DEFINITION

Classification: 315/169.1

Diverse-type energizing or bias supplies to different electrodes:

(under subclass 167) Subject matter in which the discharge device is connected so that the discharge path between one anode and cathode is supplied with energizing or bias current from one source of supply and a different discharge path between another anode and cathode path is supplied with current from another source of supply of a diverse type.

(1) Note. Distinction should be made between subject matter claiming energizing or bias potentials which may turn on a display either entirely or in a nonimage mode, classifiable here, and subject matter claiming selective energizing, pulsing or other input responsive signaling which results in a display producing a light image or message which subject matter is classifiable in Class 345.

(2) Note. The type of current (energizing or bias) supplies which are considered to be diverse are defined in Note (2) of the definition of subclass 160. Other examples of diverse current sources may be lines carrying different "phases" of a clock pulse source, or lines carrying different time based pulses.

168, for this subject matter where the discharge device is provided with an auxiliary discharge electrode, one source of current being connected to the principal cathode and the principal electrode and one of the principal electrodes.

337, for systems wherein the load device is a plural cathode and/or anode discharge device, the discharge device being supplied with current for the different anodes or cathodes from a single source of supply and means being provided so that different potentials are maintained at different anodes or cathodes.
