3 Terms and Definitions
The definitions of GB 11614-2009 and JC/T 2129-2012 and the following terms and definitions apply to this document.
3.1
Electro liquid crystal light modulation film polymerdispersedliquidcrystal; PDLC
It is composed of two layers of flexible transparent conductive film and one layer of polymer dispersed liquid crystal material. Through the control of the external electric field, it can be transparent and impermeable.
A fast-changing film that adheres to the glass surface between the two states.
3.2
Breakdown point puncture
Under the action of an electric field, the phenomenon of localized burning of the dimmer film is caused by the discharge between the electrodes.
3.3
Bright edge transparentedgearea
Due to the absence or failure of the dimmer film, the edges of the product that can still see through under power-off conditions.
