Verfahren zur Regenerierung von Mikrospitzen einer flachen Anzeigetafel |
摘要 |
<p>The grid is biased to a regeneration potential distinctly greater than the nominal potential and the cathode is biased to a nominal potential corresponding to a maximum emission. The rows (L) of the grid are addressed in sequence during a nominal time during which the cathode columns (K) are individually addressed. At least one row, perhaps all, of the grid is biased to a the regeneration potential and all the cathode columns are at the maximum emission potential for a regeneration time distinctly greater than the nominal time. The rows are addressed by a pulsed signal (Hreg) whose mark is distinctly longer than the nominal time and distinctly shorter than the space time to avoid overheating.</p> |
