OLED DRIVE POWER SUPPLY DEVICE

摘要

Disclosed is an OLED drive power supply device, comprising a power supply board which is connected to a mainboard and an OLED screen. The power supply board comprises a standby circuit, a time-sequence control module, a first conversion module, a second conversion module and a PFC circuit, wherein the standby circuit is connected to the time-sequence control module and the mainboard; the time-sequence control module is connected to the PFC circuit, the mainboard, the first conversion module and the second conversion module; and the first conversion module and the second conversion module are both connected to the mainboard and the PFC circuit. In the present invention, a high-voltage direct current is respectively converted into a first voltage and a second voltage via the first conversion module and the second conversion module, so as to supply power to the mainboard and the OLED screen, so that the first voltage and the second voltage are independent from each other, thereby satisfying the requirement of an OLED for the stability of the output of a power supply and improving the picture quality thereof; and the time-sequence control module enables the OLED screen to be lighted up after a power-on/power-off signal and an enable signal are both stabilized, thereby changing the power-on/power-off time sequence of a traditional power supply, so that the power supply can adapt to the fast response characteristic of the OLED.
