Title (EN) DISPLAY DEVICE, ELECTRONIC APPARATUS, AND PROJECTION-TYPE DISPLAY DEVICE

Abstract:
(EN) The display device according to an embodiment of the present disclosure is provided with: a first driving unit that sequentially selects pixels in a row unit; and a second driving unit that applies a video signal via a signal line to each pixel in a pixel row selected by the first driving unit and that inverts the polarity of the video signal at predetermined cycles. Before applying a signal voltage, the second driving unit sequentially applies, to the signal line, a first pre-charge signal voltage having a relatively large amplitude and a second pre-charge signal voltage having a relatively small amplitude. Further, the second driving unit controls application of the first pre-charge signal voltage such that the amount of current leakage from the pixels to the signal line, which is caused by application of the first pre-charge signal voltage, in each predetermined horizontal period becomes smaller than those in other periods.
(FR) Un mode de réalisation de la présente invention concerne un dispositif d'affichage pourvu : d'une première unité de commande qui sélectionne successivement des pixels dans une unité de rangée ; et d'une seconde unité de commande qui applique un signal vidéo par le biais d'une ligne de signal à chaque pixel d'une rangée de pixels sélectionnée par la première unité de commande et qui inverse la polarité du signal vidéo selon des cycles prédéfinis. Avant d'appliquer une tension de signal, la seconde unité de commande applique successivement, à la ligne de signal, une première tension de signal de précharge ayant une amplitude relativement grande et une seconde tension de signal de précharge ayant une amplitude relativement petite. En outre, la seconde unité de commande commande l'application de la première tension de signal de précharge de sorte que la quantité de fuite de courant des pixels vers la ligne de signal, qui est provoquée par l'application de la première tension de signal de précharge, lors de chaque période horizontale prédéfinie, devienne inférieure à celle correspondant à d'autres périodes.
(JA) 本開示の一実施の形態にかかる表示装置は、各画素を行単位で順次選択する第1駆動部と、第1駆動部によって選択された画素行の各画素に対して映像信号を、信号線を介して印加するとともに、映像信号の極性を所定の周期で反転させる第2駆動部とを備えている。第2駆動部は、信号電圧の印加に先立って、相対的に振幅の大きな第1プリチャージ信号電圧と、相対的に振幅の小さな第2プリチャージ信号電圧とを順次、信号線に印加する。第2駆動部は、さらに、第1プリチャージ信号電圧の印加に起因する、画素から信号線への電流リーク量が所定の水平期間ごとに他の期間よりも小さくなるように、第1プリチャージ信号電圧の印加を制御する。
