OLED drive power supply and OLED television

An OLED drive power supply, comprising:

• a power supply board connected with a mainboard and an OLED screen, wherein the power supply board comprises a power supply circuit, a first conversion module, a second conversion module and a switch;
• after powering on, the power supply circuit starts the first conversion module according to an on-off signal output from the mainboard, the first conversion module outputs a high-voltage direct current to the second conversion module, the first conversion module outputs a first voltage and a second voltage to supply power to the mainboard, and the switch converts the first voltage into a first enabling voltage before outputting to the OLED screen for power, according to a first enabling signal output from the mainboard;
• after a preset time, the mainboard outputs a second enabling signal to the power supply circuit, the power supply circuit controls the second conversion module to start according to the second enabling signal, the second conversion module converts the high-voltage direct current into a second enabling voltage to supply power to and light up the OLED screen;
• the first conversion module comprises a bridgeless PFC circuit and an auxiliary path LLC control circuit integrated in a same semiconductor chip package, the bridgeless PFC circuit starts and outputs a high-voltage direct current to the auxiliary path LLC control circuit, and the auxiliary path LLC control circuit converts the high-voltage direct current into the first voltage and the second voltage before outputting to the mainboard for power.
