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.
