Abstract
An organic light-emitting display screen includes n×m picture dots organized in a matrix with m rows and n columns. Each picture dot includes an organic diode and first and second driver circuits for the diode. Each of the first and second driver circuits includes a driving transistor connected between a reference voltage and one electrode of the diode, a switching transistor for switching a gate voltage onto a gate of the driving transistor, and a capacitor connected to the gate of the driving transistor. A circuit for addressing each of the n×m picture dots, to control alternately and simultaneously a recovery phase on one driver circuit and a display phase on the other driver circuit of a picture dot, includes as row select lines, only m row select lines, one per row of picture dots, and/or as data lines, only n data lines, one per column of picture dots.
