UN GENERADOR DE VOLTAJE MANTENIDO ESCALONADO, PARA UN PANEL DE PRESENTACION VISUAL DE DESCARGA LUMINOSA EN GAS. |
摘要 |
<p>Large values of avalanche current are avoided in a gas discharge display panel by "staggering" in time the application of the sustain voltage waveforms to different portions of the display panel. A plurality of individual sustain circuit modules each having two 100 v FET's are connected to a common sustain circuit module having another two 100 v FET's. The "staggered" sustain operation is provided by selectively controlling the individual sustain circuit modules. The individual and common sustain circuit modules combine to alternatively produce 0-200 v square wave or a 0-100-200 v return-to-midpoint waveform by selectively controlling the FET's.</p> |
