The device comprising a video processing circuit (7) for processing the video data received, a correspondence memory (8) for transcoding these data, a video memory (9) for storing the transcoded data, the video memory being linked to column drivers (10) in order to control the column addressing of the plasma panel on the basis of column control words, a control circuit (11) for the line drivers (12), is characterized in that the control circuit for the line drivers simultaneously selects at least two successive lines during the transmission by the column drivers (10) of at least one of the bits of the column control words relating to one of these lines.
A method for addressing cells arranged as a matrix array, each cell being situated at the intersection of a line and a column, the array having line inputs and column inputs for displaying grey levels defined by video words making up a digital video signal, wherein the column inputs each receive a control word for this column corresponding to the video word relating, for this column, to the addressed line, this work being made up of n bits transmitted sequentially, each bit triggering or not triggering, depending on its state, the selection of the cell of the addressed line and of the corresponding column for a time proportional to the weight of this bit within the word, wherein all the lines are independently selected for at least one of the bits of the column control word, and wherein at least two lines are simultaneously selected for at least another one of the bits of the column control word relating to the two lines.
