The organic light emitting diode display panel of the present invention includes: an array substrate with a plurality of sub-pixels; a power supply for providing a power supply voltage to the sub-pixels in the array substrate; a first lead connecting the array substrate and the power supply; a current detection unit for for detecting the current in the first lead; a control unit for controlling the output voltage of the power supply according to the detection result of the current detection unit.

Description

technical field [0001] The invention belongs to the technical field of organic light emitting diode (OLED) display, and in particular relates to an organic light emitting diode display panel, a driving method thereof, and an organic light emitting diode display device. Background technique [0002] In an OLED display panel, each sub-pixel has an OLED for emitting light, and the brightness of the OLED is determined by the current flowing through it and the voltage applied to it. Wherein, the current flowing through the organic light emitting diode is determined by the signal on the data line corresponding to the organic light emitting diode, so that the brightness of each sub-pixel can be controlled through the data line; voltage is determined by the supply voltage (V dd ), and the power supply voltage of each sub-pixel is uniformly provided by a power supply located outside the array substrate. [0003] Apparently, the power supply needs to be connected to the array substr...
