description An organic light-emitting diode (OLED) drive power device and OLED television, OLED drive power device comprising power board connected to motherboard and OLED screen logic board, power board having power supply circuit, first conversion module, second conversion module, changeover switch and power factor correction (PFC) circuit thereon; after powered, power supply circuit starts PFC circuit to output high-voltage direct current (HVDC) according to on-off signal output by motherboard, first conversion module converts HVDC into first voltage and second voltage to power motherboard, and first voltage is converted to power OLED screen logic board; after preset time period, HVDC is converted to power OLED screen logic board to light OLED screen. Redesigning architecture of power board eliminates need for standby circuit and streamlines circuits, meets power output stability and timing requirements of OLED, reduces power board size, reduces power cost and benefits OLED popularization.
