Abstract
A display pixel including a light-emitting diode, a circuit for driving the light-emitting diode, and first, second, third, and fourth conductive pads. The light-emitting diode is powered with a first voltage received between the first and second pads. The driver circuit controls the light-emitting diode based on first and second binary signals. The first signal is received between the third and second pads and alternates between a second voltage lower than the first voltage, and a third voltage, lower than the second voltage. The second signal is received between the fourth and second pads and alternates between the second voltage and the third voltage. The display pixel comprises a circuit for delivering a power supply voltage of the driver circuit, based on the first and second signals.
