Abstract
Описана схема управления разверткой, которая содержит модуль управления повышением, повышающий модуль, понижающий модуль, модуль поддержки понижения, модуль нисходящей передачи и ускоряющий конденсатор; при генерировании сигнала уровня развертки модулем управления повышением в модуле управления повышением и модуле поддержки понижения используют постоянное напряжение высокого логического уровня для предотвращения явления утечки тока; и в понижающем модуле используют сигнал развертки текущего уровня для предотвращения явления утечки тока. Таким образом, можно эффективно предотвратить явление утечки тока.
