A method comprising emission periods during which a predetermined emission voltage, which presents a first polarity, is applied and sustained at the control terminal of at least one driver of said panel, and depolarization periods during which a predetermined depolarization voltage, which presents a second polarity, opposite to the first polarity, is applied and sustained at the control terminal of at least one driver of said panel, the address signals of the circuits of said panel being transmitted by capacitive coupling of the address electrodes to the control terminals of these circuits. The invention makes it possible to use conventional and inexpensive means of controlling the address electrodes.

Method for controlling a display panel by capacitive coupling

Panel comprising display drivers which, each&#x2033;', comprise a select switch and a clamping switch which are controlled by the same select electrode, and a coupling capacitor for transiently coupling the control terminal of this circuit C to an address electrode. A control method comprising emission periods and depolarization periods, where all the address signals have the same polarity. The invention makes it possible in particular to use conventional and inexpensive means of controlling the address electrodes.

Display panel and control method using transient capacitive coupling

The invention relates to an image display device with active matrix comprising a number of light emitters forming a network divided into rows and columns; a current modulator for each emitter; and at least one inverse bias voltage generator. This device is characterized in that it also comprises: The invention also relates to a method of driving this device.
