Abstract
(EN)
An OLED display device and control method therefor, relating to the technical field of display. The display device comprises: a first switch unit (530), which is electrically connected to a standby voltage terminal (P1) of a power panel (510) and a standby voltage terminal (P2) of a main chip (520) and used for controlling connecting and disconnecting of the standby voltage terminal (P1) of the power panel (510) and the standby voltage terminal (P2) of the main chip (520); a first control unit (540), which is electrically connected to the first switch unit (530) and used for controlling turn-on and turn-off of the switch unit (530) in response to an alternating current detection signal (AC_DETECT) outputted by the power panel (510) and a direct current detection signal (DC_DETECT) outputted by the main chip (520), wherein the alternating current detection signal (AC_DETECT) is used for detecting whether a signal of alternating current dump or alternating current power-on is received, and the direct current detection signal (DC_DETECT) is used for detecting whether a signal of direct current dump or direct current power-on is received. A standby voltage can be quickly disconnected during the alternating current dump, so as to normally start up the display device during the alternating current power-on and ensure normal standby during the direct current dump.

Dispositif d'affichage OLED et son procédé de commande, se rapportant au doamine technique de l'affichage. Le dispositif d'affichage comprend : une première unité de commutation (530), qui est connectée électriquement à une borne de tension de veille (P1) d'un panneau d'alimentation (510) et à une borne de tension de veille (P2) d'une puce principale (520) et utilisée pour commander la connexion et la déconnexion de la borne de tension de veille (P1) du panneau d'alimentation (510) et de la borne de tension de veille (P2) de la puce principale (520) ; une première unité de commande (540), qui est connectée électriquement à la première unité de commutation (530) et utilisée pour commander l'activation et la désactivation de l'unité de commutation (530) en réponse à un signal de détection de courant alternatif (AC_DETECT) sorti par le panneau d'alimentation (510) et à un signal de détection de courant continu (DC_DETECT) émis par la puce principale (520), le signal de détection de courant alternatif (AC_DETECT) étant utilisé pour détecter si un signal de décharge de courant alternatif ou de mise sous tension à courant alternatif est reçu, et le signal de détection de courant continu (DC_DETECT) étant utilisé pour détecter si un signal de décharge de courant continu ou de mise sous tension à courant continu est reçu. Une tension de veille peut être rapidement déconnectée pendant la décharge de courant alternatif, de manière à démarrer normalement le dispositif d'affichage pendant la mise sous tension à courant alternatif et à assurer une veille normale pendant la décharge de courant continu.
