Abstract
In a picture display device driven with an active matrix in which the selection lines (11) are capacitively coupled to electrodes (6) of the picture elements, the voltage across these picture elements is accurately adjusted by discharging or charging the associated capacitances first to beyond the range of transition (22) in the transmission/voltage characteristic.
