AUTOMOTIVE GLASS WITH DIRECTIONALLY VARYING TRANSPARENCY (OPTIONS) Russian patent published in 2021 - IPC B60J3/04 G02F1/153 

FIELD: electrochromic automotive glass embodiments.

SUBSTANCE: inventions group relates to embodiments of electrochromic automotive glass. Automotive glass with variable transparency contains two superimposed glass sheets with electrically conductive layers, between which an electrochromic working substance is placed. Busbars for connecting the power supply are fixed to the electrically conductive layers. According to the first option, the tires are made in different sections with different total values of electrical resistance per unit length of the tires. According to the second option, at least one of the buses has at least two separate non-short-circuited sections connected to the power supply in series through different electrical resistances.

EFFECT: arbitrary constructively specified movement of the front of dimming is provided during the transition process from the transparent state of the car glass to the darkened one.
