Title (EN) VOLTAGE CONTROL CIRCUIT AND DISPLAY DEVICE
(FR) CIRCUIT DE COMMANDE DE TENSION ET DISPOSITIF D'AFFICHAGE

Abstract:
(EN) A voltage control circuit (5, 5A) having three or more power supplies (51-53, 51-5n) and a selector switch (41, 41A) that selects one of the three or more power supplies (51-53, 51-5n) and connects the selected power supply to the gate signal line (GL) of a liquid crystal panel (10). In the voltage control circuit (5, 5A), the selector switch (41, 41A) sequentially switches the connection of the one of the three or more power supplies (51-53, 51-5n) and the gate signal line (GL) in a prescribed period (1H), whereby the voltage supplied to the gate signal line (GL) is controlled.
(FR) L'invention concerne un circuit de commande de tension (5, 5A) ayant au moins trois alimentations électriques (51-53, 51-5n) et un commutateur de sélection (41, 41A) qui sélectionne l'une desdites trois alimentations électriques (51-53, 51-5n) et connecte l'alimentation électrique sélectionnée à la ligne de signal de grille (GL) d'un panneau à cristaux liquides (10). Dans le circuit de commande de tension (5, 5A), le commutateur de sélection (41, 41A) commute de manière séquentielle la connexion de l'une des trois alimentations électriques (51-53, 51-5n) et de la ligne de signal de grille (GL) dans une période prédéterminée (1H), ce qui commande ainsi la tension fournie à la ligne de signal de grille (GL).
(JA) 3個以上の電源(51~53,51~5n)と、3個以上の電源(51~53,51~5n)のいずれか一つを選択して液晶パネル(10)のゲート信号線(GL)と接続する選択スイッチ(41,41A)とを有する電圧制御回路(5,5A)である。電圧制御回路(5,5A)において、選択スイッチ(41,41A)は、所定周期(1H)で、3個以上の電源(51~53,51~5n)のいずれか一つとゲート信号線(GL)との接続を順次切り換えることによって、ゲート信号線(GL)に供給される電圧を制御する。
