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.
