A drive power supply, display drive circuit, and organic light emitting diode (OLED), the drive power supply comprising: a booster module (3) and a voltage regulator module (4); the voltage regulator module (4) is in connection with the booster module (3); the booster module (3) is used for boosting an initial voltage (VCC) input from a VCC input terminal of the drive power supply to form a reference voltage (VDD1), and outputting VDD1 to the voltage regulator module (4); the voltage regulator module (4) is used for regulating VDD1 according to the color of a pixel unit to be driven to form a plurality of drive voltages respectively, and pixel units of different colors correspond to different drive voltages. The drive power supply may provide a corresponding drive voltage according to the color of the pixel unit to be driven, such that the voltage obtained at a drive transistor in the drive circuit of the pixel unit is reduced with respect to the voltage obtained at a drive transistor in the prior art, thus reducing power consumption of the drive transistor, thereby reducing power consumption of the overall display drive circuit. |
