1. Display pixel for a display screen, comprising at least one light-emitting diode, a circuit for driving the light-emitting diode, and first, second, third, and fourth electrically-conductive pads, the light-emitting diode being powered with a first voltage received between the first and second electrically-conductive pads, the driver circuit being configured to control the light-emitting diode from first and second binary signals, the first binary signal being received between the third and second electrically-conductive pads, the first binary signal alternating between a second voltage, lower than the first voltage, and a third voltage, lower than the second voltage, the second binary signal being received between the fourth and second electrically-conductive pads, the second binary signal alternating between the second voltage and the third voltage, the display pixel further comprising a circuit for delivering a power supply voltage, equal to within 10% to the second voltage, for the powering of the driver circuit, based on the first and second binary signals.
