is in an opaque state. When AC power is applied, it is in a transparent state. Generally used for glass partitions, such as hotel partitions, office partitions, bathroom partitions, bank, ticket office window partitions, etc., beautiful and can protect privacy, with multiple functions such as waterproof, heat insulation, dimming, etc., also used in villa windows Glass, car window glass, wine cabinet, bookcase, vending cabinet and other door glass can control the light and privacy; it can also replace the projection screen, and has multiple functions such as projec...
