Abstract
The present invention provides a power supply circuit and an OLED display device, belongs to the field of OLED display technology, and can solve the problem that existing power supply circuits have low efficiency when brightness of the OLED display panel is low. The power supply circuit is used for proving an anode voltage and a cathode voltage for an OLED display panel, a difference between the anode voltage and the cathode voltage being a driving voltage, and the power supply circuit includes: a current detection unit for generating a control signal according to a driving current of the OLED display panel; and a driving voltage unit for generating, according to the control signal, a driving voltage positively correlated with the driving current, and including an anode voltage unit for generating an anode voltage and a cathode voltage unit for generating a cathode voltage.
