Abstract
The present invention provides a method of driving a gas discharge display apparatus for displaying gray-scale display levels finer than those achieved by the conventional methods, and also to provide a gas discharge display apparatus with a driver capable of performing such a driving method. An opposed discharge between the sustaining electrode and the address electrode in addition to the conventional surface discharge is generated for the light emission from the fluorescent material in light emitting tubes. The method and the apparatus effect improvements in finer gray-scale display levels than those by the conventional methods.
