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.

Abstract: An integrated device includes a semiconducting substrate having a matrix of active pixels formed therein. Each active pixel includes an OLED diode, a first nMOS transistor having its source coupled to an anode of the OLED diode, and a refresh circuit coupled to a gate of the first nMOS transistor. The first nMOS transistor has its source and its substrate coupled together. The first nMOS transistor is situated in and on a first part of the semiconductor substrate, and the refresh circuit is situated in and on a second part of the semiconductor substrate, with the first part and the second part being electrically insulated from one another.
