An image display apparatus comprises a light valve for controlling at least the intensity of light projected along an optical path from a light source through the light valve. The light valve has a plurality of light transmitting elements at least the translucency of each of which may be adjusted periodically such that the translucency of each element is substantially constant except during intervals within which the translucency is being adjusted. A shutter is provided to obstruct the light path through at least one of the fight transmitting elements during intervals within which the translucency of the element is being adjusted.
Cet appareil d'affichage d'images comprend un modulateur de lumière servant à commander au moins l'intensité de la lumière se projetant selon un trajet optique partant d'une source de lumière et traversant le modulateur de lumière. Ce modulateur de lumière comporte une pluralité d'éléments photoémetteurs dont la translucidité peut se régler individuellement périodiquement de façon que la translucidité de chaque élément soit sensiblement constante, sauf pendant des intervalles de temps où la translucidité fait l'objet d'une correction. Un obturateur vient occulter le trajet lumineux traversant l'un au moins des éléments photoémetteurs pendant les intervalles de temps où la translucidité de l'élément fait l'objet d'une correction.
