Title (EN) DISPLAY CONTROL DEVICE AND DISPLAY DEVICE
(FR) DISPOSITIF DE COMMANDE D'AFFICHAGE ET DISPOSITIF D'AFFICHAGE
(JA) 表示制御装置及び表示装置
Abstract:
(EN) An objective of the present invention is, in a display device which is visually recognized by a plurality of users, to improve visual recognition for a user who carries out a task such as an input, without impairing the visual recognition of the screen overall. A display control device (1) lights a backlight (30) to reach a first luminosity of a predetermined first display condition in a display region of a display panel (20). When a contact location is detected, the display control device (1) identifies a control region for which the contact location in the display region is a reference. Then, the display control device (1) lights the backlight (30) with respect to the control region, using, in place of the first display condition, a second luminosity of a second display condition whereby a sense of glare is reduced lower than the first display condition, and, with respect to another region which is not the control region, lights the backlight (30) using the first luminosity of the first display condition.
(FR) La présente invention a pour objet, dans un dispositif d'affichage qui est reconnu visuellement par une pluralité d'utilisateurs, d'améliorer la reconnaissance visuelle pour un utilisateur qui exécute une tâche, telle qu'une entrée, sans compromettre la reconnaissance visuelle sur toute la surface de l'écran. Un dispositif de commande d'affichage (1) allume un rétroéclairage (30) pour atteindre, dans une région d'affichage d'un panneau d'affichage (20), une première luminosité d'une première condition d'affichage prédéterminée. Lorsqu'une position de contact est détectée, le dispositif de commande d'affichage (1) identifie une région de commande pour laquelle la position du contact dans la région d'affichage est une référence. Ensuite, le dispositif de commande d'affichage (1) allume le rétroéclairage (30) pour la région de commande, en utilisant, à la place de la première condition d'affichage, une seconde luminosité d'une seconde condition d'affichage grâce à laquelle une sensation de brillance est réduite à une valeur inférieure à celle de la première condition d'affichage, et, pour une autre région qui n'est pas la région de commande, il allume le rétroéclairage (30) à l'aide de la première luminosité de la première condition d'affichage.
(JA)  複数のユーザによって視認される表示装置において、画面全体の視認性を損なうことなく、入力などの作業を行うユーザの視認性を向上させる。表示制御装置1は、表示パネル20の表示領域について予め定められた第1表示条件の第1輝度となるようにバックライト30を点灯させる。表示制御装置1は、表示領域において接触位置が検出されたときに接触位置を基準とする制御領域を特定する。そして、制御領域に対しては、第1表示条件に替えて、第1表示条件より眩輝感が低減される第2表示条件の第2輝度を用いてバックライト30を点灯させ、制御領域ではない他の領域に対しては、第1表示条件の第1輝度を用いてバックライト30を点灯させる。
