Abstract
(EN)
A circuit structure (100) comprises: a control circuit (110) including a first terminal (111), a second terminal (112), and a control terminal (113); a switch circuit (120) including a first interface (121), a second interface (122) and a control interface (123); a driving power line (150) connected to the control terminal (113) of the control circuit (110) and configured to provide a driving power voltage for turning on the first terminal (111) and the second terminal (112) of the control circuit (110) at a working stage; and a first voltage line (140) connected to the first terminal (111) of the control circuit (110) and configured to provide a first voltage to the control interface (123) of the switch circuit (120) through the control circuit (110) when the first terminal (111) and the second terminal (112) of the control circuit (110) are turned on, so as to disconnect the first interface (121) and the second interface (122) of the switch circuit (120). The circuit structure (100) avoids a phenomenon of power-on flash by modifying a voltage on a data line of a display device (10) before normal operation.

Selon l'invention, une structure de circuit (100) comprend : un circuit de commande (110) comprenant une première borne (111), une seconde borne (112), et une borne de commande (113) ; un circuit de commutation (120) comprenant une première interface (121), une seconde interface (122) et une interface de commande (123) ; une ligne de puissance d'attaque (150) connectée à la borne de commande (113) du circuit de commande (110) et configuré pour fournir une tension de puissance d'attaque pour mettre sous tension la première borne (111) et la seconde borne (112) du circuit de commande (110) u niveau d'un étage de travail ; et une première ligne de tension (140) connectée à la première borne (111) du circuit de commande (110) et configuré pour fournir une première tension à l'interface de commande (123) du circuit de commutation (120) à travers le circuit de commande (110) lorsque la première borne (111) et la seconde borne (112) du circuit de commande (110) sont sous tension, de manière à déconnecter la première interface (121) et la seconde interface (122) du circuit de commutation (120). La structure de circuit (100) évite un phénomène de flash de mise sous tension par modification d'une tension sur une ligne de données d'un dispositif d'affichage (10) avant le fonctionnement normal.
