GLAZING PANEL OF VEHICLE WITH POLYMER-DISPERSE LIQUID CRYSTAL FILM, WITH GIVEN DROPLETS DISTRIBUTION ON DIMENSIONS FOR ATTENUATION OF CROWN EFFECT Russian patent published in 2020 - IPC G02F1/17 

FIELD: glass.

SUBSTANCE: invention relates to a glazing panel of a vehicle, the light transmission coefficient of which can be varied by supplying electric voltage. Panel comprises first glass panel (1), one or multiple polymer layers (2), PDLC layer (4) comprising polymer matrix (9), in which liquid crystal droplets (8) are included, where on both sides of the PDLC layer is located along electroconductive layer (3, 5), or the SPD layer containing the polymer matrix, into which suspension droplets are included, in which the light polarizing particles are suspended, wherein on both sides of the SPD layer there is an electroconductive layer, one or a plurality of polymer layers (6) and a second glass panel (7). At that, in the case of PDLC of liquid crystal droplets layer or in case of SPD-layer, suspension droplets have average size more than 2 mcm, preferably at relative standard deviation of more than 30 %. Glazing panel of the vehicle can be switched between a transparent state and a turbidity or opacity state.

EFFECT: in the transparent state in the glazing panel of the vehicle according to the invention, weakened effects of the crown and rainbow are manifested.
