1. A method of driving an active matrix display device having sets of row and column address conductors and an array of electro-optic display elements operable to produce a display each of which is connected in series with a two terminal non-linear device between a row address conductor and a column address conductor, in which a selection voltage signal is applied to each row address conductor during a row selection period to select a row of display elements and data voltage signals are applied to the column address conductors whereby the selected display elements are driven to voltage levels according to the data voltage signals, characterised in that the selection signal supplied to a row address conductor comprises a voltage pulse signal whose magnitude increases gradually in a controlled fashion to a maximum selection voltage amplitude during the row address period.
