  • Publication number: 20110175887
    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 being reached 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 being reached therebetween.
