Abstract:
(EN) This liquid crystal display device comprises: a pixel array comprising multiple rows of gate lines, multiple columns of source lines, multiple switches, and multiple liquid crystal cells; gate driver ICs connected to the gate lines; source driver ICs connected to the source lines; a timing control IC that controls the operation timings of the gate driver ICs and the source driver ICs; and a system power supply IC that supplies a power supply voltage to the source driver ICs. The timing control IC and the system power supply IC are each have a function for detecting an abnormality in the gate driver ICs and/or an abnormality in the source driver ICs.
(FR) L'invention concerne un dispositif d'affichage à cristaux liquides comprenant : une matrice de pixels comprenant une pluralité de rangées de lignes de grille, une pluralité de colonnes de lignes de source, une pluralité de commutateurs, et une pluralité de cellules de cristaux liquides; des circuits intégrés de commande de grille connectés aux lignes de grille; des circuits intégrés de commande de source connectés aux lignes de source; un circuit intégré de commande de synchronisation qui commande les synchronisations de fonctionnement des circuits intégrés de commande de grille et des circuits intégrés de commande de source; et un circuit intégré d'alimentation électrique de système qui fournit une tension d'alimentation électrique aux circuits intégrés de commande de source. Le circuit intégré de commande de synchronisation et le circuit intégré d'alimentation électrique de système ont chacun une fonction pour détecter une anomalie dans les circuits intégrés de commande de grille et/ou une anomalie dans les circuits intégrés de commande de source.
(JA) 液晶表示装置は、複数行のゲート線、複数列のソース線、複数個のスイッチ、及び複数個の液晶セルを有する画素アレイと、前記ゲート線に接続されるゲートドライバICと、前記ソース線に接続されるソースドライバICと、前記ゲートドライバIC及び前記ソースドライバICの動作のタイミングを制御するタイミング制御ICと、前記ソースドライバICに電源電圧を供給するシステム電源ICと、を有する。前記タイミング制御IC及びシステム電源ICそれぞれが、前記ゲートドライバICの異常及び前記ソースドライバICの異常を検出する機能を有する。
