SECTORIZED ADAPTIVE SCREEN AND DRIVER ASSISTANCE SYSTEM COMPRISING SUCH AN ADAPTIVE SCREEN

An adaptive screen including at least one liquid crystal shutter. At least one of the shutters includes at least two active zones which are addressed by a control signal which permits the switchover of the at least one corresponding shutter between a passing configuration, in which a transmittance i...

More Information
Summary:An adaptive screen including at least one liquid crystal shutter. At least one of the shutters includes at least two active zones which are addressed by a control signal which permits the switchover of the at least one corresponding shutter between a passing configuration, in which a transmittance is equal to a maximum value, and a blocking configuration, in which the transmittance is equal to a minimum value. A "principal" active zone covers a surface area of the adaptive screen which is equal to or lower than 60% of the surface area of the adaptive screen, in order to reduce the response time of the principal active zone.
