Title (EN) COLOR DISPLAY DEVICE
(FR) DISPOSITIF D’AFFICHAGE COULEUR
(JA) カラー表示装置
Abstract:
(EN) Disclosed is a color display device comprising a total fluctuation calculation unit (23) contained in a display control circuit (200).  On the basis of a display data signal (DAT) from the outside, the total fluctuation calculation unit (23) calculates the total of the quantities of potential fluctuations of a driving video signal to be applied for one frame to each video signal line.  For a pixel forming portion, to which a display data signal (DATp) (corresponding to a next display line of one frame before) received from a frame memory (22) is fed, a data correction unit (24) makes a correction to compensate the influence which is caused by the potential fluctuations of adjacent another video signal line not connected with the image forming portion.  Thus, the color display device of a delta array type can reduce or eliminate a transverse streak, which is caused by the potential fluctuations of said another video signal line, by the simple constitution.
(FR) L’invention concerne un dispositif d’affichage couleur comprenant une unité de calcul de fluctuations totales (23) contenue dans un circuit de commande d’affichage (200). En fonction d’un signal de données d’affichage (DAT) venant de l’extérieur, l’unité de calcul de fluctuations totales (23) calcule le total des quantités de fluctuations potentielles d’un signal vidéo d’actionnement devant être appliqué pour une trame à chaque ligne de signal vidéo. Pour une partie de formation de pixel, vers laquelle est envoyé un signal de donnes d’affichage (DATp) (correspondant à une ligne d’affichage suivante d’une trame précédente) reçu d’une mémoire de trames, une unité de correction de données (24) effectue une correction afin de compenser les influences dues aux fluctuations potentielles d’une autre ligne de signal vidéo adjacente non connectée à la partie de formation d’image. Ainsi, le dispositif d’affichage couleur de type réseau delta permet de réduire ou d’éliminer une strie transversale due aux fluctuations potentielles de ladite autre ligne de signal vidéo du fait de sa structure simple.
(JA)  本発明の表示装置における表示制御回路(200)に含まれる変動総量算出部(23)は、外部からの表示データ信号(DAT)に基づき、1フレームの間に各映像信号線に対して印加されるべき駆動用映像信号の電位変動量の総量を算出する。データ補正部(24)は、フレームメモリ(22)から受け取った(1フレーム前の次の表示行に対応する)表示データ信号(DATp)を与えるべき画素形成部に対して、これに接続されない隣り合う他映像信号線の電位変動により生じる影響を補償する補正を行う。このことにより、本デルタ配列型のカラー表示装置は、簡単な構成で上記他映像信号線の電位変動により生じる横スジを低減または解消することができる。
