Abstract
(EN) This display device comprises: an n (where n is an integer of 2 or more) number of liquid crystal displays; light sources that can emit light of a plurality of different colors and that are provided to the respective liquid crystal displays; and a processor that causes the light sources to emit light of different colors so as to vary emission start timings for the respective light sources provided to the liquid crystal displays on the basis of input signals including color information regarding sub display images to be displayed on the respective liquid crystal displays.
(FR) La présente invention concerne un dispositif d'affichage qui comprend : un nombre n (n étant un nombre entier supérieur ou égal à 2) de dispositifs d'affichage à cristaux liquides ; des sources de lumière qui peuvent émettre de la lumière d'une pluralité de couleurs différentes et dont les dispositifs d'affichage à cristaux liquides respectifs sont munis ; et un processeur qui amène les sources de lumière à émettre de la lumière de couleurs différentes de façon à faire varier les moments du début de l'émission pour les sources de lumière respectives dont les dispositifs d'affichage à cristaux liquides sont munis sur la base de signaux d'entrée comprenant des informations de couleur concernant des sous-images d'affichage à afficher sur les dispositifs d'affichage à cristaux liquides respectifs.
(JA) 表示装置は、ｎ（ｎ：２以上の整数）枚の液晶ディスプレイと、液晶ディスプレイごとに設けられた複数の異なる色の光を発光可能な光源と、それぞれの液晶ディスプレイに表示されるサブ表示画像の色情報を含む入力信号に基づいて、液晶ディスプレイごとに設けられた光源のそれぞれの発光開始タイミングが異なるように、光源ごとに異なる色の光を発光させるプロセッサと、を備える。
