专利汇可以提供Split-sustainer operation for gaseous discharge display panels专利检索，专利查询，专利分析的服务。并且There is disclosed an improved sustainer supply system that allows more economical addressing techniques for gaseous discharge display panels. There is particularly disclosed a sustainer supply system wherein the panel discharge currents need not be carried by the addressing drive circuitry. According to the invention each panel electrode or conductor line is addressable by a resistor-diode addressing matrix. The invention provides an addressable sink circuit which sinks current from any diode resistor combination.，下面是Split-sustainer operation for gaseous discharge display panels专利的具体信息内容。

权利要求

1. A system for supplying electrical operating voltage to conductor arrays of a gas discharge display panel including (1) discharge condition manipulating voltages, and (2) periodic sustain voltages, a resistor diode matrix means for addressing selected ones of the conductors in at least one of said conductor arrays, said resistor-diode addressing matrix including a plurality of resistor-diode gate elements with a node point between each resistor-diode element, means connecting each node point to a conductor in said array, a plurality of resistor voltage pulsers, means connecting the opposite end of selected N groups of said resistors to a selected one of said resistor voltage pulsers, a plurality of addressable sink circuits, each addressable sink circuit being connected to the opposite ends, respectively, of a selected group of diodes of said resistordiode elements, and controlled on entry and removal of information to said panel to sink current from any ''''M'''' nonadjacent diode-resistor elements where M X N equals the total number of conductors on said panel, means for supplying said periodic sustaining voltage including a direct current sustain power supply, having a pair of output terminals, an up sustain transistor switch connected between one terminal of said supply and an intermediate point, means coUpling said intermediate point to the node point of all said resistor-diode elements, a down sustain transistor switch means, means coupling said down sustain switch to the sides of said diodes opposite said node point.

2. The invention defined in claim 1 including a further transistor switch means connected to said intermediate point for connecting said intermediate point to a neutral voltage level for erase of information from said panel.

3. The invention defined in claim 1 wherein said means coupling said intemediate point to said node point includes a diode.

4. The invention defined in claim 3 wherein said means coupling said down sustain switch to the sides of said diodes opposite said node points includes a diode.

5. The invention defined in claim 1 wherein said means coupling said down sustain switch to the sides of said diodes opposite said node points is consitituted by a further diode.

6. The invention defined in claim 1 including a further diode connected between said down sustainer switch means the resistor ends of said resistor-diode gate elements opposite the node points.
