Pulse Control Apparatus for Plasma Display Selection.
Abstract
The patent application describes pulse apparatus for controlling the selection pulse in a plasma electrode selection matrix wherein a driver receiving a voltage from supply V sub w is turned on to charge capacitor C through resistor R. At time T, when the voltage has essentially reached V sub w the driver is turned off, and a diode clamp is turned on returning the voltage rapidly to zero. In a modification, an additional diode and voltage supply V sub w are added at the output of the diode clamp. The driver is connected to voltage supply V sub c that is about fifty percent higher than the voltage supply V sub w. When the capacitor voltage reaches V sub w, the diode connected to V sub w conducts and clips the pulse amplitude so that it does not exceed V sub w. The driver is then turned off and the clamp is turned on to return the voltage to zero.
