Abstract:
1. An active matrix for an organic light-emitting diode display screen, comprising: pixels arranged in rows and in columns, each pixel including, each pixel is disposed between two row select lines of the matrix, with the first current driver disposed between a first of these two row select lines and the pixel electrode, said first row select line forming the gate of the first switching transistor of the first current driver and the second current driver is disposed between a second of these two row select lines and the pixel electrode, said second row select line forming the gate of the first switching transistor of the second current driver; a source-drain electrode of the current control transistors of the first and second current drivers is formed by a Vdd supply bus produced on the source-drain metal level, and the other source-drain electrode of the control transistors is formed by an excrescence of the pixel electrode on the source-drain metal level; and each column data line is disposed between two columns of pixels of the matrix and formed from said source-drain metal level and said gate metal level, said gate metal level being used along the pixel electrodes and said source-drain metal level being used in zones between said pixel electrodes where the first switching transistors of said first and second current drivers are disposed.
