A driving circuit of an OLED diode is inserted between a first and a second voltage reference and having at least one input terminal receiving an input voltage signal and an output terminal for the generation of a driving current of the OLED diode, the driving circuit having at least one driver transistor having a first conduction terminal connected to the first voltage reference, a second conduction terminal connected to the output terminal and a control terminal connected to at least one first capacitor and one second capacitor. The first capacitor is inserted between this control terminal and an inner circuit node and the second capacitor is inserted between the inner circuit node and the second voltage reference, the driving circuit 10 further including: a first switch inserted between the input terminal and the inner circuit node; a second switch inserted between the first conduction terminal and control terminal of the driver transistor, and a third switch inserted between the inner circuit node and the second voltage reference, in parallel to the second capacitor, as well as a fourth switch inserted between the first voltage reference and the first conduction terminal of the driver transistor.
