Abstract
(EN)
The present invention realizes a liquid crystal display device capable of suppressing power consumption and manufacturing costs. In a television receiver (1), only four LED light sources (4) in the center part among all the LED light sources (4) formed on an LED substrate (5) are in a lighted state in the case that the low power consumption display mode has been selected. A predetermined image is displayed in the lighted area (the area from which light is emitted) and in the overlapping display area of the liquid crystal display panel (2) as viewed from above among the plurality of areas of the light-emitting surface provided to the LED backlight unit (3).

La présente invention réalise un dispositif d'affichage à cristaux liquides capable de supprimer une consommation de puissance et des coûts de fabrication. Dans un récepteur (1) de télévision, seulement quatre sources (4) de lumière LED dans la partie centrale parmi toutes les sources (4) de lumière à Diodes Électroluminescentes formées sur un substrat de Diodes Électroluminescentes (5) sont dans un état éclairé dans le cas où le mode d'affichage à faible consommation d'énergie a été sélectionné. Une image prédéterminée est affichée dans la zone éclairée (la zone à partir de laquelle la lumière est émise), et dans la zone d'affichage se chevauchant du panneau (2) d'affichage à cristaux liquides, tel que vu depuis le dessus, parmi la pluralité des zones de surface d'émission de lumière fournies à l' unité (3) de rétro - éclairage à DEL.
