    • A circuit for controlling illumination means in a display includes illumination means arranged in a series-connection that are supplied with an essentially constant current. For individually controlling the illumination means, switches are provided for bypassing individual illumination means, maintaining the essentially constant current in the series-connection. The switches are floating with respect to a ground potential. A coupling means is thus provided for proper control of the switches. In a development of the invention a floating local power supply is provided with each illumination means and switch for operating the switch. The local power supply is, in one embodiment, powered by the control signal that is used for controlling the bypass switch. In another embodiment provision is made for supplying power to the floating local power supply. A driving method according to the embodiments of the circuit is also described.
    • 用于控制显示器中的照明装置的电路包括布置成串联连接的照明装置,所述照明装置被提供有基本上恒定的电流。 为了单独控制照明装置,提供开关以绕过单独的照明装置,从而在串联连接中保持基本上恒定的电流。 开关相对于地电位是浮动的。 因此提供耦合装置以适当地控制开关。 在本发明的一个发展中,浮动的本地电源设有用于操作开关的每个照明装置和开关。 在一个实施例中,本地电源由用于控制旁路开关的控制信号供电。 在另一个实施例中,规定为浮动本地电源供电。 还描述了根据电路的实施例的驱动方法。

    • The present invention concerns a device for generating a rectangular sustain voltage between the line scanning electrodes (Y) and the line common electrodes (Z) of luminous cells in a plasma panel. The device includes a first sustain amplifier (11 ) connected to the line scanning electrode (Y) of the cells to produce the transitions of the first sustain voltage signal, and a second sustain amplifier (13) connected to the line common electrode (Z) of the cells to produce the transitions of the second sustain voltage signal. It also includes an insulated voltage supply circuit which is connected directly to the line scanning electrodes (Y) and to the line common electrodes (Z) of the cells in order to hold the end-of-transition voltage on said line scanning electrodes (Y) and said line common electrodes (Z).
