Abstract
A device includes a matrix of active pixels. Each active pixel includes an OLED and a control circuit configured to refresh the active pixel and including at least one transistor having a first conduction terminal coupled to a supply line and a second conduction terminal coupled to the OLED. Supply circuitry is configured to apply a supply voltage to the supply line of each active pixel during the refreshing of the active pixel and for a time period less than a duration of the refreshing of the active pixel.
