Title (EN) DISPLAY DEVICE AND CONTROL METHOD FOR DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ DE COMMANDE POUR DISPOSITIF D'AFFICHAGE
(JA) 表示装置および表示装置の制御方法
Abstract:
(EN) Provided are a display device and a control method for a display device, whereby it is possible to adjust the projection timing and a timing for the scattering state of the screen safely at low cost. The display device (1) generates a common drive voltage output (Vcom), a selection drive voltage output (Vdrv1), and a projector control signal output (Spjo) on the basis of a start-up signal (Sup), a projector control signal (Spj), and a drive control signal (Sdrv), which are sequentially generated and are identical to, but delayed from, a common control signal (Scom) which includes a pulse signal for every two consecutive frame periods (T), said pulse signal having a width equal to the length of the frame periods (T).
(FR) L'invention concerne un dispositif d'affichage et un procédé de commande pour un dispositif d'affichage, au moyen desquels il est possible de régler la base de temps de projection et une base de temps pour l'état de dispersion de l'écran en toute sécurité et avec un faible coût. Le dispositif (1) d'affichage génère une sortie commune de tension d'excitation (Vcom), une sortie de tension d'excitation de sélection (Vdrv1) et une sortie de signal de commande de projecteur (Spjo) sur la base d'un signal de démarrage (Sup), d'un signal de commande de projecteur (Spj), et d'un signal de commande d'excitation (Sdrv), qui sont générés séquentiellement et sont identiques à un signal commun de commande (Scom) mais retardés par rapport à celui-ci, le signal commun de commande comprenant un signal pulsé pour chaque paire de périodes (T) de trame consécutives, ledit signal pulsé présentant une largeur égale à la longueur des périodes (T) de trame.
(JA)  安全かつ低コストに投影タイミングやスクリーンの散乱状態タイミングを調整することができる表示装置および表示装置の制御方法を提供する。 表示装置(1)は、1フレーム期間Tと同じ幅のパルス信号が期間Tの2回に1回出力される共通制御信号Scomを順次遅延させた立ち上げ信号Sup、プロジェクタ制御信号Spj、駆動制御信号Sdrvに基づいて、共通駆動電圧出力Vcom、選択駆動電圧出力Vdrv1やプロジェクタ制御信号出力Spjoを生成する。
