Abstract
A driver circuit for driving a plasma display panel comprising a plurality of cells arranged in a matrix of lines and columns; comprising a set of driver output stages connected to line or column electrodes to which a first electrode of cells of a same line or a same column are connected, respectively. The driver circuit includes a detection device for detecting a short circuit between two or more of the outputs of the driver output stages. It allows to test for alignment faults in the flexible cable connecting together the driver module housing incorporating the driver circuit and the electrodes of the plasma display panel.
