ABSTRACT:
A display screen is controlled through successive scans of the display screen. Each scan of the display screen includes a successive selection of rows of the display screen. For each row selected, and in accordance with a normal selection, a first column selection mode is implemented wherein a first selection signal is generated for the column, that first selection signal going from a first state towards a second state with an intermediate plateau level therebetween. In an alternative operation, a second column selection mode is provided which replaces the first column selection mode, the second column selection mode including the generation of a second selection signal going from the first state to the second state without any intermediate plateau level. At least at the start of each scan, the first selection mode is replaced by the second selection mode and this second selection mode is maintained for a given column, at the latest, for as long as no deselection of the column has been effected.
