  • Patent number: 8362984
    Abstract: 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.
    Type: Grant

  • Patent number: 8094101
    Abstract: Panel comprising display drivers which, each 1??, 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.

  • Patent number: 7924250
    Abstract: 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: an inverse bias switch for each emitter, said inverse bias switch being connected, on the one hand, to each modulator and, on the other hand, to the or each inverse bias voltage generator; and control electrodes able to drive all the inverse bias switches of a row of emitters. The invention also relates to a method of driving this device.
