Process for controlling a display panel and display device using this process

Process for controlling a display panel comprising cells defined by the intersection of two networks of crossed electrodes, these cells possessing two states, one written, the other erased, the process consisting:

• in applying a substantially square-wave hold signal on either side of a middle potential to all the cells, with the aim of producing a hold discharge with regard to the cells in the written state, at the termination of the edges leading to an extreme porch,
• and in applying an addressing signal, superimposed on the hold signal, in succession to the electrodes of a network, this addressing signal comprising a semi-selective erase signal, generating, in respect of the cells in the written state and which are linked to the selected electrode, an erase discharge, characterized in that the erase discharge occurs at the termination of an edge leading to an extreme porch of the hold signal alone, this erase discharge disabling the hold discharge which should have occurred at the termination of this edge leading to the extreme porch of the hold signal alone.
