CA 2463697

The quantity of light from a backlight is monitored by a first photodetector, and the environment on the part of a user is monitored by a second photodetector disposed in the rear of a liquid crystal panel, not on the front thereof. It is possible to exclude the influence of external light from the user side on the first photodetector which detects the quantity of light from the backlight.

L'intensité lumineuse d'un organe de rétroéclairage de dispositif à cristaux liquides est contrôlé par un premier photodétecteur, et l'environnement côté utilisateur est contrôlé par un second photodétecteur disposé à l'arrière du dispositif et non à l'avant. Le problème de l'influence de la lumière pertubatrice sur le premier photodétecteur est résolu du côté utilisateur.
