Title (EN) FLEXIBLE DISPLAY DEVICE AND METHOD FOR DETECTING BENDING STATE THEREOF
(FR) DISPOSITIF D'AFFICHAGE FLEXIBLE ET PROCÉDÉ DE DÉTECTION D'ÉTAT DE PLIAGE
(JA) フレキシブル表示装置およびその屈曲状態検出方法
Abstract:
(EN) An organic EL panel 10 is a display panel which can be bent and includes a plurality of pixel circuits 60, each of which has a light emitting element and a driving element. A data line driving circuit 15 performs an operation for writing a voltage to a control terminal of the driving element and an operation for measuring the current flowing through the driving element by driving a data line with respect to the pixel circuit 60 selected by a scan line driving circuit 14. A bending detecting unit 90 detects the bending state of the organic EL panel 10 on the basis of the result of measuring the current flowing through the driving element. A correcting unit 80 corrects an image signal VS1 on the basis of the detected bending state. Accordingly, the bending state of a screen is detected and a change in brightness or color is prevented when the screen is bent.
(FR) Ce panneau EL organique (10) est un panneau d'affichage qui peut être plié et comprend une pluralité de circuits de pixels (60), chacun d'eux comprenant un élément électroluminescent et un élément de commande. Un circuit de commande de ligne de données (15) effectue une opération permettant d'écrire une tension dans une borne de commande de l'élément de commande ainsi qu'une opération permettant de mesurer le courant circulant dans l'élément de commande en commandant une ligne de données par rapport au circuit de pixels (60) sélectionné par un circuit de commande de ligne de balayage (14). Une unité de détection de pliage (90) détecte l'état de pliage du panneau EL organique (10) d'après le résultat de mesure du courant circulant par l'élément de commande. Une unité de correction (80) corrige un signal d'image VS1 d'après l'état de pliage détecté. Par conséquent, l'état de pliage d'un écran est détecté et un changement de luminosité ou de couleur est évité lorsque l'écran est plié.
(JA) 有機ELパネル10は、発光素子と駆動素子を有する複数の画素回路60を含む屈曲可能な表示パネルである。データ線駆動回路15は、データ線を駆動することにより、走査線駆動回路14によって選択された画素回路60について、駆動素子の制御端子に電圧を書き込む動作と、駆動素子を流れる電流を測定する動作とを行う。屈曲検出部90は、駆動素子を流れる電流を測定した結果に基づき、有機ELパネル10の屈曲状態を検出する。補正部80は、検出された屈曲状態に基づき映像信号VS1を補正する。これにより、画面の屈曲状態を検出し、画面屈曲時の輝度や色の変化を防止する。
