Title
(EN) OLED DRIVE POWER DEVICE AND OLED TELEVISION
(FR) DISPOSITIF DE PUISSANCE D'ATTAQUE OLED ET TÉLÉVISION OLED
(ZH) 一种 OLED 驱动电源装置及 OLED 电视
Abstract
(EN) An organic light-emitting diode (OLED) drive power device and OLED television, the OLED drive power device comprising a power board (10) connected to a motherboard (20) and an OLED screen logic board (30), the power board (10) being provided thereon with a power supply circuit (11), a first conversion module (12), a second conversion module (13), a changeover switch (14) and a power factor correction (PFC) circuit (15); after power is connected, the power supply circuit (11) starts the PFC circuit (15) to output a high-voltage direct current according to an on-off signal output by the motherboard (20), the first conversion module (12) converts the high-voltage direct current into a first voltage and a second voltage to power the motherboard (20), and the changeover switch (14) converts the first voltage into a first enable voltage to power the OLED screen logic board (30); after a preset period of time, the second conversion module (13) converts the high-voltage direct current into a second enable voltage to power the OLED screen logic board (30) so as to light an OLED screen. Redesigning the architecture of the power board (10) eliminates a need for a standby circuit and streamlines circuits, which not only meets the power output stability and timing requirements of an OLED, but also successfully reduces the size of the power board (10), thereby reducing cost of power and benefiting the popularization of the OLED.
(FR) L'invention concerne un dispositif de puissance d'attaque de diodes électroluminescentes organiques (OLED) et une télévision OLED, le dispositif de puissance d'attaque OLED comprenant une carte d'alimentation (10) connectée à une carte mère (20) et une carte logique d'écran OLED (30), la carte d'alimentation (10) comportant un circuit d'alimentation électrique (11), un premier module de conversion (12), un second module de conversion (13), un inverseur (14) et un circuit (15) de correction du facteur de puissance (PFC). Après le début de l'alimentation, le circuit d'alimentation électrique (11) allume le circuit PFC (15) pour émettre un courant continu à haute tension en fonction d'un signal marche/arrêt émis par la carte mère (20), le premier module de conversion (12) convertit le courant continu à haute tension en une première et une seconde tension pour alimenter la carte mère (20), et l'inverseur (14) convertit la première tension en une première tension d'activation pour alimenter la carte logique d'écran OLED (30). Après une période prédéfinie, le second module de conversion (13) convertit le courant continu à haute tension en une seconde tension d'activation pour alimenter la carte logique d'écran OLED (30) de façon à allumer l'écran OLED. Cette nouvelle conception de l'architecture de la carte d'alimentation (10) rend tout circuit de secours inutile et simplifie les circuits, et cela satisfait non seulement les exigences de stabilité de sortie de puissance et de synchronisation d'une OLED, mais réduit également la taille de la carte d'alimentation (10), ce qui diminue les coûts en énergie et profite à la généralisation de l'OLED.
