Title
(EN) DRIVING METHOD, DRIVING CIRCUIT AND DRIVING APPARATUS FOR A DISPLAY SYSTEM
(FR) PROCEDE, CIRCUIT ET APPAREIL D'ATTAQUE POUR SYSTEME D'AFFICHAGE
Abstract
(EN)
A table-based driving circuit for displays that switches between a normal operational mode and a read table block mode. The driving circuit comprises an address sequencer and a memory. The memory comprises the full table of individual sequences, such as interlacing or color-sequential sequence. In the read table mode, the next upcoming addresses are read, i.e. are downloaded, from the memory into an address table register in the address sequencer. In the normal operational mode, the address sequencer generates the addresses for the video data to be stored in the memory or to be displayed.
(FR)
Selon l'invention, un circuit d'attaque basé sur un tableau et destiné aux affichages permet d'effectuer une commutation entre un mode de fonctionnement normal et un mode de blocage de tableau de lecture. Ce circuit d'attaque comprend un séquenceur d'adresses et une mémoire. Cette mémoire comporte l'ensemble du tableau de séquences individuelles, telles qu'une séquence d'entrelacement ou séquentielle de couleurs. En mode de tableau de lecture, les adresses suivantes sont lues, par exemple, elles sont téléchargées, de la mémoire dans un registre de tableau d'adresses dans le séquenceur d'adresses. En mode de fonctionnement normal, le séquenceur d'adresses permet d'engendrer les adresses destinées aux données vidéo à stocker dans la mémoire ou à afficher.
