Abstract
A display pixel including at least one light-emitting diode, a circuit for driving the light-emitting diode, and first, second, third, and fourth conductive pads. The driver circuit is powered with a first power supply voltage received between the first and second pads. The light-emitting diode is powered with a first binary signal, received between the third and second pads, and alternating between a second power supply voltage, greater than the first voltage, and a third voltage, smaller than the first voltage. The driver circuit is configured to determine a digital signal based on the values of a second binary signal on the fourth pad received during each of first pulses of the first binary signal at the third voltage and to control the light-emitting diode from the digital signal.
