Abstract
A method of controlling an optoelectronic device including display pixels arranged in rows and in columns. The optoelectronic device further includes first electrodes, each connected to the display pixels of at least one row, second electrodes, each connected to the display pixels of at least one column, and a circuit for controlling the first and second electrodes. The method includes, in a first phase, the activation of the display pixels connected to one of the first electrodes and to one of the second electrodes by the following steps, simultaneously carried out: taking one of the first electrodes to a first potential, the other first electrodes being maintained at a second potential smaller than the first potential; and taking one of the second electrodes to a third potential smaller than the second potential, the other second electrodes being maintained at a fourth potential greater than the third potential and smaller than the second potential.
